Abstract: A pixel circuit and a driving method thereof, display panel and a display device are disclosed. The pixel circuit includes an input control sub-circuit, a switch control sub-circuit, a latch sub-circuit and a light-emitting sub-circuit. The input control sub-circuit writes a data signal into a first node under control of the gate signal terminal. The switch control sub-circuit conducts a first terminal or a second terminal of the latch sub-circuit with the first node under control of a switch signal control terminal. The latch sub-circuit outputs a high-level signal to the first node, when the first node is conductive with the first terminal and outputs a low-level signal to the first node, when the first node is conductive with the second terminal. The light-emitting sub-circuit emits light when the first node is supplied with the high-level signal.
