AMOLED screen was born in 2011. It took only seven years to develop into the mainstream screen panel. Because of its high contrast, power saving and bending characteristics, it is likely to replace LCD in the future. Smart phones such as Samsung, oppo, vivo, Huawei, moto and Xiaomi have all been introduced into AMOLED screen, which greatly increases the market demand for AMOLED panel. However, AMOLED panel supply chain is very short.
AMOLED screen was born in 2011. It took only seven years to develop into the mainstream screen panel. Because of its high contrast, power saving and bending characteristics, it is likely to replace LCD in the future.
smart phones such as Samsung, oppo, vivo, Huawei, moto and Xiaomi have all been introduced into AMOLED screen.
this has greatly increased the market demand for AMOLED panel, but the supply chain of AMOLED panel is very short.

What's the future of domestic AMOLED screen

the market demand for AMOLED panel is increasingAccording to the statistics of China's OLED industry market forecast and investment prospect analysis report, there are 15 OLED production lines under construction and planning in the world, including 9 in China.
in addition, some manufacturers in China are still planning to build lines.
experts call for rational investment in AMOLED, and improve the upstream and downstream layout of China's industrial chain, so as to avoid technology, talents, and other problems The risk of patent and other aspects.
the risk of patent and other aspectsIn the layout of OLED.
BOE will focus on small-size flexible AMOLED production line.
now OLED technology is rising.
it has become an irresistible technology trend in the field of small and medium-sized, which will become a new opportunity for Chinese enterprises.
in 2020, OLED shipment is expected to exceed 800 million pieces.
it is estimated that the annual compound growth rate of AMOLED shipment from 2015 to 2021 will be maintained at about 25%, It will become the mainstream of mobile phone market in the future.
.
domestic companies that have built AMOLED projects mainly include Tianma microelectronics, BOE, vicino, Huaxing optoelectronics, rainbow, Hongshi, Zhongxian technology.
Xinli, Nanjing No.1 organic optoelectronics and other companies.
many of these companies are just talking about it.
they have been addicted to talk, but they have not moved at all.
in recent years, many companies are still in the marketRainbow built a PMOLED production line in Foshan at the end of 2010.
up to now, we haven't heard of a large number of products being shipped. It's estimated that the yield rate is not good. It's said that we can only use other people's screens to bind our own chips to make modules.
soon after PMOLED was built.
rainbow announced that it would build AMOLED, but there was no news, As of this year, AMOLED project has been suspended.
Hongshi said that PMOLED can be mass produced.
however, like rainbow, it has not been heard that a large number of products have been shipped, and AMOLED has not been affected.
it is said that PMOLED can be mass producedBOE is said to have invested more than 10 billion yuan in Ordos to build AMOLED line.
in order to attract BOE, OrdosThe government gave them 1 billion tons of coal exploration rights. As a result, BOE built LTPS LCD line instead of AMOLED line in Ordos. Of course, according to BOE, it can be quickly rectified and switched to moled in the future.
but it can be seen from this one.
BOE didn't pay attention to AMOLED at all.
in fact, BOE did not pay attention to AMOLEDOther AMOLED production lines such as Huaxing optoelectronics have not been built, eitherIt's in the test line, or it's in the planned state.
to put it bluntly, it's all on the sidelines.
there's no formal cut in at all.
the project is in the planned stateNanjing No.1 organic optoelectronics Co., Ltd. is a special company.
it should also be basically completed at present and enter the stage of equipment installation and debugging.
but its main product is OLED lighting products.
and other companies are all OLED display products.
as a lighting OLED.
in essence, it should be PMOLED, not AMOLED.
the company has a long historyThe first leader of organic optoelectronics is Tian Yuansheng.
Dr. Wang Jinshan, both of whom come from Kodak.
Kodak is the first company in the world to get involved in OLED.
Deng Qingyun, the father of OLED, is from Kodak. Kodak has a large number of patented technologies in OLED, and PMOLED is the earliest sanmingzhi device structure, It's Kodak's patent.
the OLED lighting market has great potential.
I'm optimistic that Nanjing's first organic optoelectronics will enter as soon as possible.
I'm still optimistic about it. are on the top.Haihehui and Kunshan weixinnuo.
the rest are in the middle of bullshit.
all the others are in the middle of bullshitHopewell is an enterprise invested by Shanghai municipal government.
with an investment of about 4 billion yuan, it has been basically completed, and the equipment has been installed and debugged. According to its website, Hopewell has begun to supply AMOLED screens.
however, it is still a long way from real mass production.
it is estimated that it can be shipped on a small scale.
because AMOLED has a low yield rate, its life, resolution and so on, The luminous efficiency of materials needs to be improved. It is said that Samsung's yield rate was only about 10% when it was first built. As a newly built company, it is estimated that it will not be able to mass produce so soon, but it is much better than many other companies that are just talking.
He Hui's leader is Dr. Zhu Ketai.
he worked for DuPont solar before, He is an expert in thin film evaporation.
AMOLED technology has two main parts.
one is the production of LTPS TFT in the yellow light section, which is similar to TFT LCD, but in fact is relatively mature.
the other is thin film evaporation of organic materials.
AMOLED technology has two main partsThis is where Dr. Zhu Ketai's technical advantage lies.
in this respect, DrAt present, AMOLED project of weixinuo in Kunshan has been basically completed.
the new company is Guoxian optoelectronics, which is operated by Kunshan municipal governmentInvestment, equipment has basically been moved into the completion, and will soon enter the stage of production and commissioning. It is estimated that the.
PMOLED should be able to develop.
in small quantities next year. Its advantage is that it has been developing PMOLED industry. Its leading figure is academician Qiu Yong, vice president of Tsinghua University. Qiu is a born and educated student in Chinese mainland. The Chinese mainland Chinese mainland has the first PMOLED production line, and the supply of PMOLED is currently the world's first. The mainland can actually produce PMOLED with the largest volume of production. This is also the only AMOLED in the Chinese mainland. The AMOLED is the first.
built in China. Its large amount of experience.
accumulated in the OLED industry, especially organic light-emitting materials, thin film evaporation process. It has great advantages..
