Abstract
Aspects of the present disclosure relate to optical systems with wide fields of view for use in head-worn computing systems. One aspect relates to a head-worn computer with improved color rendition including an image source with an array of pixels, comprising subpixels, emitting a white light associated with digital content of a displayed image and a color filter array, wherein a color filter is associated with each subpixel to provide a colored image light from each subpixel and a lens for displaying an image within a field of view, comprising colored image light from the subpixels, wherein the lens samples the colored image light from each subpixel to provide the displayed image, and wherein a chief ray angle is associated with the light emitted by each subpixel as sampled by the lens. The color filters are shifted relative to the associated subpixels in correspondence to the chief ray angles.
