Abstract
The present invention discloses a driver circuit and a driving method thereof including a first thin film transistor, a second thin film transistor, and a third thin film transistor. Increasing a photocurrent of the second thin film transistor, i.e., amplifying the photocurrent of the thin film transistor to a photosensitive thin film transistor, advantages enhancement of a signal intensity and a signal-noise ratio of the photocurrent read out by the read line to solve the issue of weak a photocurrent signal from the photosensitive display.
