In the LED display market, there are many brands, and there are thousands of LED display manufacturers in the Chinese market. Among so many LED display manufacturers, users can't help being a little dazzled when purchasing, and they don't know which one to choose, especially those customers with choice syndrome. Because customers do not know much about LED displays, they often judge from simple parameters and price factors when purchasing. However, it is difficult to buy a high-quality LED display. The following editor from Lianchengfa (http://www.lcf-led.cn/) will share with you some tips on how to buy a high-quality LED display.
1. LED imaging performance: The first key that affects the overall performance is a single LED. This is the basic unit that makes up the entire image, so the consistency, stability and reliability of each LED are critical to imaging performance and longevity. The size of the LED also affects the pixel pitch, which is a determinant of resolution and image quality. The efficiency of the LED affects the total power consumption, which has an impact on operating costs and thermal management of the installation. The brightness and quality of LEDs also vary during production and are graded. Manufacturers usually choose the LEDs used, and higher-quality brands usually choose high-quality LED components, which is also the basis for creating high-quality LED displays.
2.the drive circuit: The second key factor is the drive circuit of the LED, which will affect the reliability, power and image fidelity of the overall LED display. There are many ways to drive, and some are better than others. Third, LED display manufacturers can use various methods such as external suppliers or internal research and development, which will also cause differences in the performance of LED displays. Good circuit design is also one of the important indicators for screening high-quality LED displays.
3. Mechanical Design: Mechanical design is related to positioning and installation depth, which is crucial for seamless imaging of multi-unit splicing. The human eye is very sensitive to uneven gaps between cells, so it is important to keep the seams perfectly aligned and flush. If the unit modules are too close, the human eye will perceive light or white lines, and if they are too far away, they will see black or black lines. The growing popularity of front maintenance of individual modules for service reasons also places more demands on the mechanical design of LED displays to provide front maintenance performance while ensuring precise docking.
Summary: A high-quality LED display includes many links from design, material selection to production. Each link affects the overall performance of the product. The so-called details determine success or failure, and there is no room for negligence. When purchasing an LED display, you can test it according to the three major indicators mentioned above, and then you can buy a satisfactory high-quality product.
