What kind of products is the most competitive in the LED electronic display industry?At that time, it was a small-spacing full-color led electronic display screen, which not only ranked top in the industry, but also occupied little market share of other large-screen products.So let‘s analyze what factors users should pay attention to when purchasing led electronic displays, so as to maximize their investment utilization rate under the premise of meeting application requirements.
One, "low light high gray" is the premise
When we choose LED products with small spacing, the first thing we pay attention to is brightness, so as to ensure the comfort of viewing.In traditional LED display technology, reducing the brightness of the screen will lead to the loss of grayscale, and the loss of grayscale will directly affect the picture quality, that is, the color is not rich enough.Therefore, an important criterion for judging high-quality small-spacing LED screens is to achieve the technical index of "low light and high gray".
In actual in the choose and buy, the user can follow "the level of brightness of the human eye can identify the more is better" principle, the level of brightness of the so-called, is refers to the human eye can distinguish the brightness of the image from the black to the white level, the level of brightness of identified, the more that display color gamut space is larger, shows the greater the colorful natural potential, broadcast video color is more bright-coloured, the higher degree of saturation.
Two, point spacing selection, to pay attention to the balance effect and technology
Compared with traditional led electronic display screen, the prominent feature of small spacing led is smaller point spacing.In practical applications, the smaller the point spacing and the higher the pixel density are, the closer the distance suitable for viewing will be; otherwise, the farther the distance suitable for viewing will be.
In order to achieve the best visual effect, the user can simply calculate the optimal visual distance for the small-spacing LED address display screen. There is a given formula, that is, the optimal visual distance = point spacing /0.3~0.8.The smaller the point spacing, the higher the cost of small spacing LED electronic display screen, so in the actual purchase, users should consider their own cost, demand, application range and other factors.
Iii. Resolution: pay attention to match with the back-end signal transmission
For small-spacing led electronic display screen, the smaller the point spacing, the higher the resolution, and the higher the resolution of the picture. However, in practice, industry users want to build the best small-spacing led electronic display system. While paying attention to the resolution of the screen body, they should also consider the collocation with back-end signal transmission products.
In security monitoring applications, for example, the front-end monitoring system, generally includes the D1, H264, 720 p, 1080 I, 1080 p format video signal, but not all the small distance between the LED screen on the market can support the above several format video signal, so in order to avoid the waste of resources, the user when small spacing LED screen of choose and buy, be sure to on-demand choice, avoid blindly pursued trend.
