When driving on the highway, we often see various LED display screens. These LED screens play an important role in traffic management and information dissemination. Today, SightLED will introduce highway LED display screens in detail.
Advantages of highway LED display screens
The reason why highway LED displays can play an important role in traffic management and information dissemination is mainly due to their unique advantages.
Advantages of large screens:
Generally speaking, the larger the outdoor advertising area, the more it can attract people’s attention. Compared with traditional LCD and DLP, LED screens can be spliced arbitrarily, with larger areas, wider viewing angles, and more eye-catching.
High-definition picture quality:
Today’s full-color outdoor LED display screens have a resolution of P2 or P3. Their picture quality is getting higher and higher, and the degree of refinement is getting higher and higher.
Versatility:
As a collection of sound, light and electricity, LED display screens can not only play images in rotation, but also receive multiple signal transmissions to realize real-time TV broadcasts and dynamic video playback.
Wide coverage:
Due to the large area, wide viewing angle and reasonable viewing distance of road LED screens, they have a wider, stable and repeated audience.
Energy-saving advantages
With the continuous advancement of road LED display technology, outdoor LED display screens have been able to adjust adaptively according to the brightness of the surrounding environment.
At the same time, the LED display screen itself has energy-saving advantages, and the adaptive brightness adjustment technology further reduces energy consumption and reduces night light pollution.
Improved safety:
With the improvement of the heat dissipation function of the LED screen, the improvement of the waterproof and dustproof, the high-reliability power supply design and the alternative use of combustible materials, the safety factor of using road LED screens has been continuously improved. The risk of accidents has been reduced, so it is more popular with advertisers. Since there are so many advantages, they are widely used to the road, but do you know their types?
Types of highway LED display screens
According to different uses and installation locations, highway LED display screens can be divided into the following:
Gantry-type variable electronic high-speed LED display screen
Gantry-type variable electronic information boards are the most common type of LED screens on highways. Due to their large size, they usually use cross-road gantry as a supporting structure. Remotely controlled by the main monitoring computer, the gantry LED screen can display various graphic information in real time:
- Road condition information
- Driving speed prompts
- Danger information prompts, etc.
Their main function is to timely release road condition information of different sections to drivers, publicize traffic regulations, thereby reducing congestion and accidents on highways and improving driving safety. At the same time, these display screens can effectively guide traffic and improve the efficiency of highway use.
Variable limit high-speed LED display screen
Variable limit high-speed LED display screens are mainly installed in key sections with complex road conditions or extra-large bridges.
Common shapes:
- Circular
- Single-arm suspension type.
Their main function is to display the speed limit information or brief traffic information of the section, prompting drivers to drive according to the speed limit to ensure driving safety.
Mobile traffic message screen
How to inform road users of traffic information in a timely manner during highway construction or maintenance? Fixed variable information boards may not be effective due to the limitations of construction sites and distances. The mobile traffic message screen (car screen) has the following advantages:
- Small and flexible
- Easy to install
They can be placed at the construction site anytime and anywhere to directly display traffic information, making up for the shortcomings of fixed variable information boards.
Guide (warning) screen
In order to ensure the safety of highway construction workers and vehicles, as well as the safety of other vehicles driving normally, highway operation vehicles must be equipped with eye-catching warning signs.
Guide warning screens are essential equipment for highway construction vehicles. These display screens usually use outdoor full-color plug-in technology, which has the characteristics of high brightness and strong environmental adaptability, and is suitable for long-distance viewing.
Although compared with SMD technology, DIP technology may be slightly inferior in terms of viewing angle, consistency and picture uniformity, it still has certain advantages in price. With the continuous maturity and popularization of SMD technology, the price advantage of DIP technology may gradually disappear, but at present, DIP LEDs still occupies a certain share in the outdoor LED display market.
high-speed Pole LED display
Efficient high-speed Pole LED display screens are mainly set up in the following places:
- Toll station area
- Service area and other areas
They are mainly used to provide various service information and promotional content. These display screens can provide real-time road conditions and efficiency assistance to passing drivers and passengers in a timely manner, improving the management level and external image of the road section.
The highway LED information release system not only enhances the operational efficiency and driving safety of the highway, but also improves the operational benefits, and more importantly, achieves significant social benefits.
