Recently, the reporter learned from the Municipal Economic and Information Commission and BOE that the situation of foreign companies in the global mobile phone screen has been broken by the Beijing high-tech enterprise BOE. Last month, BOE’s first domestic and global second flexible screen production line was mass-produced. Beijing enterprises that have begun to lead the development of the global flexible display industry have already achieved “healing†from “follow-up†and gradually launched an impact on “leadingâ€.
Display show "Jitsu"
E-newspapers can be stacked at random and imported into the bag. The mobile phone is not afraid of falling and not afraid of folding. It can even be bent like a bracelet and worn on the arm. This cool technology life is becoming a reality.
Recently, BOE's first flexible display production line in China in Chengdu announced that it will achieve mass production in advance. This means that China has broken the exclusive supply of South Korea's Samsung and become the second country in the world to mass produce flexible displays.
"啪", once the mobile phone has been free-falling in the past, you have to change screens in nine or nine, or you have to change your phone. And if you use a flexible screen, the phone screen will not be so fragile. Compared with the traditional display, the flexible AMOLED display as the next-generation display technology replaces the traditional glass with plastic, and has the impact resistance that the mobile phone screen does not currently have. The intuitive benefit of a more flexible and less damaging plastic is that the chance of a broken screen is plummeting.
In addition to being easy to deform and bend, and with many advantages such as high resolution, fast response, low power consumption, etc., the flexible display can be applied not only to mobile phones, but also to clothing, jewelry, and automobile instrumentation and center consoles. Etc., huge market potential makes it more competitive in the market. At present, major international companies including Samsung, Sharp, LG, Philips and so on have attached great importance to this new technology.
New products break the monopoly of Korean companies
However, in the past, such high-tech display products were the only ones in South Korea. Due to limited production capacity and huge demand, some insiders revealed that “domestic mobile phone manufacturers sometimes can't buy related products even with moneyâ€, and the degree of tightness can be imagined, which also greatly restricts the market competitiveness of domestic manufacturers.
In May of this year, BOE successfully lit the first flexible display. From display technology to mass production, the industry usually takes a year or two to leapfrog. BOE only took half a year. It is reported that BOE's flexible screen production line is expected to produce nearly 600,000 substrates per year, and demonstrates the strong technical strength of Chinese companies to the world at "Beijing-East Speed".
At the delivery ceremony of BOE's first batch of flexible screen products held recently, Jingdong delivered this flexible display to more than ten leading domestic mobile phone manufacturers including Huawei, OPPO, vivo, Xiaomi, ZTE and Nubia. The industry predicts that this will also enable the comprehensive competitiveness of domestic mobile phones in high-performance mobile phones to increase simultaneously. Soon, we can use a mobile phone that can be rolled up, a TV that can become a picture axis, a foldable computer, or even a product that is completely beyond people's imagination.
Billions of R & D every year to "grind out" the sword of innovation
Why can a hard and fragile display become soft? "This is mainly because OLED technology realizes self-illumination, so the display no longer needs hard backlights, color filters and other components." Vice President, Flexibility of BOE Technology Group The head of the technical team, Wang Dazhao, showed the reporter the new self-illuminating display material, the white powder placed in the bottle and can. “These luminescent materials emit different colors of red, yellow and blue according to different arrangement. Compared with glass, the use of plastic material finally makes the screen light and soft.â€
At BOE's R&D headquarters in Beijing, R&D personnel revealed that there are countless difficulties in the development of flexible screens. For example, since the plastic substrate used in the flexible screen is different from the conventional glass substrate, it is necessary to ensure that the plastic substrate does not deform during high-temperature evaporation, and the process requirements are extremely high; the OLED display material is extremely sensitive to oxygen and moisture, and once the package is not tight The display device may fail; the display screen can be folded, and the circuit can withstand bending, ensuring that the display effect is not affected by the loss after repeated bending... Under the joint research of hundreds of flexible display developers, BOE has completed breakthroughs in the important processes of flexible display technology such as flexible substrate fabrication, OLED light-emitting layer preparation, film packaging and stripping.
Continuous innovation investment is the driving force for realizing technological and industrial breakthroughs. In 2009, it was nearly 500 million yuan, 1.1 billion yuan in 2011, 3.32 billion yuan in 2015, and 4.14 billion yuan in 2016. These rapid growth figures are the annual investment in research and development of BOE. The huge R&D investment also brought a rich return. In the first half of this year, BOE added 4,000 new patent applications, and the cumulative number of patents available has exceeded 55,000.
