Touch Panel Mesh Electrode Layout to Reduce Break Shadows

The patent segments the continuous break pattern into multiple discrete break points arranged in a polyline shape. Instead of a single continuous break line, multiple separate breaks are distributed along a polyline path, which disperses the shadow effect and prevents the formation of a continuous shadow that degrades display quality.

The patent transitions from a simple linear break arrangement to a polyline-shaped break arrangement that incorporates multiple dimensions and directions. The breaks are positioned at vertices and midpoints of sides of cells, creating a multi-directional pattern that scatters light reflection and reduces visible shadows compared to a single-dimensional linear break.

The patent applies different break configurations to different local regions of the electrode pattern. Specifically, breaks are positioned at vertices and midpoints of sides of cells, with varying numbers of breaks in different dummy repeating units (2-10 breaks per unit). This local variation optimizes shadow reduction in each region while managing overall pattern complexity.

Instead of trying to minimize the number of breaks to reduce complexity, the patent inverts the approach by strategically increasing breaks and arranging them in a polyline pattern. This inversion transforms the complexity issue into a solution by showing that structured complexity (polyline arrangement with specific break positions) actually reduces shadow continuity more effectively than simple minimal break patterns.
