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 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.

The principle and characteristics of DLP seamless splicing screen

Almost all current smart projections use DLP seamless splicing screen projection technology, so how much do you know about this technology? Today I will briefly analyze the working principle and characteristics of this technology. The light source hits the light on the lens to obtain usable parallel light. The parallel light passes through the color wheel to obtain a uniform rectangular spot, which is then processed by DMD, the core component of DLP seamless splicing screen projection technology. Finally, the light is hit on the projection lens and passed The lens gets the projection we need, which is the working principle of DLP seamless splicing screen projection technology. DLP seamless splicing screen display board has extremely fast response time, you can switch independent pixels many times when displaying a frame of image. In addition, the strong reflective surface of the DMD chip can eliminate the obstacles in the light path and allow more light to be projected on the screen, and maximize the use of the projector’s light source to obtain a higher contrast picture. These are DLP seamless splicing screen projections. Advantages of technology. In addition, in terms of size, the DLP seamless splicing screen chip is lighter and smaller, which is one of the reasons why DLP seamless splicing screen projection technology is widely selected for small-size products such as smart projection. In addition, at the end of last year, Texas Instruments also launched a smaller size 1080P chip for smart projection. The compression of the chip size
