  • ELECTRICALLY CONTROLLED INTERFERENCE COLOR FILTER AND THE USE THEREOF
    Publication number: 20170371224
    Abstract: The invention relates to an electrically controlled interference colour filter comprising at least two transparent electrodes, at least one nematic liquid crystal layer and alignment layers for alignment of the liquid crystals. When an electrical field is applied the liquid crystals can be realigned and thus the transmission wavelength range of the interference colour filter can be shifted.
