The service life of LED display screen is more than 100000 hours. Because the backlight is generally LED light, the service life of the backlight is similar to that of LED display screen. Even if it is used 24 hours a day, the equivalent life theory is more than 10 years.
LED lamp bead is the key and life related important component of LED display screen. As far as LED lamp beads are concerned, they mainly refer to the following indicators: attenuation characteristics, water vapor permeability resistance, UV resistance linearity. If the LED display manufacturer fails to pass the evaluation on the performance indicators of the LED display beads, a lot of quality accidents will occur to the LED display beads, which will seriously affect the service life of the LED display beads.
In the production process of LED display, anti-static measures must be taken. The generation of static electricity will greatly damage the LED lamp beads, which will greatly reduce the life of the LED display. For example, wear electrostatic rings, anti-static clothes, and choose dust-free workshops and production lines to minimize the failure rate. Before leaving the factory, the aging time shall be guaranteed as much as possible, and the factory pass rate shall be 100%. During the transportation, the product shall be well packaged, and the package shall be marked fragile. If it is transported by sea, anti hydrochloric acid corrosion measures shall be taken. Avoid damage to the screen due to errors during transportation, and reduce the service life.
The working environment is also one of the main factors affecting the service life of LED display. As far as the environment is concerned, the indoor temperature difference is small and is not affected by rain, snow and ultraviolet light; The outdoor temperature difference can reach 70 degrees, plus wind, sun and rain. The bad environment will aggravate the aging of LED display, and the working environment has a great impact on the service life of the display.
LED display screen needs to use many other supporting parts, such as: switching power supply, PCB, plastic shell, connector, housing, etc. Any quality problem of any part may lead to the reduction of screen life. Therefore, the life of the display screen is determined by the life of the key component with short life.
1. Provide stable power supply Stable power supply can provide stable voltage, which is not easy to cause local high temperature damage, and ensure the normal operation of LED panel.
2. The lamp bead is the key to affect the life of the LED film mounting screen. When planning the project, specific brands and models of reliable LED lamp beads, switching power supplies, and other raw materials should be specified.
3. Take heat dissipation as a central work from module design to project implementation and even future system maintenance; Reduce LED working current; Properly configure LEDs to make each primary color LED attenuate synchronously.
4. Outdoor LED panels have a rest time of more than 2 hours every day, and at least once a week in the rainy season. Turn on the screen at least once a month and light it up for more than 2 hours.
5. Regularly check whether the anti-corrosive and anti rust paint on the product surface and the steel structure welding joint falls off. If there is peeling or rust, please spray antirust paint or antirust paste in time.
6. To avoid touching the led panel, we can choose passive protection and active protection. When cleaning the screen, we should also wipe it as gently as possible to minimize the possibility of injury.
