US 2020/0287167 A1 · Display Substrate, Method for Manufacturing the Same and Display Device

Abstract

The disclosure provides a display substrate, a method for manufacturing the same and a display device, belonging to the display technology field, to solve the problem that ultraviolet irradiation has an adverse effect on the service life of existing OLED devices. The display substrate disclosed herein includes a light processing layer which comprising a condensed-ring conjugated polymer. The light processing layer can protect the display parts below it and prevent the display parts from being exposed to ambient light and reducing their service life.

Claims18

Dependent claims

A display substrate, comprising a base substrate, a pixel layer comprising multiple sub-pixel units on a side of the base substrate, and a light processing layer comprising a condensed-ring conjugated polymer at least on a side of the pixel layer away from the base substrate,

wherein the light processing layer allows light emitted by the sub-pixel units at corresponding positions to pass through and prevents at least partially other light.

Dependencies are inferred from the claim text.
