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

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.

<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).

a mistake to operate.

(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.

(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.

NEC Corporation assumes no responsibility for any errors which may appear in this document. NEC Corporation does not assume any liability for infringement of patents. Copyrights or other intellectual property rights of third parties by or arising from use of a device de scribed h erein or any other liability arising from use of such device. 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 a s redundancy, fire-containment, and anti-failure features. NEC devices are classified into the following three q uality grade s: “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 m edica l equipment (not specifically designe d for life s upport) 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 otherwis e spe cified i n NEC ’s Data Sheets or D ata Books. If customers intend to use NEC devices for applications other than those specified for Standard quality grade, they should contact an NEC sales representative in adv ance. Anti-radioactive design is not implemented in this produ ct.
