NL3224AC35-06 data sheet en0229ej4v0ds00 5 1. outline 1.1 structure and principle NL3224AC35-06 module is composed of the amorphous silicon thin film transistor liquid crystal display (a-si tft lcd) panel structure with driver lsis for driving the tft (thin film transistor) array and a backlight unit. the a-si tft lcd panel structure is injected liquid crystal material into a narrow gap between the tft array glass substrate and a color-filter glass substrate. color (red, green, blue) data signals from a host system (e.g. pc, signal generator, etc.) are modulated into best form for active matrix system by a signal processing board, and sent to the driver lsis which drive the individual tft arrays. the tft array as an electro-optical switch regulates the amount of transmitted light from the backlight assembly, when it is controlled by data signals. color images are created by regulating the amount of transmitted light through the tft array of red, green and blue dots. 1.2 applications ? car navigation system ? display terminal for control system 1.3 features ? high luminance ? low reflection ? analog rgb signals ? select of pixel number (select function of vertical display line) ? reversible-scan direction ? edge light type

(shock: to be not greater 980m/s 2 and to be not greater 11ms, pressure: to be not greater 19.6n) 6.3 attentions 6.3.1 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. 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 0.18n ? 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. do not push-pull the interface connectors while the product is working, because wrong power sequence may break down the product.
NL3224AC35-06 data sheet en0229ej4v0ds00 30 6.3.2 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. 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. 6.3.3 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. 6.3.4 other all gnd, gndb, vcc 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.
