Abstract
The disclosure discloses a method for driving a pixel circuit, a drive device and a display device. The method includes: receiving grayscale data to be displayed; determining a voltage compensation value, which corresponds to theoretical drive voltage corresponding to the grayscale data to be displayed, according to a pre-acquired correspondence relationship between theoretical drive voltage corresponding to respective grayscale data, and corresponding voltage compensation values; wherein the voltage compensation value is a voltage drop caused by a detection transistor and a drive transistor in the pixel circuit; and compensating the theoretical drive voltage corresponding to the grayscale data to be displayed with the determined voltage compensation value, and then driving a light-emitting diode in the pixel circuit to emit light.
