Abstract
A display device, a pixel compensation circuit and a driving method thereof are disclosed. The pixel compensation circuit includes: a driving transistor, an initialization circuit, a storage circuit, a first data writing circuit, a second data writing circuit, a compensation circuit and a light emitting control circuit. A first terminal of the storage circuit is coupled to the gate electrode of the drive transistor, and the first data writing circuit is configured to write a data signal to a second terminal of the storage circuit. The second data writing circuit is configured to change a potential of the second terminal of the storage circuit so that a potential of the first terminal of the storage circuit is associated with the data signal. The compensation circuit is configured to charge the first terminal of the storage circuit so that it is associated with a threshold voltage of the drive transistor.
