Abstract
A wearable display apparatus includes a reflective light modulator having a front, a light guide plate placed at the front of the light modulator, a plurality of monochromatic light sources of different colors, and an optical assembly. The light guide plate has a first and a second major surface opposite to each other, and a light incidence surface connected with the first and second major surfaces, the light guide plate directing light received at the light incidence surface through the first major surface toward the light modulator. The monochromatic light sources are operable to emit light of different colors in a sequential manner. The optical assembly is arranged adjacent to the light incidence surface of the light guide plate, and is configured to homogenize and distribute the light emitted by each of the monochromatic light sources across the light incidence surface.
