Abstract
A touch display panel includes pixels, a first sensing line segment, a first connecting electrode and an insulating layer. The pixels are divided into a first group and a second group, and the first group includes a first region and a second region. Each pixel includes an active device, a pixel electrode and a common electrode. The first sensing line segment is disposed in a portion of the pixels of the first region. The insulating layer includes at least one first opening be adapted to expose a portion of the first sensing line segment or a portion of the first connecting electrode, and the first connecting electrode is connected to the portion of the first sensing line segment via the first opening to form a first sensing line. The common electrode at the first region is connected to the first connecting electrode, the common electrode at the second region is connected to the common electrode at the first region to form a first sensing electrode, and the common electrode at the second region is not directly connected to the first connecting electrode.
