Abstract
L'invention concerne un dispositif d'affichage (10) comprenant : - un écran (13) présentant une transmission optique commandable, et - un premier ensemble de rétro-éclairage (11) configuré pour émettre vers l'écran un premier rayonnement lumineux de manière à éclairer, après transmission par l'écran, un premier champ d'éclairage. Selon l'invention, le dispositif d'affichage comprend un deuxième ensemble de rétro-éclairage (12), situé entre l'écran et le premier dispositif de rétro-éclairage, qui comporte : - un guide de lumière réalisé au moyen d'une plaque (122) au moins partiellement transparente, et - une deuxième source de lumière (112) disposée en périphérie de la plaque, le guide de lumière étant configuré pour qu'un deuxième rayonnement lumineux reçu de la deuxième source de lumière sorte au moins en partie de ladite plaque en direction de l'écran pour éclairer, après traversée de l'écran, un deuxième champ d'éclairage au moins partiellement disjoint du premier champ d'éclairage.The invention relates to a display device (10) comprising: - a screen (13) having a controllable optical transmission, and - a first backlight assembly (11) configured to emit towards the screen a first light radiation of so as to illuminate, after transmission by the screen, a first lighting field. According to the invention, the display device comprises a second backlight assembly (12), located between the screen and the first backlight device, which comprises: - a light guide produced by means of a plate (122) at least partially transparent, and - a second light source (112) disposed at the periphery of the plate, the light guide being configured so that a second light radiation received from the second light source exits at least in part of said plate in the direction of the screen to illuminate, after passing through the screen, a second illumination field at least partially separate from the first illumination field.
