Thin curved eyepiece for see-through head wearable display
First Claim
1. An eyepiece for a head wearable display, the eyepiece comprising:
- a curved light guide component for guiding display light received at a peripheral location offset from a viewing region and emitting the display light along an eye-ward direction in the viewing region, the curved light guide component including;
an eye-ward facing surface;
a world facing surface; and
a recessed surface that is discontinuous with the world facing surface;
an add-on component having a first surface mated to the recessed surface and a second surface that forms a continuous outer surface with the world facing surface of the light guide component, wherein the eye-ward facing, world facing, recessed, first, second, and outer surfaces are all curved surfaces; and
a partially reflective layer disposed along an interface between the recessed surface and the first surface of the add-on component.

Abstract
An eyepiece for a head wearable display includes a light guide component for guiding display light received at a peripheral location offset from a viewing region and emitting the display light along an eye-ward direction in the viewing region. The light guide component includes an eye-ward facing surface, a world facing surface, and a recess disposed in the world facing surface in the viewing region. The recess has a recessed surface that is discontinuous with the world facing surface. An add-on component is disposed in the recess and has a first surface mated to the recessed surface and a second surface that forms a continuous outer surface with the world facing surface. A partially reflective layer is disposed along an interface between the recessed surface and the first surface of the add-on component.

13. A head wearable display, comprising:
-
a display source to generate display light at a peripheral location; a light guide component for guiding the display light to a viewing region offset from the peripheral location and emitting the display light along an eye-ward direction in the viewing region, the light guide component including; an eye-ward facing surface; a world facing surface; and a recess disposed in the world facing surface in the viewing region, the recess having a recessed surface that is discontinuous with the world facing surface; an add-on component disposed in the recess, the add-on component having a first surface mated to the recessed surface and a second surface that forms a continuous outer surface with the world facing surface of the light guide component, wherein the eye-ward facing, world facing, recessed, first, second, and outer surfaces are all curved surfaces; a partially reflective layer disposed along an interface between the recessed surface and the first surface of the add-on component; and a frame assembly to support the light guide component and the display source for wearing on a head of a user with the viewing region positioned in front of an eye of the user. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
