On the other hand, DLP chips have been used by projectors for decades, including those in commercial movie theaters. DLP works by shifting microscopic mirrors that reflect light from a powerful lamp. Each of them forms pixels. Then, they pass the reflected light through a color wheel that adds the red, green, and blue that build all the colors. Finally, a series of lenses projects this light onto the screen where you see the images.
Considering that they work by reflecting light, instead of passing it through LCD panels, very little light is wasted in this process. This unique feature gives DLP chips their superiority when compared to LCD projectors. They are brighter, have better contrast, and produce much higher quality picture.
