Advantages and precautions for use of small-pitch LED display

The small-pitch LED display has the characteristics of high refresh, high grayscale, high brightness utilization, no image retention, low power consumption, and low EMI. It is not reflective for indoor applications, and the display contrast is as high as 5000:1; it is lightweight and ultra-thin, High precision, small space for transportation and use, quiet and efficient heat dissipation. Small-pitch LED display products have a wider color gamut space and faster response speed than ordinary large LED screens, and can realize seamless splicing and modular maintenance of any size. The whole picture played is uniform in color, high-definition lifelike, no abnormal display such as sweat spots and bright lines that are common on ordinary screens, and the picture switching is soft and does not flicker, and the picture quality is very delicate, which is close to the playback effect of a TV. The contrast ratio of 5000:1 can show excellent blackness when the screen is black, and it is the best among similar products. The biggest competitiveness of indoor high-density and small-pitch LED displays lies in the complete seamlessness of the large screen and the natural and true display colors. At the same time, in terms of post-maintenance, the LED large screen already has a mature point-by-point calibration technology.

But this spring, compared to face-to-face cooperation negotiations in the exhibition hall, all advertisers and LCD purchasers had to find another way to negotiate this year’s market cooperation projects. All LCD companies in Shenzhen have a problem in survival in such a big environment. It is understood that due to the impact of the epidemic, sales staff of many companies keep product prices low in order to place orders, but do not consider whether the quality of product accessories is satisfactory, which added many unnecessary after-sales problems to buyers. In other words, while pursuing low prices, we also need to pay for the quality problems caused by low prices. We hope everyone chooses carefully.
