Abstract
A pixel circuit, a driving method, and array substrate, the pixel circuit includes a plurality of sub-pixel units each of which includes an input sub-circuit, a driving sub-circuit, a light emitting control sub-circuit, and a level maintaining sub-circuit; the input sub-circuit is connected to a data line; the driving sub-circuit outputs a driving current to the light emitting control sub-circuit via a second node under control of a first node; the light emitting control sub-circuit drives a light emitting element to emit light according to a received driving current under control of a light emitting control line; and the level maintaining sub-circuit is connected between the first node and a first voltage terminal to maintain a level at the first node.
