DISPLAY SUBSTRATE AND MANUFACTURING METHOD THEREFOR, AND DISPLAY DEVICE

The display substrate described in the patent application includes sub-pixels with a light-emitting function layer and an isolation portion with specific shapes and angles to improve performance.

The display substrate includes a base substrate, sub-pixels, and an isolation portion.
Each sub-pixel has a light-emitting function layer.
The isolation portion consists of a first sub-isolation portion and a second sub-isolation portion.
The second sub-isolation portion has a protrusion that varies in shape depending on the adjacent sub-pixel.
The slope angle between the side surface of the isolation portion and the base substrate is between 60° to 120°.
At least one film of the light-emitting function layer is disconnected at the isolation portion.

Potential Applications

The technology described in the patent application could be used in the manufacturing of high-quality display devices such as OLED screens for smartphones, tablets, TVs, and other electronic devices.

Problems Solved

This technology solves the problem of improving the performance and efficiency of display substrates by optimizing the design of the isolation portion to enhance the functionality of the sub-pixels.

Benefits

What are the potential cost implications of implementing this technology in the manufacturing process of display devices?

The patent application focuses on the technical aspects of the display substrate design, but it does not address the potential cost implications of incorporating this technology into the manufacturing process.

Original Abstract Submitted

A display substrate, a manufacturing method therefor, and a display device are provided. The display substrate includes a base substrate, sub-pixels and an isolation portion, and each sub-pixel includes a light-emitting function layer. The isolation portion includes a first sub-isolation portion and a second sub-isolation portion. The first sub-isolation portion is between the second sub-isolation portion and the base substrate. The second sub-isolation portion includes a protrusion protruding relative to an edge of the first sub-isolation portion, the second sub-isolation portion facing one of adjacent sub-pixels is different in shape from the second sub-isolation portion facing the other one; or, a slope angle between a side surface of the first sub-isolation portion or the second sub-isolation portion facing one sub-pixel and a plane parallel to the base substrate is 60° to 120°. At least one film of the light-emitting function layer is disconnected at the isolation portion.
