Led display monitor's history and related fields of application

Led displays the development has undergone three phases:

In 1990, before the formation of the development of led display screen.

On the one hand, the material limitations of LED diodes, led display applications not widely expand, on the other hand, display control technology is essentially communication control, objectively affected the display effect. This period of led screen in the broader foreign application, very few products in China to double-color: red, green, control mode for communication control, grayscale to single point 4 jidiao ash, the cost of the product is relatively high.

1990-1995, this stage is the rapid development of led display screen.

Entered the 1990s, the global it industry growth, information technology continues to break through in various areas, led display in LED materials and control technologies are emerging new results. Blue LED the successful development of chip, full color led screen to enter the market; electronic computer and technological developments in the field of microelectronics, in the display control technology has video control technology, display grayscale achieve 16-level grayscale, and 64-level gray-gray, the display of dynamic display effect increases dramatically. This stage, the led display in my development speed very quickly, from the initial few enterprises, the annual output of a few tens of development to the dozens of companies, annual production value of hundreds of applications, products involving financial instruments, sports, airports, railways, stations, road traffic, commercial advertising and telecommunications in telecommunications and many other fields, particularly in 1993 securities stock industry more led led display market growth. Led display in flat panel display areas product situation basically formed, led display industry become the emerging high-tech industry.

Since 1995, led display monitor's development into an overall improved steadily industry pattern adjustment and improvement.

At the same time, the led display industry internal competition, many small and medium-sized enterprises, product prices sharply, wider fields of application, product quality, standardization, and so a series of new questions concerned departments on the led display development attention and proper specifications and guides, the current work in this area is gradually deepening. China's led display industry after several years of development, formed a group has a certain scale of backbone enterprises. According to incomplete statistics, to the end of 1998, the total annual sales of over $ 50 million in 1000 has more than 20 enterprises, whose sales amounted to $ 6 billion, representing industry market more than 85% of the total. Engaged in led display of all enterprises have more than 100 employees in nearly 6000 people, industry annual sales of nearly $ 800 million RMB, 1996, 1997 's growth rate is maintained at around 40%, a slight drop in 1998. In the domestic market, the domestic market share of led display screen is almost 100%, the overseas similar product basic no market, 43 48th meeting Tianjin Sports Center, Beijing-Kowloon Railway, Beijing West railway station, airport, Pudong International Airport, both by domestic bid on behalf of the enterprise. Technical standards relative to lead.

Led display for applications involving social economy in many areas, including:

Ø securities trading, financial information display.

This field of led display was a few years ago the domestic demand led display of more than 50% remains as the main demand for led display industry. Shanghai Stock Exchange, thousands of Shenzhen Stock Exchange and the national securities, financial business organization widely used a led display.

Ø airport flights information display.

Civil airport construction requirements of the information display is clear, led display is the flight information display systems FIDS (Flight information Display system) preferred products, capital airport and Shanghai Pudong International Airport, in meilan airport, Zhuhai Airport, Xiamen gaoqi international airport, Shenzhen Huangtian Airport, Guangzhou Baiyun International Airport and dozens of new and expanded airport will use the led display products made in China.

Ø port, Station Visitors Guide information display.

With led display for the subject of information systems and radio systems, train arrival and departure reveal systems, ticketing information systems comprise transport hub of automation systems, Beijing, Beijing West railway station, Nam Cheong Station, Dalian and other domestic important railway station and port are installed the domestic manufacturers provide products and systems.

Ø Stadium information display.

Led displays have replaced the traditional light bulbs and CRT screen, the arena of the forty-third world table tennis championships to Tianjin Sports Center for the first time with domestic color video led screen, widely praised, Shanghai sports, Dalian Stadium and many other domestic important stadiums have adopted led display as the principal means of information display.

Ø road traffic information is displayed.

Intelligent transportation systems (ITS), in urban traffic, highways and other areas, led display as variable information board, the speed limit signs, etc., instead of similar foreign products, universally adopted.

Ø dispatching Center information display.

Power scheduling, vehicle tracking, vehicle scheduling, management, etc., also in the gradual introduction of a high density of LED display screen.

Ø postal, telecommunications, shopping malls, and other service areas of publicity and information display.

Nationwide service area are homemade led screen in the information display.

Ø advertising media of new products.

In addition to a single large indoor and outdoor display as advertising media, domestic cities appeared cluster led display advertising system; train led display advertising system also has dozens of columns to be used for passenger trains and is being promoted.
