Patent number: 11114025Abstract: A method is proposed for sensing light being incident on an electronic device. The electronic device comprises a display and a light sensor arrangement which is mounted behind the display such as to receive incident light through the display. The method comprises the step of repeatedly switching the display on and off depending on a modulation signal, wherein a sub-frame is defined by an on-state and a consecutive off-state of the display. The modulation signal depends on at least one modulation parameter. In a first sub-frame a display brightness is set to a first level depending on a first value of the at least one modulation parameter. Then a first frame count is determined by integrating the incident light by means of the light sensor arrangement during the first sub-frame. In a second sub-frame the display brightness is set to a second level depending on a second value of the at least one modulation parameter.Type: GrantFiled: January 31, 2019Date of Patent: September 7, 2021Assignee: AMS AGInventors: Bernhard Greimel-Längauer, Joachim Lechner, Josef Kriebernegg

Patent number: 11067436Abstract: The proposed concept relates to an optical sensor arrangement comprising an optical sensor with an integrated circuit arranged in or on a substrate. The substrate comprises at least a first surface area and a second surface area. At least one optically active sensor component is arranged on or in the substrate of the first surface area. The optically active sensor component is arranged for emitting and/or detecting light of a desired wavelength range. Optically inactive sensor circuitry is arranged on or in the substrate of the second surface area. A display panel comprises an active display area and a non-active display area, wherein the non-active display area comprises a material which is optically transparent in the desired wavelength range and wherein the non-active display area at least partly frames the active display layer.Type: GrantFiled: May 8, 2018Date of Patent: July 20, 2021Assignee: AMS AGInventors: Bernhard Greimel-Längauer, Franz Lechner, Josef Kriebernegg, Herbert Lenhard, Manuel Hoerbinger, Dan Jacobs

Patent number: 11029197Abstract: An optical sensor arrangement has an integrator, a photodiode for providing a current corresponding to a first polarity, a comparator coupled to the integrator for comparing a voltage with a threshold voltage to provide a comparison output, a reference charge circuit and a control unit. The reference charge circuit is coupled to the integrator for selectively providing first charge packages of a first size or second charge packages of a second size. The control unit is configured to control operation in a calibration phase, in an integration phase and in a residual measurement phase. During the calibration phase, the reference charge circuit provides one of the first charge packages and one or more of the second charge packages to the integrator until the comparison output changes. A reference number is determined corresponding to a number of the second charge packages provided.Type: GrantFiled: June 8, 2018Date of Patent: June 8, 2021Assignee: ams AGInventors: Bernhard Greimel-Längauer, Peter Bliem

Patent number: 10705211Abstract: An optical proximity sensor arrangement comprises a first sensor unit with a first emitter and a first detector and a second sensor unit with a second emitter and/or a second detector. The first detector is configured to detect light being emitted by the first emitter and, if applicable, by the second emitter, and being at least partially reflected. If applicable, the second detector is configured to detect light being emitted by the first emitter and being at least partially reflected. A distance between the first emitter and the first detector is, if applicable, less than a distance between the first detector and the second emitter and, if applicable, less than a distance between the first emitter and the second detector.Type: GrantFiled: January 12, 2017Date of Patent: July 7, 2020Assignee: ams AGInventors: Dan Jacobs, Bernhard Greimel-Längauer
