Abstract
A circuit for driving a pixel includes a driving transistor having a first end connected to a first node, a control end connected to a second node, and a second end connected to a third node; a writing circuit connected to a first scanning signal and the first node and configured to transmit a data signal to the first node; a reset circuit connected to a second scanning signal and configured to transmit a reference signal to the second node; a compensation circuit connected to a compensation control signal and configured to put through a connection between the second end and the control end of the driving transistor in response to the compensation control signal, wherein the compensation control signal is different from the first scanning signal and the second scanning signal; and an energy storage circuit connected between a first power end and the second node.
