DLP/LCD/LCOS-Digital Projectors

Digital projectors are the modern replacement to more traditional transparency projectors (OHPs). Transparency projectors work by shining light through a semi-transparent material, such as slides or film. Digital projectors project a digital image directly from a computer or other digital devices through a lens on to a screen. They are of three types - DLP (Digital Light Processing), LCD (Liquid Crystal Display) and LCOS (Liquid Crystal On Silicon).
