​​How to determine the standard size of LED screens? ​ ​
The industry's general dimensional system is based on modules, and common specifications include:
● Outdoor advertising screen: 500×1000mm standard box, supporting horizontal/vertical seamless splicing
● Indoor display wall: 320×160mm die-cast aluminum box, thickness controlled within 45mm
● Transparent display: 1000×500mm special-shaped unit, supporting ±15° arc splicing
These basic specifications can be built through building block combinations to build a 4K/8K level display wall, with the minimum splicing seam controlled within 0.88mm.

​​Size adaptation solution for special scenarios​​
In complex spaces such as commercial complexes, three dimensions need to be considered:

1. ​​Range of sight matching​ ​: Follow the golden formula of pixel spacing = sight range (meters) / 3400
2. ​​Structural load bearing​ ​: The weight per square meter must be controlled at 35kg (indoor) or 55kg (outdoor)
3. ​​Content adaptation​ ​: The basis for selecting a standard ratio of 16:9 or 21:9 ultra-wide ratio

For example, the arc-shaped LED curtain wall used by a certain international airport built a 270° ring curtain with a radius of 18 meters through 576 500×750mm customization units, achieving a perfect presentation of 4mm pixel density at 8 meters of sight.

​​Technical support for customized sizes​​
Advanced manufacturing systems can break through traditional size limitations:

• ​​Ultra wide screen body​ ​: The width of a single box is up to 1.5 meters, horizontal splicing accuracy ±0.02mm
• ​​Micro module​ ​: Minimum customizable 50×50mm unit, supporting complex curved surface shape
• ​​Special shape splicing​ ​: Support non-standard units such as triangles/hexagons, with splicing angle error ≤0.1°

The wavy LED art installation adopted by a certain science and technology innovation center achieves pixel-level alignment on a three-dimensional structure with a curved surface radius of 3 meters through splicing 1,326 irregular units. This flexible display solution maintains display integrity while integrating architectural aesthetics.

The essence of choosing LED size is to balance display effects and spatial characteristics. With the maturity of modular technology, size has changed from restrictive conditions to creative expression tools. In specific projects, it is recommended to adopt the dual-factor verification method of "spatial scanning + content simulation" to rehearse the actual effect through 3D modeling, which is more practical than simply pursuing parameters.
