LCD and liquid characteristics of the liquid crystal TFT Display Modules

First, it can be translated in any direction, it can be rotated in one direction, but is limited in the other two directions of rotation, which determines its crystal properties, so it is a liquid crystal mixture in between .
Let us now discuss the model of the electrical characteristics of the liquid crystal molecules. Usually charged molecules in an electric field, after being polarized. Special molecules under the influence of an electric field distribution of the electron cloud would be a molecular deformation. When the the molecular plus a transverse electric field, it will be polarized. For an isotropic medium, is equal in all directions of polarization, and does not consider the directionality of the electric field. Polarization can get the same results, so the results of this polarization in the picture called 'P'. It is a vector, an alignment direction of the electric field is finally obtained after the charge of the positive and negative poles. Some molecules can be polarized, almost all the molecules of the polarization in the different directions are different, but usually in a liquid or non-crystalline, all the molecules are randomly oriented in any direction, so the overall result to obtain an isotropic .TFT LCD Module
However, the results of the crystal anisotropy can be obtained. Wherein a direction of polarization can be obtained in three effective direction better than the other two directions.
You can see: when the direction of the electric field parallel to the long axis of the molecule polarization effect is very good; when the direction of the electric field parallel to the molecular short axis direction, the polarization effect is not very good. This is caused by the dielectric anisotropy of the many characteristics of the liquid crystal.
How does it work? When a liquid crystal molecule can be freely rotating, it has a major axis and a minor axis. The rotation of the molecule allows it to two minor axes are mutually average, which is trying to show you the pair of map: the vertical dielectric constant is the average of the two vertical dielectric constant. It can be polarized and it is usually a slightly better in the two polarized in the other direction. But because it is freely rotatable, it averaged, so that it actually has two dielectric constant, which is having the characteristics of the liquid crystal molecules. This order dielectric constant ε, or is parallel to the long axis εparallel, or is perpendicular to the long axis of the εperpendicular.lcd modules
