How much do you know about the used led display?

1.?How is the second-hand led display produced?

First of all, the existence of a used led display is justified. Many customers and specific environments use second-hand led displays. It exists because customers have demand, and it cannot be said that second-hand led display is not good! Many customers may feel disgusted when they see second-hand led display screens. They are used by some excessive merchants to use second-hand led display screens as a new led display screen. This kind of situation is rare, not to mention that customers are not greedy for cheap, it is almost impossible to encounter such problems.

2.?Led lamp of second-hand led display

The service life of a new LED display is generally 5-10 years. This time is not short. During this period, many changes will occur, such as demolition and relocation. The new replacement will make the original LED display still in normal use. It has become a second-hand LED display. For example, a certainly led display has been used for 3 years. It is still normal to use it. After receiving the request for a large screen or high-definition screen, the original screen is either reinstalled elsewhere or turned into a second-hand led display. There are special recycling and resale in the market. In order to reduce costs, the original led display is used as a second-hand Selling led display to others is also the most suitable.

3.?Reconstruction of second-hand led display

LED displays with different chips will show different degrees of blur and mosaic after using for a period of time. Point-by-point correction technology can effectively adjust the brightness of different light points of the LED display. At the same level, let the LED display return to the perfect display effect, we can also transform this process into the transformation of the old LED display screen.

Here, we chose an LED display that has been in use for more than 3 years for transformation. First, after repairing the bad modules and blind spots, use ultra-high-precision point-by-point correction equipment to collect the brightness data of the LED display, then use the point correction software to analyze and process the brightness data, and finally write the corrected data into the control system.

After this series of processing, it seems to have bought a brand new LED display. Are you surprised? Many LED display users are using point-by-point correction technology.

Due to a lack of understanding, many led display screens were eliminated in advance. Regardless of whether the LED display is scrapped or recycled, a large amount of capital investment is required, and the emergence of point-by-point correction technology just allows most LED display users to achieve the goal of low investment and high return, and the corrected LED display can also Continue to use, this is also a measure to practice low-carbon environmental protection.

4.?Why does the LED display need to be refurbished?

Due to the characteristics and manufacturing process of LED light-emitting chips, the uniformity of the light spots of LED display screens has always been a problem that the industry is difficult to solve; more because of the aging of discrete chips, many have been used for two or three years, or even half a year. The LED display shows serious "flowering" phenomena such as spots, color blocks, and mosaics.

5.?What kind of LED display can be refurbished?

Of course, not all LED screens can be corrected point by point. For example, the screen cannot light up normally due to problems such as large-area failed lights and power failures. If you encounter these problems, you must first repair the point of failure. Only in this way can the old screen be refurbished.

Precautions after LED display transformation

After all, it is refurbished. After the long-term refurbishment of the led display in sunlight and sunlight, its service life will inevitably be affected, the light attenuation will accelerate, and the dead-light rate will increase.

6.?How to refurbish the LED display?

To refurbish the old screen, it is necessary to repair the fault point and clean the entire screen to ensure that the LED display is kept in the best condition, and then the correction can be started point by point. Point-by-point calibration means that the optical instrument collects the brightness (or chromaticity) data of each lamp of the LED display, performs scientific analysis and calculation through the correction software, and writes the corrected data into the control system to realize the brightness (chromaticity) of the LED display) Unified processing.

The calibrated LED display brightness difference can be maintained at 3%, and the chromaticity difference is within 0.003. The revised LED display can see obvious improvement effects, of course, it will also face a certain degree of brightness loss, which depends on whether the quality of the LED display disappears.
