Title (EN) HIGH DYNAMIC RANGE DISPLAY DEVICES
(FR) DISPOSITIFS D'AFFICHAGE A PLAGE DYNAMIQUE ELEVEE
Abstract: front page image
(EN)A display has a screen which incorporates a light modulator. The screen may be a front projection screen or a rear-projection screen. The screen is illuminated with light from a light source comprising an array of controllable light-emitters. The controllable-emitters and elements of the light modulator may be controlled to adjust the intensity of light emanating from corresponding areas on the screen. The display may provide a high dynamic range.
(FR)L'invention porte sur un affichage doté d'un écran qui comprend un modulateur de lumière. Cet écran peut consister en un écran à projection avant ou en un écran à projection arrière. L'écran est éclairé par de la lumière issue d'une source de lumière comportant une gamme d'émetteurs de lumière contrôlables. Les émetteurs contrôlables et les éléments du modulateur de lumière peuvent être contrôlés de manière à régler l'intensité de la lumière provenant des zones correspondantes de l'écran. Ledit affichage peut fournir une plage dynamique élevée.
