Digital signage is a dynamic information dissemination system based on digital audio and video technology, and it has natural connections with the flat panel display industry and the IT industry. Therefore, the competitive entry of display manufacturers and IT manufacturers can be called "having the advantage of proximity." From the perspective of inherent advantages in industry development, both display manufacturers and IT manufacturers have played a significant role in promoting the development of the digital signage industry. The increasing networking of digital signage has made its relationship with the Internet increasingly close, while professional IT manufacturers, with years of experience in the Internet field, have prominent advantages in terms of system security and stability. Given the complex current network environment and the fact that digital signage generally needs to operate for long periods without supervision, the demand for system stability and security continues to rise. The entry of IT manufacturers will further drive the overall development of the industry to meet market demands. For instance, Intel and Microsoft's jointly launched digital signage platform technology last year, based on Intel Core processors and the latest version of Microsoft Windows Embedded operating system, can help solution providers more quickly establish stable digital signage networks. The flat panel industry finds itself in a deep loss abyss as manufacturers divide into two major factions. With the continuous advancement of social informatization, digital signage applications have penetrated multiple areas 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 has led to increased industry investment, and the highly attractive market growth space has driven more and more IT and flat panel display industry giants to enter this field due to interest-driven motives. In the actual application of digital signage, the display effect of its front-end display is the most direct user experience, directly determining the user's purchasing intention. Compared to the digital signage industry, the large-screen display industry is relatively more complete in terms of technology and the industrial chain. Currently, most display manufacturers entering the digital signage industry are well-known brands within the industry. Their mature display technology and rich experience will enable the display effect of digital signage products to 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 global market share in digital signage. The scope and range of the digital signage industry involve an increasingly wide array of fields, helping governments project an image of integrity and efficiency, strengthen public oversight; helping enterprises improve management levels, worker skills, and enterprise safety production levels; assisting educational institutions in better utilizing multimedia teaching and online teaching resources to maximize quality educational resources. Nowadays, "wherever there is information to be displayed, there should be digital signage" and "wherever there are traditional bulletin boards, there is a market for digital signage." An increasing number of users utilize digital signage to enhance their own 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 maturation of digital signage hardware technology. Industry insiders analyze 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 expansion of market application scale.
