High buy quality LED display three indicators do you know?
After several years of development, LED display technology is not only mature, but also widely used in the market. Whether it is indoors or outdoors, LED display applications are everywhere, increasingly becoming the darling of the display market.
In the LED display market, there are many brands, and there are thousands of LED display manufacturers on the Chinese market. In such a large number of LED display manufacturers, users are inevitably dazzled when they choose to purchase, and they do not know which one to choose, especially those with selective syndromes. Because customers do not know much about LED display screens, they are often judged by simple parameters and price factors. However, it is difficult to buy high-quality LED displays. The following Xiaobian gives you several tips on how to purchase high-quality LED displays.
First, LED imaging performance: The first key to affect 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 the imaging performance and lifetime. The size of the LED also affects the pixel pitch and is therefore a determinant of resolution and image quality. The efficiency of the LED affects the total power consumption, which affects the operating costs and the thermal management of the installation. The brightness and quality of LEDs during production can also change and be graded. Manufacturers often choose to use the LED, higher quality brands will usually choose high-quality LED components, which is the basis for creating high-quality LED display.
Second, the second key factor is: drive circuit. This affects the reliability, power, and image fidelity of the overall LED display.
There are many kinds of driving methods, and some of them are better than others. Again, LED display manufacturers can use external suppliers or internal R&D and many other methods, 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.
Third, the mechanical design: mechanical design and positioning and installation depth, which is essential for seamless imaging of multi-cell splicing.
The human eye is very sensitive to uneven gaps between cells, so it is important to keep the seams completely aligned and flush. If the unit module is too close, the human eye will feel light or white lines, and if the distance is too far, you will see black or black lines. For service reasons, the pre-maintenance of individual modules has become increasingly popular. This has also placed additional demands on the mechanical design of LED displays in order to provide pre-maintenance performance while ensuring accurate docking.
Summary: A high-quality LED display, from design, material selection to production and many other aspects, each link affects the overall performance of the product, the so-called details determine the success or failure, can not be neglected. Everyone in the purchase of LED display, in accordance with the above three indicators to test, you can buy a satisfactory high-quality products.
