"High Low light gray" is the premise of the problem is the brightness <br> <br> To ensure viewing comfort, users in the purchase of small spacing LED products primary concern. In the traditional LED display technology, reducing the brightness of the screen will cause loss of gray scale, and the loss of gray scale will directly affect the picture quality, that is, the color is not rich enough. Therefore, an important criterion for the high-quality small-pitch LED screen is to achieve the "low-light high-ash" technical indicators.
In the actual purchase, the user can follow the principle that “the more the brightness level can be recognized by the human eye, the better.†The so-called brightness level refers to the brightness level of the image that can be distinguished by the human eye from the darkest to the whitest, which is recognized. The higher the brightness level, the larger the color gamut space of the display, and the greater the potential for displaying rich colors. The more vivid the color of the video is played, the higher the saturation.
Pitch selection, pay attention to balancing effect and Technology <br> <br> compared with the traditional LED display, LED small spacing prominent feature is a smaller dot pitch. In practical applications, the smaller the dot pitch is, the higher the pixel density is, and the closer the distance is suitable for viewing. Otherwise, the farther the distance is suitable for viewing.
For a small-pitch LED display to achieve the best visual effect, with the best viewing distance, the user can make a simple calculation, there is a set formula, that is, the best visual distance = point spacing / 0.3 ~ 0.8. The smaller the dot pitch, the higher the cost of the small-pitch LED display. Therefore, in actual purchase, the user should consider its own cost, demand, application range and other factors.
Resolution: to be noted that the rear end of the signal transmitting <br> <br> with LED display for a small pitch, the smaller the 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, while paying attention to the screen's own resolution, but also consider its combination with the back-end signal transmission products.
For example, in the security monitoring application, the front-end monitoring system generally includes video signals in the formats of D1, H264, 720P, 1080I, 1080P, etc., but not all small-pitch LED screens on the market can support the above several formats. Video signal, so in order to avoid waste of resources, users must choose on-demand when purchasing small-pitch LED screens, and should not blindly catch up with the trend.
At present, the small-pitch LED display is still in the stage of development. In the actual purchase, users should not blindly catch up with the trend and ignore other factors, especially to choose the big brands and good reputation companies to buy. A set of cost-effective small-pitch LED systems is the synergy of many factors, and the three aspects highlighted in this article are the key elements that users use in their purchases.
What is an wall ap? In life, many times we will encounter a bad network situation, generally when the network is bad will affect everyone's mood, everyone likes the situation of network unobstructed, so will go to find a way to keep the network smooth, and wall ap can help you keep the network unobstructed, let's take a look.
1. wall ap
What is the wall ap is a lot of people want to know the problem, wall ap can let everyone's network has been smooth, wall ap is the most important part of the networking, wall ap and the socket at home, you can transmit signals through the wall ap, but want to really use the wall ap you need to install some network cables in each room in advance.
In other words, the wall ap can be directly called a Wireless Router, the wall ap can be used as the antenna of the router, if you put the wall ap in the room, then the signal in the room will be strengthened, but now people prefer the wireless router, so the wall ap also needs POE and AC two devices to assist.
2. AC
AC machine is the most common kind of router, it is very different from ordinary router, can not be used by simple insertion, but need to be set up several times to connect to the network, but also need to be combined with the wall ap to be better used, so the wall ap is very important. The combination of router and wall ap can enhance the network signal.
3. ap networking scheme
The ap networking scheme not only requires the wall ap, but also needs to add the control system, you can choose commercial, you can also choose home, for the network signal requirements of relatively high enterprises can choose commercial, before choosing the networking mode need to be carefully considered.
