The video tutorial explains how projectors create large images on screens, focusing on LCD and DLP projectors. LCD projectors use light beams, dichroic mirrors, and liquid crystal displays to produce colored images. DLP projectors, developed in the 1980s, use a Digital Micro Mirror Device (DMD) with millions of tiny mirrors and a color wheel to create high-resolution images. The tutorial highlights the technology behind projectors, enhancing appreciation for their role in various settings.
