INTRODUCTION
The products are classified into three quality grades: "Standard", "Special", and "Specific" of the
highest grade of a quality assurance program at the choice of a customer. Each quality grade is designed
for applications described below. Any customer who intends to use a product for application other than
that of Standard quality grade is required to contact an NEC sales representative in advance.
The Standard quality grade applies to the products developed, designed and manufactured in
accordance with the NEC standard quality assurance program, which are designed for such application as
any failure or malfunction of the products (sets) or parts/components incorporated therein a customer uses
are, directly or indirectly, free of any damage to death, human bodily injury or other property, like general
electronic devices.
Examples: Computers, office automation equipment, communications equipment, test and measurement
equipment, audio and visual equipment, home electronic appliances, machine tools, personal
electronic equipment, industrial robots, etc.
The Special quality grade applies to the products developed, designed and manufactured in accordance
with an NEC quality assurance program stricter than the standard one, which are designed for such
application as any failure or malfunction of the products (sets) or parts/components incorporated therein a
customer uses might directly cause any damage to death, human bodily injury or other property, or such
application under more severe condition than that defined in the Standard quality grade without such
direct damage.
Examples: Control systems for transportation equipment (automobiles, trains, ships, etc.), traffic control
systems, anti-disaster systems, anti-crime systems, medical equipment not specifically
designed for life support, safety equipment, etc.
The Specific quality grade applies to the products developed, designed and manufactured in accordance
with the standards or quality assurance program designated by a customer who requires an extremely
higher level of reliability and quality for such products.
Examples: Military systems, aircraft control equipment, aerospace equipment, nuclear reactor control
systems, medical equipment/devices/systems for life support, etc.
The quality grade of this product is the "Standard" unless otherwise specified in this document.

1. OUTLINE
1.1 STRUCTURE AND PRINCIPLE
Monochrome LCD module NL256204AM15-04A 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 monochrome-filter glass substrate.
Grayscale 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. Monochrome images are created by regulating the
amount of transmitted light through the TFT array.

Note1: Luminance control frequency indicate the input pulse frequency, when select the external pulse

Note2: The power supply lines (VDDB and GNDB) have large ripple voltage (See "4.3.4 Power
supply voltage ripple".) during luminance control. There is the possibility that the ripple
voltage produces acoustic noise and signal wave noise in audio circuit and so on. Put a
capacitor (5,000 to 6,000PF) between the power supply lines (VDDB and GNDB) to reduce the
noise, if the noise occurred in the circuit.

Note1: If there is a voltage variation (voltage drop) at the rising edge of VDD below 10.8V, there is a
possibility that a product does not work due to a protection circuit.
Note2: LVDS signals and CSR, CSL, SCLK, SDAT must be set to Low or High-impedance, except the
VALID period (See above sequence diagram), in order to avoid the circuitry damage .
If some of signals are cut while this product is working, even if the signal input to it once again,
it might not work normally. If a customer stops the display and function signals, VDD also must
be shut down.
