[0002] Liquid crystal film is a protective film for mobile phone screens, LCD screens and other display devices. It was first used to protect mobile phone screens. With the development of electronic products, liquid crystal film is gradually used to protect the screens of various electronic devices. Applying liquid crystal film on the screen can not only prevent the screen from being scratched and oily, but also reduce the fatigue of the user's eyes.

[0003] When liquid crystal film is produced, the main raw material is liquid crystal. Liquid crystal must be fully stirred before use before it can be poured. Liquid crystal with solid chiral agent added must be heated to 60 degrees Celsius, then quickly cooled to room temperature and fully stirred. And it cannot be left still for too long during use. Especially low threshold voltage liquid crystal, because low threshold voltage liquid crystal has these different characteristics, so when using these liquid crystals, you should pay attention to: after the liquid crystal is taken from the original bottle, the original bottle should be sealed and stored in a light-shielded manner in time to reduce the time of exposure to the air. Generally, too long exposure to the air will increase the leakage current of the liquid crystal, and the liquid crystal is not convenient to be in contact with the air for a long time.
