DISPLAY DEVICE

摘要

A display device includes: a semiconductor laser for emitting an exciting laser beam; a resonator having a solid-state laser excited by input of the exciting laser beam for emitting laser and a first and a second mirror arranged so as to sandwich the solid-state laser; a wavelength conversion element arranged inside the resonator and converting the basic wave laser beam into a higher harmonic laser beam; an image display element for displaying an image by irradiation of the higher harmonic laser beam; and a laser drive unit for driving the semiconductor laser so as to lower the output of the higher harmonic laser beam at a cycle of frame cycle of the video signal applied to the image display element and multiplied by an integer. It is possible to realize a high luminance and a large screen by stabilizing the output of the laser beam applied to the image display element.
