With the development of information technology, the digital transformation of the exhibition hall has become a worldwide trend in the field of exhibition design. Digital pavilions such as "digital Forbidden City" and "digital Dunhuang" let us enjoy unprecedented shock. With the arrival of the film Avatar, 3D technology has really entered the public's life. Holographic technology is amazing in digital interpretation. The interpretation of holographic sand table and image presentation make the demonstration items "live" and "move".The digital exhibition hall integrates multimedia creativity, breaking the time and space constraints of the traditional exhibition hall. The display content presents a design mode of virtual and real combination, making the display more scientific and technological.The change of science and technology and the development of technology have triggered the transformation of the times. Digital display pays more attention to the audience, which greatly improves the subjective initiative of participants, that is, the ability to display information.Digital display industry takes digital image as the core and has always been considered to belong to CG (digital image) industry, but this is obviously not completely appropriate. Through the combination of three-dimensional digital image and touch screen, infrared sensor, projection and other hardware, digital display has completely gone beyond the scope of digital image. It emphasizes the functionality of display, experience and interaction. Compared with CG, it is closer to the display industry. It is a higher-level display industry generated by the combination of three-dimensional digital image technology and display applications. Compared with the traditional display mode of "product display board", digital display has incomparable advantages.The most important feature of digital display is to visualize information. Whether it is text information, an idea or even a feeling, it can be transformed into three-dimensional digital images.Vision is the fastest way for human beings to obtain information. An image contains countless information points, which can be obtained in an instant by looking at the picture. If expressed in words or language, it not only takes a lot of time, but also prone to omission and misunderstanding. Therefore, digital display is a high-speed channel to establish the communication between virtual information and the real world by using visual images. For example, the advantage of digital display has been widely used in the display of the real estate industry. Developers use virtual three-dimensional images to visually display the real estate, so that consumers can see and buy at ease.The multimedia digital exhibition hall represented by WIMI. Us, a domestic holographic giant, uses a variety of multimedia and digital technologies (holographic technology), combined with the latest film and television animation technology, attracts audiences with a variety of novel technologies, takes multimedia and digital technology as display technology, and combines unique digital creative publicity content, Attract visitors with various novel technologies and realize the exhibition form of human-computer interaction. These include digital sand table, interactive projection, digital cinema, 3D promotional films, etc., which make the overall atmosphere of the exhibition hall more scientific and technological and give the audience a shocking visual experience.The traditional exhibition hall is generally displayed in the form of "exhibition board product commentator", which has a long history. In a very limited space, exhibition boards and products occupy a lot of space, which affects the transmission of information in the exhibition hall, and the display form is single.Micro beauty holographic digital exhibition hall is also called multimedia digital exhibition hall. The holographic presentation technology of micro beauty holographic cloud can create a virtualized integrated space presentation for the theme exhibition hall and build a theme museum with clear theme and ultimate effect. Give consideration to interaction, presentation, art and education.Holographic cloud HCDP online display platform comprehensively transplants the authenticity interaction and social attributes of offline exhibitions to the online, so as to build a new ecology of online exhibitions. Combined with the platform IP operation capability of holographic cloud, IP will be themed for offline commercial holographic exhibition.The digital exhibition hall displayed by Weimei holography is different from other traditional exhibitions. Especially in intelligence, interactivity and informatization. The digital exhibition hall generally has a main control system to control the classification, aggregation, reorganization, switching, etc. of all projects. Most of the items in the digital exhibition hall are controlled by gesture, motion capture and other interactive means, so the digital exhibition hall focuses on the interaction with users. This improves the interest of the whole exhibition hall. Many projects are displayed by means of information interaction such as face recognition or photo generation, which not only improves the interaction, but also plays a role in collecting user information.The digital application of micro beauty holography has been extended to all walks of life in the digital exhibition hall. Its application fields include holographic shopping experience, holographic live broadcast, holographic press conference, various theme pavilions of holographic government, holographic online holographic Exhibition Application and holographic IP commercial exhibition. For example, the digital exhibition hall of Memorial Hall combines various multimedia interactive exhibition items and themes with high-tech acousto-optic display means to leave a more direct display impression on visitors; The digital exhibition hall of the science and Technology Museum will reproduce the past history, characters and articles, so that visitors can experience an interesting journey of science, technology and culture like going back in time. The digital exhibition hall of enterprise pavilion integrates the enterprise culture into digital multimedia exhibition items and digital content display, and creates an interactive enterprise pavilion digital exhibition hall with distinct enterprise personality, etc.Digital image content combined with various hardware can derive a variety of display forms. Digital sand table, the combination of digital image content and sand table model, not only allows the audience to see the three-dimensional model, but also comprehensively understand various information of the area through the image content. 360 degree circular screen display system, with the screen surrounding the audience and shocking three-dimensional image content, can create a profound immersive experience. The multimedia interactive system can realize friendly man-machine interaction and exchange and quickly obtain rich information through the simple operation of the touch screen. In addition, there are interactive ground screen, interactive desktop, holographic projection, virtual book flipping, augmented reality... All kinds of display methods full of sense of science and technology. With the continuous combination of three-dimensional image content and more hardware, the display form of digital display will have unlimited possibilities.In the traditional display mode, "exhibition board product commentator" is the main display mode. Exhibition boards and products occupy a lot of space, and the area of exhibition board basically determines the amount of information that can be displayed. In today's increasingly expensive geographical space, this display is definitely not "green". In the digital display mode, an LCD can display the information of countless display boards, and can also adopt the dynamic picture content and interactive mode, which not only saves a lot of space, but also makes the display more vivid.Digital display has greatly surpassed the traditional display mode in terms of content and effect, and has completely exceeded the scope of traditional display in the field of application. At present, it has been widely used in real estate display, digital city, historic site restoration, virtual tour, activity special effects, project preview, industrial simulation... The content of the display has broken through the limitations of time, space and form. In the future, its application field will only be limited by people's imagination.The advent of 5g era has greatly improved the efficiency of digital display. The main advantage of 5g network is that the data transmission rate is much higher than the previous cellular network, up to 10 Gbit / s, faster than the current wired internet and 100 times faster than the previous 4G LTE cellular network. Another advantage is lower network latency (faster response time), less than 1 ms, compared with 30-70 MS for 4G. Due to faster data transmission, 5g network will not only provide services for mobile phones, but also become a general home and office network provider. The previous cellular network provided low data rate Internet access suitable for mobile phones, but a mobile phone transmission tower can not economically provide sufficient bandwidth as a general Internet provider of home computers.5g high data transmission rate and low delay are considered to have new applications in the near future. One application is practical virtual reality and augmented reality. Another application is the fast machine to machine interaction in the Internet of things.
