NL6448AC33-29
26 cm (10.4 inches), 640 x 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 x 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 * High luminance (250 cd/m2, typ.) * Low reflection * 6-bit digital RGB interface * Data enable (DE) function * Incorporated edge type backlight with lamps (Two lamps, with inverter) * Lamp holder replaceable (Type No.: 104LHS31) * Reversible scan direction * Variable luminance control * Easy to assemble a touch panel * No antiglare treatment
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.

Luminance
Black 10 % 0% t on t off
5. The luminance uniformity is calculated using following formula. Maximum luminance Minimum luminance The luminance is measured at near the five points shown below.

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 a mistake to operate.
CAUTION
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) c) As the LCD panel and backlight element are made from fragile glass material, impulse and pressure to the LCD module should be avoided. As the surface of polarizer is very soft and easily scratched, use a soft dry cloth without chemicals for 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. the LCD panel would be damaged. h) i) The torque to mounting screw should never exceed 0.294 N*m (3 kgf*cm). 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. g) When the module is operating, do not lose CLK, Hsync or Vsync signal. If any one of these signals is lost,

(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, they should contact an NEC sales representative in advance. Anti-radioactive design is not implemented in this product.
