Samsung Display is the biggest and most popular smartphone OLED panel manufacturer in the world. The company supplies OLED screens for hundreds of smartphone models, including the ones from Apple, Huawei, OnePlus, OPPO, Realme, Vivo, and Xiaomi. Huawei's recently released P40 series uses Samsung's OLED panels as well.
According to a report from South Korean tech publication TheElec, Huawei exclusively uses Samsung's OLED screen in the P40 Pro+. The P40 Pro uses screens from China's BOE as well as Korea's LG Display and Samsung Display. The Huawei P40 exclusively uses BOE's OLED screens. This goes on to show that Huawei prefers OLED panels from Samsung for its most premium phones, and this could be due to Samsung's higher quality and better supply chain.
