Three points for attention in purchasing small spacing LED display

The most competitive small pitch LED display screen in the market not only takes the lead in the industry, but also suppresses the large screen products in other industries, making it difficult to survive. It can be said that it has no difference in the limelight. This year is a critical moment for the leap of small spacing from quantitative change to qualitative change. The market potential is huge. Therefore, it is inevitable that some fish eyes confuse pearls. What problems should users who prefer small spacing full-color LED display screen pay attention to when purchasing large display screen, so as to maximize their own investment utilization on the premise of meeting the application needs?

The first point: "low brightness and high gray" is the premise

In order to ensure the viewing comfort, the primary concern of users when purchasing small spacing LED products is the brightness. In the traditional LED display technology, reducing the screen brightness will cause the loss of gray, and the loss of Gray will directly affect the picture quality, that is, the color is not rich enough. Therefore, an important criterion of high quality and small spacing LED screen is to achieve the technical index of "low brightness and high gray".

In actual purchase, users can follow the principle of "the more brightness levels recognized by human eyes, the better". The so-called brightness level refers to the brightness level of the image that human eyes can distinguish from the darkest to the whitest. The more brightness levels recognized, the larger the color gamut space of the display screen, and the greater the potential to display rich colors, The brighter the color and the higher the saturation of the video.

The second key point: in the selection of point spacing, we should pay attention to the balance effect and technology

Compared with the traditional LED display screen, the prominent feature of small spacing LED is smaller dot spacing. In practical application, the smaller the point spacing is, the higher the pixel density is, the closer the distance suitable for viewing is. On the contrary, the farther the distance suitable for viewing is.

In order to achieve the best visual effect and have the best visual distance, users can make a simple calculation. There is an established formula, that is, the best visual distance = point spacing / 0.3 ~ 0.8. The smaller the point spacing is, the higher the cost of small spacing LED display screen is. Therefore, in the actual purchase, users should comprehensively consider their own cost, demand, application scope and other factors.

Third point: resolution: pay attention to match with the back-end signal transmission

However, the smaller the distance between the LED display screen and the actual display screen, the better the resolution of the LED display screen should be. At the same time, the smaller the distance between the LED display screen and the actual display screen should be considered.

For example, in the application of security monitoring, the front-end monitoring system generally includes video signals in D1, h264, 720p, 1080i, 1080p and other formats, but not all small spacing LED screens on the market can support video signals in the above formats. Therefore, in order to avoid the waste of resources, users must choose small spacing LED screens as needed, Avoid blindly following the trend.

At present, small spacing LED display is still in the stage of rise and development. In order to avoid blindly catching up with the trend and ignoring other factors in the actual purchase, users should pay attention to selecting large brands and enterprises with good reputation. A set of cost-effective small spacing led system is the joint action of many factors, and the three aspects emphasized in this paper are the key elements that users pay attention to in the application of purchase.
