OUTLINE 1.1 STRUCTURE AND PRINCIPLE NL10276BC20-04 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 * Display terminal for control system * Industrial PC 1.3 FEATURES * High luminance * Wide viewing angle * Extensive temperature * 6-bit digital RGB signals * Single link LVDS interface * Reversible-scan direction * Edge light type * Replaceable lamp for backlight unit (Inverter less) * Acquisition product for UL/c-UL (File number: E170632) DATA SHEET EN0555EJ4V1DS00 5 NL10276BC20-04 2.

"VS" and "VBLH" are the voltage value between low voltage side (Cold) and high voltage side (Hot). Note2: The asymmetric ratio of working waveform for lamps (Power supply voltage peak ratio, power supply 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). Pa Pa - Pb x 100 5 % Sa Pb 0 Sa - Sb x 100 5 % Sb Sb Pb 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 Note3: The lamp holder of this product contains two backlight lamps. The low voltage terminal of both lamps is connected to one contact point. Also above power supply current specification is one lamp duty. Therefore, this lamp holder becomes twice as many power supply current as above value on low voltage (Cold) line. The measurement for the power supply current value of one lamp should measure on high voltage (Hot) line to each lamp. 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. 1 1 x (2n-1) x FO = th 4 th: Horizontal synchronous cycle (See "4.9.3 Timing characteristics".) n: Natural number (1, 2, 3 ) DATA SHEET EN0555EJ4V1DS00 9 NL10276BC20-04 4.3.3 Power supply voltage ripple This product works, even if the ripple voltage levels are beyond the permissible values as following the table, but there might be noise on the display image.

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 (DA0+/-, DA1+/-, DA2+/- and CK+/-) with 100 (Characteristic impedance) and function (DPSR) signals must be Low or High-impedance, exclude the VALID period (See above sequence diagram), in order to avoid that internal circuits 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. 4.4.2 Sequence for backlight inverter (Option) Note2 Display and function signals Note1 VALID period VDDB Note1: These are display and function signals for LCD panel signal processing board. Note2: The backlight inverter voltage (VDDB) should be inputted within the valid period of display and function signals, in order to avoid unstable data display.

DATA SHEET EN0555EJ4V1DS00 19 NL10276BC20-04 4.10.2 Definition of contrast ratio The contrast ratio is calculated by using the following formula. Luminance of white screen Contrast ratio (CR) = Luminance of black screen 4.10.3 Definition of luminance uniformity The luminance uniformity is calculated by using following formula. Maximum luminance from to Luminance uniformity (LU) = Minimum luminance from to The luminance is measured at near the 5 points shown below. 171 512 853 126 384 640 4.10.4 Definition of response times Response time is measured, the luminance changes from "white" to "black", or "black" to "white" on the same screen point, by photo-detector. Ton is the time it takes the luminance change from 90% down to 10%. Also Toff is the time it takes the luminance change from 10% up to 90% (See the following diagram.).

Be sure to read "6.2 CAUTIONS", after understanding this contents! This sign has the meaning that customer will be injured by himself, if customer has wrong operations. 6.2 CAUTIONS Pay attention to burn injury for the working backlight! It may be over 35C from ambient temperature. Do not shock and press the LCD panel and the backlight! Danger of breaking, because they are made of glass. (Shock: To be not greater 539m/s2 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 0.29Nm. 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. 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. DATA SHEET EN0555EJ4V1DS00 22 NL10276BC20-04 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. 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, backlight inverter ground (GNDB), VCC and backlight inverter power supply voltage (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 LAMPHOLDER", if customer would like to replace backlight lamps. Pay attention not to insert waste materials inside of products, if customer uses screwnails. DATA SHEET EN0555EJ4V1DS00 23 NL10276BC20-04 7.
