1. Summary
LH1538F2
2
The LH1538F2 is a 120 output common driver LSI suitable
for driving
large
scale dot matrix
LC panels using as low voltage
segment driving
method.
Through the use of SST (Super Slim TCP) technology.
it is ideal for
substantially
decreasing
the size of the frame section
of the LC module.
When combined with the LH1580 or LH1581 Segment Driver,
a low power consuming.
high-precision
LC panel display
can be assembled.
2. Features
