  • Patent number: 8847925
    Abstract: 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 p

  • Publication number: 20130234931
    Abstract: An electronic device for visualizing data and receiving related gesture-based control input from a user, configured to obtain digital image data utilizing a number of camera entities and to derive the control input on the basis of the image data, the electronic device including a display panel for displaying data to a user, and at least one protective element integrated with the display panel and including, as disposed at the periphery region around the active area of the display panel, the number of camera entities substantially embedded therein, the protective element including material that is optically substantially transparent relative to the predetermined reception wavelengths of the optically sensitive areas of the camera entities and substantially covers the sensitive areas, the camera entities in the protective element to span at least partially overlapping fields of view substantially in front of the display panel. A corresponding method of manufacture is presented.

  • Publication number: 20130234171
    Abstract: A method and a system for forming one or more integrated light guides comprising one or more light sources and one or more light transmissive materials are disclosed. At least one of the one or more light transmissive materials is capable of transmitting light emitted by at least one of the one or more light sources. The method includes disposing the one or more light sources on one or more sides of a substrate to form an arrangement of the one or more light sources. Additionally, the method includes molding the one or more light transmissive materials onto one or more parts of one or more sides of the arrangement of the one or more light sources to form the one or more integrated light guides.

  • Publication number: 20110199340
    Abstract: Arrangement for use with a touchscreen, includes a substrate, such as an optically substantially transparent film or a film defining a through hole, the substrate including support electronics, such as printed electronics including a number of printed conductors, for providing power, control and/or communications connection to further electronic components, a number of emitters and detectors arranged on the substrate into contact with the support electronics, for emitting and detecting light, respectively, and a lightguide arranged onto the substrate such that the emitters and detectors, and optionally at least part of the support electronics, are substantially immersed in 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
