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

STRUCTURE AND FUNCTIONS
A color TFT (thin film transistor) LCD module is comprised of a TFT liquid crystal panel structure, LSIs for driving
the TFT array, and a backlight assembly. The TFT panel structure is created by sandwiching liquid crystal material
in the narrow gap between a TFT array glass substrate and a color filter glass substrate. After the driver LSIs are
connected to the panel, the backlight assembly is attached to the backside of the panel.
RGB (red, green, blue) data signals from a source system is modulated into a form suitable for active matrix
addressing by the onboard signal processor and sent to the driver LSIs which in turn addresses the individual TFT
cells.
Acting as an electro-optical switch, each TFT cell regulates light transmission from the backlight assembly when
activated by the data source. By regulating the amount of light passing through the array of red, green, and blue
dots, color images are created with clarity.
