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 7.5-cm screen held 30 cm from the viewer's face.
Sharp Corp. demonstrated liquid crystal screens last week for mobile devices that showed 3-D animation, touch-panel screens that switched from one 3-D photo to another and a display connected to a 3-D video camera.
Movies and TVs in 3-D are no longer surprising. Sony Corp. and Panasonic Corp., as well as South Korea's Samsung Electronics Co. and LG Electronics, already sell or are planning 3-D TVs.
