Full color LED display is a kind of LED display, the current market in all areas have their presence, the application is very extensive. This article on the full color LED display supporting product selection to explore, to help industry users a more comprehensive understanding of full color LED display.
1.LED lights and chips
LED lights are both LED tube, it is the key device LED electronic display so the use of reliable quality, packaging mature LED products. Select the LED network products must have good stability, small dispersion, HBM greater than 4000V, attenuation of small pressure ability, brightness, wavelength, high angle consistency, good light distribution and can withstand temperature, moisture and ultraviolet Claim.
2. box
The overall use of steel or aluminum, using the door structure. The top of the box with a pin and the bottom of the use of guide sleeve to ensure accurate positioning between the box. The overall protection of the enclosure in line with IP65 standards, the other structure to fully consider the cooling problem.
3. Switching power supply
Display power supply through the certification of the famous brand switching power supply module, all the switching power supply have been rigorous testing, screening, aging. To ensure full compliance with international safety and quality certification requirements to meet the long-term stable and reliable display requirements. Under rated working conditions. To ensure that the service life of more than 10 years.
4. connector
The connector is an important connection device in the system. Should use high-quality connector products to ensure that the connector of the pure gold coating thickness, to maintain the best electrical connection performance. To ensure that the system in high temperature, high humidity environment, good electrical connection performance, the system can make long-term stable and reliable operation.
5. circuit board
The circuit board adopts flame retardant epoxy board, the design layout is reasonable, the wiring specification, meet the electromagnetic compatibility and the circuit stability request. Processing manufacturers should choose well-known manufacturers of products.
6. Driver chip IC device
Drive circuit using the international famous brand of constant current driver chip. In the large temperature range, to maintain high precision constant current output and high reliability, can make the display uniformity and reliability significantly improved. Display system main material should be CE, FCC, UL, CCC, ISO9000 certification. I believe that if done as mentioned above, adhere to the 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 LED display.
Conclusion:
Huge market potential to attract more and more manufacturers to join, the corresponding, the market more and more complex products, for industry users, a comprehensive understanding of LED display products related to knowledge, you can in a large extent On the avoidance of a little knowledge caused by improper purchase, to ensure that their investment utilization to maximize.
