Abstract
An electronic device and a method for driving a touch sensor integrated in a display module of an electronic device are provided. The electronic device includes a display module with a touch sensor integrated in the display module, a drive circuitry, and a sense circuitry. The drive circuitry is configured to apply drive signals to the display module and the touch sensor. The sense circuitry is configured to determine a mode for the drive circuitry to apply the drive signals, detect one or more sense signal from the touch sensor, analyze the sense signals, and change the mode of the drive signals for the touch sensor.
