In the CRT (cathode-ray tube) of a computer or video monitor an electron beam moves back and forth across the back of the screen. Each time the beam makes a pass across the screen, it lights up phosphor dots (pixels) on the inside of the glass tube, thereby illuminating the active portions of the screen. By drawing many such lines from the top to the bottom of the screen, it creates an entire image. A color CRT uses three electron guns which activate red light-emitting, green light-emitting, and blue light-emitting phosphors.
