Abstract
A method for driving a pixel circuit. The pixel circuit includes a drive transistor. The method includes: acquiring a theoretical threshold voltage of the drive transistor and actual threshold voltages of the drive transistor at a plurality of different gray levels; determining compensation data voltages of the drive transistor at the plurality of different gray levels according to the theoretical threshold voltage of the drive transistor and the actual threshold voltages of the drive transistor at the plurality of different gray levels; and driving the pixel circuit emit light according to the compensation data voltages of the drive transistor at the plurality of different gray levels.
