Abstract
An instrument display includes a light source that selectively emits light and a light guide that receives the light. One or more optical coating layers are disposed on the light guide. The light guide has a first index of refraction, and the optical coating layer or layers have a second index of refraction that is greater than the first index of refraction of the light guide. The optical coating layer or layers reduce glare from ambient light and increase the light transmitting performance of the light guide.
