Abstract
A sunglasses-style head worn display includes a curved waveguide with double reflective coatings/films and containing an array of light wavelength converting phosphor pinhole-size discs covered with pinhole-sized micro lenses, presenting a wide FOV virtual image for AR/VR.
Claims21
An assembly, comprising:
- a curved waveguide;
- a first ultraviolet (UV)-light-reflecting coatings and/or films disposed on the waveguide;
- a second UV light-reflecting coatings and/or films disposed on the waveguide;
- at least one UV emitter configured to emit UV light into the waveguide between the first and second UV light-reflecting coatings and/or films;
- and
- at least one conversion element in the waveguide and disposed to receive UV light from the UV emitter, the conversion element being configured to convert UV light into visible light that propagates through one or both UV light-reflecting coatings and/or films and that impinges on the eye of a wearer of the waveguide.

An apparatus, comprising:at least one curved waveguide configured to be worn on the head of a person and defining an infrared (IR) light passageway in which IR light is constrained from passing through;
- at least one IR emitter optically coupled to the light passageway to emit demanded virtual reality (VR) and/or augmented reality (AR) images into the light passageway;
- and
- at least one conversion element in the light passageway to receive IR light from the IR emitter, the conversion element being configured to convert IR light into visible light that propagates out of the light passageway to impinge on an eye of the person when the person is wearing the waveguide.
An apparatus, comprising:
- at least one curved waveguide configured to be worn on the head of a person and defining an ultraviolet (UV) or infrared (IR) light passageway in which UV or IR light is constrained from passing through;
- at least one UV or IR emitter optically coupled to the light passageway to emit demanded images into the light passageway;
- and
- at least one UV or IR sensor outside the UV or IR light passageway to generate at least one signal upon detection of UV or IR light, the signal being operable to cause the UV or IR emitter to stop emitting UV or IR light into the light passageway.
