Novel manufacturing process for anti-glare of LCD cover and development of haze model

摘要

This paper proposes a novel manufacturing process for an AG (Anti-glare) coating for LCD cover glasses. The proposed coating method uses silk screen printing equipment and the sintering step of the tempered LCD cover glass manufacturing procedure. In general, AG films have been widely used for dealing with glare but this is not proper for an outdoor LCD display due to low durability. To keep the same durability of tempered glass, glass frit was prepared and the tempering process was applied after silk screen printing. A ZBS (ZnOB2O3-SiO2) glass frit was used and it was coated on using a silk screen process. Also, herein the performance of the proposed method is evaluated by comparing the haze values that were produced under various silk screening conditions. Based on the comparison results, the main parameters that characterize the AG effect of the proposed method were determined and a haze model was developed.
