LCD is an organic compound with regular molecular arrangement and crystal optical anisotropy, which is between solid and liquid. When the liquid crystal is heated to a certain temperature, it will show a transparent liquid state, while cooling will show the turbidity of the crystal particles. Because it has the physical body of liquid and crystal and the physical characteristics of crystal. Liquid crystal displays are actually displays made of liquid crystal display modules. The liquid crystals in LCD monitors do not emit light when they work, but control the amount of external light passing through. When external light passes through the liquid crystal molecules, the liquid crystal molecules are arranged in different distorted states, and the amount of light passing through is also different, thereby realizing light and dark changes. Using this principle, images can be reproduced. The size of the liquid crystal molecule twist depends on the voltage difference between the two sides of the liquid crystal molecule, so as to realize the conversion from electricity to light. In other words, the passing amount of light is controlled by voltage, thereby converting electrical signals into optical signals and displaying images.
