DATA SHEET TFT COLOR LCD MODULE NL6448BC20-08 17 cm (6.5 type), 640 × 480 pixels 262144 colors, high luminance, wide viewing angle DESCRIPTION NL6448BC20-08 is a TFT (thin film transistor) active matrix color liquid crystal display (LCD) comprising amorphous silicon TFT attached to each signal electrode, a driving circuit and a backlight. NL6448BC20-08 has a built-in backlight. Backlight includes long-life lamps and the lamps are replaceable. The 17 cm diagonal display area contains 640 × 480 pixels and can display 262144 colors simultaneously. NL6448BC20-08 is suitable for industrial application use, because the luminance is high, and the viewing direction is selectable with display scan select. FEATURES • High luminance (300 cd/m2, typ.) • Low reflection • Wide viewing angle with retardation film (Antiglare treatment) • Display reverse scan function • 6-bit digital RGB signals • Edge type backlight with long-life-lamps (Two lamp holders, inverter-less) • Variable luminance control • Recommended inverter (Part No. 65PWB31) • Compatible to the mounting holes position of NL6448AC20-06 except for inverter. APPLICATIONS • Measuring instruments • Display terminals for control system • Monitors for process controller Document No. EN0442EJ1V0DS00 (1st edition) Date Published July 1999 P Printed in Japan © 1999 NL6448BC20-08 STRUCTURE AND FUNCTIONS A color TFT (thin film transistor) LCD module is comprised of a TFT liquid crystal panel structure. LSIs for driving the TFT array, and a backlight assembly. The TFT panel structure is created by sandwiching liquid crystal material in the narrow gap between a TFT array glass substrate and a color filter glass substrate. After the driver LSIs are connected to the panel, the backlight assembly is attached to the backside of the panel. RGB (red, green, blue) data signals from a source system is modulated into a form suitable for active matrix addressing by the onboard signal processor and sent to the driver LSIs which in turn addresses the individual TFT cells. Acting as an electro-optical switch, each TFT cell regulates light transmission from the backlight assembly when activated by the data source. By regulating the amount of light passing through the array of red, green, and blue dots, color images are created with clarity. 2 Data Sheet EN0442EJ1V0DS00 NL6448BC20-08 BLOCK DIAGRAM H-driver · · · · · · 100 Ω R0-R5 1920 lines Digital signal processor G0-G5 Level shift 100 Ω V-driver B0-B5 47 Ω · · · · · TFT LCD panel 480 lines 100 Ω H: 640 × 3 (R, G, B) V: 480 CLK 100 Ω LCD timing controller H sync 100 Ω V sync VCC 47 kΩ 100 Ω DE DPS 47 kΩ VCC Power supply circuit LSIs (VCCi: 3.3 V) Drivers GND (SG) Frame (FG) Data Sheet EN0442EJ1V0DS00 3 NL6448BC20-08 (1) In case of use NEC recommended inverter Backlight VDDB Inverter (Part No. 65PWB31) BRTL BRTH GNDB (2) In case of use the inverter of customers Lamp VH VL VL VH Lamp Backlight OUTLINE OF CHARACTERISTICS (at room temperature) Display area 132.48 (H) × 99.36 (V) mm Drive system a-Si TFT active matrix Display colors 262144 Number of pixels 640 × 480 Pixel arrangement RGB vertical stripe Pixel pitch 0.207 (H) × 0.207 (V) mm Module size 178.8 (H) × 126.8 (V) × 11.0 typ.

Data Sheet EN0442EJ1V0DS00 19 NL6448BC20-08 GENERAL CAUTIONS Next figures and sentence are very important, please understand these contents as follows. CAUTION This figure is a mark that you will get hurt and/or the module will have damages when you make a mistake to operate. This figure is a mark that you will get an electric shock when you make a mistake to operate. This figure is a mark that you will get hurt when you make a mistake to operate CAUTION (1) Caution when taking out the module <1> Pick the pouch only, when taking out the module from a carrier box. (2) Cautions for handling the module <1> As the electrostatic discharges may break the LCD module, handle the LCD module with care against electrostatic discharges. <2> As the LCD panel and backlight element are made from fragile glass material, impulse and pressure to the LCD module should be avoided. <3> As the surface of polarizer is very soft and easily scratched, use a soft dry cloth without chemicals for cleaning. <4> Do not pull the interface connectors in or out while the LCD module is operating. <5> Put the module display side down on a flat horizontal plane. <6> Handle connectors and cables with care. <7> When the module is operating, do not lose CLK, Hsync, or Vsync signal. If any one or more of these signals is lost, the LCD panel would be damaged. <8> The torque for mounting screw should never exceed 0.20 N·m (2 kgf·cm). (3) Cautions for the atmosphere <1> Dew drop atmosphere must be avoided. <2> Do not store and/or operate the LCD module in high temperature and/or high humidity atmosphere. Storage in an electro-conductive polymer packing pouch and under relatively low temperature atmosphere is recommended. <3> This module uses cold cathod fluorescent lamps. Therefore, the life time of lamp becomes short conspicuously at low temperature. <4> Do not operate the LCD module in high magnetic field. (4) Caution for the module characteristics <1> Do not apply any fixed patterns data signal to the LCD module at product aging. Applying fixed pattern for a long time may cause image sticking. <2> This module has the retardation film which may cause the variation of the color hue in the different viewing angles. The ununiformity may appear on the screen under the high temperature operation. 20 Data Sheet EN0442EJ1V0DS00 NL6448BC20-08 (5) Other cautions <1> Do not disassemble and/or reassemble LCD module. <2> Do not readjust variable resistors nor switches etc. <3> When returning the module for repair or etc, pack the module not to be broken. We recommend the original shipping packages. Liquid Crystal Display has the following specific characteristics. There are not defects nor malfunctions. The display condition of the LCD module may be affected by the ambient temperature. The LCD module uses cold cathode tube for backlighting. Optical characteristics, like luminance or uniformity, will change during time. Uneven brightness and/or small spots may be noticed depending on different display patterns.

No license, either express, implied or otherwise, is granted under any patents, copyrights or other intellectual property rights of NEC Corporation or others. While NEC Corporation has been making continuous effort to enhance the reliability of its Electronic Components, the possibility of defects cannot be eliminated entirely. To minimize risks of damage or injury to persons or property arising from a defect in an NEC Electronic Components, customers must incorporate sufficient safety measures in its design, such as redundancy, fire-containment, and anti-failure features. NEC devices are classified into the following three quality grades: “Standard”, “Special”, and “Specific”. The Specific quality grade applies only to devices developed based on a customer designated “quality assurance program” for a specific application. The recommended applications of a device depend on its quality grade, as indicated below. Customers must check the quality grade of each device before using it in a particular application. Standard: Computers, office equipment, communications equipment, test and measurement equipment, audio and visual equipment, home electronic appliances, machine tools, personal electronic equipment and industrial robots Special: Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster systems, anti-crime systems, safety equipment and medical equipment (not specifically designed for life support) Specific: Aircrafts, aerospace equipment, submersible repeaters, nuclear reactor control systems, life support systems or medical equipment for life support, etc. The quality grade of NEC devices is “Standard” unless otherwise specified in NEC’s Data Sheets or Data Books. If customers intend to use NEC devices for applications other than those specified for Standard quality grade, DATA SHEET they should contact an NEC sales representative in advance. Anti-radioactive design is not implemented in this product.
