(shock: to be not greater 294m/s 2 and to be not greater 11ms, pressure: to be not greater 19.6n) 5.3 attentions 5.3.1 handling of the product take hold of both ends without touch the circuit board when customer pulls out products (lcd modules) from packing box. if customer touches it, products may be broken down or out of adjustment, because of stress to mounting parts. do not hook cables nor pull connection cables such as flexible cable and so on, for fear of damage. if customer puts down the product temporarily, the product puts on flat subsoil as a display side turns down. 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. the torque for mounting screws must never exceed 0.392n ? m. higher torque values might result in distortion of the bezel. do not press or rub on the sensitive display surface. if customer cleans on the panel surface, nec corporation recommends using the cloth with ethanolic liquid such as screen cleaner for lcd. do not push-pull the interface connectors while the product is working, because wrong power sequence may break down the product. data sheet en0545ej1v0d 58 NL128102AC31-02A 5.3.2 environment do not operate in dewdrop atmosphere and corrosive gases. do not operate or store in high temperature or high humidity atmosphere. keep the product in antistatic pouch in room temperature, because of avoidance for dusts and sunlight, if customer stores the product. do not operate in high magnetic field. circuit boards may be broken down by it. use an original protection sheet on the product surface (polarizer). adhesive type protection sheet should be avoided, because it may change color or properties of the polarizer. 5.3.3 characteristics the following items are neither defects nor failures. response time, luminance and color may be changed by ambient temperature. the lcd may be seemed luminance non-uniformity, flicker, vertical seam or small spot by display patterns. optical characteristics (e.g. luminance, display uniformity, etc.) gradually is going to change depending on operating time, and especially low temperature, because the lcd has cold cathode fluorescent lamps. do not display the fixed pattern for a long time because it may cause image sticking. use a screen saver, if the fixed pattern is displayed on the screen. the display color may be changed by viewing angle because of the use of condenser sheet in the backlight unit. the luminance may be changed by voltage variation (voltage drop), even if power source applies recommended voltage to backlight inverter. optical characteristics may be changed by input signal timings. 5.3.4 other all gnd, gndb, vdd and vddb terminals should be used without a non-connected line. do not disassemble a product or adjust volume without permission of nec corporation. see "replacement manual for backlight", if customer would like to replace backlight lamps. pay attention not to insert waste materials inside of products, if customer uses screwnails. pack the product with original shipping package, because of avoidance of some damages during transportation, when customer returns it to nec corporation for repair and so on. not only the module but also the equipment that used the module should be packed and transported as the module becomes vertical. otherwise, there is the fear that a display dignity decreases by an impact or vibrations. data sheet en0545ej1v0ds 59 NL128102AC31-02A 6. outline drawings

express, implied or otherwise, is granted under any patents, copyrights or other intellectual property rights of nec corporation or 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 component, 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. (note) (1) "nec" as used in this statement means nec corporation and also includes its majority-owned subsidiaries. (2) "nec electronic component products" means any electronic component product developed or manufactured by or for nec (as defined above). de0203 |
