Touch Display Panel Uniform Lead Line Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In touch display panels, non-uniform distribution of lead lines results in non-uniform image display when the image shape is abnormal, affecting user experience and image quality.
Innovation Solution
The touch display panel design includes lead lines arranged uniformly across the display area, with each touch electrode column having a different number of electrodes, ensuring equal connectivity and uniform signal interference, allowing for uniform image display even in abnormal shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display area is changed to an abnormal shape to accommodate cameras and other components, then the adaptability of the display product is improved, but the uniform distribution of lead lines cannot be maintained, resulting in non-uniform image display
Solution Approach 1:
The patent applies local quality by differentiating the connection configuration between first touch electrode columns and second touch electrode columns. First touch electrode columns (with more electrodes) connect to multiple lead lines, while second touch electrode columns (with fewer electrodes) connect to fewer lead lines. This localized differentiation allows the lead lines to be uniformly distributed across the entire display area, ensuring uniform image display while accommodating abnormal display shapes for cameras and other components.
2Adaptability or versatility
If touch electrode columns have different quantities of electrodes to accommodate abnormal display shapes, then the adaptability is improved, but the lead line distribution becomes non-uniform, affecting image quality
Solution Approach 1:
The patent implements local quality by creating different connection configurations for different regions. Touch electrode columns with more electrodes (first touch electrode columns) are connected to multiple lead lines, while touch electrode columns with fewer electrodes (second touch electrode columns) are connected to fewer lead lines. This localized adaptation ensures that each region's electrode column is properly connected according to its specific electrode count, maintaining reliable image display quality while supporting abnormal display shapes.
Solution Approach 2:
The patent applies dynamics by making the lead line connection configuration flexible and adaptive rather than fixed. The connection between touch electrode columns and lead lines dynamically adjusts based on the number of electrodes in each column. This dynamic configuration allows the display to maintain uniform image quality while adapting to various abnormal shapes required for accommodating cameras and other components.
3Manufacturing precision
If lead lines are arranged uniformly across the display area, then the image display uniformity is improved, but it becomes difficult to connect touch electrodes in abnormal shape configurations
Solution Approach 1:
The patent resolves this contradiction by applying local quality - lead lines are uniformly distributed across the entire display area, but the connection configuration varies locally. Each touch electrode column connects to a number of lead lines proportional to its electrode count. This approach maintains uniform lead line distribution for consistent image display while enabling flexible connectivity for abnormal shape configurations through localized connection variations.
