On March 13, Ge Longhui | Rijiu Optoelectronics (003015.SZ) said that currently the main suppliers of wet and dry optical films are Japanese manufacturers. Currently, mainstream folding screens have several main defects. One is that the plastic texture is strong, and the folding marks in the middle are prominent. An anti-reflection function must be added to increase the texture while reducing reflection. In addition, depolarization is being implemented for the purpose of cost control and improving the lifespan of OLEDs. In this case, line reflection will increase (about 5% reflection will increase to about 7.5%). The advantage of the dry method is that reflection is lower than the wet method. The company's optical films are mainly dry. Currently, with client samples, the feedback is still quite confident.
