Projector

A projector is a device that displays images or videos onto a large surface, typically a screen or wall, by projecting light through a lens. It takes digital data from computers, cameras, or other sources, and enlarges the visuals to be easily viewed by a group of people. Projectors are commonly used in classrooms, meetings, and home theaters because they can produce large, clear images from compact equipment. They work through various technologies such as LCD, DLP, or LED, which manipulate light and color to create vivid, high-quality images on a flat surface.
