Abstract
An augmented reality display device includes a display, a polarizing beam splitter, and a reflective liquid crystal panel. The display is configured to provide an image beam. The polarizing beam splitter is disposed on a path of the image beam. The reflective liquid crystal panel is disposed on a path of the image beam from the polarizing beam splitter. The reflective liquid crystal panel is configured to form a plurality of modulating and reflecting regions separate from each other. The modulating and reflecting regions are configured to modulate a polarized direction of the image beam and reflect the image beam back to the polarizing beam splitter. The polarizing beam splitter is configured to make the modulated image beam travel to an eye of the user. The reflective liquid crystal panel is configured to vary a pitch of the modulating and reflecting regions.
