You will find two primary technologies being used by digital projectors. Liquid crystal display (LCD) is the older technology, with separate see-through panels for every single constituent primary color (RGB or red, blue and green.) The image transmission is dependent on the signal acquired from the projector through the laptop or computer, which then redirects the light signals into a screen. LCD projectors look quite much like older slide projectors and are generally built on a straightforward manner. For this reason, they are priced lower compared to their successors which are the DLP projectors.
Texas Instruments developed the Digital Light Processing (DLP) technology in the eighties. DLP projectors usher in a significant impact on image projection. DLP projectors, compared with their predecessors, take advantage of tiny mirrors or micro mirrors to reflect light images to move across the digital projector lens and onto a display screen. Every single mirror is often considered as a pixel image. The mirrors reflect principal colors in a fast rotating sequence, as actuated by a rotating color filter wheel. In unison, the micro mirrors are identified as DMD or digital micro mirror device.
For better picture resolution, the rotating wheel is furnished with a plain patch which enables ordinary white light to go into. Such type of DMD projectors are often called single chip projectors. The three chip digital projectors are a little bit challenging, though they deliver better resolution. At this point, a prism splits the light within the lamp into primary colors, that will be redirected to DMD, thereafter recombines them ahead of projecting across the lens.
DLP projectors are lighter in weight and provide more efficient images. A single chip covers 16.7 colors whilst the three chip model does a massive 35 trillion colors. That is a myriad of colors loaded in a number of digital projectors.
Texas Instruments is the company that owns the patent for DLP technology. Fraunhofer Institute of Dresden in Germany developed the same technology simultaneously and markets it as Spatial Light Modulators. HP, Samsung are other market leaders in both LCD and DLP digital projectors.
