Laser-powered phosphor display

Laser Phosphor Display (LPD) is a large-format display technology that is similar to cathode ray tube (CRT) technology but uses lasers instead of an electron gun to activate the phosphors that create the images. LPD was invented and patented by Prysm, Inc. LPD competes with liquid crystal display (LCD), plasma display panel (PDP), and other large-format display technologies.
