摘要

Inkjet printing technology has been applied to the fabrication of monochrome color filter films and has afforded an efficient and economic production process for flat panel displays. We demonstrate the preparation and physical characterization of the red and/or green monochrome films on glass substrates by inkjet printing technology with pigment-based colorant resist inks. For the green films, a thickness of 1.45 μm and the color coordinate value of x=0.309, y=0.588 and the brightness of Y=58.90 in CIE 1931 diagram are attained at the optimal ink amounts of 1400 pl for green droplets. For the red colorant films, an appropriate film thickness of 1.20 μm and the coordinate value of x=0.572, y=0320 and the brightness of Y=27.1 in chromaticity diagram at the red droplets amounts of 900 pl are obtained. The experimental results exhibit the percentages of optical transmittance of the as-printed green films achieve greater than 85.0% in the spectral range of 515.0 nm and those of the as-printed red films in the subpixel cell can achieve 98.0% in the range of 640.0 nm.
