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

This abstract first appeared for US patent application 18555566 titled 'DISPLAY SUBSTRATE AND DISPLAY DEVICE

Simplified Explanation:

The patent application describes a display substrate with sub-pixels and an isolation structure, where each sub-pixel contains a light-emitting functional layer. The isolation structure separates adjacent sub-pixels and consists of two sub-isolation structures of different sizes, with one including a protruding portion.

Key Features and Innovation:

• Display substrate with sub-pixels and isolation structure
• Light-emitting functional layers in each sub-pixel
• Two sub-isolation structures of different sizes
• Protruding portion in the second sub-isolation structure
• Slope angles of side surfaces within specific ranges
• Disconnection of at least one film layer at the isolation structure

Potential Applications: The technology can be used in various display devices such as TVs, monitors, and smartphones.

Problems Solved: The technology addresses issues related to pixel isolation and light emission in display substrates.

Benefits:

• Improved display quality
• Enhanced pixel isolation
• Better light emission efficiency

Commercial Applications: This technology has potential commercial applications in the consumer electronics industry for manufacturing high-quality display devices.

Questions about the Technology: 1. How does the size difference between the two sub-isolation structures impact display performance? 2. What are the specific benefits of the protruding portion in the second sub-isolation structure?

Frequently Updated Research: There may be ongoing research on optimizing the design of display substrates for improved performance and efficiency.

By focusing on the unique features of the technology, such as the sub-isolation structures and light-emitting functional layers, this patent application introduces a novel approach to enhancing display quality and efficiency in electronic devices.

Original Abstract Submitted
