Rear-projection CRT televisions are older technology. CRT TV's use three separate cathode ray tubes to create red, green, and blue and the TV combines the three beams before magnifying and projecting the image. The screen quality isn't as good as Plasma or LCD technology.
2.LCD (uses 2 different polarized, transparent panels to house a liquid in the middle.) Flat-Panel LCD TVs (liquid crystal display) technology are designed to create sharp, bright images in any lighting condition. LCD flat screen TV models work by shining light through pixel cells, with each cell containing a red, green, and blue component.
