LCD driver output
TheoutputnumberofthedeviceLCDdrivercanbe19 2
or 19 3 or 18 4 by options (i.e., 1/2 duty, 1/3 duty or 1/4
duty). The bias type of LCD driver can be R type (for
HT49R30A-1/HT49C30-1)or C type.Ifthe R bias type
is selected, no external capacitor is required. If the C
bias type is selected, a capacitor mounted between C1
and C2 pins is needed. The bias voltage of LCD driver
can be 1/2 bias or 1/3 bias by options.
