Wearable heads-up displays including combiner with visual artifact reduction

Abstract

A wearable heads-up display (WHUD) reduces the prevalence of visual artifacts by employing a projector with a combiner including a plurality of combiner elements such as dichroic prisms. The projector is configured with one or more features that 1) reduce the amount of stray light generated at the combiner 2) change the path of the stray light so that the stray light is unable to exit the projector and thus is unable to create visual artifacts, or any combination thereof. By reducing the stray light that is generated and by changing the path of the stray light as described herein, the likelihood that a user will see a visual artifact is reduced, thus improving the user experience with the WHUD system.
