product for application other than that of Standard is required to contact an NLT sales representative in
advance.
The Standard: Applications as any failure, malfunction or error of the products are free from any damage
to death, human bodily injury or other property (Products Safety Issue) and not related the safety of the
public (Social Issues), like general electric devices.
Examples: Office equipment, audio and visual equipment, communication equipment, test and
measurement equipment, personal electronic equipment, home electronic appliances, car
navigation system (with no vehicle control functions), seat entertainment monitor for vehicles
and airplanes, fish finder (except marine radar integrated type), PDA, etc.
The Special: Applications as any failure, malfunction or error of the products might directly cause any
damage to death, human bodily injury or other property (Products Safety Issue) and the safety of the public
(Social Issues) and required high level reliability by conventional wisdom.
Examples: Vehicle/train/ship control system, traffic signals system, traffic information control system, air
traffic control system, surgery/operation equipment monitor, disaster/crime prevention system,
etc.
The Specific: Applications as any failure, malfunction or error of the products might severe cause any
damage to death, human bodily injury or other property (Products Safety Issue) and the safety of the public
(Social Issues) and developed, designed and manufactured in accordance with the standards or quality
assurance program designated by the customer who requires extremely high level reliability and quality.

1. OUTLINE
1.1 STRUCTURE AND PRINCIPLE
Color LCD module NLB121SV01L-01 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 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 APPLICATION

Note1: When designing of the power supply, take the measures for the prevention of surge voltage.
Note2: This value excludes peak current such as overshoot current.
Note3: The power sup pl y lines (VDD an d GND) may hav e ripple vo ltag e during lu minan ce co ntrol of
LED. There is the possibility that the ripple voltage produces acoustic noise and signal wave
noise in audio circuit and so on. Put a capacitor between the power supply lines (VDD and
GND) to reduce the noise if necessary.
Note4: A recommended f
Note5: Depending on the frequency used, so noise may appear on the screen, please conduct a
thorough evaluation.

a possibility that a product does not work due to a protection circuit.
Note2: Display signals (D0+/-, D1+/-, D2+/-, D3+/- and CLK+/-) and function signals (DPS and
