  An OHP, likea film or slide projector, uses light to project an enlarged image on a screen, allowing the view of a small document or picture to be shared with a large audience. In the overhead projector, the source of the image is a page-sized sheet of transparent plastic film (also known as "foils" or "transparencies") with the image to be projected either printed or hand-written or Drawn. These are placed on the glass platen of the projector, which has a light source below it and a projecting mirror and lens assembly above it (hence, "overhead"). They were widely used in education and business before the advent of video projectors. OHP (Overhead Projectors)

  Opaque Projector Opaque projectorsare typically used to project images of book pages, drawings, mineral specimens, leaves, etc. They have been produced and marketed as artists’ enlargement tools to allow images to be transferred to surfaces such as prepared canvas, or for lectures and discourses. Care must be taken that the materials are not damaged by the heat generated by the light source. Opaque projectors are not as common as the overhead projector.

  DLP • (digitallight processing) 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). DLP (Digital Light Processing)

  An LCD projectoris a type of video projector for displaying video, images or computer data on a screen or other flat surface. Overhead and opaque projectors primarily use 19th century technology (electricity and light bulbs), LCD projectors use liquid crystal panels plus the latest computer and optical technology to project both still and moving images in vivid color. Many project ors also have built-in audio speakers, making them all-in- one audiovisual presentation units. LCD (Liquid Crystal Display)

  Interactive Whiteboard/ Smart Board Aninteractive whiteboard (IWB) also known as Interactive board or smart board, is a large interactive display in the form factor of a whiteboard. It can either be a standalone touch screen computer used independently to perform tasks and operations, or a connectable apparatus used as a touchpad to control computers from a projector
