Abstract
A pixel circuitry of a display device is provided to make a voltage level transmitted to a display element be close to a voltage level of a received data voltage, such that the pixel circuitry faithfully transmits the data voltage to the display element. The pixel circuitry of a display device includes a first write switch, a first write memory unit, a first voltage following module, and a display element. The first voltage following module is to detect a first data voltage stored in the first write memory unit, and to generate a corresponding first output voltage at a terminal of the display element based on a detection result. A first output terminal of the first voltage following module is controlled by a switching voltage.
