Abstract:
1. A touch display panel, comprising: a flat display panel having a display area and a peripheral area located around the display area; and a touch sensing device disposed on the flat display panel, wherein the touch sensing device comprises: a plurality of center sensing series being corresponding to the display area of the flat display panel, each of the center sensing series being consisted of a plurality of center sensing electrodes serially connected, wherein the center sensing series comprises a plurality of first sensing series disposed along a first direction and a plurality of second sensing series disposed along a second direction; and at least a margin sensing series disposed along a margin of the display area, the at least a margin sensing series being consisted of a plurality of margin sensing electrodes serially connected, and each of the margin sensing electrodes comprising an inner portion and a rectangular outer portion, wherein an area of the inner portion is substantially half of an area of the center sensing electrode, and a parallel hemline is formed by serially connecting the rectangular outer portions, wherein the parallel hemline of the rectangular outer portions is substantially parallel to one of the first direction and the second direction, a shape of each of the center sensing electrodes is a diamond shape, a side length of each of the center sensing electrodes is a, a width of the rectangular outer portion is from a/2 to a/2√{square root over (2)} in each of the margin sensing electrodes, and the width is substantially perpendicular to a base of the inner portion.
