Working Principle
DLP projectors beam light through a color wheel, reflection mirrors, then finally a lens. You can view DLP as a technology delivering image using hundreds of thousands of tiny mirrors. These mirrors manipulate light to create an image.
Most of DLP projectors adopts a color wheel, which spins RGB patterns in front of the light source at high speeds.
It can be divided into 3 kinds, say single-chip DLP, 2-chip DLP and 3-Chip DLP, according to the number of reflection mirrors, The technology is based on a deep understanding of the human eye.
DLP projectors Features
It features more pixels for sharper images, which performs better in terms of reflection, contrast, uniformity. It delivers high image definition, uniform picture, sharp color, and stable picture quality, reproducing accurate digital image.
Another advantage of DLP projector is smooth image with large contrast ratio. These advantages make it preferred technology used in home theater area.
Nowadays, DLP projectors usually have a contrast ratio range of 500:1 to 100,000:1. The higher the contrast ratio, the more detail you can see in the image.
DLP and LCD Projector which is better?
The disadvantage of DLP projectors is that they are prone to the rainbow effect, The disadvantage of monolithic LCD projectors is the average contrast ratio.
The biggest advantage of LCD projector is that the three primary colors of red, green and blue are done by 3 separated LCD plates, which can control the brightness and contrast of each color individually, and the three colors of light can reach the screen almost at the same time, so it can truly reproduce various colors.
