NL3224BC35-21 data sheet dod-pd-0638 (1st edition) 4 1. outline 1.1 structure and principle color lcd module NL3224BC35-21 is composed of th e amorphous silicon thin film transistor liquid crystal display (a-si tft lcd) panel structure wi th driver lsis for driving the tft (thin film transistor) array and a backlight. 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 circuit, 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 application ? for industrial use 1.3 features ? high luminance ? wide color gamut ? wide viewing angle ? low reflection ? 6-bit digital rgb signals ? reversible-scan direction ? edge light type (without inverter) ? replaceable lamp for backlight www.datasheet.co.kr datasheet pdf - http://www..net/

(shock: to be not greater 980m/s 2 and to be not greater 11ms, pressure: to be not greater 19.6 n) 6.3 attentions 6.3.1 handling of the product take hold of both ends without touch the circuit board cover 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 lamp 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 su ch as earth band, ionic shower and so on, when customer handles the product, because products may be damaged by electrostatic. the torque for mounting screws must never exceed 0.29n ? m. higher torque values might result in distortion of the bezel. the product must be installed using mounting holes without undue stress such as bends or twist (see outline drawings). and do not add undue stress to any portion (such as bezel flat area) except mounting hole portion. bends or twist described above and undue stress to any portion except mounting hole portion may cause display un-uniformity. do not press or rub on the sensitive display su rface. if customer clean on the panel surface, nec recommends using the cloth with ethanolic liquid such as screen cleaner for lcd. ! www.datasheet.co.kr datasheet pdf - http://www..net/
NL3224BC35-21 data sheet dod-pd-0638 (1st edition) 26 do not push-pull the interface connectors while the product is working, because wrong power sequence may break down the product. do not bend or unbend the lamp cable at the near part of the lamp holding rubber, to avoid the damage for high voltage side of the lamp. this damage may cause a lamp breaking and abnormal operation of high voltage circuit. if the lamp cable is attached on the metal part of the lcd module directly, a leak high frequency current to the metal part may occur, then the br ightness may decrease or the lamp may not light. ? when not connecting shield plate of the lcd module to the customer's equipment ground, inverter noise may create a beat frequency that w ill cause video noise on the lcd screen. ? when customer handles the product, use of an original protection sheet on the product surface (polarizer) is recommended for protection of prod uct surface. adhesive type protection sheet may change color or properties of the polarizer. 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. in order to prevent dew condensation occurring by temperature difference, the product packing box must be opened after leave under the environment of an unpacking room temperature enough. because a situation of dew condensation occurring is changed by the envi ronmental 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. circuit boards may be broken down by it. this product is not designed as radiation hardened. 6.3.3 characteristics the following items are ne ither defects nor failures. response time, luminance and color may be changed by ambient temperature. the lcd may be seemed luminance non-uniformity, f licker, 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 angl e because of the use of condenser sheet in the backlight. 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 backli ght inverter may appear on a display. set up luminance control frequency of backlight inverter so that the interference noise does not appear. 6.3.4 other all gnd and vcc terminals should be used without any non- connected lines. do not disassemble a product or adjust variable resistors without permission of nec. see "replacement manual for lamp holder set", if customer would like to replace backlight lamps. pay attention not to insert waste materials insi de of products, if customer uses screwnails. pack the product with original shipping packag e, because of avoidance of some damages during transportation, when customer returns it to nec for repair and so on. www.datasheet.co.kr datasheet pdf - http://www..net/
