Samsung adopts metal quantum dot for QLED TV

The Samsung Electronics has adopted Quantum Dot materials in its latest on the shelf QLED Q9, Q8, and Q7 TV series, reports ITRealms.

Business Unit Head, TV/AV at Samsung South Africa, Lance Shaun Berger, said that with the launch came with the belief that this latest range of TVs will create an entirely new era in home entertainment.

“With the advent of QLED TV, Samsung can provide the most true-to-life picture on screen, having been successful in solving past inconsistencies in the viewing experience and consumer pain points. While we are redefining the fundamental value of TV with this range, we have also placed a strong focus on ensuring that there will be models available that will suit the pockets of our customers in the emerging markets,” Berger said.

According to Samsung, with picture quality remaining a top priority for consumers around the world, especially as the average TV continues to increase in size, Samsung’s 2017 QLED TVs represent yet another leap forward. The new line-up offers dramatically improved colour performance. Displaying DCI-P3 colour space accurately and in another world first for Samsung, QLED TVs are capable of reproducing 100% colour volume. This means the devices can express all colours at any level of brightness, with even the subtlest differences visible at the QLED’s peak luminance – between 1,500 and 2,000 nits.

Colour volume presents colour that can be expressed at different levels of brightness. For example, a leaf can be perceived as different shades, from yellowish-green to turquoise, depending on the brightness of the light. Samsung’s QLED TV displays can capture even these subtle differences in colour pertaining to brightness.

“This breakthrough is a result of Samsung’s adoption of a new metal Quantum Dot material, making it possible for the TV to express a significantly improved range of colour, with much greater detail compared to conventional TVs,” Berger explains.

ITRealms gathered that the new Quantum dots allow Samsung QLED TV to express deep blacks and rich detail regardless of how light or dark the scene is, or whether the content is being played in a brightly lit or darkened room. With its metal alloy Quantum Dot technology, brightness no longer has to be compromised to boost colour performance, which is maintained regardless of how wide the viewing angle may be.

Berger further said, there is no reason why African consumers should be left behind by this ground-breaking new technology, which is why “our innovative new QLED TVs have been designed to not only offer a vision of the future, but to do so at a price point that takes into account our many valued customers across the African continent.”

Goodbye fuel: Car running on air, water debuts






An Israeli firm, Phinergy, has created a technology that uses metal, air and water to power a vehicle, reports ITRealms.

Metal-air technology, ITRealms gathered, has been at the forefront of energy research for years, due to its enormous energy potential, thus Phinergy's technological breakthroughs allow it to efficiently utilize this potential for various applications, outperforming conventional batteries.Since 2008, 
Phinergy, benefiting from more than a decade of academic research at Bar-Ilan University near Tel Aviv, has been successfully developing this technology by utilizing the energy stored in metal.

Phinergy’s battery creates energy by combining aluminum and ambient air with water, just as the company experts explained that the difference between this process and other electric-powered vehicles is comparable to the difference between a human scuba diver who must carry his oxygen in a balloon on his back, and a fish, which simply utilizes the oxygen contained in water by breathing through its gills. Due to the unique technology, the battery is immune to CO2-related problems, which, according to Phinergy, has been the leading cause of metal-air battery failure in the past.

One of the most attractive aspects of this technology is that instead of having to refuel with gasoline every several hundred miles, or having to recharge or exchange a battery, the only necessary ingredient for refueling is water – a resource that is widely available, giving these cars a range that is virtually unlimited and making them very cost-efficient.
