LCD Drive Waveforms
The COM and SEG waveforms (AC signal waveforms for display) vary according to the duty (1/9, 1/12 and 1/17
duties). See 1) to 3) below.
The relationship between the duty ratio and the frame frequency is as follows:
Duty ratio
Frame Frequency
1/9
75.0 Hz
1/12
56.3 Hz
1/17
79.4 Hz
Note:
At an oscillation frequency (OSC) of 270 kHz
