Development of LED display

it is mainly used to display text and simple pictures.
as a public information display tool in public places such as stations, financial securities, banks, post offices, it is in the early commercial field.
the development of LED display can be divided into the following stagesSecond, in the middle and late 1990s, dual primary color video screens with 64 and 256 gray levels began to appear.
the application of video control technology, image processing technology, optical fiber communication technology and so on promoted LED display to a new level.
the large-scale integrated circuit chip for LED display control was also developed and applied by domestic enterprises at this timeIn 2000, red, green and blue LED tubes flooded into China. At the same time, domestic enterprises have carried out in-depth research and development work. Full color displays produced by red, green and blue LEDs have been widely used, and have entered public places such as stadiums, convention and exhibition centers and squares, bringing domestic large screens into the full-color eraWith the rapid development of LED raw material market.
surface mount devices were also introduced in 2001. They are mainly used in indoor full-color screens. With their bright colors, high brightness, low temperature, and freely adjustable point spacing, they are accepted by people with different price demands. In just over two years, they are widely used in LED industry,The sales volume of the products has exceeded 300 million yuan, and the application market of surface mount full-color LED displays has entered the new century.
in order to adapt to the "slimming" plan of the 2008 Olympic Games.
Riad has developed surface mount Dual primary color displays, which are widely used in training halls and competition timing and scoring systems.
in the aspect of full-color screens in Olympic venues.
in order to reduce investment, most of the full-color screens are detachable, It can be used as a live broadcasting tool during the Olympic Games, and it can be used for leasing after the games, and it can be used as an application tool in public places such as performance and national policy release, so as to recover the cost as soon as possible.
in this way, it can be used as a live broadcasting toolAs far as the market is concerned.
China's accession to the WTO, the success of Beijing's bid for the Olympic Games and the Shanghai World Expo have become new opportunities for the development of LED display industry.
the domestic LED display market has maintained a sustained growth.
at present, the domestic LED display market share is nearly 95%.
the International LED display market capacity is expected to grow at an annual rate of 30%.
in the domestic market, the domestic LED display market share is expected to increase by 30%At present.
the main manufacturers of LED display screen are concentrated in Japan, North America and other places, and the export share of China's LED manufacturers is negligible.
according to incomplete statistics.
at present, there are at least 180 manufacturers producing full-color screen in the world, of which about 40 are large-scale companies with complete products. .
