Problems solved by technology

[0006] However, the existing display panels using the microcavity structure can only display monochromatic light. Due to the low brightness of monochromatic light, this not only affects the display effect of the display panel, but also leads to high power consumption of the display panel.

Abstract

The invention provides a pixel unit structure, an organic light emitting display panel and a display device. The pixel unit structure comprises a plurality of sub pixels comprising organic light emitting layers emitting white light; multi color display is performed through the pixel unit structure by the micro cavity effect; one variety of the sub pixels is used for displaying one color; the pixel unit structure comprises white sub pixels; the ratio of the length of the micro cavities corresponding to the white sub pixels and the length of the micro cavity of a first sub pixel is not smaller than three; the length of the micro cavity of the first sub pixel is larger than that corresponding to the other sub pixels except for the white sub pixels. Thus, white main color display can be implemented, and high display precision and low energy consumption are provided.

Description

technical field [0001] The present invention relates to the field of display technology, and specifically relates to a pixel unit structure, an organic light-emitting display panel and a display device. Background technique [0002] At present, active-matrix organic light emitting diode (AMOLED: Active-matrix organic light emitting diode) display panels still use fine metal mask (FMM: Fine Metal Mask) technology in the mass production process, and pixel juxtaposition method (RGB side by side), to achieve full mining. [0003] However, there are many problems in the fine metal mask technology, such as the production and cleaning of the mask, alignment and expansion during the process, which make the color mixing of the display panel serious, resulting in a low production yield of the display panel and high manufacturing costs. [0004] In order to solve the full-color problem of the fine metal mask technology, another technical solution in the prior art is to use a white org...
