    Even though California startup Kateeva demonstrated it could print OLED displays way back in 2010, the printer it used was a prototype meant strictly for show and tell. The age of printed OLED TVs might finally be upon us however, as the company recently unveiled the YIELDJet, a machine it's calling the "world's first inkjet printer engineered from the ground up for OLED mass production." The machine is quite an impressive affair, comprising a shifting slab capable of handling glass or plastic sheets big enough for six 55-inch displays along with custom print heads designed to emit teeny tiny OLED pixels. Why is this a big deal? Due to the oxygen and moisture-hating nature of OLED ingredients, current OLED televisions are built with tricky vacuum evaporation and shadow masking techniques that are too inefficient and wasteful to be inexpensive. The YIELDJet, on the other hand, prints the LEDs in a pure nitrogen chamber to avoid those problems, plus it promises better film coating uniformity as well. This, Kateeva said, will hopefully result in OLED TVs that won't cost an arm and a leg yet still look stunning when hung on your living room wall. Combined with Sony and Panasonic's separate efforts to mass-produce the stellar-looking sets, we certainly hope that day comes sooner rather than later.

  • Kateeva wants to print OLED displays, says they'll be cheaper that way

    Along with affordable solid state drives, OLED panels are among the most universally desired bits of tech today. It's therefore a good idea to prick up our ears and listen when new California startup Kateeva promises to make OLEDs bigger and cheaper with its large-area printing technology. Advised by our old friend Vladimir Bulovic of MIT, the company has gone official with word of its prototype OLED printer, which can produce displays on a scale of 1.8 by 1.5 meters (about six by five feet) at a cost roughly equal to 60 percent of the manufacturing costs of current LCD technology. We say can, what we really mean is that it has shown itself capable of achieving those numbers -- it's still in the prototype stage and won't be sent out to display manufacturers for testing until next year but it's something to look forward to, nonetheless. We advise checking out the Technology Review article for all the gory production details along with a neat video interview with Kateeva co-founder Conor Madigan.
