Abstract

A display device may include a module housing accommodating a display panel pulled up and down, a moving plate accommodated in the module housing and pulled up and down with the display panel, a driving member pulling up and down the moving plate and the display panel, and a fixed plate coupled to an inside of the module housing and to which the driving member is fixed.

First claim

What is claimed is:

1. A display device comprising:
a module housing configured to accommodate a display panel pulled up and down;
a moving plate accommodated in the module housing and pulled up and down with the display panel, the moving plate including a front surface coupled to the display panel and a rear surface provided with moving brackets to which a driving belt is coupled;
a driving member configured to pull up and down the moving plate by winding or releasing the driving belt; and
a fixed plate coupled to an inside of the module housing and to which the driving member is fixed,
wherein one of the moving brackets is provided with a through hole penetrated by a flexible circuit film connected to a source printed circuit board of the display panel.

2. The display device according to claim 1 , further comprising:
a control printed circuit board to which the flexible circuit film penetrating the through hole is bent and connected,
wherein the control printed circuit board is fixed to the moving brackets.

3. The display device according to claim 2 , further comprising:
a main board and a power board fixed to the fixed plate,
wherein the power board supplies power to the display panel.

4. The display device according to claim 3 , further comprising:
a position sensor coupled to the fixed plate and configured to sense and transmit a position of the display panel to the main board,
wherein the main board controls the display panel as an always-on-display mode when an end portion of the display panel is overlapped with a preset position.

5. The display device according to claim 3 , wherein the display device further comprises:
a cable penetrating member including one end coupled to the fixed plate and another end coupled to the moving plate;
a data cable connecting the main board and the control printed circuit board; and
a power cable connecting the power board and the control printed circuit board to penetrate an inside of the cable penetrating member.

6. The display device according to claim 5 , wherein the cable penetrating member includes a plurality of connecting members rotatably connected to each other,
each of the connecting members has a couple of first connecting portions disposed opposite to each other and a couple of second connecting portions disposed opposite to each other,
the first connecting portions are extended in one direction from a center portion provided with an empty space through which the data cable and the power cable pass, and
the second connecting portions are extended in a direction opposite to the one direction from the center portion.

7. The display device according to claim 6 , wherein the first connecting portions are provided with connecting holes,
the second connecting portions are provided with rotation protrusions, and
the first connecting portions and the second connecting portions overlapped with the first connecting portions are coupled when the rotation protrusions are inserted to the connecting holes.

8. The display device according to claim 6 , wherein the connecting members disposed at one end and another end of the cable penetrating member are provided with coupling holes.

9. The display device according to claim 1 , wherein the module housing is built in and fixed inside of a main housing, and
the display panel is pulled up to an upper portion of the main housing or pulled down from the upper portion of the main housing.

10. The display device according to claim 1 , wherein the display panel, the moving plate and the fixed plate are sequentially stacked from a front side to a rear side of the module housing.

11. A display device comprising:
a module housing configured to accommodate a display panel pulled up and down;
a moving plate accommodated in the module housing and pulled up and down with the display panel, the moving plate including a front surface coupled to the display panel and a rear surface provided with moving brackets to which a driving belt is coupled;
a driving member configured to pull up and down the moving plate by winding or releasing the driving belt; and
a fixed plate coupled to an inside of the module housing and to which the driving member is fixed,
wherein the driving member comprises:
a driving motor coupled to the fixed plate;
a driving gear and a driven gear rotated by the driving motor;
a driving pulley coupled coaxially to the driven gear to wind or release the driving belt;
driven pulleys connected to the driving pulley by the driving belt and coupled to the fixed plate;
guide bars each including opposite ends fixed to the module housing; and
moving guides coupled to one side of the moving plate and pulled up and down along the guide bars, respectively,

wherein the driving member includes elastic belts having one end coupled to the moving guides and another end fixed to the module housing, and
belt rollers fixed to the fixed plate and the elastic belts are wound on the belt rollers and rotatably supported by the belt rollers.

12. A display device comprising:
a module housing configured to accommodate a display panel pulled up and down;
a moving plate accommodated in the module housing and pulled up and down with the display panel, the moving plate including a front surface coupled to the display panel and a rear surface provided with moving brackets to which a driving belt is coupled;
a driving member configured to pull up and down the moving plate by winding or releasing the driving belt; and
a fixed plate coupled to an inside of the module housing and to which the driving member is fixed,
wherein a sliding door which is closed when the display panel is drawn in and is opened when the display panel is drawn out by being slid in front and rear directions of the module housing, is provided at an upper portion of the module housing,
wherein the display device further comprises:
door levers each including one end coupled to the sliding door and another end rotatably coupled to the fixed plate, and
wherein each of the door levers is rotatably coupled to a hinge bracket coupled to the fixed plate with a hinge axis, and is supported by a sliding rail coupled to the moving plate by a rotation supporting member provided at a support hole of the each door lever spaced apart from the hinge axis.

13. The display device according to claim 12 , wherein a guide groove into which the rotation supporting member is inserted is provided inside of the sliding rail, and
the guide groove includes a top guide groove and a bottom guide groove having parallel center lines and connected via a curved groove.
