Description
The ALS-PDIC17-77B/TR8 is consisting of a photodiode and a current amplification IC.
EVERLIGHT ALS series product is a good effective solution to the power saving of display
backlighting of mobile appliances, such as the mobile phones, NB and PDAs. Due to the high
rejection ratio of infrared radiation, the spectral response of the ambient light sensor is
close to that of human eyes.
Applications
Detection of ambient light to control display backlighting
Mobile devices – mobile phones, PDAs
Computing device – TFT LCD monitor for Notebook computer
Consumer device – TFT LCD TV, Plasma TV, Video camera, Digital camera, Toys
Automatic residential and commercial management
Automatic contrast enhancement for electronic signboard
Ambient light monitoring device for daylight and artificial light
– Street light, CCD/CCTV
