摘要
A touch control chip, a touch detection method, a touch detection system and an electronic device, and the touch chip includes: a synchronization module, a touch drive module, and a touch detection module. The synchronization module is electrically connected to a display drive chip, to enable touch driving performed by the touch drive module to have an association relationship with a display control signal of the display drive chip; the synchronization module is electrically connected to the touch drive module, to enable the touch drive module to drive a touch sensor under control of the display control signal; and the touch detection module is electrically connected to the touch sensor, to detect an output signal of the touch sensor to determine a touch position. The touch detection system cancels or reduces interference from a display system, thereby improving the signal-to-noise ratio of the touch detection system.
