Is it true that the window led transparent screen has a lifespan of 100,000 hours?


LED transparent screens, like other electronic products, have a service life. Although the theoretical life of LED is 100,000 hours, it can work for more than 11 years in 24 hours a day, 365 days a year, but the actual situation is much different from the theoretical data. According to statistics, the life of LED transparent screens on the market is generally 4~8 Years, LED transparent screens that can be used for more than 8 years are already very good. Therefore, the life of the transparent LED screen is 100,000 hours, which can be achieved in an ideal state, and 50,000 hours of use in actual situations is not bad.

There are internal and external factors that affect the life of LED transparent screens. The internal factors include the performance of peripheral components, the performance of LED light-emitting devices, and the anti-fatigue performance of products; the internal factors include the working environment of LED transparent screens and so on.


1. Influence of peripheral components

In addition to LED light-emitting devices, LED transparent screens also use many other peripheral components, including circuit boards, plastic housings, switching power supplies, connectors, chassis, etc. Any problem with any component may lead to the life of the transparent screen. reduce. Therefore, the longest life of the transparent display screen is determined by the life of the key component with the shortest life. For example, LEDs, switching power supplies, and metal casings are all selected according to the 8-year standard, and the protective process performance of the circuit board can only support its work for 3 years. After 3 years, it will be damaged due to rust, so we can only get a piece for 3 years. Transparent screen for life.


2. The influence of fatigue resistance of products

The fatigue resistance of LED transparent screen products depends on the production process. The anti-fatigue performance of the modules produced by the poor three-proof treatment process is difficult to guarantee. When the temperature and humidity change, cracks will appear on the protective surface of the circuit board, resulting in a decrease in the protective performance.


Therefore, the production process of the LED transparent screen is also a key factor in determining the life of the transparent screen. The production processes involved in the production of transparent screens include: component storage and pretreatment process, furnace welding process, three-proof treatment process, waterproof sealing process, etc. The effectiveness of the process is related to the selection and ratio of materials, parameter control and the quality of operators. For most transparent LED screen manufacturers, the accumulation of experience is very important. A factory with many years of experience will control the production process more effectively. .


3. The influence of LED light-emitting device performance

LED lamp beads are the most critical and life-related components of transparent screens. For LED lamp beads, the following indicators are mainly: attenuation characteristics, waterproof and vapor permeability characteristics, and anti-ultraviolet performance. If the LED transparent screen manufacturer fails to evaluate the performance of the LED lamp bead, it will be applied to the transparent screen, which will lead to a large number of quality accidents and seriously affect the life of the LED transparent screen.


4. The influence of the work environment

Due to different uses, the working conditions of transparent screens vary widely. In terms of the environment, the indoor temperature difference is small, without the influence of rain, snow and ultraviolet rays; the outdoor temperature difference can reach up to 70 degrees, plus wind, sun and rain. The harsh environment will aggravate the aging of the transparent screen, and the working environment is an important factor affecting the life of the transparent screen.

The life of LED transparent screen is determined by many factors, but the end of life caused by many factors can be continuously extended by replacing parts (such as switching power supply). However, it is impossible for LEDs to be replaced in large quantities. Therefore, once the life of the LEDs ends, it means the end of the life of the transparent screen. In a certain sense, the life of the LED determines the life of the transparent screen.


We say that the life of the LED lamp bead determines the life of the transparent screen, but it does not mean that the life of the LED lamp bead is equal to the life of the transparent display. Since the transparent display screen is not working at full load all the time, the life span of the transparent screen should be 6 to 10 times the life span of the LED when the transparent screen is playing video programs normally. LEDs can have longer lifespans when working with small currents. Therefore, the life span of the transparent screen using this brand of LED lamp beads can reach about 50,000 hours.


How to make the transparent led window screen last longer?


From the procurement of raw materials to the standardization and standardization of the production and installation process, it will have a great impact on the service life of the LED display. The brand of electronic components such as lamp beads and IC, to the quality of switching power supply, these are the direct factors that affect the life of LED large screen. When we plan the project, we should specify the LED lamp beads with reliable quality, the switching power supply with good reputation, and the specific brands and models of other raw materials. In the production process, we should pay attention to anti-static measures, such as wearing electrostatic rings, wearing anti-static clothes, and choosing dust-free workshops and production lines to minimize the failure rate. Before leaving the factory, it is necessary to ensure the aging time as much as possible to achieve a 100% pass rate. During the transportation process, the product should be packaged well, and the fragile product should be marked on the outside of the package. If it is shipped by sea, it is necessary to take measures to prevent hydrochloric acid corrosion.


In addition, the daily maintenance of the LED transparent screen is also very important. Regularly clean the dust accumulated on the screen so as not to affect the heat dissipation function. When playing advertising content, try not to stay in all white, all green, etc. for a long time, so as not to cause current amplification, cable heating and other faults such as short circuit. When playing festivals at night, the brightness of the screen can be adjusted according to the ambient brightness, which not only saves energy, but also prolongs the service life of the LED display. It is recommended that you choose a large manufacturer with quality assurance when purchasing LED displays.
