Embodiment Construction

[0045]As mentioned in the background, in the flexible display device in the related art, when the flexible screen is rolled, the inorganic layer of the flexible screen is prone to breakage or the film layers in the flexible screen are separated from each other. The inventors have found through research that the reason for this technical problem is that when the flexible screen is rolled onto the reel, the curling radius of the flexible screen is too small, that is, the curling curvature of the flexible screen is too large, resulting in excessive bending stress of the flexible screen, thus The inorganic layer of the flexible screen is broken or the film layers in the flexible screen are separated from each other, thereby affecting the display effect of the flexible display device.

[0046] In view of the above technical problems, the flexible display device of the embodiment of the present application is provided with a support mechanism, the support mechanism includes a scroll ...

Abstract

The embodiment of the invention relates to a flexible display device and a mobile terminal, and belongs to the technical field of display. The embodiment of the invention aims to solve the problem that an inorganic layer of a flexible screen is easy to break or film layers in the flexible screen are separated from one another in the prior art. The flexible display device comprises a flexible screen and a supporting mechanism, the supporting mechanism comprises a reel and a plurality of arc-shaped supporting plates hinged in sequence, and one arc-shaped supporting plate at one end of the arc-shaped supporting plates hinged in sequence is hinged to the reel; one end of the flexible screen is fixedly connected with the reel; the plurality of arc-shaped supporting plates which are hinged in sequence are configured to form a spiral supporting piece surrounding the reel when the flexible screen is curled around the reel; when the flexible screen is unfolded, a wave-shaped supporting piece is formed, and all wave crests of the wave-shaped supporting piece are coplanar. According to the flexible display device provided by the embodiment of the invention, breakage of the inorganic layer of the flexible screen and / or mutual separation of film layers in the flexible screen can be avoided.

Description

technical field [0001] The embodiments of the present application belong to the field of display technologies, and in particular relate to a flexible display device and a mobile terminal. Background technique [0002] With the continuous development of display technology, people put forward higher requirements on flexible display devices, and require that the size of the display screen of the flexible display device can be adjusted. A flexible display device usually includes a reel and a flexible screen. One end of the flexible screen is connected to the reel. When the reel rotates, the flexible screen is rolled or unfolded so that the display image of the flexible screen can be adjusted. However, when the flexible screen is rolled, the inorganic layer of the flexible screen is likely to break or the film layers in the flexible screen are separated from each other, thereby affecting the display effect of the flexible display device. Contents of the invention [0003] In v...
