Touch Display Panel Mesh Line Widths for Uniform Reflectivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Touch display panels with metal mesh structures exhibit optical defects such as bright and dark zones due to varying line widths causing uneven light reflection, especially in regions with and without dispersion compensation, affecting display quality and user experience.
Innovation Solution
The touch display panel is designed with varying line widths and break or opening rates in different regions to equalize light reflectivity across the panel, ensuring consistent reflection regardless of line width variations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If uniform line width is used across the touch panel, then manufacturing precision is improved, but optical uniformity deteriorates due to bright and dark zones caused by varying light reflection in different regions
Solution Approach 1:
The patent applies local quality by varying the line width of touch lines according to different regions of the display panel. Specifically, touch lines in the first region (with dispersion compensation) have a first line width, while touch lines in the second region (without dispersion compensation) have a second line width that is different from the first. This regional differentiation compensates for the optical effects caused by dispersion compensation, thereby achieving uniform light reflection and eliminating bright and dark zones across the entire panel.
2Illumination intensity
If line width is varied to compensate for dispersion compensation effects, then optical uniformity is improved, but device complexity increases due to multiple line width specifications
Solution Approach 1:
The patent implements local quality by defining different line width specifications for different regions of the touch panel. The first region, which includes dispersion compensation structures, uses a first line width for its touch lines, while the second region, without dispersion compensation, uses a second line width. This regional differentiation allows the patent to achieve uniform optical properties across the entire panel while managing the complexity through a systematic regional classification approach.

Function Achieved in This Case
This design minimizes optical defects, enhancing display quality by maintaining uniform reflectivity and improving user experience.
Implementation Method 1
reflectivity is a ratio of light, which is in an incident light from a side of the touch structure layer and irradiated onto the anode layer through the plurality of touch lines, and is further reflected back to the touch structure layer by the anode layer

AI summary
A touch panel display includes a display panel and a touch panel disposed on a side of the display panel. The touch panel includes a touch structure layer. The display panel includes an anode layer. The touch structure layer includes a plurality of touch lines, and the plurality of touch lines define a plurality of touch meshes. The touch display panel includes a first region and a second region, and the plurality of touch lines include a plurality of first touch lines located in the first region and a plurality of second touch lines located in the second region. A line width of at least one first touch line in the plurality of first touch lines is smaller than a line width of at least one second touch line in the plurality of second touch lines. Reflectivity of the first region is equal to reflectivity of the second region.
