Question

What is an outdoor LED grille screen?

Answer 1

An outdoor LED grid screen is an LED display designed specifically for outdoor environments. It combines LED display technology with a grid-like structure, resulting in a unique appearance and performance features. The following provides a detailed introduction:

1. Structural Features

Grid-like design: It consists of individual LED light strips or panels arranged at regular intervals, creating a grid-like, openwork structure. This design allows the screen to maintain both display functionality and excellent transparency, allowing wind to pass freely through the screen and significantly reducing wind resistance.

Modular Design: Typically, a modular design is employed, with each module containing a specific number of LEDs and a driver circuit. This design facilitates installation, maintenance, and replacement. If a module fails, it can be quickly replaced without affecting the overall function of the screen.

2. Display Principle

The display principle of an outdoor LED grid screen is similar to that of a conventional LED screen. Both display images, text, and videos by controlling the on/off and color changes of LEDs. It uses a dynamic scanning method, rapidly illuminating each row or column of LEDs in sequence. This utilizes the human eye's persistence of vision to create the perception that the entire screen is displaying content simultaneously.

3. Performance Advantages

Excellent Ventilation and Heat Dissipation: The grille structure allows for free air circulation, effectively improving heat dissipation efficiency. This prevents LED performance degradation or damage caused by excessive temperatures during prolonged outdoor use, extending the screen's lifespan.

Strong Wind Resistance: Compared to traditional solid-core LED displays, the hollow design of outdoor LED grille screens significantly reduces wind resistance. In strong winds, they can withstand greater wind forces, reducing the risk of wind damage. They are suitable for installation in windy locations such as high-rise building facades and large billboards.

Light Weight: The grille structure reduces material usage, making the screen relatively lightweight. This not only reduces the load-bearing requirements of the mounting structure, but also facilitates transportation and installation, reducing construction costs.

Energy Saving and Environmental Protection: Outdoor LED grille screens consume relatively low power when displaying the same content. This is because the hollow sections do not need to emit light, reducing energy consumption. Furthermore, lower power consumption means less heat generation, further reducing heat dissipation requirements.

Wide Viewing Angle: The wide viewing angle meets the viewing needs of viewers from different positions. Whether viewing from the front, side, above, or below, audiences can see clear, vibrant content.

4. Application Scenarios

Architectural Curtain Wall Decoration: These can be installed on the exterior walls of buildings as dynamic decorative elements, displaying a variety of exquisite graphics and videos. They can also be integrated with the building's lighting system to create unique visual effects, enhancing the building's aesthetics and visibility.

Outdoor Advertising: In crowded locations such as commercial streets, squares, and transportation hubs, outdoor LED grid screens can display advertising content, attracting attention and improving advertising effectiveness. Their high brightness and high definition display enable clear display of advertising information even in strong outdoor lighting.

Stage Performance Background: In large-scale concerts, gala performances, and other stage performances, outdoor LED grid screens can serve as stage backgrounds, changing images in real time according to the rhythm and content of the performance, creating a stunning visual effect and enhancing the performance's appeal and appeal.

Stadium Display: These can be installed inside stadiums to display game information, scores, athlete introductions, and other content, providing audiences with clear visual information. At the same time, it can also play exciting game moments and advertising videos to enrich the audience's viewing experience.

Core Analysis of Outdoor LED Grid Screens

I. Product Essentials and Structural Advantages

LED grid screens are a grid-like display composed of LED light strips. They feature a hollow design with gaps between the strips, creating a light-permeable and air-permeable structure. Their core advantages include:

Ultra-light and Ultra-thin: They weigh approximately 60% less than traditional LED screens, with a thickness of only 85mm (such as the Aurora King product), making them easy to transport and install.

High Transparency: With a transparency of 60%-90% (e.g., for glass curtain wall applications), they allow the background scenery to show through when not illuminated, creating an "invisible display" effect.

Strong Wind Resistance: The hollow structure reduces wind resistance, making it suitable for high-wind environments such as high-rise buildings and bridges, with wind resistance far exceeding that of traditional screens.

II. Performance Parameters and Technological Innovations

Brightness and Energy Saving

Brightness can reach over 6,000 cd/m², and in extreme environments (such as those facing the sun), it can exceed 10,000 cd/m², ensuring clear visibility even in strong sunlight. Utilizing high-efficiency LEDs and a high-efficiency power supply, the display consumes approximately 150W/㎡, saving over 30% energy compared to traditional screens.

Protection Rating

Waterproof and dustproof with an IP65 rating, it withstands heavy rain and dust storms. Some models are tested for temperatures ranging from -40°C to 60°C, making them suitable for extreme climates.

Fireproof, lightning-proof, and corrosion-resistant designs extend the outdoor service life to 8-10 years.

Customization Capabilities

The display supports customizable curved and cylindrical shapes, meeting the needs of landmark buildings, creative skylights, and more.

Pixel pitch ranges from P3.91 to P16, with flexible and adjustable resolution to accommodate both near and far viewing requirements.
