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.

1.2 APPLICATIONS

• For industrial use

1.3 FEATURES

• Ultra-wide viewing angle (Adoption of Super Advanced -Super Fine TFT (SA-SFT))

• LVDS interface (8-bit)

• Selectable LVDS input map

• Wide color gamut

• High contrast

• Small foot print

• Edge light type backlight (without inverter)

• Replaceable lamp for backlight

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.

Note1: In terms of voltage variation (voltage drop) while VCC rising edge is below 3.0V, a

protection circuit may work, and then this product may not work.

Note2: Display signals (D0+/-, D1+/-, D2+/-, D3+/- and CK+/-) and function signal (MSL) must be

"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

and function signals, in order to avoid unstable data 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/s²and 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.
