On May 9, 2008, Sumitomo Chemical announced its plans to produce and sell 40″ and larger organic electroluminescence display panels. I am assuming in this case that organic electroluminescence (organic EL) means the same thing as organic light emitting diode (OLED). JCNetwork’s article point to EL panels being thinner than LCDs and consuming less power. I must disagree.
Everyone seems to think Sony’s XEL-1 OLED TV is super thin and much thinner than a comparable LCD. Well, the upper part of the XEL-1 is in fact much thinner. The lower part? I’m not sure; it looks pretty think to me. and the base? Well, if you had to put that base on the back of the display, we’re looking at a downright chunky 11″ OLED TV. The part about consuming less power: yes, OLED displays consume less power when they are black. And that’s why you see a lot of OLED-based mobile phones and PMPs with UIs that are mostly black. Will a 40″ OLED TV consume less power than a 40″ LCD TV? Depends on whether you’re watching The Matrix or Ice Age.
Sumitomo Chemical is developing a “macromolecule-type” organic EL panel because these have a cost and scalability advantage in manufacturing due to ink-jet printing processes. Ink-jet based manufacturing of OLEDs have been in R&D for many years. I hope 2009 is the year for Sumitomo, but as is the case with all new technologies, including OLEDs, things generally take a bit longer to get things up and running smoothly.
