Color film substrate, manufacturing method thereof, OLED display panel and display apparatus

Abstract

The invention discloses a color film substrate and manufacturing method thereof, and an OLED display panel and a display apparatus. The color film substrate comprises a substrate, and a black matrix layer and a blocking mat layer sequentially arranged on the substrate in a stacked way. The blocking mat layer comprises a plurality of blocking mats arranged in the same layer. The orthographic projection of the graph of each blocking mat on the substrate is located inside the area where the graph of the black matrix layer is located. In this way, the aperture ratio of the color film substrate will not be occupied. The surface of each blocking mat is provided with an auxiliary function layer which is used for absorbing or reflecting light irradiated to surfaces of the blocking mats. Optical crosstalk among adjacent sub-pixel units on the color film substrate can be prevented. Color mixing is further prevented. The light extraction efficiency and the display contrast can be further enhanced. The display effects are also improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a color filter substrate, a manufacturing method thereof, an OLED display panel and a display device. Background technique [0002] At present, organic electroluminescent display panel (OrganicLight-EmittingDisplay, OLED) has the advantages of thinner and lighter, active light emission (no need for backlight source), no viewing angle problem, high definition, high brightness, fast response, low energy consumption, and operating temperature range. Wide, strong shock resistance, low cost, and soft display can be realized. [0003] A top-emission organic electroluminescent display panel is usually formed by boxing a color filter substrate and an array substrate with a TFT driving structure; wherein, the array substrate includes the lower half of a top-emission organic The light-emitting mode of the organic electroluminescent device can be to use RGB light-emitting materials to emi...

AI Technical Summary

Problems solved by technology

Since the material of the barrier pad is generally a material with high elastic recovery rate and high external pressure deformation resistance, such as a negative acrylic photoresist material, and a negative acrylic photoresist material is a transparent material, so the organic electroluminescent light is emitted on the top. In the type display, the light between adjacent sub-pixel units on the color filter substrate will have crosstalk, and light color mixing will occur, which will affect the display effect of the organic electroluminescent display panel.
