1. Introduction For B2B clients (including project contractors, facility managers, and enterprise procurement teams), selecting a professional LED display requires a clear understanding of core technical parameters. These parameters directly determine the display effect, service life, and operational cost of the product. This document will detail the key technical indicators of LED displays and provide practical selection guidelines to help clients make informed decisions for their specific project scenarios. 2. Core Technical Parameters Explained 2.1 Pixel Pitch Pixel pitch refers to the distance between the centers of two adjacent LED pixels (measured in millimeters, mm). It is a key factor affecting display resolution and viewing distance: the smaller the pixel pitch, the higher the resolution, and the shorter the suitable

1. Introduction Proper installation and regular maintenance are essential to ensure the stable operation and extended service life of professional LED display systems. This technical document provides a step-by-step installation guide, routine maintenance procedures, and common troubleshooting solutions for B2B clients and on-site technical teams, helping to reduce operational risks and maintenance costs. 2. Pre-Installation Preparation Before installation, ensure the following conditions are met to avoid installation failures: • Site Inspection: Check the installation area (wall, ground, or ceiling) for load-bearing capacity—ensure it can support the weight of the LED display (indoor displays: 20-50kg/m²; outdoor displays: 50-100kg/m²). • Environmental Preparation: For indoor installations, ensure the temperature (10-35℃) and humidity (30%-70%) are within the recommended range; for outdoor installations, confirm the
