Title (EN) SELECTIVE DISPLAY DEVICE FOR A PLURALITY OF INFORMATIONS
(FR) DISPOSITIF D'AFFICHE SELECTIF D'UNE PLURALITE D'INFORMATIONS
Abstract: front page image
(EN)A display device comprising a transparent window (1), a base plate (5) and two superposed insulating intermediary plates (18a, 18b) interposed between the window and the base plate, said intermediary plates having openings so as to define a plurality of transverse openings (19) extending without any obstacle from the base plate (5) to the window (1). Inside the openings (19), a plurality of movable electrodes (10) extending between the intermediary plates (18a, 18b) are embedded by at least one of their ends (21) and connected outside the housing (16) by connection tracks (22l to 22x) The internal sides of the window (1) and of the base plate (5) are each further provided with a network of fixed electrodes (31 to 3n; 61 to 6n), protected by a single insulating layer (4, 7), the housing (16) being filled with a non polar opaque liquid of high electric resistivity. The movable electrodes (10) may be deflected selectively electrostatically between two stable positions (10a, 10b) for which they come respectively to bear against the window (1) and against the plate (5), hence the electrodes (10) being, respectively, visible through said window or occulted by the opaque liquid. Manufacturing process of said display device.
(FR)Dispositif d'affichage comprenant une fenetre transparente (1), une plaque de base (5) et deux plaques intermediaires isolantes superposees (18a, 18b) interposees entre la fenetre et la plaque de base, ces plaques intermediaires etant ajourees de facon a delimiter une pluralite de jours transversaux (19) s'etendant sans entraves de la plaque (5) a la fenetre (1). A l'interieur des jours (19) s'etendent une pluralite d'electrodes mobiles (10), encastrees par au moins une de leurs extremites (21) entre les plaques intermediaires (18a, 18b) et reliees a l'exterieur de l'enceinte (16) par des pistes de connexion (22l a 22x). Les faces internes de la fenetre (1) et de la plaque de base (5) sont en outre pourvues chacune d'un reseau d'electrodes fixes (3l a 3n; 6l a 6n), protege par une couche isolante unique (4, 7), l'enceinte (16) etant remplie d'un liquide opaque non polaire a haute resistivite electrique. Les electrodes mobiles (10) peuvent etre deflechies selectivement electrostatiquement entre deux positions stables (10a, 10b) pour lesquelles elles viennent respectivement se plaquer contre la fenetre (1) et contre la plaque (5), les electrodes (10) etant ainsi, respectivement, visibles au travers de cette fenetre, ou occultees parle liquide opaque. Procede de fabrication dudit dispositif d'affichage.
