Finally a bit of competition to pep up the transparent OLED market. Samsung and LG seem to have had this party all to themselves until now, but TDK is stepping in with a 2-inch passive matrix screen and a humble QVGA (320 x 240) resolution. Sure, those aren't groundbreaking specs, but a claimed 50 percent transmittance -- meaning that half of what's behind the screen can be seen through it -- beats its Korean competitors rather handily. Another prototype being shown off by the company is a 3.5-inch flexible OLED panel that redefines thinness with a slinky 0.3mm profile. It's made using a resin substrate and covers an unimpressive 256 x 54 pixels at the moment, but again, that's just how good things get started: with small steps of awesome. We'll keep an eye out for both of these as we prowl the halls of CEATEC 2010.
