OLED mini projector prototype for mobile phones using a series of lenses developed


Researchers at the Fraunhofer Institute -- partnered with project HYPOLED -- have created an OLED mini projector prototype for mobile phones. Unlike many previous iterations of similar technologies, this new prototype doesn't need an additional illumination system, instead relying on a lens system to project images produced by an OLED onto a screen or wall -- making it both smaller and more energy efficient. The prototype currently displays a monochrome image with a brightness of 10,000 candelas per square meter, and color images with a brightness of about half of that. The lenses are also made of glass at this point, though cheaper and simpler plastic ones are in the works. No word on when we might see these prototypes hitting the streets in actual projector phones, though.

Laser Matrix instructions will help you make an incredibly facile projector of your iPhone


A clever DIY-er wanted to add some semblance of projector capability to his iPhone, without -- you know -- actually adding a projector to his phone. He chose instead to use the phone in tandem with a 5 x 7 laser matrix, five 8-bit D latches for controlling the laser pointers, a microcontroller, and a bit of (somewhat complex looking) code for the iPhone, resulting in the ability to "spell" out messages on a wall, or other surface. There's a super exciting video demo after the break -- check it o-u-t.

New display tech could make mobiles "glanceable"

We hesitate to bring up anything to do with the ongoing debacle that is SPOT, but the guys over at Microsoft's most left-of-center division helped popularize the concept of "glanceable" information -- ubiquitous, high-demand data (weather reports, for instance) that can be gleaned quickly and with little or no user input. Cellphones, despite the fact that they have ready access to such data, have been largely left out of the party; always-on displays are a backbone of the glanceable concept, and the dazzling, hi-res screens necessary to keep the modern consumer entertained drain far too much power to be left on when no one is interacting with the device. Manufacturers have taken baby steps to solving the power problem by introducing OLEDs, but more is needed. Qualcomm, when it's not busy filing lawsuits, has been working on its iMoD (short for Interferometric Modulator) technology, which uses an array of microscopic mirrors to stay highly visible in well-lit conditions. Meanwhile, Philips spin-off Liquavista is taking the electrowetting approach. Either way, we're all for always-on cellphone displays that afford us more than a few hours of standby, but both groups have yet to name any commercial devices in the pipeline. In the meantime, there's still a chance to jump on the glanceable bandwagon -- grab a handful of Ambient Orbs, turn down the lights, and soak in the psychadelic data.

Samsung SDI creates new 3D AMOLED display

Looks like Samsung's got a new display technology they want to get into cellphones and handhelds; their 4.3-inch active matrix organic light-emitting diode (AMOLED) promises to be the "the world's highest definition" portable 3D display. There they go with that world's-blank crap again -- ok, we get it Samsung, jeez, you're a worldwide innovator. But for crying out loud, at least tell us just how high resolution this thing is, and what exactly it does differently than other portable 3D displays, okay? Keep an eye out, we're sure to hear more about this soon.
