T/SLDA 022-2025 Assessment requirements for quality grading and forerunner — Mini LED displays for indoor commercial application

Scope

This document specifies the basic requirements, evaluation indicators, and requirements for the quality and enterprise standard level of Mini LED indoor commercial display products, as well as the evaluation methods, grade classification, and product quality grading. This document specifies the basic requirements, evaluation indicators, and requirements for the quality and enterprise standard level of Mini LED indoor commercial display products, as well as the evaluation methods, grade classification, and product quality grading. This document applies to the evaluation of the quality and enterprise standard level of Mini LED commercial display products with a supply voltage of 250V AC or lower. Relevant institutions can refer to it when conducting quality grading and enterprise standard level evaluations, as well as "Leader" product evaluations and related certifications. Relevant enterprises can also refer to this document when formulating enterprise standards. The evaluation index system for Mini LED commercial displays includes baseline indicators, core indicators, and innovative indicators, mainly including: - Baseline indicators include safety requirements, limits on toxic and harmful substances, harmonic current, and radio interference limits; - Core indicators include brightness uniformity, deviation of white field color coordinates, error of primary color wavelength, brightness viewing angle, color gamut coverage (BT.2020), energy efficiency, frame rate, visual refresh rate, and ink consistency; the core indicators are divided into three levels, including advanced level, average level, and benchmark level; - Innovative indicators are intelligent level, which can be divided into average level and advanced level. It is encouraged to add relevant innovative indicators related to product performance and consumer concerns in a timely manner according to the maturity of conditions.
