Abstract
A pixel unit circuit includes a light emitting element, a first end being connected to a low level input end; a storage capacitor sub-circuit, a first end being connected to a DC voltage input end; a driving transistor, a gate electrode being connected to a second end of the storage capacitor sub-circuit, and a first electrode being connected to a second end of the light emitting element; a light emitting control sub-circuit, a control end being connected to a light emitting control line, the first end being connected to a high-level input end, and the second end being connected to a second electrode of the driving transistor, and configured to control whether the second electrode of the driving transistor is connected to the high level input end; and a charge compensation control sub-circuit, connected to a gate line, a data line and the gate electrode of the driving transistor.
