Sharp Aquos: The Sharp Aquos is a range of LCD televisions and component screens made by Sharp Corporation of Japan.  It encompasses small, portable models (e.g. the 13" B series) up to large home-theater screens (e.g. 65" high-definition widescreen models), as well as component screens for portable devices including mobile phones.  Aquos was first released in 2001 with 13", 15", and 20" 4:3 sizes starting, pricing at $1,799.99, $2,999.99, and $4,999.99 respectively.  Since then, the Aquos brand is Sharp's premium LCD line (as Sharp also makes non-Aquos LCD TVs that sell for less), and recently they have been the first series of LCD HDTVs to feature integrated Blu-ray Disc players with the BD-60U and BD-80U series debuting in 2009.  Some Aquos LCD TVs are notable for displaying color in a RYGB color space known as Quattron, which adds a yellow component, as opposed to the standard RGB color space used by most color televisions.  Initial models in the Aquos range were designed by noted Japanese industrial designer Toshiyuki Kita.  George Takei is the spokesman for the line.
