INTRODUCTION 

 

The Copyright to this document belongs to NEC LCD Technologies, Ltd. (hereinafter called "NEC"). 

No part of this document will be used, reproduced or copied without prior written consent of NEC. 

 

NEC does and will not assume any liability for infringement of patents, copyrights or other intellectual 

property rights of any third party arising out of or in connection with application of the products 
described herein except for that directly attributable to mechanisms and workmanship thereof. No license, 
express or implied, is granted under any patent, copyright or other intellectual property right of NEC. 

 

Some electronic parts/components would fail or malfunction at a certain rate. In spite of every effort to 

enhance reliability of products by NEC, the possibility of failures and malfunction might not be avoided 
entirely. To prevent the risks of damage to death, human bodily injury or other property arising out 
thereof or in connection therewith, each customer is required to take sufficient measures in its safety 
designs and plans including, but not limited to, redundant system, fire-containment and anti-failure. 

 
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.
