Patent attributes
The invention is directed to a microdisplay of an optical device, comprising: a light source; an optical element, disposed on the light exit side of the light source to adjust the light path of the light source; an LCoS substrate, a shape of which exhibits a notch in at least one dimension, the light source projected onto the LCoS substrate, the LCoS substrate reflects the light source entering the notch; and a spatial light modulator, after an outgoing light reflected by the LCoS substrate, the outgoing light enters the spatial light modulator; the spatial light modulator adjusts an azimuth angle of a liquid crystal layer to eliminate noise of the outgoing light; wherein, the outgoing light adjusted by the spatial light modulator is projected onto a eyepieces to display images without the fringe field effects.
