TFT COLOR LCD MODULE
NL6448AC33-18A
26 cm (10.4 inches), 640 × 480 pixels, 262144 colors,
Luminance adjustable, Non anti-glare panel
DESCRIPTION
NL6448AC33-18A 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. NL6448AC33-18A has
a built-in backlight. Backlight includes long life lamps, which are replaceable.
The 26 cm diagonal display area contains 640 × 480 pixels and can display 262144 colors simultaneously.
NL6448AC33-18A is suitable for factory automation use, because luminance is higher, and viewing direction is
selectable by switching display scan direction.
FEATURES
• Reverse function (user set up)
• 6-bit digital RGB signals
• 3.3 V operation (5.0 V available)
• Data enable function (DE/Fixed mode select: user set up)
• Smooth polarizer surface (No antiglare treatment)
• Incorporated edge type backlight (Two lamps, with inverter, bright/dark selectable)
• Backlight tube replaceable (refer to the tube replace manual for NL6448AC33-18A)
APPLICATIONS
• Industrial PC
• Display terminals for control system
• Monitors for process controller

STRUCTURE AND FUNCTIONS
A TFT color LCD module comprises a TFT LCD panel, LSIs for driving liquid crystal, and the backlight. The
TFT LCD panel is composed of a TFT array glass substrate superimposed on a color filter glass substrate with
liquid crystal filled in the narrow gap between two substrates. The backlight apparatus is located on the backside
of the LCD 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.

GENERAL CAUTIONS
Next figures and sentence are very important, please understand these contents as follows.
This figure is a mark that you will get hurt and/or the module will have damages when you make
CAUTION
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
<1>
Pick the pouch only, when taking out the module from a carrier box.
(2) Cautions for handling the module
<1>
As the electrostatic discharges may break the LCD module, handle the LCD module with care against
electrostatic discharges.
<2>
As the LCD panel and backlight element are made from fragile glass material, impulse and
pressure to the LCD module should be avoided.
<3>
As the surface of polarizer is very soft and easily scratched, use a soft dry cloth without chemicals for
cleaning.
<4>
Do not pull the interface connectors in or out while the LCD module is operating.
<5>
Put the module display side down on a flat horizontal plane.
<6>
Handle connectors and cables with care.
<7>
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.
<8>
The torque for mounting screw should never exceed 0.294 N·m (3 kgf·cm).
(3) Cautions for the atmosphere
<1>
Dew drop atmosphere should be avoided.
<2>
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.
<3>
This module uses cold cathod fluorescent lamps. Therefore, the life time of lamp becomes short
conspicuously at low temperature.
<4>
18
Do not operate the LCD module in high magnetic field.
Data Sheet EN0497EJ1V0DS00
NL6448AC33-18A
(4) Caution for the module characteristics
<1>
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.
(5) Other cautions
<1>
Do not disassemble and/or reassemble LCD module.
<2>
Do not readjust variable resistors, switches, etc.
<3>
When returning the module for repair, etc. 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 in the progres of time.
Uneven brightness and/or small spots may be observed depending on different display patterns.

No part of this document may be copied in any form or by any means without the prior written consent of NEC
Corporation.
NEC Corporation does not assume any liability for infringement of patents, copyrights or other intellectual
property rights of third parties by or arising from use of a device described herein or any other liability arising
from use of such device. No license, either express, implied or otherwise, is granted under any patents,
copyrights or other intellectual property rights of NEC Corporation or of others.
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 quanlity grades:
"Standard", "Special", and "Specific". The Specific quanlity 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
system 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 speci fied for Standard quality grade,
they should contact an NEC sales representative in advance.
