Sharp Develops the Four-Primary-Color 3D LCD TV
Sharp has developed the first four-primary-color 3D LCD featuring the industry's highest brightness with extremely low crosstalk (undesirable double-contour "ghost" images).
The Japanese company said it would begin selling 3D TVs this summer.
By wearing special 3D glasses, viewers will be able to enjoy 3D images with realistic sense of depth, Sharp said.
In general, 3D LCDs use a system based on time-sequential display technology with special active LC (liquid crystal) shutter glasses. In this system, images intended for the left and right eye are displayed on the LCD screen sequentially, alternating between the two perspectives. The LC shutters in the special 3D glasses are synchronized with this display, "opening" (becoming transparent) and "closing" (becoming opaque) in such a way that the left and right eye see separate images. The human brain combines these two slightly different images to create the perception of depth in a three-dimensional image. However, displaying 3D images on a conventional display using this system suffered from low brightness and crosstalk.
The newly developed 3D LCD by Sharp offers a radical new solution to the above problems by combining four of Sharp?s LCD technologies, including the UV2A technology, Sharp?s core technology for LCD TV panels, four-primary-color technology FRED technology, and side-mount scanning LED backlight technology. This LCD is optimized for 3D TV, as screen brightness when displaying 3D images is 1.8 times higher than that of the conventional displays, and crosstalk is extremely low. Sharp's four-primary-color technology utilizes four primary colors, adding Y (yellow) to the three conventional primary colors of R (red), G (green), and B (blue). This technology contributes to brighter, more vivid colors thanks to higher light transmission efficiency through the panel and a wider color gamut (range of colors that can be reproduced), which had been difficult to attain on conventional three primary color displays.
Sharp, the world's fourth-largest LCD TV maker behind Samsung, Sony and LG, said it would launch 3D TVs this summer in Japan.
It said it plans to begin selling them in China, the United States and Europe by the end of this year.
Panasonic and Samsung have already released 3D models, while Sony plans to start offering 3D TVs in June.
Demand for 3D TVs will likely grow more than tenfold to 27 million units in 2013 from an estimated 2.5 million units this year, according to research firm DisplaySearch.
