Abstract: The present disclosure relates to the field of display technologies, and more particularly, to a pixel circuit. The pixel circuit includes a drive transistor and an OLED light-emitting element. A first switching element transmits an initialization signal to the drive transistor in response to a reset signal. A second switching element transmits a data signal to the drive transistor in response to a scanning signal. A third switching element transmits the data signal to a coupling capacitor in response to the scanning signal. A fourth switching element is connected to the drive transistor in response to the scanning signal. A fifth switching element transmits a first power signal to the first terminal of the drive transistor in response to a control signal. A sixth switching element transmits, in response to the control signal, an output current of the drive transistor to the OLED light-emitting element.

Abstract: The present disclosure discloses a display panel, a pixel compensation circuit and a method for controlling the same. The pixel compensation circuit includes a driving transistor; a resetting circuit configured to reset the driving transistor under the control of a driving signal; a compensation circuit configured to compensate for the driving transistor; and a light-emitting control circuit configured to drive the light-emitting element to emit light under the control of a light-emitting control signal.
