How does the DLP projection TV technology work?
DLP technology is the main alternative to LCD, LED and plasma screen TVs. The technology relies on a complex mirror system to project images. DLP technology is used in projectors and is one of the most valuable technologies in the industry. The technology is found in standalone projectors like in a movie theater. It also includes projectors that are put inside TVs and used to project images for the unit. These are called front-projection HDTV.

The DLP acronym stands for “digital light processing.” This process takes place in the DLP chip, most notably manufactured by Texas Instruments. The chip sits underneath the mirror system and feeds information to the mirrors. The mirrors respond by displaying the specified colors, forming the images that we see on the screen. What we see is filtered through a lens and formed by various combinations of red, blue, and green light. This is the system that is used in DLP HDTVs.
The projectors function a bit differently. In the standalone units, there are three chips. Each of these works with a different color light. So, there is a chip for red, one for blue, and one for green. In this case, light hits each chip and then is recreated accordingly, making the right combination of light as needed. One of the main concerns with this technology is a color imperfection created by the use of the mirrors. This is called the “rainbow effect” and has to do with the division of light into three colors. Sometimes, users claim to see flashes of the individual colors. Over time, this has become less noticeable due to accompanying technologies involved in video production.

Because of the digital aspects of DLP technology it is very handy in two ways. First is longevity. There are certain problems you don’t have to worry about with DLP TVs. For instance, screen burnout will never be a problem, because digitally produced images just can’t cause that. There are several other features of DLP that make the system lower maintenance and longer living. There is also the fact that the digital technology is small and lightweight. This means that systems using DLP can be smaller and more portable. They are lighter and easier to carry and move around. The benefits of this can be worthwhile to anyone with DLP systems in their house.
