When 1/2 duty is used, interconnect pins V
As the impedance of the built-in power supply split-resistance is large, it may not be suitable
for driving a large panel. If the display lacks sharpness when using a large panel, refer to
section 13.3.4, Boosting the LCD Drive Power Supply. When static or 1/2 duty is selected, the
common output drive capability can be increased. Set CMX to 1 when selecting the duty
cycle. In this mode, with a static duty cycle pins COM
and with 1/2 duty the COM
waveform is output from pins COM
