Digital signage is a dynamic information dissemination system based on digital audio and video technology, which has a natural connection with the flat panel display industry and IT industry. Therefore, the competitive entry of display manufacturers and IT manufacturers can be called "having the advantage of proximity". From the perspective of the inherent advantages of industry development, both display manufacturers and IT manufacturers have played a significant role in promoting the development of the digital signage industry. The continuous networking of digital signage makes its relationship with the Internet increasingly close, while professional IT manufacturers have been working hard in the field of the Internet for many years, having prominent advantages in the security and stability of systems. In the current complex network environment, plus the fact that digital signage generally needs to run for a long time without supervision, the demand for the stability and security of the system keeps increasing, and the participation of IT manufacturers will further promote the overall development of the industry to meet market demands. For example, the digital signage platform technology jointly launched by Intel and Microsoft last year, based on Intel Core processors and the latest version of Microsoft Windows Embedded operating system, can help solution providers quickly establish a stable digital signage network. As the social informatization continues to advance, digital signage applications have penetrated into multiple fields of society. Large shopping malls, hotel lobbies, supermarkets, cinemas, office buildings and other public places where people gather have all become their display platforms. The continuous heating up of the application market leads to continuously increasing investment in the industry, and the extremely attractive market growth space makes more and more IT and flat panel display industry giants start to enter this field driven by interests. In the actual application of digital signage, the display effect of its front-end display is the most direct experience for users, directly determining the user's purchasing intention. Compared with the digital signage industry, the large screen display industry is relatively more complete in terms of technology and industrial chain. Currently, most display manufacturers entering the digital signage industry are well-known brands in the industry. Their mature display technology and rich experience will make the display effect of digital signage products achieve leapfrog development, thereby enhancing user interest and accelerating market promotion. Relevant surveys show that major global flat panel display manufacturers, including LG, Mitsubishi, NEC, Panasonic, Pioneer, Samsung, Sharp, and Sony, are gradually expanding their market share in global digital signage. The fields and scope involved in the digital signage industry are becoming increasingly extensive, helping governments establish a clean and efficient image and strengthen public supervision; helping enterprises improve management levels, worker skill levels, and enterprise safety production levels; helping educational institutions better use multimedia teaching and online teaching resources, maximizing quality educational resources. Nowadays, "wherever there is information display, there should be digital signage" and "wherever there are traditional bulletin boards, there is the market for digital signage", more and more users are using digital signage to enhance their competitiveness and create more value. To a large extent, the mature technology of display manufacturers and IT manufacturers has become a catalyst for the rapid maturity of digital signage hardware technology. Industry insiders believe that in the era of refined applications, the mature technology of flat panel display manufacturers and IT manufacturers will become a solid backend for high-definition, intelligent, and large-screen display application demands, promoting further enhancement of market application scale.
