Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If installation holes are provided in the touch display panel for camera openings, then the display functionality is enhanced, but the completeness of touch electrodes and connection bridges is disrupted, affecting touch performance
Solution Approach 1:
The connection bridge is divided into multiple segments: a first connection line in the second conductive layer, and a second connection line in the first conductive layer that passes through the insulating layer. This segmentation allows the electrical connection to bypass the installation hole area, maintaining touch electrode completeness while accommodating camera openings.
Solution Approach 2:
The connection path transitions from a single-layer planar connection to a multi-layer three-dimensional structure. The second connection line passes through the insulating layer from the first conductive layer to the second conductive layer, creating a vertical connection path that avoids the disruption caused by installation holes in the horizontal plane.
2Reliability
If touch electrodes are made complete without installation holes, then touch performance is maintained, but camera openings cannot be provided in the display panel
Solution Approach 1:
The connection bridge is segmented into multiple parts across different conductive layers. The first connection line remains in the second conductive layer while the second connection line extends into the first conductive layer, allowing the touch electrode to remain complete while accommodating camera openings through the multi-layer structure.
Solution Approach 2:
The connection structure is nested across multiple conductive layers. The first connection line in the second conductive layer is nested with the second connection line in the first conductive layer, creating a hierarchical structure that maintains touch electrode integrity while providing space for camera openings.
3Ease of manufacture
If connection bridges are simplified to reduce manufacturing complexity, then ease of manufacture is improved, but electrical connectivity around installation holes cannot be maintained
Solution Approach 1:
The connection bridge is segmented into standardized parts: a first connection line in the second conductive layer and a second connection line in the first conductive layer. This segmentation allows each part to be manufactured using standard processes while ensuring reliable electrical connectivity around installation holes through their combined multi-layer structure.

AI summary
A touch structure includes: a first conductive layer, an insulating layer and a second conductive layer that are sequentially stacked. The second conductive layer includes touch electrodes and touch lines. The touch structure includes: a first connection line and two second connection lines that are located in the second conductive layer, and a connection pattern located in the first conductive layer. The two second connection lines are arranged at two sides of the first connection line, respectively. The connection pattern crosses the first connection line, and passes through the insulating layer to be connected to the two second connection lines. For a portion of the connection pattern located between the first connection line and a second connection line, a length of a contour from the first connection line to the second connection line is greater than a distance between the first connection line and the second connection line.
