摘要： Arrangement (202) for a user input device, such as a touchscreen or a touchpad, comprising a substrate (206), such as an optically substantially transparent flex film or a multilayer film, said substrate comprising support electronics (212) for providing power, control and/or communications connection to further electronic components (210), a number of emitters and detectors (210) arranged to said substrate into contact with the support electronics, for emitting and detecting light, respectively, and a lightguide (208) provided, such as laminated, onto the substrate such that said emitters and detectors are optically coupled to the lightguide material, the properties of the lightguide including the refractive index of the lightguide material being selected and the emitters and detectors being configured so as to enable, when in use, total internal reflection (TIR) -type propagation of light within the lightguide between the emitters and detectors, and recognition of a touch on the basis of a drop in the TIR performance as determined from the detected light. A related method of manufacture is presented.

摘要： A composite laminate assembly for an electronic device provides integrated backlighting for one or more indicator shapes defined by the assembly. The assembly includes a substantially opaque cover member to obscure at least parts of the electronic device. Translucent indicator structures in the cover member define respective indicator shapes to allow backlighting to pass through the cover member. An optical matrix layer of an optically conductive material is attached to an inner face of the cover member, with a plurality of lighting devices embedded in the optical matrix layer and laterally offset from associated indicator structures. The plurality of lighting devices may be connected to an electric circuit carried on the inner face of the cover member.
