142. A method comprising:
-
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 said array of drive bits is in an initialized state; and
turning all of said drive bits to an off state to thereby produce a blanking interval between fields for an image, wherein control of each of said pulse wave forms is staggered in time.
