Abstract

A display apparatus includes an antistatic coating disposed sequentially on the cover member, the display panel and the cushion plate, wherein the antistatic coating is configured to include a plurality of rod-shaped nanowires, thereby improving conductivity of the antistatic coating and effectively reducing a brightening phenomenon where light emission gets brighter at an end or on a side than other areas of the display panel.

Claims (31)

1. A display apparatus comprising:

a display panel configured to display images;

a cover member disposed upon the display panel and protecting the display panel from external shocks;

a cushion plate disposed below the display panel and providing cushioning and heat dissipation for the display panel; and

an antistatic coating extended from the cover member to the cushion plate and comprising a plurality of nanowires,

wherein the antistatic coating is in direct contact with a side of the display panel and a side of the cushion plate, and

wherein at least one of a rear surface of the cover member and a rear surface of the heat dissipation layer has a horizontal line pattern engraved with a number of grooves along a horizontal direction corresponding to an X-axis direction of the display panel.

2. The display apparatus of claim 1 , wherein the plurality of nanowires have a shape of a circular or a polygonal rod and are formed of at least one or more materials of silver (Ag), copper (Cu) and nickel (Ni).

3. The display apparatus of claim 2 , wherein the plurality of nanowires have a bent rod shape.

4. The display apparatus of claim 1 , wherein the antistatic coating is disposed with a plurality of nanowires connected from the cover member to the cushion plate.

5. The display apparatus of claim 1 , wherein the antistatic coating further comprises a plurality of conductive balls.

6. The display apparatus of claim 1 , wherein the cushion plate comprises a cushion layer and a heat dissipation layer disposed below the cushion layer.

7. The display apparatus of claim 6 , wherein at least one of a rear surface of the cover member and a rear surface of the heat dissipation layer has a diagonal line pattern engraved with a number of grooves along a diagonal direction between X-axis and Y-axis of the display panel.

8. The display apparatus of claim 7 , wherein the plurality of nanowires are disposed in the grooves of the horizontal line pattern or the diagonal line pattern.

9. The display apparatus of claim 1 , wherein at least one of a side of the display panel and a side of the cushion plate has a lateral horizontal line pattern engraved with a number of grooves along a thickness direction corresponding to a Z-axis direction of the display panel, or a lateral diagonal line pattern engraved with a number of grooves along a diagonal direction of a thickness direction between the Z-axis and a Y-axis of the display panel.

10. The display apparatus of claim 6 , wherein the plurality of nanowires are disposed in the grooves of the lateral horizontal line pattern, or the lateral diagonal line pattern.

11. The display apparatus of claim 1 , further comprising a first connecting member connecting the display panel and the cover member.

12. The display apparatus of claim 11 , wherein the antistatic coating is disposed sequentially on a rear surface of the cover member, a side surface of the first connecting member, a side surface of the display panel, a side surface and a rear surface of the cushion plate.

13. The display apparatus of claim 1 , wherein the cushion plate comprises:

a porous member comprising a conductive metal and a plurality of pores disposed inside the conductive metal; and

an adhesive layer disposed on the porous member.

14. A method of disposing an antistatic coating, the method comprising:

forming an antistatic solution by mixing nanowires with a solvent comprising at least one or more materials of acetone, water, isopropyl alcohol and ethanol;

applying the antistatic solution in a display apparatus; and

drying the antistatic solution,

wherein the display apparatus comprises:

a display panel configured to display images; and

a cushion plate disposed below the display panel and providing cushioning and heat dissipation for the display panel,

the antistatic solution is applied directly to a side of the display panel and a side of the cushion plate,

wherein at least one of a rear surface of the cover member and a rear surface of the heat dissipation layer has a horizontal line pattern engraved with a number of grooves along a horizonal direction corresponding to an X-axis direction of the display panel.

15. The method of claim 14 , wherein the drying of the antistatic solution including a drying at temperature between 20 to 30 Celsius degree for 7 to 15 minutes.
