Microfilter tubes feature red, green and blue primary color filters made of superfine pigments inserted in between the corresponding color-emitting phosphors and an untinted faceplate of the CRT display. The result is a 30% increase in both brightness and contrast over our conventional CRTs.
While the purple-looking "Lavender Mask" outer surface coating was in use as early as 1989 in Toshiba's Bazooka series (as a "Black Enhancer"), the first microfilter tubes appeared much later in 1995. Microfilter tubes evolved over the years with iterations such as microfilter 98 and microfilter 991, and they used varying Black Enhancer surface coatings, ARECS, ARECS575, and Super ARCAS, which give them a purple appearance when the set is off.
