T/SLDA 007-2025 Mini LED displays for indoor commercial application

Scope

This document specifies the product composition, display screen classification, technical requirements, test methods, and inspection rules for Mini LED commercial displays. This document applies to indoor Mini LED commercial displays and does not apply to transparent LED displays. This document is based on the main content of T/SDLA 007—2022, and summarizes and organizes the standard technologies and product technologies of indoor Mini LED commercial displays in the past two years. The main changes are as follows: 1. Added "Product Composition"; 2. According to the requirements of GB/T 43770, added three classification methods: "Installation Method", "Usage Method", and "Pixel Center Distance"; 3. Optimized "Structure Assembly Precision"; 4. Modified the requirements for "Maximum Brightness"; 5. Adjusted "Color Gamut Coverage (BT.2020)" to "Color Gamut Convergence (BT.2020)"; 6. Increased the requirements for "Grayscale Levels"; 7. Deleted the requirements for "Energy Efficiency Grade" and added requirements for "Energy Efficiency"; 8. Added requirements for "Energy Saving", "Vibration", "Collision (Impact Resistance)", "Pixel Malfunction Rate", and "Power Supply". From the perspective of advanced technology and quality evaluation, this product standard technical system is constructed. The main contents of the revised standard include display screen classification, technical requirements (appearance and structure, basic functions, performance and interface requirements), and test methods. Among them: 1. Basic functions mainly include the functional elements that Mini LED indoor commercial displays should have after assembly, such as supported operating systems, parameter settings, frame rate settings, connection methods, Gamma settings, optical parameter settings, communication interfaces, etc. 2. Main performance mainly includes ink color consistency (surface color difference), structure assembly precision, maximum brightness, brightness v
