Display apparatus

This invention describes a display system that shows two separate images, each directed to its own viewing screen or lens. Instead of having two completely separate projection systems, it uses a single, central optical system that cleverly guides both images to their respective screens. One version specifically describes the image sources being crossed over, so the first image source sends its picture to the second screen, and vice-versa, all through that shared central optical pathway.

Why it matters: Filed before significant advancements in compact micro-displays and precision optical manufacturing. These improvements could now enable the complex shared optical path for dual images.
