OLEDs blue, bluer

The good news about the successive OLEDs. After rumors that LG is launching OLED TVs of 55 "late 2011 and Samsung OLED 65" in 2012, now that researchers at the University of Michigan managed to double the light output and longevity of blue OLED. The researchers used the power of computer simulations to try many variations of the molecules already employed.

They were able to identify the mechanisms that control the efficiency of light emission of OLEDs. The simulation results were confirmed in practice: the new compounds have a blue OLED luminous efficiency (defined as the ratio between the amount of electric current supplied to the OLED and the amount of emitted light) of 9.4% is almost twice the previously accepted limits.

TDJ: IB-B-318STU3, ThermoLab TRINITY

Our fellow Cowcotland recently posted a review of ThermoLab Trinity, a cooling system for processors in LGA and 775/115x/1366 AMx ... Our fellow Cowcotland recently posted a review of ThermoLab Trinity, a cooling system for processors in LGA 775/115x/1366 and AMX. Relatively compact, cooler consists of an aluminum radiator crossed by several copper heat pipes and a fan of 135 mm, while weighing up to 735 grams on the scale.

GIGABYTE 3TB + Unlock: Available for download.

Gigabyte, one of the leading manufacturers of motherboards, graphics cards and other devices has GigaByte tool 3TB + Unlock. This tool allows motherboards that do not have the EFI Hybrid recognize and use unallocated space on hard drives or over 3TB. GigaByte 3TB + Unlock will optimize the storage space allowing the user to create a virtual drive with a larger than 2048GB, which is the maximum capacity that can recognize a 32bit operating system like Windows XP.

Intel launches Atom Z670 "Oak Trail

While the first quarter of the year draws to a close, Intel has decided to launch its first model of Atom "Oak Trail, the Z670. Aimed at netbooks and touch pads, this includes Lincroft Atom single-core processor (but dual-threaded) running at 1.5GHz, GMA 600 graphics chipset, a memory controller and 512 KB of L2 cache.

Featuring a 3-watt TDP, the Atom Z670 is capable of playing videos properly in 1080p. Many manufacturers such as Samsung and Fujitsu, have already announced they would launch various products based on this platform. But by proposing - a priori - the chip at a rate of 75 million, three times the price of NVIDIA Tegra 2, we can not really say that Intel targets the "low-cost ...

PCI Express 16x is it necessary?

Introduced a long time but steadily undermined by the news (including P67 and Crossfire), we wanted to determine if the PCI Express 16x always prove necessary or if it was feasible to use an interface 4x 8x see that with either one or two cards in Crossfire.

Mac OS X would be Golden Lion Master

One month after the release of the Preview of Mac OS X 10.7, developers argue that Apple is preparing to leave the Golden Master 1 or GM1. If confirmed, marketing at WWDC (June) would more than likely. For more information on Mac OS X 10.7, please read our photo essay "What we reserve Mac OS X Lion." With Snow Leopard, Apple had released the Golden Masters a few weeks prior to marketing, which we were encouraged to compare it to the RTM version of Windows (Release to Manufacturer) (see "Mac OS X Snow Leopard on sale August 28? ").

Your smartphone just weaken your bones

Argentine researchers conducted a study concluding that cell phone signals reduced bone mineral density of people using them frequently, undermining the most exposed to the phone. Research has measured the bone mineral density of 24 men not using mobile phones and other 24 smarpthones wearing their belt, on the right side.

After a year, scientists have noticed that the subjects had a cell phone with bone density at femoral neck right below the left side. A systematic difference which was not present in subjects without wireless device. The differences were not dramatic, but still visible and seems to prove the harmful effects of electromagnetic waves but limited to the body, especially bones.
