NEW TOUCHSCREENS MEAN LONGER BATTERY LIFE

02-12-2015

Touch screens have gone from being a way of the future to an everyday utility. In latest news, scientists in the UK have created a new type of touch screen that needs little power to light up.

The technology developed by Bodie Technology, a spin off from the University of Oxford is relatively new.

It has, however found its way into talks with some of the largest consumer electronics companies to see if the new touch screen material can replace the LCD touch screen in the next few years, possibly brining an end to daily phone charging. 

"We can create an entire new market," Peiman Hosseini, one of the researchers.

"You have to charge smart watches every night, which is slowing adoption. But if you had a smart watch or smart glass that didn’t need much power, you could recharge it just once a week."

The new display is made from germanium-antimony-tellurium, or GST. At this time the researches have not revealed much on how the technology is made, but they have described it as a “rigid or flexible display can be formed from microscopic 'stacks' of GST and electrode layers.” In a report published earlier.

Each one of these stacks are a 7-nanometre-thick layer of GST placed between two layers of transparent electrodes that is then fed a very low energy electric current to produce colour images.

It has been reported that the new material can produce vivid colours that display at high resolutions even while in direct light by manipulating incoming light.

"This makes them potentially useful for 'smart' glasses, foldable screens, windshield displays, and even synthetic retinas that mimic the abilities of photoreceptor cells in the human eye," says the team.

The energy requirements to fuel the display are minimum meaning that the tea can cut down on the power consumption of the smart device.

At this time there have been no official announcements of partnerships, but the team is hopeful to have the first prototype ready in 12 months.
