How to choose a full color LED display?

Page view
As the LED industry technology matures, LED products are now available everywhere. Among them, high-definition full-color LED display screens are widely used in advertisements outside shopping malls, indoor and outdoor sports arenas, airports and high-speed rail passenger information system displays, etc., which are widely favored by the public. The demand for LED displays has soared, and various manufacturers are scrambling to compete for sales. As a result, the quality and price of LED displays on the market are uneven and far apart, making buyers feel at a loss. How to choose a full-color LED display? Since 2009, Shanghai Sansi, the first in the “Top 10 Most Developed LED Display Enterprises in China”, has been rated as the “Top 10 Most Developed LED Display Enterprises in China” for 4 consecutive times. The following suggestions:
 
First, the picture quality of the full color LED display
 
One of the important qualities of a high-quality full-color LED display is the uniformity of brightness and wavelength of each color in each pixel unit. According to the principle of optical three-primary color, the real-time state of each pixel from the video signal source is composed of red, green and blue signals, which are processed by the system and transmitted to corresponding pixel units on the LED display screen to respectively drive corresponding The color of the LED enables the mapping of the video source signal on the LED display. Then, the interlaced scanning is used to convert the progressive scan to ensure the sharpness of the still picture and the moving picture, and remove the pulling phenomenon of the moving picture.
 
The high-quality full-color LED display can automatically adjust the brightness of the display according to the visual characteristics of the human eye under different ambient brightness conditions, and the color temperature of the display can also be automatically changed to make the human eye visually comfortable and decent.
 
Second, the stability of full color LED display
 
The stability of a full-color LED display depends on factors such as wind, feng shui, shock, and lightning protection. Many manufacturers in the market often overlook these links, and the full-color screens provided cannot withstand the wind and rain. Shanghai Sansi always pays attention to the guarantee of these links. Take the high-definition full-color LED display on the "Captain No. 6" of the Huangpu River. It has experienced years of wind and sun, rain erosion, and often withstand the test of hull vibration. It has been intact and has become the Shanghai Bund landscape. A great view in the middle.
 
Third, the life of full color LED display
 
The service life of LED displays is another performance indicator that most users care about. Maintaining the overall brightness uniformity of the screen and color consistency is the true standard for measuring the actual life of LED displays. Most LED displays have become extremely poor overall color consistency long before the brightness decays to half. To this end, it is recommended that users choose the LED large-screen brand, it is best to actually examine the visual effects of the similar products of the brand after several years of use, and have a correct judgment on the durability of the products.
