Abstract
An eyepiece waveguide includes a set of waveguide layers having a world side and a user side. The eyepiece waveguide also includes a first cover plate having a first optical power and disposed adjacent the world side of the set of waveguide layers and a second cover plate having a second optical power and disposed adjacent the user side of the set of waveguide layers.
Claims17
An eyepiece waveguide comprising:
- a set of waveguide layers having a world side and a user side;
- a first cover plate including a first region having a first optical power and a first planar region laterally adjacent to the first region, and disposed adjacent the world side of the set of waveguide layers, wherein the first planar region is positioned outside the user's viewing area;
- and
- a second cover plate having a second optical power and disposed adjacent the user side of the set of waveguide layers, wherein the first optical power and second optical power have different values with respect to each other.
