DISPLAY PANEL AND DISPLAY DEVICE Russian patent published in 2022 - IPC G09G3/3208 

FIELD: display technology.

SUBSTANCE: invention relates to display panels and display devices. The result is achieved by the fact that the display panel includes the first color sub-pixel, the second color sub-pixel and a pixel-bounding layer. The pixel-bounding layer includes many holes, the first color sub-pixel includes the first effective light-emitting region, the second color sub-pixel includes the second effective light-emitting region, the area of the second effective light-emitting region is smaller than the area of the first effective light-emitting region. The first color sub-pixels include the first color light-emitting layer located in the hole and on the pixel-bounding layer, the second color sub-pixels include the second color light-emitting layer located in the hole and on the pixel-bounding layer, and the ratio of the areas between the orthogonal projections of the first color light-emitting layer and the first effective light-emitting region on the base substrate is less, than is the ratio of the areas between the orthogonal projections of the second color light-emitting layer and the second effective light-emitting region on the base substrate. In the embodiment of the present disclosure, the area ratios between the light-emitting layers and the effective light-emitting regions of the various colored sub-pixels are different to ensure that the deviation caused by the evaporation process was more balanced for each sub-pixel.

EFFECT: increase in the display quality of organic light-emitting display devices.
