Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current touch panel technologies face challenges in reducing manufacturing costs and achieving low visibility of conductive micropatterns, which require complex processes to adjust tilt angles and geometric forms, resulting in higher workloads and costs.
Innovation Solution
A touch panel design featuring a transparent substrate with overlapping first and second conductive micropatterns, where each cell has inconsistent transmittance due to varying thickness, surface roughness, crystalline form, or affixed films, reducing the visibility of the micropattern by minimizing contrast between traces and combination cells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the tilt angle between traces is adjusted to enhance visibility, then the visibility of the micropattern is improved, but the manufacturing complexity and cost increase
Solution Approach 1:
The patent changes the parameter of trace tilt angle to control the visibility of the micropattern. By adjusting the tilt angle between the first and second conductive micropattern traces, the contrast and visibility are enhanced without changing the geometric form or size of cells, thereby simplifying the manufacturing process while achieving the desired visibility improvement.
2Illumination intensity
If different geometric forms and sizes are designed in micropattern to reduce visibility, then the visibility is reduced, but the manufacturing workload and cost increase
Solution Approach 1:
The patent uses parameter changes by adjusting the tilt angle of the traces to control micropattern visibility. This approach avoids the need to design different geometric forms or sizes for cells, which would increase manufacturing complexity. Instead, the same geometric form is used with varying tilt angles to achieve visibility control, thereby maintaining ease of manufacture.
3Ease of manufacture
If the same shape and size of conductive micropattern are used, then the manufacturing complexity is reduced, but the visibility control becomes difficult
Solution Approach 1:
The patent resolves this contradiction by changing the tilt angle parameter of the conductive micropattern traces. This allows the same shape and size patterns to be used while achieving effective visibility control through the angular orientation of the traces, thereby maintaining both manufacturing ease and visibility control capability.

Function Achieved in This Case
