DATA SHEET
TFT COLOR LCD MODULE
NL128102AC28-01A
46 cm (18.1 inches), 1280 × 1024 pixels,
Full-color, Multi-scan function,
Ultra-wide viewing angle
DESCRIPTION
NL128102AC28-01A is a TFT (thin film transistor) active matrix color liquid crystal display (LCD) comprising
amorphous silicon TFT attached to each signal electrode, a driving circuit, a CRT interface board and a backlight.
NL128102AC28-01A has a built-in backlight with an inverter.
The 46 cm (18.1 inches) diagonal display area contains 1280 × 1024 pixels and can display full-color (more than
16 million colors simultaneously). Also, it has ultra wide viewing angle and multi-scan function. Therefore, this
module calls Super Fine TFT.
FEATURES
• Ultra-wide viewing angle and low reflection
• High luminance
• CRT interface board
• Auto recognition of input signal
Analog RGB signals, Sync on Green, Synchronous
signals (HS, Vsyn. Composite)
• Digital control: e.g. Brightness, Display Position
• Free supply voltage sequence
• Corresponding to DDCI and DDC2B
• Corresponding to VESA DPMS
• Multi-scan function: e.g. SXGA, XGA, SVGA, VGA,
VGA-TEXT, PC-9801, MAC, SUN
• Incorporated edge type backlight (Eight lamps into a
lamp unit, Inverter)
• Lamp unit replaceable (Part No.: 181LHS01)
• UL1950 3rd ed. CAN/CSA-C22.2 No.950-95
• On Screen Display
Regarding the use of OSD, please note that there is
possibility of conflicts with a patent in Europe and the
U.S.
Thus, if such conflict might happen when you use
OSD, we shall not be responsible for any trouble.
VESA : Video Electronics Standards Association
DPMS : Display Power Management Signaling
DDC1 : Display Data Channel 1
DDC2B: Display Data Channel 2B
APPLICATIONS
• Engineering workstation (EWS), Desk-top type of PC
• Display terminals for control system
• Monitors for process controller
