Digital projectors are video projectors that are used in events for presentations. These models of projectors typically get video impulses from desktop or laptop computer systems and display the visuals on large screens. In turn, the presentation can be easily understood by all people in the meeting.
There are two technologies utilized by digital projectors. The older one is LCD or liquid crystal display. It incorporates independent transparent panels for each and every constituent primary color (RGB or red, green, blue). The image transmission depends on the signal picked up by the projector from the laptop or computer, which channels the light signals by means of the panels onto a screen. The LCD projectors look quite comparable to older slide projectors and are elementary in assembly, hence cost much less than the newer DLP projectors.
Digital Light Processing or DLP is an innovation created by Texas Instruments in 1987. DLP projectors bring in a paradigm change in image projection technology to board rooms. In contrast to the earlier versions, DLP projectors utilize tiny mirrors or micro mirrors to reflect light images and traverse the projector lens and eventually onto a TV screen.
For the sake of increasing graphic quality, the rotating wheel includes a plain patch that permits white light. This kind of projector is also known as a single chip kind. The three chip projectors are a little bit complicated but offer you greater quality. In this case, a prism divides the light from the lamp into main colors that are redirected to DMD, which brings them together again prior to projecting through the lens.
What’s the significant difference? DLP projectors are lighter in weight and give greater visuals. The single chip variety handles 16.7 million colors while the 3 chip model can handle 35 trillion colors.
Texas Instruments is the leader that possesses the patent for DLP technology. Fraunhofer Institute of Dresden in Germany developed an equivalent technology as well and sells it as Spatial Light Modulators. HP and Samsung are other market leaders in both LCD and DLP projector know-how.
