DLP Televisions

DLP TV’s use mirrors (Digital Micromirror Devices) made of aluminum to reflect light, creating a picture. Each mirror reflects one pixel of color. Pixels are the smallest component of a picture, representing a single dot of light.

“Each pixel of light on the screen is red, green or blue at any given moment. The DLP technology relies on the viewer’s eyes to blend the pixels into the desired colors of the image. For example, a mirror responsible for creating a purple pixel will only reflect the red and blue light to the surface. The pixel itself is a rapidly, alternating flash of the blue and red light. Our eyes will blend these flashes in order to see the intended hue of the projected image.” (http://electronics.howstuffworks.com/dlp2.htm)

DLP TV’s can now display 1080p resolution, which can project more than 2 million pixels (1920x1080) which is the highest resolution available today.

Components:

· A CMOS DDR SRAM chip, which is a memory cell that will electrostatically cause the mirror to tilt to the on or off position, depending on its logic value (0 or 1)

· A heat sink

· An optical window, which allows light to pass through while protecting the mirrors from dust and debris
