1. OUTLINE
1.1 STRUCTURE AND PRINCIPLE
Color LCD module NL10276BC30-17 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.
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.

Note4
Note1: This product consists of 4 backlight lamps, and these specifications are for each lamp.
Note2: The lamp 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).
Note3: The asymmetric ratio of working waveform for lamps (Lamp voltage peak ratio, Lamp 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).
When designing the backlight inverter, evaluate asymmetric of lamp working waveform
sufficiently.

"0" voltage, exclude the VALID period (See above sequence diagram). If these signals are
higher than 0.3V, the internal circuit 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.
Note3: VCC should be 3.0V or more while VCC ON period.
Note4: The backlight power supply voltage should be inputted within the valid period of display

6. PRECAUTIONS
6.1 MEANING OF CAUTION SIGNS
The following caution signs have very important meaning. Be sure to read "6.2 CAUTIONS"
and "6.3 ATTENTIONS", after understanding these contents!
!
This sign has the meaning that customer will be injured by himself or the product will
sustain a damage, if customer has wrong operations.
This sign has the meaning that customer will get an electrical shock, if customer has
wrong operations.
This sign has the meaning that customer will be injured by himself, if customer has
wrong operations.
6.2 CAUTIONS
∗ Do not touch the working backlight. Customer will be in danger of an electric shock.
∗ Do not touch the working backlight. Customer will be in danger of burn injury.
∗ Do not shock and press the LCD panel and the backlight! There is a danger of
breaking, because they are made of glass. (Shock: To be not greater TBD m/s2 and to
be not greater TBD ms, Pressure: To be not greater TBD N)
6.3 ATTENTIONS
!
6.3.1 Handling of the product
① Take hold of both ends without touch the circuit board cover 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.
② Do not hook cables nor pull connection cables such as lamp cable and so on, for fear of damage.
③ If customer puts down the product temporarily, the product puts on flat subsoil as a display side turns
down.
④ 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.
⑤ The torque for mounting screws must never exceed TBD N⋅m. Higher torque values might result in
distortion of the bezel.
⑥ The product must be installed using mounting holes without undue stress such as bends or twist (See
outline drawings). And do not add undue stress to any portion (such as bezel flat area) except
mounting hole portion.
Bends or twist described above and undue stress to any portion except mounting hole portion may
cause display un-uniformity.
⑦ Do not press or rub on the sensitive display surface. If customer clean on the panel surface, NEC
recommends using the cloth with ethanolic liquid such as screen cleaner for LCD.
PRELIMINARY DATA SHEET DOD-PD-0568 (1st edition)
24
NL10276BC30-17
⑧ Do not push-pull the interface connectors while the product is working, because wrong power
sequence may break down the product.
⑨ Do not bend or unbend the lamp cable at the near part of the lamp holding rubber, to avoid the
damage for high voltage side of the lamp. This damage may cause a lamp breaking and abnormal
operation of high voltage circuit.
⑩ When installing the lamp cable, do not attach the lamp cable on the metal part of the LCD module
directly. This may cause leakage high frequency current to the metal part, then the brightness may
decrease or the lamp may not light.
⑪ When not connecting FG of the LCD module to the customer's equipment ground, inverter noise
may create a beat frequency that will cause video noise on the LCD screen.
⑫ When customer deals with the product, use of an original protection sheet on the product surface
(polarizer) is recommended for protection of panel surface. Adhesive type protection sheet may
change color or properties of the polarizer.
6.3.2 Environment
① 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.
② In order to prevent dew condensation occurring by temperature difference, the product packing box
must be opened after leave under the environment of an unpacking room temperature enough.
Because a situation of dew condensation occurring is changed by the environmental temperature and
humidity, evaluate the leaving time sufficiently. (Recommendation leaving time: 6 hour or more with
packing state)
③ Do not operate in high magnetic field. Circuit boards may be broken down by it.
④ This product is not designed as radiation hardened.
6.3.3 Characteristics
The following items are neither defects nor failures.
① Response time, luminance and color may be changed by ambient temperature.
② The LCD may be seemed luminance non-uniformity, flicker, vertical seam or small spot by display
patterns.
③ 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.
④ 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.
⑤ The display color may be changed by viewing angle because of the use of condenser sheet in the
backlight.
⑥ Optical characteristics may be changed by input signal timings.
⑦ 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
① All GND and VCC terminals should be used without any non-connected lines.
② Do not disassemble a product or adjust variable resistors without permission of NEC.
③ See "REPLACEMENT MANUAL FOR LAMP HOLDER SET", if customer would like to replace
backlight lamps.
④ Pay attention not to insert waste materials inside of products, if customer uses screwnails.
⑤ Pack the product with original shipping package, because of avoidance of some damages during
transportation, when customer returns it to NEC for repair and so on.
⑥ The LCD module by itself or integrated into end product should be packed and transported with
display in the vertically position. Otherwise the display characteristics may be impaired.
