  • Patent number: 11125611
    Abstract: A method for light sensing senses the light during a sub-frame of a picture frame operated display. The sensing is performed during an adaptive observation window which is determined in dependence on the duty cycle of the operation of the display. A calculation that uses the light sensed during the observation window and the light sensed during the sub-frame delivers a value indicative of the amount of received ambient light.

  • Patent number: 11114025
    Abstract: 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.

  • Publication number: 20210199768
    Abstract: An optical device (306) includes an internal cavity and an emitter (102) disposed in the internal cavity (210). The emitter is operable to emit a first light wave (220). The optical device also includes a detector (104) disposed in the internal cavity. The detector is operable to detect a second light wave (225) that is based on the first light wave. The second light wave is susceptible to being coupled with an undesired light wave (235) that is based on the first light wave. The optical device further includes an interference filter (310) disposed on the detector. The interference filter has a filter property that causes the interference filter to attenuate the interfering light wave.

  • Patent number: 10950187
    Abstract: A method is suggested for sensing light being incident on an electronic device. The electronic device comprises a display and a light sensor arrangement mounted behind the display such as to receive incident light through the display. The method comprises periodically switching the display on and off depending on a control signal, wherein a period is defined by a succession of an on-state and an off-state of the display. A sensor signal is generated by integrating the incident light by means of the light sensor arrangement for a total integration time comprising a number of periods. A first signal count is determined from the sensor signal being indicative of an amount of integrated incident light during an on-state. A second signal count is determined from the sensor signal being indicative of an amount of integrated incident light during an off-state. A third signal count is determined from the sensor signal being indicative of an amount of integrated incident light during the total integration time.
