Development and Prospects of Digital Signage

Digital signage is a relatively advanced identification product. In recent years, we have seen more and more digital signage in reality, and the application scenarios are gradually expanding in depth. If you follow a relatively stereotyped expression, that’s it. “Digital Signage” is a brand-new media concept. It refers to public places where large shopping malls, supermarkets, hotel lobbies, restaurants, cinemas and others converge. Multimedia professional audio-visual system for financial and entertainment information.” In fact, the digital signage we currently see does stay at the basic display stage, but we can’t simply interpret the digital signage as an advertising machine, because the advertising machine is one-way The information conveying itself does not recognize the user’s behavior or instructions, and we now focus more on the intelligentization of digital signage, which is the essence of the development of digital signage. Compared with traditional display signs, one of the biggest features of digital signage is that it can interact with users. This interaction may be in a variety of ways, such as traditional mechanical buttons, touch screens, mobile phone scan codes to send related instructions, and even voice. There are also body movements, etc., which can all be used as interactive methods. In fact, we can deeply experience this in the field of science and education, especially in the robot-related interaction process, we can interact with the big screen through body movements. This is theoretically a typical development direction of digital signage. . In the initial stage, the digital signage we understand is

What are the pixels of LCD?

Pixel is a kind of unit. Generally speaking, it is invisible to the naked eye. How can we see the pixels of LCD? That is, if the image of LCD is magnified several times, many small square dots will be found. These small square dots are actually the so-called pixels.   The LCD splicing unit of LCD is a full-color screen, and red, green and blue are the primary colors of colors. Because LCD has many colors to realize, it needs to combine the red, green and blue lights to form pixels.   The pixel of LCD is a unit used to calculate the digital impression. Just like the photo taken, the digital impression also has continuous tone. If you enlarge the impression several times, you will find that these continuous colors are actually composed of many small dots near the color.   In addition, the pixels of LCD include real pixel display and virtual pixel display. The two technologies are different. The virtual display adopts virtual pixel technology, that is, LCD multiplexing technology. The same LCD light-emitting tube can be combined 4 times with adjacent LCD light-emitting tubes (down, down, left, and right combinations). Generally speaking, the pixel is a unit. The pixels of the current LCD display are 1920 * 1080, and the pixels of the Department display can be as high as 3840 * 2160. The higher the pixel, and more clearer the picture will be.

What are the basic components of LCD?

We will use some electronic devices in our life, LCD module is one of the electronic components. Everyone’s understanding of it must be relatively strange, and then we will talk about the knowledge in this respect.   The following is an introduction to the three basic components and features of LCD. Let’s take a look with the editor: Liquid Crystal Materials Liquid crystal material is the main body of liquid crystal display. Different devices use different liquid crystal materials. Most liquid crystal materials are composed of several or even more than ten kinds of single liquid crystal materials.   Polarizer The light sheet, also known as polarized light, is made of plastic film material, coated with a layer of optical pressure sensitive adhesive, which can be pasted on the surface of the liquid crystal cell. There is a protective film on the surface of the front polarizer, which should be removed when using. The polarizer is afraid of high temperature and high humidity, which will depolarize or blister under high temperature or high humidity conditions.   Glass Substrate A kind of float production thin glass sheet with extremely flat surface, the surface of which is evaporated with a layer of zn203 or sn02 transparent conductive layer, i.e. ITO film, is processed into transparent conductive pattern. If scratched, cut or corroded, the vacuum device will be scrapped.
