Defining switching directions
How it works
MVA (multidomain vertical alignment) technology is a type of VA technology. It was developed in 1966 by the Fujitsu company. In MVA displays, the starting direction of the LC molecules' switching behavior is defined in advance by protrusions. These protrusions are found on the boundary between the orientation layer and the liquid crystal layer. Each pixel consists of three subpixels, one for each of the primary colors, which can be mixed. In turn, each of these subpixels is divided into two or four further subpixels that define different switching directions. These substructures with different switching directions for the LCs improve the viewing angle dependence.
