Ambient Light Sensors

Typically, ambient light sensors are the backing lights in many LCD types of displays.

How do ambient light sensors work?

They automatically adjust display brightness on many devices by sensing changes to your environment like lights on or off, how close a device is to you and more.

Features and benefits:

  • Operate well in a variety of sources (from natural sunlight to fluorescent)
  • Automatic adjustments based on environment analysis
  • Light sensitivity and response curve configured with the human eye in mind
  • Stable over specific temperature ranges

Where can ambient light sensors be used?

  • Touch panels
  • Audio visual equipment
  • Home appliances
  • Laptops
  • Mobile phones
