Abstract

A color filter is the penetrable device adhering red, green, and blue organic color resists onto the surface of glass substrate for application of liquid crystal displays. It is fabricated by several technologies, including lithographic processes of coating, baking, exposing, etching, and rinsing. Inkjet printing technology has potentially implemented on the fabrication of the large-size panel with organic molecular film since this technology offers an efficient and steady production procedure. To achieve the basic specifications and requirements of high color performance, high color purity, high flatten, low reflective, and low production cost, inkjet printing technology will be seriously considered in the color filter manufacturing. Here we present the experimental results on physical and chromatic characteristics of color filters by implementing inkjet printing technology. To verify the chromatic characteristics of the resultant color filters, CIE 1931 chromaticity diagram is adopted to present the coordination of color distribution. For the green color ink, the results are x=0.3095±0.04, y=0.5912±0.04, brightness of Y=58.887 for 50 droplets and x=0.3103±0.04, y=0.5784±0.04, brightness of Y=60.328 for 41 droplets. For the blue color ink, the result is x=0.1490±0.04, y=0.1015±0.04, brightness of Y=8.808. For the red color ink, the result is x=0.572±0.04, y=0.320±0.04, brightness of Y=27.1.
