Mesh Electrode Index Matching Layers Light Transmittance

The electrode layer is segmented into a mesh pattern with progressively smaller line widths from the center toward edges, allowing light to pass through more gaps in the mesh while maintaining touch detection capability. This segmentation resolves the contradiction by dividing the continuous electrode into discrete conductive elements that minimize visual obstruction.

Different regions of the mesh electrode layer have different line widths adapted to local requirements: wider lines at the center for better touch detection, and progressively narrower lines toward edges for improved light transmittance. This local variation in geometry optimizes both touch sensitivity and optical performance simultaneously.

The mesh electrode implements local quality by varying line widths across different regions, with narrower lines at edges where trace phenomenon is more noticeable. This localized optimization reduces the visual impact of electrode traces while preserving touch detection functionality in all areas.

The line width parameter of the mesh electrode is changed progressively from center to edge, creating a gradient structure that minimizes trace visibility. By adjusting this geometric parameter spatially, the invention eliminates the harmful trace phenomenon while maintaining electrical functionality.

The mesh electrode structure segments the electrode layer into a regular pattern of conductive lines and transparent gaps, achieving high light transmittance through the gaps. This segmented approach simplifies the optical path while maintaining electrical connectivity through the conductive network.

The mesh electrode introduces a two-dimensional patterned structure that simultaneously provides electrical conductivity in one dimension and optical transparency in the perpendicular dimension. This dimensional approach resolves the contradiction by exploiting spatial arrangement rather than material properties alone.
