LED display screens will have different degrees of blur and mosaic after using for a period of time. This is caused by the different attenuation curves of LED lights, and the point-by-point correction technology can effectively adjust the brightness of different light points of the LED display to the same Level, let the LED display screen return to the perfect display effect, we can also turn this process into a refurbishment of the old LED display screen.
Here we choose an LED display that has been used for more than 5 years to refurbish, first repair the broken modules and blind spots, and then use ultra-high-precision point-by-point calibration equipment to collect the brightness data of the LED display, and then use the The point correction software analyzes and processes the brightness data, and finally writes the corrected data into the control system.
After this series of processes, the original chromatic aberration is very serious, and the "dirty" LED display instantly becomes very beautiful, as if you have bought a brand new LED display. Are you surprised? Many LED display users do not understand the point-by-point correction technology, which leads to many LED displays that can be used are laid off in advance. No matter whether the LED display screen is scrapped or recycled, huge investment is required, and the emergence of point-by-point correction technology , It happens to allow the majority of LED display users to achieve a meager investment, high returns, and the calibrated LED display can continue to be used, which is also a measure to practice low carbon and environmental protection.
Why does the LED display need to be refurbished?
Due to the characteristics of LED light-emitting chips and the manufacturing process, the uniformity of LED screens has always been a problem that is difficult to solve in the industry; moreover, due to the discrete type of chip aging, many of them have been used for two, three years, or even half a year. The LED display shows serious spots, color blocks, mosaics and other "fuzzy" phenomena.
What kind of LED display can be refurbished?
Of course, not all LED screens can be refurbished by point-by-point correction. For example, large areas of dead lights, power failures and other problems caused the screen to fail to light up normally. If you encounter those problems, you must first fix all the fault points. Only then can the old screen be refurbished.
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 kept in an optimal state, and then you can start to do point-by-point calibration. Point-by-point calibration is the use of optical instruments to collect the brightness (or chromaticity) data of each lamp of the LED display, scientific analysis and calculation through the calibration software, and write the corrected data into the control system to achieve the brightness of the LED display (Chromaticity) The process of unification.
The calibrated LED display can maintain a brightness difference of 3%, and the chromaticity difference is within 0.003. The calibrated 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.
