Reasons for the Application of LCD Display Screen in Intelligent Transportation Systems

With the arrival of the information age, the construction and development of intelligent transportation systems have become increasingly important. In the transportation field serving the public, the release of information has become an important service content, and various information display devices have become the main means of public information release, including airports, train stations, docks, bus stops, highways, city roads, and parking lots.

It is understood that intelligent transportation systems generally include information sources, information processing, and information release display. The main means of information display are various multimedia display devices, such as LED screens, LCD display screens, CRT displays, PDP displays, etc.

Among them, LCD display screens are increasingly favored due to their advantages such as seamless splicing, realistic color restoration, long life, high brightness, and high reliability. At the same time, due to the environmental characteristics of road traffic, LCD display screens have become the main means of information display.

Among the many application areas of LCD display screen, traffic information display is one of the important application areas. LCD display screens are mainly used in stations, subways, airports, docks, bus stations and other places in the traffic system as the main tool for displaying passenger information.

The reason why LCD display screen can quickly open up the market of traffic information display and achieve wide application mainly has three reasons:

• With the rapid development of LCD display screen technology, the point spacing of LCD display screens is getting smaller and smaller, and high-density LCD display screens can greatly improve the resolution within a limited area, making the displayed images clearer, more delicate, and more realistic. This helps the command decision makers in the control center to process and analyze traffic dynamic situation in real-time through manual or automatic means, and to release and display traffic information and road conditions externally in order to reduce congestion levels and improve road capacity.

• The high brightness of LCD display screen is very important for outdoor LCD traffic displays. Only with sufficient brightness can they be clearly visible in sunlight.

• The price factor of LCD display screen. The high-density LCD tube core that was once unattainable is now becoming more affordable, and its competitive advantage is beginning to emerge.
