Abstract

The present invention provides a method for producing augmented reality grating waveguides in batches, the method comprising: preparing an embossing master with a preset pattern; coating the embossing glue on the embossing master, and applying The grating waveguide pattern is transferred to the soft film substrate to obtain the soft film with the grating waveguide pattern; the soft film with the grating waveguide pattern is directly pasted on the waveguide substrate to obtain the augmented reality grating waveguide. The present invention reduces two nano-imprints to one nano-imprint, so that the production efficiency of a single-chip grating waveguide is improved, and it is convenient for rapid batch production; It is a flexible material, so that the soft film or embossing glue with the grating waveguide pattern can be pasted on the flat waveguide substrate or on the curved surface, so as to obtain various grating waveguides with different curvatures, and it is easier to obtain conformity Ergonomic grating waveguide.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for mass-producing augmented reality grating waveguides. Background technique [0002] Augmented reality is a technology that organically integrates the images of the virtual world and the scenes of the real world, and has extremely broad application scenarios. Augmented reality needs to see both the real external world and virtual information, so the imaging system cannot block the line of sight, so it is necessary to add one or a group of optical combiners to combine virtual information and real information in the form of "stacking". Scenes blend together, complement each other, and reinforce each other. Grating waveguide is an augmented reality display solution. This technology breaks through the shackles of traditional optics through the optical diffraction effect, and can be extremely thin and light. [0003] At present, grating waveguides can be prepared in batc...
