Problems solved by technology

However, the various performances of liquid crystal materials are mutually restricted. Accelerating the response speed will often bring about a decrease in the clearing point, resulting in the failure of the liquid crystal display to work in a high temperature environment, and the reduction of high and low temperature reliability. not displaying properly
