- Abstract
- The transmittance and color characteristics of color filters are directly related to the energy efficiency and image quality of LCD panels. We tried to investigate the effect of fluorescent dyes, (Z)-3-(4 '-(dimethylamino)biphenyl-4-yl)-2-phenylacrylonitrile, on the transmittance and the color gamut of LCD panel. The fluorescent dye was synthesized and dispersed in polymer matrix and implemented at the lamp side before the color filters. Energy transfer from blue to green using fluorescent dye 1 can be applied to increase energy efficiency of green color resist. The fluorescent films using dye 1 can improve the transmittance about 4-5% and the color gamut and color purity that can be inferred from the color coordinate change from (X = 0.309, Y = 0.467) to (X = 0.325, Y = 0.521).
