Usually, the theoretical life of LED display is 100,000 hours, it can work for more than 11 years according to 24 hours a day, 365 days a year, but the actual situation and theoretical data are much worse. According to statistics, the life expectancy of LED displays on the market is generally 6-8. In the year, the large LED screen that can be used for more than 10 years is very good, especially the outdoor LED display, the life is even shorter. If we notice some details of the LED display, it will bring unexpected results to our LED screen display. If LED displays have been sold for less than their average lifetime, how can we be assured that we are investing in quality display components?


There are three key factors to consider when search to select a high quality LED screen display:



The first key to overall performance is the individual LEDs. This is where the image is born, so the consistency, stability, and reliability of the individual LEDs is critical for image performance and long life. The size of the LED also governs the pitch of the pixels, which is the determining factor for resolution and thus image quality. The efficiency of the LED affects the total power consumption, which affects the cost of operating and the thermal considerations of the installation. LEDs also have variation in brightness and quality during the production process and are routinely sorted (binned). Manufacturers have a choice of LEDs and high-quality brands should be using the highest quality components.



Second to the LEDs themselves, how they are driven electronically is critical in overall reliability, power, and image fidelity. There are different drive methods, and some are much better than others overall. Again, manufacturers have a range of choices from external vendors and in-house development efforts which yield a wide variety of performance.



The mechanical design—especially as it relates to alignment and mounting depth —is critical for forming a seamless image with multiple blocks. The human eye is very discriminating when it comes to uneven gaps between blocks, so keeping the seams perfectly aligned and flush is critical. If the modules are too close, the eye will perceive light or white lines. If the modules are spaced too far, you will see dark or black lines. For service reasons, it is very desirable to have front serviceability of individual tiles. This places even more demands on the mechanical design to both maintain alignment and allow front servicing.

As you can see, it all comes down to design choices and manufacturing.


From the procurement of raw materials to the standardization and standardization of the production and installation process, the use of LED display screens will have a great impact. From the electronic components such as chips, lamp beads and driver IC to the quality of switching power supplies, these are direct factors affecting the life of LED large screens, but they are often ignored by purchasers. When planning the project, we should specify the quality of the reliable LED lamp beads, good reputation of switching power supply, and the specific brand and model of other raw materials.


A good chip is a basis for the stability of the lamp bead, and a high-quality light-emitting chip should be used as the core material. As the most critical component of the LED display, the lamp bead has high-quality requirements. For the stable use of the lamp bead, it must have the prerequisites of high reliability and high performance. High-quality lamp beads require high-temperature, high-humidity, high-temperature aging tests for each batch of products.


The driver IC is truly a "small body big role", anti-"caterpillar", eliminate hidden light, high refresh, high gray level, excellent low gray and white balance all rely on the driver IC to solve. The high-quality driver IC has the ultimate advantage in brightness, grayscale, contrast, high density, viewing angle, stability, color uniformity, color saturation, image edge detail, and smooth video effects.


The power supply is also very important. Because the power supply is under different temperature conditions, its working stability, output voltage value and load capacity will be different. Because it is responsible for logistics support, its support capability directly affects the screen. quality.


In addition, the LED display can receive signals normally and can not be separated from the LED display controller, which is divided into asynchronous and synchronous modes. The excellent controller can avoid the loss of the signal to the maximum, improve the consistency of the display, and the whole display does not have any color difference patches.


Of course, in the process of LED display production, we must pay attention to anti-static measures, such as wearing anti-static rings, wearing anti-static clothes, choosing a dust-free workshop and production line to minimize the failure rate. Before leaving the factory, it is necessary to ensure the aging time as much as possible, and the factory pass rate is 100%. In the transportation process, the product should be packed, and the packaging should be fragile. If it is shipping, it is necessary to prevent hydrochloric acid corrosion. In addition, the daily maintenance of the LED display 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 be in full white, full green, etc. for a long time, so as to avoid current amplification, cable heating, and short circuit failure. When playing a holiday at night, you can adjust the brightness of the screen according to the brightness of the environment, which not only saves energy but also prolongs the service life of the LED display.


When we are planning the project, you are thinking more than that. After purchasing the LED display, the most important thing is to "help her wear a coat", let the big screen switch to various contents as desired, and the content is in the staff's monitoring and control. What you need at this point is to choose a suitable video processor. In the HD era of LED display, the video processor not only carries a lot of work such as image processing and analysis, codec compression but also embeds a large number of intelligent analysis algorithms to analyze a large amount of high-definition data, which plays a more important role. Video processors also play an important role in the operation of LED displays.

It can be seen that when choosing a set of LED display systems, it is necessary to consider the long-term use, not only the price factor but also the quality and service life.
