[LED displays](https://www.sostron.com/product?category=2) that have been used for more than 5 years may have problems such as screen blur and mosaic, but this does not mean that they need to be scrapped directly. By adopting point-by-point correction technology, LED display screens can be effectively renovated. Here are the main steps in the renovation process:

1. Faulty modules and blind spot repairs:

First, repair the LED display with bad modules and blind spots. This may involve replacing a faulty module or repairing an individual LED light. [Take you 5 minutes to learn about LED display soft modules. ](https://sostron.com/news/806)

2. Point-by-point correction:

Utilize ultra-high-precision point-by-point correction equipment to collect brightness data of the LED display. The point-by-point correction software analyzes and processes the brightness data to ensure that the brightness of each LED light on the LED display is adjusted to the same level. This step is the key to restoring the LED display to perfect display effect. [How to adjust the brightness and contrast of LED display? ](https://www.sostron.com/service/faq/3422)

3. Write the corrected data into the control system:

After point-by-point correction, the corrected data is written into the control system of the LED display to ensure long-lasting uniform brightness and chromaticity.

Why do you need LED display refurbishment?

Due to the characteristics of LED light-emitting chips and manufacturing processes, the uniformity of light spots on LED screens has always been a difficult problem to solve. Coupled with chip aging, discreteness and other reasons, many LED displays have serious spots, color blocks, mosaics and other problems after being used for a period of time, so they need to be refurbished.

When to carry out LED display renovation?

Not all LED screens are suitable for renovation. Renovation is only effective when the LED screen has some minor problems, such as flower screen, mosaic, etc., and most of the LED lights can still work normally. For situations such as large-area dead lights, power failure, etc. that cause the entire screen to fail to light up normally, these fault points need to be resolved first.

Effects and precautions of LED display renovation:

Point-by-point correction technology can make the brightness difference of the refurbished LED display within 3% and the chromaticity difference within 0.003. The effect after renovation has been significantly improved, giving the LED display a new lease of life. However, the refurbishment process may result in a certain degree of brightness loss, depending on the quality of the LED display. When refurbishing, it is necessary to ensure that the screen is in optimal condition and that the brightness loss before and after point-by-point correction is controllable.

Through the renovation of point-by-point correction technology, the LED display screen can extend its service life, achieve the goal of low-carbon and environmental protection, and at the same time provide LED screen users with an economical and environmentally friendly choice.
