NL10276BC30-17 preliminary data sheet dod-pd-0568 (1st edition) 4 1. outline 1.1 structure and principle color lcd module NL10276BC30-17 is composed of the 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 pr ocessing 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. co lor images are created by regulating the amount of transmitted light through the tft array of red, green and blue dots. 1.2 applications ? for industrial use 1.3 features ? ultra-wide viewing angle (adoption of super advanced -super fine tft (sa-sft)) ? lvds interface (8-bit) ? selectable lvds input map ? wide color gamut ? high contrast ? small foot print ? edge light type backlight (without inverter) ? replaceable lamp for backlight

"vs" and "vblh" are the voltage value between low voltage side (cold) and high voltage side (hot). note3: the asymmetric ratio of working waveform for lamps (lamp voltage peak ratio, lamp current peak ratio and waveform space ratio) should be less than 5 % (see the following figure.). if the waveform is asymmetric, dc (direct current) element apply into the lamp. in this case, a lamp lifetime may be shortened, because a distribution of a lamp enclosure substance inclines toward one side between low voltage terminal (cold terminal) and high voltage terminal (hot terminal). when designing the backlight inverter, evaluate asymmetric of lamp working waveform sufficiently. pa: supply voltage/current peak for positive, pb: supply voltage/current peak for negative sa: waveform space for positive part, sb : waveform space for negative part note4: in case "fo" is not the recommended value, beat noise may display on the screen, because of interference between "fo" and "1/th". recommended value of "fo" is as following. th: horizontal signal period (see " 4.9.2 timing characteristics ".) n: natural number (1, 2, 3 ???????? ) note5: method of lamp cable installation may invite fluctuation of lamp current and voltage or asymmetric of lamp working waveform. when designing method of lamp cable installation, evaluate the fluctuation of lamp current, voltage and working waveform sufficiently. pa pb sa sb 0 ? ? ? ?

NL10276BC30-17 preliminary data sheet dod-pd-0568 (1st edition) 24 6. precautions 6.1 meaning of caution signs the following caution signs have very important meaning. be sure to read "6.2 cautions" and "6.3 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. 6.2 cautions ? do not touch the working backlight. customer will be in danger of an electric shock. ? do not touch the working backlight. cust omer will be in danger of burn injury. ? do not shock and press the lcd panel a nd the backlight! there is a danger of breaking, because they are made of glass. (shock: to be not greater tbd m/s 2 and to be not greater tbd ms, pressu re: to be not greater tbd 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 deals with the product, because products may be damaged by electrostatic. the torque for mounting scre ws must never exceed tbd n ? 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.
NL10276BC30-17 preliminary data sheet dod-pd-0568 (1st edition) 25 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. when installing the lamp cable, do not attach the lamp cable on the metal part of the lcd module directly. this may cause leakage high frequency current to the metal part, then the brightness may decrease or the lamp may not light. ? when not connecting fg of the lcd module to the customer's equipment ground, inverter noise may create a beat frequency that will cause video noise on the lcd screen. ? when customer deals with the product, use of an original protection sheet on the product surface (polarizer) is recommended for protection of pa nel 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 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. 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, 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. 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. 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 package, because of avoidance of some damages during transportation, when customer returns it to nec for repair and so on. the lcd module by itself or integrated into end product should be packed and transported with display in the vertically position. otherwise the display characteristics may be impaired.
