In the field of transport, LED products are mainly used in expressways, urban transport, parking, subway, light rail display systems and traffic lights. After a few years ago, the competition pattern in the information board market gradually became clear and the market was relatively stable. Market structure and the main manufacturers traffic market LED products each year the total demand of about 3 to 5 billion, at present into the traffic guidance screen, traffic lights, variable intelligence panels and other products produced by enterprises are not many, but in these enterprises, Shanghai Sansi and Shenzhen Coship also occupied more than 80% of the two markets, with Banda, Qingsong, Liad, Tianjin Huawang and Nanjing Luopu dividing the rest of the market. Shanghai think twice now has about 900 production and sales display. Technology or market trends Demand for a variety of products in the next few years coexist, the new part of the graphical display with LED will become a new low-cost advantages of expression, and communications technology integrated wireless GSM / GPRS intelligence board will be in the city and part of the highway to be applied.
