Abstract
A readout pixel of an input display is provided. The readout pixel includes the fundamental elements as the normal pixel, and further includes a photo sensing element with a second switching element and a third switching element for generating a photo signal. The second switching element includes a second gate electrode connecting to a gate line, a second drain electrode, and a second source electrode connecting to a readout line. The third switching element includes a third gate electrode and a third drain electrode both connecting to a reference voltage, and a third source electrode connecting to the second drain electrode.
