Abstract
Head-mounted display visor assembly. A head mounted display visor assembly includes a molded world-facing visor coupled to a separately molded user-facing bathtub. The visor includes an IR opaque and visual light opaque portion coupled to a separately manufactured IR permissive portion. The visor also includes an IR opaque portion. The bathtub includes an IR permissive, but visual light opaque portion and a visual light permissive portion.
Claims20
A head mounted display visor assembly comprising:
- a molded visor, the visor comprising:
- an IR opaque region;
- an IR opaque and visual light opaque region at a top of the visor adjacent to, and above the IR opaque region;
- and
- a separately manufactured IR window coupled to the IR opaque and visual light opaque region;
- and
- a separately molded bathtub coupled to the visor, the bathtub comprising:
- an IR permissive, but visual light opaque region at a top of the bathtub;
- and
- a visual light permissive portion adjacent the visual light opaque region.
A method for manufacturing a head mounted display visor assembly, the method comprising:
- obtaining a molded visor composed of a polycarbonate resin and an infrared (IR) absorption dye, wherein the molded visor includes a window frame for receiving a separately manufactured IR window;
- applying a visible light opaque evaporative coating to a top portion of the molded visor to form an IR opaque and visible light opaque region, which is separate from an IR opaque region of the molded visor;
- obtaining a separately molded bathtub composed of a polycarbonate resin which transmits both IR and visible light;
- and
- applying a visible light opaque but IR permissive coating to a top portion of the separately molded bathtub to form an IR permissive, but visible light opaque region, which is separate from a visible light permissive region of the separately molded bathtub.
A method for using a head mounted display visor assembly, the method comprising:
- obtaining a head mounted display including a head mounted display visor assembly, the head mounted display visor assembly comprising:
- a molded visor, the molded visor comprising:
- an IR opaque region;
- an IR opaque and visible light opaque region at a top of the molded visor adjacent to, and above the IR opaque region;
- and
- a separately manufactured IR window coupled to the IR opaque and visible light opaque region;
- and
- a separately molded bathtub coupled to the molded visor, the separately molded bathtub comprising:
- an IR permissive, but visible light opaque region at a top of the separately molded bathtub;
- and
- a visible light permissive region adjacent to the IR permissive, but visible light opaque region;
- and
- displaying one or more holograms on a display of the head mounted display situated between the molded visor and the separately molded bathtub of the head mounted display visor assembly, such that display light from the display transmits through the visible light permissive region of the separately molded bathtub to an eye of a user, and wherein the separately molded bathtub operates as at least part of an optical system of the head mounted display for focusing the one or more holograms at a predefined distance from the head mounted display visor assembly.
