As we all know, a good screen can improve the user experience of consumers. At present, it seems that there are only a handful of manufacturers that can produce OLED screens in the world, and only Samsung, LG, and BOE can produce. As the leader of domestic OLED screens, BOE has been chasing in this regard, and the gap with the world is getting smaller and smaller, and it has become the screen supplier of Huawei P series and mate series high-end mobile phones, which has been recognized by all parties. .
04ab0Recently Apple 12 will use BOE screens, but according to the latest supply chain news, BOE’s screens failed to pass Apple’s official quality inspection. Apple’s requirements for suppliers are very high, and Apple’s requirements are often higher than those of the industry. This is also an Apple mobile phone. One of the reasons why it has been loved by everyone. Only the Samsung screen passed Apple's quality inspection and was adopted on the iPhone X and 11 series.

BOE's screens have been adopted by Huawei's high-end devices, but why did Apple give up using BOE's OLED screens? In fact, Samsung is not completely in its own hands on OLED screens. The main OLED material Host in the table below is supplied by Dow Chemical (Red), Nippon Steel (Green), Samsung SDI (Green), SFC (Blue), etc. , Host is the luminescent material of the luminescent layer.
0d4a#04a0#0d4a#04a0# Out of the raw materials for OLED screens, Japan’s monopoly of OLED screen raw materials, it can be said that Japan controls the upstream market of screen raw materials, and Samsung has to bow to these companies.
0d4a#04a0#0d4a#04a0# For the screen, there is another evaporation machine. As the world's largest importer of screen panels, China used to be monopolized by Korean and Japanese companies. BOE successfully broke through the technology monopoly of Japanese and Korean companies on the evaporation machine and realized the evaporation machine. The localization of this product saves a lot of costs, but it should be understood that our domestic vapor deposition machine is only a low-end vapor deposition machine, while the high-end vapor deposition machine can only be produced by Canon Tokki, and tokki is purchased by Canon in 2007. Since then, Canon is the only one in the field of high-end evaporation machines. For some reasons, Canon (Canon) Tokki's evaporation machines are only sold to Samsung, and for JD.com, they are relatively backward models.

Eastern, from Apple a#4da#4da The screen also tells us that there is still a certain gap between the quality of our domestic screens and the screens of other countries in the world, but the BOE screens can be considered by Apple, which fully demonstrates BOE's technical strength in OLED screens over the years. But we need to recognize the facts. At present, in the field of screens, we are still chasers. We must not be blindly arrogant. Only by working hard can we become a winner and occupy a place in the field of OLED screens.
