Abstract

Provided is a flexible organic light-emitting diode display. The flexible organic light-emitting diode display includes a flexible substrate, a unit pixel and an anti-reflection layer. The unit pixel is disposed on the flexible substrate and includes an emission area and a non-emission area. The anti-reflection layer is disposed to correspond to the emission area except the non-emission area.

Claims (17)

1. A flexible organic light-emitting diode display comprising:

a display panel with a display area and a non-display area, the display panel comprising:

a flexible substrate configured to be bended in a second direction, and

a plurality of unit pixels disposed on the flexible substrate arranged in a first direction, wherein each of the plurality of unit pixels includes an emission area in the display area of the display panel and a non-emission area in the display area of the display panel; and

an anti-reflection layer disposed on a front side of the display panel,

wherein the anti-reflection layer covers areas of the display panel corresponding to the emission area of each of the plurality of unit pixels and exposes an area of the display panel corresponding to the non-emission area of each of the plurality of unit pixels, and

wherein the anti-reflection layer includes a plurality of stripes disposed in the first direction perpendicular to the second direction which is a bending direction and the anti-reflection layer is not disposed on the non-emission area of each of the plurality of unit pixels and is not disposed on portions of the display area of the display panel that are between pairs of the non-emission areas of the plurality of unit pixels along the first direction.

2. The flexible organic light-emitting diode display of claim 1 , wherein each of the plurality of unit pixels includes an organic light-emitting diode disposed in the emission area thereof, which includes an anode, an organic emission layer and a cathode.

3. The flexible organic light-emitting diode display of claim 2 , wherein the non-emission area includes thin film transistors for driving the organic light-emitting diode.

4. The flexible organic light-emitting diode display of claim 1 , wherein the non-emission area includes a transparent area.

5. The flexible organic light-emitting diode display of claim 2 , wherein the emission area includes thin film transistors for driving the organic light-emitting diode, disposed under the organic light-emitting diode.

6. The flexible organic light-emitting diode display of claim 1 , wherein in the second direction perpendicular to the first direction, the emission area of each of the plurality of unit pixel is located at one side thereof, and the non-emission area of each of the plurality of unit pixel is disposed at another side thereof.

7. The flexible organic light-emitting diode display of claim 6 , wherein the first direction is a horizontal direction and the second direction is vertical direction, or the first direction is a vertical direction and the second direction is a horizontal direction.

8. The flexible organic light-emitting diode display of claim 6 , wherein each of the plurality of unit pixels includes four sub-pixels located in a line in the first direction.

9. The flexible organic light-emitting diode display of claim 8 , wherein the four sub-pixels are arranged in the first direction.

10. The flexible organic light-emitting diode display of claim 8 , wherein the four sub-pixels are arranged in a 2×2 matrix.

11. The flexible organic light-emitting diode display of claim 1 , wherein each of the plurality of unit pixels includes four sub-pixels expressing red, green, blue and white.
