T/SLDA 01-2022 General Technical Specifications for Mini LED Commercial Displays

Scope

Scope: This document specifies the terms and definitions, classification, technical requirements, test methods, and inspection rules for Mini LED commercial displays, as well as requirements for marking, packaging, transportation, and storage. Main technical content: This document applies to commercial displays using Mini LED technology. It standardizes various technical requirements for Mini LED commercial displays, including display classification, technical requirements (appearance and structure, basic functions, interface requirements, and performance). Basic functions mainly include the functional elements that a Mini LED indoor commercial display should possess after assembly, such as supported operating systems, parameter settings, frame rate settings, connection methods, Gamma settings, optical parameter settings, communication interfaces, etc. The main performance of Mini LED commercial displays mainly includes ink color consistency (surface color difference), structural assembly accuracy, maximum brightness, brightness viewing angle, chromaticity viewing angle, brightness uniformity, color coordinate deviation, primary color wavelength error, color gamut overlap, maximum contrast ratio, electrical requirements (grayscale levels, frame refresh rate, refresh rate), energy efficiency (average power efficiency, power factor, energy efficiency level), pixel failure rate, safety requirements, electromagnetic compatibility, mechanical adaptability, environmental adaptability, and average failure-free operating time. This document standardizes the test methods and inspection rules for various technical requirements of Mini LED commercial displays.
