What are PMVA displays?
PMVA stands for Passive Matrix Vertically Aligned. It refers to a technology in which the molecules are oriented orthogonal (“vertically”) with respect to the display surface. The resulting optical effect is a very dark background color with a very wide and symmetric viewing angle.
Vertical alignment is used in active matrix displays in different configurations knows and PVA or MVA. In passive (PMVA) displays multiplex addressing is used and the number of rows that can be addressed is limited to a maximum of about 64 based on currently available materials. In PMVA technology the contrast ratio and viewing angle is a direct trade-off with the multiplex ratio. At high multiplex ratio certain STN-type displays have better optical performance.
PMVA displays are by nature negative mode displays, meaning they have a black background color. Therefore the most popular application is in transmissive display modules with white or colored LED backlight. The technology is very popular in automotive applications.
The high contrast of PMVA displays allows for color zones that can be created by printing color filters on the outside rear surface of the display cell or by using multi-zone LED backlights.
