With the continuous development and advancement of LED display technology, LED display device products have been widely used in the field of intelligent traffic information display, and have become the mainstream display mode of modern traffic information display. In the field of intelligent traffic information display, the corresponding traffic information display device product needs to display and display the current actual road traffic information in real time according to the requirements of road traffic management and traffic guidance information, wherein the LED display device product has the following characteristics in the actual engineering application scenario.
(1) LED display products can work without interruption, adapt to different environmental conditions. Since the LED display area caused by traffic information is generally outdoor, the related external environment is more complicated and varied, and the maximum temperature and minimum temperature of the workplace, rainfall, ambient humidity, air quality and extreme weather should be considered. Environmental requirements maximize the stability and reliability of traffic information display.
(2) The LED display can be remotely monitored for intelligent detection. Due to the actual use of the scene, the mounting position of the LED display for releasing traffic information is usually distributed over a large area. In this case, the traffic management control center usually needs to implement each LED display product in the field. Process Monitoring. The remote control facilitates routine maintenance and environmental inspection of the LED display, saving resources.
(3) led display has high brightness and reasonable viewing angle. The release of road traffic guidance information is mainly for road traffic participants, and the general situation is to drive the vehicle, so the viewing angle of the display product is not high. The display product needs to have high brightness, because in the case of direct sunlight on the front of the display, it is considered that the display content of the display product should maintain a certain degree of clear visibility.
