Abstract
The present invention generally relates to a scheme for making color filters on the basis of laser printing, and particularly to a scheme exploiting digital systems (or logic processor) and laser printer to make color filters in a simple, economical, and swift way, and being capable of dynamically adapting to various demanded specifications. The scheme for making color filters according to the present invention mainly comprises the steps: defining a dot matrix according to the demanded specifications; converting the dot matrix into an image signal; and executing a laser printing process to print, according to the image signal, an image of the dot matrix on a transparent plate.
