Auto/Brightness/ Light sensor

Technology Details

What is this technology?

The lighter sensor measures the outside brightness according to different environments and sends the information to display. Display will adjust the brightness automatically.

With lighter condition (Outdoor/Sun-light) the brightness will increase; in the opposite condition, the brightness will be decreased to fit darker environment.

 

How does this technology work?

 

Light sensor detect the change of illumination outsiee, then it send the signal to MCU via Iˆ2C interface. MCU will ask inverter to switch the brightness if the outside illumination was change over the default.MCU will transmit PWM signal to the inverter, amd the inverter will change the brightness of panel.
