Abstract: In a liquid crystal display, an image-defining data voltage is simultaneously applied to a main pixel electrode (MPE) and an electrically isolatable sub pixel electrode (SPE) to thereby respectively define a main pixel voltage and a sub pixel voltage. The MPE defines one plate of a first capacitor whose other plate receives a first common voltage whose voltage level can be varied after the image-defining data voltage is applied. Thus the main pixel voltage is shifted up or shifted down according to the voltage variation of the first common voltage. The SPE defines one plate of a second capacitor whose other plate receives a second common voltage. By causing the main pixel voltage to be of greater absolute amplitude than the sub pixel voltage, a side visibility of the liquid crystal display can be enhanced.

Abstract: An additional capacitor (“sharing capacitor”) is provided for each pixel of a liquid crystal display to store the previous voltage on the pixel electrode (i.e. the voltage obtained in the previous frame). At an opportune time after the pixel electrode has begun to charge for the current frame, the sharing capacitor's electrode is coupled to the pixel electrode to combine the pixel electrode's voltage with the sharing capacitor's voltage. As a result, the pixel electrode's voltage is changed to take into account the previous voltage so as to increase the liquid crystal's response speed. More particularly, the sharing capacitor's voltage changes the pixel voltage to provide a greater voltage overshoot or undershoot when the pixel color is changed a lot, so as to increase the liquid crystal response time. Therefore, greater response speed is provided at low power.

Abstract: In a display panel, main and sub pixel electrodes are connected to first and second drain electrodes of a thin film transistor, respectively, to receive a data voltage during a 1 H period as main and sub pixel voltages. A main storage electrode overlaps the main pixel electrode to receive a first common voltage that varies with the gate pulse and the polarity of the data voltage. A sub storage electrode overlaps the sub pixel electrode to receive a second common voltage that is uniformly maintained at a constant voltage level. The sub pixel voltage is uniformly maintained by the second common voltage, but the main pixel voltage is shifted up or down by the first common voltage. Thus, the main pixel voltage may have a voltage level higher than that of the sub pixel voltage.
