Circuit
The
LCD-III can directly drive the liquid crystal display
panel
of
static, 1/2 duty factor, 1/3 duty factor and 1/4 duty
factor.
158
The LCD-III has 4 common signal tenninals and 32 segment
signal terminals. Further, if liquid crystal driver LSI
(H0441
OOH)
is connected
to
the LCD-III, up
to
96
segment signal terminals
can be extended externally. Thus, in addition
to
the internal
32
terminals, total 128 segment signal tenninals can be driven.
