No-Glasses 3-D Coming To Mobile Touchscreens
If wearing glasses to watch 3-D is less than enticing, Sharp may have an alternative. The electronics company announced Friday that it has developed a high-quality, no-glasses 3-D touchscreen LCD.
The company said the new screen, currently up to 3.4 inches, is "ideal" for such mobile devices as digital cameras and smartphones. Yoshisuke Hasegawa, Sharp's executive managing officer for LCDs, told news media Friday that "just like black-and-white TVs turned color, all displays will eventually be 3-D." The technology can also be used in large TVs, he said, but at the moment there are no specific plans for this kind of product.
The 3-D screen uses a parallax barrier system, which contains a series of vertical slits to control the light reaching each eye. Since the image is slightly different for each eye, a perception of depth is created.
The company said conventional 3-D no-glasses screens with the parallax system, including ones it has produced, have failed to create high-quality 3-D images, but there have been several improvements in the technology.
One improvement resulted from advances by Sharp in CG-Silicon technology, which creates LCDs using high-performance, crystalline silicon with electron mobility much greater than ordinary silicon. The improved CG-Silicon allows more light to pass through the LCD, thus doubling the brightness.
The parallax design has also been optimized, which increases the efficiency of the light and reduces image-doubling created by the overlapping of left and right images. The newer 3-D LCD has about twice the horizontal and vertical resolution as a conventional 3-D LCD screen, twice the brightness, and a contrast ratio about 10 times greater.
In addition, the conventional 3-D LCD display is only available without touchscreen capability, while the new one can be touchscreen or not.
Sharp said the no-glasses 3-D LCD display is scheduled to begin manufacturing...
