Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
In the prior art, as shown in Figure 1, encapsulation film layer 400 included by the dot structure of flexible display substrates is inorganic
Film layer is encapsulated, after flexible display substrates are formed on the glass substrate, it is difficult to the glass flexibility display base plate from glass substrate.Hair
Bright people's discovery: luminescent device and thin film transistor (TFT) for the thickness of inorganic encapsulated film layer, in flexible base board 100
Thickness than relatively thin so that flexible display substrates are formed in after glass substrate 001 ', although inorganic encapsulated film layer and glass base
There are also luminescent device and thin film transistor (TFT)s between plate 001 ', but luminescent device and thin film transistor (TFT) can be ignored, this
When inorganic encapsulated film layer to the region of strain stretch adjustment hole 101 and glass substrate 001 ' it is believed that being in contact condition；And due to
Glass substrate 001 ' is made with inorganic encapsulated film layer by inorganic material, so that inorganic encapsulated film layer is to strain stretch adjustment hole
Part it is stronger with the binding force of glass substrate 001 '；Therefore, by glass substrate 001 ' from flexible display substrates to strain stretch
When the region removing of adjustment hole 101, need bigger peel force, and this but also in Fig. 2 arrow meaning position (bridge zone,
Connect the region of two stretching adjustment holes) it is easy to happen extensive disruption, cause the production yield of flexible display substrates to decline.
In view of the above-mentioned problems, the embodiment of the invention provides a kind of dot structure, the pixels as shown in Fig. 3, Fig. 4 and Fig. 7
Structure includes flexible base board 100 and the pixel defining layer 300 for being formed in 100 surface of flexible base board；Flexible base board 100 offers
First stretches adjustment hole 110, and pixel defining layer 300 includes the removing adjustment portion 310 in the first stretching adjustment hole 110, stripping
It include at least two second stretching adjustment holes 311 from adjustment portion 310.
It is understood that above-mentioned dot structure further includes encapsulation film layer 400, which defines positioned at pixel
300 surface far from flexible base board 100 of layer, encapsulation film layer 400 cover flexible base in the orthographic projection of 100 place plate face of flexible base board
Plate 100 and first stretches adjustment hole 110.
Based on above-mentioned dot structure it is found that above-mentioned flexible base board 100 offers the first stretching adjustment hole 110, pixel is defined
Layer 300 includes stretching removing adjustment portion 310 in adjustment hole 110 to being located at first, and inorganic envelope can be increased by removing adjustment portion 310
The distance between film layer 400 and glass substrate are filled, so that possessed structure between inorganic encapsulated film layer 400 and glass substrate
Thickness is difficult to ignore.And due to pixel defining layer 300 using organic material (such as polyimides, but be not limited only to this) make and
At glass substrate is made using inorganic material (such as silica), so that between glass substrate and pixel defining layer 300
Binding force is weaker, therefore, when glass substrate stretches the position glass of adjustment hole 110 from flexible display substrates corresponding first, institute
The peeling force needed is smaller, can thus reduce between the two first stretching adjustment holes 110 that flexible base board 100 is opened up
The fracture possibility of bridge zone so that flexible display substrates are easy to remove from glass substrate, and then improves flexible display substrates
Production yield.Meanwhile above-mentioned removing adjustment portion 310 includes at least two second stretching adjustment holes 311, so that removing adjustment portion
310 there is good stretch function to remove adjustment portion in this way when first, which stretches, is equipped with removing adjustment portion 310 in adjustment hole 110
310 will not generate large effect to the stretch function of flexible base board 100.
It is appreciated that above-mentioned at least two second stretch adjustment hole 311 in the positive throwing of 100 place plate face of flexible base board
The gross area of shadow is the first stretching adjustment hole 110 the 5%~15% of the area of 100 place plate face of flexible base board；At this point, making
It, can either be in the feelings that flexible display substrates do not produce fracture when making containing flexible display substrates included by above-mentioned dot structure
Glass substrate is readily removed under condition, and the tensile property of flexible display substrates can be guaranteed not by excessive influence.
In some embodiments, as shown in fig. 7, the axial direction for stretching adjustment hole 110 when first and second stretches adjusting
When the axial direction difference in hole 311, flexible display substrates applied by dot structure can be made generated during stretching
Internal stress is bigger.Based on this, above-mentioned first, which stretches the axial direction of adjustment hole 110 and each second, stretches adjustment hole 311
Axial direction is identical, so that the first stretching for stretching adjustment hole 110 adjusts the stretching tune that direction stretches adjustment hole 311 with second
It is identical to save direction, such first stretching adjustment hole 110 and the second stretching adjustment hole 311 match, and reduce flexible display substrates and exist
Generated internal stress in drawing process, the stretch function to guarantee flexible display substrates are best.
In some embodiments, as shown in Figure 3 and Figure 4, above-mentioned pixel defining layer 300 further includes being formed in flexible base board
Portion 320 is defined at the top of 100 surfaces.It defines portion 320 and can be structure as a whole with above-mentioned removing adjustment portion 310 or independent in the top
Structure.
When portion 320 is defined at top and removing adjustment portion 310 is structure as a whole, the production of pixel defining layer 300 can be facilitated；
When portion 320 is defined at top and above-mentioned removing adjustment portion 310 is absolute construction, if above-mentioned dot structure is applied to Flexible Displays
Substrate, during stretching flexible display substrates, top is defined will not mutually tear between portion 320 and removing adjustment portion 310,
So that the tensility of removing adjustment portion 310 can be more preferable.
Such as: as shown in Figure 3 and Figure 7, when above-mentioned removing adjustment portion 310 opens up two second stretching adjustment holes 311, two
A second stretching, 311 one side of adjustment hole may make removing adjustment portion 310 to be divided into independent two parts, and a part can connect with hole wall
Touching, when making flexible display substrates, another part is contacted with underlay substrate 001.Made flexible display substrates exist in this way
When stretching, the part contacted with hole wall will not be torn and another part, to guarantee to remove the influence that adjustment portion 310 will not be excessive
The influence of the tensile property of flexible base board 100.
Certainly, as shown in figs. 4 and 7, when above-mentioned removing adjustment portion 310 opens up four second stretching adjustment holes 311, on
State removing adjustment portion 310 close to first stretching 110 side wall of adjustment hole two second stretching adjustment holes 311 equally can be achieved it is above-mentioned
Removing adjustment portion 310 opens up two second effects achieved of stretching adjustment hole 311.
In some embodiments, as shown in Fig. 3, Fig. 4 and Fig. 7, above-mentioned dot structure further includes being located at 100 table of flexible base board
