Claim 10:
11. A driving method, comprising:
acquiring a display sensitive interval of a display layer of a screen, wherein the display sensitive interval comprises a pixel update interval of the display layer, and the pixel update interval is a time interval for a pixel in the display layer to receive a data signal;
outputting a driving signal to a display layer of the screen, wherein there is an overlap between a period when a driving circuit outputs the driving signal and the display sensitive interval, and during the period of outputting the driving signal, adjusting a value of a driving impedance of a driving circuit in a touch control chip to be greater that than a value of the driving impedance in a time interval outside the display sensitive interval, so that a slope of a flipping edge of the driving signal in the display sensitive interval is smaller than a slope of the flipping edge of the driving signal in the time interval outside the display sensitive interval, wherein a peak amplitude of the driving signal in the display sensitive interval and in the time interval outside the display sensitive interval are equal.
