The birth of LED
LED was born in 1923. When lossen. o. w studied semiconductors, he found that the p-n junction doped with impurities would emit light after being electrified, and thus developed led.
Formation stage
From 1990 to 1995, this period was a period of rapid development of LED display industry. LED full-color display began to enter the market. The production scale has expanded from a few enterprises in the initial stage, with an annual output value of tens of millions of yuan, to dozens of enterprises, with an annual output value of hundreds of millions of yuan. The application fields of products have expanded to many fields, such as financial securities, sports, airports, railway stations, highway transportation, commercial advertising, post and telecommunications.
Popularization stage
From 1996 to 2000, the LED display industry entered a period of overall improvement and industrial structure adjustment and improvement. The industry competition intensifies, the product price decreases, and the application field is broader. A series of new problems have emerged in the quality, standards, and other aspects of the products, which promote the further implementation of industry norms and guidance. By 2000, the overall scale of the industry was close to 1.5 billion yuan.
Promotion stage
From 2001 to 2005, China’s LED display industry developed steadily, and the overall scale increased year by year. In 2005, the industry scale reached about 4 billion yuan.
Innovation stage
From 2006 to 2008, China’s LED display industry entered a new historical stage of development, and the industrial scale increased rapidly. In 2007, the overall growth rate of the industry reached 44%. The intensive development effect of the industry was obvious. The technology of the whole industry has made continuous progress, and the standardization and technical system of conventional products have begun to be established, with the ability to design and implement special LED display engineering. China has become a major manufacturer and application country of LED display products.
Development trend of LED display
Energy-saving
Energy conservation and environmental protection has always been a new proposition in future life; Led display screen itself is very energy-saving, its characteristics are: high light efficiency, long life, easy to control, maintenance-free; It is a new generation of solid cold light source, with soft, bright, colorful, low loss, low energy consumption, and is a green and environmental protection product.
Lightweight
In the past, the weight of the iron box itself was not low, plus the weight of the steel structure, the overall weight was very heavy. In this way, many floor buildings are difficult to bear such heavy attachments, and it is not easy to disassemble and transport, and the cost is greatly increased. Therefore, the lightweight box is a trend that all manufacturers have to update.
Patentization
The competition in the LED industry is fierce. Almost every enterprise is competing for the market, grabbing customers and expanding the scale. But few enterprises really focus on product research and development. In fact, in order to maintain technical competitiveness and reduce the risk of technology spillover, patents are the best way to protect.
Small spacing
Small spacing has always been one of the hot products. At present, the indoor small spacing has broken through a few points, and the outdoor small spacing has also broken through P2. With the development of technology, the spacing will become smaller and smaller.
Interactive
Human-screen interaction is the ultimate trend of intelligent development of LED display. Why? Because in terms of products, the intelligent LED display is to enhance the user’s sense of intimacy and operating experience. 8 minutes to understand the working principle of LED interactive tile screen.
In the 21st century, intelligent LED display shows a trend of differentiation and diversification in the field of product application. In the era of smart city construction and big data interconnection, the outdoor media market has also ushered in new changes. The research and development of intelligent LED display products need more design and development for user-level operators, so as to truly solve the general needs of users, realize the universal intelligence of the product market, and finally win the recognition of the market.
