Definitions
- 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. Homogeneity, to achieve.
- a further advantageous embodiment of the invention provides that for the operating mode B1, the light originating from the light sources 4 and emerging from the light guide 3 at each point of its surface in angles ⁇ > 40 ° and / or ⁇ ⁇ -40 ° - preferably even in Angles ß> 20 ° and ß ⁇ -20 ° -, measured perpendicular to the surface of the light guide 3 and in a vertical orientation to the surface of the light guide 3 (with orientation here the orientation of the light guide 3 and thus inherently also the imager 5 is meant, ie in particular a portrait or landscape orientation), at most 50% of the light intensity having the light emerging from such a point of the surface of the light guide 3 perpendicular to its surface. This will e.g. a reduction of disturbing reflections in the windshield, especially when driving at night, achieved when the screen according to the invention is installed in a vehicle.
- a flat radiator preferably a light guide with laterally or on the back arranged Leuchtm itteln, e. LEDs,
- directed backlight 2 ie a "directed backlight” is also possible.
