The electro-optic effect of liquid crystal refers to an electro-optic modulation phenomenon in which the arrangement state of molecules of liquid crystal changes under an external electric field, and thus the optical properties of a liquid crystal cell change accordingly. Since liquid crystals have dielectric anisotropy and conductivity anisotropy, an applied electric field changes the alignment of liquid crystal molecules to perform optical modulation, and at the same time, due to birefringence, the liquid crystals can exhibit special characteristics such as optical rotation, optical interference, and optical scattering. The LCD display screen all needs to use the bearing to rotate fixedly when the installation, and the bolster surface that the LCD bearing was used can make the surface rust owing to expose in the air for a long time, influences life.
