Abstract

Provided is a display apparatus. The display apparatus includes a display panel, a back cover disposed on a rear side of the display panel, the back cover having a curved shape of which both ends protrude forward, and a fixing part fixing the back cover to maintain the curved shape of the back cover. The display panel is curved in a shape corresponding to that of the back cover.

First claim

What is claimed is:

1. A display apparatus, comprising:
a display panel configured to display images;
a back cover coupled to and covering a rear surface of the display panel;
an incurvating device on a rear surface of the back cover to transform the display panel from a flat state to an incurvated state, the incurvating device configured to push side portions of the rear surface of the back cover;
a printed circuit board disposed behind the back cover;
a bracket coupled to the rear surface of the back cover at a position away from the incurvating device, wherein the printed circuit board is coupled to the bracket; and
a rear cover covering at least a portion of the rear surface of the back cover, wherein the printed circuit board is covered by the rear cover, wherein the incurvating device includes:
a pushing device configured to push the side portions of the rear surface of the back cover, the pushing device including:
a first pushing member having a first end thereof in contact with a first side portion of the rear surface of the back cover, and
a second pushing member having a first end thereof in contact with a second side portion of the rear surface of the back cover; and

a driver to operate the pushing device to push the first and second side portions of the rear surface of the back cover, the driver disposed at a central portion of the rear surface of the back cover, and wherein second ends of the first and second pushing members are respectively connected to the driver such that the driver simultaneously drives both the first and second pushing members, and wherein when the display panel moves from the flat state to the incurvated state, the bracket and the printed circuit board are maintained in an original flat shape, and when the display panel moves from the incurvated state to the flat state, the bracket and the printed circuit board are maintained in the original flat shape.

2. The display apparatus of claim 1 , wherein the driver is configured to simultaneously transfer driving force to the second ends of the first and second pushing members, and wherein the first ends of the first and second pushing members move inward towards a central portion of the display panel in response to the driving force transferred to the second ends of the first and second pushing members.

3. The display apparatus of claim 2 , wherein the first and second pushing members are first and second plates coupled to the rear surface of the back cover.

4. The display apparatus of claim 3 , wherein the driver includes a rotating device contacting second ends of the first and second plates.

5. The display apparatus of claim 4 , further comprising a fixed device fixed to the central portion of the rear surface of the back cover, wherein the second ends of the first and second plates contact at least one of the fixed device or the rotating device.

6. The display apparatus of claim 5 , wherein the rotating device includes a cam, wherein the second ends of the first and second plates contact an outer surface of the cam, and wherein when the cam rotates in a first direction, the second ends of the first and second plates are pushed by the cam and the first ends of the first and second plates move inward towards the center portion of the display panel.

7. The display apparatus of claim 6 , wherein the cam is connected to the fixed device and moves forward or backward by rotation of the cam.
