P‐188: Analysis and improvement of TV product slapping bright spot defects

Abstract

In order to improve "slapping bright spot" defect that frequently occurs in the client of TV products, this paper clarified that the defect is different from the dropping red spot caused by PS shift. It is an irregular tiny vacuum bubble caused by incomplete filling of liquid crystal (LC) due to poor wetting on PI surface. With the help of effective simulation and characterization techniques, the defect can be completely eliminated through process or OC material optimization. The follow‐up can still continue to conduct in‐depth research from OC material system and LC material monomer, which gives clear direction and reference basis for new products.
