How Do Computer Projectors Work?
Introduction There are many different types of computer projector: CRT, DLP and LCD, to name a few. The one best known is the Liquid Crystal Display projector. The LCD projector uses heat from a halogen bulb to convert the crystal into liquid so that images are displayed in a fluid motion. In this article, we will learn the technology behind the LCD computer projector and see how it works. How Does It Work? There are three panels inside the LCD projector. The halogen bulb is placed in the center so that the panels surround it. It is the job of the panels to produce light. The crystals melt when the halogen bulb heats up, allowing light to pass through. The intensity level of the halogen bulb determines the tone of the images; more heat from the bulb brings lighter tones. Electric voltage that travels through the projector controls the heat produced by the halogen bulb. The projector connects to the computer and acts as a monitor. The images travel through the cable connected to the com
