Advanced light pollution reduction technology
With the advantages of high brightness and high refresh rate, LED displays have become the leading displays in the industry. However, the high brightness of LED displays also causes light pollution. Many LED screens have problems of excessive brightness, frequent flashing and glare, which have caused great inconvenience to residents and traffic safety. Comsight EMC’s control system can set safety brightness parameters and safety protection for LED displays to prevent light pollution.
- Auto dimming: collect the ambient brightness in real time and adjust the LED display’s brightness automatically to synchronized with ambient environment;
- Manual adjustment: set the brightness value manually and control the LED display’s brightness precisely
- Mixed measures for adjustment: set different brightness range for different time period, then auto dimming control the brightness in the defined range.
- Switch On/Off the display by timing and remotely
