INTRODUCTION
The "Specific" quality grade applies only to applications developed based on a customer designated
"quality assurance program" for a specific application. The recommended applications of a product
depend on its quality grade, as indicated below. Customers must check the quality grade of each
application before using it in a particular application.
Standard: Computers, office equipment, communications equipment, test and measurement equipment,
audio and visual equipment, home electronic appliances, machine tools, personal electronic
equipment and industrial robots
Special: Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster
systems, anti-crime systems, safety equipment and medical equipment (not specifically
designed for life support)
Specific: Military systems, aircraft, aerospace equipment, submersible repeaters, nuclear reactor control
systems, life support systems (medical equipment, etc.) and any other equipment
The quality grade of this product is "Standard" unless otherwise specified in this document. If
customers intend to use this product for applications other than those specified for "Standard" quality
grade, they should contact NEC sales representative in advance.

1. OUTLINE
1.1 STRUCTURE AND PRINCIPLE
Color LCD module NL128102BC29-01B and NL128102BC29-01C are 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 monochrome-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.

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.

evaluate the fluctuation of lamp current, voltage and working waveform sufficiently.
