Claim:
1. An organic light-emitting diode pixel circuit comprising a signal pre-storage module, a drive module, an organic light-emitting diode, and a drive transistor; the signal pre-storage module comprising: the drive module comprising: wherein: the source of the drive transistor receives a first drive signal, and a drain of the drive transistor is connected with an anode of the organic light-emitting diode, and a cathode of the organic light-emitting diode receives a second drive signal; the signal pre-storage module is configured to store the data signal received by the first end of the signal pre-storage module, when a voltage of the first drive signal is higher than a voltage of the second drive signal and a gate line connected with the pixel is enabled; and the drive module is configured to drive the drive transistor by the first end of the drive module using a previous drive signal to enable the organic light-emitting diode to emit light when the voltage of the first drive signal is higher than the voltage of the second drive signal, the previous drive signal being generated by the drive module from a signal, in a previous frame of image signal; and to generate a current drive signal from the data signal stored in the signal pre-storage module, when the voltage of the first drive signal is not higher than the voltage of the second drive signal.
