Patent ID: 8098343

Claim:
A pixel unit, comprising: a first control circuit for controlling an output voltage of a first pixel region of the pixel unit, the first control circuit comprising: a first switching device; a first liquid crystal capacitor coupled to the first switching device; and a first storage capacitor coupled to the first switching device; and a second control circuit for controlling an output voltage of a second pixel region of the pixel unit, with the second pixel region and the first pixel region together constitute a spread area of the pixel unit, the second control circuit comprising: a second switching device; a second liquid crystal capacitor coupled to the second switching device; an auxiliary capacitor coupled to the second switching device; and a third switching device coupled to the second switching device through the auxiliary capacitors; wherein the output voltage of the first pixel region is different to the output voltage of the second pixel region, the first pixel region is a transmissive region, and the second pixel region is a reflective region.
