Its function is to reflect the light leaking through the light guide plate back, reduce light loss and increase the backlight brightness. The reflectivity of the reflective film is usually required to be above 96%. After coating with a high reflectivity coating or mirror silver plating, the reflectivity can reach above 97%, or even 100%. The main raw material of the dual-band liquid crystal reflective film is liquid crystal. The liquid crystal must be fully stirred before use before it can be poured and used. The 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 for low threshold voltage liquid crystal, because low threshold voltage liquid crystal has these different characteristics, and the stirring rod of the traditional reactor is shorter, and the traditional reactor cannot stir the upper part of the reactor during reaction stirring, so that the material reaction is not sufficient and the working rate is reduced, and it is easy to have some liquid crystals not stirred in place, which affects the pouring and use of liquid crystals.
