When investing in an LED display, whether for advertising, events, or commercial environments, choosing the right supplier is just as important as choosing the right product. Asking the right questions helps you avoid poor-quality screens, hidden costs, and compatibility issues that can damage your project’s success and ROI.

Here are five essential questions you should ask your LED screen supplier before placing an order:
Pixel pitch—the distance between the centers of two adjacent LEDs—directly affects resolution and optimal viewing distance. A smaller pitch (like P1.5 or P2.0) provides higher resolution, ideal for close-range indoor applications, while larger pitches (P4, P6, P10) suit large outdoor screens viewed from afar.
Ask your supplier:
“What pixel pitch do you recommend based on my screen size and viewing distance?”

The quality of the display heavily depends on the driver ICs and LED chips. High-performance ICs help deliver better refresh rates, grayscale, and stability. Reputable chip brands offer superior brightness consistency, long lifespan, and lower dead-pixel rates.
Ask your supplier:
“Which IC and LED brands do you use, and what are their performance ratings?”
Uniformity issues—like color shifts and brightness discrepancies—can ruin the visual appeal of a screen. Leading suppliers conduct multi-phase calibration and use high-binning LEDs to ensure consistent color across the screen.
Ask your supplier:
“Do you use automatic calibration and color correction processes?”
Energy efficiency is crucial, especially for large-scale or 24/7 LED displays. Ask if the product features common cathode designs, efficient power supply units, or low-heat emission modules that can reduce energy costs by 20%–40%.
Ask your supplier:
“Is your display system optimized for energy savings? What power efficiency can I expect?”
Even high-end LED displays can encounter technical problems. Ensure your supplier offers a reliable warranty, clear return policy, and responsive after-sales support—especially if you’re working internationally.
Ask your supplier:
“How long is the warranty period, and what’s included in the support package?”
