Sharp said Wednesday 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 Sharp Aquos Pad SHT21 tablet has a 7in IGZO display with a resolution of 1280 pixels by 800 pixels. Sharp is a known supplier to Apple.

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 SH-02E, 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. Both the phone and the tablet will only be sold in Japan.


Sharp, which is struggling through a management crisis as it tries to finalise 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.
