A 7 inch plastic QVGA color filter fabricated by all-inkjet printing

Abstract

This article describes how to fabricate a 7 inch QVGA high saturation color filter panel by all-inkjet printing technique. Besides printing the red, green and blue color resists, we fabricate the fine stripe-type trenches for ink confining in a high throughput printing method. The color saturation of the resulting printed color filter can reach to 67.8% of NTSC.
