1. OUTLINE
1.1 STRUCTURE AND PRINCIPLE
Color LCD module NL8060BC31-42 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. signal generator, etc.) are modulated into best form for active matrix system by a signal processing circuit, 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.

Note3: 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). When designing the inverter, evaluate asymmetric of lamp working waveform sufficiently.

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.
www.panelook.com
NL8060BC31-42/42D
6.2 CAUTIONS
Do not touch the working backlight. There is a danger of an electric shock.
Do not touch the working backlight. There is a 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 539m/s 11ms, Pressure: To be not greater 19.6 N (
6.3 ATTENTIONS
6.3.1 Handling of the product
཰ Take hold of both ends without touching the circuit board when the product (LCD module) is picked
up from inner packing box to avoid broken down or misadjustment, because of stress to mounting parts on the circuit board.
ཱ Do not hook nor pull cables such as lamp cable, and so on, in order to avoid any damage. ི When the product is put on the table temporarily, display surface must be placed downward. ཱི When handling the product, take the measures of electrostatic discharge with such as earth band,
ionic shower and so on, because the product may be damaged by electrostatic.
ུ The torque for product mounting screws must never exceed 0.294Nm. Higher torque might result in
distortion of the bezel.
ཱུ 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). Bends or twist described above and undue stress to any portion except mounting hole portion may cause display mura.
ྲྀ Do not press or rub on the sensitive product surface. When cleaning the product surface, use of the
cloth with ethanolic liquid such as screen cleaner for LCD is recommended.
ཷ Do not push nor pull the interface connectors while the product is working. ླྀ 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.
ཹ If the lamp cable is attached on the metal part of the product directly, high frequency leak current to
the metal part may occur, then the brightness may decrease or the lamp may not be turned on.

ེ When handling the product, use of an original protection sheet on the product surface (polarizer) is
recommended for protection of product surface. Adhesive type protection sheet may change color or characteristics of the polarizer.
6.3.2 Environment
཰ Do not operate or store in high temperature, high humidity, dewdrop atmosphere or corrosive gases.
Keep the product in packing box with antistatic pouch in room temperature to avoid dusts and sunlight, when storing the product.
ཱ In order to prevent dew condensation occurring by temperature difference, the product packing box
should be opened after enough time being left under the environment of an unpacking room. Evaluate the leaving time sufficiently because a situation of dew condensation occurring is changed by the environmental temperature and humidity. (Recommended leaving time: 6 hours or more with packing state)
ི Do not operate in high magnetic field. Circuit boards may be broken down by it. ཱི This product is not designed as radiation hardened.
www.panelook.com
NL8060BC31-42/42D
6.3.3 Characteristics
The following items are neither defects nor failures.
཰ Characteristics of the LCD (such as response time, luminance, color uniformity and so on) may be
changed depending on ambient temperature. If the product is stored under condition of low temperature for a long time, it may cause display mura. In this case, the product should be operated after enough time being left under condition of operating temperature.
ཱ Display mura, flicker, vertical seam or small spot may be observed depending on 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 depending on viewing angle because of the use of condenser
sheet in the backlight.
ཱུ Optical characteristics may be changed depending on input signal timings. ྲྀ The interference noise between input signal frequency for this product's signal processing board and
luminance control frequency of the inverter may appear on a display. Set up luminance control frequency of the inverter so that the interference noise does not appear.
6.3.4 Other
཰ All GND and VCC terminals should be used without any non-connected lines. ཱ Do not disassemble a product or adjust variable resistors. ི See "REPLACEMENT MANUAL FOR LAMP HOLDER SET", when replacing backlight lamps. ཱི Pay attention not to insert foreign materials inside of the product, when using tapping screws. ུ Pack the product with original shipping package, in order to avoid any damages during
transportation, when returning the product to NEC for repair and so on.
