Several factors affect the LED display of life

We all know that using a good chip, good materials, general LED display using life is not short, will be used at least two years or more. But in the course, often we encounter a variety of problems, especially for use in outdoor LED display, often suffering from wind and sun, and even more difficult climatic conditions. So there will inevitably be problems, such problems arise is bound to affect the life of LED full-color display. So exactly what factors will affect the life of the LED display it. In fact, nothing more than that there are two factors, internal and external two; there are internal performance LED light emitting device, the fatigue performance peripheral component performance, the product; external with LED display work environment. LED light-emitting devices, namely display uses LED lights, is the most critical and display the most relevant parts and life, for LED, we focus on the following indicators: attenuation characteristics, water vapor permeability, UV resistance. Light attenuation is an inherent characteristic of the LED. For a design life of five years of the display, if the use of LED brightness decay by 50% for 5 years, to be considered in the design of attenuation reserve margin, or five years after the display performance can not be achieved; attenuation stability indicators also It is important, if the attenuation at 3 years more than 50%, it means that this screen ahead of the end of life. So when buying LED display, the best choice for good quality chips, if Nichia or Cree, etc. These professional large LED chip manufacturers, not only good quality and good performance. Display is used outdoors often eroded by moisture in the air, LED light-emitting chip in the case of contact with water vapor can cause stress or an electrochemical reaction leading to device failure. Under normal circumstances, LED light-emitting chip is epoxy package from erosion, bad some of the design flaws in material or workmanship of the LED device sealing performance, water vapor can easily combine gap plane through the gap or epoxy pins and housing into the interior of the device, causing the device to fail, the industry called "dead lights." Also in the ultraviolet irradiation, colloids, scaffold nature LED will change, causing the device to crack, thereby affecting the life of the LED. LED UV resistance for outdoor use is also an important indicator so. So use the outdoor LED display water treatment must be good, to achieve IP65 degree of protection can be achieved only waterproof, dustproof, sunscreen and other effects. In addition to the LED light-emitting device, the display also uses many other peripheral component materials, including circuit boards, plastic case, power supply, connectors, chassis and other components to any problems could cause the display to life lower. So, if the longest life LED display that is determined by the life of key components of most short-lived, and in no way an exaggeration. So choose good material, it is particularly important. How anti-fatigue properties of display products, depending on the production process. Poor treatment process to produce three anti-fatigue properties of the module is difficult to guarantee, in the temperature and humidity changes, the board will protect the surface cracks, causing performance degradation protection. So buy LED display to consider large manufacturers, has many years of experience of a LED display manufacturer of the control of the production process will be more effective. Outdoor LED display has been one of the advantages of Zhenyuan photoelectric products, the most important factor is the Zhenyuan photoelectric technological aspects, especially in water treatment improvement, storage and pretreatment processes for components, furnace welding process, three anti-treatment process, sealing and crafts. The effectiveness of the process and materials selection and matching, parameter control and quality-related operator, experience a lot of experience. Moreover, because the different uses, the display operating conditions vary. In terms of the environment, indoor temperature difference is small, no snow and UV effect; outdoor temperature difference of up to 70 degrees, plus wind and rain. Harsh environment will exacerbate the aging of the display, the work environment is an important factor affecting the life of the display. Although there are many factors that affect the life of the LED display, but as long as the selected display manufacturers to buy, good material, during use, pay attention to care and maintenance, so do not worry about the life of the display.
