Touch Panel Substrate with Wide Electrode Ends for Light Transmittance

The patent applies local quality by giving different widths to different parts of the conductor lines. Specifically, the conductor lines have wider portions at their ends and narrower portions in their intermediate sections. This local variation in width compensates for the misalignment between layered conductive films, ensuring that the boundaries between electrode grids do not create visible patterns while maintaining uniform light transmittance across the display surface.

The patent applies parameter changes by varying the width parameter of the conductor lines along their length. The conductor lines transition from wider ends to narrower intermediate sections, creating a gradual change in the physical parameter (width) that compensates for alignment variations between layers while maintaining overall light transmittance and suppressing visible boundaries.

The patent applies segmentation by dividing each conductor line into multiple sections with different widths - wider end portions and narrower intermediate portions. This segmentation allows the conductor line to maintain sufficient electrical conductivity through the wider sections while reducing visibility and improving light transmittance through the narrower sections, effectively balancing electrical performance with optical quality.
