Abstract

Un dispositif de génération d’image (4) comprend une source de lumière (12), un écran (14) et un dispositif de refroidissement (3). La source de lumière (12) est agencée de manière à éclairer une face avant de l’écran (14) et l’écran (14) comprend une matrice (22) constituée d’éléments dont la transmittance varie de façon contrôlée dans le temps. Le dispositif de refroidissement (3) comprend un évaporateur (32) relié fluidiquement à un condenseur (34) par l’intermédiaire d’un premier conduit et d’un second conduit, de sorte à former une boucle fermée dans laquelle circule un fluide diphasique. L’évaporateur (32) est agencé pour évacuer la chaleur générée par l’écran (14) en s’étendant sur une partie au moins de la périphérie de l’écran (14). (Figure 3)
