1. OUTLINE
1.1 STRUCTURE AND PRINCIPLE
Color LCD module NL6448BC33-64E 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 indi vidual 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: This product consists of 2 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 (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.
Pa: Supply voltage/current peak for positive, Pb: Supply voltage/current peak for negative
Sa: Wa veform space for positive part, Sb: Waveform space for negative part.
Note4: This product consists of 2 lamps. 2 lamps are contained in the 1 lamp holder, and both lamps
are connected to 1 low voltage cable. Recommended lamp current is 5.0mArms typical for
each lamp, and sum of 2 lamps is 10mArms typical. The lamp current should be measured by
high-frequency current meter at the low voltage terminal.
Note5: The inverter should be designed so that the lamp starting voltage can be maintained for more
than 1 second. Otherwise the lamp may not be turned on.
Note6: 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.
th: Horizontal cycle (See "4.9.2 Timing characteristics".)
n : Natural number (1, 2, 3 ⋅⋅⋅⋅⋅⋅⋅⋅)
Note7: Method of lamp cable installation may invite fluctuation of lamp current and voltage or
asymmetric of lamp working waveform. When designing method of lamp cable installation,
evaluate the fluctuation of lamp current, voltage and working waveform sufficiently.

Note8: In case of Inverter with Ballast condenser, "VS" is the voltage lebel between Ballast condenser
and Connector (Refer to the below “Example of measurement”). "VS" should be designed to
be more than minimum "VS". Otherwise the lamp may not be turned on because the lamp
starting voltage is less than minimum "VS".

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. 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/s2 and to be not greater
11 ms, Pressure: To be not greater 19.6 N (φ16mm jig))
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 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.
NL6448BC33-64E
DATA SHEET DOD-PP-0163 (1st edition) 27
Properly connect the plug (backlight side) to adaptable socket (inverter side) without incomplete
connection. After connecting, be careful not to hook the lamp cables because incomplete connection
may occur by hooking the lamp cables. This incomplete connection may cause abnormal operation
of high voltage circuit.
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 not connecting FG of the LCD module to the customer's equipment ground, inverter noise
may create video noise on the LCD screen.
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.
Usually liquid crystals don't leak through the breakage of glasses because of the surface tension of
thin layer and the construction of LCD panel. But, if you contact with liquid crystal for the worst,
please wash it out with soap.
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.
6.3.3 Characteristics
The following items are neither defects nor failures.
Response time, luminance and color may be changed by ambient 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.
After the product is stored under condition of low temperature or dark place for a long time, the cold
cathode fluorescent lamp may not be turned on under the same condition because of the general
characteristic of cold cathode fluorescent lamp. In addition, when Luminance control ratio is low in
pulse width modulation method inverter, the lamp may not be turned on. In this case, power should
be supplied again.
