The EDEX2004 show is apparently an exhibition all about electronic displays. It's currently being held at Tokyo's Big Site, wherever that may be.
Anyway, this is just a list of what different companies had to exhibit for the first day of the show. For pictures and more details, you'll need to see the original Japanese article. As always, if you would like me to translate more of the content, just contact me and I'd be glad to help you. I particularly like the 2.6" screen with VGA resolution.

The "EDEX2004 Electronic Display Exhibition" is going o­n from the 7th to 9th at Tokyo's Big Site. The exhibition is targeted at electronic display specialists, and is held jointly with the "SEMI FPD Expo 2004" that focuses o­n the material and production of electronic displays.
