Publication number: 20220214487Abstract: An optical element includes a waveguide substrate, first and second optical film structures, and a sub-wavelength nanostructure. The waveguide substrate has first and second sides, a light entering surface and a light exiting surface. An image beam can enter the interior of the waveguide substrate through the light entering surface and travel in a manner of total internal reflection. The image beam exits the waveguide substrate via the light exiting surface after one or more reflections. The first and second optical film structures are respectively arranged on the first and second sides. The sub-wavelength nanostructure arranged on the first side can receive and diffract the image beam to couple the image beam to the waveguide substrate. The first and second optical film structures can reflect the part of the image beam at the incident angle smaller than the critical angle of the waveguide substrate.Type: ApplicationFiled: March 24, 2022Publication date: July 7, 2022Inventors: Kuo-Feng LIN, Hui-Wen LU, Wei-Chen LIN, Hui-Ching HSUEH
