Abstract:
1. An in-cell touch display panel, comprising: an active device array substrate, comprising: a substrate, having a display region and a peripheral region adjacent to the display region; a plurality of active devices, arranged in array in the display region; a plurality of pixel electrodes, located in the display region and respectively electrically connected to the corresponding active devices; a plurality of common electrodes, located in the display region and disposed respectively corresponding to the pixel electrodes, wherein the common electrodes are arranged into a plurality of common electrode series and each of the common electrode series extends along a first direction, wherein every two or more common electrode series are connected to each other to form a first touch electrode so that all the common electrodes of the active device array substrate form a plurality of first touch electrodes sequentially arranged along a second direction; a plurality of data signal lines, located in the display region and respectively coupled to the pixel electrodes through the corresponding active devices; and a plurality of switches, wherein every two or more of the data signal lines are electrically directly connected to one of the plurality of switches, wherein the pixel electrodes and their respective data signal lines are coupled to a same switch of the plurality of switches and together form a second touch electrode, wherein all the pixel electrodes and their respective data signal lines form a plurality of second touch electrodes arranged along the first direction; an opposite substrate, opposite to the active device array substrate; and a display medium layer, disposed between the active device array substrate and the opposite substrate.
