The RMS voltage at the intersection of BP1 and FPx of
Using V
will be
Thus, the segment at the intersection of BP1 and FPx should be turned off.
As another example, the waveforms for FP2 data to display the character A are shown in
The differential voltage for the BP4-FP2 pixel is shown.

LL5
= 5.0 V and V
The difference in on and off voltages is only 0.258 V in this example. Only
the “active” time voltage determines the difference between the on and off
voltage. The voltages during the non-active time always contribute the
same amount to the total RMS voltage.
