LCD brightness Brightness represents the amount of brightness of a picture per unit area. Specifically, the density of the amount of light passing through the normal direction of the screen. The unit is [CD / m2] or nit（1 nit = CD / m2).Brightness depends on the amount of light passing through the LCD and color film, and the brightness of the backlight.   LCD backlight requirements: The liquid crystal should have good transmittance; light weight; It should be thin and not easy to damage; The area light source with uniform brightness is the best; Low cost; The light color is pleasing to the eye, the primary color is rich, and the brightness can be adjusted; Low power consumption and easy power supply

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. Display, what we have a deeper understanding of digital signage at this stage should be the touch screen. This is a typical display device and an important link between digital signage and users. 3. The operating system and the shell have no soul, and the display itself has no soul.

It is a common misconception that all electronics should exhibit the same colors, especially with devices with the same make and model. However, this is often not the case. Have you considered what’s actually causing the picture to look different? It is a common misconception that all electronics should exhibit the same colors, especially with devices with the same make and model. However, this is often not the case. This is illustrated with a simple experiment: when you put the same image on two monitors side-by-side, you have at least a 95% of chance that the images will not look the same, and you will probably find yourself in a situation like that shown in Figure 1. 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. Most people go to a large electronics store and decide between the TVs on display. Then, you pick the one with the colors or image quality (or price) that you find
