Patent Description:
As an information display device including a display panel and a surface member, there is known an information display device that displays contents displayed on the display panel through the surface member (refer to Japanese Patent <CIT>).

<CIT> relates to a display device covered by a scattering member combined with a reflecting member as a disguising element.

<CIT> relates to a display device including a display covered with a half-transparent polarizing mirror and a scattering surface.

<CIT> relates to a display apparatus including a display panel covered by an opaque screen, which allows for viewing the displayed.

<CIT> relates to a display device covered by a semi-opaque overlay.

It is possible to improve the designability of a space by covering the display panel with a surface member and displaying only the information to be displayed via the surface member on the wall without making the user feel the presence of the display panel. However, in order to make the display panel invisible through the surface member, it is necessary to suppress external light transmitted through the surface member, and when the light transmitted through the surface member from the display panel attenuates, there is a concern that it is difficult to see the information displayed on the display panel.

An information display device according to the disclosure aims to allow a user to see information from a display panel displayed on a surface member without being aware of the presence of the display panel.

The invention is defined by the independent claim.

Hereinafter, embodiments will be described in detail with reference to the drawings as appropriate. However, there is a case where an unnecessary detailed description is omitted. For example, there is a case where the detailed description of a well-known item or a redundant description of substantially the same configuration is omitted.

In addition, the attached drawings and the following description are provided in order to enable those skilled in the art to fully understand the disclosure, and are not intended to limit the subject matter described in the claims.

In the following description, a "front surface side" or a "front side" of an information display device is a side on which ambient light or external light is incident or a side closer to a user who sees the information display device, unless otherwise specified. A "back surface side" or a "back side" is a side opposite to the "front surface side" or the "front side", and is a side where light of a display panel is emitted or guided.

In the information display device according to the disclosure, a surface member that covers the entirety or a part of a wall surface having a designability and light transmitting properties is disposed on a front surface of the display panel. The information display device according to the disclosure can realize a seamless design having no seam between a wall surface and an information display region, and can also realize an information display device having operability.

In the following description, a case where the information display device is used in an aircraft is employed as an example.

<FIG> illustrates a usage environment of information display device <NUM> according to the embodiment.

In the usage environment in the embodiment, information display device <NUM> is disposed on wall surface <NUM> which is a part of the interior of the aircraft. Information display device <NUM> transmits light of the display panel from the back side of surface member <NUM> and displays information (content information, character information, image, video, and the like) in display region 1a on surface member <NUM>. User <NUM> can operate an operation screen displayed in display region 1a of surface member <NUM> to display and change information and make a request to a crew.

Hereinafter, an outline of the configuration and operation of information display device <NUM> of the embodiment will be described with reference to <FIG> and <FIG>. Information display device <NUM> of the embodiment includes display device <NUM> installed behind surface member <NUM>. Information such as contents or characters displayed on the display surface of display device <NUM> is displayed on the surface of surface member <NUM> through surface member <NUM> and presented to user <NUM>.

<FIG> illustrates a schematic configuration of display device <NUM> of the embodiment. Display device <NUM> includes touch panel <NUM>, CPU <NUM>, and display panel <NUM>. Touch panel <NUM> detects an input of user <NUM> via surface member <NUM> based on a change in electrostatic capacitance, pressure, or light, processes the input in CPU <NUM>, and controls display device <NUM>.

Touch panel <NUM> may be a touch sensor. The touch panel or the touch sensor is not essential as a configuration element of display device <NUM>. In a case where there is no touch panel or a touch sensor, display device <NUM> cannot directly receive the operation from the user, but can display a logo or a symbol on wall surface <NUM> or use as lighting or the like hidden on wall surface <NUM>.

<FIG> is a schematic sectional view of information display device <NUM> of the embodiment. Information display device <NUM> includes surface member <NUM>, reflection member (half mirror) <NUM>, touch panel <NUM>, and display panel <NUM>.

Surface member <NUM> is a member disposed on the surface of the wall in the aircraft cabin, and is a surface member that covers a part or the entirety of a wall, a floor, an armrest, and a table of a seat shell. The range in which the information is displayed through surface member <NUM> is a range that is reached by the hand when the user is in operation, a range (including, for example, a bedside) reached by the line of sight from a passenger in order to deliver the information to the passenger, and further, a range reached by the line of sight from the crew (cabin attendant).

Surface member <NUM> is a material having a certain level of translucent properties, and has a plate or film shape. A surface area of surface member <NUM> is configured to be larger than the display area of display panel <NUM>. The material of surface member <NUM> is a material having the same or similar surface to that of the material that covers the surface of wall surface <NUM>. By embedding display panel <NUM> in wall surface <NUM> and covering the display panel with surface member <NUM>, information can be displayed on wall surface <NUM> without making user <NUM> aware of the presence of display panel <NUM>. Further, by making the surface area of surface member <NUM> larger than the display area of display panel <NUM>, display region 1a of display panel <NUM>, that is, the border or outer edge of the display area of display panel <NUM> becomes difficult to be visually recognized from the user. In addition, by covering the entire wall surface <NUM> with surface member <NUM>, it is possible to completely eliminate the seam around display panel <NUM>.

Accordingly, user <NUM> can be made unaware of the presence of display panel <NUM>. Surface member <NUM> is made of a genuine material such as wood, cloth, leather, stone, or the like, a film material simulating the genuine material, or a transparent or translucent material of which a surface is decorated by painting or printing, and accordingly, it is possible to display information without making the user feel the presence of display panel <NUM> from the appearance.

Surface member <NUM> may be configured to partially have light transmitting properties, not to transmit light to other area, and to display only necessary areas. For example, by providing a part having light transmitting properties in a specific symbol shape, a clearer symbol can be displayed. The light transmittance of surface member <NUM> is, for example, <NUM>% to <NUM>%. Since surface member <NUM> is configured to have such a light transmittance, the light transmitted from the front side to the back side of surface member <NUM> is suppressed such that display panel <NUM> itself becomes invisible from the outside, and it is possible to make the display by display device <NUM> sufficiently visually recognizable even through surface member <NUM>.

Surface member <NUM> may have a certain hard coating (not illustrated) on the side opposite to the side (back side) where display panel <NUM> is present, that is, on the front side. The user frequently touches the front side of surface member <NUM> for operation using touch panel <NUM>. In particular, in a case where information display device <NUM> is used in equipment and the like in the aircraft, an unspecified number of people perform a touch operation. Accordingly, it is preferable that the hard coating has a hardness of, for example, <NUM> (JIS standard) or higher. Thereby, damage can be prevented. The hard coating may be a thin layer to keep the feeling of surface member <NUM>. The hard coating has a thickness of, for example, <NUM> to <NUM>.

Reflection member <NUM> is a material such as a half mirror, and has a characteristic of reflecting external light but transmitting light from display panel <NUM> on the inside. By inserting reflection member <NUM> between surface member <NUM> and display panel <NUM>, the boundary between wall surface <NUM> and the display region can be made more difficult to be seen. While the presence of display panel <NUM> itself is prevented from being seen through surface member <NUM> by the external light reflection characteristic of reflection member <NUM>, the display contents of display panel <NUM> can be presented to the user by the characteristic of transmitting the light of reflection member <NUM>.

In addition, when surface member <NUM> has a sufficient external light reflection characteristic and a light transmission characteristic of the internal light source emitted from display panel <NUM>, reflection member <NUM> may be omitted.

Surface member <NUM> and reflection member <NUM> may be formed of an insulator such that touch panel <NUM> can be operable. In this case, the sheet resistance is preferably higher. This is because, when there is no sufficient resistance value, false recognition or the like of a touch detection position on touch panel <NUM> is induced. In order to sufficiently ensure the performance of touch panel <NUM>, it is preferable that surface member <NUM> and reflection member <NUM> have a sheet resistance value of, for example, <NUM> megaohms or more.

Reflection member <NUM> may be formed by a metal vapor-deposited film that can transmit electromagnetic waves or a film that can produce a metallic luster by laminating a resin material. In this case, an indium-deposited film, a film formed by laminating a PET material, or the like is preferable. Accordingly, it becomes easy to ensure both the performance of touch panel <NUM> and to hide display panel <NUM>.

Display device <NUM> may have functions, such as wireless charging, near field communication (NFC), and lighting, behind wall surface <NUM> instead of touch panel <NUM> or in addition to touch panel <NUM>. With such a configuration, it is possible to expect an effect of enhancing convenience for the user or the maintenance person, and enhancing a presentation effect of displaying information.

Since the surface member is arranged on the front surface, it is preferable that the touch panel <NUM> is configured by using a capacitance type in particular. In general, for displays with a size of <NUM> inches or less, a sensor pitch of about <NUM> is usually selected for capacitive touch sensor. However, in order to detect the touch operation through the thickness of the surface member as in the present embodiment, it is preferable to set the sensor pitch to <NUM> or more, preferably <NUM> to <NUM>. Also, on the input screen provided to the user, it is preferable to use icons of <NUM> square or more for each button. This is because the detection accuracy is reduced due to the large sensor pitch.

With these settings, even when the touch operation by the user's finger or the like is performed from the front side of the surface member <NUM>, the operation can be sufficiently detected, and a natural operation feeling can be provided to the user.

Display panel <NUM> is, for example, a liquid crystal display. Display panel <NUM> includes a color filter, a liquid crystal panel, and a light source such as an LED (any of these is not illustrated). A display image including predetermined information, the color of background, or a pattern is displayed to be visible on surface member <NUM> by light BL from a light source such as an LED. Display panel <NUM> may be either a non-light-emitting display having a light source or a light-emitting display. As display panel <NUM>, an OLED display, a matrix LED display, or other display devices provided with other light sources may be used.

Display panel <NUM> is adjusted such that the screen luminance after transmission through surface member <NUM> is <NUM> cd/m^<NUM> or less preferably about 80cd/m^<NUM> when the display panel <NUM> is turned on. Accordingly, from the front side of surface member <NUM>, while display panel <NUM> itself becomes invisible from the outside, it is possible to make the display by display panel <NUM> sufficiently visually recognizable even through surface member <NUM>, and to prevent the display panel from being overly dazzled.

In order to hide the display panel <NUM> and the bezel around the display panel <NUM> from the front side of the surface member <NUM>, the total visible light transmittance of the surface member <NUM> and the reflecting member <NUM> is assumed to be <NUM>% to <NUM>%, preferably around <NUM>. In addition, in order to make the display on the surface member <NUM> to be <NUM> cd / m ^ <NUM> or less, preferably about <NUM> cd / m ^ <NUM>, the screen brightness of the display panel <NUM> itself may be adjusted to <NUM> cd / m ^ <NUM> or more preferably <NUM>,000cd/m^<NUM>.

When the power of information display device <NUM> is turned on, display panel <NUM> is illuminated to display information on the display surface. At this time, only the information displayed on the display surface is visible to the user through surface member <NUM>. Meanwhile, when the power of information display device <NUM> is turned off, display panel <NUM> is turned off. At this time, display panel <NUM> becomes hardly seen from the user through surface member <NUM>, that is, invisible. In addition, even when the power of information display device <NUM> is turned on and display panel <NUM> is illuminated, a area (background color area) of the display on which information is not displayed becomes hardly seen from the user via surface member <NUM>, that is, invisible.

In a case where information display device <NUM> is used in an aircraft, as the information or the contents of the operation presented to user <NUM> (for example, a passenger or a crew), for example, transit information, seat lighting control, audio control, and DO NOT DISTURB setting, entertainment equipment control, seat reclining, attendant call and cancellation thereof, weather information, information on flight time or local time, presentation of seat number, display of lavatory availability, seat belt sign, door mode state display, and the like can be considered. Further, a function to turn off or to adjust brightness of the display of wall surface <NUM>.

Accordingly, in a narrow space such as a space around a seat in the aircraft, the user can be provided with a control unit such as seat reclining, air conditioning, and lighting while maintaining a simple and high-quality design in which there is no prominent display terminal or operation terminal. A controller having multiple functions or a function as a terminal for displaying information can be imparted to the wall having a designability.

In addition, since there are no physical buttons on the wall surface, when considering a usage by many and unspecified users, there is no case where malfunction is caused by spilling liquids such as juice, and the like, and it is possible to easily clean up since there is no unevenness.

Further, since an operation screen or information is displayed on wall surface <NUM> that appears to be empty for user <NUM> as necessary, it is possible to give user <NUM> a surprise. In particular, by expressing combination with surface member <NUM>, for example, it is possible to make the wood look protruded, or to make it look as if there are an object that is not actually present or an imaginary object on the wall, and a spatial presentation for user <NUM> is also possible.

In information display device <NUM> according to the embodiment, surface member <NUM> having a designability and light transmitting properties is disposed in front of display panel <NUM>, and surface member <NUM> covers the entire wall surface <NUM> or at least a surface larger than display panel <NUM>. When using information display device <NUM> according to the embodiment, it is possible to realize a seamless design having no seam between wall surface <NUM> and the information display region. Accordingly, it is possible to provide a user with an information display device in which characters, images, and the like appear on wall surface <NUM> and through which the user can perform an action such as an operation.

In addition, when the design permits, there may be a boundary between surface member <NUM> that covers display panel <NUM> and the other part of wall surface <NUM>. In this manner, it is possible to simply perform removal from the viewpoint of maintenance properties and the like.

Information display device <NUM> according to the embodiment can also have the following configuration.

<FIG> illustrates a usage environment of information display device <NUM> according to the modification example.

In the usage environment according to the modification example, information display device <NUM> is disposed on seat <NUM>. Information display device <NUM> according to the modification example is installed in the vicinity of the periphery of seat monitor <NUM> and displays information at a position that can be seen from user <NUM> (for example, a passenger) without largely moving the line of sight from seat monitor <NUM>. Accordingly, it is possible to realize an information display device which is easy to use and capable of minimizing the operation of the line of sight and neck of user <NUM>. The basic operation of information display device <NUM> according to the modification example is the same as that of the Embodiment <NUM> described above.

<FIG> is a configuration view of a system for operating information display device <NUM> according to the modification example. CPU <NUM> control display panel <NUM> disposed around seat monitor <NUM> to display necessary or useful information for the user based on the information from in-flight server <NUM>. For example, the information includes a fasten seat belt sign, information on the availability of lavatory, information on flight time, and the like.

With the above-described operation, in the modification example, it becomes possible to present an operation screen at a position that is easily seen from user <NUM>, to make the operator aware, or to realize an information display device that is more easily used.

In the usage environment according to the modification example, information display device <NUM> is disposed on ceiling <NUM>. Information display device <NUM> is installed on a ceiling of a cabin or ceiling <NUM> of a seat compartment, and can display a starry sky as if user <NUM> is under an outdoor sky, or can display an advertisement. Accordingly, it is possible to realize an information display device that can alleviate the psychological tension and the like that user <NUM> receives in a narrow space in the cabin, and can effectively provide an advertisement. The basic operation of the information display device according to the embodiment is the same as that of Embodiment <NUM>.

<FIG> is a configuration view of a system for operating information display device <NUM> according to the modification example. CPU <NUM> displays a night sky or blue sky video or an advertisement on the ceiling on display panel <NUM> based on information from in-flight server <NUM>. Depending on the information to be displayed, connection to in-flight server <NUM> may not be required.

With the above-described operation, in the modification example, it becomes possible to realize an information display device that alleviates the tension of the user and gives the user a surprise.

<FIG> is a schematic sectional view of information display device <NUM> according to the modification example. The information display device includes surface member <NUM>, reflection member (half mirror) <NUM>, and display panel <NUM>, and does not include a touch panel since no touch screen operation is required.

In the usage environment according to the modification example, information display device <NUM> displays information mainly for crew <NUM> such as a cabin attendant, which is disposed on wall surface <NUM> of a cabin wall of the seat compartment. Information display device <NUM> according to the modification example can display a sign at a position that can be seen by crew <NUM> from a passage or via a camera image. Accordingly, as described in the related art, without interfering with the sense of luxury by disposing a display for displaying or a lamp on a passage, a wall, or a ceiling in the cabin, it is possible to reduce the load on crew <NUM> or to improve service for the passengers. The basic operation of the information display device according to the embodiment is the same as that of Embodiment <NUM>.

The wall surface <NUM> may be a floor, a ceiling, or a wall surface of a door of a seat compartment.

<FIG> is a configuration view of a system for operating information display device <NUM> according to the modification example. CPU <NUM> displays an attendant call, a DON'T DISTURB sign, a seat number, and the like on display panel <NUM> based on information from in-flight server <NUM>. Depending on the information to be displayed, connection to the in-flight server may not be required.

By the above-described operation, in the modification example, it is possible to realize an information display device that can reduce the workload on the crews <NUM> or improve the service for the passengers without interfering with the sense of luxury.

As one of usages of information display device <NUM> according to the modification example, the passenger name and the seat number may be displayed at the seat compartment entrance at the time of boarding and the like, and the seat number and the passenger name may not be displayed at other times. Accordingly, while improving the convenience of the passengers when boarding, the original decorative wall surface can be used without displaying the seat number or the passenger name at other times. As a result, it is possible to maintain a sense of luxury as a space while considering the privacy of passengers.

<FIG> is a schematic sectional view of information display device <NUM> according to the modification example. Information display device <NUM> includes surface member <NUM>, reflection member (half mirror) <NUM>, touch panel <NUM>, and display panel <NUM>, and each member is the same as those in Embodiment <NUM>. Further, similar to Embodiment <NUM>, information display device <NUM> may not include reflection member <NUM> and/or touch panel <NUM>.

In the usage environment according to the modification example, information display device <NUM> is disposed on a wall surface of a work area of crew <NUM>, such as a galley in an aircraft, or on door surface <NUM> of a container. Information display device <NUM> can display information at a position where crew <NUM> can see the information while working. Until now, it was necessary for crew <NUM> to confirm requests, orders, and the like from each seat using an information terminal (not illustrated) near the door. However, according to information display device <NUM> according to modification example, crew <NUM> can grasp requests from each seat and input a response status while performing the work of serving and preparing, and can improve work efficiency. Furthermore, an information display device can be realized without deteriorating the sense of luxury of the galley used as a sales space these days. The basic operation of the information display device according to the embodiment is the same as that of Embodiment <NUM>.

Door surface <NUM> may be a wagon door or a wall surface which are disposed on a floor, a ceiling, or a galley.

<FIG> is a configuration view of a system for operating information display device <NUM> according to the modification example. CPU <NUM> controls display, on display panel <NUM>, the order of drinks, request for blankets, and the like from the passenger, call information, status of the request (response history), and the like, with the accompanying seat number, and the like, based on the information from in-flight server <NUM>. Crew <NUM> can operate touch panel <NUM> to input necessary information. Depending on the information to be displayed, connection to the in-flight server may not be required.

By the above-described operation, in the modification example, it is possible to realize an information display device capable of reducing the work load on crew <NUM> or improving the service for the passengers without interfering with the sense of luxury in the galley.

By forming information display device <NUM> according to the modification example to be thin, it is possible to make effective use of the space of the container.

Surface member <NUM> can be formed of a waterproof material. Accordingly, it is possible to realize a convenient information display device that can be safely operated even in a case of using water in the work area of crew <NUM>.

In the usage environment according to the modification example, information display device <NUM> is disposed, for example, on seat <NUM> or the wall of the seat compartment. Information display device <NUM> is disposed at a position that is difficult to be seen or invisible to a third party (other passenger or crew and the like), such as a lavatory availability sign. Although seat <NUM> or the wall of the seat compartment is a wall that usually give a sense of luxury, the availability of the lavatory is displayed such that only user <NUM> can understand in a case where a desire for excretion is felt. There are many cases where the display sign indicating the vacancy of the lavatory is installed on the upper area of the wall in the related art, but by installing information display device <NUM> at a place where the line of sight easily reaches in seat <NUM> or the compartment, user <NUM> can understand the state of the lavatory without greatly moving the line of sight or the neck, and an effect of enhancing convenience of the user is expected. In addition, when the availability of the lavatory is constantly displayed, the sense of luxury or designability deteriorates, but information display device <NUM> according to the modification example does not make the user feel the presence of the device while the device is unnecessary and the information can be seen only to the user regarding the contents that are not known to a third party such as other passengers.

<FIG> is a configuration view of a system for operating information display device <NUM> according to the modification example. CPU <NUM> controls display panel <NUM> to display the availability of the lavatory and the like based on the information from in-flight server <NUM>. Depending on the information to be displayed, connection to the in-flight server may not be required.

In the usage environment according to the modification example, information display device <NUM> is disposed, for example, on seat <NUM> or the wall of the seat compartment. Information display device <NUM> is disposed at a position within a distance of <NUM> around the user's face. Normally, since the information display monitor emits light by itself, it is dazzling to the user when it is placed around the face, and there will be a problem that sleep is disturbed, for example. In addition, the heat of the monitor is transmitted to the user, which may cause discomfort.

However, since the display device is arranged behind the surface member <NUM> in the information display device <NUM>, information can be displayed from the vicinity without giving discomfort to the user in terms of brightness and temperature. Therefore, at the time such as at night, it is possible to present the information without giving discomfort to the user even in the vicinity of the face. The vicinity of the face here is higher than the position of the user's shoulder and forward of the position of the ear, and is a distance within <NUM> from the side of the cheek and the eyes around the face as starting points is assumed. Similarly, when the user puts the backrest of the seat down to the bed mode, that is, even when the information is displayed at the position where the user can see directly when the user takes the sleeping posture, the user may not feel uncomfortable.

In the embodiment illustrated in <FIG>, information display device 1B including surface member <NUM> and display device <NUM> has an attachment feature to cabin structure (wall, door, monument and the like) <NUM>.

Information display device 1B is used in any usage environment similar to the above-described embodiment. The description of information display device 1B having the same configuration and function as those of the above-described embodiment will be omitted, and the same reference numerals will be given to the same configuration members.

The attachment feature includes a structural body 100a, and structural body 100a has retainers 105a and 105b. Structural body 100a is attached to the back side of surface member <NUM> at a position that does not overlap the display area of display panel <NUM>. Retainers 105a and 105b are provided on the back side and/or the side portion of structural body 100a or surface member <NUM> at positions that are invisible from the front side of surface member <NUM>, and retain information display device 1B to structure <NUM>. Retainers 105a and 105b and/or other locations are fixed with screws <NUM> and the like.

Retainers are preferably provided on at least one side, and more preferably provided on a plurality of sides in different directions similar to retainers 105a and 105b illustrated in <FIG>.

At least surface member <NUM> side of structural body 100a is colored with substantially the same color (for example, black) as the background color of the display surface when display panel <NUM> is turned off or turned on. Accordingly, it is possible to prevent the boundary between structural body 100a and display panel <NUM> from being seen through surface member <NUM>.

Information display device 1B can be configured to be easily detached from and attached to structure <NUM>, and an information display device that is easy to maintain can be realized. For example, a configuration in which the fixing on retainer 105b side among retainers illustrated in <FIG> is released and information display device 1B is attached or detached by rotating information display device 1B with locker 105a as a fulcrum can also be employed.

Desirable performances for the display and touch panel used in this embodiment are the same as those described in the first embodiment.

Information display device 1C according to the embodiment illustrated in <FIG> has a configuration in which an integrated unit of a film having a designability and light transmitting properties and a transparent fixing plate on the front side of display panel <NUM> is pressed. With such a configuration, it is possible to display and operate information as necessary while realizing a seamless design, and to make system maintenance easy.

Information display device 1C is used in any usage environment similar to those of the above-described embodiments. The description of information display device 1C having the same configuration and function as those of the above-described embodiments will be omitted, and the same reference numerals will be given to the same configuration members.

<FIG> is a schematic sectional view of information display device 1C of the embodiment. Information display device 1C includes surface member <NUM>, reflection member (half mirror) <NUM>, transparent member <NUM>, structural body <NUM>, touch panel <NUM>, display panel <NUM>, and housing <NUM>. In order to sufficiently exhibit the effect of hiding the presence of display panel <NUM> and the effect of reflection member <NUM> for transmitting the contents displayed by display panel <NUM> and displaying the contents on surface member <NUM>, it is preferable that reflection member <NUM> is disposed at a position close to surface member <NUM>. This is because, when there is a gap between reflection member <NUM> and surface member <NUM>, there is a possibility that the light from display panel <NUM> transmitted through reflection member <NUM> is diffused and displayed on surface member <NUM> with blur. However, in a case where the requirement for display quality is not so high, the positions of reflection member <NUM> and transparent member <NUM> may be reversed. As long as the function as the information display device is satisfied, the order of the disposition may be any order.

Surface member <NUM> may not have a surface area larger than that of display panel <NUM>.

Transparent member <NUM> is a plate having a certain hardness. Transparent member <NUM> is preferably as thin as possible in order to reduce the blur of the display on surface member <NUM>, for example, approximately <NUM> to <NUM> and more preferably approximately <NUM> to <NUM>.

In order to make toch panel <NUM> operable, it is preferable that surface member <NUM> and reflection member <NUM> are formed by an insulator similar to Embodiment <NUM>. Further, for the same reason, it is preferable that transparent member <NUM> is also similarly an insulator and has a sheet resistance value of <NUM> megaohms or more.

The height of structural body <NUM> is preferably formed such that space <NUM> is as small as possible. This is because, by shortening the distance between display panel <NUM> and reflection member <NUM> and surface member <NUM>, diffusion of light can be suppressed, and the blur of display on surface member <NUM> can be minimized. Space <NUM> is preferably as small as possible. Preferably, a state where touch panel <NUM> is press fitted against transparent member <NUM> without any gap, for example, a state of <NUM> or a state close thereto is preferable.

Housing <NUM> is fixed to structural body <NUM> by fixing units such as screws. By fixing transparent member <NUM> to structural body <NUM>, surface member <NUM> and reflection member <NUM> can be installed on the display surface side of display panel <NUM>. Accordingly, information display device 1C can be configured without directly pasting surface member <NUM> or reflection member <NUM> to touch panel <NUM> or display panel <NUM>. However, in a case where surface member <NUM> or reflection member <NUM> alone has sufficient strength, transparent member <NUM> can be omitted.

With the above-described configuration, information display device 1C according to the embodiment can be disposed without making the user feel the position and the presence of display panel <NUM>. Further, in information display device 1C, surface member <NUM>, reflection member <NUM>, and transparent member <NUM> can be collectively detached from structural body <NUM>. Accordingly, without taking off the entire wall on which information display device 1C is attached, only display panel <NUM> or touch panel <NUM> can be detached, and display <NUM> can be easily accessed and can be repaired or replaced. Further, after the repair or the replacement of information display device 1C, surface member <NUM>, reflection member <NUM>, and transparent member <NUM> can be reused.

In information display device 1D according to the embodiment, at least the front surface of structural body <NUM> and/or a region (a region that surrounds the display surface) other than the display surface of display panel <NUM> between display panel <NUM> and surface member <NUM>, have a colored layer colored with substantially the same color (for example, black) as the background color of the display surface when display panel <NUM> is turned off or turned on. Hereinafter, examples of such a colored layer will be specifically described.

Information display device 1D is used in any usage environment similar to the above-described embodiment. The description of information display device 1D having the same configuration and function as those of the above-described embodiments will be omitted, and the same reference numerals will be given to the same configuration members.

Information display device 1D according to the embodiment is different from Embodiment <NUM> in that mask print layer <NUM> (an example of the colored layer) is provided at least a part other than the display surface of display panel <NUM>. With this configuration, it is possible to prevent see-through of a part having no display panel <NUM>, and when viewed from the front surface side of surface member <NUM>, the display surface of display panel <NUM> and other regions are made the same, it is possible to make it difficult to see display panel <NUM>.

<FIG> is a schematic sectional view of information display device 1D of the embodiment. Information display device 1D includes surface member <NUM>, reflection member (half mirror) <NUM>, transparent member <NUM>, mask layer <NUM>, structural body <NUM>, touch panel <NUM>, display panel <NUM>, and housing <NUM>. The function of information display device 1D is satisfied even when reflection member <NUM> is disposed between transparent member <NUM> and mask layer <NUM>.

Housing <NUM> is fixed to structural body <NUM> by fixing units such as screws. By fixing transparent member <NUM> to structural body <NUM>, surface member <NUM> or reflection member <NUM> can be installed on the display surface side of display panel <NUM>. Accordingly, information display device 1C can be configured without directly pasting surface member <NUM> or reflection member <NUM> to touch panel <NUM> or display panel <NUM>. However, in a case where such a configuration is employed, while the region where display panel <NUM> is located transmits light, the region where structural body <NUM> is located does not transmit light on the surface of surface member <NUM>, and accordingly, the boundary part between display panel <NUM> and structural body <NUM> is visible. In order to prevent this, in the embodiment, mask layer <NUM> is disposed at the boundary part.

Mask layer <NUM> is disposed so as to surround the display surface of display panel <NUM>. Mask layer <NUM> is preferably colored with substantially the same color as the background color of a region other than the region that displays the information, which is a display surface of display panel <NUM> when display panel <NUM> is turned off or when display panel <NUM> is turned on. Accordingly, the boundary between display panel <NUM> and structural body <NUM> can be made prominent through surface member <NUM>.

The region where mask layer <NUM> is provided is preferably provided not only on structural body <NUM> but also on a region excluding the region of the display surface where display panel <NUM> displays information. In particular, the part having no mask layer <NUM> may be smaller than the entire region of display panel <NUM> such that the region where mask layer <NUM> is provided covers the edge of display panel <NUM>. By doing so, it can be difficult to understand the difference in appearance between display panel <NUM> and the other regions when wall surface <NUM> (<FIG>) viewed from user <NUM> is viewed, that is, when the wall surface is viewed from the front side of surface member <NUM>.

With the above-described configuration, it is possible to realize an information display device that does not make the user feel the position and the presence of the display panel.

As illustrated in <FIG>, information display device 1D-<NUM> (<FIG>) according to Embodiment <NUM> may be configured such that the corners of inner edge 83b of mask layer <NUM> that surrounds display surface <NUM> of display panel <NUM> are formed in an arc shape. Alternatively or additionally, mask layer <NUM> may be colored by applying a gradation from outer edge 83a to inner edge 83b.

Accordingly, in a case of viewed from the front surface side of surface member <NUM>, the difference in appearance between the part where display panel <NUM> is located and the other part can be made more difficult to understand.

In the modification example, when user <NUM> sees from surface member <NUM>, the part where mask layer <NUM> is not installed is formed in a polygonal shape with rounded corners, or a circular or elliptical shape. Display panel <NUM> is usually rectangular, and its four corners are almost right angles. However, when the display surface is rectangular due to a difference in appearance when viewed from the front surface side of surface member <NUM>, user <NUM> inevitably feels that there is a display on the rear surface. Here, the part where mask layer <NUM> is not installed is formed into a polygonal shape with rounded corners, or a circular or elliptical shape such that user <NUM> cannot see the rectangular shape on the display surface. Accordingly, user <NUM> does not recognize that display panel <NUM> is behind wall surface <NUM>. Therefore, only the displayed information appears to emerge from wall surface <NUM>, and user <NUM> can be given a fresh surprise.

Furthermore, mask layer <NUM> may be colored by applying a gradation from outer edge 83a illustrated in <FIG> to inner edge 83b. In this case, by gradually fading the color toward display surface <NUM>, that is, inward, that is, by increasing the light transmittance, at the boundary part between mask layer <NUM> and display surface <NUM> of display panel <NUM>, the difference in appearance between display surface <NUM> and the other parts when viewed from the front surface side of surface member <NUM> becomes more difficult to understand. Accordingly, it is possible to realize a configuration that does not make user <NUM> aware of the presence of display panel <NUM>.

<FIG> illustrates a modification example of information display device 1D attached by the structural body. <FIG> is a schematic sectional view of information display device 1D-<NUM> according to the modification example. Information display device 1D-<NUM> includes surface member <NUM>, transparent member <NUM>, mask layer <NUM>, structural body <NUM>, reflection layer (half mirror) <NUM>, touch panel <NUM>, display panel <NUM>, and housing <NUM>.

The thickness from surface member <NUM> to reflection layer <NUM> is preferably as thin as possible in order to minimize the blur of the display on surface member <NUM>. The thickness is, for example, approximately <NUM> to <NUM>, preferably approximately <NUM> to <NUM>.

In order to make touch panel <NUM> operable, it is preferable that surface member <NUM>, transparent member <NUM>, and reflection layer <NUM> are formed by an insulator similar to Embodiment <NUM>.

In a case where reflection layer <NUM> is disposed in a region that does not overlap structural body <NUM> as in the modification example, transparent surface member <NUM> has a different appearance when viewed from the front surface side by an object on the lower layer, that is, on the back side. Since information display device 1D-<NUM> includes reflection layer <NUM>, the information displayed on display panel <NUM> is displayed on surface member <NUM> while hiding the presence of display panel <NUM>. However, the appearance when viewed from the front surface differs between the place where reflection layer <NUM> is located under surface member <NUM> and the other places. Here, in the modification example, by coloring mask layer <NUM>, for example, white or gray, the appearance of wall surface <NUM> (<FIG>) seen from user <NUM> and the appearance of display region 1a (<FIG>) are prevented from becoming different from each other. The color of mask layer <NUM> is changed in accordance with the specifications of surface member <NUM>, the luminance of the environment, the color of structural body <NUM>, and the like. In a case of white or gray, an effect can be expected in which the color of a certain place of reflection layer <NUM> looks similar to other places.

As illustrated in <FIG>, in information display device 1E according to the embodiment, slight-adhesive layer <NUM> that can be peeled off again is disposed in front of display panel <NUM>, and surface member <NUM> having a designability and light transmitting properties is disposed on the front side. Information display device 1E according to the embodiment reduces the blur on the display while realizing a seamless design having no seam between the wall surface and the information display region, and provides a comfortable operation feeling without an air gap in front of the touch panel.

Information display device 1E is used in any usage environment similar to the above-described embodiment. The description of information display device 1E having the same configuration and function as those of the above-described embodiments will be omitted, and the same reference numerals will be given to the same configuration members.

<FIG> is a schematic sectional view of information display device 1E of the embodiment. Information display device 1E includes surface member <NUM>, slight-adhesive layer <NUM>, reflection layer (half mirror) <NUM>, touch panel <NUM>, display panel <NUM>, structural body <NUM>, and housing <NUM>. Information display device 1E is fixed to structural body <NUM> with housing <NUM>, and structural body <NUM> is fixed to fixing member <NUM>. Information display device 1E may not include reflection layer <NUM> and/or touch panel <NUM> in accordance with the function.

Slight-adhesive layer <NUM> is a member such as a film having the light transmitting properties and having a weak or slight adhesiveness on which both surfaces or one of the surfaces can be peeled off again. Slight-adhesive layer <NUM> prevents a gap (air gap) between the lower member (reflection layer <NUM> in the illustrated example, touch panel <NUM> in a case where reflection layer <NUM> is not provided, and display panel <NUM> in a case where touch panel <NUM> is not provided) and surface member <NUM>. With the configuration, the information displayed on display panel <NUM> can be displayed on surface member <NUM> without the blur as much as possible. In particular, in a case where information display device 1E includes touch panel <NUM>, the operation feeling of touch panel <NUM> deteriorates when the gap (air gap) is present. However, the presence of slight-adhesive layer <NUM> can improve the operation feeling of touch panel <NUM> and realize a user-friendly information display device.

Since slight-adhesive layer <NUM> can be peeled off again, when display device <NUM> breaks down, only display device <NUM> can be detached from the wall without breaking surface member <NUM>, and accordingly, it is possible to make the maintenance easy. In the example of <FIG>, display device <NUM> can be detached from surface member <NUM> with housing <NUM> by removing fixing member <NUM> disposed on the rear surface of housing <NUM>. Accordingly, display device <NUM> can be replaced or repaired without breaking or damaging surface member <NUM>.

The specific example here is merely an example, fixing member <NUM> may not be provided on the rear surface, a fixing arm may be projected from housing <NUM>, and the arm may be fixed to structural body <NUM>. In this case, there are various fixing members, such as a method in which there is an attaching screw on the side surface of housing <NUM>, and after fixing housing <NUM> to structural body <NUM> with the attaching screw, structural body <NUM>, housing <NUM>, and display device <NUM> are collectively pressed against surface member <NUM> and fixed.

Slight-adhesive layer <NUM> may not have the light transmitting properties as long as the slight-adhesive layer has an area smaller than the area of the display surface of display panel <NUM> and a shape that avoids display contents. However, when the area is equal to or larger than the area of the display surface, the configuration that has the light transmitting properties and does not allow bubbles to enter is preferable. Accordingly, it is possible to prevent the information displayed on surface member <NUM> from blurring, and to realize an information display device which sharply displays information and is easily used by the user.

Furthermore, slight-adhesive layer <NUM> may be formed by imparting a slight adhesive to the surface of a lower layer member (reflection layer <NUM> in the illustrated example, and touch panel <NUM> in a case where there is no reflection layer <NUM>). Otherwise, the slight adhesive may be imparted only to the front side of slight-adhesive layer <NUM>, that is, only to surface member <NUM> side. However, as described above, by realizing a sheet on which a slight adhesive is imparted on both surfaces of the film having the light transmitting properties, in a case where there is damage or intrusion of dust due to peeling during the maintenance, it is possible to replace display device <NUM> only by replacing the sheet.

Reflection layer <NUM> is a material such as a half mirror, and reflects the external light, but transmits light from display panel <NUM> on the inside. By disposing reflection layer <NUM> between surface member <NUM> and display panel <NUM>, the boundary between wall surface <NUM> and display region 1a can be made more difficult to understand as illustrated in <FIG>. While the presence of display panel <NUM> itself is prevented from being seen through surface member <NUM> by the external light reflection characteristic of reflection layer <NUM>, the display contents of display panel <NUM> can be presented to the user by the light transmission characteristic.

In addition, when surface member <NUM> has the sufficient external light reflection characteristic and the light transmission characteristics of the internal light source emitted from display panel <NUM>, reflection layer <NUM> may be omitted.

Surface member <NUM>, slight-adhesive layer <NUM>, and reflection layer <NUM> are insulators such that touch panel <NUM> can operate, and preferably have a higher insulation resistance value.

Reflection layer <NUM> may be formed by a metal vapor-deposited film that can transmit electromagnetic waves or a film that can produce a metallic luster by laminating a resin material. In particular, an indium or tin-deposited film, a film formed by laminating a PET material, or the like is preferable. Accordingly, it becomes easy to ensure both the performance of touch panel <NUM> and to hide display panel <NUM>.

Fixing member <NUM> is a sheet metal, a plastic component, or the like, and has a function of pressing display device <NUM> against surface member <NUM>. Since slight-adhesive layer <NUM> or the weak-adhesive layer itself does not have a bonding force enough to fix display device <NUM> to surface member <NUM>, the layers are used as a unit that further presses slight-adhesive layer <NUM> against surface member <NUM>. Fixing member <NUM> may be a plate material such as a sheet metal or a plastic component. Further, the same effect can be obtained even when the arm is projected from housing <NUM> and fixed to structural body <NUM>. Furthermore, a configuration in which display device <NUM> is pressed against surface member <NUM> by assembling with structural body <NUM> in a state of being attached to a fixed component (not illustrated) by a screw hole (not illustrated) provided on the side surface of housing <NUM>, can also be realized.

In information display device 1E, the following effects can be obtained by disposing surface member <NUM>, slight-adhesive layer <NUM>, reflection layer <NUM>, touch panel <NUM>, and display panel <NUM> in this order. Since the place where reflection layer <NUM> is required is limited to the front of display panel <NUM>, the cost can be reduced by placing reflection layer <NUM> only in the place where reflection layer <NUM> is required, and the range that can be repaired by maintenance can be expanded. However, in order to sufficiently exhibit the effect of making display panel <NUM> invisible from the outside and the effect of transmitting the contents displayed on display panel <NUM> and displaying the contents on surface member <NUM>, which are the effects of reflection layer <NUM>, it is preferable that reflection layer <NUM> is disposed at a position close to surface member <NUM>. This is because, when there is a gap between reflection layer <NUM> and surface member <NUM>, there is a possibility that the light transmitted through reflection layer <NUM> from display panel <NUM> is diffused and displayed on surface member <NUM> with blur. In other words, the position of reflection layer <NUM> and the position of slight-adhesive layer <NUM> may be in the order illustrated in <FIG> or in the order reverse thereto, depending on whether the priority is given to display quality requirements or cost or maintenance.

Furthermore, in information display device 1E, since slight-adhesive layer <NUM> can be peeled off again, surface member <NUM> and display device <NUM> can be separated from each other in terms of maintenance. Accordingly, maintenance work can be performed efficiently.

As illustrated in <FIG>, information display device 1E-<NUM> according to the modification example is different from that of Embodiment <NUM> described above in that slight-adhesive layer <NUM> that can be peeled off again is adhered to front of display panel <NUM>, and surface member <NUM> having a designability and light transmitting properties and base member <NUM> having light transmitting properties are integrated with each other on the front surface, that is, on the surface side. In information display device 1E-<NUM>, in addition to the effect similar to that of Embodiment <NUM> described above, surface member <NUM> cannot be damaged during the maintenance, and further, display device <NUM> can be attached regardless of the surface state of surface member <NUM>.

In Embodiment <NUM> described above, in a case where surface member <NUM> is made of a brittle material such as cloth, for example, there is a case where surface member <NUM> is damaged even by the adhesive force of slight-adhesive layer <NUM>, or there is a case where the adhesive effect of slight-adhesive layer <NUM> is not exhibited depending on the surface state where there is the unevenness on the rear surface of surface member <NUM> by the method of weak adhesion, such as the adhesion by static electricity. Therefore, by inserting base member <NUM> between surface member <NUM> and slight-adhesive layer <NUM>, damage to surface member <NUM> by slight-adhesive layer <NUM> can be reduced, and the effect of slight-adhesive layer <NUM> can be maintained.

Base member <NUM> is a thin plate-like member having the light transmitting properties. Base member <NUM> may be fixed to surface member <NUM> by providing an adhesive layer (not illustrated) only on surface member <NUM> side so as to remain on structural body <NUM> side together with surface member <NUM> when display device <NUM> is detached. Otherwise, base member <NUM> may be fixed by being sandwiched between surface member <NUM> and structural body <NUM>. Base member <NUM> has, for example, a smooth flat surface or a surface state that allows the bubbles to escape easily such that slight-adhesive layer <NUM> functions effectively.

Base member <NUM> is preferably as thin as possible in order to reduce the blur of the display on surface member <NUM>, for example, approximately <NUM> to <NUM>, preferably <NUM> to <NUM>. In order to make touch panel <NUM> operable, it is preferable that surface member <NUM>, slight-adhesive layer <NUM>, and reflection layer <NUM> are formed by an insulator similar to Embodiment <NUM> described above. Further, for the same reason, it is preferable that base member <NUM> is also similarly an insulator and has a sheet resistance value of <NUM> megaohms or more.

Base member <NUM> may be formed by providing a region that performs mask printing and partially has no light transmitting properties, or by creating the base member with a material having no light transmitting properties and by partially providing a through-hole or a thinned part to allow light transmission. Accordingly, display region 1a (<FIG>) can be limited without processing surface member <NUM>, and leakage or transmission of extra light due to the backlight and the like of display panel <NUM> can be prevented. In this method, for example, by providing a gradation, it is also possible to make it difficult to understand the boundary between the place where the reflection layer is provided on the rear surface of surface member <NUM> and the place where the reflection layer is not provided. The function is performed as long as the size of base member <NUM> is larger than slight-adhesive layer <NUM>, but from the above-describe viewpoint, it is preferable that base member <NUM> has a surface area at least equal to or larger than the display surface of display panel <NUM>. Although base member <NUM> can be configured even on the entire surface of wall surface <NUM> (<FIG>), the addition of an extra configuration leads to an increase in cost, and accordingly, it is preferable that the area of base member <NUM> slightly exceeds not the entire surface of the wall surface with design but the surface area of the display surface of display panel <NUM>. Furthermore, in addition to the purpose of making display panel <NUM> invisible through surface member <NUM>, display panel <NUM> can also add expression in a video displayed from display panel <NUM> for various applications by providing unevenness on the surface of base member <NUM> or providing optically refracted location.

The same effect as described above can be expected even when a mask layer is provided between touch panel <NUM> and the surface of display panel <NUM>. However, since the layer is a part that changes depending on the usage environment and usage method of information display device 1E-<NUM>, it is considered that it is efficient to perform mask printing on base member <NUM> in consideration of not having to process surface member <NUM>.

Information display device 1E-<NUM> may not have to provide alight-adhesive layer <NUM> or reflection layer <NUM> by providing a reflective material or a slight adhesive on the front side of base member <NUM>. Accordingly, the number of configuration members can be reduced, the distance between surface member <NUM> and display panel <NUM> can be reduced, and the display on display panel <NUM> can be expressed more sharply. However, it is preferable to separately provide slight-adhesive layer <NUM> and reflection layer <NUM> from the viewpoint of ease of repair when display device <NUM> is removed from surface member <NUM> for maintenance as described above.

In information display device 1E-<NUM>, the following effects can be obtained by disposing surface member <NUM>, base member <NUM>, slight-adhesive layer <NUM>, reflection layer <NUM>, touch panel <NUM>, and display panel <NUM> in this order. Similar to Embodiment <NUM> described above, the position of reflection layer <NUM> may be between surface member <NUM> and base member <NUM> or between base member <NUM> and slight-adhesive layer <NUM>, but it is preferable that the members and the like are disposed in the above-describe order from the viewpoint of ease of the maintenance.

In addition, information display device 1E-<NUM> may not include reflection layer <NUM> or touch panel <NUM> for the same reason and condition as those in Embodiment <NUM> described above.

With the above-described configuration, information display device 1E and information display device 1E-<NUM> according to Embodiment <NUM> and the modification examples thereof can be disposed without causing the user to feel the position and the presence of display panel <NUM> through surface member <NUM>, and the information display with high designability can be realized. Furthermore, information display devices 1E and 1E-<NUM> can be replaced by detaching only display device <NUM> without peeling off the entire wall surface <NUM> (<FIG>) at the equipment failure. According to the configuration described in the embodiment, display device <NUM> can be detached from structural body <NUM> without damaging surface member <NUM>, and display device <NUM> can be brought into close contact with surface member <NUM> regardless of the surface state or material of surface member <NUM>. Further, a configuration in which the display region can be freely limited without processing surface member <NUM> or display panel <NUM> can be realized.

As illustrated in <FIG>, information display device 1F according to the embodiment is different from those in the above-described embodiments in that compressible cushion sheet <NUM> is disposed between touch panel <NUM> and surface member <NUM>. With the configuration, a void (air gap) hardly occurs between touch panel <NUM> and surface member <NUM>, and touch panel <NUM> can be reliably operated.

Information display device 1F is used in any usage environment similar to the above-described embodiments. The description of information display device 1F having the same configuration and function as those of the above-described embodiments will be omitted, and the same reference numerals will be given to the same configuration members.

<FIG> is a schematic sectional view of information display device 1F of the embodiment. Information display device 1F includes surface member <NUM>, cushion sheet <NUM>, touch panel <NUM>, display panel <NUM>, and housing <NUM>. Display panel <NUM> is disposed so as not to be seen through surface member <NUM>. The components that configure information display device 1F do not necessarily need to be assembled integrally. The components may be disposed apart from each other or may be configured to be easily separated from each other. For example, cushion sheet <NUM> may be configured to be easily detachable from other components. Accordingly, in a case where cushion sheet <NUM> needs to be replaced due to aging or the like, an effect that maintenance becomes easy is achieved.

The structural body <NUM> is an aluminum plate or the like for reinforcing surface member <NUM>. A case where surface member <NUM> has sufficient strength may not be necessary.

Cushion sheet <NUM> has the light transmitting properties, and is disposed between touch panel <NUM> and surface member <NUM> to be compressible. Since cushion sheet <NUM> is compressible, even in a case where surface member <NUM> has some unevenness, cushion sheet <NUM> can be disposed without forming a void between the front side of touch panel <NUM> and the back side of surface member <NUM>. In general, it is known that the sensitivity of touch panel <NUM> is extremely reduced by the air entering between the member disposed on the surface and touch panel <NUM> in touch panel <NUM> of a capacitive sensing method or a resistive membrane method. In the embodiment, the sensitivity of touch panel <NUM> can be reliably maintained by not forming a void between touch panel <NUM> and surface member <NUM>. In addition, cushion sheet <NUM> can prevent the video displayed on display panel <NUM> from being refracted due to the void and from being seen blur.

Cushion sheet <NUM> may be a member made of, for example, a gel material such as silicon, polyurethane, or urethane. Cushion sheet <NUM> may be plastically deformed by compression by an external force or may be elastically deformed by an external force. In particular, the positional relationship between surface member <NUM> and cushion sheet <NUM> may be displaced when display device <NUM> is subjected to some vibration or the position of fixing member <NUM> is displaced due to aging. Even in such a case, by using a material having elasticity as cushion sheet <NUM>, a void is hardly generated between the configuration components. Further, cushion sheet <NUM> can be easily reused.

Display device <NUM> is fixed to the back surface side of surface member <NUM> by fixing member <NUM>. In the embodiment, display device <NUM> is fixed by pressing housing <NUM> against surface member <NUM> side with fixing member <NUM>. However, the fixing method is an example, and any fixing method may be used as long as display device <NUM> can be fixed to the back surface side of surface member <NUM>.

<FIG> is an exploded sectional view of information display device 1F according to the embodiment. As illustrated in the drawing, in the embodiment, cushion sheet <NUM> has a larger area than touch panel <NUM> and is disposed so as to cover the entire touch surface. By making the surface area of cushion sheet <NUM> larger than the display surface of display panel <NUM> or the operation region of touch panel <NUM>, even in a case where there is a physical error in the position where cushion sheet <NUM> is pasted, the display surface of display panel <NUM> can be reliably operated. However, the configuration is not essential, and cushion sheet <NUM> may have the same area as that of touch panel <NUM> or may be disposed so as to cover a part of touch panel <NUM>.

In information display device 1F, by disposing surface member <NUM>, cushion sheet <NUM>, touch panel <NUM>, and display panel <NUM> in this order, a void between surface member <NUM> and touch panel <NUM> can be prevented, and the operation of touch panel <NUM> can be kept to be normal. In particular, there are a case where surface member <NUM> is a wall material and a case where there are some unevenness. In this case, a void is easily formed between surface member <NUM> and touch panel <NUM>. However, due to the presence of cushion sheet <NUM>, such a void can be effectively prevented, and the operability of touch panel <NUM> can be maintained.

<FIG> illustrates information display device 1F-<NUM> according to a modification example. As illustrated in the drawing, in information display device 1F-<NUM>, even in a case where surface member <NUM> is configured not in a flat shape but in a curved shape, cushion sheet <NUM> having a sufficient thickness is disposed, and accordingly, following surface member <NUM>, touch panel <NUM> can be reliably brought into an operable state.

<FIG> illustrates information display device 1F-<NUM> according to another modification example. As illustrated in the drawing, in information display device 1F-<NUM>, by disposing film <NUM> having an adhesive layer between surface member <NUM> and cushion sheet <NUM>, the generation of bubbles generated when cushion sheet <NUM> is in contact with surface member <NUM> is prevented. Accordingly, it is possible to prevent the generation of a void between touch panel <NUM> and surface member <NUM> and to make touch panel <NUM> more reliably operable. Furthermore, display device <NUM> can be easily separated from surface member <NUM>.

<FIG> is a schematic sectional view of information display device 1F-<NUM> according to the modification example. Information display device 1F-<NUM> includes surface member <NUM>, film <NUM>, cushion sheet <NUM>, touch panel <NUM>, display panel <NUM>, and housing <NUM>. Display panel <NUM> is disposed so as not to be seen through surface member <NUM>.

Information display device 1F-<NUM> is different from those of the above-described embodiments in that non-adhesive film <NUM> is disposed between surface member <NUM> and cushion sheet <NUM>. Film <NUM> is made of, for example, flame-retardant polycarbonate (PC) or polyether terephthalate (PET) or fluoropolymer having a thickness of approximately <NUM> to <NUM>. When the thickness of the film is extremely thick, there is a possibility that the elasticity of the film becomes too strong and it is not possible to follow the unevenness of the front surface of surface member <NUM>, and thus, a case where the thin film of the thickness is <NUM> or the like can expect more effect.

In non-adhesive film <NUM>, the surface of non-adhesive film <NUM> may be processed by cutting or finely cutting the most surface of the film. Accordingly, the processed surface of film <NUM> becomes easier to follow the unevenness of surface member <NUM>, and the generation of void therebetween can be prevented.

Embossing or Texture(extremely fine unevenness) may be provided on the back side (display panel <NUM> side) of surface member <NUM>. Accordingly, the effect of eliminating the adhesiveness of the back surface of surface member <NUM> and suppressing the generation of bubbles between surface member <NUM> and cushion sheet <NUM> can be expected.

In information display device 1F-<NUM>, by disposing non-adhesive film <NUM> between surface member <NUM> and cushion sheet <NUM>, when display device <NUM> including touch panel <NUM> breaks down, surface member <NUM> can be detached without breaking, only display device <NUM> can be easily detached from the wall surface, and accordingly, the maintenance work can become easy.

Instead of non-adhesive film <NUM>, a non-adhesive material is applied or painted to the front side and/or back side of cushion sheet <NUM>, or the front side and/or the back side of cushion sheet <NUM> are processed to have non-adhesiveness, and accordingly, a non-adhesive layer may be formed.

Otherwise, non-adhesive film <NUM> maybe slight-adhesive film or other slight adhesion layer.

<FIG> illustrates information display device 1F-<NUM> according to another modification example. As illustrated in the drawing, information display device 1F-<NUM> may include weakly adhesive film <NUM> on the back side (touch panel <NUM> side) of cushion sheet <NUM> in addition to the configuration illustrated in <FIG>. With the configuration, cushion sheet <NUM> can be peeled off from touch panel <NUM> again. Accordingly, even when cushion sheet <NUM> becomes dirty, torn, or deformed, only cushion sheet <NUM> can be detached from information display device 1F-<NUM> and replaced without breaking touch panel <NUM>. Thereby, the maintenance work can become easy.

Otherwise, weakly adhesive film <NUM> may be a non-adhesive film or another non-adhesive layer. The configuration can also make the maintenance work easy.

As illustrated in <FIG>, information display device <NUM> according to the embodiment performs a decoration process such as painting or printing on the front side and the back side of surface member <NUM> having the light transmitting properties, and accordingly, the adjustment of the light transmittance is possible without being affected by the pattern of the front surface of surface member <NUM>, and an information display device with excellent appearance can be realized.

Information display device <NUM> is used in any usage environment similar to the above-described embodiment. The description of information display device <NUM> having the same configuration and function as those of the above-described embodiments will be omitted, and the same reference numerals will be given to the same configuration members.

<FIG> is a schematic sectional view of information display device <NUM> of the embodiment. Information display device <NUM> includes surface member <NUM>, cushion sheet <NUM>, touch panel <NUM>, display panel <NUM>, and housing <NUM>. An effect that the replacement during the maintenance becomes easy as cushion sheet <NUM> can be peeled off from display device <NUM>. However the function as the information display device <NUM> can be satisfied without cushion sheet <NUM>.

Display device <NUM> is fixed to the back surface side of surface member <NUM> by fixing member <NUM>. In the embodiment, display device <NUM> is fixed by fixing housing <NUM> to the structural body <NUM> and pressing housing <NUM> against surface member <NUM> side with fixing member <NUM>. However, the fixing method is an example, and any fixing method may be used as long as display device <NUM> can be fixed to the back surface side of surface member <NUM>.

Surface member <NUM> includes first layer <NUM> subjected to the decoration process, plate-like member <NUM>, and second layer <NUM> for adjusting the light transmittance. First layer <NUM> and second layer <NUM> are formed by decorating the front side and the back side of plate-like member <NUM> by painting or printing. For example, in the usage environment illustrated in <FIG>, first layer <NUM>, which is the front surface side directly seen from user <NUM>, is decorated more precisely, such as printing or painting, which imitates a real material. However, when such decoration is performed, it becomes difficult to control the light transmittance and displayed information on surface member <NUM> may blurred. Therefore, the side which is not directly visible from user <NUM>, that is, the back side of surface member <NUM> is also decorated by painting or printing. By providing the decorated layers on both surfaces in this manner, the blur and the light transmittance passing through surface member <NUM> and decorated first layer <NUM> and second layer can be controlled with a high degree of freedom. For example, in a case where a light-colored wood pattern is printed on first layer <NUM> on the front surface side of surface member <NUM>, the amount of light transmitted from the front surface side of the first layer to display device <NUM> side increases, and there is a possibility that the shape of display panel <NUM> is seen from the user. Here, by painting second layer <NUM> on the back side of surface member <NUM> with a relatively dark color ink, the amount of transmitted light can be adjusted to prevent display panel <NUM> from being seen through surface member <NUM>. Further, since surface member <NUM> is a transparent or translucent material, by decorating both surfaces of surface member <NUM>, the decorative expression seen from the front surface side can be deepened, and the authenticity can be further enhanced. On the other hand, when there is a distance between the surface member <NUM> and the display <NUM> as shown in <FIG>, the information displayed on the surface of the surface member <NUM> is blurred. Therefore, an optical filter having a characteristic of transmitting light rays of high luminance and blocking light rays of low luminance is provided as the second layer <NUM>. As a result, as shown in <FIG>, only light in the vertical direction with respect to the display <NUM> having relatively high brightness reaches the surface member <NUM>, and light emitted in other directions does not reach the surface member <NUM>. Thereby, the blurring of the information displayed on the surface member <NUM> can be suppressed.

First layer <NUM> and/or second layer <NUM> may be made of a film.

Second layer <NUM> having a light transmittance adjusting function may be formed by vapor deposition. Otherwise, the second layer may be formed by translucent solid printing. In this case, the printing may be performed by performing painting with black with a light transmittance of <NUM>% to <NUM>%.

First layer <NUM> is disposed to be in close contact with a part or the entirety of the front side of plate-like member <NUM>, and second layer <NUM> is disposed to be in close contact with a part or the entirety of the back side of plate-like member <NUM>.

The light transmittance of second layer <NUM> is preferably <NUM>% to <NUM>%. Otherwise, second layer <NUM> may be formed by a half mirror having a light transmittance of <NUM>% to <NUM>%. Alternatively, second layer <NUM> may be formed by an optical filter. In this case, for example, the optical filter is designed to transmit only light from display panel <NUM> and prevent transmission of external light. Alternatively, it is preferable that the optical filter has a characteristic of transmitting only the light having a luminance of <NUM> cd / m ^ <NUM> or more among the light arriving from the display panel <NUM> and blocking the light having a luminance less than that.

The combined light transmittance of first layer <NUM> and second layer <NUM> is preferably <NUM>% to <NUM>%.

The same effect can be realized even if the second layer <NUM> is disposed on the surface of the touch panel <NUM> (specifically, the surface of the cover glass of the touch panel) instead of the surface of the plate-like member <NUM>. When the second layer <NUM> is installed on the touch panel side, the plate-like member <NUM> needs only the first layer <NUM> to decorate the surface, and the surface treatment applied to the plate-like member <NUM> can be reduced. The choice of materials used for the layer <NUM> can be expanded. Display panel <NUM> is preferably adjusted by CPU <NUM> (<FIG>) such that the luminance on surface member <NUM> due to the light transmitted through surface member <NUM> is <NUM> cd/m^<NUM> or less. Preferably, display panel <NUM> is adjusted by CPU <NUM> (<FIG>) such that the luminance of the light source (not illustrated) at the time of being turned on is <NUM> cd/m^<NUM> or more.

With the above-described configuration, information display device <NUM> adjusts the amount of light transmission of surface member <NUM> to prevent display panel <NUM> from being seen through surface member <NUM>, and to make the information displayed on surface member <NUM> comfortably seen from the user.

<FIG> illustrates information display device <NUM>-<NUM> according to a modification example. In the example illustrated in <FIG>, the decorative layers are provided on the front side and the back side of surface member <NUM>, but the method of realizing surface member <NUM> is not limited thereto. For example, the surface member is formed by decorative film <NUM> having the light transmitting properties disposed on the surface of a transparent plate having a sufficient rigidity, and the same effect can be obtained by performing the decoration process with respect to the both surfaces of decorative film <NUM>.

<FIG> is a schematic sectional view of information display device <NUM>-<NUM>. Information display device <NUM>-<NUM> includes decorative film <NUM> that is a transparent or translucent film member, light-transmitting plate <NUM> that is a plate-like member, cushion sheet <NUM>, touch panel <NUM>, display panel <NUM>, and housing <NUM>. Surface member <NUM> includes light-transmitting plate <NUM> for maintaining rigidity and decorative film <NUM> for realizing surface decoration. Decorative film <NUM> includes first layer <NUM> and second layer <NUM>. The decoration process is performed on the front side of decorative film <NUM> to form first layer <NUM>, and the decoration process is performed on the back side of decorative film <NUM> to form second layer <NUM>.

First layer <NUM> is disposed to be in close contact with a part or the entirety of the front side of decorative film <NUM>. Second layer <NUM> is disposed to be in close contact with a part or the entirety of the back side of decorative film <NUM>. Decorative film <NUM> may be pasted to light-transmitting plate <NUM> with an adhesive.

With the above-described configuration, information display device <NUM>-<NUM> can control the light transmittance and express the depth to the decorative expression, similar to the example illustrated in <FIG>.

In the usage environment in the embodiment, information display device <NUM> is disposed on wall surface <NUM> in an aircraft or the like. Information display device <NUM> displays information displayed on the display panel to be seen on display region 1a by transmitting the light of the display panel from the back side of surface member <NUM>.

Information display device <NUM> according to the embodiment is different from those in the above-described embodiments mainly in that reflectance variable reflection layer (half mirror layer) <NUM> capable of partially changing the light transmittance and the reflectance is provided. Normally, by adding a reflection layer between surface member <NUM> and display panel <NUM> of the information display device, appearance of transparency on the surface decoration layer of surface member <NUM> can be reduced, and the images on display region 1a can also be colored with an appropriate color. However, the reflection layer also reduces the light from the light source (display panel <NUM> or another light source) inside display device <NUM>. For example, when the reflectance of the reflection layer is <NUM>%, the light transmittance is also <NUM>%. Therefore, the light from display panel <NUM> to be displayed becomes darker, and the place not to be displayed becomes bright and prominent. For example, in a case where a liquid crystal display is used, there is a case where the light of the backlight is visible even on a dark screen.

In the embodiment, a reflection layer of which the light transmittance or the reflectance can be partially changed is provided. In the reflection layer, the light transmittance of only the location desired to be displayed from display panel <NUM> is increased, the light transmittance of the other locations (the locations where information is not displayed) is reduced to increase the reflectance, and accordingly, an information display device of which the real feeling of the decorative layer on surface member <NUM> is improved can be realized.

In addition, by increasing the light transmittance and lowering the reflectance for a certain region of the display, there is a case where the color of the background is different from the intended color of the surface decoration layer, and the color of the background is picked up and darkened, but at this time, display panel <NUM> emits light that corrects the amount of darkness caused by the increase in the transparency of the reflection layer with respect to the surface decoration layer, and accordingly, the unnaturalness can be eliminated.

Although display region 1a in which the light transmittance can be changed is expressed by a square in <FIG>, the shape, the number, and the size of display region 1a are not limited.

<FIG> is a configuration view of a system for operating information display device <NUM> according to the embodiment. CPU <NUM> causes display panel <NUM> to display necessary or useful information for user <NUM> based on the information from in-flight server <NUM>. CPU <NUM> determines a region where the reflectance or the light transmittance of reflectance variable reflection layer <NUM> is changed based on the information to be displayed on display panel <NUM> and the ambient light information from ambient light sensor <NUM>, which are acquired from in-flight server <NUM>. CPU <NUM> also calculates the reflectance and/or the light transmittance based on the ambient light information from ambient light sensor <NUM>, and changes the reflectance or the light transmittance of reflectance variable reflection layer <NUM>. In addition, in a case where ambient conditions can be grasped without measuring, or in a case where ambient light conditions may not be considered, an ambient light sensor may not be provided. In this case, CPU <NUM> controls reflectance variable reflection layer <NUM> based on predetermined reference information (for example, the luminance of display panel <NUM>).

<FIG> is a schematic sectional view of information display device <NUM> of the embodiment. Information display device <NUM> includes surface member <NUM>, reflectance variable reflection layer (half mirror) <NUM>, and display panel <NUM>. Light from display panel <NUM> is transmitted through reflectance variable reflection layer <NUM> and displays information on display region 1a of surface member <NUM>.

Information display device <NUM> according to the embodiment can enhance the effect of decoration such as a real feeling other than the location on surface member <NUM> where information is displayed, and can improve the light transmittance of the location where information is displayed on display panel <NUM>.

<FIG> illustrates a usage environment of information display device 1I according to the embodiment.

In the usage environment in the embodiment, information display device 1I is disposed on wall surface <NUM> in an aircraft or the like. Information display device <NUM> performs display such that user <NUM> can see the display in display region 1a by transmitting the light of the display panel from the back side of surface member <NUM>.

Information display device 1I is used in any usage environment similar to the above-described embodiment. The description of information display device 1I having the same configuration and function as those of the above-described embodiments will be omitted, and the same reference numerals will be given to the same configuration members.

Information display device 1I is different from those of the above-described embodiment in that reflection layer (half mirror layer) <NUM> that can selectively transmit the light from display panel <NUM> is provided. With such a configuration, the light from display panel <NUM> can be selectively transmitted. Reflection layer <NUM> transmits only light desired to be displayed from display panel <NUM>, does not transmit other light, and accordingly, it is possible to prevent unnecessary display and light leakage, and to enhance the real feeling of the surface decoration layer of surface member <NUM>.

<FIG> is a configuration view of a system for operating information display device 1I according to the embodiment. CPU <NUM> calculates the wavelength of light that is easily transmitted through reflection layer <NUM> based on information from in-flight server <NUM>, and causes display panel <NUM> to display the light. Reflection layer <NUM> that can selectively transmit the light may have a role of a filter that converts the wavelength of the light and transmits the light. By doing so, it is considered that the expression of colors with better color development becomes possible.

<FIG> is a schematic sectional view of information display device 1I of the embodiment. Information display device 1I includes surface member <NUM>, reflection layer (half mirror) <NUM> for selectively transmitting light, and display panel <NUM>, the light from display panel <NUM> is transmitted through reflection layer <NUM>, and the information is presented to the user through display region 1a on surface member <NUM>.

With the above-described configuration and operation, information display device 1I of the embodiment has an effect of reducing elements that deteriorate the real feeling at locations other than the locations where information is displayed by the light of the backlight of display panel <NUM> or the like. Furthermore, a location to be displayed on display panel <NUM> can be clearly displayed.

<FIG> illustrates a usage environment of information display device 1J according to the embodiment.

In the usage environment in the embodiment, information display device 1J is disposed on partition <NUM> which is a part of the interior of the aircraft. Partition <NUM> partitions a space in the aircraft, such as a wall that separates the personal space of passengers from a passage where crews walk, and a wall of a shell seat. Partition <NUM> has surface 41a and surface 41b opposite to surface 41a. Information display device 1J according to the embodiment is different from those of the above-described embodiments mainly in that information display device 1J is disposed so as to provide display regions 1a and 1b on both surfaces of partition <NUM>.

Information display device 1J is used in any usage environment similar to those of the above-described embodiments as long as information display device 1J is a plate-like structure such as partition <NUM> and has a structure that is open on both sides. For example, the structure is disposed on a wall, a door of a container, or a seat disposed in an aircraft, that is, at a position visible from a passenger or a crew of the moving object. As illustrated in the example illustrated in <FIG>, information display device 1J may be disposed on wall surface <NUM> of the cabin wall of the seat compartment, the information mainly toward crew <NUM> such as a cabin crew may be displayed on the display surface on the passage side of the wall surface <NUM>, and the information toward the passenger may be displayed on the display surface on the seat side opposite to the wall surface <NUM>. The description of information display device 1J having the same configuration and function as those of the above-described embodiments will be omitted, and the same reference numerals will be given to the same configuration members.

As illustrated in <FIG>, information display device 1J is installed in partition <NUM> of which the upper part is curved. As illustrated in the exploded perspective view of <FIG>, structural body <NUM> that serves as the basis of partition <NUM> is a plate-like structure having a curved upper part, recess 410a is formed by depressing a part of the upper part, and plate-like body <NUM> is formed on recess 410a. Display panel <NUM> is attached to be over plate-like body <NUM> in recess 410a. Surface member <NUM> is attached so as to cover display panel <NUM> and structural body <NUM>.

<FIG> is a schematic sectional view of information display device 1J. Information display device 1J includes plate-like body <NUM> which is a part of structural body <NUM>, display panel <NUM>, and surface member <NUM>. Plate-like body <NUM> has first attaching surface 43a, second attaching surface 43b opposite to first attaching surface 43a, and side portion 43c that connects first attaching surface 43a and second attaching surface 43b to each other.

Display panel <NUM> is, for example, an OLED(Organic Light Emitting Diode) display or the like, and is a flexible display device that can be bent. Display panel <NUM> has first display surface 23a via curved portion 23c, and second display surface 23b opposite to first display surface 23a. Display panel <NUM> is attached onto plate-like body <NUM> such that first display surface 23a covers first attaching surface 43a, second display surface 23b covers second attaching surface 43b, and curved portion 23c covers side portion 43c. Display panel <NUM> can display different information on first display surface 23a and second display surface 23b.

Display panel <NUM> disposed on plate-like body <NUM> in recess 410a may have a thickness that does not protrude to the outside of recess 410a, that is, does not protrude from the outer surface of the other parts of structural body <NUM>. In other words, the vertical and horizontal length and thickness of display panel <NUM> are configured to substantially match the vertical and horizontal length and depth of recess 410a. Accordingly, the surface of structural body <NUM> other than the part where recess 410a is formed can be substantially flush with the display surface of display panel <NUM>.

Surface member <NUM> has a surface area larger than that of display panel <NUM>, and is pasted so as to cover recess 410a to which display panel <NUM> is attached and the other parts of structural body <NUM>.

Information display device 1J according to the embodiment has high designability by realizing information display in a seamless region having no boundary with a wall surface, and additionally, can perform various information presentations efficiently by disposing the display regions on both sides of the wall. Furthermore, since the information is displayed on both sides of the wall with one information display device, the number of components and the complexity of wiring can be reduced.

In the above embodiment, as shown in <FIG> and <FIG>, the upper portion of the side portion 43c of the plate-like body <NUM> has a approximately right-angled shape. Instead of this right-angled shape, it may be the curved shape along with the curved portion 23c of the display panel <NUM> (or It maybe a rounded shape on the corners). Thereby, the load generated when the display panel <NUM> is attached can be reduced.

Between display panel <NUM> and surface member <NUM>, a transparent or translucent member (not illustrated) disposed to cover the display surface of display panel <NUM> may be disposed.

The transparent or translucent member is, for example, a laminated film. The laminated film has such characteristics that, while having the light transmitting properties, the presence of the internal configuration (display panel <NUM> or recess 410a) on the back side of surface member <NUM> is not visible when viewed from the line of sight of user <NUM> (<FIG>). The laminated film is pasted with an adhesive or the like so as to cover structural body <NUM> and display panel <NUM> before surface member <NUM> is disposed. With the configuration, light emitted from display panel <NUM> can be projected on surface member <NUM> through the laminated film. Accordingly, when the information is not displayed, only the information displayed in a region that is not different from the surrounding wall surface can be made to emerge, and accordingly, extremely high designability can be realized.

Since the outer surface of the other parts of structural body <NUM> other than recess 410a and the display surface of display panel <NUM> are substantially flat, the operation of pasting the laminated film becomes easy. Accordingly, the steps required for manufacturing information display device 1J become simple. Further, the laminated film is sufficient when the film has a certain degree of light transmitting properties and does not require any special characteristics, and thus, a film generally used as a building material can be used. For example, even in an environment with strict fire prevention standards such as in an aircraft, wallpaper that has already been used in such an environment can often be used as it is.

The transparent or translucent member may be provided only on display panel <NUM> in recess 410a. In this case, the transparent or translucent member is attached such that the front surface is flush with, or at least protrudes from, the outer surface of the other parts of structural body <NUM> other than recess 410a. In other words, the depth of recess 410a is a size obtained by adding the thickness of display panel <NUM> and the thickness of the transparent or translucent member.

Partition <NUM> may not have the upper curved portion. For example, as illustrated in <FIG>, structural body <NUM> which is the basis of partition <NUM> has a rectangular upper portion. In structural body <NUM>, recess 410a is formed by depressing a part of the upper portion similar to the example illustrated in <FIG>, and plate-like body <NUM> is formed in recess 410a. As illustrated in <FIG>, display panel <NUM> is attached to be over plate-like body <NUM> in recess 410a. Display panel <NUM> is bent and disposed in a rectangular shape according to the shape of the upper portion of structural body <NUM> in which recess 410a is formed. As illustrated in <FIG>, surface member <NUM> is attached so as to cover display panel <NUM> and structural body <NUM>.

In addition, similar to the above-described example, the vertical and horizontal length and thickness of display panel <NUM> are configured to substantially match the vertical and horizontal length and depth of recess 410a. Further, display panel <NUM> may be formed to have a thickness that does not protrude from the outside of recess 410a, that is, does not protrude from the outer surface of the other parts of structural body <NUM>. Similar to the above-described example, between display panel <NUM> and surface member <NUM>, a transparent or translucent member (not illustrated) disposed to cover at least the display surface of display panel <NUM> may be disposed.

In the above embodiment, as shown in <FIG>. the side portion 43c of the plate body <NUM> may be formed in a curved shape (or a rounded shape on the corners). With such a configuration, even if the upper portion of the display panel <NUM> has a right-angled shape, the load generated when the display panel <NUM> is attached can be reduced.

The surface member <NUM> does not have to be arranged on both sides of the structure <NUM>. For example, the front surface member <NUM> may be arranged on each of the front and back surfaces, the side surfaces, and the top surface of the structure <NUM> such as a wall. In that case, the surface member <NUM> on each surface of the structure <NUM> may be made of different materials. For example, a part or all of the surface member <NUM> that covers the first mounting surface 43a, the surface member <NUM> that covers the second mounting surface 43b, and the surface member <NUM> that covers the side portion 43c of the plate body <NUM> are made of different materials or patterns.

Similar to the example illustrated in <FIG>, information display devices <NUM> to 1J include touch panel <NUM>, CPU <NUM>, and display panel <NUM>. CPU <NUM> selects information to be presented to user <NUM> (<FIG>) based on information from the in-flight server, and displays optimal information.

According to the above-described operation, in the embodiment, it becomes possible to realize an information display device that can provide information optimal for the user in accordance with the in-flight conditions without damaging the sense of luxury.

In the embodiment, a case where the in-flight conditions are acquired from the in-flight server is employed as an example, but the in-flight conditions may be determined by CPU <NUM> from a clock built in the information display device, a sensor that detects inclination or vibration, and the like. Further, in a case where there are a plurality of information display devices in the cabin, an optimal information display device may be selected in accordance with the in-flight conditions. For example, when the passenger is eating, an information display device at a position that can be easily seen from the dining table may be selected to display the information.

(<NUM>)
Information display devices <NUM> to 1J may determine the information from the in-flight environment sensor and change the contents to be displayed based on the in-flight environment (temperature, humidity, illuminance, air pressure, and the like). Since the information is displayed on the wall surface, it is possible to realize an information display device which can perform display without damaging the sense of luxury even when the display contents and the display amount are changed and the region that is not displayed is changed.

Similar to the example illustrated in <FIG>, information display devices <NUM> to 1J include touch panel <NUM>, CPU <NUM>, and display panel <NUM>. CPU <NUM> selects information to be presented to user <NUM> (<FIG>) based on information from the plurality of sensors (not illustrated) which are disposed in the cabin, and displays optimal information. For example, a button for requesting a blanket is displayed when the temperature drops. Accordingly, it is possible to select information to be presented to user <NUM> (<FIG>), and to display optimal information.

According to the above-described operation, in the embodiment, it becomes possible to realize an information display device that can provide information optimal for the user in accordance with the in-flight environment without damaging the sense of luxury.

In the embodiment, a case where the in-flight environment is acquired from the in-flight environment sensor is employed as an example, but the in-flight environment may be determined from a clock or the like built in the in-flight server or the information display device. Further, in a case where there are a plurality of information display devices in the cabin, an optimal information display device may be selected in accordance with the in-flight conditions.

(<NUM>)
<FIG> illustrates a usage aspect of information display device <NUM> according to the embodiment.

In the usage environment in the embodiment, information display device <NUM> is disposed on wall surface <NUM> which is a part of the interior of the aircraft. Information display device <NUM> transmits the light of the display panel from the back side of surface member <NUM> and displays information in display region 1a on surface member <NUM> such that user <NUM> can be seen. Information display device <NUM> is characterized in that a film having a designability and light transmitting properties is pasted to the front of the display device, and that the pattern of the film having a designability is the same pattern as that of the wall surface around the display device.

<FIG> is a schematic sectional view of information display device <NUM> of the embodiment. Information display device <NUM> includes surface member 11a, reflection member (half mirror) <NUM>, structural body <NUM>, touch panel <NUM>, display panel <NUM>, wall surface member 11b, and void <NUM>. Void <NUM> is formed between surface member 11a and wall surface member 11b, and is formed so as to surround the outer edge of display panel <NUM>. The front side of surface member 11a and the front side of wall surface member 11b are decorated with the same pattern. As illustrated in <FIG>, surface member 11a and reflection member <NUM> are disposed on the bottom surface of void <NUM>. Accordingly, the boundary between wall surface member 11b and surface member 11a can be made prominent. The member to be pasted to the bottom surface of void <NUM> may be wall surface member 11b.

In order to realize an information display device in which display region 1a and other parts can be seen seamlessly, it is preferable that void <NUM> is not present. However, by providing void <NUM>, during the maintenance, only surface member 11a can be detached from wall surface <NUM> and only display panel <NUM> or touch panel <NUM> can be picked up.

It is preferable that void <NUM> has a width that does not hinder removal. For example, when the void has a width of approximately <NUM> to <NUM>, it is considered that both aesthetic appearance and practicality can be achieved.

With the above-described configuration, information display device <NUM> according to the embodiment does not allow user <NUM> to feel the position and the presence of display panel <NUM>, can detach and replace only the display panel <NUM> without peeling off the entire wall in the event of a failure. Accordingly, information display device <NUM> can make the maintenance simple while realizing a seamless design in which the joints are not visually prominent.

(<NUM>)
In the above-described embodiment, the surface member <NUM> may include a transparent member, even if not particularly described. In this case, the transparent member may have same configuration and function as the transparent member <NUM> of the third embodiment and the like.

(<NUM>)
In the above-described embodiment, a part or the entirety of processing of each functional block may be realized by a program. A part or the entirety of processing of each functional block may be executed by a processor in a computer. A program for performing each processing may be stored in a storage device such as a hard disk or a ROM, and may be read and executed on the ROM or the RAM.

In the above-described embodiment, a processor formed by a dedicated electronic circuit designed to realize a predetermined function may be included instead of the CPU. Further, instead of the CPU, the functions may be realized by various processors such as an MPU, a GPU, a DSP, an FPGA, and an ASIC. The processor may be formed by one or more processors.

In the above-described embodiment, an example has been described in which information display devices <NUM> to 1J are installed in the aircraft. However, the disclosure is not limited thereto. The location where information display devices <NUM> to 1J are installed may be other moving objects or vehicles such as trains, buses, ships, and the like.
