LCD Drive Waveforms
The COM and SEG waveforms (AC signal waveforms for display) vary according to the duty (1/9 and 1/17 duties).
See 1) and 2) below.
The relationship between the duty ratio and the frame frequency is as follows:
Duty ratio
1/8
1/9
1/16
1/17
Note: At an oscillation frequency (OSC) of 270 kHz
