You may have one or more projectors at home, but do you know how does a projector work?
The basic principle of the projector is to shine lights on the display element of the image, so as to produce the image, and then through the lens to project.
The display element of the image of the projector consists of the transmission type which produces the image by pervious to light and the reflection type which produces the image by reflected light. But no matter what type, it is the same. The light of the projection lamp is divided into three colors, namely red, green and blue, which are often referred to as the three primary colors, and then the images of various colors are produced according to these colors.
Finally, the three-color images are combined into one image through a prism, and the final lens is projected onto the screen.
