Default Sumitomo - we won't be able to make OLED TVs in 2009, sorry!

An informed source at Cambridge Display Technology, the company that develops the polymer light emitting materials (P-OLEDs) to be used in the forthcoming TVs, says “Sumitomo is working with partners so the timing of any product launch is not just [its] call.” The source goes on to say Sumitomo President Hiromasa Yonekura was “misquoted” in his speech regarding the development of OLED TVs and the timescale placed upon their release. . .

You will probably have heard of the OLED (which stands for Organic Light Emitting Diode) already, but you probably don’t know two rival technologies exist within it. Small Molecule OLEDs (SMOLEDs) are the most widely used version, already employed by companies such as Samsung in a few of their mobile phones. These are created by heating up the organic matter and evaporating it onto a template, thus creating a display. This is a complex process and can sometimes be only 5% efficient, as a lot of materials are lost in the evaporation process. P-OLEDs, also knows as PLEDs or Light Emitting Polymers, can be directly printed into a TV design using an inkjet printer, thus making them a lot more efficient. However, PLED displays have not been able to perform as well as SMOLEDs in the past, and were less cost-effective.
