Segmented Metal Mesh Touch Electrodes for Display Brightness Uniformity

The touch electrode is divided into a main electrode and multiple branch electrodes that are spatially separated. The branch electrodes extend from the main electrode in different directions, creating a segmented metal mesh structure. This segmentation reduces the continuity of metal reflections, thereby minimizing the visual brightness difference between touch electrodes and adjacent areas while maintaining touch functionality.

The branch electrodes are positioned at specific locations extending from the main electrode, creating localized metal structures rather than continuous coverage. This local quality approach ensures that metal is present where needed for touch sensing while being absent or minimized in areas that would cause visual brightness discrepancies, thus optimizing both touch function and visual uniformity.

The metal mesh lines are segmented into discrete sections with controlled gaps and etched fractures. These segments are strategically placed to maintain electrical connectivity for touch functionality while breaking up continuous metal reflections. The segmentation creates a pattern that reduces light reflection variability by preventing large continuous reflective surfaces.

Gaps and etched fractures are introduced at specific locations within the metal mesh structure rather than uniformly throughout. This local quality approach allows the metal mesh to maintain connectivity where needed for touch sensing while creating controlled disruptions in areas that would otherwise create excessive light reflection. The localized modification optimizes the balance between functionality and visual uniformity.
