ABSTRACT:
A color filter for an AMLCD panel has a pattern of multi-color dots, each dot having red, green, and blue components in a black matrix. Each component is the cured product of a color pigment dispersed in a radiation-curable ink. The ink may be an ink curable by a cationic mechanism, a free-radical ink, or a hybrid, free-radical/cationic ink. The filter is produced by successively applying patterns of colored inks to a transfer roll, collecting the patterns on a collector roll to form an array of multi-color dots that is transferred to the substrate, and irradiating the array of dots to at least partially cure the inks.
