According to the global market situation, mainland China is the largest investment area of ​​AMOLED in the world. Although Samsung is still the largest in the OLED field, the myth of Samsung monopoly has begun to loosen as BOE began mass production of AMOLED. However, there are still four major problems in the mature application of AMOLED, and domestic OLED cornering overtaking still needs to work hard.
OLEDs have shown strong competitiveness as next-generation display technologies, especially their bendable and foldable characteristics, which have brought more innovation space for electronic form applications. Although the current small and medium OLED market is dominated by Samsung, in the layout of small and medium-sized OLEDs in mainland China, the 6-generation production lines that have been put into production or under construction include BOE Chengdu and Mianyang production lines, and Huihui Optoelectronics Shanghai and Nanjing production lines. The production lines of Kunshan Guoxian Gu'an Production Line, Shanghai Tianma and Huaxing Optoelectronics will gradually increase, and the domestic OLED industry is expected to achieve overtaking.
"From the perspective of global display industry development, China and South Korea have become the main driving areas for the global OLED industry, and mainland China has the most active investment in the OLED field." Shenzhen Guoxian Technology Co., Ltd. General Manager Omulan in 2017 China's flexible display technology (materials) International Forum media meeting said that there are data showing that since 2016, global OLED new line investment reached 315.5 billion yuan, of which China invested 256.6 billion yuan, becoming the world's largest AMOLED investment. Area.
The data shows that the current global OLED production and output value maintains a high-speed growth. It is expected that the output in 2018 will increase by 50% year-on-year, and the output value will increase by 60%. In 2017, the smartphone OLED screen will reach a scale of 25 billion US dollars, while Samsung accounts for 95% of the market, which means that it is basically Samsung's exclusive.
Of course, all other manufacturers, especially mainland Chinese manufacturers, have been lagging behind and have been catching up. In October this year, BOE’s sixth-generation flexible AMOLED production line in Chengdu has already achieved mass production, breaking foreign monopoly, and the new production lines of manufacturers such as Huaxing Optoelectronics, Tianma, Visionox, and Huiguangdian are also steadily advancing. It will further promote the application of OLED industrialization in China. At the same time, with the strong support of the government, China has shown a certain breakthrough in the upstream industrial chain of the industry. China's display industry is welcoming an unprecedented favorable situation.
At the same time, OLED has also become the focus of industry attention, especially the use of OLED screens for iPhone x smartphones will further promote the industrial application of OLED technology. With the development of more advanced manufacturing equipment and materials engineering technology, the application of bendable, foldable and curved display in electronic products is further enhanced. In the future, OLED display technology will be widely used in smart phones, VR, wearable devices, televisions, Tablet PCs and smart cars have broad market prospects.
There are still four problems in the mature application of AMOLEDBased on the industrialization of OLED and the broad market prospects, is the AMOLED application mature? According to O'Mullan, it turns out that making flexible devices in the true sense is harder than you think. At present, AMOLED is still in the early stage of industrialization development, and there are many problems to be solved, mainly reflected in the following aspects: First, the technical process of AMOLED backplane is not mature; Second, AMOLED display pixel realizes the choice of technical route; Third, the choice of AMOLED film-forming process route; Fourth, the above three aspects, AMOLED cost is still very high.
Ou Mulan stressed that due to equipment manufacturing efficiency or unit capacity, yield, material utilization and other aspects, AMOLED has theoretically simple structural advantages, but the current cost of AMOLED is still high, it is difficult to compete with TFT-LCD. .
However, AMOLED and TFT-LCD will be a parallel industry trend in the next few years. Xu Shiying, secretary general of the Organizing Committee of China Flexible Display Technology (Materials) International Forum, said that AMOLED will gradually infiltrate, and AMOLED and TFT-LCD have different application advantages in different application fields. The development of OLED cannot completely replace TFT- LCD, the two have different strengths in different fields. Therefore, the application ratio of AMOLED flexible display in small and medium size will gradually increase, but TFT-LCD will continue to be adopted.
As one of the domestic display module companies, Guoxian Technology is also keeping up with the latest technology development and increasing the development and layout of flexible display technology. Ou Mulan said that Guoxian Technology has achieved development results in comprehensive screen, narrow frame, high color saturation, high resolution, high brightness and eye protection technology. In the future, Guoxian Technology will strengthen upstream and downstream enterprises in the industrial chain. Deep cooperation, promote the application development of domestic flexible display technology, and provide the market with more experiential flexible display products.
Overall, the OLED field is still dominated by Samsung, and it has the most advantages in mass production technology, but there is still room for improvement in the supply of upstream materials, equipment, and technology. On the basis of the original display technology, especially in the field of display research and development in the past 10 years, coupled with the huge application market, the mainland has certain advantages in the flexible OLED mass production process, and the curve overtaking will not be without may.
Displacement sensor, also known as linear sensor, is a linear device belonging to metal induction. The function of the sensor is to convert various measured physical quantities into electricity. In the production process, the measurement of displacement is generally divided into measuring the physical size and mechanical displacement. According to the different forms of the measured variable, the displacement sensor can be divided into two types: analog and digital. The analog type can be divided into two types: physical property type and structural type. Commonly used displacement sensors are mostly analog structures, including potentiometer-type displacement sensors, inductive displacement sensors, self-aligning machines, capacitive displacement sensors, eddy current displacement sensors, Hall-type displacement sensors, etc. An important advantage of the digital displacement sensor is that it is convenient to send the signal directly into the computer system. This kind of sensor is developing rapidly, and its application is increasingly widespread.
