Before purchasing an LED panel, it’s essential to evaluate several technical and practical factors to ensure you're making a smart investment. First, pixel pitch—the distance between pixels—determines resolution. A smaller pitch (e.g., 1.2mm) offers higher clarity for close viewing, ideal for indoor displays. Second, consider brightness levels (measured in nits); indoor panels typically need 800–1,200 nits, while outdoor ones require 3,000–6,000+ for sunlight visibility.
Next, examine refresh rate (ideally 3,840Hz or higher) for smooth video playback. Viewing angle, contrast ratio, and color accuracy also impact visual performance. Make sure the panel meets your environmental needs: waterproofing (IP rating) for outdoor use, and fanless designs for silent indoor operation. Assess build quality—lightweight but durable materials ensure easy installation and transport.
Compatibility with control systems and signal inputs (HDMI, SDI, etc.) is also important. Additionally, look into power consumption and heat dissipation, which affect operational efficiency. Always ask for certifications like CE, FCC, or RoHS to ensure safety and compliance. Finally, check the supplier’s warranty, after-sales service, and reputation. Testing a demo unit, if possible, can help you make a confident, informed decision.
