Display Panel Centerline Gate Drive Layout for Uniform Charging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display panels face challenges in achieving borderless designs due to the limitations of gate drive circuits being confined to the edge display area, leading to signal delay, voltage drop, and poor display uniformity as the number of gate drive circuits increases.
Innovation Solution
The display panel design disperses gate drive circuits on both sides of a center line within the display area, allowing sufficient space for multiple gate drive circuits, reducing signal transmission distances, and improving display uniformity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If gate drive circuits are confined to the edge display area, then the display panel structure is simple, but signal transmission distance increases causing delay and voltage drop
Solution Approach 1:
The gate drive circuits are segmented and distributed on both sides of the center line within the display area, rather than being concentrated at the edge. This segmentation reduces the maximum signal transmission distance from spanning the entire panel width to covering only half the width at most, thereby reducing signal delay and voltage drop while maintaining structural simplicity.
2Manufacturing precision
If multiple gate drive circuits are added to improve driving performance, then display uniformity improves, but the number of circuits increases causing more voltage drop
Solution Approach 1:
Gate drive circuits are strategically positioned at specific locations on both sides of the center line within the display area. This local placement optimizes the distribution of driving signals across different regions of the display panel, ensuring uniform driving performance while minimizing the number of circuits needed and reducing overall voltage drop.
