Some important things to consider when purchasing full-color outdoor LED display system; There are also many types of full-color LED displays on the market. Only by having a more comprehensive understanding of LED display screen can avoid economic losses caused by improper purchase and ensure a return on your investment.
Here is an analysis of some tips by Doitvision when purchasing outdoor LED display. we hope it can help everyone.
LED beads and chips
LED beads are both LED light-emitting tubes and are key components of full-color LED displays. Therefore, reliable quality and mature LED packaging must be used. The used LEDs must have good stability, small dispersion, HBM greater than 4000V, small attenuation, strong voltage resistance, high consistency in brightness, wavelength and angle, good light distribution effect, and resistance to temperature differences, moisture and ultraviolet rays.
LED cabinet
When selecting full-color LED display system, the cabinet used is generally made of steel plate or aluminum. The overall protection of the LED display cabinet meets the IP65 standard, and the structure must fully consider heat dissipation issues.
Switching power supply
The LED display should be powered by a certified well-known brand-switching regulated power supply. Therefore, the power supply in the outdoor LED display must undergo strict testing, screening, and aging. Ensure full compliance with international safety and quality certification requirements to adapt to the long-term stable and reliable operation of the display. Under rated working conditions, the service life is guaranteed to be more than 5 years.
Connector
The connector is an important connecting device in the system and one of the important accessories of the full-color LED display. High-quality connectors should be used to ensure the thickness of the pure gold plating of the connector and maintain the electrical connection performance. Ensure the good electrical connection performance of the system in high temperature and high humidity environments, so that the LED display system can operate stably and reliably for a long time.
Circuit board
The PCB board is made of flame-retardant epoxy sheet, with reasonable design layout and standardized wiring to meet the requirements of electromagnetic compatibility and circuit stability. LED display manufacturers should choose high-quality PCBs produced by well-known PCB manufacturers.
Driver chip IC device
When you buy outdoor LED display, driver chip IC devices, the driver circuit should use constant current driver chips from internationally renowned brands. Maintaining high-precision constant current output and high reliability within a wide temperature range can significantly improve the uniformity and reliability of the display. The main materials of the LED display system should pass CE, FCC, UL, CCC, ISO9000 and other certifications.
