Abstract

The invention discloses an OLED display panel and a manufacturing method therefor. The OLED display panel comprises a substrate and a plurality of pixel units arranged on the substrate; each pixel unit comprises a plurality of sub pixel units, wherein the sub pixel units comprises light emitting layers and light extraction layers which are arranged in a stacked manner; and in the pixel units, the thicknesses of the light extraction layers corresponding to different sub pixel units are different, so that the difference value of brightness decay proportions, changed along with observation angles, of the light from different sub pixel units can be smaller than a set threshold value. By virtue of the way, the brightness decay proportions of the sub pixels of different colors can be kept consistent, so as to reduce color deviation of displayed images.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED display panel and a manufacturing method thereof. Background technique [0002] Organic light-emitting diode (Organic Light-Emitting Diode, UIV OLED) is also called organic electroluminescence display, organic light-emitting semiconductor (Organic Electroluminescence Display, UIV OLED). Due to its characteristics such as self-illumination, high contrast, wide color gamut, fast response, and low power consumption, it has been more and more widely researched and applied; its light and thin, flexible and other characteristics have expanded its application fields and brought greater business opportunities. [0003] However, as the area of ​​the OLED display panel increases, as the viewing angle changes, the brightness attenuation ratios of the R / G / B three colors are inconsistent, which will lead to an increase in the color shift in the white state.
