Abstract
A photosensitive pixel circuit of a touch module including an output transistor and a light detection unit is provided. The output transistor receives a reference signal and provides a touch voltage controlled by a light detection voltage. The light detection unit is electrically connected to the output transistor, and receives a touch scan signal. The light detection unit detects an intensity of a light according to the touch scan signal so as to correspondingly provide the light detection voltage.
