1. LED lamp and chip
LED lamp is not only an LED light emitting tube, but also a key component of LED full-color display screen. Therefore, LED products with reliable quality and mature packaging should be adopted. The LED products selected must have good stability, small dispersion, HBM greater than 4000V, small attenuation amplitude, strong pressure resistance, high brightness, wavelength, angle consistency, good light distribution effect, and resistance to temperature difference, humidity and ultraviolet.
2. LED box
The box used in the selection of LED full-color display accessories is generally made of steel plate or aluminum. The overall protection of LED box shall conform to IP65 standard, and the heat dissipation shall be fully considered for the structure.
3. Switching power supply
The power supply of the display screen adopts the certified switch regulated power module of famous brand, so the switch power supply in the selected outdoor LED display accessories must be strictly tested, screened and aged. To ensure full compliance with international safety and quality certification requirements, so as to adapt to the long-term stability and reliability of the display screen. High quality connector products shall be used., To ensure the thickness of the pure gold coating of the connector and maintain the electrical connection performance. Ensure good electrical connection performance of the system under high temperature and high humidity environment, and make the system operate 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 standard wiring, meeting the requirements of electromagnetic compatibility and circuit stability. The processing manufacturer shall select the products produced by well-known manufacturers.
6. Driver IC device
When purchasing the LED display accessories driver IC devices, the driver circuit should select the internationally famous constant current driver 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 screen. The main materials of the display system shall be certified by CE, FCC, UL, CCC, ISO9000, etc. It is believed that if the above is achieved and reliable supporting facilities and materials and professional R&D and design technologies are adhered to, the failure rate of the display screen will be reduced, and the reliability and stability of the outdoor LED full-color display screen will be greatly improved.
