Abstract

A display apparatus include a display module, a cover plate, and a lifting module. The display module includes a display panel that displays an image in a display area. The display area includes an Always On Display (AOD) area. The cover plate covers a portion of the display module. The lifting module moves vertically the cover plate. At least the AOD area of the display area is not covered with the cover plate and is exposed to an outside. AOD data is displayed in the AOD area. Thus, an AOD function can be implemented.

First claim

What is claimed is:

1. A display apparatus comprising:
a display module including a display panel for displaying an image in a display area;
a cover plate covering a portion of the display area; and
a lifting module disposed on a rear face of the display module to lift up or lower down the cover plate,
wherein the display area includes an Always On display (AOD) area,
wherein when the cover plate ascends via activation of the lifting module, the display area includes a first area that is flat and which is covered with the cover plate and a second area that is flat and which is exposed to outside, and
wherein the AOD area is included in the second area.

2. The display apparatus of claim 1 , wherein the display module displays AOD data in the AOD area, based on an AOD request signal received via a user input interface.

3. The display apparatus of claim 1 , wherein the display module operates in one of a plurality of view modes,
wherein the plurality of view modes include a first mode in which an image is displayed in an entirety of the display area, and a second mode in which an image is displayed in the AOD area of the display area, and
wherein in the second mode, the first area is a remaining area of the display area except for the AOD area.

4. The display apparatus of claim 3 , wherein the cover plate ascends via activation of the lifting module until the cover plate covers the remaining area of the display area except for the AOD area, based on a second mode request signal received via the user input interface.

5. The display apparatus of claim 3 , wherein in the first mode, the entirety of the display area of the display module is exposed to the outside, and
wherein the cover plate descends via activation of the lifting module until the entirety of the display area is exposed to the outside, based on a first mode request signal received via the user input interface.

6. The display apparatus of claim 3 , wherein the plurality of view modes further include a third mode in which an image is displayed in a cinema area of the display area, and the third mode corresponds to a screen ratio different from a screen ratio corresponding to the first mode, and
wherein the cover plate is lifted up or lowered down via activation of the lifting module until the cover plate covers a remaining area of the display area except for the cinema area, based on a third mode request signal received via the user input interface.

7. The display apparatus of claim 1 , wherein the cover plate includes:
a front portion facing to the display area; and
two side portions respectively disposed on both opposing sides of the front portion,
wherein each of the side portions is bent to surround a portion of a side of the display module, and extends toward the rear face of the display module, and
wherein a vertical dimension of each side portion is larger than a vertical dimension of the front portion.

8. The display apparatus of claim 7 , wherein the display module further includes:
a backplate facing a rear face of the display panel and fixed to the display panel; and
a side cover surrounding a top and sides of each of the display panel and the backplate,
wherein a side of the side cover includes a cover area corresponding to the cover plate and a protruding area protruding beyond the cover area, and
wherein the protruding area acts as a stopper to limit a vertical movement of the cover plate via activation of the lifting module.

9. The display apparatus of claim 8 , wherein the display module further includes a driver circuit board disposed on one edge of the rear face of the display panel,
wherein a driver chip configured to drive a signal line of the display panel is mounted on the driver circuit board, and
wherein the backplate has at least one opening defined therein to expose the driver circuit board.

10. The display apparatus of claim 9 , wherein the display module further includes at least one printed circuit board connected to the display panel or the driver circuit board to supply a signal for driving the display panel, and
wherein the at least one printed circuit board and at least a portion of the lifting module are disposed in a rear face storage area defined by the backplate and the side cover.

11. A display apparatus comprising:
a display module including a display panel having a display area for displaying an image;
a cover plate covering a portion of the display module; and
a lifting module disposed on a rear face of the display module opposite to the display area of the display panel, wherein the lifting module is configured to lift up or lower down the cover plate,
wherein the display module operates in one of a plurality of view modes respectively corresponding to different vertical levels of the cover plate,
wherein the plurality of view modes include:
a first mode in which an image is displayed in an entirety of the display area;
a second mode in which an image is displayed an image in an Always On Display (AOD) area of the display area; and
a third mode in which an image is displayed in a cinema area of the display area, the third mode corresponding to a screen ratio different from a screen ratio corresponding to the first mode,

wherein in the second mode, a remaining area of the display area except for the AOD area is covered with the cover plate, and
wherein the cover plate ascends to a highest level corresponding to the second mode via activation of the lifting module, based on a second mode request signal received via a user input interface.

12. The display apparatus of claim 11 , wherein in the second mode, the display module displays AOD data in the AOD area, based on an AOD request signal received via the user input interface.

13. The display apparatus of claim 11 , wherein in the first mode, the entirety of the display area is exposed to outside, and
wherein the cover plate descends to a lowest level corresponding to the first mode via activation of the lifting module, based on a first mode request signal received via the user input interface.

14. The display apparatus of claim 11 , wherein in the third mode, the cinema area of the display area is exposed to outside and a remaining area of the display area except for the cinema area is covered with the cover plate, and
wherein the cover plate is lifted up or lowered down via activation of the lifting module until the cover plate is located at a predefined level corresponding to the third mode, based on a third mode request signal received via the user input interface.

15. The display apparatus of claim 11 , wherein the cover plate includes:
a front portion facing to the display area; and
two side portions respectively disposed on both opposing sides of the front portion, wherein each of the side portions is bent to surround a portion of a side of the display module, and extends toward the rear face of the display module,
wherein a vertical dimension of each side portion is larger than a vertical dimension of the front portion.

16. The display apparatus of claim 11 , wherein the display module further includes:
a backplate facing a rear face of the display panel and fixed to the display panel; and
a side cover surrounding a top and sides of each of the display panel and the backplate,
wherein a side of the side cover includes a cover area corresponding to the cover plate and a protruding area protruding beyond the cover area, and
wherein the protruding area acts as a stopper to limit a vertical movement of the cover plate via activation of the lifting module.
