In order to achieve a higher resolution

higher aperture opening ratio

low power consumption TFT LCD product

the impact of different factors was analyzed. The alignment film printing quality control was strengthened

meanwhile factors involved in the process were researched and analyzed. The printing and drying conditions of alignment film

the production process of APR plate

alignment film thickness change and contraction rate

opening Ratio of APR were optimized. The method was found to control PI printing quality. Experimental results indicate that: the production line management and control scheme of TN product image quality improvement was determined by optimizing the film printing and drying conditions. APR protection film can improve Zara Particle 2% reduction

Scratch 1% reduction. Based on the orientation film thickness promotion

product segment difference and Image Sticking can be improved

meanwhile the contrast was improved 30-120 and Zara Particle 30% reduction. Through the optimization of APR mesh and opening rate

the incidence rate of sand mura was reduced to 0%.
