Patterned Grid Layer Layout to Reduce Visual Dark Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices often exhibit inconsistencies in transmittance and poor appearance due to visual dark lines, such as concentric circle patterns, which affect their reliability and quality.
Innovation Solution
The electronic device incorporates a first substrate with a first pattern layer featuring interconnected first and second grid regions, where one grid is metal and the other is non-metal, to reduce visual dark lines and enhance appearance by adjusting transmittance and brightness through varying line widths, areas, and shapes of the grids.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single-type grid pattern is used, then the manufacturing process is simple, but visual dark lines and transmittance inconsistency occur
Solution Approach 1:
The patent applies local quality by differentiating grid materials in different regions: the first grid region uses a first material while the second grid region uses a second material with different optical properties. This local differentiation eliminates visual dark lines and transmittance inconsistency without complicating the overall manufacturing process, as each region is still formed using standard deposition techniques.
Solution Approach 2:
The patent employs composite materials by combining different grid materials (first material and second material) in the same pattern layer. This composite approach allows optimization of optical properties in different areas, resolving the appearance quality issue while maintaining manufacturing feasibility through sequential deposition processes.
2Ease of manufacture
If uniform grid lines are used, then the pattern is simple to fabricate, but visual dark lines and poor appearance result
Solution Approach 1:
The patent implements local quality by assigning different materials with different optical characteristics to different grid regions. The first grid region's material and the second grid region's material are specifically selected to achieve uniform transmittance across the entire pattern, eliminating visual dark lines while preserving fabrication simplicity.
3Device complexity
If a single material is used for all grids, then the device structure is simple, but visual dark lines and concentric circle patterns appear
Solution Approach 1:
The patent resolves the appearance consistency issue by introducing composite materials: the first grid region uses a first material while the second grid region uses a second material. This material differentiation eliminates visual dark lines and concentric circle patterns. The structural complexity increase is minimal, as the composite material approach integrates seamlessly into existing multi-layer device architectures.
