Sharp Develops the World's First*1 Four-Primary-Color 3D LCD

On April 12, 2010, Sharp held a press conference in Tokyo to present its new four-primary-color 3D LCD technology.

Sharp has developed the world's first four-primary-color*2 3D LCD featuring the industry's highest brightness*1 with extremely low crosstalk (undesirable double-contour "ghost" images). By wearing special 3D glasses, viewers can enjoy impressive 3D images with an exceptionally realistic sense of depth.

A scene from the press conference

The newly developed 3D LCD combines four of Sharp's unique, one-of-a-kind LCD technologies, including (1) UV2A technology*3, Sharp's core technology for LCD TV panels, (2) four-primary-color technology, (3) FRED technology*4, and (4) side-mount scanning LED backlight technology*5. 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*6, and crosstalk is extremely low. Sharp's four-primary-color 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 has created a wide range of LCD application products by developing innovative LCD technologies, and has been the driving force in the flat-panel display market. In the future, Sharp will be exploring new 3D markets by further enhancing its four one-of-a-kind LCD technologies.
