A bright direct view laser phosphor display with a large scanning angle has been developed. A scan mirror, to which a dielectric multilayer was applied on a glass substrate, achieved over 99% reflectivity and withstands large laser power. An optical scanning angle of over +/‐ 21.5 degrees was verified, which was achieved with our dual moving‐magnet drive design. Expansion optics for expanding the scanning angle by 1.5 times were developed. The effectiveness of the proposed devices was verified by projecting images on the display.
