Large area color filter fabrication by using ink-jet printing technology

Abstract

A novel ink jet printing process without additional photolithography process for large area color filter fabrication has been developed in this study. A 100x100 mm(2) model of 32" color filters was fabricated for evaluation. New developed RGB inks were able to achieve 73% NTSC standard with the thickness of R, G, and B films at 1.80, 1.90, and 1.80 pm, respectively. The overflow issue can be solved by surface pretreatments, and color inks formulation.
