Patent Description:
Recently, with the expansion of smart interactive functions, display devices that provide user interactions have appeared. The user interaction is typically used to control the display device with user's motion or voice. Accordingly, a photographing unit for sensing user's motion or a voice sensing unit for sensing user's voice is sometimes mounted on the display device.

The photographing unit or the voice sensing unit is often fixedly mounted at an upper end of a display device in the related art. According to such a display device, however, the upper end portion thereof always projects outward due to the mount of the photographing unit or the voice sensing unit, and this spoils the beauty of the display device. Further, due to the exposed photographing unit or voice sensing unit, a user may feel like the user is always being watched, and this may give the user an unpleasant feeling.

To attempt to solve this problem, the photographing unit and the voice sensing unit may be silidably mounted on an upper portion of the rear surface of the display device to slide upward and downward so that the photographing unit and the voice sensing unit are unable to be seen by the user when they are not in use. For example, the photographing unit may project upward from the upper portion of the rear surface of the display device during photographing, and the projecting photographing unit may slide downward and may not be seen from the front of the display device during non-photographing. The photographing unit and the voice sensing unit as described above are positioned behind the display device as far as the thickness of the side portion of the display device from the front surface of the display device. Accordingly, in order to secure a large camera viewing angle, it is required to make the photographing unit project further upward, and this may spoil the beauty of the display device.

<CIT> discloses a hidden image capturing device is applied to a display. The hidden image capturing device has a shell, a control module, a slide module, and an image capturing module. The slide module is disposed in the shell and controlled by the control module for sliding.

Additional aspects and/or advantages will be set forth in part in the description which follows and, in part, will be apparent from the description, or may be learned by practice of the embodiments.

Accordingly, an aspect of the present disclosure provides a display apparatus that can secure a large camera viewing angle without spoiling the beauty of the display apparatus.

According to an aspect of the present invention, there is provided a display apparatus as set out in claim <NUM>.

The above and other aspects, features and advantages of the present disclosure will be more apparent from the following detailed description when taken in conjunction with the accompanying drawings, in which:.

In this embodiment, the display main body <NUM> includes a main casing <NUM>, a display panel (not illustrated), a control board (not illustrated), a power board (not illustrated), and an auxiliary casing <NUM>.

The main casing <NUM> accommodates various kinds of components of the display apparatus <NUM>, such as the display panel (not illustrated), the control board (not illustrated), and the power board (not illustrated).

The display panel is a component that displays an image, and has an image display surface <NUM>. A user may view various pieces of content provided from the display apparatus <NUM> through the image display surface <NUM>.

In this embodiment, the control board is to control the operation of the display apparatus <NUM>, and may control the operation of the display apparatus <NUM> in accordance with a command according to the user interaction. The power board is to supply a voltage to the display apparatus <NUM>.

The auxiliary casing <NUM> is mounted on an upper portion of the rear surface of the main casing <NUM> as described above, and accommodates the photographing unit <NUM>. In this embodiment, the auxiliary casing <NUM> is separately mounted on the rear surface of the main casing <NUM>, and it is also possible to form the auxiliary casing <NUM> in a body with the main casing <NUM>. Although it is possible to mount the casing <NUM> on a bottom portion of the rear surface of the main casing <NUM> or on a side of the main casing <NUM>, in other embodiments.

Referring to <FIG> and <FIG>, the auxiliary casing <NUM> includes a front casing <NUM> and a rear casing <NUM>.

The front casing <NUM> is engaged with the upper portion of the rear surface of the main casing <NUM>. The front casing <NUM> has an opening <NUM> on an upper surface thereof <NUM>, through which the photographing unit <NUM> passes or extends. Through the opening <NUM>, the photographing unit <NUM> projects out of the auxiliary casing <NUM> or is accommodated in the auxiliary casing <NUM>.

The rear casing <NUM> is engaged with the front casing <NUM> to form the rear surface of the auxiliary casing <NUM> or be flush with a top surface of casing <NUM>. In a space between the front casing <NUM> and the rear casing <NUM>, various kinds of components for user interactions of the display apparatus <NUM>, such as the photographing unit <NUM> and the voice sensing unit <NUM>, are accommodated.

In some embodiments, the photographing unit <NUM> is arranged to sense user's gestures, and is slidably mounted on the auxiliary casing <NUM>. During non-photographing, the photographing unit <NUM> is accommodated in the auxiliary casing <NUM> and is arranged so as not to exceed the height of the auxiliary casing <NUM>. When the photographing unit <NUM> is accommodated in the auxiliary casing <NUM>, a protection window <NUM> is arranged at the same height as the height of the upper surface <NUM> of the main casing <NUM>. In other embodiments, the photographing unit <NUM> is provided for other purposes, such as for capturing still or moving images of the user.

Referring to <FIG>, the photographing unit <NUM> includes a camera casing <NUM>, a camera module <NUM>, and a tilt lever <NUM>.

The camera casing <NUM> includes a base casing <NUM> and a cover casing <NUM>.

In the base casing <NUM>, the camera module <NUM> and the tilt lever <NUM> are mounted, and the protection window <NUM> is mounted on the front surface thereof. The base casing <NUM> may be made of an aluminum material to dissipate heat generated from the camera module <NUM>.

The cover casing <NUM> is engaged with the base casing <NUM> to form an external appearance of the photographing unit <NUM>. As illustrated in <FIG>, on the cover casing <NUM>, a front opening <NUM> into which the protection window <NUM> is inserted and a tilt lever opening <NUM> for exposing the tilt lever <NUM> are formed. On the other hand, unlike the base casing <NUM>, the cover casing <NUM> may be made of a plastic material.

In this embodiment, the camera module <NUM> is a constituent element provided in the photographing unit <NUM> to sense the user's gestures. The photographing unit <NUM> has the built-in camera module <NUM> to sense the user's gestures. The camera module <NUM> includes at least one lens (not illustrated) collecting light of the image, an image sensor (not illustrated) converting the image into an electrical signal, and an actuator (not illustrated) configured to adjust a focus through movement of the lens.

As illustrated in <FIG> and <FIG>, the photographing unit <NUM> is arranged at the first position that is accommodated in the auxiliary casing <NUM> during the non-photographing or no-image capturing. The photographing unit <NUM> is arranged to be spaced apart from the image display surface as far as the thickness d of the main casing <NUM> from the image display surface <NUM>. That is, the distance d between the photographing unit <NUM> and the image display surface <NUM> may be substantially the same as the thickness d of the main casing <NUM>. In this case, the camera module <NUM> is arranged to look toward an upper direction (+Z direction). Through this, during the non-photographing, the photographing unit <NUM> of this embodiment is hidden as seen from the front of the display apparatus <NUM>. Accordingly, user inconvenience that a user may feel due to the projecting photographing unit <NUM> can be solved. Further, during the non-photographing, the external appearance of the display apparatus <NUM> is neat and tidy, and thus an advanced image of the product can be sought.

As illustrated in <FIG> and <FIG>, during user's photographing, the photographing unit <NUM> is arranged at the second position or image-capture position where the photographing unit <NUM> projects out of the auxiliary casing <NUM>. The photographing unit <NUM> projects in the front direction (+X direction) of the display apparatus <NUM> toward a view position at which a user would view the display and is arranged on the upper surface <NUM> of the main casing <NUM>. In this case, the photographing unit <NUM> is arranged to be spaced apart for a predetermined distance d' from the image display surface <NUM>, and the protection window <NUM> of the photographing unit <NUM> is arranged somewhat behind the image display surface <NUM>. That is, the distance d' between the photographing unit <NUM> and the image display surface <NUM> is shorter than the thickness d of the main casing <NUM> so that the main casing <NUM> does not block the camera view as depicted in <FIG>. As compared with the first position (the position where the photographing unit <NUM> is accommodated in the auxiliary casing <NUM>) as described above, the photographing unit <NUM> is arranged closer to the image display surface <NUM> when the photographing unit <NUM> is at the second position rather than at the first position. Accordingly, during photographing, it is not necessary for the photographing unit <NUM> to additionally project in the upper direction (+Z direction) of the display apparatus <NUM> in order to secure a large camera and unblocked viewing angle. In other words, the display apparatus <NUM> of this embodiment can secure a large camera viewing angle without spoiling the beauty of the display apparatus <NUM>.

The tilt lever <NUM> is a constituent element for adjusting a tilt of a camera. The term "tilt" in this context refers to photographing in a state where the position of the camera is fixed and only an angle is changed from top to bottom or from bottom to top. In accordance with an operation of the tilt lever <NUM>, the camera module <NUM> is rotated up and down around the Y-axis direction. The tilt lever <NUM> is exposed to an outside through the tilt lever opening <NUM> of the cover casing <NUM>. A user may adjust the tilt of the camera as much as desired through the operation of the tilt lever <NUM>.

<FIG> is a view illustrating an interior of the auxiliary casing of <FIG>.

Referring to <FIG> and <FIG>, the display apparatus <NUM> further includes a voice sensing unit <NUM> and a PCB board <NUM>.

The voice sensing unit <NUM> is mounted to be accommodated in the auxiliary casing <NUM>, and is not exposed out of the auxiliary casing <NUM>. In the display apparatus <NUM> according to this embodiment, since the voice sensing unit <NUM> is not integrally provided with the photographing unit <NUM>, but is provided separately from the photographing unit <NUM>, it is not necessary to provide an additional space for the voice sensing unit <NUM> in the photographing unit <NUM>. Accordingly, the volume of the photographing unit <NUM> that is exposed to the outside can be reduced in the display apparatus <NUM> according to this embodiment.

The voice sensing unit <NUM> includes a microphone <NUM> and a microphone hole <NUM>.

The microphone <NUM> is a constituent element for sensing user's voice. One or more microphones <NUM> may be provided, and in this embodiment, two microphones <NUM> are provided. The two microphones <NUM> are provided on both sides of the photographing unit <NUM>, and are arranged adjacent to the upper surface <NUM> of the front casing <NUM>. The microphone hole <NUM> guides transfer of the user's voice to the microphone <NUM>. In this embodiment, four microphone holes <NUM> are provided. Specifically, two microphone holes <NUM> are provided on the rear casing <NUM> to face the rear surface of the microphone <NUM>.

The PCB board <NUM> determines the user interaction based on user's gesture information sensed by the photographing unit <NUM> and user's voice information sensed by the voice sensing unit <NUM>. The PCB board <NUM> transmits information on the user interaction to the control board (not illustrated) of the display apparatus <NUM>, and the control board (not illustrated) of the display apparatus <NUM> controls the display apparatus <NUM> based on the information on the user interaction.

On the other hand, the PCB board <NUM> may not determine the user interaction based on the user's gesture information sensed by the photographing unit <NUM> and the user's voice information sensed by the voice sensing unit <NUM>, but may transmit the user's gesture information sensed by the photographing unit <NUM> and the user's voice information sensed by the voice sensing unit <NUM> directly to the control board of the display apparatus. In this case, the control board of the display apparatus <NUM> may determine the user interaction based on the user's gesture information sensed by the photographing unit <NUM> and the user's voice information sensed by the voice sensing unit <NUM>, and then may control the display apparatus accordingly.

Referring to <FIG> and <FIG>, the display apparatus <NUM> further includes a locking unit <NUM>, a slider <NUM>, a guide rail <NUM>, an elastic member <NUM>, and a damping member <NUM> so that the photographing unit <NUM> becomes movable between the first position (the position where the photographing unit <NUM> is accommodated in the auxiliary casing <NUM>) and the second position (the position where the photographing unit <NUM> projects out of the auxiliary casing <NUM>).

The locking unit <NUM> is a constituent element for locking the photographing unit <NUM> that is arranged at the first position in the auxiliary casing <NUM>. The locking unit <NUM> releases the locking if the photographing unit <NUM> is arranged at the second position.

The locking unit <NUM> includes a latch unit <NUM> and a locking member <NUM>.

The latch unit <NUM> is mounted on the slider <NUM>, and the slider <NUM> is engaged with the photographing unit <NUM>. Accordingly, the latch unit <NUM> is connected to the photographing unit <NUM> through the slider <NUM>. The latch unit <NUM> is engaged with the locking member <NUM> and is separated from the locking member <NUM> to lock and unlock the photographing unit <NUM>.

The latch unit <NUM> includes a latch housing <NUM> and a hook member <NUM>.

The latch housing <NUM> is mounted on the slider <NUM>. A spring (not illustrated) that pushes the hook member <NUM> out of the latch housing <NUM> when the locking is released is built in the latch housing <NUM>. A pair of hook members <NUM> are provided and mounted on the latch housing <NUM> to be movable between an exposure position for being exposed out of the latch housing <NUM> and a partial insertion position for being partially inserted into the latch housing <NUM>.

The locking member <NUM> is provided on the rear casing <NUM> of the auxiliary casing <NUM>. The locking member <NUM> is formed to project from the lower surface of the inner side of the rear casing <NUM> in the upper direction (+Z direction). The locking member <NUM> is integrally formed with the rear casing <NUM>, but is not limited thereto. It is also possible that the locking member <NUM> is provided as a separate member and is mounted on the rear casing.

The locking member <NUM> includes a body portion <NUM> and an engagement portion <NUM>.

The body portion <NUM> is formed to extend from the rear casing <NUM> in the vertical direction (+Z direction). The engagement portion <NUM> is provided at the front end of the body portion <NUM>, and is detachably engaged with the hook member <NUM> of the latch unit <NUM>.

If the photographing unit <NUM> is arranged at the first position (the position where the photographing unit <NUM> is accommodated in the auxiliary casing <NUM>), the locking member <NUM> is engaged with the hook member <NUM> of the latch unit <NUM>, and if the photographing unit <NUM> is arranged at the second position, (the position where the photographing unit <NUM> projects out of the auxiliary casing <NUM>). , the locking member <NUM> is released from the hook member <NUM> of the latch unit <NUM>.

The slider <NUM> is engaged with the photographing unit <NUM>, and is slidably mounted in the auxiliary casing <NUM> in the upper/lower direction (Z direction). The guide rail <NUM> is to guide sliding of the slider <NUM> in the upper/lower direction (Z direction), and is provided on each of both sides of the slider <NUM>. A guide slit <NUM> into which a side end portion of the slider <NUM> is inserted is formed on each of the guide rails <NUM>.

The elastic member <NUM> is a constituent element that provides a driving force for moving the slider <NUM> in the upper direction (+Z direction) when the locking of the photographing unit <NUM> is released. One end of the elastic member <NUM> is fixed to the slider <NUM>, and the other end of the elastic member <NUM> is fixed to the guide rail <NUM>. The elastic member <NUM> may include a spring, and in this embodiment, the elastic member <NUM> includes a torsion bar spring.

The damping member <NUM> is to adjust a sliding speed of the slider <NUM>. The damping member <NUM> includes a rotary damper, and is mounted to be engaged with a damper rail <NUM> that is provided on the guide rail <NUM>. During the sliding of the slider <NUM>, the damping member <NUM> is rotated along the damper rail <NUM> of the guide rail <NUM> to adjust the sliding speed of the slider <NUM>. Accordingly, the damper rail <NUM> of the guide rail <NUM> is also provided only on the guide rail <NUM> that is adjacent to the damping member <NUM>.

Hereinafter, referring to <FIG>, the configuration that guides the movement of the photographing unit <NUM> will be described in more detail.

<FIG> is an exploded cross-sectional view illustrating a photographing unit provided in the auxiliary casing of <FIG>, <FIG> is an exploded perspective view illustrating an engagement relationship between the auxiliary casing of <FIG> and a base casing of a photographing unit, and <FIG> is an exploded perspective view illustrating an engagement relationship between a photographing unit provided in the auxiliary casing of <FIG> and a slider.

Referring to <FIG>, slide guide grooves <NUM> are formed on both side surfaces of the base casing <NUM> of the photographing unit <NUM>. The respective slide guide grooves <NUM> are in the form of a curve that is gradually curved in the lower direction (-Z direction). Referring to <FIG>, a pair of guide projections <NUM>, which are respectively inserted into the pair of slide guide grooves <NUM> of the base casing <NUM>, are formed on a portion below the opening <NUM> of the front casing <NUM>. The pair of guide projections <NUM> are arranged to face each other. The pair of guide projections <NUM> are respectively inserted into the pair of slide guide grooves <NUM> to guide the sliding of the base casing <NUM> during the movement of the photographing unit <NUM>.

Referring to <FIG>, moving projections <NUM> are formed on end portions of both sides of the cover casing <NUM>. On the slider <NUM>, a pair of cover guide grooves <NUM>, into which the pair of moving projections <NUM> are inserted, are formed. The pair of cover guide grooves <NUM> guide the sliding of the cover casing <NUM> during the movement of the photographing unit <NUM>.

Hereinafter, the operation of the photographing unit <NUM>, which slides between the first position (the position where the photographing unit <NUM> is accommodated in the auxiliary casing <NUM>) and the second position (the position where the photographing unit <NUM> projects out of the auxiliary casing <NUM>), will be described in detail.

First, the operation of the photographing unit <NUM> which slides from the second position to the first position will be described.

<FIG> is a view explaining a sliding operation of a photographing unit when the photographing unit slides from a second position to a first position, <FIG> is a view explaining a moving trace of a photographing unit when the photographing unit slides from a second position to a first position, and <FIG> is a view explaining locking of a photographing unit.

Referring to <FIG>, during non-photographing, the user may accommodate the photographing unit <NUM> in the auxiliary casing <NUM>. Through this, the display apparatus <NUM> can keep the photographing unit <NUM> so that the photographing unit <NUM> is not seen from the front of the display apparatus <NUM> during the non-photographing.

As illustrated in portion A of <FIG>, the user presses the front surface of the photographing unit <NUM> with a finger during the non-photographing. In accordance with the user's pressing the front surface, the photographing unit <NUM> slides along the lower direction.

Referring to <FIG>, if the user presses the front surface of the photographing unit <NUM>, the photographing unit <NUM> moves from the second position to the first position through sliding to follow a curve or a curved trace C, and then is accommodated in the auxiliary casing <NUM>. Here, the curved trace C corresponds to the shape of the slide guide groove <NUM> of the photographing unit <NUM>. That is, the photographing unit <NUM> moves from the second position to the first position while drawing the curved trace C that corresponds to the shape of the slide guide groove <NUM>.

At this time, a certain point of the photographing unit <NUM> moves along the curved trace C that corresponds to the shape of the slide guide groove <NUM> from the position P1 in a state where the photographing unit <NUM> is arranged at the second position to the position P2 in a state where the photographing unit <NUM> is arranged at the first position. Other points of the photographing unit <NUM> may move in the same manner.

Thereafter, the user further presses the photographing unit <NUM> until the photographing unit <NUM> presses a somewhat lower portion of the opening <NUM> of the auxiliary casing <NUM>. This is to lock the photographing unit <NUM>, and the detailed explanation thereof will be made with reference to <FIG>.

Referring to <FIG>, during the movement of the photographing unit <NUM>, the slider <NUM> that is engaged with the photographing unit <NUM> slides in the lower direction (-Z direction) in the auxiliary casing <NUM>. At this time, the damping member <NUM> is engaged with the damper rail <NUM> of the guide rail <NUM> to be rotated, and prevents the slider <NUM> from abruptly move in the lower direction (-Z direction).

During the movement of the slider <NUM>, the latch unit <NUM> moves in the lower direction (-Z direction) of the auxiliary casing <NUM>. At this time, since the latch unit <NUM> and the locking member <NUM> are engaged with each other, the photographing unit <NUM> is locked in the first position.

As for the engagement of the latch unit <NUM> and the locking member <NUM>, the latch unit <NUM> moves in the lower direction (-Z direction) of the auxiliary casing <NUM> as described above, and thus the pair of hook members <NUM> come in contact with the engagement portion <NUM> of the locking member <NUM>. Thereafter, the pair of hook members <NUM> moves from the exposure position where the hook members are exposed out of the latch housing <NUM> to the insertion position where the hook members are partially inserted into the latch housing <NUM>. At this time, if the user releases the pressing of the photographing unit <NUM>, the slider <NUM> slightly moves in the upper direction (+Z direction) of the auxiliary casing <NUM> due to the spring provided inside the latch unit <NUM>. At this time, the pair of hook members <NUM> of the latch unit <NUM> get elastically closer to each other to be hook-engaged with the engagement portion <NUM> of the locking member <NUM>.

When the user releases the pressing of the front surface, the photographing unit <NUM> ascends to be somewhat higher than the height of the upper surface <NUM> of the auxiliary casing <NUM> as illustrated in <FIG> due to the movement of the auxiliary casing <NUM> of the slider <NUM> in the upper direction (+Z direction).

On the other hand, when the slider <NUM> moves in the lower direction (-Z direction), the elastic member <NUM> is extended in the lower direction (-Z direction), and an elastic pressing force is generated to force the slider <NUM> to return to the upper direction (+Z direction). This elastic pressing force may force the slider <NUM> to move in the upper direction (+Z direction) when the locking of the photographing unit <NUM> is released.

Next, the operation of the photographing unit <NUM> which slides from the first position to the second position will be described.

<FIG> is a view explaining a sliding operation of a photographing unit when the photographing unit slides from a first position to a second position, <FIG> is a view explaining locking release of a photographing unit, and <FIG> is a view explaining a moving trace of a photographing unit when the photographing unit slides from a first position to a second position.

Referring to <FIG>, during the photographing, the user may project the photographing unit <NUM> out of the display apparatus <NUM>. Through this, the display apparatus <NUM> can sense gestures of the user who is positioned in front of the display apparatus <NUM> through the photographing unit <NUM>.

As illustrated in portion A of <FIG>, during photographing, the user presses the front surface of the photographing unit <NUM> with a finger until the photographing unit <NUM> presses a somewhat lower portion of the opening <NUM> of the auxiliary casing <NUM>. This is to release the locking of the photographing unit <NUM>, and the detailed explanation thereof will be made with reference to <FIG>.

Referring to <FIG>, if the photographing unit <NUM> presses a somewhat lower portion of the opening <NUM> of the auxiliary casing <NUM>, the slider <NUM> slightly moves in the lower direction (-Z direction) of the auxiliary casing <NUM>. At this time, the pair of hook members <NUM> of the latch unit <NUM> are pushed to the exposure position where the hook members are exposed out of the latch housing <NUM> due to the internal spring. If the pair of hook members <NUM> are exposed out of the latch housing <NUM>, they are elastically spaced apart from each other and are separated from the engagement portion <NUM> of the locking member <NUM>. Through this, the locking of the photographing unit <NUM> is released in the auxiliary casing <NUM>.

If the locking of the photographing unit <NUM> is released, the elastic member <NUM> provides an elastic pressing force in the upper direction (+Z direction) of the auxiliary casing <NUM> so that the slider <NUM> can move in the upper direction (+Z direction) of the auxiliary casing <NUM>. Due to the elastic pressing force provided by the elastic member <NUM>, the slider <NUM> slides in the upper direction (+Z direction) of the auxiliary casing <NUM>. At this time, the damping member <NUM> is engaged with the damper rail <NUM> of the guide rail <NUM> to be rotated, and prevents the slider <NUM> from abruptly move in the upper direction (+Z direction). During the movement of the slider <NUM> in the upper direction (+Z direction), the photographing unit <NUM> slides together to project out of the auxiliary casing <NUM>. The sliding of the photographing unit <NUM> will be described in detail with reference to <FIG>.

Referring to <FIG>, through the sliding to follow the curved trace C, the photographing unit <NUM> moves from the first position to the second position and then projects out of the auxiliary casing <NUM>. Here, the curved trace C corresponds to the shape of the slide guide groove <NUM> of the photographing unit <NUM> as described above with reference to <FIG>. That is, the photographing unit <NUM> moves from the first position to the second position while drawing the curved trace C that corresponds to the shape of the slide guide groove <NUM>.

At this time, a certain point of the photographing unit <NUM> moves along the curve or curved trace C that corresponds to the shape of the slide guide groove <NUM> from the position P2 in a state where the photographing unit <NUM> is arranged at the first position to the position P1 in a state where the photographing unit <NUM> is arranged at the second position. Other points of the photographing unit <NUM> may move in the same manner.
