Patent ID: 10274731

Abstract:
According to one aspect, the subject matter described herein includes a near-eye optical see-through display. The display includes a backlight layer including a plurality of point light sources. The display further includes a spatial light modulator (SLM) layer for modulating light from the point light sources. The spatial light modulator is located in the optical path between the point light sources and a user's eye. The spatial light modulator layer includes pixels that are controllable to modulate light from the point light sources such that the light that impacts the user's eye has a desired intensity and color to display a synthetic image. At least a portion of the backlight layer and the spatial light modulator layer are optically transparent to allow a user to view a real scene through the spatial light modulator layer and the backlight layer such that the synthetic image appears to be overlaid on a view of the real scene. Each pixel in the spatial light modulator layer modulates only a portion of the light emanating from the point light sources such that the synthetic image appears to be in focus to the user's eye.
