Title: Dynamic focusing head mounted display
IPC: G02B27/02
Filed: 2022-09-06
Abstract: PROBLEM TO BE SOLVED: To solve such a problem that, if the user looks at an object that appears closer than a virtual image, accommodation by the user's eyes will cause the virtual image to appear blurry in a conventional head-mounted display (HMD) which can display a virtual image at a fixed focus (e.g., infinite focus). 
     SOLUTION: The HMDs disclosed herein include a dynamic electro-active focusing element that changes the focus of a virtual image to account for accommodation by the user's eyes. This dynamic electro-active focusing element may include a curved layer of electro-active material, such as nematic or bi-stable (e.g., cholesteric) liquid crystal, disposed between a static concave mirror and a convex surface on a beam splitter or other optical element. Changing the refractive index of the electro-active material causes the focus of the dynamic electro-active focusing element, making it possible to shift the virtual image's focus in as the user's eyes change focus.
