What pitch of LED poster screen is the best? The answer is a height of 2 meters and a spacing of 1.875 is the best. The editor will give you detailed answers.
Ⅰ. Why is 2 meters high optimal?
1. Because the average height of people is about 1.7m, and the average height of models is about 1.8m, a total of 20cm needs to be reserved above and below the screen for display. Therefore, the ideal height of the screen should be about 2 meters, so that the characters occupy 90% of the poster screen. Left and right, the height of the displayed picture is the same as that of a real person. The picture is displayed at a ratio of 1:1 to the person without any scaling, which makes people immersive, achieves the best display effect, and is closer to the user's usage scenario and user experience;

At the same time, cloud cluster broadcast control, unified backend management, and remote control can be realized.
2. The height of traditional roll-up banners and display racks is 2 meters. As a more intelligent display carrier, the poster screen (advertising screen) can seamlessly play the design files of traditional roll-up banners and display racks to achieve rapid replacement.
Ⅱ. Why is it best to use 1.8 spacing and 6 cabinets？
Because according to ergonomic research and daily usage habits, 16:9 2K screens are the most popular. Therefore, Corrente designed 6 finished poster screens that can be directly assembled into a 1920*1080 resolution. A single poster screen can resolve The ratio is 320*1080. Each poster screen is spliced with 6 boxes, that is: the pixels of a single box are 320*180. In order to meet the 16:9 golden ratio, the size of a single box is specially customized to 600*337.5, so the spacing It is 1.875 (i.e. 600/320 or 337.5/180), which is the most suitable.

If you use cabinets with a spacing higher than 2.0 for splicing, the resolution will be less than 2K, which affects the playback effect. If you use cabinets with a spacing lower than 1.8 for splicing, the resolution will exceed 2k. Users need to customize additional materials. At the same time, the main control card will also need to be increased. cost, ultimately leading to a significant increase in product costs.
Ⅲ. Why not use 640*480 or 640*320 cabinets?
Because according to scientists' research on the human body structure, it was found that the field of view of the two human eyes is a rectangle with a length-to-width ratio of 16:9, so industries such as televisions and monitors design products based on this golden ratio size, so 16:9 is called Shown for gold. At the same time, 16:9 is the international standard for high-definition TV, used in Australia, Japan, Canada and the United States, as well as European satellite TV and some non-HD wide-screen TVs; my country's standard for digital high-definition displays was adopted in 2004 It has already been introduced, and there is a clear standard: the screen aspect ratio is 16:9.

The ratio of the poster screen spliced by 640*480 boxes is ultimately 4:3, and the ratio of the poster screen spliced by 640*320 boxes is ultimately 2:1. The overall visual effect is not as good as the 16:9 golden field of view. The length-to-width ratio of the 600*337.5 cabinet is exactly 16:9, and six poster screens are used to splice it into a 16:9 screen.
