The groove being arranged on plate runs through the schematic diagram of multilayer inorganic layer；Fig. 7 is the part of flexibility touch-control display panel at the position hatching line P1
Schematic cross-sectional view.Fig. 8 is the stereoscopic schematic diagram that touching signals line enters groove cabling at the position hatching line P1.
As shown in figure 4, flexibility touch-control display panel provided in an embodiment of the present invention, is divided into fold domain from folding angles
A201 and includes non-collapsible region A202 is divided into display area A203 and frame region A204 from angles of display.It should be noted that
Division mode in figure is only schematical, and frame region can surround display area, and fold domain can be one can also
Be it is multiple, can be located between two includes non-collapsible regions or in the side of an includes non-collapsible region, fold domain is soft
The region that property touch-control display panel can bend or fold.Groove 205 is set on the inorganic layer of flexible array substrate, and
Groove 205 is located at the frame region A204 of display panel.
Specifically, when groove 205 is arranged on the inorganic layer of flexible array substrate, groove is where perpendicular to display panel
Run through inorganic layer in plane, as shown in Figures 5 to 7, flexible array substrate includes flexible plate 2081 and is set to flexible plate
On inorganic layer, inorganic layer is followed successively by passivation layer 2082, interlayer dielectric layer 2083, gate insulating layer 2084 and buffer layer 2085,
The groove being arranged on flexible substrates can run through one or more layers inorganic layer.Run through passivation layer 2082 as Fig. 5 shows groove,
Groove as shown in Figure 6 runs through passivation layer 2082 and interlayer dielectric layer 2083 simultaneously.Multilayer inorganic layer is provided on flexible base board, it is recessed
Slot can be set through one or more layers inorganic layer according to actual design demand, perforative inorganic by groove when display panel is bent
The crackle that layer generates can be blocked in groove, prevent the touching signals line in groove from breaking.In this embodiment, groove is hanging down
Directly run through institute's inorganic layer in the plane in display panel, keeps groove location exposure flexible plate as shown in Figure 7.Because flexible
Bottom plate is organic material, and the on the one hand discord inorganic layer contact of touching signals line, the stress that inorganic layer generates will not be to touching signals
Line impacts, and another aspect organic material is flexible, and touch control electrode is set up directly on organic material, can be protected, and increases
Strong flexibility, touching signals line generates broken string when preventing flexible display panels from folding.

(being not shown in Fig. 4, please refer to Fig. 7), wherein third line segment C3 is in non-collapsible district interior cabling.Non- folding is in flexible display panels
The touching signals line cabling being connected with touch control electrode in folded area is directly entered groove in non-collapsible district, but is in fold domain
The cabling needs for the touching signals line being connected with touch control electrode enter back into groove around non-collapsible district.In display panel bending,
The groove stepped locations of fold domain can generate stress concentration, if touching signals line fold domain through groove step enter it is recessed
Slot, stress when display panel is bent at groove step can cause touching signals line to break, and includes non-collapsible region, and groove step is not
Can generate stress concentration, therefore by fold domain draw touching signals line setting includes non-collapsible region through groove step enter it is recessed
Slot avoids fold domain groove step stress and touching signals line is caused to break problem.Fig. 7 is at 4 position vertical center line P1 of corresponding diagram
Schematic cross-sectional view, the position vertical center line P1 Fig. 4 is in non-collapsible district, and the upper surface of flexible plate 2081 is bottom portion of groove, Fig. 7
In show the first line segment C1 of part second line segment C2 outside the part of bottom portion of groove the first line segment C1, groove and connection
Third line segment C3 between second line segment C2.If Fig. 8 is the solid that touching signals line enters groove cabling at the position hatching line P1
Schematic diagram shows the part second line segment C2 outside the part of bottom portion of groove the first line segment C1, groove, third line in figure
Second line segment C2 outside section C3 connecting groove, then enters groove through groove step and is connected with the first line segment C1.Groove is hanging down
Directly running through institute's inorganic layer in the plane in display panel, simple production process is easy to make, when display device bending,
The crackle generated in institute's inorganic layer can be blocked in the position of groove leads to its fracture without expanding to touching signals line.
