Washington, June 2 (ANI): A predominant mobile phone operator in Japan along with a leading European computer company has doubled the user's pleasure by creating a prototype smartphone that has front and back touch panels and a see-through display.

This smartphone, created by NTT DOCOMO and Fujitsu, gives users the ability to operate applications on both sides of the display at the same time.

You could hold down an icon on the front, and slide on the back to move an icon, or use the message bar, or create a new application, Discovery News quoted Masashi Tagaya, in DOCOMO YouTube video, as saying.

For example from the front, you can only move the whole Rubik cube like this, but if you slide your finger across the front while holding down the back, you can rotate just one face. So this display makes gripping operations possible, he said.

While this technology certainly could expand the capabilities of smartphones, there are still a few tweaks to be made. For example, the display is quite small, but thankfully the developers realize this.

The display is QVGA (320 x 240), at 2.4 inches. We think it needs to be bigger if we're to market this kind of phone.

But even in this form, we think it could be used as a sub-display. In that case, it will have a limited display capability, so we think the range of applications could be wider, he said.

Also on the improvement checklist is the display's brightness. Compared to today's smartphones with vibrant color-popping HD displays, DOCOMO's is cloudy and not very bright. But Tagaya and his crew say they're on top of that. (ANI)
