Why is neon in computer screens?

Neon is used in some computer screens, particularly in older cathode-ray tube (CRT) displays, primarily for its ability to emit bright light when electrically stimulated. It serves as a gas that ionizes and produces a vibrant glow, allowing for the display of images. However, modern screens, like LCD and LED displays, have largely replaced neon due to advancements in technology and energy efficiency. Neon is more commonly found in signage and decorative lighting rather than in contemporary computer displays.
