Touch Panel Polygonal Mesh Structure for Uniform Resistance

The patent transforms the symmetric rhombus-shaped grid into an asymmetric irregular polygonal grid where the length in one direction is deliberately made greater than the width in the perpendicular direction. This asymmetric design compensates for the directional resistance differences inherent in rhombus grids, achieving uniform resistance across different electrode orientations while maintaining manufacturing simplicity through standardized polygonal cell structures.

The patent applies local quality by making each polygonal grid cell have different dimensional characteristics along different directions. Specifically, the grid cells are designed with longer dimensions along the electrode extension direction and shorter dimensions perpendicular to it, creating local geometric variations that compensate for resistance differences and ensure uniform touch sensitivity across the entire electrode surface.

The asymmetric irregular polygonal grid design with controlled length-width ratios eliminates the need for complex computational corrections. By embedding the resistance compensation directly into the geometric design of the grid cells, the system achieves uniform resistance characteristics that simplify the touch calculation algorithms, reducing computational burden while maintaining cost-effective manufacturing.
