As China's LED display technology continues to improve and its scale continues to expand, the market demand for global LED electronic displays will continue to grow rapidly in the next few years, with an average annual growth rate of over 20%. The global LED display market will reach 30 billion US dollars, and China will be the most important manufacturing base.
2016 LED display market development trend
Various applications of LED display are in the ascendant. Domestic LEDs have gradually formed hundreds of LED application products such as indication, signal and display, backlighting, etc., which are widely used in landscape decoration lighting, large screen display, traffic signal lights, digital display and indicator lights of home appliances, Automotive lights, mobile phones, digital cameras, computers, LCD TV backlights and other fields. With the development of technology, LED has also appeared in new application directions, such as aerospace, medical, agriculture and other fields. The market share of various types of LED display applications has steadily increased and the emergence and development of emerging application fields have created a good market space for the development of the LED display industry.
The strong support of the policy has also greatly promoted the development of the industry. A number of industrial policies proposed by the State Council, the Ministry of Science and Technology, the National Development and Reform Commission, and local governments have played an important role in promoting the development of the entire LED display industry and the optimization and upgrading of industrial structure. Under the background of industrial policy support, the scale of the industry is expanding day by day, and the industry chain is becoming more and more complete. It has created favorable conditions for enterprises in the industry to improve their competitiveness and participate in international competition. It is expected that a number of independent intellectual property rights and core competitiveness will emerge in China. Backbone business.
At the same time, the reduction in costs has also contributed to the expansion of consumer groups. The growth of LED displays over the past three years has proven that LED displays have become a hot product in the industry. LED displays have changed from scratch, from expensive to universally affordable, and have replaced projections and changed the world. People expect high-resolution LED displays to develop more rapidly.
LED displays are not new, but why did it suddenly become so popular? The answer is cost-effective. In recent years, the price of LED displays has dropped dramatically, thus attracting a broader user base. At the same time, product performance has also increased rapidly. The dot pitch is getting smaller and smaller, and the resolution is getting higher and higher. The LED display is no longer a tool for broadcasting a single message in a store or stadium. It has a more diverse usage. This development is both indoors and outdoors, especially for outdoor displays that present special requirements and challenges for manufacturers and installers.
Supply and demand relationship of LED display
At present, the LED display industry is oversupply. When you need to buy a product, you may receive 10-15 similar products from 500 manufacturers. The only thing that can distinguish these products is the price. In the absence of sufficient knowledge and training, the buyer may buy back an unsatisfactory product. They may be more likely to lose trust in LED technology than a company. This is a big blow to the entire industry.
Another problem that cannot be ignored is the ability of LEDs to resist environmental intrusion. You don't know if it will be used in a 40 ° C high temperature or minus 20 ° C environment. The first thing to deal with is the LED and the module itself. Seal them up. The bonding between the LED packaging technology and the module is very important. If the module is of poor quality or the glue cannot withstand high temperatures, the product will not succeed. The packaging technology of the module has been greatly improved in the past five years. Most LEDs have IP65 or IP54 protection, and some manufacturers have added fire protection to the product, such as a metal frame to ensure that the product will not melt under extreme conditions. Of course, this will increase the cost. Outdoors may have to pay 30% more, but if you want to use it for a long time, you will pay a little more. But for smart buyers, these costs are worth it. Although outdoor LED products that look equally spaced are more expensive than indoor products, they are not comparable in nature.
The future direction of LED display--human screen interaction
Of course, the LED display, especially the small spacing that shows such an excellent effect, is obviously not enough if it only improves its display effect blindly. We need to continue to explore how to diversify the functions and applications of display screens, and maximize the value of human screen interaction, which is an extremely important direction for the future value of LED display. We should not position the LED display only to statically play the carrier of the advertisement. We should think more about how to achieve good interaction between the viewer and the display, maximize the effectiveness of the advertisement, and let the output of the advertisement. Maximization will also indirectly increase the value of LED displays and broaden the application areas of LED displays.
In recent years, VR/AR technology has swept the entire market. Even many authoritative organizations such as the well-known research and analysis company DigCapital expect that by 2020, the market size of the VR/AR industry will reach 30 billion and 120 billion US dollars respectively. Obviously, the VR/AR industry will be a market of hundreds of billions of dollars in the future. As the most basic and important hardware facilities, the display will also have an explosive period, and the LEDs with high-definition image quality and seamless stitching will have a small spacing. The display will undoubtedly greatly enhance the user experience of VR products, and seems to have advantages over OLED, LCD splicing, and DLP splicing.
In the face of this new blue ocean, combining VR/AR with small-pitch LED display depth, opening up its new application model and profitable new model in the commercial field is a time-honored opportunity for enterprises. Many LED screen companies are eager to try, among which listed companies Liard, Lianjian and Ai Biessen have had a lot of moves recently. Chau Ming Technology Cai San has said that the development of the large-screen industry, including small-pitch LEDs, needs the support of the billion-dollar market. Applying this theory to the present, we can assume that VR/AR already has such industrial conditions. Coupled with policy support, it is no wonder that the industry giants first shot.
It is understood that as early as the end of 2014, Lianjian Optoelectronics took the lead in technical cooperation with a well-known domestic virtual reality system product and application development company, and jointly researched the VR virtual display system solution based on LED small-pitch display technology, mainly relying on virtual Various new types of military schools, driving schools, medical schools, sports schools, etc. of real technology, so that many students receive various trainings in the virtual environment. In 2015, the two parties successfully created the first educational application case based on VR+LED small-pitch technology (Wuhan First Business School), which provided the first step for VR+ education to provide a new technology application direction.
However, from a technical perspective, LED VR/AR applications face some challenges. The first is the price. In the category of 60 inches or less, the price of small pitch LEDs does not have an advantage, which will form a certain obstacle. On the other hand, the rapid growth of emerging technologies such as OLEDs has also brought certain threats. However, when the small-pitch LED display crosses this technical threshold and grafts the “wings†of VR/AR, the small-pitch market will usher in another spring.
