Hardware Design Guide to Smartphone Ambient-Light Sensing (.PDF Download)

May 3, 2016

Since the backlight of the LCD panel in a smartphone accounts for around 40% of the device’s total power consumption, one can benefit greatly by adjusting the brightness in response to changes in ambient-light levels. In a relatively dark environment, the brightness of the display can be reduced to save power. This is also easier on the user’s eyes, thus improving the user experience at the same time...
