Sharp announces 'four colour' 3D TV launch for this summer.

Sharp's new products will be the world's first 3D TVs using four-primary-color technology. This technology, which was first announced at CES Las Vegas in January, utilizes yellow pixels on top of the three conventional primary colors of red, green and blue. 

Sharp Corporation, in a statement, says its four-primary-color 3D LCD features the industry’s highest brightness with extremely low crosstalk (undesirable double-contour “ghost” images).

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 what the company claims is a radical new solution to the above problems by combining four of Sharp’s proprietary LCD technologies, including UV2A technology, Sharp’s core technology for LCD TV panels, four-primary-color technology, FRED technology, and side-mount scanning LED backlight technology.

The company says 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.

Reuters reports that Sharp will begin selling the new 3D TVs in Japan this summer.
