Abstract

A pixel circuit includes: a driving sub-circuit including a driving transistor and a storage capacitor; a first reset sub-circuit configured to transmit an initialization signal to a third node under control of at least a first reset signal; a writing sub-circuit configured to transmit the initialization signal to a first node under control of a first scanning signal, and write a data signal received at a data terminal to the first node and perform threshold voltage compensation on the driving transistor under control of the first scanning signal and a second scanning signal; a light-emitting device; and a light-emitting control sub-circuit configured to, under control of a first enable signal and a second enable signal, transmit a voltage signal of a first voltage terminal to a second node, and transmit a current output by the driving transistor to the light-emitting device.
