Speaking of folding screen smart phones, ZTE launched the first folding smart phone ZTE AXON M in the overseas market last month. However, AXON M does not use a folding flexible screen, but is equipped with a screen of the same specification on both front and back sides of the phone. Two screens can be combined into one by rotating the shaft, It is not a so-called "folding screen".

In contrast, Apple has applied for a patent for a smartphone with a foldable flexible screen in the United States. According to the patent documents, the electronic device of the patent is equipped with a foldable flexible screen, which can be folded and unfolded directly by bending. According to the patent description, this is a real folding flexible screen, rather than a "folding screen" composed of two screens.

According to previous reports, Apple's folding flexible screen may be provided by LG, and LG has expanded its OLED production line in South Korea. Nevertheless, Samsung's flexible folding screen will make faster progress. Samsung has shown flexible AMOLED screens in exhibitions for many times. It is reported that Samsung's flexible folding screen smartphone will be officially launched in 2020.
