Claim Text:
1. A touch display panel comprising: a first substrate; a second substrate; a display layer interposed between the first substrate and the second substrate; a plurality of scan electrodes interposed between the first substrate and the display layer; a plurality of data electrodes interposed between the scan electrodes and the display layer, and the data electrodes cross the scan electrodes; a plurality of thin-film transistors, each of the thin-film transistors electrically connected to one of the scan electrodes and one of the data electrodes, wherein the thin-film transistors comprise: a plurality of driving electrodes, disposed between the data electrodes and the second substrate, superimposing on the scan electrodes, wherein the driving electrodes overlap the channel and an overlapping portion is at the range from 0 to full area of the channel; a plurality of sensing electrodes disposed between the data electrodes and the second substrate, superimposing on the data electrodes; wherein the scan electrodes, the data electrodes, the driving electrodes and the sensing electrodes are electrically insulated, and the polarity of driving signals of the driving electrodes are negative; a second insulating layer disposed on the first insulating layer; a planar layer disposed between the first insulating layer and the second insulating layer; a first electrode disposed between the planar layer and the second insulating layer; and a second electrode disposed between the second insulating layer and the display layer; wherein the drain electrode electrically is connected to the first electrode or the second electrode selectively.
