Based on Micro LED technology, the engine is small and light and match with different waveguide glass. The imaging from engine reaches human eyes via waveguide, and meanwhile, the ambinent light also reaches human eyes via waveguide, the overlap of real and virtual imaging can achieve the effect of augmented reality.

Using the principle of geometric reflection, the light is expanded in the transflective array film layer, and the film layer reflects the light into the user's eyes. It's thin and light with clear imaging and good color uniformity.

Using the principle of optical diffraction, the image information emitted by the optical-mechanical end is coupled into the waveguide through the coupling grating, and the relay grating expands and regulates the light to the coupling-out grating, and the coupling-out grating expands the light and is coupled to the user's eyes, so that human eyes can clearly observe the image.
