Applications/Examples of results
High Functionality of Smartphone Light Sensors Smartphone light sensors are subdivided into ambient light sensors (ALS), color/CCT sensors, RGB/multi-channel spectral sensors, flicker detection, proximity sensors, and display-under-integrated types. With the spread of OLED, narrow bezels, high refresh rates, and foldable displays, there is a shift from the traditional front opening placement to slit-type or under-screen placement. Smartphone light sensors are required to maintain high sensitivity while compensating for interference from OLED emissions and variations in panel transmittance. The competitive axis for smartphone light sensors is shifting from simple component pricing to system performance. Standard ALS and ALS + proximity sensors have a high level of maturity, with estimated gross profit margins of around 20-35%, leading to intense price competition. On the other hand, under-OLED sensing, RGB color temperature detection, flicker detection, multi-channel spectral sensing, and custom products for flagship devices face entry barriers such as optical implementation precision, algorithm adaptation, customer certification, and stable supply, potentially reaching gross profit margins of around 35-50%.
