TFT COLOR LCD MODULE
NL6448BC33-31D
26 cm (10.4 inches), 640 ´ 480 pixels, 262,144 colors,
Incorporated two-lamp/Edge-light type backlight
Wide viewing angle
DESCRIPTION
NL6448BC33-31D 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 and a backlight. NL6448BC33-31D has a
built-in backlight. Backlight includes long-life-lamps and the lamps are replaceable.
The 26cm (10.4 inches) diagonal display area contain s 640 ´ 480 pixels and can display 262,144 colors
simultaneously.
NL6448BC33-31D is suitable for industrial application use, because the viewing angle is wide and the luminance
is high. The viewing direction is also selectable either upper or lower side by changing scan direction.
NL6448BC33-31D is a Anti-Glare polarizer surface version of NL6448BC33-31.
FEATURES
• Anti-Glare surface on polarizer
• Wide viewing angle (with Retardation Film)
• High luminance (350 cd/m2, TYP.)
• Low reflection
• 6-bit digital RGB interface
• Data enable (DE) function
• Incorporated edge type backlight with two long-life-time lamps (one lamp holder)
• Lamp holder replaceable (Type No.: 104LHS31)
• Reversible scan direction (with DPS terminal or SW1 switch)
• Best viewing angle select function (with MVA terminal)
APPLICATIONS
• Display terminals for control system
• Monitors for process controller
• Personal computers (PC), Word processor

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.
