Abstract: The present disclosure relates to a method for sanitization of a surface by emission of a plurality of sanitization wavelengths, and to a device for implementing the method. The method comprises emitting light using first LEDs configured to emit the sanitization wavelengths, receiving, by a circuit, a feedback signal from a light sensor indicating a light intensity received by the light sensor during the light emission, and controlling the first LEDs with the circuit based on the feedback signal.

Abstract: A display includes a display panel and a circuit. The circuit controls the display panel according to at least one control mode such as a pulse width modulation control mode. A method for determining a state of the display includes: acquiring samples from a channel of an ambient light sensor disposed below the display panel; supplying the samples to a processing circuit; detecting, by the processing circuit and based on said samples, whether the display panel is controlled in pulse width modulation; and following detecting the pulse width modulation control mode, calculating by the processing circuit a duty cycle from the samples.

Abstract: The present disclosure relates to a light sensor comprising: an optical device comprising a first face configured to receive light and a second face, the device being configured, when the first face receives the light at a first wavelength between 1100 nm and 1600 nm, to convert the received light to the light at a second wavelength between 600 nm and 1000 nm, and to emit the light at the second wavelength through the second face; and at least one pixel having a silicon photoconversion area arranged opposite the second face of the optical device.
