While NEC Corporation has been making continuous effort to enhance the reliability of its products, the
possibility of failures cannot be eliminated entirely. To minimize risks of damage to property or injury to
person arising from a failure in an NEC product, customers must incorporate sufficient safety measures
in their design, such as redundancy, fire-containment and anti-failure features.
NEC products are classified into the following three quality grades:
"Standard", "Special", "Specific"
The "Specific" quality grade applies only to applications developed based on a customer designated
"quality assurance program" for a specific application. The recommended applications of a product
depend on its quality grade, as indicated below. Customers must check the quality grade of each
application 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: Military systems, aircraft, aerospace equipment, submersible repeaters, nuclear reactor control
systems, life support systems (medical equipment, etc.) and any other equipment
The quality grade of this product is "Standard" unless otherwise specified in this document. If
customers intend to use this product for applications other than those specified for "Standard" quality
grade, they should contact NEC Corporation sales representative in advance.

1. OUTLINE
1.1 STRUCTURE AND PRINCIPLE
NL3224BC35-20 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: 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.

4.4 POWER SUPPLY VOLTAGE SEQUENCE
4.4.1 Sequence for LCD panel signal processing board
Note1: In terms of voltage variation (voltage drop) while VCC rising edge is below 3.0V in
"VCC = 3.3V" or 4.75V in "VCC = 5.0V", a protection circuit may work, and then this
product may not work.
Note2: Display (CLK, Hsync, Vsync, DE, R0 to R5, G0 to G5, B0 to B5) and function (DPSH,
DPSV, PNS) signals must be Low or High-impedance, exclude the VALID period (See
above sequence diagram), in order to avoid that internal circuits is damaged.
If some of display and function signals of this product are cut while this product is
working, even if the signal input to it once again, it might not work normally. If customer
stops the display and function signals, they should be cut VCC.
4.4.2 Sequence for backlight inverter (Option)
Note1: These are display and function signals for LCD panel signal processing board.
Note2: The backlight inverter voltage (VDDB) should be inputted within the valid period of
display and function signals, in order to avoid unstable data display.

The luminance is measured at near the 5 points shown below.
4.10.4 Definition of response times
Response time is measured, the luminance changes from "white" to "black", or "black" to "white" on
the same screen point, by photo-detector. Ton is the time it takes the luminance change from 90%
down to 10%. Also Toff is the time it takes the luminance change from 10% up to 90% (See the

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 980m/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.
NL3224BC35-20
DATA SHEET EN0556EJ3V0DS00 29
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.
