Logic
Dot clock input. (ECL level) Timing signal for display data.
Horizontal synchronous signal input (TTL level)
Vertical synchronous signal input (TTL level)
Red video signal input (0.7 Vp-p, 75
Green video signal input (0.7 Vp-p, 75
Blue video signal input (0.7 Vp-p, 75
Power control signal (TTL level)
“H” or “open” : Logic and LCD powers are on.
“L”
Display control signal in case of serial communications. (TTL level)
“H” or “Open”: Default
“L”
Serial communications are set up by external control.
Display control data (TTL level)
Detail of CNTDAT is mentioned in FUNCTIONS.
CLK for display control data (TTL level)
Detail of CNTCLK is mentioned in FUNCTIONS.
Latch pulse for display control data (TTL level)
Detail of CNTSTB is mentioned in FUNCTIONS.
Clamp function select signal (TTL level)
“H” or “Open”: Default
“L”
Clamp timing signal of black level (TTL level)
This mode works in CPSEL = “L.”
Luminance control signal (TTL level)
“H” or “Open”: Normal luminance
“L”
Backlight ON/OFF control signal (TTL level)
“H” or “Open”: Backlight on
“L”
Backlight luminance control-1
Variable resistor control (Note 2) or voltage control (Note 3)
These controls work in BRTP = “Open.”
Backlight luminance control-2 (TTL level)
BRTP signal control (Note 4)
Luminance control select signal (TTL level)
“H” or “Open”: Variable resistor control or voltage control
“L”
Contrast, brightness control signal (TTL level)
“H” or “Open”: Default
“L”
Serial communications are set up by external control.
Latch pulse2 for display control data
Detail of CNTDAT is mentioned in OSD FUNCTIONS.
OSD Red input (TTL level)
Detail of CNTDAT is mentioned in OSD FUNCTIONS.
OSD Green input (TTL level)
Detail of CNTDAT is mentioned in OSD FUNCTIONS.
