What is a projector? & Types of Projectors

Types of Projector

Before diving into the different types of projector, let’s first understand what a projector is and how it works.

What is a Projector?

A projector is a device that takes images from a computer or Blu-ray player and displays them on a screen or wall. Like a magic lantern, it brings digital content to life. But what exactly is a projector, what are the different types of Projector, and how does it work its magic?

This guide looks closely at projectors. It explains how they work and the different types available. It also helps you how to choose the right one for you.

How Does It Work?

A projector is a device that shows pictures or videos. It projects images and videos onto a larger surface, like a screen or a wall. The magic happens through a combination of light and lenses:

1. Light Source: Projectors use either a bright lamp (traditional) or a light-emitting diode (LED) as the light source.
2. Image Processing: The projector receives the image signal from a computer, media player, or other source.
3. Projection System: The light source illuminates the image, passing through a series of mirrors and lenses. These elements magnify and focus the image to create a sharp and clear projection.
4. Projection Surface: The focused light hits the screen or wall, showing a larger image for everyone to see.
