- Abstract
- Color filters (CFs) are important elements for making color images in liquid crystal displays (LCDs) and other imaging devices. A colored layer is fabricated with colorants of red, green, and blue from either dyes or pigments. These colorants are arranged uniformly and make up the CF while also converting white backlight into a color image. The pigment is advanced to thermal stability, light resistance and chemical resistance, so many used for manufacturing color filters. However, the color filters manufactured with pigments have spectral drawbacks such as decreased transmittance of light and decreased contrast ratio both caused by aggregation of pigment particles. Thus, it is necessary to do the expensive and time-consuming dispersion process for obtaining stable and finer pigment millbases without molecular aggregation. In this study, our focus was on a new series of acid dye systems that have alkyl amine groups because it has an advantage in solubility of organic solvents. As a result of our focus, we have designed and synthesized new acid dyes that consist of alkyl amine groups, using a simple method of reaction. In addition, manufacturing color filters without the milling process in the optical characteristics, thermal, chemical stability were investigated.
