Abstract
(EN) A reflective display tile (100) can be used in connection with a static or video display. The tile (100) includes a transparent substrate (110) having a front surface (112), a rear surface (114), and a peripheral edge (116) surrounding the front and rear surfaces (112, 114), an electrostatic shutter array (130) disposed at the front surface (112) of said substrate (110), a reflective medium (150) disposed at the rear surface (114) of the substrate (110), and drive electronics (180) disposed rearward of the reflective medium (150). The shutter array (130) and drive electronics (180) are configured so that the tile (100) is tileable and can be abutted at any of its peripheral edges (116) against identical tiles (100) to form a display with substantially no perceived optical interface between adjacent tiles (100). Another embodiment includes an opaque substrate (310) such as a circuit board.
(FR) L'invention concerne un pavé d'affichage réfléchissant (100) pouvant être utilisé en connexion avec un afficheur statique ou vidéo. Le pavé (100) comprend un substrat transparent (110) ayant une surface avant (112), une surface arrière (114) et un bord périphérique (116) entourant les surfaces avant et arrière (112, 114), un réseau d'obturateurs électrostatiques (130) disposé au niveau de la surface avant (112) dudit substrat (110), un support réfléchissant (150) disposé au niveau de la surface arrière (114) du substrat (110), et des composants électroniques d'entraînement (180) disposés à l'arrière du support réfléchissant (150). Le réseau d'obturateurs (130) et les composants électroniques d'entraînement (180) sont conçus de telle sorte que le pavé (100) puisse être incliné et puisse être mis en butée au niveau de l'un quelconque de ses bords périphériques (116) contre des pavés identiques (100) pour former un afficheur n'ayant sensiblement aucune interface optique perçue entre des pavés adjacents (100). Un autre mode de réalisation comprend un substrat opaque (310) tel qu'une carte de circuit imprimé.
