Abstract: The invention discloses a near-eye display module based on pixel-block-aperture structures, which includes more than one pixel-block-aperture structures. The divergence angle and propagation direction of the light beam from a pixel is specially modulated, and the light beams from pixels of adjacent pixel-block-aperture structures are endowed with different orthogonal characteristics, to guarantee the light beam from a pixel transmitting to the viewer's pupil only through corresponding aperture(s) for Maxwellian View or one-pupil-multi-view display. The arrangement of multiple pixel-block-aperture structures makes a large field of view (FOV) realizable, and the orthogonal-characteristics design can suppress the crosstalk between adjacent pixel-block-aperture structures effectively.
