ABSTRACT:
A pixel driving circuit (400) receives a signal voltage VA from a column bus (403) and generates therefrom, a back plate electrode voltage VB which is approximately twice that of a signal voltage VA. Included in the pixel driving circuit (400) are three transistors (402, 407 and 408) and a storage capacitor (404). During a first time period, two of the three transistors turn on to charge up or discharge the storage capacitor to the signal voltage VA, while the third transistor (407) is turned off, and during a second time, the third transistor (407) is turned on to effectively double the voltage provided to the back plate electrode, while the other two of the three transistors are turned off.
