Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies face challenges in minimizing the frame width of profiled display products due to inefficient layout and placement of electrostatic discharge circuits and loading compensation structures in the peripheral regions, leading to non-uniform loading and display quality issues.
Innovation Solution
A display substrate with a peripheral region that includes a bonding region and a profiled region, featuring compensation scanning lines, data lines, an electrostatic discharge circuit, and a loading compensation structure, where the electrostatic discharge circuit is positioned between the display region and the loading compensation structure, and the common signal line serves as the loading compensation structure, optimizing the layout to reduce frame width and ensure loading uniformity.

1Length of stationary object
If the electrostatic discharge circuit and loading compensation structure are arranged in the peripheral region, then the frame width can be reduced, but the layout complexity and difficulty of achieving uniform loading increase
Solution Approach 1:
The peripheral region is divided into a bonding region and a profiled region, with the profiled region further containing the electrostatic discharge circuit and loading compensation structure as separate functional modules. This segmentation allows each component to be independently optimized and arranged, reducing overall layout complexity while minimizing frame width.
Solution Approach 2:
The electrostatic discharge circuit is positioned between the display region and the loading compensation structure, creating a multi-dimensional spatial arrangement. This dimensional optimization allows efficient use of the profiled region space, reducing frame width without increasing layout complexity.
2Stability of the object's composition
If the electrostatic discharge circuit is positioned between the display region and loading compensation structure, then loading uniformity is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The profiled region is designed with specific local characteristics to accommodate the electrostatic discharge circuit and loading compensation structure. This localized structural optimization ensures proper positioning and function while reducing overall manufacturing precision requirements through gradual transitions and standardized interfaces.
