Embodiment 1:
As depicted in figs. 1 and 2, wherein do not regard out luminescence unit 20 and signal wire 30 in Fig. 1 a, Fig. 2 a and Fig. 2 b.
The present embodiment provides a kind of display base plates, and including substrate 10, the display structure of formation on the substrate 10, substrate 10 has
There are the multiple openings 13 for being connected to its top and bottom, and substrate 10 is made of deformable material.
Wherein, display structure refers to the structure for realizing display, may include that (i.e. sub-pixel, can for luminescence unit 20
Including pixel electrode etc.) and connection luminescence unit 20 signal wire 30, the wherein array distribution on the substrate 10 of luminescence unit 20, letter
Number line 30 may include connecting the grid line of luminescence unit 20 in the row direction and connecting luminescence unit 20 in a column direction
Data line.Luminescence unit 20 and signal wire 30 are located at the non-opening of the top surface of substrate 10.
Wherein, it should be understood that line direction and column direction are that two in display base plate intersect direction, are not represented
It must be respectively cross direction profiles and genesis analysis, such as line direction and column direction when display base plate uses when display base plate use
It can be slanting.
Substrate 10 is made of deformable material flexible, such as polyimides organic material, therefore substrate 10 can occur one
Fixed deformation and can't damage.Certainly, substrate 10 can also have certain elasticity, i.e. certain stretching change is occurring for its material
It can be original shape by elastic recovery after shape.
In the display base plate of the present embodiment, due to having opening 13, therefore the astomous part of substrate 10 can utilize opening 13
Deformation occurs (not being substrate 10 itself by " elongation "), so that display base plate is stretchable on the whole；Wherein, due to base
Bottom 10 is mainly the deformation that display base plate entirety is realized by shape change rather than practical quilt " elongation ", therefore the practical quilt of substrate 10
The degree of " elongation " is much smaller than " elongations " degree of display base plate entirety, thus display structure thereon it is practical do not occur to extend (or
Elongation degree very little), it will not damage.So that the display base plate has stretchable performance, to expand the display base plate
Operation strategies.
Preferably, substrate 10 includes: multiple first parts 11, is in array distribution；Multiple second parts 12, at least partly phase
It is connected between adjacent Liang Ge first part 11 by least one second part 12, so as to be not connected with second between first part 11
The position of part 12 forms multiple openings 13.
Wherein, that is to say, if when being connected between adjacent Liang Ge first part 11 by second part 12, first
Part 11 is alternatively distributed with second part 12.
Multiple first parts 11 form entire substrate 10 by the connection of multiple second parts 12, so that substrate 10 is by two
When contrary power, it is easier to deform, be easier to be stretched so that display base plate is shown.
Preferably, in the row direction, connected between adjacent any two first part 11 by least one second part 12
It connects；In a column direction, it is connected between adjacent any two first part 11 by least one second part 12.
Wherein, that is to say, that each first part 11 of the end on column direction or column direction is at least connected with two
Second part 12, each first part 11 positioned at non-end are at least connected with four second parts 12.
This structure can be mutually matched with the distribution of the gate lines, data lines in signal wire 30, guarantee display base plate
Display performance under the premise of, the display base plate tensile property can be made more excellent.
Preferably, first part 11 is bulk, such as cylindrical body or cube, and second part 12 is curved strip,
When adjacent Liang Ge first part 11 is applied respectively be parallel to line between the two and contrary power when, in stress side
Connect up Liang Ge first part 11 second part 12 can deformation occurs so that between the first part 11 of two stress away from
From change.
Wherein, it when display base plate is by contrary external force, since second part 12 is opposite " relatively thin ", is easy to produce
Stress is concentrated, thus mainly second part 12 deformation occurs and " being straightened " or " press-bending ", and first part 11 hardly happens
Deformation.For example, in the row direction, when display base plate is by contrary external force (F1, F2 in such as Fig. 2 a), connection first
The second part 12 of part 11 gradually changes due to the effect of external force from curved strip to linear type, so that the second part
The distance of two positions of 12 connection first parts 11 becomes larger, i.e., between the first part 11 of the second part 12 connection
Distance becomes larger (a in such as Fig. 2 a and Fig. 2 b), to realize the stretching of entire display base plate.
The display base plate of this implementation is mainly the tensility that it is realized by the deformation of second part 12 in substrate 10
Can, therefore the deformation very little in first part 11, therefore by the way that main display structure to be set in first part 11, can further it subtract
Its small actual deformation.
Preferably, it is connected between at least partly adjacent Liang Ge first part 11 by two second parts 12, and two
Two parts 12 are symmetrical.
Wherein, two second parts 12 are that the symmetrical concave side that can be second part 12 is opposite, are also possible to
The convex side of two parts 12 is opposite.
It can guarantee drawing for display base plate by two connections of second part 12 between adjacent Liang Ge first part 11
Under the premise of stretching performance, reinforce the intensity of substrate 10, in order to avoid phenomena such as second part 12 is broken due to deformation fatigue, from
And extend the service life of display base plate.
Specifically, can judge second part according to angle between the side of first part 11 and the side of second part 12
12 deformation extent, as shown in Figure 2 a and 2 b, before stress the side of the side of first part 11 and second part 12 it
Between angle be θ, and angle theta becomes larger after stress, and the deformation journey of second part 12 can be judged according to the size that angle theta changes
Degree, can accurately control the deformation extent of second part 12 in this way, in order to avoid occur leading to second part since external force is excessive
12 damages.
Preferably, second part 12 is being greater than remaining position of second part 12 with the cross-sectional area of first part 11 junction
Cross-sectional area.
Wherein, display base plate is when by force-extension, since the deformation of first part 11 is far smaller than second part 12
Deformation, therefore stress can occur in the junction of first part 11 and second part 12 and concentrate, so that first part 11
It is easily damaged with the junction of second part 12 (as being broken).
Second part 12 is being greater than the transversal of 12 remaining position of second part with the cross-sectional area of first part 11 junction
Area, can be to avoid substrate 10 the phenomenon that the junction of first part 11 and second part 12 is easily damaged.
In addition, second part 12 can be the arcuation of not corner angle, can deformed in this way in order to avoid second part 12
During, there is certain of corner angle to be easily damaged since stress is concentrated.The size (its cross-sectional area) of second part 12 can
It concentrates and adjusts with the middle stress occurred according to the actual situation, stress is dispersed on entire second part 12, stress is avoided
It concentrates and region easy to damage occurs.
Preferably, substrate 10 is made of the deformable material of memory-type.
Wherein, the deformable material of memory-type can deformation occurs under the action of by external force, if external force disappears, and full
After the certain trigger condition (such as temperature, magnetic force, illumination) of foot, the shape to before stress can be restored.That is, display
After substrate is stretched, can be voluntarily replied under certain condition as original original state.
Preferably, luminescence unit 20 is formed in first part 11, and signal wire 30 is formed on second part 12.
Wherein, luminescence unit 20 may include multiple and different dot structures (such as R, G, B dot structure), can with each
One dot structure is set in a part 11, it can also be multiple dot structures be arranged in each first part 11.
On-deformable luminescence unit 20 is arranged in the first part 11 hardly deformed after stress, and by easy change
The setting of signal wire 30 of shape is deformed after stress on larger second part 12, can preferably guarantee stretchable display base plate
Display performance is not influenced by the deformation of substrate 10.
Certainly, the above only example, is not the restriction of concrete form.For example, the shape of first part 11 can be different, second
12 quantity of part, connection type can be different, but only one luminescence unit 20 in each first part 11, can also there is many shine
Unit 20 can also have luminescence unit 20 on second part 12, the multiple second parts 12 being connected between Liang Ge first part 11
