invention relates to methods and apparatus useful for making color filters for a liquid crystal display. A multicolored ink pattern is deposited to a substrate (22) while in a deformable state, flattened during the deposition process, and the deformed, more uniform shape of the printed dot (7c) is thereafter retained, preferably by curing during deposition. The transfer layer is preferably formed on a collector roll (20). A plurality of colored ink patterns is then transferred to the collector roll (20), preferably from a single pattern roll (19) having multiple patterns (28a-28d) thereon, to form the multicolor image that will become the color filter. This multicolored image is then transferred to the substrate (22).
L'invention concerne des procédés et un dispositif servant à fabriquer des filtres colorés pour des panneaux d'affichage à cristaux liquides. On dépose un motif d'encre multicolore sur un substrat (22), ledit motif étant dans un état déformable et aplati pendant l'opération de dépôt; on conserve ensuite la forme déformée et plus uniforme du point imprimé (7c), de préférence par durcissement pendant le dépôt. La couche de transfert est, de préférence, constituée sur un rouleau collecteur (20). Une pluralité de motifs d'encre colorée sont ensuite transférés au rouleau à motifs uniques (19) pourvu de motifs multiples (28a-28d) de façon à réaliser l'image multicolore qui deviendra le filtre coloré. Cette image multicolore est ensuite transférée vers le substrat (22).
