Sharp Aquos Quattron LC-40LE830U LCD TV
Sharp's main differentiating feature is Quattron, a proprietary modification of the panel design used by nearly all LCDs (both LED-based and otherwise), plasmas, monitors, projectors, smartphones, and so on. All 1080p TVs have 1,920x1,080 pixels, which are typically composed of three subpixels, one each for red, green and blue, that combine to form color. Quattron adds a fourth subpixel, yellow. You can check out our "Oh, myyy!" slideshow from 2010 for more information on the technology, which is largely unchanged this year, and the Performance section of this review for detailed tests.
