Array Substrate Anti-Static Layout for Narrow-Bezel Special-Shaped Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies face challenges in achieving narrow bezel designs for special-shaped display panels, particularly in rounded corners, due to increased wiring space requirements for gate and data lines, which hinder the implementation of narrow bezels.
Innovation Solution
The array substrate design includes gate lines extending in one direction and data lines extending in another direction, with anti-static structures in bezel areas that extend directionally or in winding directions to minimize space, and features like floating anti-static structures and short circuit rings to manage static electricity, allowing for reduced bezel widths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If gate lines and data lines are extended to cover the display area and bezel area, then signal coverage is improved, but wiring space requirements increase causing bezel width to increase
Solution Approach 1:
The patent introduces anti-static structures that extend in the second direction (winding direction of data lines) to manage static electricity, allowing gate lines and data lines to be arranged more efficiently in the first direction. This dimensional approach enables better signal coverage while reducing the space required in the bezel area, thus narrowing the bezel width.
Solution Approach 2:
The patent divides the bezel area into first bezel area and second bezel area, with anti-static structures segmented into first anti-static structures and second anti-static structures. This segmentation allows for optimized wiring arrangements in different regions, enabling narrow bezel design while maintaining signal coverage and anti-static functionality.
2Reliability
If anti-static structures are added to manage static electricity, then anti-static capability is improved, but wiring space requirements increase
Solution Approach 1:
The anti-static structures are configured to extend in the second direction (winding direction of data lines) rather than occupying significant area in the first direction. This dimensional arrangement provides effective anti-static capability while minimizing the impact on wiring space for gate lines and data lines.
Solution Approach 2:
The patent combines anti-static functionality with the existing wiring structure by integrating anti-static structures into the bezel area arrangement. The first and second anti-static structures are merged with the gate line and data line arrangements, allowing anti-static capability to be achieved without requiring separate, additional wiring space.
