A touch module outputting sensed data array, the touch module including a sensor array, and a sensed data array generator, the sensed data array generator including: a multiplexer, used to select one line from a plurality of scan output lines of the sensor array for delivering an analog sensed output signal, wherein the analog sensed output signal carries sensed array information of the sensor array; an analog to digital converter, used for converting the analog sensed output signal to a first digital signal, to provide a first sensed data array corresponding to the sensed array information; a memory, used for storing the first sensed data array; and an output control unit, used for transforming the first sensed data array to a second sensed data array.
