Product Features
Our P3.91 Energy-saving LED Display utilises advanced common cathode technology to improve energy efficiency and reduce excess heat. It operates at an average of 14.6°C lower than traditional common anode systems and consumes more than 20% less power, ensuring long-term energy savings and stable performance in outdoor environments.
The energy-saving LED displays are available in large cabinet sizes, with a standard size of 1m × 1m (1 Cabinet= 1 square metre). Customised cabinet sizes are also available to suit various outdoor applications such as stadiums, commercial plazas and building facades.
The energy-efficient LED display supports a highly modular structure that allows seamless 90° corner splicing for immersive naked-eye 3D visual effects. It allows for front and rear maintenance, rigid inter-module connections, and wall mounting, effectively reducing structural complexity and cost.
The energy-efficient LED display is housed in an all-aluminium enclosure consisting of die-cast aluminium modules and a lightweight aluminium frame. Aluminium series LED display adopts aluminum profile cabinet, this structure weighs 20% less per square metre than traditional iron cabinets, reducing transport and installation loads. The display module is die-cast aluminum material, fireproof, even in high ambient temperature, will not deform.
The energy-saving LED display uses a multi-layer heat dissipation system. It features a double-layer power layout and aluminium modules with excellent thermal conductivity for superior thermal management without air conditioning, providing high reliability and extended life even in harsh outdoor conditions.
Applications
Aluminum Advertising Outdoor LED Displays are widely used for various of outdoor application fields, such as the Exterior wall of building, Public spaces, Commercial plazas, and Landmark buildings,Hanging Garden, Government Cultural Plaza, Bus Station, Vertical Advertising aside road, etc.
