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,^[1][2] and which may mimic more closely the way the brain processes color information.^[3][4] The screen is a form of multi-primary color display, other forms of which have been developed in parallel to Sharp's version.^[5][6]

The technology is used in Sharp's Aquos LCD TV product line, particularly in models with screens 40 inches across and larger. It was at first introduced as “sub-pixel color technology” and then later coined into Quattron technology by Linda Lim from Sharp Malaysia.^[7] 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".^[8] Another commercial had Takei advertising the 3-D model with the Minions from the 2010 movie Despicable Me.^[9] In Malaysia, the famous tagline was “4C has arrived, 3C is over” mimicking the attention of 4G technology trend at that moment, but was actually referring to its advanced color technology. The later version was known as Quattron Pro with further subdivided pixels applied to its HDTV range.
