What Are DLP Projectors?
Just when it seemed that LCD technology had advanced projectors as far as they could go, along came DLP (digital light processing) projectors. Where LCD projectors use liquid crystal panels to display images, DLP uses thousands of microscopically small mirrors, which not only move pixels closer together for higher contrast and greater clarity, but also provide greater brightness than LCD projectors. DLP’s high resolution makes it ideal for projecting images or videos in HD (high definition). Like LCD projectors, many DLP projectors also feature audio. 3 Features To Consider When Buying an Overhead or Opaque Projector 1. Lens Type. The most significant factor in overhead projection image quality is the type of lens being used. The three most common lens types are singlet, doublet, and triplet. Image quality increases as you progress from the basic singlet lens type, to the advanced triplet lens type, though price generally increases as well. 2. Brightness (Lumens). Each overhead project
