Abstract
The present application discloses a pixel-driving circuit in a display panel. The pixel-driving circuit includes a first transistor being provided with a fixed voltage, a driving transistor having a gate configured to receive the fixed voltage controlled by the first transistor and a drain coupled to a first power supply, a capacitor coupled between the gate and a source of the driving transistor, a light-emitting device coupled to the source and a second power supply, a second transistor having a drain coupled to the source of the driving transistor and a source coupled to a data line, a sensing sub-circuit coupled to the data line in a first period, and a driving sub-circuit coupled to the data line in a second period. The sensing sub-circuit and the driving sub-circuit are configured to connect to the data line in a time-divisional manner respectively for sensing and compensating the pixel-driving circuit.
