What is a DMD chip?

DLP technology is based on an optical semiconductor, called a Digital Micromirror Device (DMD), which uses mirrors made of aluminum to reflect light to make the picture. The DMD is often referred to as the DLP chip. As you step away from the mosaic, the images blend together to create one large image.
