Figures 12, 13 and 14 show the LCD driving waveforms consisting of COM signal, SEG signal,

DF signal and L (latch pulse waveform) signal, in the duty of 1/8, 1/11 and 1/16 respectively.

The relation between duty and frame frequency is described in the table below.

(Note) The OSC oscillation frequency is assumed to be 250 kHz.
