8. CAUTIONS ABOUT FRAME INVERSION

In the case of dot inversion, n frame last line and (n+1) frame first line is the same polarity.

When write the same polarity twice, there are two cases as follows.

(1) last line output in n frame > first line output in (n+1) frame

→ Possible to write

(2) last line output in n frame < first line output in (n+1) frame

→ Not possible to write

µPD16633B has charge buffer and discharge buffer, so need to inversion polarity and write in the case of both

ways.
