摘要： 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. Finally, an ambient light level is determined depending on the first, second and third signal counts.

The receiving circuit (20) comprises an output node (A20) to provide an output signal (Vout2) in dependence from the distance of the proximity sensor (1) from the target (2). The receiving circuit (20) comprises a crosstalk compensation circuit (100) comprising a first charging circuit (110) to provide a first charge for for coarse crosstalk compensation and a second charging circuit (120) to provide a second charge for fine crosstalk compensation. A control circuit (30) sets an amount of the first and the second charge so that the output signal (Vout2) of the crosstalk compensation circuit (100) is dependent on the useful component (RSI) and independent on the noise component (RS2) of the reflected signal (RS).

摘要： 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. Then a second frame count is generated by integrating the incident light by means of the light sensor arrangement during the second frame. Finally, an ambient light level is determined depending on the first frame count and the second frame count.

摘要： 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. The optical sensor and the display panel are stacked such that, with respect to a main direction of display emission, the first surface area is arranged below the non-active display area and the second surface area is arranged below the active display area.

摘要： A circuit arrangement comprises a first terminal for connection to a voltage source, a second terminal for connection to a first current sink and a third terminal for supplying a potential signal. A first diode string can be connected to the voltage source on the anode side and to the first current sink on the cathode side. The third terminal can be coupled to the cathode side of the first diode string by a resistor. An adjustable reference current sink is coupled to the third terminal, for generating a reference current, and comparison unit coupled to the third terminal on the input side for providing a short-circuit detection signal in dependence on a difference between the potential signal and an adjustable reference voltage. The potential signal can be supplied in dependence on a first short-circuit voltage across the first diode string and in dependence on the reference current.

摘要： 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.

摘要： A control system for a gesture sensing arrangement with at least one sensor operates the sensor in a proximity mode. The control system receives data sets generated by the sensor and based on these data sets determines whether an object is present in a vicinity of the sensor. When an object is detected in the vicinity the control system operates the sensor in a gesture mode. Based on further data generated by the sensor the control system determines an end of a gesture, and operates the sensor in the proximity mode.
