OUTLINE 1.1 STRUCTURE AND PRINCIPLE NL10276AC30-07 module is composed of the driver LSIs for driving the TFT (Thin Film Transistor) array with an amorphous silicon thin film transistor liquid crystal display (a-Si TFT LCD) panel structure and a backlight. The a-Si TFT LCD panel structure is injected liquid crystal material into the narrow gap between a TFT array glass substrate and a color filter glass substrate. RGB (Red, Green, Blue) data signals from a source system are modulated into a form suitable for active matrix addressing by the onboard signal processor and sent to the driver LSIs which in turn address the individual TFT cells. Working as an electro-optical switch, each TFT cell regulates transmitted light from the backlight assembly when worked by the data source. Color images are created by regulating the amount of transmitted light through the array of red, green and blue dots. 1.2 APPLICATIONS 4 * FA monitor 1.3 FEATURES *Parallel 8bit interface (2 port) *Ultra-wide viewing angle (with lateral electric field) *Fast response time *High luminance *High contrast *Wide color gamut *Luminance control *Small foot print *Direct light type *Replaceable backlight unit and inverter NEC Corporation DOD-M-0433 5/31 2.

Response time is measured by photo-detector's out put level, when the luminance changes "black" to "white", or " black " to " white " on the same screen point. Ton is the time it takes the luminance to go from 10% to 90% on condition. Toff is the reverse of Ton (See the following diagram) White 100% 90% Luminance Black 10% 0% Toff Ton Note6: Luminance uniformity is calculated by using following formula.

PRECAUTIONS 6.1 MEANING OF CAUTION SIGNS The following caution signs have very important meaning. Be sure to understand following contents, respectively. ! CAUTION This sign has a meaning that customer will be injured himself and/or the module will sustain a damage, if he makes a mistake in operations. This sign has a meaning that customer will get an electric shock if he makes a mistake in operations. This sign has a meaning that customer will be injured himself if he makes a mistake in operations. 6.2 CAUTIONS Do not touch HIGH VOLTAGE PART of the inverter while turn on. Customer will be in danger of an electric shock. Pay attention to handling for the working backlight. It may be over 35C from ambient temperature. Do not shock and press the LCD panel and the backlight. There will be in danger of breaking, because they are made of glass. (Shock: To be not greater 294m/s2 (30G) and to be not greater 11ms, Pressure: To be not greater 19.6N (2kgf)) 6.3 ATTENTIONS (1) Handling the product When customer pulls out products from carton box, take hold of both ends without touch the circuit board. If customer touches it, products may be broken down and/or out of adjustment, because of stress to mounting parts. If customer places products temporarily, turn down the display side and place on a flat table. Handle products with care and avoid electrostatic discharge (e.g. Decrease with earth band, ionic shower, etc.), because products (LCD modules) may be damaged by electrostatic. The torque for mounting screws should never exceed 0.39Nm. Over torque may cause mechanical damage to the product. Do not press or friction, because LCD panel surface is sensitive. If customer will clean the product surface, NEC Corporation or their supplier will recommend using the cloth with ethanolic liquid. NEC Corporation DOD-M-0433 27/31 Do not push-pull the interface connectors while turn on, because wrong power sequence may break down the product. Connection cables such as flexible cable, and so on, are danger of damage. Do not hook cables nor pull them. (2) Environment Dewdrop atmosphere must be avoided. Do not operate and/or stores in high temperature and/or high humidity atmosphere. If customer store the product, keep in antistatic pouch in room temperature, because of avoidance for dusts and sunlight. Do not operate in high magnetic field. Circuit boards may be broken down by it. Use an original protection sheet on product surface (polarizer). Adhesive type protection sheet should be avoided, because it may change color and/or properties of the polarizer. (3) Specification for products Do not display the fixed pattern for a long time because it may cause image sticking. If the fixed pattern is displayed on the screen, use a screen saver. The product may be changed of color by viewing angle because of the use of condenser sheet for backlight unit. The product may be changed of luminance by voltage variation, even if power source applies recommended voltage to backlight inverter. Optical characteristics may be changed by input signal timings. (4) Other All GND, GNDB, VDD and VDDB terminals should be connected without a non-connected signal line. Do not disassemble a product and/or adjust volume. If customer would like to replace backlight lamps, see 'REPLACEMENT MANUAL FOR BACKLIGHT'. If customer use screwnails, pay attention not to insert waste materials in inside of products. When customer returns product for repair and so on, pack it with original shipping package because of avoidance of some damages during transportation. General specifications for the LCD The following items are neither defects nor failures. Response time, luminance and color gamut may be changed by ambient temperature. The LCD may be seemed luminance uniformity, flicker, vertical seam and/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.
