Abstract
The invention provides an optical transmission system and a display device, the optical transmission system is used for transmitting collimated image light, the angle range of the image light incident to the optical transmission system is divided into a plurality of angle intervals, and the optical transmission system comprises an optical waveguide, a plurality of coupling-in gratings and a plurality of coupling-out gratings which are arranged on the surface of the optical waveguide, the coupling-in gratings and the coupling-out gratings have corresponding relations, and different coupling-in gratings correspond to different coupling-out gratings; wherein each coupling-in grating is used for coupling image light in a corresponding angle interval into the optical waveguide; the optical waveguide is used for totally reflecting the image light coupled into the optical waveguide; and the coupling-out grating is used for coupling the image light coupled by the corresponding coupling-in grating out of the optical waveguide, and different coupling-in gratings correspond to different angle intervals. According to the technical scheme, the brightness uniformity in the whole view field range can be improved, and the visual watching experience of a user is improved.
Description
technical field [0001] The present disclosure relates to the field of optical technology, in particular to an optical transmission system and a display device. Background technique [0002] Augmented Reality (AR) technology is a technology that ingeniously integrates virtual information with the real world. It simulates virtual information such as text, images, 3D models, music, and videos generated by computers and then applies them to the real world. In , the two kinds of information complement each other to achieve "augmentation" of the real world. [0003] The current augmented reality display device is usually composed of an image source and an optical transmission system, and the image light emitted by the image source is transmitted to human eyes through the optical transmission system. In the related art, a diffractive optical waveguide plate is used as the main structure of the optical transmission system, and the brightness uniformity of the finally displayed imag...
