DATA SHEET
TFT COLOR LCD MODULE
NL6448AC20-06
17 cm (6.5 type), 640 × 480 pixels
262144/4096 colors, incorporated edge-light type backlight
high brightness, inverter separated from module
DESCRIPTION
NL6448AC20-06 is a TFT(thin film transistor) active matrix color liquid crystal display(LCD) comprising amor-
phous silicon TFT attached to each signal electrode, a driving circuit and a backlight. NL6448AC20-06 has a built-
in backlight. Backlight includes long-life-lamps and its lamps are replaceable.
The 17cm diagonal display area contains 640 × 480 pixels and can display 4096 or 262144 colors simultane-
ously.
NL6448AC20-06 is suitable for industrial application use, because the luminance is high, and the viewing
direction is selectable by display scan select.
FEATURES
™ High luminance (200 cd/m2 Typ.: saturated value)
™ Low reflection
™ Wide viewing angle with retardation film
™ Display reverse scan function
™ 6-bit/4-bit digital RGB signals
™ Edge type backlight with long-life-lamps (Two lamp holders, inverter)
™ Variable luminance control
™ Backlight lamp holder (65LHS-3L) replaceable
™ Compatible to the mounting hole position of NL6448AC20-02 except for inverter.
APPLICATIONS
™ Measuring instruments
™ Display terminals for control system
™ New media
™ Control boards for NC machine
™ Monitor for process controller

∗1 The supply voltage for input signals should be the same as VCC.
∗2 Apply VDD within the LCD operation period. When the backlight turns on before LCD operation or the LCD operation turns
off before the backlight turns off, the display may momentarily become white.
∗3 When the power is off, please keep whole signals (Hsync, Vsync, CLK, DE, and DATA) low level or high impedance.

note 1 : VCC : All VCC terminals should be connected to 5.0 V.
note 2 : DPS : Normal scan is “L”or “Open”. And reverse scan is “H”.
note 3 : During the operation, do not change the operation mode : e. g. scan direction and 4/6-bit signal.
note 4 : Do not operate LCD module without input DE signal.
