A Brighter Outlook For Handheld Screens
http://news.com.com/2100-1041_3-5086040.html?tag=nefd_top
"A Japanese company has developed lighting technology that it claims makes handheld screens brighter and clearer, with reduced power consumption. Omron, of Kyoto, Japan, has announced that its research labs produced a technique--dubbed hybrid-integration technology--that uses very small, or "nano," prism arrays to achieve a threefold improvement in contrast ratio compared to conventional front-lighting methods. The tiny prism array prevents reflection of unnecessary light and produces clear screen images."

Anything brighter and cheaper is good.
Just curious, what happened to OLED ? It is brighter, it is way cheaper .. but how come it is not on the consumer market yet ? There is only one model of Kodak camera is using it, nothing else. Conspiracy among LCD makers ?

My understanding with OLED is that the technology is so different that it is too expensive to retool a FAB to make the displays, so they are done on a small scale right now, and it will become more available as completely new FABs are built. Also, I think the outside viewability is not as good as transflective. Power consumption and inside viewing are unbeatable however. Sadly, the outside viewability is a major consideration for PDA screens as they are typically used with the screen pointing upward to the sky, or at least some point above the horizon. A camera, on the other hand, is more likely to be vertical, reflecting some low level reflection below the horizon.
