Dynamic scattering mode

from Wikipedia, the free encyclopedia

The dynamic scattering mode (DSM, dt. Dynamic scattering mode ) is the functional principle of the first commercially available liquid crystal screens . This principle was developed in 1967 by George H. Heilmeier .

A nematic liquid crystal layer located between two transparent electrodes is set into turbulent motion by applying an electrical voltage . As a result, strong light scattering occurs on the liquid. It changes from a transparent state to a milky-looking liquid. This allows individual pixels of a display to be switched.
