A full set of full-color LED electronic display product introduction

1. LED lights and chips

The LED lamp is not only an LED light-emitting tube, but also a key component of a full-color LED electronic display screen. Therefore, reliable quality and mature packaged LED products should be used. The selected LED product must have good stability, low dispersion, HBM greater than 4000V, small attenuation, strong voltage resistance, high brightness, wavelength, and angle consistency, good LED Light module distribution, and resistance to temperature differences, humidity and ultraviolet rays, etc. Claim.



2. Box body



The whole is made of steel plate or aluminum, and the door structure is adopted. The top of the box adopts pins and the bottom adopts a guide sleeve to ensure accurate positioning between the boxes. The overall protection of the cabinet conforms to the IP65 standard, and the structure should fully consider heat dissipation issues.



3. Switching power supply



The power supply of the display screen adopts the certified famous brand switching power supply module. All switching power supplies have undergone strict testing, screening and aging. Ensure full compliance with international safety and quality certification requirements to meet the requirements of long-term stable and reliable operation of the display. Under rated working conditions. Ensure that the service life is greater than 10 years.



4. Connectors



The connector is an important connecting device 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 that the system has good electrical connection performance in high temperature and high humidity environments, so that the system can 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 standardized wiring to meet the requirements of electromagnetic compatibility and circuit stability. Processing factories should choose products produced by well-known manufacturers.



6. Driver chip IC device



The driving circuit adopts the constant current driving chip of the international famous brand. 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. It is believed that if we do the above, we insist on reliable supporting facilities materials and professional Ru0026D and design technology, which will definitely reduce the failure rate of the display and greatly improve the reliability and stability of the LED display.
