Abstract

The invention provides retina light field display MR glasses capable of accelerating transmission of a digital pupil signal. A monocular/binocular depth shooting module is used to collect an MR data stream, a graphic image signal is generated, an image accelerated processor processes data of the graphic image signal to obtain a binary data stream, and a high-speed digital micro lens encodes and reflects/refracts the binary data stream to obtain the exit pupil. The exit pupil is refracted by a digital grating array in a binocular near-eye refraction light path and finally projected to the retina. Thus, the graphic picture signal is processed in the accelerated way, and then the high-speed digital micro lens can complete electric to optical signal conversion more timely, the data refresh rate is improved, and frames seen by the eyes feel less granular, and further, a deep digital grating in the digital grating array refracts the depth of the light signal, image projection is changed intodepth projection, and the user experience is enhanced.

Description

technical field [0001] The invention relates to the field of mixed reality display, in particular to retinal light field display MR mixed reality glasses that can accelerate digital pupil signal transmission. Background technique [0002] In the prior art, LED, LCD, and OLED screens are commonly used in mixed reality near-eye imaging technology based on liquid crystal on silicon. The light guide system applied in the near-eye display terminal is used to project images onto the near-eye display screen in the near-eye display terminal. In order to further provide an immersive look and feel, the 4:3 or 16:9 picture is usually magnified through the lens and then projected directly. Since the pixels are directly magnified and projected, the picture is grainy to the eye and the picture is not good. The sand window effect is obvious . [0003] There is also a huge amount of mixed reality image data, and the main calculation is concentrated in computer vision. Therefore, even if t...
