Abstract: For end users, what are the indicators for purchasing large LED screens, what are the latest technologies for large electronic LED screens, and what is the future development direction of large LED screens. I believe that direct users and people in the industry who have the intention to buy will pay more attention to it. For consumers, buy a large LED screen that is out of date and lasting and will not be eliminated. For end users, what are the indicators for purchasing large LED screens? What are the latest technologies for LED electronic large screens? What is the development direction of the screen? I believe that direct users and people in the industry who have the intention to buy are more concerned. For consumers, buy a large LED screen that is outdated and long-lasting and will not be eliminated. How can industry insiders recommend LED screens like customers All have deep meaning. The consistency of LED large screens is the most concerned by LED screen manufacturers. High-end LED large screen manufacturers introduce point-by-point correction and chromaticity uniformity correction technology to make up for the defects of poor consistency of LED tubes. Consistency has strict requirements on parameters such as the brightness, wavelength, splitting ratio, eccentricity, card point consistency, light distribution and viewing angle of the led tube. Therefore, in-line elliptical lamp packaging should pay attention to brightness, wavelength, split ratio, viewing angle, and the same color at the same time. With the development of technology, LED large screens are more and more widely used in all aspects of life. Full-color LED displays have unparalleled advantages of other display products, such as bright colors, clear images, good stability, high brightness, Long life, LED modular design can design the size of the LED screen according to user needs, weather resistance can be used outdoors and other advantages. With the development of society, people need more information exchange. LED screens are widely used in advertising, stations, shopping malls, airports, banks, stadiums, securities industry, sports stadium events, public information, stage background and other fields. The LED large screen industry is in a stage of rapid growth. In particular, driven by favorable policies for energy conservation and emission reduction, led technology has continued to advance, and the market capacity has maintained an annual growth rate of 15%. High-end LED large screens have strict requirements on the specifications of one of the core components of the elliptical LED tube, such as the brightness, wavelength, light shape, RGB light distribution, attenuation, and failure rate of the tube. Parameters such as light distribution, RGB light distribution, eccentricity, stuck point consistency failure rate, etc. are indispensable. Stable process conditions and strict quality control system can ensure the provision of high-quality LED screen products. Brightness: R>1000mcd, G>2000mcd, B>500mcd; Wavelength: 3nm bins; Split ratio: 1:1.1; Viewing angle: 105±5° in the horizontal direction, 55±5° in the vertical direction; Light distribution: relative light of the same color The strong light distribution curve is controlled within 10%, and the RGB relative light intensity distribution curve is controlled within 10%; failure rate: less than three hundred thousandths. To meet such requirements, the quality and service life of the LED screen can be guaranteed, but in this way, the source material of the LED screen must be strictly controlled to ensure the quality of the LED lamp, in order to produce high-end LED screens.
