A supporting structure of a foldable display device and the foldable display device

Abstract

The invention discloses a supporting structure of a foldable display device and the foldable display device, the supporting structure of the foldable display device is used for supporting a flexible screen of the foldable display device, and the flexible screen comprises at least two plane areas and a bending area for connecting the two adjacent plane areas; the supporting structure comprises supporting plates in one-to-one correspondence with the plane areas and a sliding piece arranged between any two adjacent supporting plates, the supporting plates on the two sides of the sliding piece area first supporting plate and a second supporting plate respectively, the first supporting plate is rotationally connected with the sliding piece, and the second supporting plate is slidably connectedwith the sliding piece. The first supporting plate and the second supporting plate can be folded in the direction away from the flexible screen, when the supporting structure is unfolded, the secondsupporting plate moves in the direction away from the first supporting plate, and the sliding piece is opposite to the bending area. According to the supporting structure of the foldable display device, the stress of the bending area of the flexible screen can be reduced, the flatness of the bending area is improved, and the display effect of the foldable display device is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a support structure of a foldable display device and the foldable display device. Background technique [0002] The foldable flexible screen mobile phone is an important trend in the development of modern mobile phones. The flexible screen of the foldable device usually includes a plane area and a bending area. The above bending area connects two adjacent plane areas, corresponding to the structure of the foldable flexible screen. The support structure of the foldable flexible screen mobile phone includes a planar support part and a bending support part, the planar support part is opposite to the planar area, and the bending support part is opposite to the bending area. [0003] In the prior art, a foldable device includes a planar support part and a bent support part, and the bent support part is connected between two adjacent planar support parts to drive the two adjacent plan...

AI Technical Summary

Problems solved by technology

Among them, the bending support part includes a foldable hinge assembly, the structure is relatively complex, and the stability of the unfolding and folding process of the structure is poor

In addition, the bending support part and the flexible screen have a certain thickness. When the bending support part drives the flexible screen bending area to unfold and fold, the bending support part corresponds to the length of the flexible screen in the unfolded state, which is less than the flexible screen in the bent state. The length of the screen causes the flexible screen to be subjected to tension in the bent state, resulting in a decrease in the service life of the flexible screen, and in the unfolded state, there are likely to be wrinkles in the bending area, and the display effect is poor.
