Samsung DLP Protection TV

Samsung DLP protection TV is just one of the many brands of digital light processing televisions now available. DLP is cutting edge technology. The basis for this new technology is a digital micro mirror device or DMD. This processing chip was invented by Texas Instruments in 1987. When it became obvious that the new chip could be used for digital light processing, practical uses for this new technology became possible. One of those uses is Samsung DLP protection TV. The chip is composed of almost two million microscopic hinged mirrors where each mirror is about one fifth the width of a human hair.

To make this chip create digital video in a Samsung DLP protection TV, you must combine the DMD with a light source, a color wheel, a projection lens and a digital video signal. The mirrors are on hinges so they can be turned either toward the light source (ON state) or away from the light source (OFF state). In the ON state the mirror reflects the color of the light. In the OFF state the mirror leaves a dark pixel on the screen�s surface. The digital bit stream in the video signal instructs the mirror to turn on or off as frequently as several thousand times a second. A single DMD chip system can produce 16.7 million colors and a three chip professional system can produce up to 35 trillion colors.

The digital signal coming into the system took the original image and broke it into its red, blue and green component colors for each frame of the movie. Then these components are coded into a digital signal which is then sent to the Samsung DLP protection TV. The digital signal is then read by the processors in the Samsung DLP protection TV circuitry which coordinate the ON and OFF states for red blue and green to produce the correct colors. The human brain and the fantastic optical receptors in the human eye competes the signal processing by blending these rapid flashes of light into the proper colors so that we see the image on the screen.
