Abstract

The invention discloses an organic light-emitting display panel and a display device. The organic light-emitting display panel comprises a substrate, a plurality of light-emitting devices and a plurality of covering layers, wherein the light-emitting devices are positioned on the substrate, any light-emitting device is used for emitting light with single color, and each light-emitting device comprises a first electrode; the covering layers are positioned on the first electrodes of the light-emitting devices, the thickness of each covering layer changes along a first direction in a tapered manner, and the first direction is parallel to the plane where the substrate is. According to the thickness of the covering layer on light extracting rate, the covering layers with different thicknesses can be set at positions with different brightness, and the thickness tapered covering layers are set in the brightness tapered direction, so that the light extracting rate in the brightness tapered direction also changes in the tapered manner, the light extracting rate at relatively low positions can be improved, the effect of brightness uniformity during watching is reached, and the display uniformity problem of the organic light-emitting display panel is solved.

Description

technical field [0001] The present invention relates to the display field, in particular, to an organic light emitting display panel and a display device. Background technique [0002] In the field of display, Organic Light-Emitting Diode (OLED) has the advantages of self-luminescence, fast response, wide viewing angle, high brightness, bright color, light and thin, etc., and thus is favored by customers. [0003] Organic light emitting display panels can be classified into PM (Passive Matrix, passive matrix driving) organic light emitting display panels and AM (Active Matrix, active matrix driving) organic light emitting display panels according to different driving methods. Organic light-emitting display panels are driven by voltage, and the voltage drop on the display panel will lead to inconsistent brightness of the entire panel, affecting the display uniformity of the panel, and then failing to meet customer requirements, thereby attracting lawsuits from customers.
