碩士 === 元智大學 === 化學工程與材料科學學系 === 105 === In the present study, the main factors affecting the thickness of the alignment film are discussed. The first one is the alignment liquid solid content. The higher the concentration is, the thicker the alignment film is, but the viscosity affects the printing quality. Main-cure oven time and temperature changes, preheating oven heating degree varies, PI liquid solvent evaporation rate is different, easy to cause uneven film thickness, hard oven is the cavity (Chamber), the temperature must be uniform , The third is A round Mesh number of changes, the thickness does have a considerable change in the quality of the display also has a relative impact. Mainly by lighting test showed uniformity and optical image observation and analysis, optical properties confirmed that the improvement of the thickness of the film to the uniformity of the display, the panel production quality in line with market demand for high image quality, high contrast technology.
