  • Illuminants are arranged laterally on narrow sides of the light guide, preferably on one or both long sides of the light guide,
  • the decoupling elements have maximum dimensions of " ⁇ ⁇ , preferably between 1 ⁇ and 15 ⁇ , on.
  • means for Reflex reduction or control for example, a Antiglare- and / or an antireflection coating, be arranged.
  • the decoupling elements 6 have maximum dimensions of 100 ⁇ , preferably between 1 ⁇ and 15 ⁇ on. Typically, the decoupling elements 6 vary in number per area over the surface of the light guide 3 in order to achieve the desired decoupling properties, such as the output characteristics of the decoupling elements.

Abstract

La présente invention concerne un écran (1) que l'on peut faire fonctionner dans au moins deux modes de fonctionnement B1 pour un mode visualisation dégagée et B2 pour un mode visualisation restreinte, l'écran comprenant un rétroéclairage (2) plan qui émet de la lumière sur un secteur angulaire restreint ; un dispositif de production d'image (5) transmettant la lumière, disposé en amont du rétroéclairage (2) dans le sens d'observation ; un guide d'onde optique (3) plat qui est disposé entre le dispositif de production d'image (5) et le rétroéclairage (2), qui se compose d'une matière thermoplastique ou thermoélastique transparente et qui présente sur au moins l'une des surfaces majeures et/ou à l'intérieur de son volume des éléments de sortie (6), des moyens d'éclairage (4) étant disposés latéralement sur les côtés étroits du guide d'onde optique (3), le guide d'onde optique (3) étant transparent à au moins 70 % à la lumière qui sort du rétroéclairage (2), le nombre par unité de surface et la dimension des éléments de sortie (6) étant sélectionnés de sorte que le guide d'onde optique (3) présente sur au moins 80% de sa surface une valeur de trouble moyenne inférieure à 7%, ce qui permet à la lumière émise par le rétroéclairage (2) au moins dans le mode de fonctionnement B2 sur un secteur angulaire restreint, d'être juste légèrement diffusée lors du passage par le guide d'onde optique (3), les éléments de sortie (6) étant par ailleurs répartis sur au moins l'une des surfaces majeures et/ou à l'intérieur du volume du guide d'onde optique (3) de sorte que la sortie de la lumière provenant des moyens d'éclairage (4), hors du guide d'onde optique s'effectue à au moins 80 % sur l'une des surfaces majeures du guide d'onde optique (3) en direction du dispositif de production d'image (5), et le mode de fonctionnement B2 s'accompagnant de l'allumage du rétroéclairage (2) et de l'arrêt des moyens d'éclairage (4), et le mode de fonctionnement B1 s'accompagnant de l'allumage au moins des moyens d'éclairage (4).
