DISPLAY SUBSTRATE AND DISPLAY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17800045 titled 'DISPLAY SUBSTRATE AND DISPLAY DEVICE

Simplified Explanation

The display substrate described in the patent application has multiple sub-pixels and includes various layers such as a base substrate, a driving circuit layer, a pixel definition layer, a light-emitting device layer, and a black matrix layer. Each sub-pixel consists of a pixel driving circuit and a light-emitting device. The black matrix layer has openings that expose the light-emitting devices, while the pixel definition layer has sub-pixel openings that overlap with the openings in the black matrix layer.

• The display substrate includes a base substrate, driving circuit layer, pixel definition layer, light-emitting device layer, and black matrix layer.
• Each sub-pixel contains a pixel driving circuit and a light-emitting device.
• The black matrix layer has openings that expose the light-emitting devices, while the pixel definition layer has sub-pixel openings that overlap with the openings in the black matrix layer.

Original Abstract Submitted

A display substrate and a display device are disclosed, and the display substrate has a plurality of sub-pixels, and includes a base substrate, a driving circuit layer, a pixel definition layer and a light-emitting device layer, and a black matrix layer. Each sub-pixel includes a pixel driving circuit in the driving circuit layer and a light-emitting device in the light-emitting device layer. The black matrix layer includes a plurality of first light-transmitting openings respectively exposing the light-emitting devices of the plurality of sub-pixels in a direction perpendicular to a surface of the base substrate. The pixel definition layer includes a plurality of sub-pixel openings, at least part of the plurality of sub-pixel openings are in one-to-one correspondence with and at least partially overlapped with the plurality of first light-transmitting openings, and at least one of the plurality of first light-transmitting openings has an arc-shaped edge.
