DATA SHEET
TFT COLOR LCD MODULE
NL128102AC28-01F
46 cm (18.1 inches), 1280 × 1024 pixels, full-color,
ultrawide viewing angle, multiscan function
built-in CRT interface board
DESCRIPTION
The NL128102AC28-01F is a TFT (thin film transistor) active-matrix color liquid crystal display (LCD) comprising
an amorphous silicon TFT attached to each signal electrode, a driving circuit, a CRT interface board, and a
backlight. NL128102AC28-01F has a built-in backlight with an inverter.
The 46 cm (18.1 inch) diagonal display area contains 1280 × 1024 pixels and can display fullcolor (more than 16
million colors simultaneously). Also, it has a wide viewing angle and multiscan function. Therefore, we call this
module Super Fine TFT.
The NL128102AC28-01F is the model with the CRT interface board which is mounted on NL128102AC28-01E.
FEATURES
• Ultrawide viewing angle (with lateral electric field)
• High luminance and low reflection
• CRT interface board
• Auto recognition of input signal (Analog RGB signals, sync on green, synchronous signals (Hsync, Vsync,
composite))
• Digital control: e.g., brightness, display position
• Free supply voltage sequence
• Corresponds to DDC1 and DDC2B
• Corresponds to VESA, DPMS
• Multiscan functions: e.g., SXGA, XGA, SVGA, VGA, VGA-TEXT, PC-9801, MAC SUN
• Incorporated direct type: backlight (eight lamps In the backlight unit, inverter)
• Backlight unit replacable (Part No. :181LHS03)
• On-screen display

NL128102AC28-01F
STRUCTURE AND FUNCTION
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 back side of the panel.
RGB (red, green, blue) data signals from a source system are modulated into a form suitable for active-matrix
addressing by the onboard signal processor and sent to the driver LSIs, which in turn address 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.
