Dx
Used to input a start pulse for the X-shift register (component of
the
X
driver).
CLx,-CLXd
CLxt-CLx4
Used to input a transfer clock for the X-shift register (component
of the
X
driver). Composed of 4 clocks (45” shifted from each
other) and their 4 inverted signals.
VID-R,
VID-G
Used to input the video signal for the
X
driver. Polarity inverted
VID-B every 1

the
Y
driver).
CLYI,
CYY2
Used to input
a
transfer clock for the Y-shift register (component
of
they
driver) and its inverted signal.
CLy
and-CLy-to-be
inputted
to CLyl and
CLy2,
respectively, for forward shift, and
CLy
and
CLy
to be inputted to CLyl and
CLy2,
respectively, for reverse
shift.
