Publication number: 20140340598Abstract: 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).Type: ApplicationFiled: January 19, 2012Publication date: November 20, 2014Applicant: Sony Mobile Communications ABInventors: Allan Johansson, Jonas Jönsson, Damir Kajic, Tomas Kulle, Magnus Midholt, Björn Rosqvist, Peter Åberg

Publication number: 20140176485Abstract: 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.Type: ApplicationFiled: December 20, 2012Publication date: June 26, 2014Applicant: SONY ERICSSON MOBILE COMMUNICATIONS ABInventors: Per Holmberg, Tomas Kulle, Bjorn Rosqvist, Gunnar Klinghult, Allan Johansson, Lars Knutsson, Georgeta Anton, Peter Aberg

Patent number: 8600450Abstract: A device includes a graphical user interface configured to receive a user input by user exertion of force onto the graphical user interface. The device further includes a detection logic operatively connected to the graphical user interface and configured to produce a signal including data indicative of a first amount of force exerted at a location on the graphical user interface. The device also includes an indication logic operatively connected to the detection logic and configured to determine based on the signal including data indicative of the first amount of force exerted at the location on the graphical user interface that the first amount of force is insufficient to command the device to perform an action based on the user input. The indication logic is further configured to produce a signal including data indicating that additional force must be exerted to command the device to perform the action.Type: GrantFiled: June 5, 2012Date of Patent: December 3, 2013Assignees: Sony Corporation, Sony Mobile Communications ABInventors: Henrik Bengtsson, Sarandis Kalogeropoulos, Olivier Moliner, Bjorn Rosqvist, Martin Granstrom, Peter Aberg
