  • Touch control chip, coding method and electronic device
    Patent number: 11928287
    Abstract: A touch control chip, a coding method, and an electronic device are provided, which can effectively reduce influence of a coding signal of a touch control layer of a screen on a display layer. The touch control chip includes: a driving circuit configured to output the coding signal to a display layer of the screen; and a control circuit configured to adjust a driving impedance of the driving circuit during a period when the driving circuit outputs the coding signal, so that a value of the driving impedance in a display sensitive interval of the display layer is greater than a value of the driving impedance in a time interval outside the display sensitive interval, where the display sensitive interval includes a pixel update interval of the display layer, and the pixel update interval is the time interval for a pixel in the display layer to receive a data signal.
