How should LED displays be categorized?

Types of LED Displays:LED displays are primarily distinguished by these three dimensions:

1. By Application Environment (The Core):

   • Outdoor: High brightness (>5000 nits), waterproof/dustproof (IP65+), heat resistant.
     
   • Indoor: Moderate brightness (800-1500 nits), high refresh rate, close viewing distance.
     
   • Semi-outdoor: Higher brightness, basic protection, often used for shop fronts.
     
   • 
     

2. By Packaging Technology (LED Chip Type):

   • SMD (Surface Mount Device): The industry standard; offers uniform color and wide viewing angles.
     
   • DIP (Dual In-line Package): Traditional tech; extremely high brightness, typically used for traffic lights.
     
   • COB (Chip On Board): Emerging tech; highly durable, better heat dissipation, used for micro-pitch screens.
     
   • 
     

3. By Cabinet/Structure:

   • Fixed Installation: Permanently mounted on walls or poles.
     
   • Rental: Lightweight, designed with quick-locks for easy assembly/disassembly.
     
   • Transparent: Grid design with high transparency, does not block the view.
     
   •
