Abstract

An organic light emitting display panel and a display device are disclosed, which alleviate or eliminate the phenomena of colored edges and stripes, and reduce the effect of an over fuzzy pattern edge. The organic light emitting display panel includes a substrate, and pixels, which are formed on the substrate by an evaporation mask plate, and each of which is provided with an organic light emitting diode. The organic light emitting display panel further includes a TFE layer on the organic light emitting diode, a flexible blocking layer above the TFE layer, and at least a light diffuse layer between the flexible blocking layer and the organic light emitting diode.

Claims (17)

1. An organic light emitting display panel comprising:

a substrate;

a plurality of pixels formed on the substrate by an evaporation mask plate and spaced apart by inter-pixel regions, comprising respective organic light emitting diodes;

a flexible blocking layer arranged on a same side of the organic light emitting diodes away from the substrate, wherein the flexible blocking layer is continuous and flexible, and covers the plurality of pixels and the inter-pixel regions between the plurality of pixels; and

a TFE layer and at least one light diffuse layer arranged between the organic light emitting diodes and the flexible blocking layer, wherein the at least one light diffuse layer is continuous and covers the plurality of pixels and the inter-pixel regions between the plurality of pixels;

wherein the TFE layer comprises stacked films, the stacked films comprise alternately arranged organic films and inorganic films, and the at least one light diffuse layer is arranged between two neighboring ones of the stacked films.

2. The organic light emitting display panel of claim 1 , wherein the at least one light diffuse layer comprises a plurality of the light diffuse layers arranged among multiple neighboring ones of the stacked films.

3. The organic light emitting display panel of claim 1 , further comprising a light diffuse layer arranged between the organic light emitting diodes and the TFE layer.

4. The organic light emitting display panel of claim 1 , further comprising a light diffuse layer arranged between the TFE layer and the flexible blocking layer and another light diffuse layer arranged between the organic light emitting diodes and the TFE layer.

5. The organic light emitting display panel of claim 1 , further comprising a light diffuse layer arranged on the flexible blocking layer.

6. The organic light emitting display panel of claim 1 , wherein the light diffuse layer is distributed across the organic light emitting diodes of the plurality of pixels.

7. The organic light emitting display panel of claim 6 , wherein the light diffuse layer is a glue layer comprising light diffuse particles.

8. The organic light emitting display panel of claim 6 , wherein the light diffuse layer is a film comprising concave and convex shapes of different heights and is formed by imprinting.

9. A display device, comprising the organic light emitting display panel of claim 1 .

10. The organic light emitting display panel of claim 2 , further comprising a light diffuse layer arranged on the flexible blocking layer.

11. The organic light emitting display panel of claim 3 , further comprising a light diffuse layer arranged on the flexible blocking layer.

12. The organic light emitting display panel of claim 4 , further comprising a light diffuse layer arranged on the flexible blocking layer.
