Abstract:
A pixel circuit compensation method is provided, including: acquiring a threshold voltage of a driving transistor in each subpixel of a display panel; determining whether there is an abnormal voltage in the threshold voltages; and when there is the abnormal voltage, adjusting a compensation signal to be applied to a first subpixel corresponding to the abnormal voltage.
