Recently, the reporter learned from the Municipal Commission of Information and the BOE that foreign enterprises have dominated the global market with flexible mobile phone screens and were recently broken up by Beijing high-tech enterprise BOE Last month, the first domestic BOE and the second flexible screen production line in the world Mass production.Starting to lead the global development of the flexible display industry in Beijing enterprises, has been 'run with' run and run ', and gradually to' lead 'to launch the impact.
Display show 'Jiu-Jitsu'
E-newspaper can be casually folded into the pocket, the phone is not afraid of falling from fear of folding, and even bent like a bracelet worn on the arm, so cool technology life is becoming a reality.
Recently, BOE's first flexible display line in Chengdu announced the mass production in advance, which means that China will break the exclusive supply of Samsung in Korea and become the second country in the world to mass produce flexible displays.
In the past, once the cellphone was free-fall, you had to change screens in the first place, or you had to change the cell-phones, and if you used a flexible screen, the screen would not be so fragile. Traditional display, flexible AMOLED display as the next generation of display technology to replace the traditional glass of plastic, with the current mobile phone screen does not have the impact of the more flexible and not easy to damage the intuitive benefits of plastics, is the mobile screen The odds of falling straight.
In addition to being able to flex and bend easily, with high resolution, fast response and low power consumption, the flexible display can be applied not only to mobile phones but also to clothing, jewelry, car dashboards and center console And so on, the huge market potential to make it more competitive market now, including Samsung, Sharp, LG, Philips and other international manufacturers attach great importance to this new technology.
New products to break the monopoly of South Korea
However, in the past this high-tech display products in the world are all Samsung South Korea alone due to limited capacity, huge demand, industry sources, 'domestic mobile phone manufacturers sometimes even holding the money to buy To related products', tightness can be imagined, but also greatly restricted the market competitiveness of domestic manufacturers.
This year in May, BOE successfully lit the first piece of flexible display.From the display technology to mass production, the industry usually takes a year or two across the board, BOE only half a year.It is reported, BOE's flexible screen production line is expected Nearly 600,000 substrates can be produced each year, demonstrating the strong technical strength of Chinese enterprises to the world with BOE Speed.
At the delivery ceremony of the first batch of flexible screen products BOE recently held, BOE delivered the flexible display screen to more than a dozen of the leading domestic mobile handset manufacturers such as Huawei, OPPO, vivo, Xiaomi, ZTE and Nubian, etc. The industry forecast, This also makes the overall competitiveness of domestic mobile phones in the future high-performance mobile phones to be synchronized upgrade may soon be able to use the phone can be rolled up, can become a draw-axis television, folding computer, or even beyond the imagination of people The product.
Billion each year research and development 'mill' innovative sword
Why is it hard and fragile display to become soft? 'This is mainly OLED technology to achieve self-luminous, so the screen no longer need a hard backlight, color filters and other components.' BOE Technology Group Vice President, Flexible Wang Daowei, head of the technical team, showed the reporter a new self-luminous display material - white powder placed in bottles and jars. "These luminescent materials emit red, yellow and blue in different combinations The use of plastic material has finally made the screen lighter and softer than glass.
For example, because the plastic substrates used in flexible screens are different from the traditional glass substrates, it is necessary to ensure that the plastic substrates are not deformed during the high-temperature vapor deposition. R & D personnel at BOE R & D headquarters in Beijing said that, , The requirements of the process is extremely high; OLED display materials are extremely sensitive to oxygen and water, once the package is not strict, the display device may fail; display screen can be folded, the circuit can withstand bending, to ensure that after repeated bending Not affecting the display effect due to the loss ...... Under the joint research and development of hundreds of flexible display developers, BOE has made breakthroughs in the important processes of flexible display technology, such as flexible substrate manufacturing, OLED light-emitting layer preparation, film packaging and stripping.
Continuous innovation investment is the source driving force for technology and industry breakthroughs: nearly 500 million yuan in 2009, 1.1 billion yuan in 2011, 3.32 billion yuan in 2015 and 4.14 billion yuan in 2016 ...... These figures, booming in recent years, Annual investment in research and development. Huge R & D investment has also brought a huge return, the first half of this year, BOE added 4,000 new patent applications, the cumulative number of patents available has more than 55,000.
