Physical performance of the LCD

2017-03-13

    Liquid crystal panel is the basic component of liquid crystal materials. Because liquid crystal is between solid and liquid, it not only has the optical properties of solid crystal, but also has the flow properties of liquid, so it can be said to be an intermediate phase. To understand the photoelectric effect of liquid crystals, we must explain the physical properties of liquid crystals, including their viscosity, elasticity, and polarization.

 

   The viscoelasticity and elasticity of liquid crystals can be described as liquids with displacement properties from a hydromechanical point of view. Depending on the direction of the force, there should be different effects. It's like throwing a stick into a running river. The stick started to flow. After a while, the long axes of all sticks will naturally turn in the same direction as the river. This means that the flow pattern with the lowest secondary viscosity is also the physical model with the lowest free energy of flow. In addition, liquid crystals have not only viscous reactions, but also elastic reactions. They're all external oriented. Thus, when light is injected into the liquid crystal material, it will inevitably move in line with the arrangement of the liquid crystal molecules, resulting in a naturally deflected image. As far as the electronic structure of the liquid crystal molecule is concerned, it has a strong ability of electron conjugate motion. Therefore, when the liquid crystal molecule is affected by the external electric field, it is easy to polarize and produce induced dipole, which is also the source of the interaction force between the liquid crystal molecules. Generally speaking, the LIQUID crystal display used in electronic products is to use the photoelectric effect of liquid crystal, through external voltage control, and then through the refractive properties of liquid crystal molecules, and the ability to rotate light to obtain light and shade (or visual optical contrast), so as to achieve the purpose of imaging.
