Claim:
1. A touch panel, comprising an array substrate and a color filter substrate arranged oppositely, and a liquid crystal layer formed between the color filter substrate and the array substrate, wherein, the array substrate comprises a plurality of gate lines, a plurality of data lines and a plurality of pixel units each formed by adjacent gate lines and adjacent data lines arranged crosswise, each pixel unit comprises a thin film transistor and a pixel electrode, and the color filter substrate comprises a plurality of common electrodes; the pixel electrodes are used for loading data signals through the data lines in a display period of the touch panel, and loading driving signals through the data lines in a touch-control period of the touch panel; the common electrodes are used for loading common electrode signals through common electrode lines in the display period of the touch panel, and outputting sensing signals through the common electrode lines in the touch-control period of the touch panel; and wherein, in the touch-control period of the touch panel, all of the gate lines are enabled simultaneously to turn on all of the thin film transistors, and the pixel electrodes in the same column are electrically connected to one data line corresponding to said column of pixel electrodes through the thin film transistors corresponding thereto, respectively.
