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.
Claims11
A photosensitive pixel circuit of a touch module, comprising:
- an output transistor comprising a first source/drain end, a second source/drain end and a first control end, the first source/drain end receiving a reference signal, the first control end receiving a light detection voltage, and the second source/drain end providing a touch voltage;
- and
- a light detection unit electrically connected to the first control end of the output transistor and receiving a touch scan signal, the light detection unit detecting an intensity of a first light according to the touch scan signal so as to correspondingly provide the light detection voltage.
