What is your MOQ and lead time for energysaving LED display and indoor LED poster screen?

Step 1: Premium Raw Material Selection & Int'l Partnerships

We have an annual production capacity of more than 15,000 square meters of LED displays. Only high-grade raw materials are used to ensure stable performance and excellent quality. We work closely with leading global suppliers such as Nationstar, Meanwell, ChipOne for chips, power supplies, ICs and 1.6mm PCBs.

Step 2: LED Chip High-Temperature Baking Before SMT Assembly

Before SMT Assembly,LED chips undergo 72-hour baking at 100℃ to keep them dry, effectively reducing the defect rate in the subsequent SMT assembly stage.

Step 3: SMT Assembly – Curing & AI Defect Inspection

During SMT assembly, LED chips and ICs are cured via high-temperature baking. AI-equipped equipment is used to inspect defect rates and screen out defective products, ensuring assembly precision.

Step 4: 2nd Defect Screening Before Module Assembly

After completing the SMT assembly process, a second round of defect screening is conducted prior to module mask assembly, achieving the pursuit of excellence in quality control.

Step 5: Module Light-Emitting Angle Inspection & Judgment

After module mask assembly, modules are placed on the aging test rack to check for uneven brightness (light/dark areas) and verify consistency of light-emitting angles (120-160°, refer to parameter sheet). Consistent angles allow progression to module aging tests; inconsistent angles trigger full-batch re-production.

Step 6: 6th Defect Screening During Module Aging Test

The 6th round of defect screening is performed during the module aging test. We only select modules that have passed all 6 previous inspections, strictly controlling product quality.

Step 7: 7th Quality Aging Test (48h) After Final Assembly

Qualified modules are transferred to the assembly workshop. After final assembly, the 7th quality aging test is conducted, lasting 48 hours. These 7 rounds of quality checks ensure flawless LED display quality.
