Abstract
A pixel drive circuit, including a data input circuit, a switch circuit, an energy storage circuit and a light-emitting control circuit. The light-emitting control circuit has a control end connected to the data input circuit, an input connected to a first power supply, and an output connected to an anode of a light-emitting device. A cathode of the light-emitting device is connected to a second power supply. The first power supply outputs a low-potential voltage in a reset phase, and outputs a first high-potential voltage in a compensation phase, a writing phase and a light-emitting phase. The second power supply outputs a second high-potential voltage in the reset, compensation and writing phases, and output a low-potential voltage in the light-emitting phase. The switch circuit is switched on in the reset, compensation and light-emitting phases, and is switched off in the writing phase.
