SHARP'S latest 3D 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 30 centimeters from the viewer's face.
Sharp Corp demonstrated liquid crystal screens yesterday for mobile devices that showed 3D animation, touch-panel screens that switched from one 3D photo to another and a display connected to a 3D video camera.
Movies and TVs in 3D are no longer surprising. Sony Corp and Panasonic Corp of Japan, as well as South Korea's Samsung Electronics Co and LG Electronics, already sell or are planning 3D TVs.
The drawback until now has been the requirement to wear special glasses, which show different images to the right eye and the left eye. Sharp's 3D 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 yesterday, are intended for mobile devices such as cell phones, game machines and digital cameras.
The 3D animation on the handheld screen looked like a miniature version of the 3D 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 3D photos of friends.
The technology is expected to appear in the next DSi portable game machine, which Nintendo Co says will be 3D.
Sharp refused to confirm the names of companies it was supplying. Sharp expects 3D to replace 2D displays the same way color replaced black-and-white in movies and television.
"The arrival of mobile 3D is just around the corner," Hasegawa told reporters.
