Sharp shows 3-D touchscreen displays for mobile devices

Apr 02, 2010 By YURI KAGEYAMA , AP Business Writer

(AP) -- Sharp's latest 3-D displays deliver bright, clear imagery without the cumbersome glasses usually required for such technology. Now the bad news: They only work on a 3-inch (7.5-centimeter) screen held one foot (30 centimeters) from the viewer's face.

Sharp Corp. demonstrated liquid crystal screens Friday for mobile devices that showed 3-D animation, touch-panel screens that switched from one 3-D photo to another and a connected to a 3-D video camera.

Movies and TVs in 3-D are no longer surprising. Sony Corp. and Pansonic Corp. of Japan, as well as South Korea's Co. and , already sell or are planning 3-D TVs.

The drawback until now has been the need for special glasses, which show different images to the right eye and the left eye. Sharp's 3-D technology doesn't require them because the displays are designed to shoot different images to each eye.

The technology may be applied to TVs in the future, said Executive Managing Officer Yoshisuke Hasegawa. But he acknowledged it now works better when the distance between the viewer and the screen is fixed.

The smaller displays, shown Friday, are intended for mobile devices such as cell phones, game machines and digital cameras.

The 3-D animation on the handheld screen looked like a miniature version of the 3-D animation we are used to seeing on larger TV screens, though images were less convincing than those seen in a darkened cinema.

Photos on the touch screen were less clear and even a bit blurry from certain angles, though Sharp said its latest technology does away with such "ghosting" effects.

Still, the system promises gaming and technology fans the potential for pop-up e-mail messages and taking 3-D photos of friends.

The technology is likely to show up in the next DSi portable game machine, which Nintendo Co. says will be 3-D. Sharp refused to confirm the names of companies it was supplying.

Sharp expects 3-D to replace two-dimensional displays the same way color replaced black-and-white in movies and television.

"The arrival of mobile 3-D is just around the corner," Hasegawa told reporters.

Sharp tried to sell 3-D products in the past but failed, largely because of poor image quality. This time, the Osaka-based company has made breakthroughs for displays that are twice as bright and clear as existing 3-D displays.

The displays can continue to show 3-D images when they are turned to the side, a key feature for smartphones, according to Sharp. Mass production of the 3-D LCDs is set to start in the first half of fiscal 2010, which began April 1, it said.

Excuse me while I get something off my chest....

"Oh my gosh! The next decade is going to be amazing!!!"

Sorry, I'm back. I am really seeing the exponential technology growth happening. It seems like they are making breakthroughs every year that would have taken 10 years last decade. I expect that by the end of the decade we will have absolutely amazing and breathtaking mobile devices. Advanced batteries,graphene processors, 3d displays. Hopefully these displays fix our current problem; the ever growing screen size of mobile devices. We need technology that is portable, but can provide large displays when desired.
