Abstract
A pixel unit includes a first control circuit and a second control circuit and is divided into a first region and a second region. The first control circuit determines the output voltage of the first region and includes a first switching device, a first liquid crystal capacitor and a first storage capacitor coupled to the first switching device. The second control circuit determines the output voltage of the second region and includes a second switching device, a second liquid crystal capacitor and an auxiliary capacitor coupled to the second switching device, and a third switching device. The third switching device is coupled to the second switching device through the auxiliary capacitor, and the output voltage of the first region is different to that of the second region.
