It has always been a hot topic to break the angular resolution/field-of-view (FOV) invariant and achieve a near-eye display with a large FOV and high-resolution. We present a super-resolution method for near-eye displays by overlapping images from two display panels using a half mirror. Key aspects including theoretical analysis, optimized method, system set-up, and calibration process are discussed detailly. A proof-of-concept prototype was developed to provide a super-resolution image capable of significantly higher sampling rate.
