After more than ten years of hard work, the LED display industry has achieved great development, and the technology and quality level have improved rapidly. The LED display industry has basically formed the basic framework of the standardization system, and the enterprise standardization work has also made great progress. Standardization work has played an important role in regulating the market, improving the quality of industry products, and promoting the overall development of the industry. The testing of the industry has also promoted the technological advancement and quality improvement of the industry. I believe that standards and testing will receive more and more attention. 1. Many companies' products have not been tested for environmental adaptability (6.9) in accordance with the requirements of the General Specification for LED Display. Therefore, it is difficult to have sufficient evidence to indicate that the product meets the requirements of the contract or tender, and the quality of the product is not guaranteed. 2. Enterprises in the industry pay insufficient attention to the safety requirements (6.4) in the “General Specification for LED Displayâ€. Grounding, safety markings, ground leakage current, electrical strength and temperature rise are important to the safety and quality of the product. Failure to do so will result in personal injury or other catastrophic damage. Such projects are mandatory fatal defects in accordance with the relevant national standards. Once the unqualified test is a non-conforming project or product. 3. Many contracts or tenders refer to terms that are not standardized. There are no definitions and standards already in the "General Specifications for LED Displays" and "Test Methods for LED Displays". The reference to other related names and indicators results in the failure to detect correctly. In the case of the seller's market, the user is not conducive to the manufacturer's explanation, resulting in unnecessary trouble and controversy. 4. Items that are partially detected or identified are currently undetectable. The inspection of the commissioning unit, especially the display screen outside the user, places great expectations. For example, the confirmation of the origin and quality of the illuminating tube, the detection of the working current of the LED of the display screen, the evaluation of the video effect, the evaluation of the overall quality of the LED display in Henan, and the detection of the production process of the display screen, these items of interest to the user are currently unable to meet the requirements of the entrusting unit. , to be improved standards, to improve in the future work. 5. The current LED full-color display inspection work is generally carried out after installation and commissioning, and part of the inspection should be placed in the production process and before the product leaves the factory. It should not be placed after acceptance or delivery. 6. The industry standard lacks reasonable and effective quality testing methods and qualified judgment standards. Since the display screen is composed of a large number of display units, in view of the uncertain factors on the scene, local areas or some indicators (especially assembly accuracy) of the display screen may not meet the requirements. Therefore, it is necessary to introduce a reasonable sampling method to make the inspection rules of the display screen more reasonable and feasible. 7. The enterprise shall establish the enterprise standard of the product and the inspection rules of the raw materials, components and display unit, so that the maximum brightness, viewing angle and primary wavelength error of the display screen are guaranteed in the production process. 8. The enterprise shall establish a quality inspection agency and equip with corresponding quality inspection equipment. Some small enterprises do not have the implementation of industry-standard instruments and equipment and professionals, resulting in a large difference in third-party testing data and contract requirements after product construction. 9. Enterprises should strengthen factory inspection. Increase the factory inspection and pre-inspection before the completion of the project. Through the factory inspection and pre-inspection before completion, the unqualified items can be self-corrected, so that the third party or the customer can pass the final test smoothly. 10. Industry associations should establish more professional testing teams and equipped with corresponding testing equipment, and train professional testing personnel to meet the testing requirements of the market and member units.
