Product Description:1100 ultra-flat aluminum plate (2.0mm thick, 1200mm wide) has become the core material of the global LED light box backsheet due to its high flatness, light weight and excellent optical performance. From urban outdoor advertising to retail space signage, from traffic guidance to art installations, the lighting revolution is empowered with industrial-grade precision.
Key Benefits:
| Dimension |
Technical parameters/characteristics |
Comparison with conventional materials (acrylic/steel backsheet) |
| Optical performance |
Surface roughness Ra≤0.2μm, reflectivity ≥85% (ASTM E903) |
Acrylic is prone to yellowing, and the steel back plate requires an additional reflective coating |
| Lightweight |
The density is 2.71g/cm³, and the weight is 1/3 of the steel plate |
Acrylic is heavy and brittle, and steel backplates are expensive to handle |
| Weather resistance |
Salt spray resistant ≥ 2000 hours (ISO 9227), operating temperature -30°C~80°C |
Acrylic is prone to cracking, and the steel backplate has a high risk of corrosion |
| Processing efficiency |
The laser cutting accuracy ± 0.1mm, and it supports continuous roll-to-roll production |
Acrylic cutting dust is large, and the steel plate needs to be deburred |
| Eco-friendliness |
100% recyclable, carbon footprint≤5kg CO2/m² (recycled aluminium process) |
Acrylic is difficult to degrade, and the recycling energy consumption of steel backsheet is high |

Market Trends & Future Applications
1. Current drivers
Digital advertising exploded: the global digital out-of-home (DOOH) market grew by 12% year-on-year (2023-2030);
Lightweight demand: there is an urgent need to reduce the weight of advertising screens in super high-rise buildings (such as Burj Khalifa in Dubai);
Regulatory upgrades: EU EN 13501-1 mandates fire rating ≥B-s1, d0 for light box materials in public areas.
2. Future technology direction
Intelligent Interactive Backplane:
Integrated capacitive touch layer (developed by SCHOTT, Germany) to support gesture interaction (such as smart windows);
Case: Interactive model display screen in BMW 4S store.
Ultra-thin and flexible:
0.8mm ultra-thin aluminum plate (Japanese UACJ technology), curl radius ≤50mm, suitable for curved LED screen;
Case in point: Dome Theater at the Osaka World Expo.
Photovoltaic integration:
The perovskite film is integrated on the backplate (Oxford PV experimental stage), which is displayed while generating electricity, and the energy efficiency is improved by 25%.
The "Invisible Pillars" of the Light Revolution
With millimeter-level flatness and industrial-grade reliability, 1100 ultra-flat aluminum plate has become an irreplaceable cornerstone in the LED display ecology. From static advertising to dynamic interaction, from urban landmarks to smart spaces, it is redefining the symbiotic relationship between light and materials.
