Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic structural diagram of a display panel according to an embodiment of the present invention. Specifically, fig. 1 is a schematic top view of a display panel according to an embodiment of the present invention. As shown in fig. 1, the display panel 1 provided by the embodiment of the present invention includes a stretchable substrate 10 and a display layer 20 disposed on the stretchable substrate 10. The display layer 20 includes a plurality of island-shaped display units 21 each independently forming an island and arranged in an array, and the display layer 20 further includes a plurality of connection units 22. Each of the connection units 22 electrically connects two adjacent island-shaped display units 21, and when the display panel 1 is stretched, the connection unit 22 can rotate around the connection point of the island-shaped display unit 21 and the connection unit 22.
As shown in fig. 1, the stretchable substrate 10 is a rectangular plate-shaped structure, the island-shaped display units 21 are rectangular plate-shaped structures including rounded corners, and the island-shaped display units 21 are smaller in size than the stretchable substrate 10. Alternatively, the material of the stretchable substrate 10 may be at least one of polymers such as polyimide, polycarbonate, polyethersulfone, polyethylene terephthalate, polyethylene naphthalate, polyarylate, or glass fiber reinforced plastic.
Specifically, the arrangement state of the plurality of island-like display units 21 included in the display layer 20 shown in fig. 1 is in an unstretched state, that is, the display panel 1 is not stretched. Each of the connection units 22 has a linear strip structure including a first connection end 221 and a second connection end 222. The connecting unit 22 is used to electrically connect two adjacent island-shaped display units 21, and any two adjacent island-shaped display units 21 are electrically connected by a corresponding connecting unit 22. Wherein the first connection terminal 221 of the connection unit 22 is electrically connected to one of the adjacent two island-shaped display units 21, and the second connection terminal 222 of the connection unit 22 is electrically connected to the other of the adjacent two island-shaped display units 21. For example, as shown in fig. 1, the island-shaped display unit 21 corresponding to the mark a and the island-shaped display unit 21 corresponding to the mark B are adjacent two island-shaped display units 21. A connecting unit 22 is arranged between the island-shaped display unit 21 corresponding to the mark a and the island-shaped display unit 21 corresponding to the mark B, the first connecting end 221 of the connecting unit 22 is electrically connected with the island-shaped display unit 21 corresponding to the mark a, and the second connecting end 222 of the connecting unit 22 is electrically connected with the island-shaped display unit 21 corresponding to the mark B.
In the embodiment of the present invention, the connection unit 22 between any two adjacent island-shaped display units 21 can rotate about the connection point between the island-shaped display unit 21 and the connection unit 22 when the display panel 1 is stretched.
In addition, it should be noted that, for the sake of simplicity and clarity of the drawings, some of the same components (such as the island-shaped display units 21) are only exemplarily marked with one or more reference numbers, and those skilled in the art can clearly distinguish the components in the drawings according to the shapes of the components, the filling patterns and the corresponding text descriptions of the drawings.
According to the display panel provided by the embodiment of the invention, the purpose of relieving the tensile force by the rotating connecting unit is realized by limiting the mode that the connecting unit rotates by taking the connecting point of the island-shaped display unit and the connecting unit as the center when the display panel is stretched. Compared with the prior art, the embodiment of the invention can effectively reduce the possibility that the structures such as the connecting units corresponding to the island-shaped display units are damaged in the stretching process, thereby improving the reliability of the display panel and the display device comprising the display panel.
It should be understood that the island-shaped display unit 21 is not limited to the rectangular plate-shaped structure including the circular-arc corners mentioned in the above embodiment, but may be a circular plate-shaped structure, an elliptical plate-shaped structure, a diamond plate-shaped structure, or the like, which is not limited by the embodiment of the present invention.
It should be noted that the arrangement of the island-shaped display units included in the display layer may also be an irregular arrangement, which is not uniformly limited in the embodiment of the present invention.
The meaning of the connection unit rotating around the connection point of the island-shaped display unit and the connection unit when the display panel is stretched in one embodiment of the present invention will be described in detail with reference to fig. 2 and 3.
Fig. 2 is a schematic structural diagram of a display layer in a compressed state according to an embodiment of the present invention. Fig. 3 is a schematic structural diagram of a display layer in a stretched state according to an embodiment of the present invention. Specifically, fig. 2 and 3 show the structure of the display layer 20 in the broken line region M in the display panel 1 shown in fig. 1. For ease of explanation, fig. 2 and 3 only select the display layer 20 within the dashed area M. In addition, the connection units 22 that are not related to the island-shaped display units 21 within the dotted line region M have been deleted for clarity of display.
As shown in fig. 2, the display panel 1 is in an unstretched state, and accordingly, the arrangement state of the island-shaped display units 21 included in the display layer 20 is in an unstretched state. As shown in fig. 3, fig. 3 is a display layer 20 in a stretched state formed by completely stretching and unfolding the display layer 20 shown in fig. 2.
In the actual stretching process, the angle of rotation of the connection unit 22 around the connection point of the island-shaped display unit 21 and the connection unit 22 is greater than 0 ° and less than 90 °. When the display layer 20 is stretched in two diagonal directions to the fully stretched state shown in fig. 3, the line connecting the first connection terminal 221 and the second connection terminal 222 of the connection unit 22 is perpendicular to the side edge of the island-shaped display unit 21.
Further, in the embodiment of the present invention, in order to ensure that the connection unit 22 can rotate around the first connection end 221 and the second connection end 222 when the display panel 1 is stretched, and avoid causing the connection unit 22 to be stretched and broken or cracked during the stretching of the display panel 1, an included angle (an included angle a and an included angle b shown in fig. 2 and 3) between a projection of at least one of two adjacent sides of two adjacent island-shaped display units 21 on the stretchable substrate and a projection of a connection line of the first connection end 221 and the second connection end 222 on the stretchable substrate is greater than 0 ° and less than 90 °.
The display panel 1 according to the embodiment of the present invention, based on the above-mentioned specific arrangement relationship between the connection units 22 and the island-shaped display units 21, achieves the purpose of relieving the tensile force applied to the connection units 22 themselves by the connection units 22 that are rotatable with respect to the island-shaped display units 21, thereby reducing the risk of breaking the connection units 22. Specifically, the embodiment of the present invention can reduce the risk of breaking the connection unit 22 by alleviating the tensile force by the length of the rotatable connection unit 22 itself, regardless of whether the display panel 1 provided by the embodiment of the present invention is stretched in the lateral direction (the left-right direction of the orientation shown in fig. 2 and 3), or the display panel 1 provided by the embodiment of the present invention is stretched in the longitudinal direction (the up-down direction of the orientation shown in fig. 2 and 3), or the display panel 1 provided by the embodiment of the present invention is stretched in the diagonal direction (the rectangular diagonal direction of the orientation shown in fig. 2 and 3).
Preferably, the first connection end 221 and the second connection end 222 of the connection unit 22 are respectively located at two sides of a central line of two adjacent island-shaped display units 21, and preferably, the first connection end 221 and the second connection end 222 are respectively located at two adjacent sides of two adjacent island-shaped display units 21. For example, each side includes a first end and a second end, and the first ends of two adjacent sides are located on the same side of a connecting line between centers of two adjacent island-shaped display units 21, and the second ends of two adjacent sides are also located on the other side of the connecting line between centers of two adjacent island-shaped display units 21. Further, the first connection terminal 221 and the second connection terminal 222 of the connection unit 22 are arranged to be symmetrical with respect to the center of the middle point of the center connection line of the adjacent two island-shaped display units 21, so that the stretchability of the display panel 1 can be improved.
Fig. 4 is a schematic structural diagram of a display layer 20 in an unstretched state according to another embodiment of the present invention. The embodiment shown in fig. 4 is extended based on the embodiment shown in fig. 1 of the present invention, and the differences between the embodiment shown in fig. 4 and the embodiment shown in fig. 1 will be emphasized below, and the descriptions of the same parts will not be repeated.
As shown in fig. 4, in the display layer 20 provided in the embodiment of the present invention, any two adjacent island-shaped display units 21 have a symmetry axis (i.e., symmetry axes S1 to S4) in common. The first connection end 221 and the second connection end 222 of the connection unit 22 between two adjacent island-shaped display units 21 are respectively located on different sides of the symmetry axis corresponding to the two adjacent island-shaped display units 21.
In the embodiment of the present invention, the first connection end 221 and the second connection end 222 of the connection unit 22 are respectively disposed at different sides of the symmetry axis corresponding to the two adjacent island-shaped display units 21, so that the stress equalization degree of the display panel is effectively improved, and the display panel can still maintain a good display effect when being stretched under the action of an external force.
Another embodiment of the present invention is extended from the embodiment shown in fig. 4. In the embodiment of the present invention, the first connection end 221 and the second connection end 222 of the connection unit between two adjacent island-shaped display units 21 are respectively located in the preset corner regions on different sides of the symmetry axis corresponding to the two adjacent island-shaped display units 21. For example, the island-shaped display unit 21 has a rectangular plate-shaped structure including circular arc corners, and correspondingly, the predetermined corner area is a predetermined range area of the circular arc corners. Compared with the embodiment shown in fig. 4, the embodiment of the invention not only can further improve the stress equalization degree of the display panel, but also can further increase the stretching degree of the display panel.
Fig. 5 is a schematic structural diagram of a display layer in an unstretched state according to another embodiment of the present invention. The embodiment shown in fig. 5 is extended based on the embodiment shown in fig. 4 of the present invention, and the differences between the embodiment shown in fig. 5 and the embodiment shown in fig. 4 will be emphasized below, and the descriptions of the same parts will not be repeated.
As shown in fig. 5, in the display layer 20 provided in the embodiment of the present invention, the first connection end 221 and the second connection end 222 of the connection unit 22 between two adjacent island-shaped display units 21 are respectively located on the same side of the symmetry axis corresponding to the two adjacent island-shaped display units 21.
In the embodiment of the present invention, by respectively disposing the first connection end 221 and the second connection end 222 of the connection unit 22 on the same side of the symmetry axis corresponding to the two adjacent island-shaped display units 21, on the premise of ensuring that the tensile force can be relieved by the self length of the connection unit 22 having the rotation capability, the structural arrangement diversity of the display layer 20 is enriched.
In an embodiment of the present invention, the connection unit 22 is a rigid connection line having no elasticity and being linear. Preferably, the material of the rigid connection line comprises a conductive metal and/or graphene. Because the rigid connecting line can effectively prevent the space between the island-shaped display units 21 from sudden change in the stretching process, and when the display panel 1 is completely stretched to the stretching state, the space between each adjacent island-shaped display units is also equal, and therefore, the rigid connecting line can effectively ensure the display effect of the display panel 1.
In another embodiment of the present invention, the connection unit 22 is an elastic connection line. Compared with a rigid connecting wire, the elastic connecting wire has better tensile extensibility, and the tensile reliability of the display panel can be further improved by means of the elastic connecting wire. Illustratively, the material of the elastic connection line is a conductive polymer material, such as conductive plastics like polyacetylene, polyphenylacetylene, and the like. Preferably, the material of the elastic connection line is conductive rubber. The conductive rubber can be prepared by mixing conductive metal particles into silicone rubber, so that the conductive rubber has good conductivity and stretchability.
In another embodiment of the present invention, when the display panel 1 is stretched, the stretching distance between the island-shaped display units 21 in the edge area of the display panel 1 is large because the stretching force received by the edge area of the display panel 1 is larger than the stretching force received by the middle area of the display panel 1, which may cause the connecting units 22 in the edge area of the display panel 1 to crack or break. Therefore, in the edge area of the display panel 1, for example, at the corner or side position of the display panel 1, the material of the connection unit 22 is elastic, and correspondingly, the material of the connection unit 22 in the middle area of the display panel 1 is rigid. So set up, under the prerequisite of guaranteeing display panel 1 middle zone island display element 21 tensile degree, fracture or crackle appear in the linkage unit 22 that can avoid display panel 1 edge region, and then promote display panel 1's tensile reliability.
Fig. 6 is a schematic structural diagram of a display layer 20 in an unstretched state according to still another embodiment of the present invention. The embodiment shown in fig. 6 is extended based on the embodiment shown in fig. 1 of the present invention, and the differences between the embodiment shown in fig. 6 and the embodiment shown in fig. 1 will be emphasized below, and the descriptions of the same parts will not be repeated.
As shown in fig. 6, in the display panel provided by the embodiment of the present invention, the connection unit 22 included in the display layer 20 is a spiral-shaped elastic connection line.
Since the spiral elastic connection line has better stretchability than the linear connection line, the embodiment of the invention can further improve the stretching reliability of the display panel 1.
In another embodiment of the present invention, the number of the connecting units 22 between two adjacent island-shaped display units 21 is multiple, so as to further reduce the risk of the display panel failure caused by the fracture of the connecting units 22, and further improve the stretching reliability of the display panel.
Fig. 7 is a schematic structural diagram of a display layer 20 in an unstretched state according to still another embodiment of the present invention. The embodiment shown in fig. 7 is extended based on the embodiment shown in fig. 1 of the present invention, and the differences between the embodiment shown in fig. 7 and the embodiment shown in fig. 1 will be emphasized below, and the descriptions of the same parts will not be repeated.
As shown in fig. 7, in the embodiment of the present invention, the projected shape of the island-shaped display unit 21 on the stretchable substrate is a circle. That is, the island-shaped display unit 21 is a circular island-shaped display unit. In the embodiment of the present invention, the connection unit 22 is a straight line connection line, and the circle centers of two adjacent circular island-shaped display units 21 are connected with the straight lineThe included angle of the line connecting lines is more than 0 degree and less than 90 degrees. Specifically, a smaller angle between a circle center connecting line of two adjacent circular island-shaped display units 21 and a straight line connecting line is greater than 0 ° and less than 90 °. For example, in the embodiment of the present invention, the circle center is connected to the line O1O2And the included angle c and the included angle d of the corresponding straight connecting line both fall within the range of more than 0 degrees and less than 90 degrees.
As such, embodiments of the present invention can achieve the objective of relieving tensile forces by means of a rotating connection unit. Compared with the prior art, the embodiment of the invention can effectively reduce the possibility that the structures such as the connecting units corresponding to the island-shaped display units are damaged in the stretching process, thereby improving the reliability of the display panel and the display device comprising the display panel.
