Displaying more than 100 monitor windows simultaneously

Helping traffic flow in Qingdao  

China: A multi-functional and extra large high-definition display helps the command centre of the Qingdao Traffic Police Department make order out of seeming chaos.


Command and control is a necessity in order to get the traffic flowing on jammed city streets. This requires an advanced monitoring system, which is capable of transforming a complex traffic situation into easily understandable information that is readily available for anyone who needs it.


The Traffic Police Department of Qingdao tasked SALI Electronics System Co. with that challenge. The solution was a multi-functional, extra large high-definition display with a total image area of 70 m2. It can display more than 100 monitor windows simultaneously. Advanced optical technology ensures a clear and sharp image with vivid colours and high contrast even in the corners.


The extra large screen is a high-brightness and high-definition display. In standard view, all video information of Qingdao city – including traffic conditions of urban streets and highways – are in sight. When the display window is zoomed in, the resolution is high enough to show every detail of any vehicle, including the face of the driver.
