Title (EN) THIN INSTRUMENT CLUSTER WITH ANTI-REFLECTIVE COATING
(FR) GROUPE D'INSTRUMENTS MINCE A REVETEMENT ANTIREFLET
Abstract:
(EN) An instrument display includes a light source (20) that selectively emits light and a light guide (24) that receives the light. One or more optical coating layers (42) 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.
(FR) La présente invention a trait à un affichage d'instruments comportant une source lumineuse qui assure l'émission sélective de la lumière et un guide de lumière qui reçoit la lumière. Une ou des couches de revêtement optique sont disposées sur le guide de lumière. Le guide de lumière présente un premier indice de réfraction, et la/les couche(s) présente(nt) un deuxième indice de réfraction qui est supérieur au premier indice de réfraction du guide de lumière. La couche de revêtement optique réduit l'éblouissement provenant de la lumière ambiante et accroît la capacité de transmission de lumière du guide de lumière.
