AI Technical Summary
Technical Problem
Dual-optical-engine solutions increase the size and weight of display devices, reducing the wearing experience.
Method used
A single-optical binocular diffractive waveguide is used. By symmetrically distributing the left and right exit pupil regions on the waveguide substrate, setting up a coupling grating and multiple coupling gratings, and setting a deflection grating in the right exit pupil region, the rational transmission and distribution of light can be achieved.
Benefits of technology
It achieves single-optical binocular display, reduces device size and weight, improves wearing experience, increases diffraction efficiency and eye brightness in the coupling area, and reduces the appearance of dark stripes.

Abstract
The application relates to the technical field of waveguide display, in particular to a single-light-machine binocular diffractive light waveguide and display equipment, which comprises a waveguide substrate, an in-coupling grating, an out-coupling grating and a turning grating. The waveguide substrate is symmetrically provided with a left exit pupil area and a right exit pupil area; the in-coupling grating is arranged in the left exit pupil area; the out-coupling grating is arranged in at least two groups, one group of the out-coupling gratings is arranged in the left exit pupil area, and the other group of the out-coupling gratings is arranged in the right exit pupil area; the turning grating is arranged in the right exit pupil area and is arranged above the out-coupling grating; after incident light is coupled into the waveguide substrate through the in-coupling grating, the incident light can be transmitted to the turning grating and the out-coupling grating in the left exit pupil area. The application has the effect of improving the wearing experience of the display equipment.
