On eve of Apple launch event, Japan's Sharp says IGZO devices set to surge

The Japanese manufacturer is betting big on IGZO display technology, which it says can triple battery life in smartphones

Japan's Sharp said Tuesday that mobile devices using its new IGZO display technology, which can triple battery life while offering higher touch sensitivity, are about to surge.

The company decline to provide specific details, but Sharp executive Masami Ohbatake told reporters in Tokyo that the two devices already announced with the technology would soon be joined by many more. In recent weeks, Sharp has announced a smartphone and a small tablet for the Japanese market that have screens employing IGZO, named after the indium gallium zinc oxide semiconductor on which it is based.

The tablet has a 1280 by 800 pixel, 7-inch IGZO display. It has drawn attention ahead of an Apple press event set for Tuesday in the U.S., which is widely expected to announce a smaller version of the iPad tablet with a screen of about the same size. Sharp is a known supplier to Apple, and some rumors have said the new "iPad mini" will use IGZO technology.

IGZO can be used to make screens with smaller pixels than current screens, drawing less power and providing greater accuracy. Sharp says its new Aquos Phone Zeta, scheduled to go on sale by the end of this year, can last two days on a single charge of its 2,320mAh battery under normal usage. Its Aquos Pad tablet, to go on sale in early December, can play video back for 10 hours without a recharge.

Sharp, which is struggling through a management crisis as it tries to finalize an investment deal with electronics giant Hon Hai, is betting big on IGZO. The company is increasing production of display panels for mobile devices that use the technology as part of its shift away from large TV panels, where price competition is much more severe.

The company, which sells few phones abroad, is a major manufacturer of domestic models under its "Aquos" brand, though it has recently lagged behind local rivals such as Fujitsu and Kyocera as well as foreign competitors like Apple and Samsung.

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!

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.

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

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