Abstract
The pixel circuit and its drive method, the display panel, and the display device are provided in the present disclosure. The pixel circuit includes a data write unit, a voltage compensation unit, a first switch unit, a second switch unit, a third switch unit, a liquid crystal capacitor, and a storage capacitor. In a dynamic display stage, the first switch unit and the second switch unit are turned on for conduction; and the data write unit transmits a data voltage signal to the liquid crystal capacitor and the storage capacitor. In a static display stage, the third switch unit is turned on for conduction; the voltage compensation unit is controlled to be in conduction through first and second reference voltage signals and a potential signal of the storage capacitor; and a first voltage signal terminal transmits a first voltage signal to the liquid crystal capacitor.
