  • ELECTRICALLY CONTROLLABLE DEVICE HAVING VARIABLE DIFFUSION BY LIQUID CRYSTALS, AND METHOD FOR SAME
    Publication number: 20230152649
    Abstract: A device having variable scattering by liquid crystals includes a stack with a first electrode, an electroactive layer with liquid crystals being stabilized by the polymeric network, and a second electrode. The material exhibits, from a temperature referred to as T1, a mesophase referred to as P. At a temperature T? greater than or equal to T1, the stack is capable of exhibiting at least three stable and reversible scattering states in the visible range and a variable color.
    Type: Application

  • Electrically controllable device having variable diffusion by liquid crystals, and method for same
    Patent number: 11598986
    Abstract: A device having scattering which can be varied by liquid crystals includes a stack with a first electrode, an electroactive layer with the liquid crystals being stabilized by the polymeric network, a second electrode. The material exhibits, starting from a temperature referred to as T1, a mesophase referred to as P. At a temperature T? greater than or equal to T1, the stack is capable of exhibiting at least three variable scattering states, which are stable and reversible, in the visible region.
