Принадлежит: Toray Advanced Materials Korea Inc

A dielectric adhesive film for an electronic paper display device. A lower electrode to which voltage is applied and an image upper electrode coated with charged particles whose colors are changed depending on the applied voltage are attached to the adhesive film. Thickness of the adhesive film is controlled to be uniform and constant, and a resistance value in the thickness direction of the adhesive film, i.e., a resistance value in the direction where an electric field is formed, is controlled without changing adhesive properties and reliability as the thickness of the adhesive film is controlled. Since loss of the applied voltage is minimized and the charged particles are freely driven, driving performance of the display device is excellent although a high voltage is not applied in driving a flexible display device, such as a flexible LED, an organic electro luminescence (EL) element including an electronic paper, and the like.

The disclosed latex system comprises a one-component, closed-cell, semi-foam, mastic sealant using gas-filled, flexible, organic microspheres to create a product that is elastic and compressible under pressure without protruding in an outward direction when compressed, thereby allowing the applied sealant to compress in an enclosed, maximum-filled channel unlike typical mastic sealants (while retaining the ability to rebound). This allows the sealant to function as a gasket, and, once fully cured, to have properties including vibration damping, insulating, and condensation resistance. The sealant can be formulated as an air barrier or a vapor barrier and at various degrees of moisture resistance. It may be applied by different packaging variations including aerosol can (bag in can or bag on valve), airless sprayer, cartridge tubes, foil tubes, squeeze tubes, and buckets to be applied using a brush, trowel, spatula, etc. The disclosed mastic sealant can also be formulated to be smoke-resistant and flame-resistant.
