Abstract

A display for near-eye, virtual reality and augmented reality applications is disclosed. An input beam (LB0) is reflected in a beam-splitting element (110) towards a reflective liquid crystal panel (140). A polarisation modulating element (120) and a polarisation-dependent beam-shifting element (130) are successively positioned between the splitter and the LC-panel. These produce two beams (LB1, LB2), sequential in time but having orthogonal polarisations and shifted in position, which are incident on the LC-panel. After passing back through the three elements, two image beams (IB1', IB2') having the same polarisation state are produced and are projected onto a target. The beams are shifted in position with respect to each other and the target receives two image frames sequentially in time. Each pixel displayed in one image frame overlaps with the respective pixel in the other. In this way, a higher resolution image can be achieved.
