Pixel compensation circuit, compensation method and display device

The invention relates to a pixel compensation circuit, a compensation method and a display device. The pixel compensation circuit comprises a drive transistor and an OLED light-emitting element. A first switch element responds to a reset signal and transmits an initialization signal to the control end of the drive transistor; a second switch element responds to a scanning signal and transmits a data signal to the first end of the drive transistor; a third switch element responds to the scanning signal and transmits the data signal to the first end of a coupling capacitor; the second end of the coupling capacitor is connected with a first power supply signal end; a fourth switch element responds to the scanning signal and is connected with the control end and the second end of the drive transistor; a fifth switch element responds to a control signal and transmits the first power supply signal to the first end of the drive transistor; a sixth switch element responds to the control signal and transmits the current outputted from the drive transistor to the OLED light-emitting element. A storage capacitor is connected between the first power supply signal end and the control end of the drive transistor. The present disclosure improves the uniformity of the OLED luminance brightness.
