Abstract

Organic light-emitting displays and methods of manufacturing the same are disclosed. An organic light-emitting display includes a substrate; a display panel provided on the substrate, the display panel having an emission area in which an organic light-emitting device is provided and a non-emission area that separates the emission area; and a color-changing material layer provided on the display panel, wherein the color-changing material layer includes a light-transmission part corresponding to the emission area and a light-blocking part corresponding to the non-emission area.

Claims (39)

1. An organic light-emitting display comprising:

a substrate;

a pixel defining layer having an aperture disposed on substrate;

a display panel provided on the substrate, the display panel including an emission area and a non-emission area that separates the emission area by the pixel defining layer; and

a color-changing material layer provided on the display panel,

wherein the color-changing material layer comprises a light-transmission part corresponding to the emission area and a light-blocking part corresponding to the non-emission area.

2. The organic light-emitting display of claim 1 , wherein the color-changing material layer has a light transmissivity that irreversibly changes in response to ultraviolet rays irradiation.

3. The organic light-emitting display of claim 1 , wherein the color-changing material layer has a light transmissivity that irreversibly changes in response to a temperature between about 80° C. and about 100° C.

4. The organic light-emitting display of claim 1 , further comprising an ultraviolet blocking layer on the color-changing material layer.

5. The organic light-emitting display of claim 1 , further comprising:

a thin film encapsulation for sealing up the display panel; and

an external light reflection preventing layer on the thin film encapsulation,

wherein the color-changing material layer is disposed on the external light reflection preventing layer.

6. The organic light-emitting display of claim 1 , wherein the color-changing material layer comprises at least one material selected from the group consisting of diarylethene derivatives, naphthopyran derivatives, polyurethanes, spirobenzopyran compounds, and spiroxazine compounds.

7. The organic light-emitting display of claim 1 , further comprising a thin film encapsulation for sealing up the display panel.

8. The organic light-emitting display of claim 7 , wherein the thin film encapsulation comprises at least one organic layer or at least one organic layer and at least one inorganic layer, wherein the color-changing material layer is included in the thin film encapsulation.

9. The organic light-emitting display of claim 1 , further comprising an external light reflection preventing layer formed on the display panel.

10. The organic light-emitting display of claim 9 , wherein the external light reflection preventing layer comprises at least one semi-transmissive metal layer and at least one dielectric layer.

11. The organic light-emitting display of claim 1 , further comprising:

a sealing substrate for sealing up the display panel; and

a sealing member for bonding the substrate and the sealing substrate.

12. The organic light-emitting display of claim 11 , wherein the color-changing material layer is disposed on an upper or a lower surface of the sealing substrate.

13. A method of manufacturing an organic light-emitting display, the method comprising:

forming a display panel on a substrate, the display panel including an emission area defined by an aperture of a pixel defining layer and a non-emission area that separates the emission area by the pixel defining layer; and

forming a color-changing material layer on the display panel, the color-changing material layer including a light-transmission part and a light-blocking part,

wherein the light-transmission part corresponds to the emission area, and the light-blocking part corresponds to the non-emission area.

14. The method of claim 13 , wherein the forming of the color-changing material layer comprises:

forming a pre-color-changing material layer on the display panel; and

irradiating ultraviolet rays on a selective region of the pre-color-changing material layer.

15. The method of claim 13 , wherein the forming of the color-changing material layer, comprises:

forming a pre-color-changing material layer on the display panel; and

applying heat to a selective region of the pre-color-changing material layer.

16. The method of claim 13 , further comprising forming a thin film encapsulation for sealing up the display panel,

wherein the forming of the color-changing material layer is included in the forming of the thin film encapsulation.

17. The method of claim 13 , further comprising forming an ultraviolet blocking layer on the color-changing material layer.

18. The method of claim 13 , further comprising bonding a sealing substrate for sealing up the display panel and the substrate,

wherein the color-changing material layer is formed on the sealing substrate

19. The method of claim 13 , further comprising forming an external light reflection preventing layer on the display panel.

20. The method of claim 19 , wherein the external light reflection preventing layer comprises at least one semi-transmissive metal layer and at least one dielectric layer.
