NL6448AC33-29
26 cm (10.4 inches), 640 × 480 pixels, 262,144 colors,
Incorporated two-lamp/Edge-light type backlight
Ultra Wide viewing angle
DESCRIPTION
NL6448AC33-29 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. NL6448AC33-29 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.
NL6448AC33-29 is suitable for industrial application use, because the viewing angle is ultra wide and the
luminance is high. Also the viewing direction is selectable either upper or lower side changing scan direction.
FEATURES
• Ultra wide viewing angle with lateral electric field
• Lamp holder replaceable (Type No.: 104LHS31)
• High luminance (250 cd/m2, typ.)
• Reversible scan direction
• Low reflection
• Variable luminance control
• 6-bit digital RGB interface
• Easy to assemble a touch panel
• Data enable (DE) function
• No antiglare treatment
• Incorporated edge type backlight with lamps (Two
lamps, with inverter)
APPLICATIONS
• Display terminals for control system
• Monitors for process controller
• Industrial PC

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.

Open)
When DPS is VCC, reverse scan is selected even if SW1 is set at normal scan.
When DPS is GND, normal scan is selected even if SW1 is set at reverse scan.

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
CAUTION
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, in taking out 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 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 of these signals is lost,
the LCD panel would be damaged.
h)
The torque to mounting screw should never exceed 0.294 N·m (3 kgf·cm).
i)
Don’t push or rub the surface of LCD module.
If you do, the scratches or rubbing marks may be left there.
(3) Cautions for the atmosphere
a) Dew drop atmosphere should be avoided.
b) Do not store and/or operate the LCD module in a 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 lamp. Therefore, the life time of the lamp becomes short if the
module is operated in the low temperature environment.
d) Do not operate the LCD module in a high magnetic field.
(4) Caution for the module characteristics
a) Do not apply fixed pattern data signal for a long time to the LCD module. It may cause image sticking.
Please use screen savers if the display pattern is fixed more than one hour.
Data Sheet EN0439EJ1V0DS00
21
NL6448AC33-29
(5) Other cautions
a) Do not disassemble and/or reassemble LCD module.
b) Do not readjust variable resistors etc.
c)
When returning the module for repair or etc, please pack the module not to be broken. We recommend to
the original shipping packages.
Liquid Crystal Display has the following specific characteristics. There are not defects or malfunctions.
• The display condition of 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
customer designated “quality assurance program” for a specific application. The recommended applications of a
device depend on its quality grade, as indicated below. Customers must check the quality grade of each device
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,
