Touch Screen Display Panel Connect Component Relocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid crystal touch screens exhibit visible patterns and nonuniformity due to connect portions, leading to image quality issues.
Innovation Solution
A display panel design featuring a color filter substrate and an array substrate in a face-to-face configuration, where the white sub-pixel includes a first region for the pixel electrode and a second region sheltered by a black matrix, with the connect component between touch control lines and electrodes placed in the second region to eliminate visible patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connect components are placed in the display area to connect touch control electrodes and lines, then electrical connection is achieved, but visible patterns and image nonuniformity occur
Solution Approach 1:
The connect component is extracted from the light-emitting display area and relocated to the non-light-emitting second region of the white sub-pixel. This separation removes the harmful visible pattern effect while preserving the essential electrical connection function between touch control electrodes and lines.
Solution Approach 2:
The connect component is positioned in a different spatial dimension (the second region sheltered by black matrix) rather than in the primary display area. This dimensional relocation allows the connect component to perform its electrical function without interfering with the visual quality of the display.
2Illumination intensity
If white sub-pixel area is increased for better display, then light emission is improved, but connect component placement becomes difficult
Solution Approach 1:
The white sub-pixel is segmented into two distinct regions: a first region for light emission and a second region for connect component placement. This segmentation allows the white sub-pixel to simultaneously achieve adequate light emission area and provide space for electrical connections without increasing overall complexity.

Function Achieved in This Case
This design effectively eliminates the visible pattern phenomenon and nonuniformity, improving image quality by shielding the connect components from the light emitting direction and adjusting light emission areas for enhanced performance.
Implementation Method 1
the second region is sheltered by the black matrix from a light emitting direction of the display panel
