1. OUTLINE
1.1 STRUCTURE AND PRINCIPLE
Color LCD module NL204153AC21-17 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 data signals from a host system (e.g. 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.

4.6 LUMINANCE CONTROL
4.6.1 Luminance control methods
Method Adjustment and luminance ratio
x Adjustment
The variable resistor (R) for luminance control should be 10k:
r5%, 1/10W. Minimum point of the resistance is the minimum
luminance and maximum point of the resistance is the maximum
luminance.

Note4
Note1: In case of the variable resistor control method and the voltage control method, noises may appear
on the display image depending on the input signals timing for LCD panel signal processing
board.
Use PWM method, if interference noises appear on the display image!
Note2: The LED driver board will stop working, if the Low period of BRTP signal is more than 50ms
while BRTC signal is High or Open. Then the backlight will not turn on anymore, even if BRTP
signal is input again. This is not out of order. The LED driver board will start to work when power
is supplied again.
Note3: These data are the target values.
Note4: See "4.6.2 Detail of BRTP timing".
The resistor (R) must be connected between BRTH-BRTI terminals.
x Luminance ratio Note3
x Adjustment
Voltage control method works, when BRTH terminal is 0V and VBI
voltage is input between BRTI-BRTH terminals. This control
method can carry out continuation adjustment of luminance.
Luminance is the maximum when BRTI terminal is Open.
x Luminance ratio Note3
x Adjustment
Pulse width modulation (PWM) method works, when PWSEL
terminal is Low and PWM signal (BRTP signal) is input into BRTP
terminal. The luminance is controlled by duty ratio of BRTP signal.

Response time is measured at the time when the luminance changes from "black" to "white", or
"white" to "black" on the same screen point, by photo-detector. Ton is the time when the luminance
changes from 10% up to 90%. Also Toff is the time when the luminance changes from 90% down to

Note2: Estimated luminance lifetime is not the value for LCD module but the value for LED
elementary substance.
Note3: By ambient temperature, the lifetime changes particularly. Especially, in case the product
works under high temperature environment, the lifetime becomes short.

7. PRECAUTIONS
7.1 MEANING OF CAUTION SIGNS
The following caution signs have very important meaning. Be sure to read "7.2 CAUTIONS" and
"7.3 ATTENTIONS"!
This sign has the meaning that a customer will be injured or the product will sustain
!
7.2 CAUTIONS
damage if the customer practices wrong operations.
This sign has the meaning that a customer will be injured if the customer practices
wrong operations.

NL204153AC21-17
Do not shock and press the LCD panel and the backlight! There is a danger of breaking,
because they are made of glass. (Shock: Equal to or no greater than 294m/s
or no greater than 11ms, Pressure: Equal to or no greater than 19.6N (
7.3 ATTENTIONS
7.3.1 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 or 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 0.735Nm. Higher torque might result in
distortion of the bezel. And the length of product mounting screws must be d 5.0mm.

ཱུ 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.
Recommended installing method: Ideal plane "A" is defined by one mounting hole (datum point)
and other mounting holes. The ideal plane "A" should be the same plane within r0.3 mm.
ྲྀ Do not press or rub on the sensitive product surface. When cleaning the product surface, wipe it with
a soft dry cloth.
ཷ Do not push or pull the interface connectors while the product is working.
ླྀ 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 by any chance,
please wash it away with soap and water.
7.3.2 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 occurred by temperature difference, the product packing box
must be opened after enough time being left under the environment of an unpacking room. Evaluate
the storage time sufficiently because dew condensation is affected by the environmental temperature
and humidity. (Recommended leaving time: 6 hours or more with the original packing state after a
customer receives the package)
ི Do not operate in high magnetic field. If not, circuit boards may be broken.
ཱི This product is not designed as radiation hardened.

7.3.3 Characteristics
The following items are neither defects nor failures.
Response time, luminance and color may be changed by ambient temperature.
ཱ Display mura, flickering, vertical streams or tiny spots may be observed depending on display
patterns.
ི 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.
7.3.4 Others
All GND, GNDB, VDD and VDDB terminals should be used without any non-connected lines.
ཱ Do not disassemble a product or adjust variable resistors.
ི Pack the product with the original shipping package, in order to avoid any damages during
transportation, when returning the product to NLT for repairing and so on.
ཱི The LCD module by itself or integrated into end product should be packed and transported with
display in the vertical position. Otherwise the display characteristics may be degraded.
