1. A display system comprising:
- a waveguide disposed at least partially above a top surface of a glare shield, the waveguide being configured as a combiner to allow viewing of an outside scene and first information from an image source, wherein the waveguide comprises at least a first portion of a first surface for viewing the outside scene and the first information by a user, wherein the waveguide is configured to be disposed such that the first surface is between the user and a windshield; and
a head down display disposed below the top surface of the glare shield, wherein the first surface of the waveguide comprises a bottom edge, the bottom edge extending below the top surface of the glare shield and wherein at least a second portion of the first surface is between a second surface of the head down display and the user, wherein the second surface is for providing second information from the head down display to the user, wherein the first surface of the waveguide is a continuous viewing surface between a top edge of the waveguide and the bottom edge of the waveguide, wherein the top edge of the waveguide is in front of a portion of the windshield through which the outside scene is viewable, and a top of the continuous viewing surface is in front of the portion of the windshield through which the outside scene is viewable and a bottom of the continuous viewing surface is in front of or below the head down display.
