Description
Technical Field
The invention relates to the LCD liquid crystal industry, in particular to a pigment synergist and a preparation method thereof, a photoresist composition and an optical filter.
Background
In the field of flat panel displays, TFT-LCD (thin film transistor liquid crystal display) is the mainstream of the market, and Color Filter (CF) is one of the most important main materials of LCD and OLED, so that the liquid crystal display realizes colorization, which directly determines the quality of Color images of the display. The color photoresist and the black photoresist are core materials for preparing the color filter, account for about 27% of the cost of the color filter, and the color paste is an important material for preparing the photoresist.
The color layer of the color filter mainly comprises red, green and blue, the red, green and blue pixels are manufactured by using color photoresist, the preparation of the color photoresist comprises two parts, firstly, color paste is prepared by using pigment, and then, the color paste is used for preparing the photoresist, and the color paste mainly comprises pigment, auxiliary agent, solvent and the like; the photoresist comprises color paste, light-cured resin, photoinitiator and the like. The quality of the color filter mainly depends on the performance of the pigment photoresistor and the coating process thereof, wherein the photoresistor pigment is one of the main influencing factors as a coloring agent, and in order to give full play to the coloring power and the vividness and obtain good spectral characteristics, pigment particles are required to be dispersed in the pigment photoresistor in a fine, uniform and stable state as far as possible, and the pigment dispersion-color paste with fine and stable particle size is mainly obtained by selecting high-grade organic pigment varieties and adopting an efficient dispersion treatment process.
In order to improve color reproducibility and brightness, it is generally desirable that a colored layer formed of colored patterns of three primary colors of red, green, and blue in a color filter have high density and good light transmittance. However, a coloring composition containing an organic pigment at a high concentration must be used for a colored layer at a high concentration, and when the content of the organic pigment is increased, the content of other components of the coloring composition needs to be relatively reduced, which leads to problems that the dispersion stability of the organic pigment is not good and the coloring composition cannot be stably stored, and on the contrary, the light transmittance of the colored layer is decreased. Therefore, the dispersion stability of organic pigments is the first improvement to increase the light transmittance.
The color paste for the color photoresist is a core material in the liquid crystal display industry, the requirement cannot be met only by a single pigment in order to improve the color vividness and the brightness, although the brightness can be improved by the light quantity of a backlight source, the electricity consumption is high, the temperature rise of a panel brings many adverse effects, and meanwhile, the problem of the contrast ratio cannot be well solved.
