Touch Panel Light Processing Structure for Outdoor Brightness

The patent applies local quality by creating protrusions only on specific regions of the touch electrode surface where light reflection occurs, rather than modifying the entire structure. The protrusions are strategically positioned to scatter external light while preserving the touch electrode's electrical functionality, thus locally improving optical performance without compromising overall touch sensitivity.

The patent employs curvature by designing protrusions with rounded or curved surfaces on the touch electrode. These curved structures effectively scatter incident light from various angles, reducing specular reflection and improving outdoor visibility. The spherical or curved geometry of the protrusions enables omnidirectional light scattering while maintaining electrical conductivity.

The patent merges the light processing function directly into the touch electrode structure by forming protrusions on the metal mesh itself, rather than adding a separate light processing layer. This integration approach reduces device complexity by combining multiple functions (touch sensing and light management) into a single component, eliminating the need for additional structural layers.

The touch electrode structure serves dual purposes: it maintains its primary function of touch sensing while simultaneously performing light scattering through its protrusions. The same metal mesh structure that detects touch input also processes light, making the system self-sufficient and reducing the need for separate dedicated components for each function.
