| JEIDA Sets Standards on Display, Info Appliance Interfaces
February 26, 1999 (TOKYO) -- The Japan Electronic Industry Development
Association set interface standards to connect display devices such
as LCD monitors with information appliances.
|The new standards are called "Digital Interface Standards for Monitor
In connecting flat panel displays such as liquid-crystal display (LCDs)
with digital appliances such as personal computers, digital interfaces
are better than analog now in wide use in CRT displays in terms of image
quality and cost. But there have so far been no standard specifications
on digital interfaces for displays.
The Digital Interface Standardization Committee, a voluntary group of
Japan's electronic business industry, started to study standards in
August 1997. JEIDA's Digital Interface Standards for Monitor Working
Group proceeded to draw up work in cooperation with overseas enterprises
and standards groups since June 1998.
The interfaces are to connect IT devices such as PCs, workstations and
various kinds of devices for industrial use with display devices, and
interfaces among display devices. The standards define signal standards,
electric characters, connectors, pin layouts and software. They adopt
three digital transmission methods: TMDS, LVDS/LDI and GVIF.
The full text of the standards is at JEIDA's
home page in Japanese.
