Quattron

Quattron is the brand name of an LCD color display technology produced by Sharp Electronics. In addition to the standard RGB (Red, Green, and Blue) color subpixels, the technology utilizes a yellow fourth color subpixel (RGBY) which Sharp claims increases the range of displayable colors,〔("Sharp Promises Quattron TV Will Wow" CNET Asia, March 23, 2010 )〕〔("Sharp Quattron LC-46LE820M" review by Ty Pendlebury, 16 July 2010, CNET Australia )〕 and which may mimic more closely the way the brain processes color information. The screen is a form of multi-primary color display, other forms of which have been developed in parallel to Sharp's version.〔(parallel LCD design from Genoa Color Technologies website )〕〔(multi-primary color display research from GCT )〕
The technology is used in Sharp's Aquos LCD TV product line, particularly in models with screens 40 inches across and larger.〔(Aquos product information at Sharp website )〕 The technology, distinct from the product line, has been advertised featuring George Takei as the spokesperson in the debut commercial, in which he uses his catchphrase "Oh My".〔(Sharp Press Release: Sharp National Brand Advertising Campaign Adds Color to Dynamic HDTV Landscape – "You Have To See It, To See It" )〕 Another commercial had Takei advertising the 3-D model with the Minions from the 2010 movie "Despicable Me".
==Criticism==
According to an analysis published in MaximumPC Magazine by Raymond Soneira, president of DisplayMate Technologies, a video calibration equipment producer, Sharp's Quattron technology does not have the ability to show more colors than a standard RGB set. He argues that, due to industry-standard color spaces used by content providers, there is no existing source material that contains the fourth color channel. He further states that any "extra" colors displayed must simply be created in the television itself through video processing, resulting in exaggerated, less accurate color.
