How to refurbish the old screen of the LED display?

An LED screen with a service life of more than 5 years, the screen picture is very flowery, 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, there is a color difference when put together, what should you do?

The LED display screen will appear blurred and mosaic phenomenon to varying degrees after a period of time. This is caused by the different attenuation curves of the LED lights. The point-by-point correction technology can effectively adjust the brightness of different light points of the LED display to the same level. Level, let the LED display return to the perfect display effect, we can also turn this process into the renovation of the old screen of the LED display.

Here we choose a LED display that has been used for more than 5 years for refurbishment. First, after repairing the bad modules and blind spots, we use ultra-high-precision point-by-point correction equipment to collect the brightness data of the LED display, and then use the The point calibration software analyzes and processes the brightness data, and finally writes the corrected data into the control system.

After this series of processes, it turns out that the color difference is very serious, and the “dirty” LED display becomes very beautiful in an instant, as if you bought a brand new LED display, aren’t you surprised? Many LED display users do not understand the point-by-point correction technology, which has led to the layoff of many LED displays that can still be used. , which happens to allow the majority of LED display users to achieve a meager investment, high returns, and the corrected LED display can continue to be used, which is also a measure to practice low-carbon environmental protection.

Why do LED displays need to be refurbished?

Due to the characteristics of the LED light-emitting chip and the manufacturing process, the uniformity of the light point of the LED screen has always been a difficult problem for the industry to solve; moreover, due to the discrete type of chip aging, many have been used for two, three years, or even half a year. The LED display shows serious “flowering” phenomena such as spots, color blocks, and mosaics.

What kind of LED display can be refurbished?

Of course, not all LED screens can be refurbished through point-by-point correction. For example, the screen cannot be lit normally due to problems such as large-area dead lights and power failures. If you encounter those problems, you must first repair the fault points. In order to realize the renovation of the old screen.

How to refurbish the LED display?

To refurbish the old screen, it is necessary to repair the fault point first, clean the entire screen to ensure that the LED display is in an optimal state, and then start to do point-by-point correction. Point-by-point correction is to use optical instruments to collect the brightness (or chromaticity) data of each lamp of the LED display, conduct scientific analysis and calculation through the correction software, and write the corrected data into the control system to achieve the brightness of the LED display. (chroma) The process of unification.

The corrected LED display can maintain a brightness difference of 3%, and the chromaticity difference is within 0.003. The corrected LED display can see obvious improvement effects, of course, it will also face a certain degree of brightness loss, which depends on The quality of the LED display.
