Abstract
The present disclosure discloses a driving display method for an in-cell touch display screen. The method comprises the following steps: outputting a predetermined picture; performing initialization scanning on touch sensor electrodes of a TFT array substrate to obtain initialization scanning data as basic data; alternately outputting a display picture and the predetermined picture, and after the predetermined picture is output, scanning the touch sensor electrodes to obtain display scanning data; comparing the display scanning data and the basic data to determine whether a touch occurs. The disclosure also discloses an in-cell touch display screen and a display apparatus with the in-cell touch display screen. By inserting a predetermined picture before normally display and between any two successive frames of the display picture and performing touch scanning each time a predetermined picture is displayed, the present disclosure can prevent the parasitic and coupling capacitors from affecting the scanning result of the touch control IC, and thus reduce the possibility of erroneous judgment of touches.
