Projector technology refers to devices that project images or videos onto a surface, typically a screen or wall. These devices work by using a light source, such as a lamp or LED, to illuminate a digital image created by a computer or media player. The image is then magnified and displayed, allowing for larger viewing experiences in settings like classrooms, offices, and home theaters. There are various types of projectors, including LCD, DLP, and laser projectors, each with unique features and benefits. LCD projectors use liquid crystal displays for vibrant colors, while DLP projectors utilize micro-mirrors for sharp images. Laser projectors offer longer lifespans and better brightness, making them suitable for diverse environments.
