As the darling of outdoor media in the new era, full-color outdoor LED displays have benefited from the rapid development of outdoor advertising. They are growing rapidly at a rate of more than 25% per year. Long life. Makes the full-color LED display an excellent carrier for outdoor advertising.
However, from tens to hundreds of square meters, in order to expand the audience's field of vision and strengthen the effect of outdoor advertising, full-color LED displays are usually installed in open areas such as the roofs of buildings. The so-called "trees attract the wind", the large area and high position of the LED display is dazzling, but at the same time it has to face the test of harsh environments such as wind, frost, thunder and lightning. For this reason, a good outdoor high-definition full-color LED display not only has the characteristics of high-definition display, low energy consumption, controllable viewing angle, IP67 protection level, etc., but also requires its own high transparency and does not affect the aesthetics of the building appearance. Design can be unique in outdoor advertising media display.
Outdoor full color led display
So, in order to meet the requirements of outdoor display, what characteristics should outdoor full-color LED displays have?
1 High-definition display effect, better presentation of advertising pictures
Outdoor high-definition full-color LED display, as the main carrier of video advertising, needs to have a high-definition display effect. This includes high resolution, high brightness, high contrast, etc. High resolution ensures that high-quality advertising pictures can be presented well; high brightness ensures that the picture can be displayed clearly under direct sunlight; high contrast is the only color of the picture. Strong guarantee of uniformity and fine image.
2 Low energy consumption, energy saving and emission reduction
Outdoor full-color LED displays must respond to government calls, and energy conservation and emission reduction must be implemented as an important standard in manufacturing, including product power consumption, product scattering performance, and the amount of steel required for product installation.
3 Large viewing angles, wide geographical coverage
The main task of outdoor high-definition full-color LED display is to do advertising and image promotion. Therefore, letting more audiences see the screen is the primary goal of outdoor high-definition full-color LED display. It adopts a large viewing angle design to maximize coverage. Viewing angle.
4 High protection level
Generally, outdoor LED display screens have a large installation area and are mostly installed in densely populated places. Therefore, special attention should be paid to the protection level of the display screen, especially in the southeast coastal areas where typhoons are frequently registered. Its design should consider many factors such as the solid foundation of the steel structure, wind load, waterproof, dustproof, moisture-proof and so on. The protection level should be IP65 and above to extend the service life of the display and enhance the reliability.
5 Lightning protection grounding to prevent leakage accidents
For lightning protection, the LED main body and shell should have good grounding measures, and the grounding form should be considered separately according to whether the display screen is installed independently or attached to the outer wall of the building.
At the same time, the integration of electronic components in outdoor LED display screens is high, and the sensitivity requirements for anti-interference are getting higher and higher. In order to minimize electromagnetic interference, lightning protection devices should usually be installed on the display screen and buildings.
6 Do a good job of ventilation and heat dissipation to resist high temperature
Outdoor LED display screens will generate a certain amount of heat when they work. If the ambient temperature is too high and the heat dissipation is poor, the LED chips and related integrated circuits may not work properly or even be burned out, which will make the LED display system unable to work normally, so usually outdoor LEDs The label display should be equipped with a cooling fan or air conditioner, especially for the display that needs to work in the subtropical and tropical areas with high temperature for a long time.
