1. A near-eye display module based on pixel-block-aperture structures, comprising:
M pixel-block-aperture structures, each of which being constructed by mutually corresponded a pixel block, an aperture, a modulation component, an orthogonality generating component and an orthogonality detecting component, wherein a positive integer M≥2;
wherein, the pixel block is composed of pixels for optical information loading, and a pixel array is composed of the pixels of all pixel blocks of the M pixel-block-aperture structures; an aperture array is composed of all apertures of M pixel-block-aperture structures on an aperture surface; the modulation component is composed of modulation elements, which correspond to pixels of a corresponding pixel block in a one-to-one manner, to guide the light beam from a pixel to a corresponding aperture with a confined diverging angle; the orthogonality detecting component is attached to a corresponding aperture, for only allowing light of corresponding orthogonal characteristic passable, but blocking light of other non-corresponding orthogonal characteristic; the orthogonality generating component of each block-aperture structures is attached to a corresponding pixel block, endowing pass-through light with orthogonal characteristic same to that of a corresponding orthogonality detecting component;
a control device, which loads optical information onto a pixel at a time-point, with the optical information being the projecting information of a 3D scene to be displayed at the time-point along a line connecting the pixel and its corresponding aperture;
said near-eye display module based on pixel-block-aperture structures is configured that the N orthogonality detecting components of adjacent N pixel-block-aperture structures are with N kinds of orthogonal characteristics respectively, with the apertures attached by the orthogonality generating components of a same orthogonal characteristic taken as apertures of a same kind, wherein an integer M≥N≥2, and the light beam from a pixel is modulated by a corresponding modulation element, to guarantee its light distribution covers the corresponding aperture, but misses the non-corresponding apertures of the same kind.
