Therefore it produces a proportionately
larger waveform to play with, giving even more latitude for changing the amplitude of the Top Ramp of Reset with the Set-up, ditto for the pitch of the Bottom Ramp for Reset with the Set_down.
From the full waveforms from Lg that I have seen the Vsc and Vzb are bias voltages applied to the address scan portion of the waveform to prevent misfiring pixels. They could be referring to the address period as the "complex waveform". The Vzb is also applied to the Z electrode during ramp down of the reset waveform.
Unless I see a full waveform for each specific model I can't even properly speculate what each V pot does regarding panel discharge and black level.
One speculation I would make is that since the reset portion of the waveform generates black level then any pot that controls voltage on any electrode during this waveform period should have a direct impact on the black level and pixel control. I've seen full waveforms where Set-down,Set-Up,Va,Vs,Vy,Vzb are all applied to the electrodes during reset.
Any pot that controls voltage outside this period primarily should affect pixel control and possibly indirectly affect black level by altering the wall charge entering the reset stage. I've seen waveforms where -Vy, Va, Vz, Vsc are applied only to the electrodes during address, and Va,Vz,Vy,-Vy,Vzb are applied to both the reset and address periods.
