OLED Technology Brings The Flexible Screen
Flexible screens have been in the que for awhile now, but hitting the mainstream market running, has to be difficult. Not since Apple's Iphone have we seen a game changer hit the ground running in the middle of a technology sprint. Now leaders like Samsung are trying to follow up a tough act. At least in the sense of sticking the landing. Much like knowing that the worlds fastest man is in the Olympics, knowing that Samsung has had a viable flex screen created still has to be seen. We want to see if it can enter the market with minimal flaws and show well out of the gates.
The basis is from OLED technology or organic light emitting diode displays. This is a fun technology that you should look up on Youtube here. it will soon allow for a whole new ability to interact with technology and live with it. It seems to me that technology is morphing closer and closer into a life form, merging with our need for it to be one with us, no matter if we consciously want that and all of its scarey implications or not. It is simply the direction we are heading and the inertia is not going to be impeded upon by human conscious-it will only gain speed with human desire.

Bringing this new technology to the surface via smartphones will be smart way of going, at some point I wonder when we are going to find ourselves not just embracing fun new technologies, but also being faced with moral crisis that are tied to it. For now Samsung is bringing out a fun new concept to a key feature of our tech world a flexible display, but we are not far from human integrated technologies that are invasive.

A crack team of engineers at the University of Illinois has developed an electronic circuit that autonomously self-heals when its metal wires are broken. This self-healing system restores conductivity within “mere microseconds,” which is apparently fast enough that operation can continue without interruption.

The self-healing mechanism is delightfully simple: The engineers place a bunch of 10-micron (0.01mm) microcapsules along the length of a circuit. The microcapsules are full of liquid metal, a gallium-indium alloy, and if the circuit underneath cracks, so do the microcapsules (90% of the time, anyway — the tech isn’t perfect yet!). The liquid metal oozes into the circuit board, restoring up to 99% conductivity, and everything continues as normal. This even works with multi-layer printed circuit boards (PCBs), such the motherboard in your computer, too. There’s no word on whether this same technology could one day be used by Terminators to self-heal shotgun blasts to the face, but it certainly sounds quite similar.

Self-repairing electronic chips are one step closer, according to a team of US researchers.

The group has created a circuit that heals itself when cracked thanks to the release of liquid metal which restores conductivity.The process takes less than an eye blink to bring the circuit back to use.The researchers said that their work could eventually lead to longer-lasting gadgets as well as solving one of the big problems of interplanetary travel.The work was carried out by a team of scientists and engineers at the University of Illinois at Urbana-Champaign and is published in the journal Advanced Materials.The process works by exploiting the stress that causes the initial damage in the chips to break open tiny reservoirs of a healing material that fills in the resulting gaps, restoring electrical flow.

Cracked circuits

To test their theory the team patterned lines of gold onto glass to form a circuit.They then either placed microcapsules 0.01mm wide directly onto the lines or added a thin laminate into which they embedded larger 0.2mm microcapsules.In both cases the microcapsules contained eutectic gallium-indium - a metallic material chosen for its high conductivity and low melting point.This device was then sandwiched between another layer of glass and acrylic and connected to electricity.The researchers then bent the circuit until it cracked causing the monitored voltage to fall to zero.They said the ruptured microcapsules then healed most of the test circuits within one millisecond and restored nearly all of the measured voltage.The smaller capsules healed the device every time but were a little less conductive than the larger ones which had a slightly lower success rate. The team suggested that a mix of differently sized capsules would therefore give the best result.The devices were then monitored for four months during which time the researchers said there was no loss of conductivity.

Windows 8: 5 Questions About Microsoft's New OS

This week 

Jun 2, 2011

, Microsoft revealed a little of what to expect from the next Windows operating system. With its Windows Phone look and touch - literally - and tiles everywhere, it will be a major refresh, but there's a still a number of unanswered questions. Here are my top five:

Can Microsoft keep desktop users happy with Windows 8?

In demonstrations this week, Windows 8 is shown running legacy applications like Office side-by-side with the hip new OS. But the version of Windows 8 that runs on the ARM processor won't have legacy support. That creates an OS quandary.

While Microsoft says Windows 8 is backward-compatible, if I want to take advantage of the most revolutionary features -- namely touch and tablet functionality -- I'll need all new hardware and probably software, too. So where does that leave Windows users who want all the old desktop-oriented bells and whistles that shipped with Windows 7 with the new tablet-oriented Windows 8 OS?

A rollable display is a flexible display that can be rolled up into a scroll.

Technologies involved in building a rollable display include electronic ink,Gyricon, and OLED.

Electronic paper displays which can be rolled up have been developed by E ink. At the CES 2006 Philips showed a rollable display prototype whose screen can retain an image for several months without electricity. As of 2007 Philips Polymer Vision expected to launch a 5 inches (130 mm), 320 x 240-pixel resolution rollable display based on E-ink's electrophoretic technology.

Some flexible OLED displays have been demonstrated, Perhaps the first commercially sold flexible display was an Electronic paper wristwatch

A rollable display is an important part of Roll away computer.

Seymour Roger Cray (September 28, 1925 – October 5, 1996) was an
American electrical engineer and supercomputer architect who designed
a series of computers that were the fastest in the world for decades,
and founded Cray Research which would build many of these machines.
Called "the father of supercomputing," Cray has been credited with
creating the supercomputer industry.

The second revision to the universal serial bus USB is out..
USB 3.0 with a speed of 5gb/s which is above 10 times faster than the existing 2.0 version of the same..
this version is really power efficient when compared to the previous version and is also compatible to the earlier version..altogether a good step..
