Polymer stabilized vertical alignment (PS-VA) technology


PS-VA Technology for LC Displays

With a special PS-VA process step, this type of VA technology ensures that the liquid crystal in its black state is not completely vertical, but has a slight inclination. This is called a 'tilt', and ensures that the direction in which the LC molecules switch is prescribed locally.

Extremely fast switching times

As well as extremely fast switching times, the lack of protrusions (see MVA) increases the light transmission of the displays in its white state by up to 25 percent compared to conventional VA displays. This reduces the energy needed for backlighting – one of the most expensive components and the largest energy consumer in an LCD. PS-VA technology has been in commercial use since 2008.
