Abstract
Displej sa laserskim zracima sadrzi najmanje prvi i drugi skup izvora laserskih zraka (200,300) od kojih svaki moze pogodno da bude grupa poluprovodnickih lasera, koji obezbedjuju skup laserskih zraka u optickom putu tako da se odbijaju od reflektivnih faceta (204, 304) pokretnog reflektora (32) i osvetljavaju ekran displeja (206). U displeju sa bojom, svaka kolona laserske grupe odgovara odredjenoj primarnoj boji. Odvojeni redovi svake grupe odgovaraju nezavisno aktiviranim, ali simultano pobudjivanim skeniranim linijama da osvetle uredjaj za skeniranje sa laserskim zracima. Visestruki laserski zrak deli sirinu ekrana u manje skenirane segmente da se poveca ugao skeniranja ili poveca horizontalna brzina skeniranja uredjaja. Nagnute facete osvetljavaju razlicite vertikalne delove ekrana sa laserskim zracima, kada se reflektor obrce. Sken format, koji koristi simultano osvetljene dijagonalne sken povrsine obezbedjuje optimalno koriscenje grupa visestrukih laserskih zraka.
