Projection devices display information by illuminating an image with high intensity light to present the image on a screen. A digital light processor or DLP in common use today employs a digital micromirror device (DMD) to selectively reflect light to produce an image. In a digital light projector, a light engine directs white light from a lamp onto a color wheel producing red, green, blue and white light. The colored light is then passed to a digital micromirror device (DMD). The light is reflected off of an array of perhaps millions of microscopic mirrors on a DMD chip. This chip is a micromechanical device that selectively tilts the mirrors to reflect the light in a desired pattern. The mirrors on the DMD chip tilt as needed to reflect the appropriate quantity of each color of light to produce the desired color at a given pixel location. DLP projectors utilize transmission lenses to perform projection. DLP projectors use optics including mirrors and lenses to perform projection, and have a color wheel that rotates through the projected light beam. The color wheel includes red, green, and blue filters, and rotates in sync with the refresh rate of the video signal to sequentially provide red, green, and blue light for reflection. The color wheel is synchronized with a DLP processor chip that controls the components as appropriate to generate a color display. Basically, a digital light projector (DLP) is a high-brightness system developed based on digital light processing (DLP) technology. The DLP projection display is typically provided with a spatial light modulator (SLM) unit. A spatial light modulator unit comprises at least one spatial light modulator modulating incident light in a spatial pattern corresponding to an electrical or optical input.
