Three-layer, four-sided deformable LED mechanical screen

The most prominent features of LED mechanical screens are their dynamic appeal, space utilization efficiency, and unique expressiveness; their application scenarios can cover various fields such as commerce, retail, culture and entertainment, and sports.

I. Core structure and mechanical design

1. Layered and rotational mechanism

• Three-layer architecture: the display consists of three independently rotating mechanical modules, each capable of horizontal or vertical rotation along a central axis for 360-degree dynamic presentation.
• Four-sided display: each layer incorporates four independent display surfaces with 90-degree angles between adjacent faces, ensuring multi-angle visual coverage.

2. Mechanical transmission and stability

• Transmission coordination: a distributed drive system can be employed, consisting of multiple motors and precision gear sets, each layer independently controlled but requiring synchronized control.

• Increased stability challenges: inter-layer connection points and changes in the center of gravity during deformation introduce complex torques and vibrations, necessitating simulation optimization using finite element analysis.

• Control is crucial: a central controller is required to coordinate and manage all servo motors, deformation mechanisms, and display content; command issuance must achieve millisecond-level synchronization accuracy.

II. Display technology and performance parameters

1. Display surface features

• Curved stereoscopic design: arc-shaped surfaces enhance wide-angle viewing and minimize distortion. For example, multi-layer tower LED screens use curved panels for striking rotational effects.
  
• Fine-pitch LED modules: utilizes P2–P3 SMD three-in-one packaged LED chips, delivering high brightness and contrast (≥10,000:1).

2. Dynamic display capabilities

• Independent panel control: each surface can play videos, animations, or text independently, supporting synchronized or asynchronous switching. A three-layer, four-sided screen can display 12 independent visuals simultaneously, with complex effects programmed via software.
• High refresh rate: ≥3,840Hz refresh frequency eliminates motion blur and stuttering, ideal for high-speed content (e.g., sports events, advertisements).
  

3. Color and brightness adjustment

• Wide color gamut: covers ≥120% NTSC with a color deviation (ΔE) ≤0.9 for accurate reproduction.
• Smart brightness control: supports 0–100% stepless dimming to adapt to varying ambient lighting.
  

III. Control system and intelligent features

1. Automated control platform

• Siemens programmer: instructions are programmed via computer and converted into signals to drive servo motors, enabling precise rotation and deformation.
  
• Remote management: 4G/5G or Wi-Fi connectivity allows remote power control, speed adjustments, and content updates, reducing operational costs.
  

2. Content playback system

• Multimedia server: equipped with high-performance servers.
  
• Scene presets: pre-programmed light effects and motion trajectories enable quick switching between scenarios (e.g., festivals, daily advertisements).
  

3.Smart interaction extensions

• Interactive interfaces: supports touch, or mobile app control for enhanced audience engagement (e.g., exhibition displays).

IV. Application scenarios and case studies

1. Commercial advertising and branding

• Shopping mall atriums: three-layer, four-sided screens attract foot traffic with rotational visuals, such as a six-sided mall installation displaying brand ads across all layers.
  
• 4S car dealership:the combination of a rotating mechanical structure and an LED display screen plays exciting videos, increasing consumers' desire to buy.

2. Business exhibitions and technology expos

• Exhibitions: modular design enables rapid setup for touring events (e.g., auto shows, tech expos).
  

3. Public information dissemination

• Transportation hubs: airports and train stations deploy transformable screens for rotating flight/train schedules and advertisements, improving information delivery.
  
• Smart cities: combined with environmental sensors, screens display real-time weather or air quality data for public service.
