Four core components of digital signage

Digital signage is a problem that we have discussed more recently, because digital signage is a relatively advanced identification product, and it is also a direction of the development of the sign industry. Therefore, it is reasonable for us to analyze the key points of digital signage. On the one hand, we can strengthen the promotion of digital signage. On the other hand, we can also help the promotion of digital signage. Today, our theme is an integral part of digital signage, that is to say, digital signage. What are the parts? We sorted out the following 4 parts: 1. The shell part, the shell is the part that we can see intuitively. The digital signage is not just a screen. The digital signage we see in reality will be in various shapes, looks very beautiful and generous, not alone The display, therefore, this shell has a very important decorative role. Although it does not help digital signage in terms of function, digital signage is also part of the entire identification system. Of course, the outline of the shape needs to be consistent with the overall style, so , This shell is essentially as important as other identification products. 2.

The operating system and the shell have no soul, and the display itself has no soul.

The monitors do not need to be the same make and same model, but for illustration purposes, we used four identical monitor images.                  Different colors on same kind of Devices                                                                                Figure 1: Different colors on the same type of device Another place to witness this phenomenon is when you are shopping for a new TV.
