Researchers devise contact lens with built-in LCD

Another day, another step towards technologically tricked out contact lenses. The latest development comes from researchers at the Centre of Microsystems Technology at Ghent University, who've developed a prototype lens with an embedded, spherical curved LCD that isn't limited to a paltry amount of pixels. As opposed to LED-based solutions which could only muster a few pixels, the newly-developed screen can pack enough to display graphics that cover a contact. In its current form, the display can show simple patterns, and demonstrates the technology with a simple dollar sign. What appears on the lens wouldn't be visible to folks who wear it, however, since eyes can't focus at such a close range. Despite the limitation, researchers are trying to tackle the focusing issue and are assessing the feasibility of a version that would effectively act as a heads-up display. In the future, the tech could be leveraged for medical purposes, such as controlling light transmission to the retina when the iris is damaged, cosmetic uses and -- you guessed it -- HUDs. With the technology's foundation established, it's expected that real-world applications are potentially a few of years away. Hit the jump to catch a video of the tech in action.

Sharp's first 4K 32-inch IGZO LCD is destined for Japanese workstations

We've been waiting to enjoy the promised extra detail and low power consumption of IGZO-based LCD panels for a few years now, and they're finally starting to appear. The latest on the docket is Sharp's new PN-K321 monitor, built for professional use with 4K resolution (3,840 x 2,160) plus HDMI and DisplayPort inputs, and what Sharp claims is the industry's thinnest frame at just 35mm thick. With an expected price of 450,000 yen or so (about $5,500 US) when it debuts in February 2013 it's still too pricey for our desks but if you're doing CAD work you may be able to design a budget it can fit into. We're seeing them inphones, tablets and now monitors overseas, here's hoping we'll see plenty of these high pixel density yet power-sipping panels with US release dates at CES in January.

LG EA93 21:9 aspect ratio 29-inch LCD spotted on IFA show floor (eyes-on)

Fancy a wickedly wide 21:9 aspect ratio LCD that's more than a touch larger than what you'll find on that unique Toshiba Ultrabook? It looks like LG's got you covered, with its 29-inch EA93. We spotted a half dozen of the ultra-wide IPS displays during a preview of the show floor at IFA, and were able to grab a few frames. You need to see this LCD in person to get a feel for just how wide it really is -- with a 29-inch diagonal panel that's incredibly short and squat, you'll be compromising quite a bit of desk real estate in order to add some horizontal pixels.

From booth materials, it seems that LG is promoting this product as a multitasking solution -- the format is well-suited as a replacement for dual-monitor rigs, letting you view several windows at once without adjusting your eyes vertically. We already had a solid grasp on the EA93's specs, which include a 2,560 x 1,080-pixel panel, a four-way split screen feature and plenty of inputs, including two HDMI ports, DVI Dual Link and DisplayPort, though the product placard also revealed USB 3.0 connectivity and 7-watt stereo speakers. Pricing has yet to be confirmed, but if you're prepared to add such a device at any cost, we'd suggest clearing some desk space now -- these are set to ship in November.
