Fujitsu tackles e-paper's slow screen speed

Fujitsu has developed an e-paper display that only refreshes the parts of the screen that need it thus speeding up the display of new screens.

Fujitsu has developed a prototype electronic paper screen that tackles one of the technology's biggest weaknesses: the amount of time it takes to refresh the image.

On electronic paper, screens like those used in Amazon.com's Kindle or Sony's Reader for electronic books, it typically takes a second or more to redraw the image on the screen. Sometimes the screen flickers a few times as the new image appears or, as in the case of Fujitsu's cholesteric LCD technology, the image is slowly revealed in a long sweep across the screen -- but it's a long way from the milliseconds required on other display screens.

To tackle this problem Fujitsu has tried to confine the refresh to just the parts of the screen that need to be changed.

It works best in applications where touch-sensitive e-paper displays are used for things like electronic forms, as the company demonstrated at its Fujitsu Forum event in Tokyo on Thursday.

When a user checks a box or writes in a space on the form, only those rows or columns of the display that have changed are refreshed. Those areas are refreshed at the same speed as before, but because a much smaller area is changed, the user perceives an improvement in performance.

The working prototype was a 12-inch display (about the same size as an A4 sheet of paper) with 768 pixels by 1,024 pixels (XGA) resolution.

Fujitsu has been developing electronic paper for several years, and last year began offering sample portable information tablets to customers in Japan that are based on e-paper and include a network connection.

E-paper displays offer several advantages over conventional LCD panels. They can be made almost paper-thin, are easy to read in bright light and only use power when the on-screen image is being changed.

Windows 10 for Business / Dell XPS 13

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

Windows 10 / Lenovo Yoga 910

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.
