Introduction

Color filter is one of the most important components in flat panel display (FPD), especially liquid crystal display (LCD). The color noise backlight is separated and purified into three pure primary colors of red, green and blue that meet the chromaticity requirements. The color gamut, brightness, contrast and saturation of the LCD are all The color filter is usually prepared by coating a colored photoresist on a glass substrate to form a film, and then photolithography is performed by ultraviolet light. To form a pattern. Solid content, viscosity, film retention, chromaticity, brightness and contrast, chemical resistance, solvent impact resistance and solubility in developer are the key factors affecting color quality. Important indicators of color photoresist materials, these indicators will affect the fluidity, film forming properties, quality, life, color filter preparation process, and even transportation and manufacturing costs. Therefore, it is necessary to establish a color photoresist performance test method. GB/T 43793 aims to provide test methods for various properties of color photoresists and is intended to consist of three parts. --- Part 1.Physical and chemical properties. The purpose is to give and provide test methods for the physical and chemical properties of color photoresists. --- Part 2.Optical properties. The purpose is to give and provide test methods for the optical properties of color photoresists. --- Part 3.Reliability. The purpose is to give and provide a test method for the reliability of color photoresists. Color photoresist test method for flat panel display Part 2.Optical properties
