How to choose the full-color LED display accessory product materials
The full-color LED display is a kind of LED display. It has its appearance in various fields of the market and is widely used. This article explores the choice of full-color LED display accessory products to help industry users understand the full-color LED display more comprehensively. 1. LED lights and chip LED lights are not only LED lighting tubes, but also the key components of LED electronic display screens. Therefore, it is necessary to use LED products with reliable quality and mature packaging. The selected LED products must have good stability, small dispersion, HBM greater than 4000V, low attenuation amplitude, high voltage resistance, brightness, wavelength, high angle consistency, good light distribution, and can withstand temperature differences, humidity and UV requirements. . 2. The whole body of the box is made of steel plate or aluminum, and the door opening structure is adopted. The top of the box is made of pins and the bottom is made of guide sleeves to ensure precise positioning between the boxes. The overall protection of the cabinet complies with the IP65 standard, and the structure must fully consider the heat dissipation problem. 3. Switching power supply display power supply adopts the famous brand switching power supply module that has passed the certification. All switching power supplies have undergone rigorous testing, screening and aging. Ensure full compliance with international safety and quality certification requirements to meet the long-term stability and reliability of the display. Under rated operating conditions. Ensure that the service life is greater than 10 years. 4. Connector connectors are important connecting devices in the system. High quality connector products should be used to ensure the thickness of the pure gold plating of the connector and maintain the best electrical connection performance. Ensure the system's good electrical connection performance under high temperature and high humidity environment, which can make the system run stably and reliably for a long time. 5. The circuit board circuit board adopts flame-retardant epoxy board, the design layout is reasonable, the wiring specification is met, and the requirements of electromagnetic compatibility and circuit stability are met. Processing manufacturers should choose products produced by well-known manufacturers. 6. Driver chip IC device driver circuit adopts international famous brand constant current driver chip. Maintaining high-precision constant current output and high reliability over a wide temperature range results in significant improvements in display uniformity and reliability. The main materials of the display system should be certified by CE, FCC, UL, CCC, ISO9000, etc. It is believed that if we do the above, adhering to reliable supporting facilities materials and professional R&D design technology will definitely reduce the failure rate of the display and greatly improve the reliability and stability of the LED display. Conclusion: The huge market potential has attracted more and more manufacturers to join, and correspondingly, the products on the market are more and more complicated. For the industry users, a comprehensive understanding of the related products of LED display products can be very To a large extent, avoid improper purchases due to a smattering of solutions, and ensure the maximum utilization of investment.
