Abstract

A pixel readout circuit including a reset circuit configured to reset a first node to a first power supply voltage in response to a signal on a first scan line being active; a photodetector configured to generate, responsive to incident light, a charge signal and integrate the charge signal, the integrated charge signal causing a change in a voltage level at the first node; a photosensitive circuit configured to generate a pixel current in response to the change in the voltage level at the first node; and a switch circuit configured to transfer the pixel current to a signal readout line for readout in response to a signal on a second scan line being active.
