Abstract: A pixel circuit (300) includes a pixel driver (302) configured to receive a data signal (DATA[M]) and drive a light emitting element (D) based on the data signal (DATA[M]), a first power signal (V1) coupled to an anode of the light emitting element (D) through the pixel driver (302), and a second power signal (V2) coupled to a cathode of the light emitting element (D). The second power signal (V2) is configured to vary based on the data signal (DATA[M]). In a first period (T1) of the data signal (DATA[M]), a value of the second power signal (V2) is configured to be lower than a value of the first power signal (V1), and in a second period (T2) of the data signal (DATA[M]), the value of the second power signal (V2) is configured to be higher than the value of the first power signal (V1).
