CRT projector

A CRT (Cathode Ray Tube) projector is a display device that projects images onto a screen using three separate CRTs — one for red, green, and blue colors. Inside, each CRT contains an electron gun that emits electrons towards a phosphor-coated screen, creating the respective color. The images from these three tubes are combined through a series of mirrors and lenses to produce a full-color picture. CRT projectors are known for their excellent color accuracy, smooth motion, and high contrast, making them ideal for professional presentations and home theaters, though they are bulkier compared to modern digital projectors.
