Patent attributes
Systems and apparatus are described for a head-mounted display apparatus comprising at least one optical assembly. Each optical assembly may include a first curved lens including a first surface and a second surface, a second curved lens including a third surface and a fourth surface, the third surface being concave and including a beam splitter layer, the second curved lens being disposed between the first curved lens and an input filter assembly, and a display panel adapted to receive image content from an image projecting device and transmit the image content through the at least one optical assembly. The third surface of the second curved lens may have a radius of curvature that is larger than a radius of curvature of the second surface of the first curved lens.
