Problems solved by technology

[0002] For organic light-emitting (OLED) display panels, the light-emitting layers of sub-pixels (R / G / B) of different colors need to evaporate the light-emitting materials to the openings of the pixel definition layer (PDL) through the evaporation mask (Mask). Due to the limitation of the openings of the mask (Mask) and the distance between the openings, the current pixel arrangement cannot correspond to the realization of the stretching mask production and evaporation process of high pixel density (PPI) products.

Abstract

The embodiment of the invention provides pixel arrangement of an organic light-emitting display panel. The pixel arrangement of the organic light-emitting display panel comprises repetitive units arranged in an array mode. The repetitive units comprise a first pixel row to a sixth pixel column, wherein the first pixel column comprises a first sub-pixel located in an i-th pixel row and a second sub-pixel located in an (i+2)-th pixel row; the second pixel column comprises a third sub-pixel located in a j-th pixel row and a (j+2)-th pixel row; the third pixel column comprises a second sub-pixel located in an i-th pixel row and a first sub-pixel located in the (i+2)-th pixel row; the fourth pixel column comprises a second sub-pixel located in a j-th pixel row and a first sub-pixel located in a(j+2)-th pixel row; the fifth pixel column comprises a third sub-pixel located in an i-th pixel row and an (i+2)-th pixel row; the sixth pixel column comprises a first sub-pixel located in an j-th pixel row and a second sub-pixel located in a (j+2)-th pixel row, wherein i = 1, j = 2, or j = 1, i = 2. According to the scheme, the evaporation color mixing risk can be reduced, the mask plate manufacturing difficulty is reduced, the aperture opening ratio is increased, and the color edge phenomenon can be improved.

Description

【Technical field】 [0001] The present invention relates to the field of display technology, in particular to a pixel arrangement of an organic light emitting display panel and the organic light emitting display panel. 【Background technique】 [0002] For organic light-emitting (OLED) display panels, the light-emitting layers of sub-pixels (R / G / B) of different colors need to evaporate the light-emitting materials to the openings of the pixel definition layer (PDL) through the evaporation mask (Mask). Due to the limitation of the opening of the mask (Mask) and the distance between the openings, the current pixel arrangement cannot correspond to the realization of the stretching mask production and evaporation process of high pixel density (PPI) products. 【Content of invention】 [0003] In view of this, an embodiment of the present invention provides a pixel arrangement of an organic light emitting display panel and an organic light emitting display panel to solve the above tec...
