Yesterday, Jingdong invested 6. 0. 7 billion yuan to cooperate with domestic manufacturers to jointly develop OLED applications in AR/VR field. It can be seen that not only in the industry, but also in large companies, they all want to take a share. The whole industry chain of OLED can be divided into upstream, midstream and downstream. The upstream includes LCD and OLED panels, and various Iphone8 required for module processing and assembly will be released soon. In addition to Apple's new mobile phone, there is also a new OLED full screen. OLED display technology has the advantages of self-illumination, wide viewing angle, almost infinite contrast, low power consumption, extremely high reaction speed, etc. As a benchmark in the mobile phone industry, Apple will definitely follow the trend in scope once there is any innovation. In the field of LED lighting, the price war has become white-hot, and the oversupply is irreversible. As a result, many manufacturers have transformed into OLED battlefields. Yesterday, Jingdong invested 6. 0. 7 billion yuan to cooperate with domestic manufacturers to jointly develop OLED applications in AR/VR field. It can be seen that not only in the industry, but also in large companies, they all want to take a share. The whole industry chain of OLED can be divided into upstream, midstream and downstream. Upstream includes LCD and OLED panels, various raw materials and components required for module processing and assembly, and midstream includes LCD and OLED panel manufacturing and display module assembly. the downstream industry is mainly the application field of various display products. China's industrial foundation is weak, the industrial chain is imperfect, and the competitiveness of upstream products is not strong. In China, there are many enterprises that have entered and are about to enter the OLED field, but they are mainly concentrated in the downstream panel manufacturing link of the industrial chain, and the upstream equipment and raw materials are weak. Most Chinese OLED manufacturers are still in the primary stage, and large-scale production is far from being realized. The manufacturing equipment and raw materials needed by Chinese OLED enterprises depend more on imports from Japan and South Korea. South Korea's Samsung is currently an enterprise with large shipments in the OLED Industry. It is not only its strong research and development strength in the display field that supports its position. there is also a huge demand for downstream mobile phones, tablets, TVs and other products. In China's OLED industry, there are no enterprises with large scale, complete products and high synergy. The imperfect industrial chain directly leads to the small output value of China's OLED industry. According to the data of 'China OLED Industry Market Forecast and Investment Analysis Report' by prospective Industry Research Institute, China's OLED output value in 2016 was about 62. 3. 2 billion US dollars, compared with other countries, less than 10 billion or more than 100 billion, the gap is obvious. But at the same time, it also shows that OLED in China will have a very large space for development. The government is also carrying out relevant policy planning. It is believed that with the joint promotion of the government and enterprises, China's OLED industry will usher in rapid development, with an estimated production capacity of 11. 71 million square kilometers in 2017. Combined with the current production capacity of OLED under construction in China, it is estimated that the production capacity will approach 3000 square kilometers in 2020, and the prospect is worth looking forward to.
