Abstract

A flexible screen support structure includes: a plurality of electromagnets and a controller electrically coupled to the plurality of electromagnets. The plurality of electromagnets are configured to be secured to the same side of a flexible display screen, and each electromagnet has a support surface configured to be attached to the flexible display screen and a side surface at an acute angle to the support surface. When the flexible screen support structure is expanded, the controller controls side surfaces of two adjacent electromagnets to be mutually repelled; when the flexible screen support structure is bent, the controller controls side surfaces of two adjacent electromagnets to be mutually attracted. A flexible display screen module and a mobile terminal are also provided.
