HDTV Display Types

CRT CRT stands for Cathode Ray Tube.
DLP DLP is a technology made by Texas Instruments. It uses a Digital Micromirror Device (DMD) which has approximately one million tiny mirrors to reflect light that creates a digital image. This is considered to be the best digital picture you can get! DLP is said to have a fill-rate of 88%. The fill-rate is determined by how much of the image is made up of elements compared to the space in between the elements. Thus, 88% means the screen is 88% full of color, while 12% of the image is in between those elements.
LCD LCD stands for Liquid Crystal Display. It has millions of individual LCD elements that are turned on and off to create the colors Red, Green, and Blue. If an element is turned on, light is projected through that specific LCD cell and you see the corresponding color. The fill-rate of LCD is said to be 83%.D-ILA is a type of LCD display that is owned by JVC. D-ILA, unlike LCD, uses a method of reflecting light through the elements twice before being passed to the lens. The fill-rate of D-ILA is said to be 93%.LCOS stands for Liquid Crystal on Silicon and is very similar to the technology of D-ILA, but is instead owned by Hitachi.
Plasma A plasma screen is different in that it contains millions of compartments that contain noble gases such as Argon, Neon or Xenon. To turn these pixels on a current is passed into the compartment and they turn red, green or blue. This is the exact same technology that is used in Neon signs, except a neon sign usually only has one or two compartments of gas, whereas plasma screens have millions.
