Abstract
A touch display panel is provided, including a common electrode ring, a first and a second common electrode pattern, pixel structures, an edge common signal line, and common signal lines disposed on a substrate. The first and second common electrode patterns and the pixel structures are located in a region surrounded by the common electrode ring. The first common electrode pattern is spaced from the second common electrode pattern by a gap. The first and the second common electrode patterns respectively overlap some of the pixel structures. The edge common signal line is disposed on the substrate, traces along the gap, and extends toward the common electrode ring to be electrically connected to the common electrode ring. The first common electrode pattern overlaps and is electrically connected to one common signal line. The second common electrode pattern overlaps and is electrically connected to another common signal line.
