In order to meet the needs of customers, manufacturers can only increase their efforts to make each step more elaborate and attentive in the production of LED display, and must design a more reliable and practical LED display. Based on the current development of domestic technology, for the reliability test of LED display industry standards, it is actually difficult to achieve the reliability requirement of MTBF not less than 10,000 hours, and it is even more difficult to meet the requirements of highly reliable LED display.
However, in order to have a highly reliable LED display, the LED display material must be greatly improved, and the design requirements must be stylish, reasonable, and advanced.
Below we will first explain in detail from the LED display product materials:
First, from the LED light tube:
LED light-emitting tube should achieve the following key:
1. Good stability and small dispersion.
2. The index is high, the attenuation is small, and the pressure resistance is strong.
3. High consistency of brightness, wavelength and angle.
4. Good light distribution effect: perfect light distribution curve.
5. Can resist temperature difference, humidity and ultraviolet rays, suitable for outdoor environment.
The second is on the cabinet:
The whole adopts steel plate or aluminum material, and adopts the door opening structure. Both heat dissipation measures and waterproof measures must be fully considered.
And on the connector:
This is also an important link device, and 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 under high temperature and high humidity environment, which can make the system run stably and reliably for a long time.
Then on the switching power supply:
The LED display power supply adopts the well-known certified switching power supply module. All switching power supplies have undergone rigorous stress testing and screening. Ensure long-term stability and reliability requirements.
Finally, on the circuit board and drive chip ic device:
For the circuit board, flame-retardant epoxy sheet should be used, the design layout is reasonable, the wiring specification is to meet the requirements of electromagnetic compatibility and circuit stability. In a large temperature range, maintaining a 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 and other certifications. The above complaint is the high reliability requirements that LED display screens have in product materials. Only in this way can LED display screens be more and more improved in quality to achieve customer satisfaction.
Should also choose good LED products from 5 points of appeal.
To meet the requirements of high reliability in LED display products, manufacturers need to spend more time and energy to develop in this area. I believe that the future LED display industry technology will become more and more sophisticated, development will Unlimited!
