When you drive on the city highway or stop in front of the core landmark of the bustling business district, those once heavy and closed traditional outdoor LED advertising screens are quietly being replaced by a "breathing" screen - grille screen. This transparent and lightweight display solution is becoming the new favorite of large-scale outdoor advertising media.
Grille screen, also known as hollow screen or ventilated screen, is an LED display product with a bar hollow design. It alternates light strips with permeable areas to form a louver-like structure with two core features: high transparency and light weight.
Large outdoor advertising screens are often installed on rooftops, building facades or next to highways, where wind loads are extremely high. Traditional closed screens are like "one wall" to withstand all wind pressure, posing a huge challenge to steel structures. With its hollow design, the grille screen allows the wind to pass directly through the screen, and the transmittance of mainstream products can reach 60%-80%, greatly reducing wind resistance, which is especially critical in coastal cities and high-rise projects with frequent typhoons.
Traditional outdoor LED screens weigh 50-60 kg per square meter, while grille screens can be controlled at 15-25 kg, which is only one-third of the traditional solution. Lightweight reduces the load-bearing requirements for old buildings, expands installation scenarios, significantly reduces transportation costs, makes installation more convenient, and reduces the risk of working at height.
Outdoor displays generate a lot of heat when they work, and the heat dissipation efficiency directly affects the light decay and lifespan of LEDs. Traditional closed screens rely on air conditioners or fans for heat dissipation, increasing energy consumption and potential failures. The hollow structure of the grille screen allows air to flow naturally and heat to be discharged quickly, eliminating the need for additional equipment, reducing energy consumption and reducing points of failure.
Traditional closed screens will completely block curtain walls and windows, affect lighting, and make the building look dull. The high transparency of the grille screen allows light and sight to pass through, which not only retains the advertising function, but also protects the original appearance of the building to the greatest extent, especially suitable for glass curtain walls and historical building renovation projects.
With 17 years of technology accumulation focusing on outdoor displays, Aurora King's B Pro series grille screens have become an industry benchmark.
Equipped with self-developed DIP570 lamp beads, it adopts epoxy resin fully wrapped independent sealing structure. The screen brightness is as high as 8000nit, which is still clear and vivid in the midday sun; The brightness attenuation is less than 15% within 5 years, greatly extending the service life; It supports operation in a wide temperature range of -35°C to 60°C, and has been successfully used in extreme environment areas.
The Aurora King B Pro series grille screen adopts an aluminum profile frame, the thickness of the screen body is only 70mm, the transmittance rate is up to 62%, the hollow structure effectively reduces wind resistance, the weight per square meter is much lower than the traditional scheme, and the ultra-thin design makes the building simple and beautiful; At the same time, through the dual optimization of high-efficiency power supply and DIP570 high-efficiency lamp beads, the energy consumption of the whole screen is reduced by about 30%, and the open structure forms a natural air duct, eliminating the need for additional air conditioning and cooling equipment, achieving the perfect unity of lightweight and energy conservation and environmental protection.
The 1,053㎡ hotel project in Saudi Arabia operated stably in the high temperature of 50°C and sandstorms; Argentina's 434㎡ project withstood strong winds of 100 km/h, and Kazakhstan's 616㎡ leaf screen project started normally in cold weather.
