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, and the inverter will change the brightness of
panel.
Each step has its own illuminate range according different environment illumination. This technology
makes the use of visual application more friendly and intelligently.
