Abstract

The invention provides an OLED display panel and a manufacturing method thereof. The OLED display panel comprises a substrate, a thin film transistor array layer, a pixel definition layer, an organiclight-emitting layer, a packaging layer and a color film layer, the color film layer comprises a first color filter layer, a second color filter layer and a third color filter layer. The first color filter layer, the second color filter layer and the third color filter layer are sequentially stacked to form a shading part to replace a black matrix; process flow is optimized, cost of the productionequipment, the photomask and the material is greatly reduced, the risk that the luminous efficiency of the OLED device is reduced or fails after the photoetching process is reduced, the pixel definition layer also has the shading effect, and the optical effect and the bending performance of the OLED display panel can be further improved by combining the pixel definition layer with the shading part.

Description

technical field [0001] The present disclosure relates to the field of display technology, in particular to an OLED display panel and a manufacturing method thereof. Background technique [0002] Adding a polarizer (polarizer, POL) to the display panel can effectively reduce the reflectivity of the display panel under strong light, but it also has the following defects. On the one hand, the polarizer loses nearly 58% of the light output, especially for Organic Light-Emitting Diode (OLED) display panels, which greatly increases its life burden; on the other hand, due to the large thickness of the polarizer 1. The material is brittle, which is not conducive to the development of dynamic bending products. In order to develop dynamic bending products based on OLED display technology, new materials, new technologies and new processes must be introduced to replace polarizers. [0003] The technology of using color filter instead of polarizer is classified as POL-less technology, i...
