1. OUTLINE
1.1 STRUCTURE AND PRINCIPLE
NL10276BC20-04 module is composed of the amorphous silicon thin film transistor liquid crystal
display (a-Si TFT LCD) panel structure with driver LSIs for driving the TFT (Thin Film Transistor) array
and a backlight unit.
The a-Si TFT LCD panel structure is injected liquid crystal material into a narrow gap between the TFT
array glass substrate and a color-filter glass substrate.
Color (Red, Green, Blue) data signals from a host system (e.g. PC, signal generator, etc.) are modulated
into best form for active matrix system by a signal processing board, and sent to the driver LSIs which
drive the individual TFT arrays.
The TFT array as an electro-optical switch regulates the amount of transmitted light from the backlight
assembly, when it is controlled by data signals. Color images are created by regulating the amount of
transmitted light through the TFT array of red, green and blue dots.

Note1: The power supply voltage cycle between lamps should be kept on a same phase. "VS" and
"VBLH" are the voltage value between low voltage side (Cold) and high voltage side (Hot).
Note2: The asymmetric ratio of working waveform for lamps (Power supply voltage peak ratio,
power supply current peak ratio and waveform space ratio) should be less than 5 % (See the
following figure.). If the waveform is asymmetric, DC (Direct current) element apply into
the lamp. In this case, a lamp lifetime may be shortened, because a distribution of a lamp
enclosure substance inclines toward one side between low voltage terminal (Cold terminal)
and high voltage terminal (Hot terminal).
Pa: Supply voltage/current peak for positive, Pb: Supply voltage/current peak for negative
Sa: Waveform space for positive part, Sb: Waveform space for negative part
Note3: The lamp holder of this product contains two backlight lamps. The low voltage terminal of
both lamps is connected to one contact point. Also above power supply current specification
is one lamp duty. Therefore, this lamp holder becomes twice as many power supply current
as above value on low voltage (Cold) line. The measurement for the power supply current
value of one lamp should measure on high voltage (Hot) line to each lamp.
Note4: In case "FO" is not the recommended value, beat noise may display on the screen, because
of interference between "FO" and "1/th". Recommended value of "FO" is as following.

6. PRECAUTIONS
6.1 MEANING OF CAUTION SIGNS
The following caution signs have very important meaning. Be sure to read "6.2 CAUTIONS", after
understanding this contents!
This sign has the meaning that customer will be injured by himself, if customer has
wrong operations.
6.2 CAUTIONS
Pay attention to burn injury for the working backlight! It may be over 35°
°°
°C from
ambient temperature.
Do not shock and press the LCD panel and the backlight! Danger of breaking, because
they are made of glass. (Shock: To be not greater 539m/s2 and to be not greater 11ms,
Pressure: To be not greater 19.6N)
6.3 ATTENTIONS
6.3.1 Handling of the product
Take hold of both ends without touch the circuit board when customer pulls out products (LCD
modules) from inner packing box. If customer touches it, products may be broken down or out of
adjustment, because of stress to mounting parts.
Do not hook cables nor pull connection cables such as flexible cable and so on, for fear of damage.
If customer puts down the product temporarily, the product puts on flat subsoil as a display side
turns down.
Take the measures of electrostatic discharge such as earth band, ionic shower and so on, when
customer deals with the product, because products may be damaged by electrostatic.
The torque for mounting screws must never exceed 0.29Nm. Higher torque values might result in
distortion of the bezel.
Do not press or rub on the sensitive display surface. If customer clean on the panel surface, NEC
Corporation recommends using the cloth with ethanolic liquid such as screen cleaner for LCD.
Do not push-pull the interface connectors while the product is working, because wrong power
sequence may break down the product.
6.3.2 Environment
Do not operate or store in high temperature, high humidity, dewdrop atmosphere or corrosive
gases. Keep the product in antistatic pouch in room temperature, because of avoidance for dusts
and sunlight, if customer stores the product.
Do not operate in high magnetic field. Circuit boards may be broken down by it.
Use an original protection sheet on the product surface (polarizer). Adhesive type protection sheet
should be avoided, because it may change color or properties of the polarizer.
NL10276BC20-04
DATA SHEET EN0555EJ4V1DS00 23
6.3.3 Characteristics
The following items are neither defects nor failures.
Response time, luminance and color may be changed by ambient temperature.
The LCD may be seemed luminance non-uniformity, flicker, vertical seam 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.
Do not display the fixed pattern for a long time because it may cause image sticking. Use a screen
saver, if the fixed pattern is displayed on the screen.
The display color may be changed by viewing angle because of the use of condenser sheet in the
backlight unit.
Optical characteristics may be changed by input signal timings.
The interference noise of input signal frequency for this product's signal processing board and
luminance control frequency of customer's backlight inverter may appear on a display. Set up
luminance control frequency of backlight inverter so that the interference noise does not appear.
6.3.4 Other
All GND, backlight inverter ground (GNDB), VCC and backlight inverter power supply voltage
(VDDB) terminals should be used without a non-connected line.
Do not disassemble a product or adjust volume without permission of NEC Corporation.
See "REPLACEMENT MANUAL FOR LAMPHOLDER", if customer would like to replace
backlight lamps.
Pay attention not to insert waste materials inside of products, if customer uses screwnails.
