Abstract

An OLED device is provided, including a substrate and a plurality of OLED subpixels arranged on the substrate. An insulating barrier is provided between every two adjacent OLED subpixels with different colors, and the barrier is configured to block a carrier diffusion between the two adjacent OLED subpixels. The disclosure further provides a display apparatus including the OLED device, which can prevent the light emission crosstalk between the adjacent OLED subpixels and avoid the color coordinate shift of the OLED subpixels.

First claim

What is claimed is:

1. An OLED device, comprising a substrate on which a plurality of OLED subpixels are arranged, wherein an insulating barrier is provided between every two adjacent OLED subpixels with different colors, and the barrier is configured to block a carrier diffusion between the two adjacent OLED subpixels,
wherein each of the OLED subpixels comprises an anode, a hole injection layer, a hole transport layer, an organic light-emitting layer, an electron transport layer and a cathode sequentially stacked on the substrate; the barrier is disposed on the substrate and sequentially penetrates the hole injection layer, the hole transport layer, the organic light-emitting layer, the electron transport layer and the cathode, and
wherein the barrier separates the cathodes between the two adjacent OLED subpixels with different colors, and the plurality of OLED subpixels form a plurality of OLED pixels, each of every two adjacent OLED pixels comprises four OLED subpixels, and the four OLED subpixels have three colors,
wherein among the two adjacent OLED pixels, four OLED subpixels are arranged in a rhombus, one rhombus and another adjacent rhombus share one of the OLED subpixels; and in each of the rhombuses, the two OLED subpixels with the same color are respectively located at two opposite vertexes of the rhombus; and one of the barriers is provided on each side of the rhombus, and
wherein in each of the rhombuses, two of the barriers located on opposite sides of the rhombus are connected in a straight line.

2. The OLED device according to claim 1 , wherein among the two adjacent OLED pixels, one barrier is provided between the two OLED subpixels with different colors, and a gap is provided between the two OLED subpixels having the same color.

3. The OLED device according to claim 1 , wherein among the two adjacent OLED pixels, one barrier is provided between the two OLED subpixels with different colors, and the two OLED subpixels with the same color are integrally connected.

4. The OLED device according to claim 1 , wherein among the plurality of rhombuses in the same row, each of every two adjacent straight lines has an included angle to form a wavy shape.

5. The OLED device according to claim 1 , wherein the plurality of the straight lines among the plurality of rhombuses are parallel.

6. A display apparatus, comprising the OLED device of claim 1 .

7. The display apparatus according to claim 6 , wherein among the two adjacent OLED pixels, one barrier is provided between the two OLED subpixels with different colors, and a gap is provided between the two OLED subpixels having the same color.

8. The display apparatus according to claim 6 , wherein among the two adjacent OLED pixels, one barrier is provided between the two OLED subpixels with different colors, and the two OLED subpixels with the same color are integrally connected.

9. The display apparatus according to claim 6 , wherein among the plurality of rhombuses in the same row, each of every two adjacent straight lines has an included angle to form a wavy shape.

10. The display apparatus according to claim 6 , wherein the plurality of the straight lines among the plurality of rhombuses are parallel.
