  • Publication number: 20140340598
    Abstract: A touch panel is provided. The touch panel comprises a carrier panel (400), a first electrically conductive layer (100), an electrically isolating layer (200), and a second electrically conductive layer (300). The first electrically conductive layer (100) is arranged on a surface of the carrier panel (400) and comprises a first pattern of a plurality of electrically separated areas (11-85). The electrically isolating layer (200) is arranged on the first electrically conductive layer (100) and comprises openings (201) providing access to at least some of the electrically separated areas (11-85) through the electrically isolating layer (200). The second electrically conductive layer (300) is arranged on the electrically isolating layer (200) and comprises a second pattern comprising a plurality of electrically separated areas (301, 302).

  • Publication number: 20140176485
    Abstract: A touch screen comprises a display displaying through a front surface of the display and a sensor system. The sensor system is interposed between a back surface of the display and a bottom surface of a housing in which the touch screen is arranged. The sensor system comprises a first electrode assembly and a second electrode assembly and is configured to sense capacitance between the first electrode assembly and the second electrode assembly. The touch screen further comprises a processor being configured to determine based on the sensed capacitance a force resulting from the touch action.
