Due to technological innovations and equipment upgrades, led displays have slowly replaced traditional advertising tools, showing a vibrant vitality. In all aspects of our lives, we can all see the appearance of their figure. The saying goes, a good horse with a good saddle, choose a satisfactory led display screen, but also seriously considered in the LED display parts and materials, the following is a small series finishing in the purchase LED display several suggestions accessories analysis, hope Can help users to understand LED display more deeply.
1. LED lights and chips
Led lamp is not only LED lighting tube, it is the key component of LED electronic display , so it is necessary to use reliable quality and packaged mature LED products . The selected LED products must have good stability, small dispersion, HBM greater than 4000V, low attenuation amplitude, high voltage resistance, brightness, wavelength, high angle consistency, good light distribution, and can withstand temperature differences, humidity and UV requirements. .
2. Cabinet
The cabinet used in the selection of LED display accessories is generally made of steel or aluminum. The overall protection of the cabinet complies with the IP65 standard, and the structure must fully consider the heat dissipation problem.
3. Switching power supply
The display power supply adopts the famous brand switching power supply module that has passed the certification, so the switching power supply of the selected LED display accessories must undergo strict testing, screening and aging. Ensure full compliance with international safety and quality certification requirements to meet the long-term stability and reliability of the display. Under rated operating conditions. Ensure that the service life is greater than 10 years.
4. Connector
The connector is an important connecting device in the system and one of the important accessories for 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. Ensure the system's good electrical connection performance under high temperature and high humidity environment, which can make the system run stably and reliably for a long time.
5. Circuit board
The circuit board is made of flame-retardant epoxy sheet, with reasonable design layout and trace specification to meet the requirements of electromagnetic compatibility and circuit stability. Processing manufacturers should choose products produced by well-known manufacturers.
6. Driver chip IC device
When purchasing the LED display accessory driver chip IC device, the driver circuit should use the international famous brand constant current driver chip. Maintaining high-precision constant current output and high reliability over a wide temperature range results in significant improvements in display uniformity and reliability. The main materials of the display system should be certified by CE, FCC, UL, CCC, ISO9000, etc. It is believed that if we do the above, adhering to reliable supporting facilities materials and professional R&D design technology will definitely reduce the failure rate of the display and greatly improve the reliability and stability of the LED display.
Conclusion:
The broad market of led full color display is gradually attracting more LED display manufacturers to join the competition, and the LED display accessories products on the market are also various. Xiaobian hereby reminds users in this complex environment that we only have a more comprehensive understanding of LED display accessories to avoid the economic loss caused by improper purchase, so as to ensure that our investment is maximized.

The Din-Rail Terminal Block is used to facilitate the connection of wires. In fact, it is a piece of metal sheet sealed in insulating plastic. There are holes at both ends to insert wires and screws to fasten or loosen them. For example, two wires sometimes need to be connected and sometimes need to be disconnected. This can be connected with terminals and can be disconnected at any time without them It's very convenient and fast to weld or wind together. And it is suitable for a large number of wire interconnection. In the power industry, there are special Terminal Blocks, terminal boxes, all of which are terminal blocks, single-layer, double-layer, current, voltage, common, breakable, etc. A certain crimping area is to ensure reliable contact and enough current.
Insulation material is nylon 66 with good flexibility and flame retardant , copper alloy with wire frame structure provide moisture, salt fog and bad environment protection for a long time, special wire pressing structure have good self-locking and loose proof performance. the product designed in accordance with IEC60947.
