Narrow Frame Display Panel With Varying Touch Signal Line Widths

The patent applies local quality by varying the line width of touch signal lines across different regions. Specifically, the line width is wider in the middle region and narrower at the edges, creating non-uniform local properties that optimize both reliability and space utilization. This local differentiation allows the structure to better withstand bending stresses and edge cracks while maintaining compact dimensions.

The patent implements parameter changes by continuously varying the line width parameter of touch signal lines from the edge toward the center. The line width transitions from a first width at the edge to a second width in the middle, with intermediate widths in between. This gradual parameter change optimizes the distribution of mechanical stress and electrical performance, enhancing reliability while controlling the non-display area width.

The patent uses local quality to create wider line widths in the middle region of the non-display area where touch signal lines are less susceptible to edge cracks. This local thickening provides mechanical reinforcement exactly where needed, allowing the overall non-display area width to be reduced while maintaining reliability.

The patent applies parameter changes by gradually varying the line width from edge to center, creating a smooth transition that avoids stress concentration. The line width parameter is optimized at each position to balance mechanical strength against space constraints, enabling narrow frame design without compromising touch signal line reliability.
