Display Panel Zigzag Branch Structure Reduces Dark Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display panels exhibit a large width of dark lines due to the arrangement of first and second branches around a linear backbone, leading to poor display quality.
Innovation Solution
The display panel features pixel units with first and second domains, where first branches and second branches are staggered to form a zigzag structure between domains, with specific angles and intervals that reduce dark lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If first branches and second branches are symmetrically disposed around a linear backbone, then the structure is simple and easy to manufacture, but the width of dark lines becomes large resulting in poor display quality
Solution Approach 1:
The patent applies asymmetry by disposing first branches and second branches at different angles relative to the backbone (first angle and second angle that are not equal), breaking the symmetric arrangement. This asymmetric configuration reduces the width of dark lines at the linear backbone while maintaining manufacturing feasibility, directly resolving the contradiction between structural simplicity and dark line width control
2Manufacturing precision
If first branches and second branches are staggered to form a zigzag structure, then display quality improves by reducing dark lines, but the structure becomes more complex
Solution Approach 1:
The patent applies segmentation by dividing the pixel electrode into multiple first branches and second branches that are staggered relative to each other, forming a zigzag structure. This segmentation approach reduces dark line width by creating alternating patterns that disrupt continuous dark line formation, while the regular staggering pattern keeps the complexity manageable through repetitive modular units
3Manufacturing precision
If the number of first branches and second branches is increased, then the zigzag structure becomes more effective at reducing dark lines, but the manufacturing process becomes more difficult
Solution Approach 1:
The patent applies parameter changes by optimizing the number of first branches and second branches, their angles, and intervals to achieve effective dark line reduction. By carefully selecting specific parameter values (angles, intervals, branch counts), the patent balances the effectiveness of dark line reduction with the feasibility of manufacturing processes
