In today's society, with the continuous advancement of technology, the speed of product upgrading is faster than ever. As an LED display for electronic products , the speed of product update is faster than other products. In such an era of rapid update, how to choose LED display accessories, you know ? The following small series gives you a detailed explanation. First, LED lamp beads and chips: LED lamp beads are not only LED lighting tubes, it is the key device of LED display , so it is necessary to use LED products with reliable quality and mature packaging . LED products must have good stability, small dispersion, HBM greater than 4000V , small attenuation, strong pressure resistance, high brightness, wavelength, angle consistency, good light distribution and resistance to temperature differences, humidity and UV requirements . Second, the box: the box used in the selection of LED display accessories generally use steel or aluminum. The overall protection of the cabinet complies with the IP65 standard, and the structure must fully consider the heat dissipation problem. Third, the switching power supply: LED display power supply through the certification of the famous brand switching power supply module, so the choice of LED display accessories, switching power supply must undergo rigorous testing, screening, aging. Ensure full compliance with international safety and quality certification requirements to meet the long-term stable and reliable working requirements of the display. Fourth, the connector : Connector is an important connection device in the LED display system, and is also one of the important accessories of the LED display . 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. Circuit board: The circuit board is made of flame-retardant epoxy sheet, with reasonable design layout and trace specification to meet the requirements of electromagnetic compatibility and circuit stability. Processing manufacturers should choose products produced by well-known manufacturers. Sixth, the driver chip IC device: When purchasing the LED display device driver chip IC device, the driver circuit should use the 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 shall 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 . 　　 The LED display is good, the key is to look at the quality of the accessories. Combine the above points to choose LED display accessories, your LED display will run well and stable !
