Abstract: The present disclosure describes a method and apparatus that can be used to determine various characteristics of ambient light when an ambient light sensor is located behind a display screen. The strategy of the disclosure relies, at least in part, on spectral decomposition of ambient light measurements into components (e.g., red, green, and blue components of an Organic Light Emitting Diode (“OLED”) display screen and ambient light). Following the spectral decomposition technique, statistical analysis are performed on the measurement data to remove the OLED light components from the measurement. This technique enables determinations such as ambient lux and correlated color temperature independent of the content displayed on the screen.

Abstract: A system includes a first spectral modulator, a second spectral modulator, a light guide optically, a photodetector, and an electronic control device. The first spectral modulator receives sample light, and modulates the sample light according to a first spectral response pattern to produce first modulated light. The second spectral modulator receives the first modulated light from the first spectral modulator via the light guide, modulates the first modulated light according to a second spectral response pattern to produce second modulated light, and transmits the second modulated light to the photodetector. The photodetector measures an intensity of the second modulated light incident on the photodetector, and generates one or more signals corresponding to the intensity of the second modulated light. The electronic control device determines a spectral distribution of the sample light based on the one or more signals.

Abstract: The present disclosure describes a method and apparatus that can be used to adjust for distorted ambient light readings caused by the ambient light sensor being located behind the display screen. The strategy of the disclosure relies, at least in part, on spectral decomposition of ambient light measurements into independent sources (e.g., red, green, and blue display components of an Organic Light Emitting Diode (“OLED”) display screen and ambient light). Following the spectral decomposition technique, a more accurate ambient light measurement can be obtained in some instances. This technique enables determinations such as ambient lux and correlated color temperature independent of the content displayed on the screen.

Abstract: Techniques are described for portable computing devices and other apparatus that include an ambient light sensor. The techniques can be particularly advantageous for situations in which the ambient light sensor is disposed behind a display screen of a host device such that ambient light detected by the sensor passes through the light emitting display before being detected by the sensor.
