High luminance display devices, typically utilized in applications requiring sunlight readability, require unique design methodologies as the thickness approaches a maximum of one-inch. The present invention relates to a high intensity light generation engine (20, 920) and associated light transmission apparatus (30, 42, 40) for transmitting the light generated by the engine to a remote location. The invention is especially applicable for use in constructing a back lighted display (80), such as a liquid crystal display (LCD), of minimal thickness, i.e., one-inch or less. A display (80) of minimal thickness is achieved by separating the light source (12) and other peripherals (from the display device (80), using a remote enclosure (900)). Such a display (80) is most suited for use in high ambient lighting conditions where space is at a premium, such as in the cockpit of an aircraft.

Les dispositifs d'affichage à forte luminance, généralement utilisés dans des applications nécessitant une lisibilité en pleine lumière du jour, nécessitent des méthodologies de conception uniques lorsque leur épaisseur est proche d'une valeur maximale de un pouce. La présente invention concerne un moteur de génération de lumière haute densité (20, 920) et un appareil de transmission de lumière associé (30, 42, 40) pour transmettre la lumière générée par le moteur à un emplacement éloigné. L'invention s'applique particulièrement à la construction d'un affichage à lumière de contre-jour (80) tel qu'un affichage à cristaux liquides d'épaisseur minimale, c'est-à-dire d'un pouce ou moins. Un affichage (80) d'épaisseur minimale est réalisé en séparant la source lumineuse (12) et d'autres périphériques (du dispositif d'affichage (80), à l'aide d'une enceinte éloignée (900). Un dispositif d'affichage de ce type (80) convient parfaitement aux conditions d'éclairage ambiant important, où l'espace est restreint tel que dans le poste de pilotage d'un avion.
