15.6.2 Frontplane Waveform
The frontplane waveform is a periodic waveform that depends on the data to be displayed stored in the
RAM. For 32 backplanes that are multiplexed in time, each frontplane driver waveform will have 1/64 of
a frame period at V
and 1/64 of a frame period of V
that is off, as shown in
