Statistics show that the output value of LED display industry in mainland China in 2012 was 24. 1 billion yuan, up year on year. Although the industry is developing, it has shown signs of weak growth. In the external environment, the country's strict thrift has a huge impact on the LED display industry: the reduction of large-scale performances has greatly weakened the LED display rental market, not only the number of corporate orders is small, but also many renters have withdrawn from the market; The slowdown in municipal engineering construction has also had a great impact on the performance of some engineering-based LED display companies. In the outdoor advertising market, the share of LED display has increased from 15. 5% in the first quarter of this year. 5 increased to 17. 8, but LED display companies benefit from it. This is because the increase in the LED display advertising market comes from the gradual recognition of the advertising value of the original points, rather than the increase in the advertising points of the LED display. On the contrary, high-quality installation locations are becoming more and more scarce, and negative factors such as light pollution make it difficult to approve large-screen outdoor installation, which makes it more difficult for advertising operators to open up the market. LED display companies will find it difficult to get new orders. On the other hand, with the popularization of SMD technology, more and more enterprise automation equipment are used and the production efficiency is getting higher and higher. Under the condition of limited market demand for LED display screens, many large-scale enterprises are facing the problem of how to digest production capacity. Enterprises are pushing LED advertising machines or entering new marketing new blue sea. The traditional market demand is sluggish, and it is necessary to digest excess production capacity. LED display screen enterprises begin to refine the display market and compete with traditional display devices. In terms of technology, with the improvement of LED chips and packaging technology, the distance between LED display lamp beads is getting smaller and smaller, and the definition is getting higher and higher. The progress of the industry has made the LED display screen break the restriction that it is only suitable for long-distance viewing, and it is getting closer and closer to the audience. LED Small spacing and advertising machine are representative products. At present, although the small LED spacing has attracted the attention of most industry insiders and the media, however, the promotion focus of Lianjian Optoelectronics, Dehao Ruituo and other industry companies at this stage is on LED advertising machines with lower unit prices and larger shipments. As the media equipment provider of Sinopec gas station, Dehao Ruituo has signed orders for more than 2000 P6 outdoor LED advertising machines. At present, more than 100 P6 outdoor advertising machines have been put into use. In addition, in the indoor high-precision display market, the cooperation between Ruituo and Wanda Hotel also brings a lot of imagination space for the LED advertising machine business. While Lianjian Optronics actively participates in various forums and activities of downstream advertisers and promotes its LED advertising machine named Electronic totem in professional channels. At present, it has received orders from major customers such as Phoenix City Media. it is applied in hotels, railway stations and other fields. It is understood that the current outdoor LED advertising machine quotation is generally about one to 20 thousand yuan per square meter, a 122 inch LED advertising machine does not consider various configuration schemes, to 3. Calculated by the price of 575 m², the final price is about 80 thousand yuan, and if it is an indoor LED display screen, the price only needs more than yuan. So but from the aspects of price consider LED advertising machine than hundreds of 100,000 on the millions of LED large screen have more of market space. In terms of media value, compared with large LED screens, LED advertising machines are easier to form LED advertising network in the regional scope, and the cost is also low, which is easy to be welcomed by regional advertising companies. LED advertising machine will replace LCD to become the mainstream equipment of outdoor media. In the field of advertising display equipment, LCD display screen and LED display screen have always been a river of water: LCD advertising machine is close to the audience, and the media radiation range is within 100 m². the LED large screen has a wide range of spread and can cover thousands of square meters of audience. However, with the improvement of Display accuracy, LED display screen has broken the restriction that it is only suitable for long-distance viewing. Many LED display screen manufacturers have begun to introduce LED advertising machines to compete with LED advertising machines. In the industry, different companies have different names for LED advertising Machines. Ruituo display and Lianjian optoelectronics are called LED advertising screen brushing machines, Liad is named LED Poster TV, and LED poster machines. In terms of size, the size of LED advertising machine is generally larger than that of LCD screen brushing machine. The size of LED screen brushing machine named Electronic Totem jointly built by Optoelectronics reaches 122, and the small MiniLED poster machine of Qingsong technology also has. the LCD advertising machine is generally 46-inch, 55-inch, 70-inch three specifications, can be 82-inch. It is understood that the cost of LCD screen brushing machine increases geometrically with the increase of size. More than 100 inch is even more expensive. For advertising operators, the cost-effectiveness is far less than that of LED advertising machines of the same size. As a means of production, customers attach great importance to the cost-benefit ratio of the equipment. Due to the large size of the screen, LED advertising machines are not easy to be blocked, can carry more advertising information, and have shocking visual effects. the content is easier to reach the audience, so that the price of advertisers is large. Therefore, from the perspective of comprehensive income, the price of LED advertising machine is far less than the cost of LCD, and it can receive more than twice the benefit of traditional LCD advertising machine.
