PRELIMINARY DATA SHEET
TFT COLOR LCD MODULE
NL6448AC33-27G
26 cm (10.4 inches), 640 ´ 480 pixels, 262,144 colors,
Incorporated two-lamp/edge-light type backlight,
Wide viewing angle
DESCRIPTION
NL6448AC33-27G is a TFT (thin film transistor) active matrix color liquid crystal display (LCD) comprising
amorphous silicon TFT attached to each signal electrode, a d riving circuit and a backlight. NL6448AC33-27G has a
built-in backlight. Backlight includes replaceable, long-life cold cathode fluorescent lamps (CCFLs).
The 26 cm (10.4 inches) diagonal display area contains 640 ´ 480 pixels and can display 262,144 colors
simultaneously.
NL6448AC33-27G is suitable for industrial application use because it has wide viewing angle and high luminance.
The viewing direction (upper or lower side) is also selectable by changing the scan direction.
NL6448AC33-27G is a gamma-modified version of NL6448AC33-27.
FEATURES
• Wide viewing angle (with Retardation Film)
• High luminance (250 cd/m2 typ.)
• Low reflection
• 6-bit digital RGB interface
• Data enable (DE) function
• Incorporated edge-light type backlight with two long-life lamps (one lamp holder)
• Replaceable lamp holder (Type No.: 104LHS29L)
• Reversible scan direction
• Best viewing angle select function
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 comprises 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 LSIs drivers 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 f orm suitable for active matrix
addressing by the on-board signal processor and sent to the LSIs driver 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.
