  • Patent number: 11886050
    Abstract: An electro-optic medium is disclosed including a continuous phase comprising a binder and a discontinuous phase comprising electro-optic material. The binder may include one or more elastomers having a Young's modulus less than 25 MPa. The electro-optic material may include capsules that encapsulate various kinds of materials capable of switching optical states, such as a plurality of charged particles dispersed in a suspending fluid and capable of moving upon application of an electric field to the suspending fluid.

  • Publication number: 20230040814
    Abstract: An electrophoretic display (100) comprises an electrophoretic medium (114) having electrically charged particles disposed in a fluid and capable of moving through the fluid on application of an electric field. An electrode (104, 120) is disposed adjacent the electrophoretic medium and arranged to apply an electric field thereto. A dielectric layer (106, 118) is disposed between the electrophoretic medium (114) and the electrode (104, 120) and has at least one aperture (107, 119) extending therethrough. The provision of the apertures (107, 119) in the dielectric layers enables the dielectric layers (106, 118) to protect the electrodes (104, 120) while reducing electro-optical kickback. When multiple electrodes (104, 120) are present adjacent the electrophoretic medium (114), more than one or all of the electrodes (104, 120) may be provided with apertured dielectric layers (106, 118).

  • Publication number: 20200354654
    Abstract: Liquid detergent compositions are disclosed which comprise one or more shell-core capsules types. The core comprises one or more enzymes, wherein the material that forms the shell is able to be degraded by at least one of the enzymes. The capsules preserve the activity properties of the enzymes during the storage of the liquid detergent composition and they release the ingredients upon the application of shear during the use of the liquid detergent composition in a washing process. The methodology also enables the presence of incompatible benefit agents in the same product, and the reduction of undesirable residue on the articles that are being washed.
