Use of Light Sensors to Enable Smart Features in Energy Efficient ElectronicsBrightness Control for LCD Screens Adjusting the intensity of LCD screens – based on the amount of ambient light – can conserve energy and deliver an appropriate amount of screen brightness for users.Energy can be saved for applications powered from the mains, such as LCD TVs, monitors, and street lighting; and for battery powered applications, such as smart phones, portable medical devices, video and still cameras, personal navigation systems, portable gaming, and educational toys. Screen brightness intensity could be adjusted based on changes in ambient sunlight, room lighting, or other light sources.Such adjustments can be made automatically through the use of ambient light sensors, which therefore serve as natural companions to LED drivers that control screen brightness.Ambient light sensors that precisely match human eye light response characteristics enable higher levels of energy efficiency, while maintaining screen brightness levels that are pleasing to the eye. Features of interest when selecting ambient light sensors: *Photopic light response for consistent readings across different light sources *Dynamic dark current compensation, enabling accurate low light level measurement ranges from 0.01 lux to full sunlight *Linear response over the full operating range 2*Analog outputs to provide current or PWM outputs; digital outputs to communicate over an I C bus *Direct lux measurement output with 16-bit resolution for maximum accuracy ON Semiconductor provides a variety of ambient light sensors with analog and digital outputs.These integrated ambient light sensors typically require no external components.
