Abstract
A method for transmitting a touch control driving signal, a touch control chip and an electronic device are provided, which could effectively reduce the influence of the touch control driving signal in a touch control screen on a display screen. The method includes: acquiring a pixel update interval of a pixel circuit in a display screen, the pixel update interval being a time interval during which the pixel circuit receives a data driving signal; and generating a touch control driving signal of a touch control screen according to the pixel update interval, part of the touch control driving signal that is located within the pixel update interval being a constant value.
Claims15
