Abstract: 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.

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