Touch Substrate Electrode Hollowed-Out Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Touch substrates with electrode patterns made of indium tin oxide (ITO) reflect light, causing visual differences between covered and uncovered regions, which degrades the display effect and user experience in light environments.
Innovation Solution
The touch substrate incorporates electrodes with a hollowed-out structure, creating non-reflecting regions among the reflecting areas, reducing the visual distinction between electrode pattern-covered and uncovered areas, thereby enhancing display quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrode patterns are completely covered with transparent conducting material, then electrode functionality is ensured, but light reflection creates visual differences that degrade display effect
Solution Approach 1:
The electrode pattern is segmented into multiple regions, with some regions covered by transparent conducting material and others left uncovered. This segmentation allows the electrode to maintain functionality while creating non-reflecting areas that reduce visual perception of the electrode pattern, thereby improving display effect.
Solution Approach 2:
Different regions of the electrode pattern have different properties: some regions are covered with transparent conducting material for functionality, while other regions are left uncovered to avoid light reflection. This local differentiation resolves the contradiction between electrode functionality and visual appearance.
2Reliability
If transparent conducting material is used to cover electrode patterns, then conductivity is achieved, but regions covered reflect light while uncovered regions do not, creating visual perception differences
Solution Approach 1:
The electrode pattern is divided into covered and uncovered segments, allowing the system to achieve both conductivity (in covered regions) and visual uniformity (by having uncovered regions that do not reflect light), thereby resolving the contradiction between these two requirements.
Solution Approach 2:
Different regions of the electrode pattern are assigned different properties locally: covered regions provide conductivity while uncovered regions provide visual uniformity. This local quality differentiation allows both requirements to be satisfied simultaneously.

AI summary
A touch substrate and a touch display device are provided. The touch substrate and the touch display device relate to the field of display technology, and aim to solve the problem that in the touch substrate regions covered with electrode patterns reflect light and regions not covered with electrode patterns do not reflect light, thus causing a visual difference and resulting in a degraded display effect. The touch substrate includes a plurality of electrodes, and at least one of the plurality of electrodes has a hollowed-out structure.
