Now extremely folding or the probability of not round and smooth bending state, the cabling stress for reducing bent area concentrate the probability of impaired fracture, into
And reduce the probability that display Problem of Failure occur in flexible display panels.
It is core of the invention thought above, following will be combined with the drawings in the embodiments of the present invention, to the embodiment of the present invention
In technical solution be clearly and completely described.Based on the embodiments of the present invention, those of ordinary skill in the art are not having
Under the premise of making creative work, every other embodiment obtained be shall fall within the protection scope of the present invention.
Fig. 1 is the schematic diagram of the section structure when a kind of flexible display panels provided in an embodiment of the present invention are bent,
Fig. 2 is the schematic diagram of the section structure when a kind of flexible display panels provided in an embodiment of the present invention are not bent, and Fig. 3 is
The overlooking structure diagram of a kind of hold mode group provided in an embodiment of the present invention.In conjunction with Fig. 1 to Fig. 3, flexible display panels include
The display screen body 2 and branch hold mode group 1 being stacked, display screen body 2 include bent area BB, the branch hold mode of corresponding bent area BB setting

Display screen body 2 forms multiple second segmental structures 21, and the second segmental structure 21 is arranged along the overbending direction XX ' of bent area BB.It needs
It is noted that Fig. 1 to Fig. 3 exemplarily only shows position of the bent area BB of display screen body 2 relative to display screen body 2,
The embodiment of the present invention is not construed as limiting bent area BB relative to the position of display screen body 2.
Flexible display panels generally comprise flexible substrate, and the material for constituting flexible substrate may include PI (polyimides),
Flexible display panels further include the pixel-driving circuit and luminescence unit in flexible substrate, and luminescence unit is in pixel driver electricity
The brightness of itself is adjusted under the control on road, flexible display panels show different pictures.Pixel-driving circuit is correspondingly arranged sometimes
The cablings such as clock signal wire, scan signal line, data signal line and power signal line.Flexible display panels, can be in bending
The corresponding region of flexible display panels is bent since one end of bent area, be difficult to avoid that during bending meeting
There is dead folding there are the bending shape of bent area or not round and smooth bending state, the i.e. bending shape of bent area include that angle is smaller
Bending interior angle, this allows for cabling of bent area since stress concentrates the probability of impaired broken string larger, increases Flexible Displays
There is the probability of display Problem of Failure in panel.
In conjunction with Fig. 1 to Fig. 3, the branch hold mode group 1 that corresponding bent area BB setting is arranged in the embodiment of the present invention includes multiple first
Segmental structure 11, when display screen body 2 is bent to the side of neighbouring branch hold mode group 1,2 shape of display screen body of corresponding bent area BB setting
At multiple second segmental structures 21, the second segmental structure 21 is arranged along the overbending direction XX ' of bent area BB, from bent area BB's
One end starts during bending to display screen body 2, so that the bending shape of the display screen body 2 of corresponding bent area BB setting
