LED display industry standards are a series of technical requirements and specifications for the design, manufacturing, testing, packaging, transportation, storage and other aspects of LED display products.
These standards are designed to ensure that the performance, quality, safety and environmental protection of LED display products reach a certain level, so as to meet market demand and consumer expectations.
The following is an overview of some major aspects of LED display industry standards:
I. Overview of standard content
LED display industry standards usually include the following aspects:
1. Definition and classification: clarify the definition of LED display and classify it according to different characteristics (such as use environment, display color, display function, etc.).
2. Technical requirements: specify the technical requirements of LED display in terms of brightness, grayscale level, pixel center distance, flatness, viewing angle, primary color main wavelength error, contrast, refresh frequency, etc.
3. Inspection method: describe in detail how to perform various performance tests and inspections on LED display to ensure that it meets the technical requirements.
4. Inspection rules: specify the sampling method and judgment rules for inspection to ensure the accuracy and fairness of the inspection results.
5. Packaging, transportation, and storage: Specify the packaging method, transportation requirements, and storage conditions of LED display products to ensure that the products are not damaged during transportation and storage.
II. Specific standard examples
1. SJ/T 11141-2003 General Specifications for LED Displays:
- This is an earlier LED display industry standard that specifies the definition, classification, technical requirements, inspection methods, inspection rules, and packaging, transportation, and storage requirements of LED displays. This standard applies to LED display products and is the main technical basis for the design, manufacturing, testing, and normative reference documents of LED display products.
2. GB 21520-2023 "Display Energy Efficiency Limit Values and Energy Efficiency Grades":
- This is the first national mandatory energy efficiency standard in the LED display industry, which will be officially implemented on June 1, 2024. This standard applies to LED integrated display terminals that are powered by AC or DC, use light-emitting diodes (LEDs) as display methods, have a pixel pitch greater than 0.30mm and not greater than 2.60mm, and a maximum brightness of not more than 3000cd/㎡. The standard specifies the energy efficiency levels of LED all-in-one machines and high-performance LED all-in-one machines, which are divided into three levels, and specifies the corresponding energy efficiency requirements.
III. The role and significance of the standard
The formulation and implementation of LED display industry standards are of great significance for promoting technological progress in the industry, improving product quality, protecting consumer rights, and promoting energy conservation and emission reduction. Specifically:
1. Regulating market order: By formulating unified technical requirements and inspection rules, it is possible to effectively avoid disorderly competition and counterfeit and shoddy products in the market, and maintain market order and consumer rights.
2. Promoting technological progress: The formulation of standards is often based on the latest technologies and best practices in the industry, so it can guide companies to increase R&D investment and promote technological innovation and industrial upgrading.
3. Improving product quality: By stipulating strict technical requirements and inspection methods, it can ensure that LED display products reach a certain level in terms of performance, quality, safety, etc., and improve user satisfaction.
4. Promoting energy conservation and emission reduction: With the enhancement of environmental awareness and the increasing prominence of energy issues, the formulation of LED display industry standards has also paid more and more attention to the requirements of energy conservation and emission reduction, and promoted the industry to develop in the direction of greening and low carbonization.
To sum up, the LED display industry standard is an important foundation for ensuring the healthy development of the industry, promoting technological progress, improving product quality, and promoting energy conservation and emission reduction.
