The inkjet printing technique can be an alternative fabrication route for LCD color filters. The source of luminance non-uniformity of color filters fabricated by inkjet printing technique is described and the methods to minimize this non-uniformity are presented. Both drop volume uniformity of inkjet printhead and the morphology of printed color filter layer are important to achieve the required luminance uniformity. Some practical methods to control the drop volume uniformity were tested and proposed. Morphological control of printed color filter was also studied. Desirable interfacial energy between color filter and black matrix was modeled and tested using both plasma treatment and solution treatment.
