Digital signage is a brand new media concept, which refers to public places where large shopping malls, supermarkets, hotel lobbies, restaurants, cinemas and others converge, and publish business, finance and entertainment through large-screen terminal display devices. Information multimedia professional audio-visual system. Its purpose is to broadcast advertising information to a specific group of people in a specific physical place and a specific time period, so that it has the effect of advertising. In foreign countries, some people put it alongside paper media, radio, television, and the Internet, calling it the “fifth media.” Overview With the continuous development of modern technology, the application of digital display technology will be everywhere. Digital signage relies on the integration of network and multimedia technologies to release and process information in the form of media, and interact with customer feedback in a timely manner. It has been widely used in finance, telecommunications, hospitals, stores, supermarkets, hotels, public places and other fields. The system adopts advanced design concepts and open interfaces, which can integrate a variety of applications. The digital signage system can count and record the playing time, number of times and playing range of multimedia content. It can also realize more powerful interactive functions while playing, which brings opportunities for the creation of new media. Features 1. Foolish program editing interface. Operators can use editing and publishing software to publish various text, icons, animations, videos, audio information and other digital information anytime, anywhere without special training, and integrate them into a “digital sign” for

In the past two years, the continuous shrinking of LCD splicing screens and the rapid rise of small-pitch LED displays have challenged the market application status of DLP seamless splicing screens. It has become an indisputable fact that application market share has been eroded. Suddenly, the decline of DLP seamless splicing screens became widespread. So, has the DLP seamless splicing screen really reached the “place where heroes are useless”? The answer is of course no. In the high-end large-screen display market that focuses on image quality, DLP seamless splicing screens are still the mainstream. Take the power industry as an example. Driven by the tide of social informatization, the construction of power informatization continues to accelerate-with the help of informatization means, the unified management of specialized functions such as grid dispatching, operation mode, relay protection, and communication can be realized. This means that in actual operation, the power dispatch center needs to monitor and monitor all the data, environmental parameters, and images of each substation, understand the situation of each station in real time, and be able to respond to emergencies in a timely manner. With a huge and complex power supply line, if you want to ensure the accuracy of monitoring information, a fine screen display will naturally become a guarantee. DLP seamless splicing screen not only has the unique advantage of “zero” stitching, it guarantees the exquisiteness of the display screen, but also can display static images for a long time to meet the continuous monitoring needs of

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.
