Mirror Technology

• Believe it or not, DLP technology is based on the unique properties of mirrors. A special optical semiconductor, called a Digital Micromirror Device (DMD), is used in DLP sets and contains thousands of tiny aluminum mirrors. Each mirror is pixel-sized, and they all work together to create the picture you see on screen. Since all the mirrors are laid out flat and side-by-side against the DMD, each mirror can display a pixel-sized part of the image, and the mirrors will work together to form the complete non-colored picture.
  
  

Projection

• Once the DLP chip has decoded the image and the mirrors have been set in place, the image will need to be projected. At this stage, a complete image is formed. The projection process transforms the signal into a grayscale image that is almost ready to hit the screen. However, before each pixel reaches the screen, color must be added to complete the process.
  
  

Color Completes the Process

• In this final step, all of the components of the DLP work together to make the complete image. To add color, an independent light source passes through a spinning color wheel that is then projected onto the image on the DLP chip and then reflected by the mirrors. Although the color wheel has only three different colors (red, blue and green), millions of different colors can be created on-screen when the different colors flash rapidly. Since this process happens so quickly, the human eye cannot see the different flashes and instead blends them to produce the colors you see on-screen.
