The photodiode (Photo Diode) and other photosensitive elements (Detector) sense the intensity of the visible light of the incoming ambient light source, and the signal detected by the photosensitive element is amplified through the amplifier (Amplifier), and the current signal is converted into a voltage signal at the same time. Through the Analog Digital Converter (Analog Digital Converter), the continuous signal in the analog form is converted into a digital signal. The back circuit of the electronic device can perform response functions according to the intensity of the light source; advanced ambient light sensing, except that it can be sensed In addition to the ambient light intensity, the photosensitive element can still sense the red (R), green (G), and blue (B) colors in the ambient light source and adjust the color temperature of the OLED (Organic Light-Emitting Diode) panel or white balance.

ALS Color Sensor

Color sensor can detect not only the intensity of environment ambient light and also the color information of the environment. This information is used to adjust the smartphone display color temperature or can be used to assist the camera white balance.

ALS Flicker Sensor(Flicker detection sensor)

Flicker detection sensor can detect the flicker frequency of the ambient light and is used to assist the camera to eliminate the flicker effect.
