Isn't the curved screen a patent of Samsung? Even if other manufacturers break through the technical bottleneck and use hyperbolic screens as mobile phones, shouldn't they pay Samsung patent fees?

At present, the domestic mobile phone has the screen used by VIVO's latest Xplay 5, which is also provided by Samsung.

Therefore, in order to produce hyperboloid AMOLED screens, enterprises need to negotiate with Samsung and pay a certain fee. If a mobile phone manufacturer wants to use it, it needs to negotiate with Samsung Electronics, which will sell it to the mobile phone manufacturer.
