        Theoretically the service life of the LED display is greater than 100000 hours, even if 24 hours a day without interruption, the equivalent life basically is more than 10 years, half-life is about 50,000 hours, how long the actual use of the product is closely related to the environment and maintenance. When customers purchase high quality LED display, also need to pay attention to the supplier's pre-sales and after-sales service, which can reduce the cost of maintenance later. Our company will provide a 3-year warranty, within the warranty period, customers have damaged modules can sent it back to our factory for free repair.

There are internal and external factors affecting the life of the LED display: internal factors include the performance of the LED lamp, the performance of peripheral components, the anti-fatigue performance of the product, and external factors include the working environment of the LED display.


LED lamps, the most critical and life-time related components of the display, for LED, we focus on the following indicators: attenuation characteristics, anti-vapor penetration characteristics, anti-UV performance. Brightness attenuation is the inherent characteristics of LED. For a design life of 5 years of the display, if the brightness of the LED used to decay 50% in 5 years, in the design should be considered to set aside a margin of decay, otherwise the display can not meet the standard after 5 years. Decay indicator stability is also important. If in 3 years, the decay has exceeded 50%, it means that the life of this screen come to end in advance. So when buying LED display, it is best to choose good quality LED lamps, our company cooperates with companies such as Nationstar, Kinglight and HongSheng, the quality of these lamps is guaranteed.

Outdoor displays are often subject to the erosion of moisture in the air, LED chips in contact with water vapor can cause stress changes or electrochemical reactions leading to device failure. In addition, under ultraviolet radiation, LED colloid, support material properties will change, leading to device cracking, which in turn affects the life of the LED. So the LED used in outdoor UV resistance is also one of the important indicators. So the outdoor LED display waterproof treatment must be done, the protection level should reach IP65 in order to achieve waterproof, dust proof, sun protection and other effects.

Not only LED chips, the display also uses many other peripheral component materials, including circuit boards, plastic housings, switching power supplies, connectors, enclosures, etc. Problems with any one component may lead to a reduction in the life of the display. So it is especially important to choose a good material. In addition, how fatigue resistance of the display product depends on the production process. Poor triple anti-treatment process to produce the module anti-fatigue performance is difficult to ensure, in the temperature and humidity changes, the circuit board protection surface will appear cracks, resulting in a decline in protection performance.

So, it is very important to maintain the display. Here is some ways to maintain the led display:


1.Check the fixity of the internal components of the LED display screen body. Damaged parts should be replaced in a timely manner. When receiving weather changes and other natural disasters warning, customers need to check the stability and security of the screen body components, if there are problems, need to fix the problems in time, so as to avoid unnecessary losses. Do maintenance of the LED display and steel structure welding point surface coating regularly, which can prevent corrosion rust and fall off. LED display needs at least 2 times a year maintenance.


2.The inspection of bad products: for bad products, we need to do regular inspection, repair or replacement, generally once every three months.


3.Clean the LED lamps in the process of LED display maintenance. When cleaning LED lamps, you can use a soft brush to scrub the dust accumulated outside the LED lamp gently. If it is a waterproof case, you can also dip a little water to do cleaning. According to the use of LED display environment, we need to clean LED display regularly can ensure the stable operation of the entire screen body.


4.Check the LED display lightning protection facilities frequently. Check the lightning rod and grounding lines regularly. It should be tested on the anti-tube after the occurrence of lightning. If thees devices are fail to using, must be replaced in time. Besides, it needs to be check during rainy periods.


5.Check the display screen power supply system. First step is to check the distribution box to see whether there is rust or loose in each connection of the line. In order to safety, the grounding of the electrical box must ensure normal, power lines and signal lines should be checked regularly to avoid the line broken or chewed. The whole power supply system also needs to be checked twice a year.


6.LED control system inspection. According to the various functions of pre-set situation, then test the control system. All the lines and equipment of the screen should be checked regularly, so as to avoid unexpected situations. Check the reliability of system regularly, e.g. every 7 days.


Any product has a life cycle, LED display also the same. The life of a product is not only related to the quality of its own raw materials, production process, but also closely related to customer’s daily maintenance. To extend the service life of the LED display, people must develop the habit of maintenance of the LED display in the process of use, so as to reduce losses and then it can be used with a longer time.

LED Display Aging Test LED Display Aging Test
May .28.2024
LED display aging test is a measure taken based on the characteristics of the product's failure rate curve, that is, the bathtub curve, in order to improve the reliability of the product. If there is a question about frequency, it is not constant current. AC or pulsating current sources can be designed to have a constant effective value, but such power sources cannot be called "constant current sources." Constant current aging is the most consistent with the working characteristics of LED current and is the most scientific LED aging method; over-current impact aging is also the latest aging method adopted by manufacturers. This type of aging is carried out by using a constant current source with adjustable frequency and adjustable current. , in order to determine the quality and life expectancy of LEDs in a short period of time, and to pick out many hidden dangers of LEDs that cannot be picked out by conventional aging. LED display screens can improve performance after aging and contribute to performance stability in later use. A constant current source means that the current is constant at any time.

Simply speaking, the LED display screen is composed of several display units (unit display panels or unit display boxes) that can be combined and spliced, plus a set of appropriate controllers (main control board or control system). Therefore, display panels (or unit boxes) of various specifications and controllers with different control technologies can form many kinds of LED displays to meet the needs of different environments and different display requirements.

The smaller the point density and the gradient of pixel density, the more information capacity can be supplemented per unit instantaneously, and the distance suitable for viewing is closer. On the contrary, the distance suitable for viewing is further away. We need to combine our allocation and reconstruction effects to make the selection. As for the LED display screen, the smaller the pixels, the better. This is inevitable!
