1. LED lamp beads and chips: LED lamp beads are not only LED light-emitting tubes, but also the key components of LED display screens, so LED products with reliable quality and mature packaging should be used. LED products must have good stability, low dispersion, HBM greater than 4000V, small attenuation, strong voltage resistance, high brightness, wavelength, and angle consistency, good light distribution, and resistance to temperature differences, humidity, and ultraviolet rays. 

2. Box body: The box body used in the selection of LED display accessories is generally made of steel plate or aluminum as a whole. The overall protection of the cabinet complies with the IP65 standard, and the structure should fully consider heat dissipation issues.

3. Switching power supply: The LED display uses a certified famous brand switching power supply module, so in the selection of LED display accessories, the switching power supply must undergo rigorous testing, screening and aging. Ensure full compliance with international safety and quality certification requirements to meet the long-term stable and reliable work requirements of the display.

1. The connector: the connector is an important connection device in the LED display system, and it 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. To ensure the system's good electrical connection performance under high temperature and high humidity environment, it can make the system run stably and reliably for a long time.

5. Circuit board: The circuit board is made of flame-retardant epoxy board, with reasonable design layout and standardized wiring to meet the requirements of electromagnetic compatibility and circuit stability. Processing factories should choose products produced by well-known manufacturers.

4. Drive chip IC device: when purchasing LED display accessories drive chip ic device, the drive circuit should choose the international famous brand constant current drive chip. In a large temperature range, maintaining high-precision constant current output and high reliability can significantly improve the uniformity and reliability of the display. The main materials of the display system should pass CE, FCC, UL, CCC, ISO9000 and other certifications. I believe that if we do what we said above, adhere to reliable supporting facilities materials and professional R&D and design technology, we will definitely be able to reduce the failure rate of the display, and will greatly improve the reliability and stability of the LED display.

Whether the LED display is good or not depends on the quality of the accessories. Combining the above points to choose LED display accessories, your LED display will run well and stable!
