Abstract
An organic light-emitting diode pixel circuit addresses problems associated with power consumption of a conventional 3D image display using two displayed adjacent frames of image signals that are spaced by a black picture. The pixel circuit includes a signal pre-storage module for storing a signal in a current frame of image signal, when the voltage of a first drive signal is higher than the voltage of a second drive signal and a gate line connected with the pixel is enabled; and a drive module for driving a drive transistor when the voltage of the first drive signal is higher than the voltage of the second drive signal; and to generate a current drive signal from the signal stored in the signal pre-storage module in the current frame of image signal, when the voltage of the first drive signal is not higher than the voltage of the second drive signal.
