How to renovate the old LED display screen after using it for more than 5 years

An LED screen with a service life of more than 5 years is very expensive. Will you directly scrap this screen? If your warehouse has some idle boxes, but the area is not large enough to sell, what will you do? If you have bought different batches of rental boxes and there is a color difference when they are put together, what do you do?

The LED display screen will appear different degrees of flower screen and mosaic after being used for a period of time, which is caused by different attenuation curves of LED lamps. Through point-by-point correction technology, the brightness of different light points of LED display screen can be effectively adjusted to the same level, so as to restore the perfect display effect of LED display screen. We can also turn this process into the renovation of old LED display screen.
Here we choose an LED display screen that has been used for more than 5 years for renovation. First, after repairing the bad module and blind spots, we use the ultra-high-precision point by point correction equipment to collect the brightness data of the LED display screen, then use the point by point correction software to analyze and process the brightness data, and finally write the corrected data into the control system.
After this series of processes, the original color difference is very serious, and the “very dirty” LED display screen suddenly becomes very beautiful. It seems that you bought a brand-new LED display screen. Isn’t you surprised? Many LED display screen users do not understand the point-to-point correction technology, resulting in many usable LED display screens being laid off in advance. Whether the LED display screen is scrapped or recycled, it requires huge investment. The emergence of point-to-point correction technology happens to enable the majority of LED display screen users to achieve low investment and high return. The corrected LED display screen can continue to be used, This is also a measure to practice low-carbon and environmental protection.
Why does the LED display need to be refurbished?
Due to the characteristics and manufacturing technology of LED light-emitting chip, the uniformity of LED screen has always been a difficult problem in the industry; Moreover, due to the discrete type of chip aging, many LED displays that have been used for two or three years or even half a year show serious “flower screen” phenomena such as spots, color blocks and mosaics.
What kind of LED display can be refurbished?
Of course, not all LED screens can be renovated through point-to-point correction. For example, the screen cannot be lit normally due to problems such as large-area dead lights and power failure. If those problems are encountered, the fault points must be repaired first to realize the renovation of the old screen.
How to renovate the LED display?
To renovate the old screen, first repair the fault point and clean the whole screen to ensure that the LED display remains in a good state, and then you can start to make point-by-point correction. Point by point correction is the process of using optical instruments to collect the brightness (or chromaticity) data of each lamp of LED display screen, conduct scientific analysis and calculation through correction software, and write the corrected data into the control system to achieve the unity of brightness (chromaticity) of LED display screen.
The corrected LED display can maintain the brightness difference of 3% and the chromaticity difference is within 0.003. The corrected LED display can see obvious improvement effect. Of course, it will also face a certain degree of brightness loss, which depends on the quality of LED display.
