What is the effect of a good-quality LED display? In order to meet the needs of customers, manufacturers can only increase their efforts to make LED display screens more meticulously and carefully to do each step, and must design more reliable and more practical LED display screens. Based on the current development of domestic technology, it is actually difficult to achieve the reliability requirement of MTBF not less than 10,000 hours for the reliability measurement test in the LED display industry standard, and it is even more difficult to meet the requirements of high-reliability LED display.

  However, in order to have a highly reliable LED display, the material of the LED display must be greatly improved, and the design requirements must also be fashionable, reasonable and advanced. Below we will start with a detailed description of the LED display product materials.

Let’s start with the LED light-emitting tube: LED light-emitting tube should realize the following key points:

1. Good stability and low dispersion.

2. The index is high, the attenuation range 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. It can resist temperature difference, humidity and ultraviolet rays and is suitable for outdoor environment.

The second is on the box body: the whole is made of steel or aluminum, and the door structure is adopted. It is necessary to fully consider both heat dissipation measures and waterproof measures.

And on the connector: This is also an important link device. 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 good electrical connection performance of the system under high temperature and high humidity environment, so that the system can run stably and reliably for a long time.

Then on the switching power supply: the LED display uses a certified famous brand switching power supply module. All switching power supplies have undergone strict stress testing and screening. Ensure long-term stability and reliability requirements.

Finally, it is on the circuit board and the driver chip ic device: the circuit board should be made of flame-retardant epoxy board, the design layout is reasonable, and the wiring is standardized to meet the requirements of electromagnetic compatibility and circuit stability. 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 and other certifications. The above complaint is the high reliability requirements of LED display screens in product materials. Only in this way can the quality of LED display screens become more and more improved in order to achieve customer satisfaction.
