The sub-pixel 60 is illustrated the display panel for providing data-signal.
On the basis of the above embodiments, in one embodiment of the invention, the multiple sub-pixel is divided into multiple
Along the pixel column of preset direction arrangement.Since the viewing area of the display panel is when bending, bent-axis can
With the non-open region between the adjacent subpixels in the viewing area, shown with the bent-axis is reduced as far as possible to described
Show the influence of the display picture of panel.
Specifically, in one embodiment of the invention, the multiple pixel column along preset direction arrangement divides
At M pixel group, each pixel group includes N number of sub-pixel；Wherein, the first electrode 21 on the flexible base board 10 just
Projection is located at gap of the adjacent pixel group between the orthographic projection on the flexible base board 10.It should be noted that at this
In inventive embodiments, M is any positive integer not less than 1, and N is any positive integer not less than 1.
It should be noted that N is smaller, the first electrode number of segment and second electrode number of segment for including in a data line
Number is more, and the possibility that the data line is broken is smaller, but correspondingly, the composition electrode section in the data line is more,
The resistance of the data line is also bigger.For an extreme example, for example, the first electrode number of segment that includes when the data line and
When second electrode number of segment tends to be infinite, then the data line is considered as being made of numerous point, then the data line is flexible
Property is considered as that any position is bent, correspondingly, the length of the first electrode and the second electrode is smaller, described
The manufacture craft difficulty of one electrode and the second electrode is also bigger.
For the probability that the technology difficulty of the balanced data line and the data line are broken, specifically, at this
In one embodiment of invention, N 3, as shown in figure 9, the multiple pixel column along preset direction arrangement is divided into M
Pixel group 70, each pixel group 70 include 3 sub-pixels, i.e., each pixel group 70 includes the first sub-pixel 61, the second sub- picture
Element 62 and third sub-pixel 63；Wherein, orthographic projection of the first electrode 21 on the flexible base board 10 is located at adjacent described
Gap of the pixel group 70 between the orthographic projection on the flexible base board 10.
It should be noted that since the gap in the display panel between adjacent subpixels is smaller, and the display surface
Gap in plate between adjacent subpixels is smaller, and orthographic projection of the first electrode 21 on the flexible base board 10 is located at adjacent
When gap of the pixel group between the orthographic projection on the flexible base board 10, length of the second electrode 22 along preset direction
Spend smaller, the manufacture craft difficulty of the second electrode 22 is bigger, therefore, in one embodiment of the invention, in order to reduce
The technology difficulty of the second electrode 22, the gap between sets of adjacent pixels are greater than in same pixel group between adjacent subpixels
Gap, under the premise of the resolution ratio of the display panel is constant, by reducing in same pixel group between adjacent subpixels
Gap, to increase the gap between sets of adjacent pixels, to reduce the technology difficulty of the first electrode 21.
Optionally, the gap in same pixel group between adjacent subpixels is equal, arbitrary neighborhood two in multiple pixel groups

Based on any of the above embodiments, in one embodiment of the invention, the flexible base board 10 is single layer
Structure, as shown in Figure 10, the flexible base board 10 include the first film 11, also only include the first film 11.Implement in the present invention
In example, the first metal layer is located at the 11 first area surface of the first film, i.e., the described first electrode 21 is positioned at described the
The surface of one film, 11 first area.
In another embodiment of the present invention, the flexible base board 10 is multilayered structure, i.e., the described flexible base board 10 wraps
Include at least double-layer films.By taking the flexible base board 10 includes double-layer films as an example, as is illustrated by figs. 11 and 12, the flexible base board
10 not only include the first film 11, further include positioned at the first film 11 away from the metal layer side buried layer 12 and
Deviate from the second film 13 of 11 side of the first film positioned at the buried layer 12.In embodiments of the present invention, described first
Metal layer can be located at second film 13 and deviate from 11 side of the first film, can also be located at the first film 11 with
It between the buried layer 12, may be located between second film 13 and the buried layer 12, i.e., the described first electrode 21
Second film 13 can be located at and deviate from 11 side of the first film (as shown in figure 11), it is thin that described first can also be located at
Between film 11 and the buried layer 12 (as shown in figure 12), it may be located between second film 13 and the buried layer 12
(as shown in figure 13), the present invention to this and without limitation, specifically depend on the circumstances.
Optionally, the first film 11 is identical with the material of second film 13, and the first metal layer is located at institute
It states between the first film 11 and the buried layer 12, or between second film 13 and the buried layer 12, in institute
In the bending process for stating display panel viewing area, the first film 11 be applied to the first electrode 21 partial action power and
Second film 13 is applied to 21 top of first electrode and is allocated as firmly offseting, and further decreases the first electrode 21
The probability being broken extends the service life of the display panel.
In addition, the display panel further include: deviate from the planarization layer etc. of the metal layer side positioned at the sub-pixel
Structure, since it has been well known to those skilled in the art, this is no longer described in detail in the present invention.
To sum up, in display panel provided by the embodiment of the present invention, the first metal layer includes multiple first electrodes, institute
Stating second metal layer includes multiple second electrodes, and on preset direction, and the adjacent second electrode passes through the first electrode
Electrical connection, i.e., be divided into multiple electrodes section for each metal wire extended along preset direction (perpendicular to the extending direction of bent-axis),
Adjacent electrode segments along preset direction are electrically connected by another electrode section being arranged with its different layer, thus in the display panel
When viewing area is bent along bent-axis, the tensile stress that the first electrode is subject to can be released by it along the both ends of preset direction
Put and/or the second electrode on the tensile stress that is subject to can be discharged by it along the both ends of preset direction, avoid described the
The stress being subject on one electrode and/or the second electrode is excessive to be broken, and then is avoided in the display panel along default
The metal wire that direction extends is broken, and guarantees the normal display of the display panel, and extend the display panel uses the longevity
Life.
Various pieces are described in a progressive manner in this specification, and what each some importance illustrated is and other parts
Difference, same and similar part may refer to each other between various pieces.
The foregoing description of the disclosed embodiments enables those skilled in the art to implement or use the present invention.
Various modifications to these embodiments will be readily apparent to those skilled in the art, as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, of the invention
It is not intended to be limited to embodiment illustrated herein, and is to fit to consistent with the principles and novel features disclosed in this article
Widest scope.
