An optical isolation structure is incorporated into a display between the display elements and the transparent substrate for the display elements. The optical isolation structure reflects light rays within the substrate that impact the structure at high angles relative to normal to the structure, thereby permitting the substrate to be used as an integrated light guide for distributing light over the display from a light source on the edge of the substrate. The optical isolation structure may include a single layer having an index of refraction less than the substrate or a plurality of thin-film interference layers.
Une structure d'isolement optique est incorporée dans un écran entre les éléments de l'écran et le substrat transparent d'affichage des éléments. La structure d'isolement optique reflète dans le substrat les rayons lumineux qui la frappent sous des angles élevés par rapport à la normale de la structure, permettant ainsi au substrat de servir de guide de lumière intégré distribuant sur l'écran la lumière d'une source de lumière sur le bord du substrat. Ladite structure peut comporter une seule couche d'un indice de réfraction inférieur à celui du substrat ou plusieurs couches minces d'interférence.
