Multidomain vertical alignment (MVA) LCD technology

Developed over 20 years ago, MVA brings much-improved contrast and viewing angles to display screens.

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.
