Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of signal lines around holes in display panels, particularly in full active screens, affects the display effect and increases wiring difficulty due to the need for multiple windings and bezel sealing adhesive transmittance, impacting product yield and user requirements.
Innovation Solution
A display substrate design with first and second signal lines on opposite sides of a hole, grouped switch units, and connection lines that reduce the number of lines around the hole by using third connection lines to combine signals, allowing fewer lines to be wound around the hole, improving transmittance and display effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple signal lines are wound around the hole to maintain signal transmission, then the wiring completeness is ensured, but the display effect deteriorates due to reduced transmittance of bezel sealing adhesive and increased wiring complexity
Solution Approach 1:
The signal lines are segmented into two groups: first signal lines that pass through the hole region and second signal lines that are wound around the hole. This segmentation allows different signal transmission paths to be optimized independently, reducing overall wiring complexity while maintaining signal completeness.
Solution Approach 2:
The patent introduces a vertical dimension by routing first signal lines through the hole region in the vertical direction, rather than only winding them horizontally around the hole. This dimensional change reduces the number of windings needed and simplifies the wiring layout around the hole.
2Reliability
If multiple signal lines are wound around the hole to ensure signal transmission, then the wiring completeness is maintained, but the transmittance of bezel sealing adhesive deteriorates affecting display effect
Solution Approach 1:
Signal lines are divided into first signal lines that pass through the hole region and second signal lines that wind around it. This segmentation reduces the number of lines winding around the hole, minimizing obstruction to light and improving the transmittance of the bezel sealing adhesive in the display area.
Solution Approach 2:
By routing first signal lines through the hole region in the vertical direction, the patent reduces the horizontal winding count around the hole. This dimensional change directly improves light transmittance in the bezel sealing adhesive area while maintaining signal transmission through alternative paths.
3Reliability
If multiple signal lines are wound around the hole to maintain wiring completeness, then signal transmission is ensured, but the product yield deteriorates due to increased wiring difficulty
Solution Approach 1:
The wiring structure is segmented into first signal lines passing through the hole and second signal lines winding around it. This segmentation simplifies the overall wiring process by reducing the number of complex windings required, thereby improving manufacturing efficiency and product yield.
Solution Approach 2:
The patent utilizes the vertical dimension by routing first signal lines through the hole region, which simplifies the horizontal wiring layout and reduces wiring complexity. This dimensional approach makes the manufacturing process easier and improves product yield by reducing wiring difficulties.
