Flexible screen support structure, flexible display screen module and mobile terminal

Abstract

The invention discloses a flexible screen support structure, a flexible display screen module and a mobile terminal. The flexible screen support structure comprises a first flexible board, a second flexible board, a side plate and multiple electromagnets; the first flexible board is used for being attached to a flexible display screen, the second flexible board is arranged opposite to the first flexible board, and a gap is formed between the first flexible board and the second flexible board and filled with an electrorheological fluid; the side plate is arranged on the peripheral sides of the first flexible board and the second flexible board in an enclosing mode and seals the gap; the electromagnets are fixed on the first flexible board and located in the gap, each electromagnet is provided with a support face attached to the first flexible board and a side face which has an acute included angle with the support face, the side faces of every two adjacent electromagnets are attached to each other, and therefore the first flexible board is driven to be coiled. The flexible screen support structure supports the flexible display screen when the flexible display screen is unfolded, when the flexible display screen is coiled, the flexible display screen can be tightly coiled and contract conveniently, and therefore the user experience is improved.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a flexible screen support structure, a flexible display module and a mobile terminal. Background technique [0002] With the development of flexible display technology, more and more flexible display screens are used in mobile terminals, and the flexible screen support structure is used to realize shrinkage or expansion of the flexible display screen. At present, most mobile terminals have two kinds of flexible screen support structures in a folding mode or a curling mode. When the mobile terminal adopts a flexible screen support structure in a folding manner, the flexible display screen can be supported by plates after unfolding, but it is not easy to reduce the size after folding; when the mobile terminal adopts a flexible screen support structure in a curling manner, the flexible display screen can Curl and shrink the volume, but there is no supporting structure after unfo...

AI Technical Summary

Problems solved by technology

When the mobile terminal adopts a flexible screen support structure in a folding manner, the flexible display screen can be supported by plates after unfolding, but it is not easy to reduce the size after folding; when the mobile terminal adopts a flexible screen support structure in a curling manner, the flexible display screen can Curl and shrink the volume, but there is no support structure after unfolding, so it is not easy to support the flexible display

Therefore, there is currently no flexible screen support structure that can facilitate the shrinkage of the flexible display screen and facilitate the support of the flexible display screen after deployment.
