Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the touch control signal line and wire overlap in the fan-shaped wire area to realize signal transmission, then the touch control function is achieved, but signal interference such as noise occurs between the touch control signal line and the wire
Solution Approach 1:
The overlapping area between the touch control signal line and wire is segmented by introducing hollow parts that divide the continuous overlapping region into separate sections, reducing the total area of overlap and thereby minimizing signal interference while maintaining necessary signal transmission pathways
Solution Approach 2:
The hollow parts are strategically positioned at specific locations within the overlapping area to create local variations in the structure. This local modification reduces the overlapping area precisely where signal interference occurs most severely, while preserving the overall signal transmission functionality in other regions
2Object-affected harmful factors
If the overlapping area between the touch control signal line and wire is reduced by adding hollow parts, then signal interference is decreased, but the structural complexity of the wire or signal line increases
Solution Approach 1:
The hollow parts create a porous or perforated structure in the overlapping area, which reduces the material presence and thereby reduces signal interference. This porous approach achieves the interference reduction goal while maintaining a relatively simple manufacturing process compared to more complex structural modifications

AI summary
A touch control display panel and a touch control display device are provided. In the touch control display panel, an area of an overlapping area between a touch control signal line and a wire can be reduced. Therefore, signal interference between the touch control signal line and the wire is reduced, and display performance and touch control performance of the touch control display panel are in turn enhanced.
