Digital Projector Reviews, Digital Video Projector

To begin with, there are two technologies used by digital projectors. The older technology is the LCD, liquid crystal display with independent transparent panels of LCD for each constituent primary color – red, green and blue. The image transmission depends on the signal received by the projector from computer that redirects the light signals through these LCD panels and lens onto a screen.

The LCD projectors are simple in construction and therefore are less expensive then their successors DLP projectors. Picture clarity in LCD projectors depends on the amount of pixels it is set for.

The next type of digital projectors is DLP (Digital Light Processing) projectors. DLP projectors bring in a paradigm difference in technology in image projection to board rooms. DLP projectors use tiny mirrors or micro mirrors to reflect light images to pass through the projector lens and onto a screen. The mirrors reflect primary colors in swiftly rotating succession as actuated by a rotating color filter wheel. The image of rapidly changing colors provides images for human eye perception. The micro mirrors are collectively called DMD.

For the purpose of improving picture clarity, the rotating wheel carries a plain patch that allows plain white light. The three chip projectors are a bit complicated but provide better clarity. DLP projectors are more lightweight and offer much better pictures.

Commercial Models Texas Instruments owns the patent for DLP technology. Fraunhofer Institute of Dresden of Germany developed the same technology simultaneously. Samsung and HP are other market leaders in both LCD and DLP technologies.

If your digital image projector is having problems, how to fix it can be just a matter of replacing a burnt out bulb, ensuring that all your digital projector cables are properly connected to the entire system. Reflective projectors are the superior digital projectors that provide top quality images. They are affordable in price and offer high level of entertainment. Everyone can enjoy home theater applications due to digital projectors!
