Abstract
In one embodiment, the present invention, one or more light modulating elements are controlled by a method comprising the following steps: controlling at least one pulse width using recursive feedback; and driving an electrode means using the pulse width to thereby control a light modulating element of an array of light modulating elements. In other embodiments, the present invention provides a method and system for determining a pulse wave form for each line of a two-dimensional array of drive bits using a recursive feedback process, wherein each drive bit in the array of drive bits is in an initialized state; and for turning all of the drive bits to an off state to thereby produce a blanking interval between fields for an image, wherein control of each of the pulse wave forms is staggered in time.
