Liquid Crystal Display and Driving Method Thereof

A liquid crystal display (LCD), comprising:

• a gate driver, for outputting a plurality of gate signals successively;
• a data driver, for providing a plurality of data signals;
• and
• a pixel matrix, comprising a plurality of pixels coupled to the gate driver and the data driver, wherein each of the pixels receives a corresponding data signal according to a corresponding gate signal and each of the pixels comprises:
• a first sub-pixel, comprising:
• a first switch device, for outputting the corresponding data signal according to the corresponding gate signal;
• a first pixel electrode, coupled to the first switch device for receiving the data signal;
• a first electrode, for providing a first voltage;
• a first common electrode;
• and
• a first storage capacitor, formed between the first pixel electrode and the first common electrode;
• a second sub-pixel, comprising:
• a second switch device, for outputting the corresponding data signal according to the corresponding gate signal;
• a second pixel electrode, coupled to the second switch device for receiving the data signal;
• a second electrode, for providing a second voltage;
• a second common electrode;
• a second storage capacitor, formed between the second pixel electrode and the second common electrode;
• and
• a third storage capacitor, formed between the second common electrode and the second electrode;
• and
• a voltage coupling device, directly coupled to the first common electrode and the second common electrode such that the first common electrode is electrically related to the second common electrode.
