From Factory to Field: How One Korean Client Built Trust with Our LED Display Team

When it comes to LED displays, many clients are not just buying a screen—they are placing trust in a team they have never met.That is why, for one of our Korean clients, seeing was believing—and testing came first.

The Project Background

The client runs a professional rental business in Korea, serving outdoor shows, brand events, and seasonal festivals.After comparing multiple suppliers, they chose our GS series outdoor rental LED display, thanks to its:

Dual power and signal backup system

Outdoor-grade IP protection

Magnetic front maintenance (added upon request)

Proven stability under frequent setup and teardown

Total ordered screen size: 108 sqm led video display,102 sqm in 500×1000mm cabinets,6 sqm in 500×500mm cabinets,We also customized 1-in-12 flight cases to match their loading size and event turnover rate.

Before Mass Production: Samples + Full Material Check

Trust didn’t start at the order—it started before production.To ease the client’s concerns, we first built a full-size led display sample, using the exact configuration they planned to order.Then, they personally visited our factory to:

Inspect the sample cabinet, from frame coating to LED uniformity

Test magnetic module removal, signal port locking, and cabinet flatness

Verify all incoming materials, including power supplies, LED batches, cables, and even aviation case foam , Every detail was on the table—literally.The client even brought their own tools to measure parts. We welcomed it fully.

Final Inspection: Real Trust is Built Face-to-Face

Once mass production began, the client came back again—this time to inspect the first batch of finished cabinets. In our testing area, we ran:

Brightness + uniformity test

Signal backup demo via 4 RJ45 ports

Power load-sharing simulation (we unplugged a PSU on purpose)

Complete cabinet assembly & disassembly flow

Full aging test system check (72 hours, powered-on)

After two full days, the client told us:

“Now I feel 100% confident in your team and your led video wall

Real-World Use: Setup, Plug, Perform

After shipment, the screens were used immediately—starting with a regional exhibition, then multiple outdoor cultural events.No unexpected issues. Fast installation. Smooth operation. Strong color. Minimal maintenance.
