Abstract
A heads-up display includes a windshield with a standardized wedge profile and an embedded reflective polarizer and a display. The reflective polarizer is disposed between, and spaced apart from, opposing outermost first and second major glass surfaces of the windshield. The heads-up display forms a virtual image for viewing by the eye of a passenger. An image emitted by the display may include a first image ray emitted from a predetermined region of the display and incident on the outermost first major glass surface of the windshield at an angle of incidence greater than about 60 degrees, with at least 90% of the incident first emitted image ray polarized in a plane of incidence of the first emitted image ray.
