A Japanese consortium of 13 companies (including Sharp and Hitachi) claims that they found a way to make LCDs using plastic film instead of a glass substrate. This means that those displays can be very thin and flexible. They do admit however that this is a very complicated process. They have shown a 3.5" bendable color LCD that just 0.49mm thick and weights 7 grams. They hope to make a better display by 2012, and use this technology to mass produce thin, curved LCD displays.
The companies say that the new manufacturing process is simpler than the one used in current LCDs, and also the new displays will consumer 70% less energy!
