Touch Wiring Overlap Layout for Narrow-Bezel Display Panels

The patent transitions from a single-layer wide wiring structure to a multi-layer overlapping wiring structure. The first and second touch wirings are arranged in different layers with partial overlap, effectively utilizing the third dimension (vertical stacking) to reduce the horizontal width of the binding region while maintaining adequate current carrying capacity and reporting rate.

The patent implements a nested wiring configuration where the first touch wiring and second touch wiring overlap in a nested manner. The second wiring is positioned such that it partially overlaps with the first wiring, creating a compact nested structure that reduces the overall width requirement while maintaining electrical performance.

The patent segments the touch wiring into multiple independent layers (first touch wiring and second touch wiring) with distinct spatial positions. Each layer is separately configured and connected through via holes, allowing independent optimization of each wiring path while maintaining adequate spacing between layers to prevent short circuits.

The patent utilizes vertical layering to separate the first and second touch wirings into different z-dimensions. This vertical separation provides natural insulation and spacing between the wirings, reducing the risk of short circuits while still achieving low resistance through the multi-layer configuration.

The patent employs a nested wiring arrangement where the first and second touch wirings overlap in a compact nested configuration. This nesting minimizes the horizontal footprint of the wiring structure, enabling the display panel to achieve a narrow frame design while maintaining the double-layer wiring structure necessary for high reporting rate.

The patent resolves the frame width issue by moving the wiring expansion into the vertical dimension through multi-layer stacking. Instead of expanding horizontally which would increase frame width, the wiring structure expands vertically through layered overlapping, thereby maintaining a narrow frame while achieving adequate wiring capacity for high reporting rate.
