INTRODUCTION
NEC products are classified into the following three quality grades:
"Standard","Special","Specific"
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
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
Monochrome LCD module NL256204AM15-01 and NL256204AM15-01A 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.
Grayscale 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. Monochrome images are created by regulating the
amount of transmitted light through the TFT array.

*2: LVDS signals should be measured at the terminal of 100: resistance.
Note1: In terms of voltage variation (voltage drop) while VDD rising edge is below 10.8V, a protection
circuit may work, and then this product may not work.
Note2: VDD should be 10.8V or more during VDD ON period.
Note3: LVDS signals and CSR, CSL, SCLK, SDAT must be Low or High-impedance, exclude the
VALID period (See above sequence diagram), in order to avoid that internal circuits is
damaged.
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 customer stops the display and function signals, they should be
cut VDD.
Note4: At the beginning of the serial communication mode, take 20ms or more after the LVDS signal
input.

Note1: The inverter power supply voltage (VDDB) should be inputted within the valid period of LVDS
signals, in order to avoid unstable data display.
Note2: If tr is more than 800ms, the backlight will be turned off by a protection circuit for inverter.
Note3: When VDDB is 0V or BRTC is Low, PWSEL must be set to Low or Open.
