LAS VEGAS - Sharp is unveiling at International CES the next phase in its Quattron four-color LCD development, including a larger-screen size, more LED edge- and backlit models and second-phase 3D models.
Among the highlights this year is the company's LE732U Quattron (quad-pixel) 3DTV series featuring the huge 70-inch LC-70LE732U (shipping in April at a price to be announced). The set is based on an X-Gen Quattron panel using pixels with four primary colors (red, green, blue and yellow), instead of the conventional three colors, for enhanced color depth.  
The Full HD 1080p/120Hz set uses a full-array LED backlighting system to produce a 6,000,000:1 dynamic contrast ratio.
Included in the set is network connectivity with built-in Wi-Fi reception and access to streaming service partners, including

CinemaNow, Netflix and Vudu. The set also supports Alphaline and Aquos Advantage Live support with DLNA compatibility to link to storage on networked PCs and peripherals.
