Product Description
The LED spherical screen features its unique "full view design". Integrating art and technology perfectly, bringing an unprecedented visual feast and innovative experience.
1. Need for ultra-high precision structural design and manufacturing:
Geometric complexity: Accurately adapting flat LED modules to spherical surfaces is a huge challenge. The sphere requires extremely complex surface structure calculations to ensure that the installation angle and spacing of each module remain highly consistent in three-dimensional space, avoiding visual gaps and image distortion. This far exceeds the design difficulty of flat or simple curved screens.
Customized modules: It is usually necessary to customize a large number of non-standard shaped modules (such as triangles and hexagons), which are tightly and seamlessly spliced into spheres. The design, mold making, production, and quality control costs are extremely high, and the cycle is long. Manufacturers with this ability are scarce.
Structural stability and lightweighting: Giant spheres require strict control of overall weight while ensuring structural strength such as wind and earthquake resistance. Strict requirements are placed on skeleton materials (such as high-strength aluminum alloys and carbon fibers) and engineering design.
2. Complex image processing and correction techniques:
Nonlinear real-time correction: Spherical display requires extremely complex nonlinear geometric correction and pixel mapping of the input video signal to ensure that the image is not deformed or distorted when viewed from any angle outside the sphere. This requires powerful specialized image processing engines and unique algorithms.
Multi perspective consistency: Maintaining the synchronization, brightness, and color uniformity of the 360 ° view of the sphere is much more technically challenging than flat or single-sided display.
3. Strict heat dissipation and environmental adaptability:
Challenge of three-dimensional heat dissipation: The internal space of the sphere is sealed, the air convection is poor, and tens of thousands of high brightness LED beads concentrate on heating. Innovative design of three-dimensional heat dissipation ducts or liquid cooling systems is needed to ensure controllable temperature in the core area, prevent performance degradation and shortened lifespan.
All day protection: As a large outdoor device, it needs to achieve high-level waterproof, dustproof, UV resistant, and high and low temperature resistance. The sealing and protection design of the spherical shell is more complex than that of conventional screens.
