What is a DLP projector and how does it work?
A DLP projector is a type of projector that uses a digital light processing technology to display images. It works by using a digital micromirror device (DMD) chip, which is made up of thousands of tiny mirrors that reflect light to create images. The DMD chip is combined with a light source, such as a lamp or LED, and a color wheel to produce a full-color image.
The mirrors on the DMD chip are tilted to either reflect light towards the screen or away from it, creating a pattern of light and dark that forms the image. The color wheel is used to add color to the image by filtering the light through different colors, typically red, green, and blue. The resulting image is then projected onto a screen or surface, creating a clear and vibrant display.
