Pre-production – strict material selection and plan formulation

  • Material Selection: Strictly select high-consistency LED chips, high-temperature-resistant PCBs, high-refresh driver ICs, and other materials.
  • Product Planning: Based on customer requirements, define key parameters such as screen size, resolution, and brightness, and develop a personalized solution.
  • Detail Confirmation: Verify drawings, process standards, and BOM lists to avoid production errors and missing components.

During Production – Quality Control

  • SMT Placement: Fully automated placement + optical inspection, ensuring zero component offset and defect-free soldering.
  • Module Assembly: Strict BIN mixing for color calibration + gel sealing, ensuring display consistency and waterproof/dustproof capabilities.
  • Full Screen Assembly: High-precision cabinet calibration, achieving seamless splicing and flatness ≤ 0.5mm.

Post-production – Comprehensive Testing

  • Optical Performance Testing: Manual point-by-point inspection of brightness and chromaticity uniformity.
  • Aging Test: 72-hour high and low-temperature cycle testing (-20℃ ~ 50℃) to assess humidity and heat resistance.
  • Functional Stability Testing: Continuous full-load operation for 48 hours to check dead pixel rate.

Packaging And Shipping

  • Shockproof Packaging: Custom foam + wooden box protection/flight case, ensuring absolute shock resistance, compression resistance, and drop protection.
  • Environmental Protection: Moisture-proof film + desiccant packaging, completely eliminating concerns about component moisture or oxidation due to temperature and humidity changes.
