it’s reported that Sony has an entire wall of its 11-inch XEL-1 OLED TVs set up here at Ceatec 2008, but in contrast with past gadget shows, it's not the only company showing off OLED prototypes. Panasonic may have said earlier this week that OLED is still far from becoming a mass-produced mainstream technology for use in big-screen TVs, but other electronics makers are plowing ahead with their own research on the organic, thin film technology: NEC, Sony, and KDDI showed off what they've been doing with OLED in their research labs.
