This statement is true. On older CRT (cathode ray tube) monitors, a static image displayed on the screen for a long period of time could cause burn-in, which is when the phosphors that make up the image become permanently damaged and leave a faint, ghostly image on the screen even when the computer is turned off. Screen savers were initially designed to combat this issue by displaying moving images or patterns that prevented any one area of the screen from remaining static for too long. However, modern LCD and LED computer screens do not suffer from burn-in, so screen savers now primarily serve as a security measure or simply as a fun visual distraction.
