Preliminary
component and can take only one of the two rms values.
20.8
LCD waveform generation is based on the philosophy
that the net AC voltage across the dark pixel should be
maximized and the net AC voltage across the clear
pixel should be minimized. The net DC voltage across
any pixel should be zero.
The COM signal represents the time slice for each
common, while the SEG contains the pixel data.
The pixel signal (COM-SEG) will have no DC
The higher rms value will create a dark pixel and a lower
rms value will create a clear pixel.
As the number of commons increases, the delta
between the two rms values decreases. The delta
represents the maximum contrast that the display can
have.
The LCDs can be driven by two types of waveforms:
Type-A and Type-B. In a Type-A waveform, the phase
changes within each common type, whereas a Type-B
waveform’s phase changes on each frame boundary.
Thus, Type-A waveforms maintain 0 V
frame, whereas Type-B waveforms take two frames.
Figure 20-7 through Figure 20-17 provide waveforms
for static, half-multiplex, one-third multiplex and quarter
multiplex drives for Type-A and Type-B waveforms.
