Figure 9 Flame inversion Drive
Operating of the Off-set level cancellation circuits
The internal signal INTFRM is generated by sampling from synchronized signal FRM at CL1 rising edge.
The internal counter counts the rising edge of internal signal INTFRM and the following operation shown
in Fig.10 is performed in every 4 frame cycle.
The first and second frame is the ordinary dot by dot inversion drive. The 3rd and 4th frame inverts the
polarity of voltage deviation of output terminal. This 4 frame cycle operation cancels voltage deviation
added to each dot and establishes the high quality display.
