Improved methods for driving an active matrix of pixel electrodes controlled with thin film transistors when the voltage on a top electrode is being altered between driving frames. The methods described increase performance by providing smaller swings in the overall voltage between the top electrode and pixel electrode while reducing stress on the thin film transistor.
