Display Substrate Light-Shielding Layout for Opening Light Leakage

The patent combines the light-shielding function with the touch structure by integrating the light-shielding layer into the touch sensor assembly. The touch electrode pattern itself serves dual purposes: maintaining touch sensitivity while blocking light from reaching the opening. This merging eliminates the need for separate light-shielding elements, thereby improving display reliability without significantly increasing device complexity.

The touch structure is designed to perform multiple functions simultaneously: it provides touch sensing capability while also serving as a light-shielding barrier. The conductive material used in the touch electrode inherently blocks light, so the same structural element fulfills both protective and interactive roles, resolving the contradiction between adding light-shielding functionality and increasing overall device complexity.

Instead of adding separate light-shielding elements on the cover substrate, the patent merges the light-shielding function into the existing touch structure layer. This integration means that the light-shielding layer is formed during the same manufacturing process as the touch electrode, eliminating additional fabrication steps and reducing manufacturing complexity while effectively preventing light leakage.

The touch electrode structure is designed to serve dual purposes: maintaining touch sensitivity while simultaneously providing light-shielding capability. By using the same material layer for both touch sensing and light blocking, the patent avoids the need for separate light-shielding elements, thereby simplifying the manufacturing process and reducing production costs while achieving effective light leakage prevention.
