1. A touch display screen, comprising a cover plate, a color filter, a liquid crystal layer, a display electrode, a substrate and a backlight unit which are stacked sequentially from top to bottom, wherein:

  • the touch display screen further comprises a touch detecting unit and a display control unit;

    the display electrode comprises an electrode in a first direction and an electrode in a second direction which intersects with the first direction;

    the electrode in the first direction and the electrode in the second direction are connected to the touch detecting unit,the touch detecting unit is adapted to detect mutual capacitance formed between the electrode in the first direction and the electrode in the second direction, and determine a touch on the touch display screen based on the detected mutual capacitance;

    the display electrode is further connected to the display control unit, the display control unit is adapted to control the display electrode to perform liquid crystal display; and

    the display control unit and the touch detecting unit operate in a time-sharing manner.
