Sony recently pushed out their new product: OLED (Organic Light Emitting Display) TV XEL-1 (11 inch) which is only 3 millimeters thick! The marketing price is around $1700 which is in the same price range of a Sony 40 inch LCD. This is still too early to compare OLED vs LCD due to the high cost of this new technology. However, OLED is far more efficient in electricity consumption than traditional LCD. It's funny to say "traditional LCD" while many of our university labs are still using CRT monitors... In short, OLED is a thinner, more efficient in power, better graphics screen display technology than LCD. I have heard OLED has very obvious improvement on motion graphics with high frame sets (graphics with high speed motion) over LCD.

What's OLED's weakness? Low life expectancy. The current OLED technology is only going to last half as long as the LCDs. But it still should provide you 30000 hours of viewing. Another problem with OLED TV is Sony is only roducing 2000 per month world wide at the moment. They say they are losing money on selling every single OLED TV.

Me and a couple of my colleagues were talking about the best display devices out there. I was just describing my dream set, 5 LCDs all around me, spread out from one base, all connected, can be used for both PC and Mac... Then I found this one on the web:

This is a real display set, created by Liebermann, highest resolution reaches 19200 X 2400. Only 2.5 inch thick. 16.7 million color.

How big is big? I know I have always wanted a bigger display, my PC monitor went from 14" to 15" to 17" then to 19"; My home TV went from 21" to 32" to 52". But whenever I see a large screen being displayed in the stores, there is still an urge to make a move. So, I don’t know the answer to the question, but I do know I would not mind to have a wall sized display to replace my window like in the science fiction movies in 10 years. Sony and Samsung both made some some ice breaking development in large sized display technologies recently. Sony has just show cased the largest display in the world, the 50m x 10m video projection. It is using Grating Light Valve to transform RGB values to a 78m x 16m screen 60 meters away.

Samsung responded (with Sony’s help) with the largest LCD – 82”（1870mm×2200mm). This is the 7th generation of glass panels (S-PVA) from “S-LCD” (a joint company between Samsung and Sony). It’s time to start saving for my “wall display”.
