Abstract:
A see-through display including a polarized reflective pinhole mirror display. The pinhole mirror display includes a plurality of tiny switchable polarized mirrors. The respective polarized mirrors individually reflect impinging light from an illuminator, and guide the respective portion of light into a pupil of an eye. A reflective optically powered surface reflects light from the illuminator. Each mirror has a first polarization and reflects a portion of light and produces a picture element (pixel) that forms a virtual image seen by the eye of the user. A user may view the reflected virtual image having the first polarization from the illuminator, as well as the image from the real world via a rear substrate that has a second polarization. Although the mirrors are very small, human eyes can still detect the mirrors if they are not polarized. The mirrors and other components are polarized so that the eye can see the real world filtered with the second polarization, but not the mirrors having a different first polarization.
