Abstract
(EN)
An area light source module (10) and a control method therefor, and a display device. The area light source module (10) comprises a light guide plate (100), a light source (200) and a light valve component (300), wherein the light guide plate (100) comprises two main surfaces (110/120) and a side surface located between the two main surfaces (110/120), the side surface comprises an incident side surface (131), the light source (200) and the incident side surface (131) are arranged opposite each other, and the light valve component (300) is located between the light guide plate (100) and the light source (200). The light valve component (300) is configured to control the passing rate of light, from the light source (200), emitted from the incident side surface (131) into the light guide plate (100). The light valve component (300) can control the distribution of light emitted from the light source (200) in the light guide plate (100), thereby improving the dynamic contrast of the area light source module (10).

La présente invention concerne un module de source de lumière de zone (10) et son procédé de commande, et un dispositif d'affichage. Le module de source de lumière de zone (10) comprend une plaque de guidage de lumière (100), une source de lumière (200) et un élément modulateur de lumière (300), la plaque de guidage de lumière (100) comprenant deux surfaces principales (110/120) et une surface latérale située entre les deux surfaces principales (110/120), la surface latérale comprenant une surface latérale incidente (131), la source de lumière (200) et la surface latérale incidente (131) étant disposées en regard l'une de l'autre, et l'élément modulateur de lumière (300) étant situé entre la plaque de guidage de lumière (100) et la source de lumière (200). L'élément modulateur de lumière (300) est configuré pour commander le débit de lumière, à partir de la source de lumière (200), émis à partir de la surface latérale incidente (131) dans la plaque de guidage de lumière (100). L'élément modulateur de lumière (300) peut commander la distribution de la lumière émise par la source de lumière (200) dans la plaque de guidage de lumière (100), améliorant ainsi le contraste dynamique du module de source de lumière de zone (10).
