  • Patent number: 9851796
    Abstract: Disclosed are tactile keys and methods for their production and use. The tactile key may include a substrate; a conductive layer disposed on at least one region of the substrate; a porous layer disposed on at least a portion of the conductive layer; an insulating layer disposed on regions of the substrate that surround the conductive layer and the porous layer to form a well, the well having sidewalls defined by the insulating layer, and a bottom surface at least partially defined by the porous layer; an electroactive polymer composition disposed in the well; and a flexible layer having a conductive coating on at least a portion of a surface facing the electroactive polymer composition, the flexible layer covering the well and at least a portion of the insulating layer surrounding the well. When the tactile key is depressed, an electric field is activated causing the electroactive polymer composition to move towards the flexible layer to provide a tactile feedback.

  • Publication number: 20110311789
    Abstract: Flexible substrates can be temporarily attached to a rigid carrier for processing a surface thereof by depositing a joining material at one or more contact points between a flexible substrate and a rigid carrier, contacting the flexible substrate and the rigid carrier at the one or more contact points; and exposing the one or more contact points to a temperature of between 219° C. and 1000° C. and under conditions suitable for attaching the flexible substrate and the rigid carrier at the one or more contact points via the joining material. Examples of suitable joining materials include, but are not limited to soldering or brazing materials. Such supported substrates can be used for preparing flexible displays comprising at least one electronic component and/or circuit on a surface of the flexible display.

  • Patent number: 6242115
    Abstract: Organic light emitting devices are comprised of an organic charge carrier layer formed from a charge carrier material that is capable of forming a stable glass due to the presence of a compound having an asymmetric molecular structure in the charge carrier material. For example, the OLED may contain hole transporting layers comprised of compounds having an asymmetric molecular structure in which hole transporting substituents are asymmetrically located around a core atom or core chemical group. The core atom may be a nitrogen atom or the core chemical group may be comprised of a single phenylene group or a biphenylene group which is substituted with at least two hole transporting amine groups, wherein at least one of the amine groups is different from at least one other amine group.
