(shock: to be not greater 294m/s 2 and to be not greater 11ms, pressure: to be not greater 19.6n) 19.3 attentions (1) handling of the product take hold of both ends without touch the circuit board when customer pulls out products (lcd modules) from inner packing box. if customer touches it, products may be broken down or out of adjustment, because of stress to mounting parts. 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 0.34n ? m. higher torque values might result in distortion of the bezel. do not press or rub on the sensitive display surface. if customer clean on the panel surface, nec corporation recommends using the cloth with ethanolic liquid such as screen cleaner for lcd.
nec corporation dod-m-1167 33/35 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 flexible cable and so on, for fear of damage. (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. 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. (3) characteristics 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. optical characteristics may be changed by input signal timings. the interference noise of input signal frequency for this product's signal processing board and luminance control frequency of customer's backlight inverter may appear on a display. set up luminance control frequency of backlight inverter so that the interference noise does not appear. the product may be changed of luminance by voltage variation, even if power source applies recommended voltage to backlight inverter. optical characteristics may be changed by input signal timings. (4) other all gnd, gndb, vdd and vddb terminals should be connected without a non-connected signal line. do not disassemble a product or adjust volume without permission of nec corporation. see "replacement manual for lampholder set", if customer would like to replace backlight lamps. pay attention not to insert waste materials inside of products, if customer uses screwnails. when customer returns product for repair and so on, pack it with original shipping package because of avoidance of some damages during transportation. 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."
