Engineering Contradiction Analysis
1Manufacturing precision
If a mask-based manufacturing process is used, then manufacturing precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent extracts the sensing line formation from the traditional mask-based multi-step process. By directly forming the sensing line on the connection electrode without requiring additional masks, the invention simplifies the manufacturing process while maintaining pattern formation precision.
Solution Approach 2:
The sensing line serves multiple functions: it acts as both a sensing element and a connection element to the connection electrode. This multi-functionality reduces the need for separate components and simplifies the overall manufacturing process.
2Reliability
If traditional sensing patterns are used, then sensing function is achieved, but light emission efficiency deteriorates
Solution Approach 1:
The patent changes the material parameter of the sensing pattern from traditional opaque materials to transparent conductive materials. This parameter change maintains the sensing function while significantly improving light emission efficiency by allowing light to pass through the sensing pattern.
Solution Approach 2:
The sensing pattern is formed using composite materials that combine conducting properties with high transparency. This allows the sensing line to maintain its electrical function while minimizing light blockage, thus improving overall light emission efficiency.
