NL10276AC28-01E
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.

POWER SUPPLY (1) Supply Sequence
VDD Voltage Logic signals Note
T1ime 200 ms< 0 ms<
Note Synchronous signal, Control signals and CLK CAUTION Wrong power sequence may damage to the module. (a) Logic signals (synchronous signals and control signals) should be "0" voltage (V), when VDD is not input. If higher than 0.3 V is input to signal lines, the internal circuit will be damaged. (b) LCD module will shut down the power supply of driving voltage to LCD panel internally, when one of CLK, Hsync, and Vsync, DE (at DE mode) is not input more than 90 ms typically. As the display data are unstable in this period, the display is disordered. But the backlight works correctly event this period. So the backlight ON/OFF should be controlled by BRTC signal. (c) The ON/OFF switching of backlight while logic signals are supplied. The backlight power supply (VDDB) is not related to the power supply sequence. However, unstable data will be displayed when the backlight power is turned ON/OFF with no logic signals. (d) Keep POWC signal "L" more than 200 ms after the power supply (VDD) is input, if POWC signal is controlled. (e) Analog RGB input are independent from this power supply sequence. (f) The power supply of backlight VDDB should be the rated voltage witin 80ms after turn-on. Otherwise, the protection circuit makes the backlight turn off. (2) Ripple of supply voltage Please note that the ripple at the input connector of the module should be within the values shown below. If the ripple would be beyond these values, the noise might appear on the screen. VDD (for Logic and LCD driver) Acceptable range Note < 100 mVp-p VDDB (for Backlight) < - 200 mVp-p
A coaxial cable shield should be connected with GND.

(3) Inverter Current Waveform In the luminance control mode, the rush current below flows into the inverter of the module. The duty cycle varies from 100% through 30% depending on the luminance control level. This might cause the noise on the screen. Please evaluate the appropriate value of the capacitor in the filter to eliminate the noise.

Please set up a preferable display position. See the following references. <1> Variation of CLK delay by temperature drift. (as reference) The temperature constant of CLK delay is 0.2 %/C. Calculated example: In case of delay time is 20 ns at Ta = 25 C; (a) In case Ta rising to 50 C. Increase of delay time (50 C n 25 C) x 0.002 x 20 ns = +1 ns So, the total delay time is 21 ns at Ta = 50 C. (b) In case Ta falling to 0 C. Decrease of delay time ( 0 C n 25 C) x 0.002 x 20 ns = n1 ns So, the total delay time is 19 ns at Ta = 0 C. <2> Variation of CLK delay time against each LCD module. (as reference) n10.5 % to +14.4 %

EXPANSION FUNCTION HOW TO USE EXPANSION MODE Expansion mode is a function to expand screen. For example, VGA signal has 640 480 pixels. But, if the display data can expanded to 1.6 times vertically and horizontally, VGA screen image can be displayed fully on the screen of XGA resolution. This LCD module has the function of expanding vertical direction as shown in Table 1. And expanding horizontal direction is possible by setting input CLK frequency which is equivalent to the magnification. It is necessary to make this CLK outside of this LCD module. The below image is display example, when DE function is default and HD and VD is set to most suitable frequency. And when DE function is used, HD and VD become default. Adjustment the display to the best position by DE signal. Please adopt this mode after evaluating display quality, because the appearance of expansion mode is happened to become bad some cases.

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 <1> Pick the pouch only, in taking out module from a carrier box. (2) Caution 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 of these signals is lost, the LCD panel would be damaged. <8> The torque of mounting screw should be 0.392 N*m (4 Kgf*cm) less. (3) Caution for the atmosphere <1> Dew drop atmosphere should be avoided. <2> 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.

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.
