A LED screen with a life span of more than 5 years, the screen is very flowery, will you directly scrap the screen? If your warehouse has some idle cabinets, but the area is not big enough, it is not easy to sell, you will How to deal with it? If you have bought different batches of rental boxes and put together the color difference, what should you do?


LED display screen will use different degrees of flower screen and mosaic phenomenon for a period of time. This is due to the different attenuation curves of LED lights. The point-by-point correction technology can effectively adjust the brightness of different lamp points of the LED display to the same level. Level, let the LED display return to perfect display, we can also turn this process into an old screen refurbished LED display.

Here we have selected a LED display that has been used for more than 5 years for refurbishment. Firstly, after repairing the bad modules and defects, the ultra-high precision point-by-point calibration device is used to collect the brightness data of the LED display. The point correction software analyzes the brightness data and finally writes the corrected data to the control system.

After this series of processes, the original color difference is very serious, the LED display instantly became very beautiful, as if you bought a brand new LED display, is it surprising? Many LED display users point-by-point correction technology The lack of understanding has led to the early release of many LED displays that can be used. No matter the scrapping or recycling of LED displays, huge investment is required. The emergence of point-by-point correction technology can happen to the majority of LED display users. The meager investment, high return, and calibrated LED display can continue to be used, which is also a measure of 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 lamp dot of the LED screen has always been a problem that is difficult to solve in the industry; and because of the discrete type of chip aging, etc., many of them are used for two, three, or even half a year. The LED display shows 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 refurbished by point-by-point correction. For example, the screen caused by problems such as large dead lights and power failures cannot be properly lit. If you encounter any problems, you must first fix the fault points. In order to achieve the old screen renovation.


How to renovate the LED display?

To renovate the old screen, you must first repair the fault point, clean the entire screen, ensure that the LED display is in an optimal state, and then you can start point-by-point calibration. Point-by-point calibration is the use of optical instruments to collect the brightness (or chromaticity) data of each LED of the LED display, scientific analysis and calculation by calibration software, and the corrected data is written into the control system to achieve the brightness of the LED display. (Chroma) a unified process.

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


LED display precautions after refurbishment

After all, it is refurbished. There is definitely no new quality. The life of the display screen will be affected after the renovation for a long time. The light decay is accelerated and the dead light rate is improved. Another important thing to note is that some bad merchants use the refurbished display to act as a new display.
