1/3 Duty and 1/3 Bias
1/4 Duty and 1/3 Bias
Figure 23-4. Driving a LCD with Two Common Terminals
1/3 bias is usually recommended for LCD with three common terminals (1/3 duty). Waveform is
shown in
COM1 is the voltage across a segment that is off.
Figure 23-5. Driving a LCD with Three Common Terminals
1/3 bias is optimal for LCD displays with four common terminals (1/4 duty). Waveform is shown
in
the voltage across a segment that is off.
