Alas, many friends have been asking recently, where is the right LED curved screen? Just like novices who are always confused about the "golden composition point" when learning photography, people who work in engineering are often worried about this. Today we will talk about it by breaking it apart, and you will know what you think after you keep it.

​​Learn first: Why do curved screens have to be special?​​
Some people may ask, where is the installation of ordinary large screens not? Why are there so many things to pay attention to in curved screens? Here is a key point:​Ray itself is the design language​. Like a shopping mall revolving door, its meaning is to guide the flow of people. The curved angle of the arc screen directly determines the visual impact force. Experimental data shows that a curved screen with a radius of 3 meters can attract 47% of the more eye-catching sight than a flat screen.

So what should I consider specifically? Let’s list three hard indicators:

• ​​Space depth​​: The audience's recent viewing distance should be at least 2 times the screen height
• ​​Ambient illumination​​: Do not exceed 1200lux indoors, and automatic light-shading system outdoors must be equipped with
• ​Structural load bearing​: The weight per square meter is most secure to control it within 35kg

​​Analysis of practical scenarios​
Don’t remember the theory, let’s look at the real cases directly. Last year, the main stage of an international music festival used a 270° circular screen with a radius of 8 meters. Why choose this size? The organizer said that it is necessary to ensure that the audience in the back row can also see the singer's close-ups clearly, while allowing the audience on both sides not to feel the picture deformed.

Let me give you another down-to-earth example, the curved advertising screens commonly found in shopping mall atriums. What is emphasized here is "looking down but not looking up" - the installation height must be between 2.8-3.5 meters, which is exactly the range of natural view of the abortion. Too low to meet your head, too high to tired your neck.

​​Three major issues that must be clarified before installation​​

1. ​​"Can this wall eat and live?"​​
   Although the curved screen has a cool shape, its requirements for architectural structure are much higher than that of ordinary screens. For installation solutions with a span of more than 6 meters, steel structure reinforcement must be done. There is a real lesson: a certain exhibition hall did not perform load-bearing tests to install it directly, and the lifting parts were deformed after three months, and the maintenance fee was even more expensive than the screen.

2. ​​"Where is the power cord hidden?"​​
   This matter is related to the overall aesthetics. The professional approach is to embed the wire trough on the back of the arc, so as not to take the open line in order to save trouble. The smartest design I have ever seen is to make the thread grooves into decorative stripes, which are both practical and beautiful.

3. ​​"How to operate daily maintenance?"​​
   Make sure to leave enough maintenance space during installation! It is recommended to reserve 80cm channels on the top of the screen and leave an invisible access door on the side. Don’t wait for a problem to build a scaffolding, the cost will rise sharply.

​​The cold knowledge that experts know​
Maybe you will be curious why some curved screens look very comfortable? The secret is​Radius of curvature and pixel arrangementcooperation. For example, if a screen with a radius of 5 meters is used, if a P3-pitch lamp bead is used, the optimal viewing distance is 1.5 times the radius - that is, about 7.5 meters. This data was repeatedly tested by the laboratory, so it is correct to do it accordingly.

There is another point that is easy to ignore:​Ambient light compensation​. The screen with an intelligent dimming system can automatically adjust the brightness. The actual data show that this screen can increase the screen clarity by more than 60% in a mixed light environment in the mall. However, be careful not to install the light sensor probe directly opposite the screen, as it will be disturbed by its own light.

After all, choosing an installation location is like falling in love - it depends on the "eye" and more importantly, it is scientific. Newbie remember these three iron laws:​First measure the load bearing and then draw the picture. Reserve space for maintenance. Intelligent systems must not be missing.​. If you encounter a situation where you are not sure, just look for a manufacturer with 24-hour technical support. The engineer will walk around the site, which will be more effective than you think about it yourself for half a month.
