The development of flexible smartphones has basically gone through these three stages:
Flexible OLED Screens: Self-emissive, enabling excellent image quality, natural colors, and no harmful blue light; the screen is flexible and can be bent and folded; flexible, thin, lightweight, heat-free, and comfortable to hold, meeting the needs of mobile phone development.
Flexible Curved OLED Screens: The curved design of the sides of curved screens greatly increases the screen-to-body ratio and widens the viewing angle. Compared to flat screens, curved screens offer better visual effects, grip, and operability.
Flexible Foldable OLED Screens: Foldable phones represent a new form of smartphone development, giving phones tablet-like features; combining office, communication, and entertainment functions, offering a large-screen experience and enabling multiple uses in one device; easy to open and close, and portable.
