Transparent Electrode Base for Thin Touch Panel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a touch panel that can reduce thickness and bezel size, particularly one with a multi-touch function and curved glass capability, while maintaining sensitivity and usability.
Innovation Solution
A touch panel design featuring a substrate with transparent electrodes formed on a transparent electrode base, such as a PET film, which allows for flexible and thin construction, improved touch sensitivity, and enhanced visibility through index matching of hard coating and insulating layers, along with an anti-reflective layer to reduce glare.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If transparent electrodes are formed directly on the substrate to reduce thickness, then the thickness is reduced, but the electrical characteristic control becomes difficult
Solution Approach 1:
The patent introduces a transparent electrode base (such as a PET film) as an intermediary layer between the substrate and the transparent electrodes. This base layer serves as a mediator that allows the transparent electrodes to be formed with controlled electrical characteristics while maintaining the overall thinness of the touch panel structure.
2Measurement precision
If multiple layers are added to improve touch sensitivity and multi-touch function, then touch sensitivity is improved, but the thickness increases
Solution Approach 1:
The patent combines multiple transparent electrodes (first transparent electrode and second transparent electrode extending in different directions) on the same transparent electrode base, merging their functions into a single integrated structure that enables multi-touch capability without requiring separate stacked layers that would increase thickness.
Solution Approach 2:
The patent uses a flexible transparent electrode base (such as PET film) that allows the formation of thin-film transparent electrodes with precise electrical characteristics. This flexible base enables the creation of sensitive touch detection layers while maintaining overall thinness through advanced thin-film fabrication techniques.
3Ease of operation
If curved glass is used to improve aesthetics and grip, then usability is improved, but manufacturing complexity increases
Solution Approach 1:
The patent applies parameter changes by forming transparent electrodes on a flexible transparent electrode base that can be conformally deposited on curved surfaces. This allows the touch panel to be manufactured with curved glass by adjusting the deposition parameters and using flexible substrates that can be shaped into curved forms without breaking the electrode pattern.
