Abstract
A pixel circuit driving method for driving a pixel circuit having light sensing function is provided. The pixel circuit includes a light emitting element and a switching circuit electrically connected to the light emitting element. The pixel circuit driving method includes performing light emitting and light sensing steps. The light emitting step includes providing a lighting emitting control signal for the pixel circuit to control the light emitting element to emit light during a light emitting period. The light sensing step includes turning on the switching circuit and providing a reference potential to the light emitting element, in which the reference potential is lower than a cathode potential of the light emitting element. A reverse current proportional to light intensity based on a difference between the reference potential and the cathode potential is generated; and brightness of the light emitting element based on the reverse current is adjusted.
