Dude, screw the transparent OLEDs, it's all about transparent circuits, which some Oregon State University scientists seem to have created. The significance, of course, is clear (ahem): you save a lot of space in devices -- especially portables -- when your circuit board is your screen, not mounted on a wafter in a package on a board behind it. Apparently the scientists even expect clear, glass-mounted indium gallium oxide circuitry to ultimately be cheaper to produce than silicon. The military's in on the gig too, the Army Research Office is a project sponsor (as is HP and the National Science Foundation), probably for the project's obvious heads-up display uses. Will we, um, not see this gear any time in the near future? Hard to say, they're only up to 26 transistors in a single array as of yet (compared to the hundreds of millions in chips nowadays), but we'll be waiting.
