An liquid-crystal display panel is illuminated by one or more xenon flash tubes as a backlighting source. The LCD backlight includes a back reflector, a reflecting cavity, and a light diffuser. The LCD panel is illuminated by triggering a flash of light from the xenon flash tube at a given frequency, reflecting the flash of light off of a back reflector, and diffusing the flash of light through a light diffuser. Flash lamp drive circuitry controls the triggering of a flash of light from a xenon flash lamp.
