TFT COLOR LCD MODULE
NL6448BC33-31
26 cm (10.4 inches), 640 × 480 pixels, 262,144 colors,
Incorporated two-lamp/Edge-light type backlight
Wide viewing angle
DESCRIPTION
NL6448BC33-31 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. NL6448BC33-31 has a
built-in backlight. Backlight includes long-life-lamps and the lamps are replaceable.
The 26 cm (10.4 inches) diagonal display area contains 640 × 480 pixels and can display 262,144 colors
simultaneously.
NL6448BC33-31 is suitable for industrial application use because of the wide viewing angle and the high
luminance. Also, the viewing direction is selectable either upper or lower side by changing scan direction.
NL6448BC33-31 interface is compatible with NL6448AC33-18, -18A, -18B and -27.

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.

Notes 1. The contrast ratio is calculated by using the following formula.
Contrast ratio (CR) =
Luminance with all pixels in white
Luminance with all pixels in black
The Luminance is measured in darkroom.
2. The luminance is measured after 20 minutes from the module works, with all pixels in white. Typical
value is measured after luminance saturation.

Photodetector output signal is measured when the luminance changes “White” to “Black” . Response
time (ton) is the time between 10% and 100% of the photodetector output amplitude. Response time
(toff) is the time between 0% and 90% of the output amplitude.

GENERAL CAUTIONS
Next figures and sentence are very important. Please understand these contents as follows.
CAUTION
This figure is a mark that you will get hurt and/or the module will have damages when you make
a mistake to operate.
This figure is a mark that you will get an electric shock when you make a mistake to operate.
This figure is a mark that you will get hurt when you make a mistake to operate
CAUTIONS
Do not touch an inverter, on which is stuck a caution label, while the LCD module is under the operation, because
of dangerous high voltage.
(1) Caution when taking out the module
a) Pick the pouch only, when taking out the module from a carrier box.
(2) Cautions for handling the module
a) As the electrostatic discharges may break the LCD module, handle the LCD module with care against
electrostatic discharges.
b)
As the LCD panel and backlight element are made from fragile glass material, impulse and
c)
As the surface of polarizer is very soft and easily scratched, use a soft dry cloth without chemicals for
pressure to the LCD module should be avoided.
cleaning.
d) Do not pull the interface connectors in or out while the LCD module is operating.
e) Put the module display side down on a flat horizontal plane.
f)
Handle connectors and cables with care.
g) When the module is operating, do not lose CLK, Hsync or Vsync signal. If any one or more of these signals
is lost, the LCD panel would be damaged.
h) The torque for mounting screws should never exceed 0.294 N·m (3 kgf·cm).
(3) Cautions for the atmosphere
a) Dew drop atmosphere must be avoided.
b) Do not store and/or operate the LCD module in high temperature and/or high humidity atmosphere.
Storage in an electro-conductive polymer packing pouch and under relatively low temperature atmosphere
is recommended.
c)
This module uses cold cathod fluorescent lamps.
Therefore, the life time of lamp becomes short
conspicuously at low temperature.
d) Do not operate the LCD module in high magnetic field.
(4) Cautions for the module characteristics
a) Do not apply any fixed patterns data signal for a long time to the LCD module at product aging. It may
cause image sticking.
b) This module has the retardation film which may cause the variation of color hue in the different viewing
angles. The ununiformity may appear on the screen under the high temperature operation.
20
Data Sheet EN0443EJ1V0DS00
NL6448BC33-31
(5) Other cautions
a) Do not disassemble and/or reassemble LCD module.
b) Do not readjust variable resistors nor switches etc.
c)
When returning the module for repair or etc, please pack the module not to be broken. We recommend the
original shipping packages.
Liquid Crystal Display has the following specific characteristics. There are not defects nor malfunctions.
• The display condition of the LCD module may be affected by the ambient temperature.
• The LCD module uses cold cathode tube for backlighting. Optical characteristics, like luminance or
uniformity, will change during time.
• Uneven brightness and/or small spots may be noticed depending on different display patterns.

While NEC Corporation has been making continuous effort to enhance the reliability of its Electronic
Components, the possibility of defects cannot be eliminated entirely. To minimize risks of damage or injury to
persons or property arising from a defect in an NEC Electronic Components, customers must incorporate
sufficient safety measures in its design, such as redundancy, fire-containment, and anti-failure features.
NEC devices are classified into the following three quality grades:
“Standard”, “Special”, and “Specific”. The Specific quality grade applies only to devices developed based on a

before using it in a particular application.
Standard: Computers, office equipment, communications equipment, test and measurement equipment, audio
and visual equipment, home electronic appliances, machine tools, personal electronic equipment and industrial
robots
Special:
Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster
systems, anti-crime systems, safety equipment and medical equipment (not specifically designed for life support)
Specific: Aircrafts, aerospace equipment, submersible repeaters, nuclear reactor control systems, life support
systems or medical equipment for life support, etc.
The quality grade of NEC devices is “Standard” unless otherwise specified in NEC’s Data Sheets or Data Books.
If customers intend to use NEC devices for applications other than those specified for Standard quality grade,
