Abstract
A pixel circuit includes sub-pixel circuits each including a reset sub-circuit, a driving sub-circuit, and a light-emitting device. The reset sub-circuit is configured to input a voltage provided by an initial voltage terminal to the driving sub-circuit under control of a signal from a first reset control terminal. The driving sub-circuit is configured to control a driving current flowing through the light-emitting device according to a data signal output by a data terminal. The sub-pixel circuits include first and second sub-pixel circuits that are located in two adjacent columns, and connected to a same data terminal. A first reset control terminal and a writing control terminal of the first sub-pixel circuit are connected to first and second scanning signal terminals. A first reset control terminal and a writing control terminal of the second sub-pixel circuit are connected to second and third scanning signal terminals.
