(hereinafter called "NEC"). NEC 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 product described herein or any other liability arising from use of such application. No license, express, implied or otherwise, is granted under any patents, copyrights or other intellectual property rights of NEC or of others. While NEC has been making continuous effort to enhance the reliability of its products, the possibility of failures cannot be eliminated entirely. To minimize risks of damage to property or injury to person arising from a failure in an NEC product, customers must incorporate sufficient safety measures in their design, such as redundancy, fire-containment and anti-failure features. NEC products are classified into the following three quality grades: "Standard", "Special", "Specific" The "Specific" quality grade applies only to applications developed based on a customer designated "quality assurance program" for a specific application. The recommended applications of a product depend on its quality grade, as indicated below. Customers must check the quality grade of each application 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: Military systems, aircraft, aerospace equipment, submersible repeaters, nuclear reactor control systems, life support systems (medical equipment, etc.) and any other equipment The quality grade of this product is "Standard" unless otherwise specified in this document. If customers intend to use this product for applications other than those specified for "Standard" quality grade, they should contact NEC sales representative in advance.

Note2: The power supply lines (VDDB and GNDB) occurs large ripple voltage while luminance control of LCD lamps. There is the possibility that the ripple voltage produces acoustic noise and signal wave noise in audio circuit and so on. Put a capacitor (5,000 to 6,000F) between the power source lines (VDDB and GNDB) to reduce the noise, if the noise occurred in the circuit. 2.4 FUSE Parameter Type VDDB 11CT2A Fuse Supplier SOC Corporation 2.0A 72V 4.0A Note1 Rating Fusing current Remarks Note1: The power supply capacity should be more than the fusing current. If the power capacity is less than the fusing current, the fuse may not blow for a short time, and then nasty smell, smoking and so on may occur.

If customer connects wrongly, customer will be hurt and the module will be broken. DATA SHEET DOD-PD-0734 (2nd edition) 6 65PWB31 2.6 LUMINANCE CONTROL Method * Adjustment The variable resistor (R) for luminance control should be 10k 5%, B curve, 1/10W. Minimum point of the resistor is the minimum luminance. Also maximum point of the resistor is the maximum luminance. Adjustment and luminance ratio Resistor control BRTH R BRTL * Luminance ratio Resistance 0 10 k * Adjustment Luminance ratio 30% (min.) Note1 100% (max.) Voltage control method works, when BRTL terminal is 0V and BRTH voltage is input between BRTL and BRTH terminal. This control method can carry out continuation adjustment of luminance. Luminance is maximum when BRTH terminal is Open. Less than 0.5V causes backlight off. Except NL6448AC20-06 Voltage control Between the terminals of BRTL and BRTH Less than 0.5V 0.5V to 1.5V Luminance control range 1.5V 2.3V Backlight off Unstable operations such as flicker may occur. Luminance ratio Don't use. IC will be damaged. 30% (min.) 100% (max.) Note1 More than 2.5V Note1: These data are the target values. 3. RELIABILITY TEST This test is in accordance with the adaptable LCD module. Refer to Reliability Test of the LCD module. DATA SHEET DOD-PD-0734 (2nd edition) 7 65PWB31 4. PRECAUTIONS 4.1 MEANING OF CAUTION SIGNS The following caution signs have very important meaning. Be sure to read "4.2 CAUTIONS" and "4.3 ATTENTIONS", after understanding these contents! ! This sign has the meaning that customer will be injured by himself or the product will sustain a damage, if customer has wrong operations. This sign has the meaning that customer will get an electrical shock, if customer has wrong operations. This sign has the meaning that customer will be injured by himself, if customer has wrong operations. 4.2 CAUTIONS Do not touch the inverter while the inverter is working, because there is a danger that customer will get an electric shock. Do not remove the inverter protection sheet, because there is a danger that customer will get an electrical shock. Be sure to wait some time after turning power OFF before starting replacement work, because the inverter is charged at a high voltage after working. Be sure to wait some time after turning power OFF before starting replacement work, because the inverter is hot after working. Do not shock the inverter, because there is a danger of breaking. 4.3 ATTENTIONS ! 4.3.1 Handling of the product Take hold of both ends without touch the mounting parts when customer pulls out products from packing box. If customer touches it, products may be broken down or out of adjustment, because of stress to mounting parts. Take the measures of electrostatic discharge such as earth band, ionic shower and so on, when customer deals with the product, because products may be damaged by electrostatic. Do not push-pull the interface connectors while the product is working, because wrong power sequence may break down the product. Do not hook cables nor pull connection cables such as lamp cable and so on, for fear of damage. Properly connect the adaptable plug (backlight side) to socket (inverter side) without incomplete connection. After connecting, be careful not to hook the lamp cables because incomplete connection may occur by hooking the lamp cables. This incomplete connection may cause abnormal operation of high voltage circuit. DATA SHEET DOD-PD-0734 (2nd edition) 8 65PWB31 4.3.2 Environment Do not operate or store in high temperature, high humidity, dewdrop atmosphere or corrosive gases. Keep the product in antistatic pouch in room temperature, because of avoidance for dusts and sunlight, if customer stores the product. In order to prevent dew condensation occurring by temperature difference, the product packing box should be opened after leave under the environment of an unpacking room temperature enough. Because a situation of dew condensation occurring is changed by the environmental temperature and humidity, evaluate the leaving time sufficiently. (Recommendation leaving time: 6 hour or more with packing state) Do not operate in high magnetic field. Product may be broken down by it. This product is not designed as radiation hardened. 4.3.3 Other All GNDB and VDDB terminals should be used without any non-connected lines. Do not disassemble a product without permission of NEC. Pack the product with original shipping package, because of avoidance of some damages during transportation, when customer returns it to NEC. Put the spacer of 1.0mm thickness or more on a product rear side, because of the protection for contortion. e.g., Washer condition: The washer thickness = 1.0mm (min.) The washer diameter () = 5.0mm (Recommendation) DATA SHEET DOD-PD-0734 (2nd edition) 9 65PWB31 5. OUTLINE DRAWINGS (Unit: mm) DATA SHEET DOD-PD-0734 (2nd edition) 10 |
