LG is preparing to build new OLED screens for an upcoming 6.5-inch iPhone, according to The Korea Herald.

LG will reportedly provide the larger panels while Samsung will continue to ship its OLED screens for smaller "5.8- or 6-inch screens." The iPhone X is the first phone Apple used OLED panels on. They're brighter and more colorful than traditional LCD panels, and Samsung is currently the sole provider.
