摘要： A pixel structure includes a first sub-pixel and a second sub-pixel. The first sub-pixel includes a first switching transistor and a first liquid crystal capacitor, wherein when the first switching transistor is turned on, the first liquid crystal capacitor is biased to a first gray level voltage. The second sub-pixel includes a second switching transistor, a second liquid crystal capacitor, a third switching transistor, a charge sharing capacitor and a fourth switching transistor, wherein when the second switching transistor is turned on, the second liquid crystal capacitor is biased to the first gray level voltage; when the fourth switching transistor is turned on, the charge sharing capacitor is reset to a predetermined voltage; and when the third switching transistor is turned on, the second liquid crystal capacitor and the charge sharing capacitor are charge-shared to a second gray level voltage through the third switching transistor.
