Abstract
The present application discloses a pixel circuit and its driving method. The pixel circuit includes an input circuit, a control circuit, and 2N output circuits with N being a positive integer. The input circuit is configured to control a voltage level of a respective one of N control nodes under control of a gate-driving signal from each gate line and a first control signal. The control circuit is configured to respectively control a voltage level of each of 2N switching nodes under control of the N control nodes. The 2N output circuits are respectively connected to 2N data-signal terminals and the 2N switching nodes. Among the 2N output circuits, an i-th output circuit is configured to input an i-th data signal from an i-th data-signal terminal of the 2N data-signal terminals to an emission circuit under control of an i-th switching node of the 2N switching nodes.
