  Digital Light Processing is a new way to display and project information. The Texas Instrument, based on the digital micro mirror device, first developed this technology. Digital light processing technology is used for front and back projection units. This technology is mainly based on an optical semiconductor called as Digital Micromirror Device (DMD) that uses mirrors to reflect light to make the picture. These mirrors are made of aluminum and are positioned in a semiconductor chip. The digital micromirror device is referred to as DLP chip. This chip can be easily held in our hand and contains more than 2 million mirrors that measures less than that of the one fifth of the width of the human hair.  Generally the size of the micromirror pitch is less than 5.4µm. The digital micromirror device is a square chip based on Random Access Memory (RAM). On every memory location, there are number of microscopic mirrors. These mirrors sets the resolution for the chip, one mirror equa...
