Abstract
A transparent display apparatus. The apparatus includes a transparent display and a prism. The prism includes a polarizing beam splitter for splitting a received light into a first polarized light component and a second polarized light component.

In addition, the prism includes an optical rotator for converting the second light component to a first light component. The converted first light component is transmitted through the prism and displayed through the transparent display. In one embodiment, one or more custom prisms are used. In another embodiment, one or more cube prisms are used.
