Pin
No.
Pin Name
Function
The pin through which the
OSD signal or analog
RGB is input.
18 Analog
OSD R
input
19 Analog
OSD G
input
20 Analog
OSD
B input
(1) When inputting an
OSD signal, input the
ODS signal with a
voltage of 0 to 5 V
(4.1 V or more).
18
(2) When inputting an
19
analog RGB, input the
RGB signal via clamp
20
capacitor.
ACL works on this
input signal only when
the entire screen is
YS1-HI (the entire
screen: OSD).
