COLOR CORRECTION FOR VIRTUAL IMAGES OF NEAR-EYE DISPLAYS

Abstract:

A near-eye display for conveying virtual images within a real-world view includes a projector arranged to compensate for undesirable color gradients in the virtual images. The projector includes an illuminator with an extended light source having a plurality of cells each containing different color light sources and a partial homogenizer for partially overlapping light from the plurality of cells at an illumination plane of a spatial light modulator. A controller adjusts the color outputs of the cells to provide a color distribution over the illumination plane to compensate for the color gradients within the virtual images.
