1. The influence of product temperature on the life of the display

The long life time of any product during the service life can guarantee the lowest consumption. As an integrated electronic product, the LED display is mainly composed of a control board of electronic components, a switching power supply, and a light emitter. The life span is all related to the operating temperature. If the actual operating temperature exceeds the specified operating temperature range, the life of the display product will be greatly shortened, and the senior display product will be seriously damaged.

　　2. The impact of environmental dust on the life of display screen products

　　 In order to best extend the life of the LED display, the threat from dust must not be underestimated. When the display screen is used in a dusty environment, the printed board absorbs more dust, and the deposition of dust will also affect the heat dissipation of the electronic components, which will cause the temperature of the components to rise rapidly, and then the thermal stability will decrease. Even leakage occurs, which can cause burnout in severe cases. In addition, dust can also absorb moisture, corrode electronic circuits, and cause short-circuit failures. Although the volume of dust is small, the harm to the product cannot be underestimated. Therefore, it must be cleaned regularly to reduce the possibility of failure. When cleaning the dust inside the display, remember to disconnect the power supply, operate carefully and safely, and safety first

　　 3. The influence of humidity on product life

　　 Although many LED display products can display and work normally in a humid environment, humidity will still affect the service life of the display. The moist gas will enter the IC device through the packaging material and the joint surface of the components, causing the internal circuit to oxidize and corrode and open the circuit. The high temperature in the assembly welding process will cause the moist gas entering the IC to heat and expand and generate pressure, which will make the plastic from Internal separation (delamination) on the chip or lead frame, wire bonding damage, chip damage, internal cracks and cracks extending to the surface of the component, and even component swelling and bursting, also known as "popcorn", which will lead to assembly Parts are repaired or even scrapped. More importantly, those invisible and latent defects will be incorporated into the product, causing problems in the reliability of the product. Reliability improvement methods for humid environments include the use of moisture-proof materials, dehumidifiers, and protective coating covers.

　　4. The influence of corrosive gas on product life

　　Humidity and salty air environment can cause the degradation of system performance, because they will accelerate the corrosion effect of metal parts, but also beneficial to the production of primary batteries, especially when different types of metals are in contact. Another harmful effect of moisture and salty air is the formation of a film on the surface of non-metallic parts that causes the insulation and dielectric properties of these materials to deteriorate, thereby forming a leakage path. Moisture absorption by insulating materials can also increase the volume conductivity and dissipation factor of the material. Reliability improvement methods for humid and salty air environments include the use of air-tight seals, moisture-proof materials, dehumidifiers, protective coatings/caps, and reduction of the use of different types of metals.

　　 5. The influence of electromagnetic radiation on product life

　　 Radio frequency radiation interference to electronic systems generally comes from two sources. One way is that the electrical noise interference of the radiated field enters the system directly. Experiments show that when the field strength reaches 5V/m, the system will definitely make mistakes. Electromagnetic interference is enough to change the value of the CPU program counter PC, causing the microcomputer to "jump" out of the executing program by mistake, especially for small signal circuits. The memory cannot work normally when the field strength is 15V/m. Another way of radio frequency radiation interference is introduced through the power supply. The external power transmission line is equivalent to the receiving antenna, which introduces radiation interference into the system, which can burn the power supply of the system itself when the interference is serious.

　　 6. The impact of vibration on product life

　　Electronic equipment is often subjected to environmental shocks and vibrations during normal use and testing. When the mechanical stress caused by the generated deflection exceeds the allowable working stress of the component parts, this environment can cause physical damage to the components and structural parts.

The above is about the related factors that affect the life of the full-color LED display, and the related factors that must be paid attention to when selecting the LED display, and the relative popularity and credibility of the LED display manufacturer. Make sure you avoid being deceived to buy improper and shoddy products, and I hope users and friends can remember.
