The present disclosure is directed to a photosensitive touch circuit and a control method thereof. The circuit includes a first switch unit, a driving switch unit, a photosensitive switch unit, a first storage capacitor, and a second storage capacitor, wherein: the first switch unit is connected to a data signal line and transmits a data signal to the driving switch unit in response to a first control signal; the driving switch unit is connected to a liquid crystal capacitor and the first storage capacitor, and writes a received data signal thereto in response to a second control signal; and the photosensitive switch unit is connected to the second storage capacitor, generates a touch signal, and outputs a signal in the second storage capacitor to the data signal line through the first switch unit in response to a third control signal.
