All of these technologies offer many advantages over film and CRT projectors-smaller size, lower weight, less heat generation, and more efficient energy usage-and each one has its own strengths and weaknesses for different applications.
Today, film has been almost completely replaced by digital-video projectors that are based on one of three imaging technologies: LCD, LCoS, and DLP. A lens and associated optical elements, which are used to generate color and project the image onto the screen.This will typically be either a single Digital Light Projection (DLP) micromirror device, a trio of LCD (liquid crystal display) panels or a trio of LCoS (liquid crystal on silicon) chips. An imaging chip or chips that generate the image based on the video source signal.In today’s projectors this will be a traditional lamp, a bank of laser diodes, or a bank of LEDs (light-emitting diodes). A light source that creates the light for the image.In the most simplistic terms, every modern digital projector has three primary components:
