Display Panel Semiconductor Layer Spacing for Brightness Uniformity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display panels experience uneven display brightness due to regional characteristic differences in transistor characteristics caused by varying lengths of semiconductor layers, which are interconnected as a semiconductor layer unit, leading to non-uniform brightness across the display area.
Innovation Solution
The display panel features semiconductor layers of adjacent pixel circuits spaced apart from each other, both in the first and second directions, reducing regional characteristic differences and ensuring uniform transistor characteristics, with interconnecting structures in conductive layers improving wiring rationality and brightness uniformity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If semiconductor layers of adjacent pixel circuits are interconnected as a semiconductor layer unit, then device complexity is reduced, but manufacturing precision deteriorates due to varying lengths causing regional characteristic differences in transistor characteristics
Solution Approach 1:
The semiconductor layers of adjacent pixel circuits are divided and spaced apart rather than interconnected as a single unit. This segmentation ensures that each pixel circuit has its own independent semiconductor layer with consistent length, eliminating regional characteristic differences while maintaining manageable device complexity through standardized repeating units.
2Manufacturing precision
If semiconductor layers are spaced apart from each other, then manufacturing precision is improved by reducing regional characteristic differences, but device complexity increases due to additional spacing structures
Solution Approach 1:
The spacing between semiconductor layers is applied locally at specific positions where regional characteristic differences occur, rather than uniformly throughout the entire display panel. This targeted approach improves transistor characteristic uniformity where needed while minimizing the overall structural complexity increase.
3Device complexity
If interconnecting structures are arranged in the same layer as preset signal lines, then device complexity is reduced, but manufacturing precision deteriorates due to wiring pressure affecting brightness uniformity
Solution Approach 1:
The interconnecting structures are arranged in a different layer from the preset signal lines, separating them in the vertical dimension. This layering approach eliminates wiring pressure issues that would affect brightness uniformity while maintaining wiring efficiency through optimized inter-layer connections.
