Publication number: 20220109442Abstract: An apparatus includes a display screen, and an optical proximity sensor module disposed behind the display screen. The optical proximity sensor module includes a light emitter operable to produce light having a wavelength for transmission through the display screen toward a target object, and a light sensor operable to sense light reflected by the target object and having the wavelength. The optical proximity sensor module can includes means for reducing a maximum energy density of a light beam produced by the light emitter. The means for reducing the maximum energy density of the light beam is disposed between the light emitter and the display screen so as to intersect the light beam produced by the light emitter. In some cases, there are multiple light emitters collectively operable to provide sufficient optical energy for proximity sensing without producing a visible spot on the display screen.Type: ApplicationFiled: January 30, 2020Publication date: April 7, 2022Inventors: Jian Liu, Klaus Schmidegg, Whitney Hernandez, Helmut Theiler, Josef Kriebernegg, George Richard Kelly, Matt Kroese

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
