HVA Technology
HVA technology refers to the PSVA (Polymer Stabilized Vertical Alignment) technology independently developed by TCL CSOT, "H" is taken from the initials of CSOT (Huaxing in Chinese pinyin). PSVA refers to that by adding a small amount of polymer monomers (Monomer) to the liquid crystal molecule, resulting in the liquid crystal polarization dumping under the action of voltage, the pre-tilt angle is formed on the surface of the aligned PI (Polyimide) layer, and the reaction of the polymer monomers induced by irradiation of UV (ultraviolet) light will form a polymer deposited on the PI surface, which fixes the pre-tilt angle of the liquid crystal on the PI surface, and the alignment of liquid crystal molecules is achieved.
