Title (EN) METHOD AND DEVICE FOR MANUFACTURING COLOR FILTER
(FR) PROCEDE ET DISPOSITIF POUR LA FABRICATION D'UN FILTRE EN COULEURS
Abstract:
(EN) A method of manufacturing a color filter having a transparent electrode (3) on a transparent substrate (2), and a colored layer formed on the electrode and capable of transmitting light in a specific wavelength region. This manufacturing method comprises the steps of bringing the transparent electrode (3) into contact with a film-forming solution (1) of an electrolyte with dispersed pigment particles; and applying a voltage to electrolyze the solution (1) between the electrode (3) and a submerged electrode (4) so that a colored layer may be formed on the transparent electrodes (3). The contact of the electrode (3) with the solution (3) may be achieved by placing the electrode (3) into or onto the solution (1).
(FR) L'invention concerne un procédé pour la fabrication d'un filtre en couleurs, qui consiste à utiliser une électrode transparente (3) sur un substrat transparent (2), et à former sur l'électrode une couche de couleurs capable de transmettre la lumière dans une gamme de longueurs d'ondes spécifique. Ce procédé comprend les opérations suivantes: mettre l'électrode transparente (3) au contact d'une solution filmogène (1) d'électrolyte à base de particules de pigments dispersés; appliquer une tension, pour l'électrolyse de la solution (1), entre l'électrode (3) et une électrode immergée (4), de manière à pouvoir former une couche de couleur sur l'électrode transparente (3). On peut établir le contact entre l'électrode (3) et la solution (3) en plaçant l'électrode (3) dans la solution (1) ou sur la solution (1).
