Abstract
A pixel circuit and a display device are provided. The pixel circuit is utilized for driving a light emitting diode. The pixel circuit includes a storage capacitor, a selector, a memory device, and a write switch. The storage capacitor is coupled to the light emitting diode. The selector selects a first signal or a second signal to the storage capacitor according to a stored data. The memory device is coupled to the selector. The memory device stores a written data to obtain the stored data. The write switch is coupled to the memory device. The write switch writes in the written data to the memory device while the pixel circuit is in transition of operation modes.
