Now small pitch LED has become a well-deserved hot, look at this year's infocomm show, small spacing LED will also be full of the venue, and in the actual purchase, the industry users should pay attention to what issues in order to meet the application requirements under the premise , To achieve their own investment utilization maximization?
"Low light high ash" is the premise
In order to ensure the comfort of viewing, users in the purchase of small spacing LED products, the primary concern is the brightness problem. In the traditional LED display technology, reducing the brightness of the screen will cause the loss of gray, and the loss of gray will directly affect the picture quality, therefore, high-quality small spacing of an important criterion is to achieve "low light" Technical indicators.
In the actual purchase, the user can follow the "human eye can identify the brightness level of the more the better" principle, the so-called brightness level, refers to the human eye can distinguish the image from the darkest to the most white brightness level, The greater the brightness level, it shows that the larger the color space of the display, showing the potential of the rich color of the greater the natural.
On the point spacing choice, pay attention to balance the effect and technology
Compared with the traditional LED display, small pitch LED is a prominent feature of the smaller point spacing. In practical applications, the smaller the point spacing, the higher the pixel density, the closer the distance to watch, and vice versa, the more furtured the distance.
Small distance LED display In order to achieve the best visual effects, the best line of sight, the user can make a simple calculation, there is a established formula, that is, the best visual distance = point spacing / 0.3 ~ 0.8. The smaller the spacing, the higher the cost of the small pitch LED display, so in the actual purchase, the user should consider their own costs, needs, application and other factors.
Resolution selection, pay attention to the back-end signal transmission match
For small-pitch LED display, the smaller the point spacing, the higher the resolution, the higher the clarity of the screen, but in practice, industry users want to build the best small-pitch LED display system, Its own resolution at the same time, but also consider its back-end signal transmission products with.
For example, in the security monitoring applications, the front-end monitoring system, generally includes D1, H264, 720P, 1080I, 1080P and other formats of video signals, but not all small LED screen on the market can support the above format Video signal, so in order to avoid the waste of resources, users choose a small pitch LED screen, we must choose on demand, should not blindly catch up with the trend.
At present, the small distance LED display is still in the rise of the development stage, in the actual purchase, the user should not blindly catch up with the trend and ignore the other factors. A set of cost-effective small-pitch LED system is a combination of many factors, and this article emphasizes the three aspects, is the user in the purchase of the application focus of the object.
