      Description

      DESCRIPTION
      Nematic liquid crystals, in particular conditions, assume locally and sometime only temporarily configurations characterized by a biassic order. This fact allows to connect between them uniaxial nematic textures with different topology without complete fusion of the nematic order, i.e. without the need to reduce the scalar order parameter to zero. The control of these transitions with electric fields allows to realize bistable or multistable displays of new conception. In fact two bistable or multistable textures are separated from a barrier of a well defined potential that it is determined from a biassic intermediate state, that connects said textures, determining the reorientation without rotation of the nematic director. Such mechanism is known in scientific literature as "order reconstruction".; From now on in this document it will be indicated as "Biaxial Order Reconstruction in Nematics" or with acronym "BORN". The scope of the present invention is to realize mixtures of calamitic nematic liquid crystals with materials that favour the tendency to assume a biaxial order, in order to reduce the external electric field intensity necessary to reconstruct of the order.

      APPLICATION
      -High definition and low consumption bistable displays
      -Paper like display
      -Fast optical shutters with intrinsic memory
      -New optical visualization devices (smart card, smart label, etc.)

      ADVANTAGES
      -Lowering of the electric threshold of bistable liquid crystal display and therefore simplification of the electronic control unit to address high definition liquid crystal display.
      -The bistability allows to reduce the power consumption of the display because the image on the display is retained by its intrinsic memory and the power is need only to refresh the image.
      -This technology can be used in many electro-optical devices and in particular in the field of e-paper display, currently required, but not available on the market.

      STAGE OF DEVELOPMENT
      Prototype.
