Abstract
A pixel compensation circuit includes a data signal writing module, a high voltage writing module, a first reference voltage generation module, a driving transistor, a capacitor and a light emitting device. The data signal writing module is connected to a first end of the capacitor. The high voltage writing module is connected to the first end of the capacitor. The first reference voltage generation module is connected to a second end of the capacitor, an anode of the light emitting device and a drain electrode of the driving transistor. A gate electrode of the driving transistor is connected to the second end of the capacitor, a source electrode thereof is connected to the high voltage writing module, and the drain electrode thereof is connected to the anode of the light emitting device. A cathode of the light emitting device is connected to a common grounding electrode.
