Embodiment
The principle and feature of the application are described in further detail with reference to the accompanying drawings and examples.It is appreciated that
It is that specific embodiment described herein is used only for explaining related invention, rather than the restriction to the invention.Further need exist for
It is bright, for the ease of description, the part related to invention is illustrate only in accompanying drawing.
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the application can phase
Mutually combination.Describe the application in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
Fig. 1 is referred to, the structural representation of one embodiment of the flexible display panels provided it illustrates the application.
In the present embodiment, flexible display panels can include flexible parent metal 10, touch control electrode layer 11 and protective layer 12.Such as
Shown in Fig. 1, flexible parent metal 10 can include first area and second area.Touch control electrode layer 11 is located on flexible parent metal 10.Together
When, protective layer 12 covers touch control electrode layer 11.Herein, first area can be that touch-control sensitivity is relative in flexible display panels
Relatively low region, and second area can be then the region that touch-control sensitivity is of a relatively high in flexible display panels.Herein, it is soft
Property base material 10 can be the substrate of flexible display panels, such as the underlay substrate made of polyimide material.Flexible parent metal 10 is also
Can be a certain film layer inside flexible display panels, such as transparent planar layer.Touch control electrode layer 11 is used to realize touch controllable function.
Position of touch is determined by detecting the touch-control sensing signal of touch control electrode layer 11.And protective layer 12 is usually located at Flexible Displays
The upper surface (surface i.e. for finger contact) of panel, for obstructing aqueous vapor to prevent the film layer quilt inside flexible display panels
Corrosion, so as to extend the service life of flexible display panels.Protective layer 12 can be (but are not limited to) by organic material film laye with
The alternately laminated composition of inorganic material film layer.
Now, in order to reduce the difference of touch-control sensitivity between first area and second area, in touch control electrode layer 11, position
At least part touch control electrode in first area is less than to the distance L1 of the upper surface of protective layer 12 to be touched positioned at each of second area
Electrode is controlled to the distance L1 ＇ of the upper surface of protective layer 12.Wherein, upper surface is the surface away from flexible parent metal in protective layer.
It is understood that there is the distance of caused electric capacity with contact area and between the two between touch control electrode and finger
Close.In the case that distance between touch control electrode and finger is constant, if the contact area of first area and finger is relatively small,
Caused electric capacity between the touch control electrode of first area and finger can be made to diminish, so as to cause the touch-control sensitivity of first area low
In the touch-control sensitivity of second area.And the flexible display panels in the application are by reducing the touch control electrode in first area extremely
The distance between touch control electrode and finger in the distance of protective layer upper surface, i.e. reduction first area, to make up touch-control area
Capacitance difference caused by difference.It should be noted that protective layer is generally the film layer that flexible display panels directly contact with finger, hand
Finger can carry out touch control operation by the upper surface with protective layer.
In some optional implementations of the present embodiment, first area can be the marginal zone of flexible display panels
Domain, the i.e. intersection of touch-control viewing area and non-display area.Second area can be the non-edge of flexible display panels, that is, remove
Touch-control viewing area beyond intersection.
The present embodiment other alternatively in implementation, first area can be bent area domain, i.e. Flexible Displays
Curvature portion in panel.Second area can be non-bending region, i.e., non-curved part (such as plane in flexible display panels
Part).Curvature portion said herein can be that fixed curved surface or flexible display panels occur to fold formed curved surface
(curved surface i.e. under particular state).Due between the contact area between bending region and finger and non-bending region and finger
Contact area is compared to smaller, so there is also difference for the touch-control sensitivity between bending region and non-bending region.Pass through reduction
The touch control electrode in region is bent to the distance of the upper surface of protective layer, capacitance difference caused by touch-control area difference can also be made up,
So as to reduce the touch control detection sensitivity difference between bending region and non-bending region.
Alternatively, the flexible display panels in the application can be complementary surface panel.That is, the viewing area of the panel
There is no planar section.Such as the viewing area of flexible display panels is sphere (i.e. each point has the common center of circle).It is for example flexible again
The cross section of display panel is curve, and longitudinal section is straight line.Now first area can be the fringe region of curved surface panel, the
Two regions are the non-edge of curved surface panel.Specific division of the application to first area and second area does not limit.
Touched in addition, the flexible display panels in the application can be mutual capacitance type touch-control display panel or self-tolerant
Control display panel.And by various modes at least part touch control electrode positioned at first area can be realized to protective layer
The distance L1 of upper surface is less than the distance L1 ＇ for being located at each touch control electrode of second area to the upper surface of protective layer.Specifically can be with
Referring to Fig. 2-Figure 10.
As shown in Fig. 2 it illustrates the structural representation of one embodiment of the flexible display panels of mutual capacitance type touch-control.This
Flexible display panels in embodiment equally include flexible parent metal 10, touch control electrode layer 11 and protective layer 12.
In the present embodiment, touch control electrode layer 11 can include the first touch control electrode layer 111 and second touch control electrode layer
112.In second touch control electrode layer 112, distance of the second touch control electrode to the upper surface of protective layer 12 positioned at first area is small
Distance in the second touch control electrode positioned at second area to the upper surface of protective layer 12.
In the present embodiment, due to the first touch control electrode and second touch control electrode be respectively used to receive touch-control drive signal and
Send touch-control sensing signal, i.e. the first touch control electrode be touch-control emission electrode and touch-control sensing electrode in one kind, the second touch-control
Electrode is the another kind in touch-control emission electrode and touch-control sensing electrode.So between the first touch control electrode and second touch control electrode
Want mutually insulated.As shown in Fig. 2 it is provided with the first insulating barrier between the first touch control electrode layer 111 and second touch control electrode layer 112
21.And first touch control electrode layer 111 be located between the insulating barrier 21 of flexible parent metal 10 and first.Now, in order that being located at the firstth area
The upper surface of the second touch control electrode distance protection layer in domain is closer to the thickness P1 that the first insulating barrier 21 is located at first area can be big
It is located at the thickness P1 ＇ of second area in the first insulating barrier 21.Meanwhile in order that the second touch control electrode of first area to protective layer
The distance of 12 upper surface be less than second area second touch control electrode to the upper surface of protective layer 12 distance, protective layer 12
Upper surface can be the flat surfaces shown in Fig. 2 (i.e. in same level), or non-planar surface.Such as first
The upper surface of the protective layer in region to the height of flexible parent metal is less than the upper surface of the protective layer of second area to flexible parent metal
Highly.That is, there is difference in height in protective layer in first area and second area.Certainly, if protection positioned at first area
The thickness of layer 12 is more than the thickness of the protective layer 12 positioned at second area, and both thickness differences are less than the difference between P1 and P1 ＇
When being worth (absolute value), it can also equally meet the upper surface of second touch control electrode distance protection layer 12 of first area compared to the
The second touch control electrode distance in two regions closer to.That is, the thickness difference of protective layer is not enough to make up the thickness of the first insulating barrier
Degree is poor.
It should be noted that in mutual capacitance type touch-control display panel, typically according to the induced signal of touch-control sensing electrode
To determine position of touch.Herein, if second touch control electrode is touch-control sensing electrode, i.e., second touch control electrode is located at finger and
Between one touch control electrode.So advantageously reduce interfering between three, be easy to detect touch-control sensing electrode and finger it
Between electric capacity, and the mutual capacitance between touch-control sensing electrode and touch-control emission electrode, improve touch control detection precision.
It is understood that although the thickness increase of the first insulating barrier 21 in first area, can reduce first area
In second touch control electrode and the distance between finger, but can influence between the first touch control electrode and second touch control electrode simultaneously
Mutual capacitance.In order to make up the influence, it can increase by the first touch control electrode with second touch control electrode first by various modes
The area of overlapping region in region.Such as change the shape of the first touch control electrode and/or second touch control electrode in first area
Shape, size etc..
With continued reference to Fig. 3, the first touch control electrode layer 111 can be set with second touch control electrode layer 112 with layer.Now, together
Each first touch control electrode of row or same column can realize electrical connection by bridge mode.Or each the second of same column or colleague touches

In the present embodiment, flexible display panels can include bridge signal line layer 13.And bridge signal line layer 13 is with touching
Be provided between control electrode layer 11 second insulating barrier (such as the second insulating barrier 22 as shown in Fig. 4 a- Fig. 4 c, wherein, Fig. 4 a- Fig. 4 c
The flexible display panels structural representation of respectively three kinds mutual capacitance type touch-controls).In first touch control electrode layer 111, positioned at colleague's
Each first touch control electrode realizes electrical connection by the bridge signal wire of bridge signal line layer 13.It is understood that first in Fig. 3
The shape and relative position relation of touch control electrode and second touch control electrode are only schematical.And the flexibility of mutual capacitance type touch-control shows
Show that the concrete structure of panel may refer to Fig. 4 a- Fig. 4 c, it is sectional view of the flexible display panels in Fig. 3 in A-A ＇ directions.
It was found from from Fig. 4 a, bridge signal line layer 13 can be between the insulating barrier 22 of flexible parent metal 10 and second.Also
It is to say, no matter in first area or in second area, bridge signal line layer 13 is respectively positioned on the insulating barrier of flexible parent metal 10 and second
Between 22.Now, in order that the upper surface of the distance protection layer 12 of second touch control electrode 112 of first area is closer to so as to improve
The touch-control sensitivity of first area, the thickness P2 that the second insulating barrier 22 is located at first area can be located at more than the second insulating barrier 22
The thickness P2 ＇ of second area.And the upper surface of protective layer 12 equally can be flat surfaces or non-planar surface.
It was found from from Fig. 4 b, touch control electrode layer 11 can be between the insulating barrier 22 of flexible parent metal 10 and second.Namely
Say, no matter in first area or in second area, touch control electrode layer 11 (the first touch control electrode layer and second touch control electrode layer)
It is respectively positioned between the insulating barrier 22 of flexible parent metal 10 and second.Now, it is upper to protective layer 12 in order to reduce second touch control electrode 112
The distance on surface, the thickness P2 that the second insulating barrier 22 is located at first area can be located at second area less than the second insulating barrier 22
Thickness P2 ＇.And in order to simplify production technology, other film layers in addition to the second insulating barrier 22 can be according to common process
Made.
It was found from from Fig. 4 c, in first area, bridge signal line layer 13 can be located at the insulating barrier of flexible parent metal 10 and second
Between 22.In second area, touch control electrode layer 11 is located between the insulating barrier 22 of flexible parent metal 10 and second.So by changing the
The relative position relation between each layer in one region and second area, the phase of second touch control electrode 112 of first area can be made
Than in second area second touch control electrode 112 closer to the upper surface of protective layer 12, so as to improve the spirit of the touch-control of first area
Sensitivity, while the integral thickness of flexible display panels will not be had an impact.Now, in order to simplify production technology, bridge signal
The material of line, the first touch control electrode 111 and second touch control electrode 112 such as can be metal material with identical.Specifically, also
It is the conductive material between the insulating barrier 22 of flexible parent metal 10 and second, is to scheme corresponding to bridge signal line layer 13 in first area
Case, it is pattern corresponding to touch control electrode layer 11 in second area.
By adjusting touch control electrode in the film layer position of different zones, the touch-control effect reduced between different zones is realized
Difference, such as the touch-control difference on effect in bending region and non-bending region can be reduced.Simultaneously preferable does not change other films
The thickness of layer, or can be uniformly arranged each thicknesses of layers, simplify technique, ensure that the function of each film layer.
In addition, the structure of the flexible display panels of mutual capacitance type touch-control can also be as shown in Figure 5.Touched in first area, first
The 3rd insulating barrier 23 is provided between control electrode layer 111 and second touch control electrode layer 112.And first touch control electrode layer 111 be located at
Between the insulating barrier 23 of flexible parent metal 10 and the 3rd.That is, the first touch control electrode layer 111 and the second touch-control in first area
112 different layer of electrode layer is set.And in second area, the first touch control electrode layer 111 is set with second touch control electrode layer 112 with layer,
And between the insulating barrier 23 of flexible parent metal 10 and the 3rd.Wherein, the first touch control electrode in the first touch control electrode layer 111 passes through
Second bridge signal wire of the second bridge signal line layer 14 realizes electrical connection.3rd insulating barrier 23 is located at the second bridge signal line layer
Between 14 and touch control electrode layer 11.The second touch control electrode of first area can also so be reduced to the upper surface of protective layer 12
Distance, so as to improve the touch-control sensitivity of first area, and the integral thickness of flexible display panels is not interfered with.For the purposes of letter
Metaplasia production. art, the first touch control electrode, second touch control electrode and the second bridge signal wire can have identical material.
Alternatively, the second touch control electrode in second area, second touch control electrode layer 112 can be believed by the second bridge
Second bridge signal wire of number line floor 14 realizes electrical connection.So, the bearing of trend of the second bridge signal wire can be with the firstth area
The bearing of trend of the second touch control electrode in domain is identical.When same film layer is made using same material, the arrangement of pattern is more advised
Rule, be advantageous to improve production efficiency.
With further reference to Fig. 6, it illustrates the structural representation of one embodiment of the flexible display panels of self-tolerant touch-control
Figure.In the present embodiment, each touch control electrode in touch control electrode layer 11 receives touch-control drive signal, and sends touch-control sensing letter
Number.That is, produce self-capacitance between each touch control electrode and public electrode (equivalent to ground) before touch-control.When finger touch arrives
During panel, caused electric capacity can influence the self-capacitance of itself between the touch control electrode near finger and touch point.Such basis
The change of self-capacitance can determine position of touch before and after touch-control.
As shown in fig. 6, touch control electrode layer 11 can include the 3rd touch control electrode layer 113 and the 4th touch control electrode layer 114.And
The 4th insulating barrier 24 is provided between 3rd touch control electrode layer 113 and the 4th touch control electrode layer 114.4th insulating barrier 24 is positioned at the
The thickness P4 in one region can be less than the thickness P4 ＇ that the 4th insulating barrier 24 is located at second area.It can so reduce positioned at the 4th
The touch control electrode (touch control electrode in such as Fig. 6 in the 3rd touch control electrode layer 113 of flexible parent metal 10) of the lower section of insulating barrier 24
To the distance of protective layer 12.And other film layers can be made according to existing process, can so reduce to existing production
The influence of technological process, so as to reduce cost caused by technique adjustment.
Alternatively, the 3rd touch control electrode layer and the 4th touch control electrode layer can also be set with layer.And each touch control electrode can
To be electrically connected with least one touching signals line.Now, if being provided with insulating barrier between touch control electrode layer and touching signals line layer,
In order to reduce the touch control electrode of first area to the distance of protective layer, can also by change insulating barrier in first area and/or
The thickness of second area, or relative position of the touch control electrode layer in flexible display panels is adjusted to realize.Specifically it is referred to
Associated description in above-mentioned Fig. 4 a- Fig. 4 c, here is omitted.
For the flexible display panels in the various embodiments described above, first can also be improved by following at least one mode
The touch-control sensitivity in region.
The thickness of the touch control electrode in touch control electrode layer can be adjusted.As an example, in touch control electrode layer, close to protective layer
Touch control electrode in, the touch control electrode positioned at second area is more than positioned at the thickness of at least part touch control electrode of first area
Thickness.Herein, at least part touch control electrode can be the touch-control sensing electrode in the flexible display panels of mutual capacitance type touch-control,
Can be self-tolerant touch-control flexible display panels in touch control electrode.And each touch control electrode in touch control electrode layer can be same
Layer is set, can also different layer setting.As shown in fig. 7, set between the first touch control electrode layer 111 and second touch control electrode layer 112
There is the first insulating barrier 21.Now because second touch control electrode layer 112 is close to protective layer 12, so the second touch-control electricity of first area
The thickness L2 of pole can be more than the thickness L2 ＇ of the second touch control electrode of second area.And the upper surface of protective layer 12 can with but
It is not limited to flat surfaces.It should be noted that the increase with the thickness of touch control electrode may be to flexible display panels
Bending produces certain influence, so the thickness of touch control electrode can not be adjusted infinitely.
In addition, as shown in figure 8, protective layer 12 can also be made, which to be located at the thickness L3 of first area, is less than protective layer 12 positioned at the
The thickness L3 ＇ in two regions.In application scenes, if protective layer 12 is bonded with flexible parent metal 10 by optical cement layer,
The touch-control sensitivity of first area now can also be improved by changing the thickness of optical cement layer.Specifically as shown in figure 9, light
The thickness L4 that glue-line 15 is located at first area is less than the thickness L4 ＇ that optical cement layer 15 is located at second area.Both modes exist
While improving the touch-control sensitivity of first area, other film layers can be made according to existing process, it is possible to reduce to existing
There is the influence of production technology, while ensureing each film layer function, reduce production cost, and contribute to the thin of flexible display panels
Typeization designs.
Alternatively, flexible display panels can also include the 5th insulating barrier between touch control electrode layer and protective layer.This
When, because the 5th insulating barrier is located at the top of touch control electrode layer, i.e., close to protective layer, if so the 5th insulating barrier is located at the firstth area
The thickness in domain is less than the thickness that the 5th insulating barrier is located at second area, can also improve the touch-control sensitivity of first area.And
Other film layers can be made according to existing process, it is possible to reduce the influence to existing production technology, ensure each film layer function
While, reduce production cost.
In certain embodiments, as shown in Figure 10, flexible display panels can also include the 6th insulating barrier 26.6th insulation
Layer 26 is between flexible parent metal 10 and touch control electrode layer 11.And the 6th insulating barrier 26 be only arranged at first area.So with
The touch control electrode in two regions is compared, and each touch control electrode of first area can be integrally close to the upper surface of protective layer 12, so as to
Improve the touch-control sensitivity of first area, and the influence to the production technology of existing each film layer is smaller, ensures each film layer function
While, reduce production cost.
Further, flexible display panels can also include the four-line poem with seven characters to a line edge between flexible parent metal and touch control electrode layer
Layer.Now, because four-line poem with seven characters to a line edge layer is located at the lower section of touch control electrode layer, i.e., away from protective layer, if so four-line poem with seven characters to a line edge layer is located at
The thickness of first area is more than the thickness that four-line poem with seven characters to a line edge layer is located at second area, and the touch-control that can equally improve first area is sensitive
Degree.
Present invention also provides a kind of display device.The display device can include soft described in the various embodiments described above
