Nanjing Happy screen, LED electronic screen in recent years, LED display applications, technology and applications development aspect, forming a diversified broad market, related industries constitute significant changes have taken place. 2012, the National LED display applications industry maintained a relatively stable overall development trend, the National LED display applications industry market reached 25.3 billion yuan, 22 billion yuan compared with the year 2011 increased by 15%. LED-based materials and related technology is developing rapidly, and promote the application of LED display increasing levels. In recent years, LED large screen display has been continuously improved and perfected in high-density, high-definition technology and machine reliability, technological level and so on. LED display control system and gradually formed the core of a standardized product for different applications in the semiconductor landscape lighting, urban lighting and other fields has also created a series of new LED display applications. Indoor high density, fine pitch LED display its entire screen without patchwork, no cell color, better color reproduction, higher dynamic refresh rate, longer life and other advantages, indoors tradition, high-end display product market began with the traditional rear-projection DLP, LCD and other competition. From P2.5 to P1.8 then P1.5, indoor high density fine pitch LED display has been widely used in broadcasting, road traffic control, public security monitoring, power systems, military, water conservancy, urban management industries. With increasing levels of application, the material needs of the entire industry, the device also has a new change. On-chip devices, the demand for surface mount devices on the rise, and require small discrete wavelengths, color consistency and strong; antistatic ability, high reliability; highly cost-effective, easy to cost control. In terms of the driving element of the refresh rate and intelligent control have higher requirements. In power systems, require energy saving, reliable, able to achieve redundancy. Overall, the application of LED display industry, the overall technical level of the basic pace with international, introduce innovative products in recent years, the industry's technological innovation active product development capabilities continue to strengthen. Adapt to the needs of specific applications of technology development, technical support and technology to ensure empowerment of key technical and relatively rapid development of mainstream products, lead and led the emerging markets, creative projects large LED display applications currently emerging, LED display application market Overall still in relatively intense competition. Traditional LED display application market areas are fully market-oriented, market competition has been more intense, while the rental market has appeared more intense beacon war between several major manufacturers to cut prices as the main means huge impact on the industry. To respond to changing market demands and increasingly fierce competition in the market, LED display applications in marketing business model has also been actively innovation and try to form a sales-based export-oriented foreign trade marketing, sales mainly to the terminal project The terminal marketing, agents and distributors nationwide to establish channels of marketing, development and production division of labor OEMODM marketing, focusing on specific markets professional marketing and marketing a variety of BT or BOT model.
