Patent ID: 10768765

Abstract:
A touch display device includes a display component and a sensing layer disposed above the display component. The display component has a display area having a corner with an arced edge. The arced edge has a radius of curvature. The sensing layer disposed above the display component includes: a plurality of first sensing portions arranged along a first direction and electrically connected to each other, wherein the first sensing portions have an arrangement pitch P in the first direction; and a plurality of second sensing portions disposed adjacent to the first sensing portions, arranged along a second direction and electrically connected to each other, wherein the second direction is different from the first direction. The arrangement pitch P satisfies the following equation: P>[2 cos(45−θ/2)−√{square root over (2)}]r, wherein, r represents the radius of curvature, and θ represents an angle corresponding to the arced edge of the corner and satisfies 0°<θ≤90°.
