DATA SHEET
TFT COLOR LCD MODULE
NL6448BC20-08
17 cm (6.5 type), 640 × 480 pixels 262144 colors,
high luminance, wide viewing angle
DESCRIPTION
NL6448BC20-08 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. NL6448BC20-08 has a
built-in backlight. Backlight includes long-life lamps and the lamps are replaceable.
The 17 cm diagonal display area contains 640 × 480 pixels and can display 262144 colors simultaneously.
NL6448BC20-08 is suitable for industrial application use, because the luminance is high, and the viewing
direction is selectable with display scan select.
FEATURES
• High luminance (300 cd/m2, typ.)
• Low reflection
• Wide viewing angle with retardation film (Antiglare treatment)
• Display reverse scan function
• 6-bit digital RGB signals
• Edge type backlight with long-life-lamps (Two lamp holders, inverter-less)
• Variable luminance control
DataSheet4U.com
• Recommended inverter (Part No. 65PWB31)
• Compatible to the mounting holes position of NL6448AC20-06 except for inverter.
APPLICATIONS
• Measuring instruments
• Display terminals for control system
• Monitors for process controller

DataShee
Note Colors are developed in combination with 6 bit signal (64 steps in grayscale) of each primary red, green,
and blue color.
This process can result in up to 262144 (64 × 64 × 64) colors.
