B input
The pin through which the
OSD signal or analog
RGB is input.
(1) When inputting an
OSD signal, input the
ODS signal with a
voltage of 0 to 5 V
(4.1 V or more).
(2) When inputting an
analog RGB, input the
RGB signal via clamp
capacitor.
ACL works on this
input signal only when
the entire screen is
YS1-HI (the entire
screen: OSD).
21
YS1
Switches between the
internal RGB signal and
OSD/analog RGB (pin 18,
19, 20). When this switch
is on, the VSM output is
muted.
