T/SPEMF 0041-2022 Mini LED Indoor Commercial Display Panel

Scope

Scope: This document applies to indoor commercial displays using Mini LED technology; Main technical content: This document specifies the terms and definitions, basic technical requirements, test methods, and inspection rules for Mini LED commercial displays. This document is applicable to indoor displays using Mini LED direct display solutions. This document is based on the main content of T/SDLA 02—2022 and standardizes various technical requirements for indoor commercial displays, including display classification, basic technical requirements (appearance and structure, basic functions, performance, and interface requirements). Among them: Basic functions mainly include the functional elements that a Mini LED indoor commercial display should have after assembly, such as supported operating systems, parameter settings, frame rate settings, connection methods, Gamma settings, optical parameter settings, communication interfaces, etc. Performance requirements are first based on the technical indicators determined for Mini LED indoor commercial displays in the Shenzhen Standard Advancement Evaluation Rules, and some performance requirements are determined. The main performance of Mini LED indoor commercial displays mainly includes ink color consistency (surface color difference), structural assembly accuracy, maximum brightness, brightness viewing angle, chromaticity viewing angle, brightness uniformity, chromaticity 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 grade), safety requirements, and electromagnetic compatibility, etc.
