After more than ten years of hard work, the LED display industry has developed greatly, and the technology and quality levels have improved rapidly. The LED display industry has basically formed the basic framework of the standardization system, and enterprise standardization has also made great progress. Standardization has played an important role in regulating the market, improving the quality of industry products, and promoting the overall development of the industry. The inspection work of the industry has also promoted the technological progress and quality improvement of the industry. I believe that standards and testing work will get more and more attention. 1. The products of many enterprises have not been tested for environmental adaptability (6.9) in accordance with the requirements of the "General Specification for LED Display". Therefore, involving environmental working temperature, anti-vibration and other indicators, it is difficult to have sufficient proof that the product meets the requirements of the contract or bid, and the product quality is not guaranteed. 2. Enterprises in the industry do not pay enough attention to the safety requirements (6.4) in the "General Specifications for LED Display". Grounding, safety marking, ground leakage current, electric strength and temperature rise are very important to the safety and quality of the product. If it fails, it will cause personal injury or other catastrophic damage. According to the relevant national standards, such items are mandatory fatal defects. Once the unqualified items are detected, they are unqualified projects or products. 3. Many contracts or bids use non-standard terminology. The existing definitions and standards in "General Specifications for LED Display" and "Test Methods for LED Display" are not used. However, citing other related names and indicators cannot be detected correctly. In the case of the seller's market, the user makes an explanation that is not conducive to the manufacturer, thereby causing unnecessary trouble and controversy. 4. Items that are clearly tested or discriminated cannot currently be tested. The entrusted unit, especially the detection of the external display screen of the user, has high expectations. For example, the confirmation of the origin and quality of the light-emitting tube, the detection of the LED working current of the display, the evaluation of the video effect, the evaluation of the overall quality of the Henan LED display and the detection of the production process of the display , To be improved, and to be improved in future work. 5. The current LED full-color display testing work is generally carried out after installation and debugging, and part of the testing should be carried out in the production process and before the product leaves the factory, and should not be carried out after acceptance or delivery. 6. Industry standards lack reasonable and effective quality testing methods and qualification criteria. Since the display screen is composed of a large number of display units, taking into account the uncertainties on the spot, some local areas or some indicators of the display screen (especially the assembly accuracy) 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 should establish product standards and inspection rules for raw materials, components and display units, so that the maximum brightness of the display screen, viewing angle, primary color wavelength error and other indicators are guaranteed during the production process. 8. The enterprise shall establish a quality inspection agency and be equipped with corresponding quality inspection equipment. Some small enterprises do not have equipment and professionals who implement industry standards, resulting in a large difference between the third-party testing data and the contract requirements after product construction. 9. Enterprises should strengthen factory inspection. Increase factory inspection and pre-inspection before completion of the project. Through factory inspection and pre-completion before completion, you can correct unqualified items and make the final inspection of third parties or customers pass smoothly. 10. The industry association should establish a more professional testing team and be equipped with corresponding testing equipment, and train professional testing personnel to meet the testing requirements of the market and member units.
