Touch Panel Anti-Moire Functional Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current touch panels experience interference between the metal mesh layer and the black matrix in the display module, resulting in moire fringes that degrade the display effect.
Innovation Solution
A touch panel with a metal mesh layer and at least one functional layer featuring an anti-moire pattern, which can be a transparent conductive layer or an insulation layer, is formed to suppress interference between the metal mesh layer and the black matrix, thereby improving the display effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a metal mesh layer is used in the touch panel, then the touch control function is achieved, but interference with the black matrix occurs causing moire fringes
Solution Approach 1:
The patent introduces a black matrix anti-moire layer as an intermediary component between the metal mesh layer and the black matrix. This intermediate layer has a specific pattern design that mediates the interaction between the metal mesh and black matrix, preventing direct interference and eliminating moire fringes while preserving the touch control function of the metal mesh layer.
2Object-affected harmful factors
If additional anti-moire layers are added to suppress moire fringes, then display quality is improved, but the number of film layers increases complicating manufacturing
Solution Approach 1:
The patent merges the anti-moire function with the black matrix structure by integrating the black matrix anti-moire layer into the existing black matrix formation process. This combination approach allows the anti-moire functionality to be achieved without adding separate independent layers, thereby improving display quality while avoiding excessive complexity in the film layer structure.
Solution Approach 2:
The black matrix anti-moire layer serves multiple functions simultaneously: it acts as part of the black matrix structure for display purposes and also provides the anti-moire pattern function to suppress interference. This multi-functionality reduces the need for additional dedicated anti-moire layers, simplifying the overall structure.

AI summary
A touch panel, manufacturing method thereof, and a touch device, the touch panel including a substrate; a metal mesh layer located on the substrate; and at least one layer of a functional layer having an anti-moire pattern. The functional layer reduces the occurrence of moire fringes in a display picture and improves display effect of a touch device.
