Um bom display LED colorido de alta-definição para ambientes externos- não deve ter apenas as características de display de alta-definição, baixo consumo de energia, ângulo de visão controlável e ajustável, nível de proteção IP67, etc. ., mas também exigem um design estético que tenha sua própria alta transparência e não afete a aparência do edifício. Pode ser único na exibição de mídia de publicidade ao ar livre.
Outdoor full-color LED display has become the darling of outdoor media in the new era. Thanks to the rapid development of outdoor advertising, it is growing rapidly at a rate of more than 25 percent every year. long life. Make the full-color LED display an excellent carrier for outdoor advertising.
So, in order to meet the requirements of outdoor display, what advantages should the outdoor full-color LED display have?
1. Wide viewing angle and wide geographical coverage
The main task of the outdoor high-definition full-color LED display is to advertise and promote the image. Therefore, allowing more audiences to see the picture is the primary goal of the outdoor high-definition full-color LED display. It adopts a large viewing angle design to cover the largest range. viewing angle.
2. High protection level
Usually outdoor LED displays have a large installation area, and most of them are installed in densely populated places, so special attention should be paid to the protection level of the display, especially in the southeast coastal areas where typhoons often occur. Its design should consider the solid foundation of the steel structure, wind load, waterproof, dust-proof, moisture-proof and many other factors, and the protection level should be IP65 and above to prolong the service life of the display screen and enhance the reliability.
3. High-definition display effect to better present the advertising screen
As the main carrier of video advertisement dissemination, outdoor high-definition full-color LED display needs to have high-definition display effect. These include high resolution, high brightness, high contrast, etc. High resolution ensures that high-quality advertising pictures can be well presented; high brightness ensures that the picture can be clearly displayed under direct sunlight; high contrast is the color of the picture. A strong guarantee for uniform and delicate images.
4. Do a good job of ventilation and heat dissipation to resist high temperature
When the outdoor LED display works, it will generate a certain amount of heat. If the ambient temperature is too high and the heat dissipation is poor, the LED chip and related integrated circuits may not work properly, or even be burned, so that the LED display system cannot work normally. The label display should be equipped with a cooling fan or an air conditioner, especially for screens that need to work in high temperature subtropical and tropical regions for a long time.
5. Low energy consumption, energy saving and emission reduction
Outdoor full-color LED displays must respond to the government's call, and energy conservation and emission reduction must be implemented as important standards in manufacturing, including product power consumption, product scattering performance, and the amount of steel required for product installation.
6. Lightning protection and grounding to prevent leakage accidents
For lightning protection, the main body and shell of the LED should have good grounding measures, and the grounding form should be considered according to whether the display screen is set independently or attached to the outer wall of the building.
At the same time, the integration of electronic components in outdoor LED displays is high, and its sensitivity to anti-interference is also getting higher and higher. In order to minimize electromagnetic interference, lightning protection devices should be installed on the display and buildings.
