With their excellent display effects, flexible presentation methods, and convenient operation, they have become an indispensable important equipment in scenarios such as meetings, speeches, and teaching. Next, we will provide a detailed understanding of the related knowledge of projectors. I. Basic Principles of Projectors Projectors primarily use the optical system to project light emitted by the light source onto the screen to form an image. They are mainly composed of a light source, an optical system, a projection lens, and a screen. Among them, the light source is the heart of the projector, providing the necessary light for image display; the optical system processes the light through focusing and color adjustment; the projection lens is the bridge connecting the image and the screen, accurately projecting the image onto the screen; and the screen receives the projected light from the projector to present the image. II. Classification of Projectors

According to different usage technologies and display methods, projectors can be divided into LCD projectors, DLP projectors, LCOS projectors, etc. LCD projectors are popular due to their high color fidelity and affordable prices; DLP projectors are favored by enterprise users for their high brightness and long lifespan; LCOS projectors are often used in high-end application scenarios due to their high resolution and excellent color performance.
