NL10276AC28-01L
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.

Supply Voltage Sequence (1) Please note that the supply voltage must not be applied to the module while the control signals (SEL, UP, DOWN, EXIT, LEFT, RIGHT and RESET) are connected to GND. malfunction. (2) If the power supply voltage is applied while UP and DOWN are connected to GND, the input control signals become an ineffective mode. To reset this mode, turn off the power once and turn on the power while UP and DOWN are connected to GND. Then, the mode will be released. (3) Do not change MENUSEL setting while the module is operated. MENUSEL selection (Hierarchical type or Toggle type) is set when the power supply voltage is applied. (4) Inverter current wave Inverter current wave is as follows.

Notes 1: Even if the preset timing is entered, a little adjustment of the functions such as Horizontal period, CLKdelay and display position, are required. The adjusted values are memorized in every preset No. 2: This module recognizes the synchronous signals with near preset timing of the frequency of HS, Vsync, even in the case that the signals other than the preset timing were entered. For instance, the module shows the display with presetting number 6 in the case of the following conditions: 640 x 480 dot; HS: 37.861kHz; Vsync: 72.809 Hz. Please note that using out of the preset timings may cause wrong magnification ratio, unfitness of control functions or other improper displays. 3: The display color scale may be different between Sync on Green Input and the others. CONTROL FUNCTIONS (1) EXPANSION MODES Expansion mode is a function to expand the screen size in different resolutions. For example, VGA signal has 640 x 480 pixels. But, if the display data can be expanded to 1.6 times vertically and horizontally, VGA screen image can be displayed fully on the screen of XGA resolution. This module automatically recognizes the timing shown in "PRESET TIMING" as an expansion mode. Please adopt this mode after evaluating display quality, because the appearance in expansion mode may become bad in some cases. The followings show display magnifications for each mode.

In order to achieve the best picture quality, the above functions should be adjusted by setting SEL, UP, DOWN, LEFT, RIGHT, RESET and EXIT signals. Each adjusted value is memorized as soon as SEL is selected or time out mode is valid and the memorized values are not affected even if the power is switched off. But the selected value is not memorized in case where a selected mode is changed to another or the power is turned off before time out.

GENERAL CAUTIONS
Because next figures and sentences are very important, please understand these contents as follows.
This figure is a mark that you will get hurt and/or the module will have damages when you make a mistake to operate.
CAUTION
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
Do not touch an inverter - - on which is stuck a caution label - - while the LCD module is under the operation, because of dangerous high voltage.
(1) Caution when taking out the module Pick the pouch only, in taking out module from a carrier box. (2) Cautions for handling the module a) As the electrostatic discharges may break the LCD module, handle the LCD module with care against electrostaic discharges. b) c) As the LCD panel and backlight element are made from fragile glass material, impulse and pressure to the LCD module should be avoided. As the surface of polarizer is very soft and easily scratched, use a soft dry cloth without chemicals for cleaning. d) Do not pull the interface connectors in or out while the LCD module is operating. e) Put the module display side down on a flat horizontal plane. f) Handle connectors and cables with care. LCD panel would be damaged. h) The torque to mounting screw should never exceed 0.392 N*m (4 kgf*cm). (3) Cautions for the atmosphere a) Dew drop atmosphere should be avoided. b) Do not store and/or operate the LCD module in a high temperature and/or high humidity atmosphere. Storage in an electro-conductive polymer packing pouch and under relatively low temperature atmosphere, is recommended. c) This module uses cold cathod fluorescent lamps. Therefore, the life time of the lamps becomes short conspicuously at low temperature. d) Do not operate the LCD module in a high magnetic field. (4) Caution for the module characteristics a) Do not apply the fixed pattern for a long time to the LCD module at product againg. Applying fixed pattern for a long time may cause image sticking. g) When the module is operating, do not lose CLK, HS or Vsync signal. If any one of these signals is lost, the

NL10276AC28-01L
(5) Other cautions a) Do not disassemble and/or reassemble LCD module. b) Do not readjust any variable resistors, switches, etc. c) When returning the module for repair etc., please pack the module not to be broken. We recommend to the original shipping packages. Liquid Crystal Display has the following specific characteristics. malfunctions. The display condition of LCD module may be affected by the ambient temperature. The LCD module has cold cathode tube for backlight. Optical characteristics, like luminance or uniformity, will change during time. Uneven brightness and/or small spots may be noticed depending on different display patterns. There are neither defects nor

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 described herein 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 component, 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, they should contact an NEC sales representative in advance. Anti-radioactive design is not implemented in this product.
