1. A display method for an in-cell touch display screen comprising:
in a pre-display phase,
outputting a predetermined picture;
performing initialization scanning on touch sensor electrodes of a TFT array substrate to obtain initialization scanning data as basic data; and
in a display phase,
outputting display picture frames and outputting the predetermined picture between every two consecutive display picture frames, and every time the predetermined picture is output, scanning the touch sensor electrodes to obtain display scanning data; and
comparing the display scanning data and the basic data to determine whether a touch occurs.
