With the rapid development of the optoelectronics industry and its growing recognition in society, LED display products and technologies, as visual media for human-machine information transmission, have experienced swift growth. With the formation of product standard systems and the implementation of a series of standards, the LED display screen industry is moving towards a healthier and more orderly direction. LED display screens represent a currently lucrative market, finding wide application not only in large sports venues but also in highway toll booths, road signboards, airport flight information displays, docks, ports, train stations, tunnels, arcade games, urban square outdoor advertising boards, government office buildings, and parking lots for real-time display of dynamic information.
Traditionally, due to manufacturing processes and other reasons, there are significant differences in the characteristics of LEDs. When these LEDs are integrated into display modules to form LED display screens, if these differences are not adequately compensated for, it can lead to clearly visible differences in the brightness and color of the LED electronic display screens. Additionally, after being installed and used for some time, the brightness and color of the LEDs will degrade over time, but the degree of degradation varies for each LED, which can result in a decline in the visual quality of the LED display screens. Furthermore, the replacement of damaged LED modules during use can cause mismatches with the rest of the screen, further reducing the visual quality of the LED display screens.
The production and manufacturing of LED display screens occur in large quantities; in Shenzhen alone, there are hundreds of small and medium-sized LED display enterprises. Their technology is relatively mature, such as that of Shenzhen Lianchengfa Technology Co., Ltd. The structure and principle of the displays produced by various companies are basically similar in terms of LED display prices. How to enhance the technical performance of the displays and reduce costs is the key to competition among companies. Currently, the prices of LED display screens on the market are generally similar, but the quality of the displays produced by different companies varies, for reasons including differences in the quality, brightness, and brightness uniformity of the LED display modules, differences in encapsulation and other technologies, differences in data communication transmission methods and interference resistance capabilities, as well as differences in control circuits. Calibration technology for LED display screens can effectively help companies solve these problems. An increasing number of companies are adopting LED display calibration technology. As the demand for high-quality displays in the industry grows, point-by-point calibration technology for LED displays will be vigorously promoted and ultimately become one of the key technologies ensuring quality.
