Display system

Abstract:

An apparatus for image viewing and eye tracking in virtual or mixed reality systems that includes two or more display panels (e.g., a top display panel and a bottom display panel) for each eye with left and right prisms located between the display panels and the user's eyes. S- and P-polarizing filters are located between the display panels and first and second surfaces of the prism. For each eye, the polarized light from the top and bottom display panels is redirected by a respective prism to form exit pupils for top and bottom images at a plane at or near the eye. At least one eye-tracking camera is located in front of each prism and between the top and bottom display panels so that the cameras have a direct or near-direct view of the user's eyes through the eyepieces.
