Samsung Display were BOE are fighting a legal battle for quite some time, mostly in the US. The most important one was based on Samsung's claims that BOE, and also some phone parts retailers, infringe upon its AMOLED patents, and have asked the US International Trade Commission (ITC) to ban the import of any devices that use BOE's AMOLED displays, in addition to after-market AMOLED displays.
In July 2025, the ITC found BOE guilty as charged, and following its preliminary ruling to ban BOE's AMOLED, it updated that it will likely ban the import of BOE's AMOLEDs to the US for 15 years, and issued a Limited Exclusion Order (LEO). The ban was not to include devices that use BOE's AMOLEDs, though (such as Apple's iPhones), but it was still to be a problem for BOE which is why the company likely agreed to pay the royalties to Samsung.
