Abstract
An OLED pixel compensation circuit, a driving method thereof, and a display device are provided. The OLED pixel compensation circuit includes an input sub-circuit, a compensation sub-circuit, a driving sub-circuit and a light-emitting sub-circuit. The input sub-circuit is coupled to the compensation sub-circuit and configured to input a data signal into the compensation sub-circuit. The compensation sub-circuit is coupled to the driving sub-circuit and the light-emitting sub-circuit and configured to compensate a threshold voltage of the driving sub-circuit. The driving sub-circuit is configured to drive the light-emitting sub-circuit to emit light after the threshold voltage of the driving sub-circuit is compensated.
