    DLP:
    A technology from Texas instruments.
    A chip has literaly Thousands of microscopic mirrors mounted to it. Theses mirrors are fixed to microscopic motors that wiggle the mirrors back and forth. A projector bulb is focused onto the chip and light is reflected from the mirrors to a screen. When theses mirrors wiggle, they reflect light towards or away from the screen. A black and white picture can be created from theses thousands of mirrors. To get color, a color wheel rotates in front of the lamp; alternating from red, green, blue and white. In more expensive modles of these TV's and projectors, there are three chips, dedicated to each color.
    pros: Great picture quality in high densities, good contrast ratio
    Cons: larger than LCD and Plasma, less bright, "rainbo effects" and limited viewing angle

    LCD: Liquid crystal display
    Consists of a glass sandwich that houses thousands of pockets of a liquid crystal substrate. These pockets, when applied to electricity, block or allow light through. A light source (usualy a cold cathode or florecent light, in rarer cases, white led's) are placed behind the glass. Color is produced by grouping LCD pockets in red blue and green close together in a repeating pattern.
    Pros: Slim, High definition, electriacly effecient, newer technology allows for a wider viewing angle, brighter picture and better contrast ratio
    Cons: not the brightest picture available, limited viewing angle in most "affordable modles"

    Plasma:
    For simplicity sake, plasma can be described as a large glass panel that consists of thousands of pockets in groups of red, blue and green filled with flourecent gasses. These gasses act like a florecent bulb when electricity is applied.
    Pros: Brightest picture, HD capable, highest possible contrast ratio, widest viewing angle, capable of 24p mode wich simulates the way film works; giving the best cinimatic picture.
    Cons: More expensive, The blue is subject to burnout before other colors, overal is subject to "burn ins" making this tv less favorable for PC and media center hookup where the backround picture never changes.
