Due to the innovation of technology and the upgrading of equipment, LED display has gradually replaced traditional advertising tools, showing vigorous vitality. We can see its presence in every aspect of our lives. As the saying goes, a good horse is equipped with a good saddle. If you choose a satisfactory LED display, you should also seriously consider the accessories of the LED display. The following are some suggestions and analysis of the selection of LED display accessories. It can help users to have a more in-depth understanding of the LED display.
1. LED lights and chips
The LED lamp is not only an LED light-emitting tube, but also a key component of the LED electronic display, so 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, small attenuation amplitude, strong withstand voltage, high brightness, wavelength, and angle consistency, good light distribution effect, and resistance to temperature difference, humidity and ultraviolet rays. .
2. cabinet
The box used in the selection of LED display accessories is generally made of steel or aluminum as a whole. The overall protection of the box body conforms to the IP65 standard, and the structure should fully consider the heat dissipation problem.
3. Switching power supply
The power supply of the display screen adopts the certified switching power supply module of the famous brand, so the switching power supply in the selected LED display accessories must undergo strict testing, screening and aging. Ensure that it fully meets the requirements of international safety and quality certification to meet the requirements of long-term stable and reliable operation of the display screen. under rated operating conditions. Ensure the service life is more than 10 years.
4. Connectors
The connector is an important connecting device in the system and 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 good electrical connection performance of the system under high temperature and high humidity environment, the system can run stably and reliably for a long time.
5. Circuit board
The circuit board is made of flame retardant epoxy material, with reasonable design and layout, and the wiring is standardized to meet the requirements of electromagnetic compatibility and circuit stability. Processing manufacturers should choose products produced by well-known manufacturers.
6. Driver IC device
When purchasing LED display accessories driver chip ic device, the driver circuit should choose the constant current driver chip of international famous brand. In a wide 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 be certified by CE, FCC, UL, CCC, ISO9000, etc. I believe that if the above mentioned, adhere to reliable supporting facilities materials and professional R & D design technology, will be able to reduce the failure rate of the display, and will greatly improve the reliability and stability of the LED display.
