Abstract
A head-mounted display device for providing augmented reality contents to a wearer includes a light projector and a pancake combiner. The light projector is configured to project a light having a first polarization for rendering images based at least on the augmented reality contents. The pancake combiner is configured to combine the light from the light projector and light from an outside of the head-mounted display device for providing an overlap of the rendered image and a real image that corresponds to the light from the outside of the head-mounted display device. The pancake combiner is also configured to direct the light from the light projector toward a pupil of an eye the wearer.
