Touch Unit Interconnecting Member Opening for Light Transmittance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch panels with under-screen photographed function often block ambient light, degrading image quality and user experience due to structural limitations that compromise light transmittance and touch functionality.
Innovation Solution
A touch unit design featuring intersecting first and second touch electrodes connected by interconnecting members, with at least one member defining a first opening to allow light transmission without compromising electrical performance, ensuring high light transmittance and maintaining touch functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If touch electrodes and interconnecting members are used to maintain touch functionality, then touch sensing capability is preserved, but light transmittance is blocked and image quality is degraded
Solution Approach 1:
The interconnecting member is segmented by introducing openings (through-holes or recesses) that divide the continuous conductive path into sections. This segmentation allows light to pass through the openings while the remaining conductive portions maintain electrical connectivity between touch electrodes, thus resolving the contradiction between touch functionality and light transmittance.
Solution Approach 2:
The interconnecting member is designed with non-uniform structure: certain regions (openings) are made transparent to light while other regions (conductive paths) maintain electrical functionality. This local differentiation of properties allows simultaneous achievement of light transmission and electrical conduction in different spatial zones of the same component.
2Illumination intensity
If openings are introduced in interconnecting members to improve light transmittance, then image quality is enhanced, but electrical connectivity may be compromised
Solution Approach 1:
The opening in the interconnecting member acts as an intermediary element that mediates between light transmission and electrical connectivity requirements. By carefully designing the opening's position, size, and shape, light can pass through while the surrounding conductive material maintains sufficient electrical path for signal transmission, thus the opening serves as a mediator that enables both functions.
Solution Approach 2:
The electrical and optical parameters of the interconnecting member are optimized by adjusting the opening's geometric parameters (size, shape, position). By changing these parameters, the balance between light transmittance and electrical conductivity is tuned to achieve both high image quality and reliable touch functionality simultaneously.
