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
Frame Frequency
1/8
84.4 Hz
1/9
75.0 Hz
1/16
84.4 Hz
1/17
79.4 Hz
Note: At an oscillation frequency (OSC) of 270 kHz
