Abstract
Provided is a pixel circuit. The pixel circuit includes a conversion element forming a voltage of an input level at a first node, a first transistor adjusting the voltage of the first node to a first level in response to a first signal received at a first time interval, a first capacitive element forming a voltage at a second node based on the voltage of the first node, a second transistor adjusting a level of the voltage of the second node to a second level in response to the first signal, a third transistor forming a voltage at a third node, a fourth transistor outputting a current in response to a second signal received in a second time interval, and a. fifth transistor adjusting the voltage of the third node to a third level in response to a third signal received in a third time interval.
