On September 9, Reuters quoted the Korean media Chosun Biz as saying that Samsung Display and LG Display, two major Korean OLED screen manufacturers, will stop supplying high-end smart phone screen panels to Huawei from September 15 due to the sanctions and prohibitions of the United States.

At present, Samsung refused to comment on this news, while LG said that their shipments of screen panels to Huawei were limited, and the U.S. sanctions and prohibitions had little impact on the company, and would continue to focus on the diversification of customer groups.

Huawei has previously maintained close contact with Samsung and LG in screen procurement. This year, the P40 series used the OLED panels supplied by LG and Samsung respectively. Last year, the flagship Mate 30 series used Samsung's AMOLED screens. Earlier, the Mate 20 Pro had a "green screen door" incident because of LG OLED panels.

In addition to Korean enterprise panels, Huawei has also purchased a large number of domestic OLED panels such as BOE in recent two years and configured them on some flagship models. Huawei will have to rely more on domestic panels after Samsung and LG cut off supplies.

Of course, for Huawei, the biggest impact of the new round of sanctions and prohibitions that began on September 15 is the foundry and purchase of chips. TSMC will stop working for Hisense's Kirin chip after that day. The Kirin 9000 (rumored, not exactly named) carried by Mate 40 series may become the "swan song" of Kirin chip; The alternative plan to purchase chips from MediaTek will also be blocked after the US ban in August.
