Patent Description:
Embodiments of the present disclosure relate to a display device.

In general, liquid crystal display (LCD) devices, plasma display devices, field emission display devices, and light emitting display devices are under active research in the field of flat display devices. Among them, the LCD devices and the light emitting display devices have attracted attention in view of their benefits of mass production, ease of driving means, and high image quality.

However, such display devices have gradually increased in volume (i.e., size) to meet the needs of users for a larger screen, thereby increasing risk of damage to the display panel and requiring a larger space for installation, which makes users difficult to secure the space.

In addition, in order to provide an always-on-display mode that continuously displays various information desired by the users of the display, an always-on-display device is required in addition to the general display device in a normal mode, which makes it difficult to satisfy various users demands.

Therefore, to solve the aforementioned problems and to provide a display device which provides more diverse uses to users, there is a need for research on providing a display device engaged with furniture, equipment, facilities, etc., to implement various forms of display.

Hereinafter, in the following description of embodiments of the present disclosure, the module housing <NUM> can be built in inside of a support portion <NUM>, the support portion <NUM> can correspond to a leg, such as a leg of a bed, which is the most common furniture, but could be any other piece of furniture or other suitable support portion. The display panel <NUM> can display while the display panel <NUM> and the rear cover <NUM> are pulled up to the upper portion of the bed or pulled down from the upper portion of the bed.

In addition, a display device according to embodiments of the present disclosure can provide either of an always-on-display mode (AOD mode), that continuously displays information such as a clock, weather or news, and a normal mode that displays an image or video intended (i.e., selected) by a user.

As illustrated in <FIG>, in usual time, most of the display panel <NUM> is covered inside the module housing <NUM> as only a portion of the display panel <NUM> is pulled up, and the always-on-display mode can be provided.

<FIG> is illustrated as the module housing <NUM> is installed by forming an empty space inside of the support portion <NUM> of the main housing <NUM> when the always-on-display mode is provided. For example, the module housing <NUM> can be provided inside of the support portion <NUM> of the main housing <NUM>, when the always-on display mode is activated.

<FIG> is illustrated as the normal mode is provided with holding the display screen to the full size (i.e., fully extended position) when the display panel <NUM> is pulled up.

The module housing <NUM> has a rectangular shape and the module housing <NUM> accommodates the display panel <NUM>, the first moving plate <NUM>, the second moving plate <NUM>, the first driving member <NUM>, the second driving member <NUM>, a first fixed plate <NUM> and a second fixed plate <NUM>. The module housing <NUM> is partially omitted in the drawings for convenience of description.

A front cover <NUM>, the first fixed plate <NUM>, the first moving plate <NUM>, the display panel <NUM>, the second fixed plate <NUM>, the second moving plate <NUM> and the rear cover <NUM> are sequentially stacked and accommodated with respect to the front surface of the module housing <NUM>. For example, with respect to the display panel, the first fixed plate <NUM> is positioned on an opposite side of the display panel from the second fixed plate <NUM>.

The display panel <NUM> is coupled to the rear surface of the first moving plate <NUM> and pulled up and down with the first moving plate <NUM>. According to embodiments of the present disclosure, the display panel <NUM> can be either an LCD panel or a light emitting display panel, but is not limited thereto.

For example, when the display panel is an LCD panel, the display panel can further include a backlight unit (i.e., backlight) irradiating light onto the LCD panel, a lower polarization plate attached to a lower substrate, and an upper polarization plate attached to the front surface of an upper substrate. The specific configurations of the lower substrate and the upper substrate can vary according to driving modes of the LCD panel, for example, a twisted nematic (TN) mode, a vertical alignment (VA) mode, an in plane switching (IPS) mode, and a fringe field switching (FFS) mode.

Further, when the display panel is a light emitting display panel, the light emitting display panel can include a lower substrate with a plurality of light emitting cells formed in the areas each of which is defined by gate lines, data lines, and power (VDD) lines, and an upper substrate bonded to the lower substrate face to face. Drawings and a detailed description of the light emitting display panel are not provided herein.

As described above, the display panel is not limited to any particular type in embodiments of the present disclosure. For example, the display panel can be made up of a flexible substrate that is bendable, in embodiments of the present disclosure. The following description is given irrespective of display panel types.

The first moving plate <NUM> is coupled to the display panel <NUM> and the opposite sides of the first moving plate <NUM> have belt coupling portions <NUM> to which the first driving belt <NUM> is coupled. The first moving plate <NUM> moves along first guide bars 161a, 161b, to be described below, with the display panel <NUM>, when the first driving belt <NUM> is wound or released by the first driving member <NUM>.

In addition, a control printed circuit board <NUM>, which is connected to a source printed circuit board <NUM> of the display panel <NUM> via a flexible circuit film, is fixed to the first moving plate <NUM>. Thus, the control printed circuit board <NUM>, which is connected to a main board <NUM> and a power board <NUM>, to be described below, is stably fixed when the first moving plate <NUM> and the display panel <NUM> move.

The belt coupling portions <NUM> are provided at the opposite sides of the first moving plate <NUM> and are respectively fixed to a first end 152a and a second 152b of the first driving belt <NUM>. Thus, the belt coupling portions <NUM> are pulled up and down with the first moving plate <NUM> by the first driving belt <NUM>.

The first fixed plate <NUM> coupled to the module housing <NUM> and the first driving member <NUM> is provided between the front cover <NUM> and the first moving plate <NUM>.

Each of elastic belts <NUM> includes a first end 181b fixed to the first moving plate <NUM> and a second end 181a fixed to the first fixed plate <NUM>. Belt rollers <NUM> are fixed to the first fixed plate <NUM>, and the elastic belts <NUM> are wound on (i.e., around) the belt rollers <NUM> and are rotatably supported by the belt rollers <NUM>, respectively.

The elastic belts <NUM> are configured to provide a tensile force to the first moving plate <NUM> at the pulled down position. Thus, the driving force of a first driving motor <NUM> is assisted by the tensile force of the elastic belts <NUM> when the first moving plate <NUM> is pulled up.

Therefore, the elastic belts reduce a force required to pull up the first moving plate <NUM> and maintain the first moving plate <NUM> horizontally when the first moving plate <NUM> is pulled up and pulled down.

A main board <NUM> and a power board <NUM> are fixed to the first fixed plate <NUM> and are disposed in front of the first moving plate <NUM>. An image processor electrically connected to the control printed circuit board <NUM> and supplying a data signal and a control signal to the display panel <NUM> is mounted on the main board <NUM>. The power board <NUM> supplies power to the display panel <NUM>.

A position sensor <NUM> coupled to the first fixed plate <NUM> senses and transmits the position of the display panel <NUM> to the main board <NUM>. The main board <NUM> controls the display panel <NUM> to either of the always-on-display mode and normal mode according to the position of the display panel <NUM>.

The position of the display panel <NUM>, which determines the display panel <NUM> to the always-on-display mode can be set in advance. As illustrated in <FIG>, embodiments of the present disclosure can be provided with the main board <NUM> that controls the display panel <NUM> to the always-on-display mode when the display panel <NUM> is pulled up to a preset position, including a preset position of the upper portion of the bed, by way of example.

A data cable 121a connects the main board <NUM> and the control printed circuit board <NUM>, and a cable penetrating member <NUM> protects a power cable 123a connecting the power board <NUM> and the control printed circuit board <NUM>.

A first end 140a of the cable penetrating member <NUM> is coupled to the first fixed plate and a second end 140b of the cable penetrating member <NUM> is coupled to a fixed flange <NUM> of the first moving plate <NUM>. Thus, the second end 140b of the cable penetrating member <NUM> is pulled up and down with the first moving plate <NUM>.

The cable penetrating member <NUM> includes a plurality of connecting members <NUM> rotatably connected to each other via hinge portions <NUM> and having empty space inside thereof. The data cable 121a and the power cable 123a penetrate the cable penetrating member <NUM> from a first end to a second end. The cable penetrating member <NUM> maintains "U" shape which the lengths of both sides of the penetrating member <NUM> change when the first moving plate <NUM> is pulled up and down, thereby preventing the cable 121a, 123a from interference with surrounding electronic components while pulled up and down.

The first driving member <NUM>, which pulls up and down the first moving plate <NUM>, includes a first driving motor <NUM> coupled to the first fixed plate <NUM>, a first driving gear <NUM> and a first driven gear <NUM> rotated by the first driving motor <NUM>, a first driving pulley 153a coupled coaxially to the first driven gear <NUM> to wind or release the first driving belt <NUM>, first driven pulleys 155a, 155b connected to the first driving pulley 153a by the first driving belt <NUM> and coupled to the first fixed plate <NUM>.

The first driving motor <NUM> rotates the first driving pulley 153a with the number of revolutions reduced by the constant gear ratio between the first driving gear <NUM> and the first driven gear <NUM>. The opposite ends of the first driving belt <NUM> are coupled to the first driving pulley <NUM> to be wound in the same direction.

Therefore, the first moving plate <NUM> and the display panel <NUM> are pulled up as the first driving belt <NUM> is wound, when the first driving pulley 153a rotates in one direction (e.g., a first direction), and the first moving plate <NUM> and the display panel <NUM> are pulled down as the first driving belt <NUM> is released when the first driving pulley 152a rotates in the opposite direction (e.g., a second direction).

As illustrated in <FIG>, in which the front surface of the first moving plate <NUM> and the display panel <NUM> is illustrated, the first moving plate <NUM> and the display panel <NUM> are pulled up when the first driving pulley <NUM> rotates clockwise.

In addition, the first driving member <NUM> further includes first guides bars 161a, 161b respectively fixed to opposite ends of the module housing <NUM>, and first moving guides 165a, 165b coupled to the belt coupling portions <NUM> of the first moving plate <NUM> and pulled up and down along the first guide bars 161a, 161b, respectively.

The first moving guides 165a, 165b coupled to the first moving plate <NUM> are pulled up and down along the first guide bars 161a, 161b. Thus, the first moving plate <NUM> is stably pulled up and down without being biased to either side while the driving force of the first driving motor <NUM> pulls up and down the first moving plate <NUM> via the first driving belt <NUM>.

The first guide bars 161a, 161b and the first moving guides 165a, 165b are disposed at the opposite sides of the module housing <NUM> and the first moving plate <NUM> is guided by the first guide bars 161a, 161b and the first moving guides 165a, 165b when pulled up and down. <FIG> illustrates the first moving plate <NUM> that is in the pulled down position, and <FIG> illustrates the first moving plate <NUM> that is in the pulled up position, the first moving plate <NUM> being illustrated with dotted lines.

An upper cover <NUM> having an entry/exit hole 105a which the display panel <NUM> passes is coupled to the upper portion of the module housing <NUM>. The user can stow the display panel <NUM> is as to not be exposed or can use the display panel <NUM> to always-on-display mode.

The display panel <NUM> can be pulled down under of the upper cover <NUM> not to be exposed. Thus, the display panel <NUM> is protected from external impact and occupies minimized space.

In addition, a cover plate <NUM> coupled to the module housing <NUM> is provided under the upper cover <NUM>. A support roller <NUM> supporting the front and rear surface of the display panel <NUM> is coupled to the cover plate <NUM>. The support roller <NUM> can be provided as a pair, including a first support roller <NUM> provided at the front surface of the display panel <NUM>, and a second support roller provided at the rear surface of the display panel, as shown in <FIG>.

The support roller <NUM> is provided as a couple of rollers supporting the front and rear surface of the display panel <NUM>, respectively, and rotatably coupled to a fixed bracket <NUM> coupled to the cover plate <NUM>.

Therefore, the support roller <NUM> rolls when the display panel <NUM> is pulled up and down, and supports the display panel <NUM>, so as to avoid or prohibit shaking of the display panel <NUM>. Especially, the pulled up display panel <NUM> is stably supported by the support roller <NUM>.

A second fixed plate <NUM> coupled to the module housing <NUM> and the second driving member <NUM> is provided between the rear cover <NUM> and the display panel <NUM>.

The rear cover <NUM> can be pulled up and down with the distance equal to the pulled up and down distance of the display panel <NUM>, or can be pulled up and down with the separate distance which the user intended, by the second driving member <NUM>.

The second fixed plate <NUM> includes guide holes <NUM> to guide the second moving plate <NUM> pulled up and down. The guide holes <NUM> can be spaced apart from one another and provided at opposing sides of the second fixed plate <NUM>. The front surface of the second moving plate <NUM> includes guide protrusions <NUM> inserted into the guide holes <NUM>, respectively.

Therefore, the second moving plate <NUM> is stably pulled up and down with the rear cover <NUM> without being biased to either side.

The guide protrusions <NUM> of the second moving plate <NUM> inserted into the guide holes <NUM> are coupled to the moving members 265a, 265b disposed on the front surface of the second fixed plate <NUM>, respectively. The guide protrusions <NUM> are pulled up and down with the moving members 265a, 265b. Thus, the rear cover <NUM> is stably pulled up and down while supported to the guide holes <NUM> with the second moving plate <NUM> and the moving members 265a, 265b.

The guide holes <NUM> can be symmetrically disposed at the opposite sides respect to the center of the second moving plate <NUM> and the guide protrusions <NUM> provided as a pair at the second moving plate <NUM> and positioned according to the guide holes <NUM> are illustrated, by way of example. Three or more of the guide holes <NUM> and the guide protrusions <NUM> can be provided, respectively, to stably pull up and down the rear cover <NUM> even more.

The second driving member <NUM>, which pulls up and down the second moving plate <NUM>, includes a second driving motor <NUM> coupled to the second fixed plate <NUM>, a second driving gear <NUM> and a second driven gear <NUM> rotated by the second driving motor <NUM>, a second driving pulley 253a coupled coaxially to the second driven gear <NUM> to wind or release the second driving belt <NUM>, second driven pulleys 255a, 255b connected to the second driving pulley 253a by the second driving belt <NUM> and coupled to the second fixed plate <NUM>. The opposite ends 252a, 252b of the second driving belt <NUM> are coupled to the bracket <NUM> provided on the moving members 265a, 265b, and the moving members 265a, 265b are pulled up and down as the second driving belt <NUM> is wound or released.

The second driving motor <NUM> rotates the second driving pulley 253a with the number of revolutions reduced by the constant gear ratio between the second driving gear <NUM> and the second driven gear <NUM>. The opposite ends of the second driving belt <NUM> are coupled to the second driving pulley 253a to be wound in the same direction.

Therefore, the second moving plate <NUM> and the rear cover <NUM> are pulled up as the second driving belt <NUM> is wound, when the second driving pulley 253a rotates in one direction (e.g., a first direction), and the second moving plate <NUM> and the rear cover <NUM> are pulled down as the second driving belt <NUM> is released, when the second driving pulley 253a rotates in the opposite direction (e.g., a second direction).

In addition, the second driving member <NUM> further includes second guide bars 261a, 261b including opposites ends fixed to the module housing <NUM>. The moving members 265a, 265b are coupled to the second moving plate <NUM> and are pulled up and down along the second guide bars 261a, 261b, respectively.

The moving members 265a, 265b coupled to the second moving plate <NUM> are pulled up and down along the second guide bars 261a, 261b. Thus, the second moving plate <NUM> is stably pulled up and down without being biased to either side while the driving force of the second driving motor <NUM> pulls up and down the second moving plate <NUM> via the second driving belt <NUM>.

The second guide bars 261a, 261b are disposed at the opposite sides of the module housing <NUM> and guide the second moving plate <NUM> to be pulled up and pulled down.

The rear cover <NUM> includes magnet plates 120a disposed along the direction of pulling up and down. The upper portion of the second fixed plate <NUM> includes magnets <NUM> correspondingly positioned to the magnet plates 120a.

The magnet plates 120a are disposed at the center portion and the opposite sides, which are symmetric, in the direction of pulling up and down, thereby enhancing the rigidity of the rear cover <NUM> and preventing the rear cover <NUM> from shaking.

The magnet plates 120a and the magnets are configured to attract each other, and the rear cover <NUM> is supported by the attracting magnet force while pulled up and down. Especially, the supporting force becomes larger when the rear cover is partially pulled up not wholly, like the always-on-display mode.

The upper portion of the second fixed plate <NUM> includes cover support rollers <NUM> supporting the front surface of the rear cover <NUM> when the rear cover <NUM> is pulled up and down. The cover support roller <NUM> rolls when the rear cover <NUM> is pulled up and down and supports the rear cover <NUM> not to be shaken, especially not to be inclined toward the display panel <NUM> at the upper portion of the second fixed plate <NUM>.

As illustrated in <FIG>, cut-out holes <NUM> are provided at the upper portion of the second fixed plate <NUM>, nearby the magnets <NUM>, to stably couple the cover support rollers <NUM>. The cover support rollers <NUM> are inserted into the cut-out holes <NUM> and are coupled to the upper portion of the second fixed plate <NUM> via a bracket 205a.

The magnets are exposed in the front direction of the rear cover <NUM> through the magnet holes 203b, and are coupled to the rear surface of the second fixed plate <NUM> via magnet holders 203a.

Therefore, the cover support rollers <NUM> support the rear cover <NUM> at a portion which the attracting force between the rear cover <NUM> and the magnets <NUM> is strongest, thereby supporting the rear cover <NUM> not to be biased either in front or in rear (i.e., in the front or rear directions).

As described above, according to embodiments of the present disclosure, a display device allowing a user to freely accommodate a display panel in a housing so as not to be externally exposed, or to change display device between an always-on-display mode and the normal mode when the user needs.

Further, according to embodiments of the present disclosure, a display device configured to be mounted without being constrained by an additional mounting space, thereby using a space efficiently, and to reduce a risk of damage due to an external impact by minimizing the external exposure of the display panel, thereby satisfying various user demands.
