OUTLINE 1.1 STRUCTURE AND PRINCIPLE NL10276BC30-10 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. 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 * Monitor for PC 1.3 FEATURES * LVDS interface * Selectable LVDS input map * Wide color gamut * High contrast * Edge light type * Replaceable lamp for backlight (Inverter less) PRELIMINARY DATA SHEET DOD-M-1297 (4th edition) 4 NL10276BC30-10 2.

Note3 Note2,Note3 Ta = 0C Note2, Note3 Ta = 25C Note2, Note3 Note4 Note1: This product consists of 2 backlight lamps, and these specifications are for each lamp. Note2: The lamp voltage cycle between lamps should be kept on a same phase. "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 design the backlight inverter, evaluate asymmetric of lamp working waveform sufficiently. Pa 0 Pb Sa Sb Pa - Pb x 100 5 % Pb Sa - Sb x 100 5 % Sb 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".

When design the backlight inverter, evaluate the fluctuation of lamp current and voltage or asymmetric of lamp working waveform sufficiently.

If the power supply capacity is less than the fusing current, the fuse may not blow for a short time, and then nasty smell, smoking and so on may occur.

Note2: Display signals (D0+/-, D1+/-, D2+/- and CK+/-) and function signal (MSL) must be "0" voltage, exclude the VALID period (See above sequence diagram). If these signals are higher than 0.3V, the internal circuit is damaged. If some of display and function signals of this product are cut while this product is working, even if the signal input to it once again, it might not work normally. If customer stops the display and function signals, they should be cut VCC. Note3: VCC should be 2.5V or more while VCC ON period. Note4: The backlight power supply voltage should be inputted within the valid period of display and function signals, in order to avoid unstable data display.

PRECAUTIONS 6.1 MEANING OF CAUTION SIGNS The following caution signs have very important meaning. Be sure to read "6.2 CAUTIONS", after understanding this contents! 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 lamp cables while turn on. Customer will be in danger of an electric shock. Pay attention to burn injury for the working IC! Do not shock and press the LCD panel and the backlight lamp! There is a danger of breaking, because they are made of glass. (Shock: To be not greater 294m/s2 and to be not greater 11ms, Pressure: To be not greater 19.6N) 4 6.3 ATTENTIONS 6.3.1 Handling of the product x 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. y Do not hook cables nor pull connection cables such as flexible cable and so on, for fear of damage. z 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 0.34Nm. 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 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. Do not bend lamp cables from the foundation of the lamp holder, cables may break and the lamp may not light. Operation abnormality of the high-voltage circuit may occur by breaking. 4 PRELIMINARY DATA SHEET DOD-M-1297 (4th edition) 24 NL10276BC30-10 6.3.2 Environment x 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. y 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) z 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. x Response time, luminance and color may be changed by ambient temperature. y The LCD may be seemed luminance non-uniformity, flicker, vertical seam or small spot by display patterns. z 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 x All GND and VCC terminals should be used without a non-connected line. y Do not disassemble a product or adjust volume without permission of NEC Corporation. z 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. 4 PRELIMINARY DATA SHEET DOD-M-1297 (4th edition) 25 NL10276BC30-10 4 7.
