Patent ID: 10768758

Abstract:
A touch display panel including a display panel and a touch electrode layer is provided. The display panel has a display region and a peripheral region. The touch electrode layer includes a non-edge unit region and an edge unit region, wherein the vertical projection of the non-edge unit region is completely located within the vertical projection of the display region, the vertical projection of the edge unit region overlaps the vertical projections of the display region and the peripheral region, and the size of the edge unit region is greater than the size of the non-edge unit region. The touch electrode layer includes a first electrode series and a second electrode series extending in different directions. The area of the first electrode series disposed within the non-edge unit region is A1, the area of the first electrode series disposed within the edge unit region is A1′, and (|A1−A1′|)/A1≤10%. The area of the second electrode series disposed within the non-edge unit region is A2, the area of the second electrode series disposed within the edge unit region is A2′, and (|A2−A2′|)/A2≤10%. A capacitance value between the first and second electrode series disposed within the non-edge unit region is C1, a capacitance value between the first and second electrode series disposed within the edge unit region is C1′, and (|C1−C1′|)≤10%.
