It is reported that Apple first submitted patent related to folding screen in 2013, and then submitted several new versions.
Earlier, when Xiaomi mix alpha was released, Lei Jun said that the concept mobile phone mainly explored a series of technologies such as surround screen, 108mp and titanium alloy material.
Obviously, Apple's patent is more difficult to mass produce than millet mix alpha. Apple has always been less aggressive about new technology, so it's unlikely to see "surround screen" in a short time.
But at least apple is considering surround screens, and it may soon become the mainstream of mobile phone full screen exploration.
