    Abstract: A light source color coordinate estimation system and a deep learning method thereof are provided. The light source color coordinate estimation system includes a plurality of photo detectors, a normalization calculation circuit, and a neural network. The photo detectors generate spectral responses after receiving a beam emitted by a light source. The spectral responses respectively have different detection wavebands and energy integral values corresponding to the detection wavebands. The normalization calculation circuit respectively divides the energy integral values by a largest of the energy integral values to generate a plurality of normalized energy integral values. An input end of the neural network receives the normalized energy integral values and converts the normalized energy integral values into an estimated color coordinate. An output end of the neural network outputs the estimated color coordinate.

    Abstract: A sensor package and a display device are provided. The sensor package is disposed inside the display device. The sensor package includes a substrate, a plurality of sensor elements, a shielding cover, a first polarizer, and a second polarizer. The plurality of sensor elements and the shielding cover are disposed on the substrate. The shielding cover covers the plurality of sensor elements. When light passes through the first polarizer, the light forms a first polarized light beam. When another light passes through the second polarizer, the another light forms a second polarized light beam. A first polarization direction of the first polarizer is different from a second polarization direction of the second polarizer.

    Abstract: The present disclosure relates to an optical sensing module, a system and a method for operating the optical sensing system. The optical sensing module includes a light emitter that emits a sensing light in a specific wavelength range and a photodiode unit. The photodiode unit includes a first photodiode used to sense a first wavelength light, a second photodiode used to sense a second wavelength light, and a third photodiode used to sense a third wavelength light. The optical sensing module implements a proximity sensor by operations of the second photodiode and the third photodiode, or a biometric sensor by operations of the first photodiode, the second photodiode, and the third photodiode. The photodiode unit receives a reflected light from an object to be detected so as to determine if the object is proximal, and then determine whether or not the proximal object is human skin.

    Abstract: A sensor package includes a substrate, a light sensor disposed on the substrate, at least one optical filter disposed on the light sensor, and an optical functional layer that is light-permeable, is disposed on the substrate, covers the light sensor and the optical filter, and includes multiple light-scattering particles. The light sensor has a light receiving region, and receives light through the light receiving region. The optical filter covers the light receiving region. When the light passes through the optical filter within an incident angle range and is received by the light receiving region, the light sensor responds to a wavelength range of the light, and a response spectrum is obtained. Within the incident angle range, an absolute value of an offset measured at a crest of a waveform of the response spectrum is less than or equal to 10 nm. An electronic device is also provided.
