Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
As described in the background, the stretchable display panel in the prior art is prone to have the metal wires break beyond the stretching limit of the metal wires during stretching. Fig. 1 is a schematic structural diagram of a stretchable display panel in the prior art, and referring to fig. 1, the stretchable display panel includes a flexible substrate 10, a pixel island 11 and a metal wire 12, the pixel island 11 and the metal wire 12 are located on the flexible substrate 10, and a plurality of pixel islands 11 are connected through the metal wire 12. In the stretching process of the stretchable display panel, especially in the intelligent wearable display device, the stretching proportion of the metal wires 12 is greatly limited, for example, the metal wires 12 are unevenly stressed at different positions due to different deformations of different parts of the flexible substrate 10, and the metal wires 12 at the positions with larger stress exceed the stretching limit of the metal wires and are broken, thereby causing the phenomenon of poor display.
In view of the above problems, embodiments of the present invention provide a stretchable carrier to restrict a stretchable portion of a display panel. Fig. 2 is a schematic top view of a stretchable carrier according to an embodiment of the present invention, and fig. 3 is a schematic cross-sectional view of the stretchable carrier shown in fig. 2 along a section line AA', it should be noted that the cross-sectional view shown in fig. 3 is only an exemplary structure. Referring to fig. 2 and 3, the stretchable carrier 100 provided by the embodiment of the present invention is divided into a stretchable zone 201 and a non-stretchable zone 202;
the stretchable carrier 100 comprises:
a stretchable substrate 110;
a restriction structure 120 on the stretchable substrate 110, the restriction structure 120 comprising a stretchable first restriction 101 and a non-stretchable second restriction 102, the first restriction and the second restriction being interconnected, the first restriction 101 being at least partially located in the stretchable region 201 and the second restriction 102 being located in the non-stretched region 202.
In particular, the restriction structure 120 is disposed on the stretchable substrate 110, which may be disposed on an inner portion of the stretchable substrate 110 or on a surface of the stretchable substrate 110. Among them, the material of the stretchable substrate 110 is a flexible stretchable material, such as Polydimethylsiloxane (PDMS) and Thermoplastic polyurethane elastomer (TPU), etc. Taking the material of the stretchable substrate 110 as PDMS for example, a layer of PDMS may be coated on the substrate, and then the limiting structure 120 is fabricated on the PDMS; it is also possible to first fabricate the confinement structure 120 and then coat PDMS on the confinement structure 120, which is not particularly limited in the embodiments of the invention. The restriction structure 120 includes a first restriction part 101 and a second restriction part 102, wherein the first restriction part 101 is in a stretchable state, and the second restriction part 102 is in a non-stretchable state, so that under the action of the non-stretchable second restriction part 102, the area where the second restriction part 102 is located is the non-stretching area 202, that is, when the stretchable carrier 100 is stretched, the non-stretching area 202 is not deformed due to the restriction effect of the second restriction part 102. Since the stretchable substrate 110 is a flexible stretchable material, other regions on the stretchable substrate 110 except the non-stretching region 202 where the second restriction portion 102 is located are stretchable regions 201, and the first restriction portion 101 is also stretchable, so that the stretchable carrier 100 can be stretched to a certain length within the stretching limit of the first restriction portion 101 when the stretchable carrier 100 is stretched.
In the embodiment of the present invention, the first restriction part 101 and the second restriction part 102 may be a unitary structure or a non-unitary structure, wherein the first restriction part 101 may be located only in the stretchable region 201 or may extend to the non-stretching region 202. Illustratively, when the first restriction part 101 and the second restriction part 102 are of a unitary structure, the first restriction part 101 is only located in the stretchable zone 201 to ensure the restriction effect of the second restriction part 102 on the non-stretchable zone 202 (as shown in fig. 3). Fig. 4 is a schematic cross-sectional view of another stretchable carrier according to an embodiment of the present invention, wherein fig. 4 specifically shows a structure in which the first restriction portion 102 extends to the non-stretching region 202. On the basis of the above technical solution, referring to fig. 4, when the first restriction part 101 and the second restriction part 102 are of a non-integral structure, in order to avoid a break point occurring at the boundary between the stretchable zone 201 and the non-stretchable zone 202 to affect the stretching effect of the stretchable carrier 100, the first restriction part 101 may be extended into the non-stretchable zone 202, so that the stretching effect of the stretchable carrier 100 can be improved. It should be noted that when the first limiting portion 101 extends to the non-stretching region 202, the first limiting portion 101 and the second limiting portion 102 may be connected by the adhesive, and the length of the second limiting portion 102 in the X direction is still equal to the length of the non-stretching region 202 (the non-stretching region 202 is defined by the non-stretching second limiting portion 102).
In the embodiment of the present invention, since the stretchable carrier 100 has the function of limiting the stretch ratio, the stretchable carrier 100 may be applied to the stretchable display panel to prevent the problem that the metal wires are broken by exceeding their own stretch limit during the stretching of the stretchable display panel. Fig. 5 is a schematic structural diagram of a stretchable display panel according to an embodiment of the present invention, and with reference to fig. 5 based on the above technical solutions, the stretchable display panel includes a stretchable display structure 300, where the stretchable display structure 300 includes a pixel island 301 and a stretchable connector 303 between adjacent pixel islands 301, where the pixel island 301 includes a plurality of sub-pixel units for implementing picture display; the stretchable connector 303 is disposed in a region between the two pixel islands 301 for stretching or bending, a metal wire 302 is disposed in the stretchable connector 303, the metal wire 302 may be at least one of a data signal line, a scan signal line or a power line, and the sub-pixel units in the pixel islands 301 are connected to the metal wire 302. In the embodiment of the present invention, the stretchable display structure 300 may be attached to the stretchable carrier 100 by glue, and the pixel islands 301 in the stretchable display structure 300 are disposed on the non-stretching regions 202 of the stretchable carrier 100, the stretchable connectors 303 are disposed corresponding to the stretchable regions 201 of the stretchable carrier 100, during stretching of the stretchable display structure 300 and the stretchable carrier 100, the maximum stretching length of the stretchable regions 201 of the stretchable carrier 100 is fixed due to the presence of the first restriction part 101 in the stretchable carrier 100, and the stretchable connectors 303 of the stretchable display structure 300 correspond to the stretchable regions 201 of the stretchable carrier 100, so that during stretching, the stretching length of the stretchable connectors 303 is kept in synchronization with the stretching length of the first restriction part 101, and the maximum stretching length thereof may be restricted by designing the structure and parameters of the first restriction part 101, thereby limiting the stretching ratio of the stretchable connecting body 303 and effectively preventing the metal wire 302 from breaking due to exceeding the stretching limit thereof. Meanwhile, since the second limiting portion 102 is of a non-stretchable structure, in the stretching process, the non-stretching region 202 limited by the second limiting portion 102 does not elastically deform, and therefore, the sub-pixel units in the pixel island 301 corresponding to the non-stretching region 202 do not tilt or become uneven, which is beneficial to improving the display effect.
According to the technical scheme provided by the embodiment of the invention, the stretchable carrier with the limiting structure is arranged on the stretchable substrate, so that the deformation of the stretchable carrier in the stretching process can be limited. Wherein the restriction structure comprises a stretchable first restriction located at least partially in the stretchable zone and a non-stretchable second restriction located in the non-stretchable zone. The stretchable carrier provided by the embodiment of the invention can be combined with the stretchable display structure to obtain the stretchable display panel, the stretching proportion of the stretchable display structure is limited by the stretchable first limiting part, and finally the stretching proportion of the stretchable display panel is limited, so that the metal wires are prevented from being broken and failing due to exceeding the stretching limit of the metal wires in the stretching process, the stretching reliability is improved, and the display effect of the stretchable display panel after stretching is greatly improved.
As an alternative to the embodiment of the present invention, the first limiting portions 101 and the second limiting portions 102 are alternately arranged. With reference to fig. 5, since the first limiting portion 101 is in the stretchable structure and the second limiting portion 102 is in the non-stretchable structure, the stretchable carrier 100 is uniformly stressed during stretching by arranging the first limiting portion 101 and the second limiting portion 102 alternately, so that the stretching effect of the stretchable carrier can be improved better. In the prior art, the stretchable display panel generally adopts an island-bridge connection manner, so that the first limiting portions 101 and the second limiting portions 102 arranged alternately can better match the structure of the stretchable display structure 300 in the stretchable display panel, and thus the stretchable connecting bodies 303 between the pixel islands 301 can be limited by the first limiting portions 101, and the metal wires 302 are prevented from breaking and failing due to exceeding the self-stretching limit.
In the embodiment of the present invention, the first limiting portion 101 and the second limiting portion 102 are made of the same material and are both nanofibers. The nanofibers have a certain rigidity and a good stability, so the second restriction portion 102 using the nanofibers can stably restrict the non-stretching region 202 from stretching deformation. In order to make the first restriction part 101, which is also made of nanofibers, stretchable, the shape of the first restriction part 101 may be designed to be bent (as shown in fig. 5), and thus a longer first restriction part 101 may be disposed within the same stretchable zone 201, thereby enabling the length of the first restriction part 101 to be increased, and when the stretchable zone 201 is stretched, the first restriction part 101 has an extension margin, thereby enabling the first restriction part 101 to be stretched.
In this embodiment, the restriction structure 120 is a net structure (as shown in fig. 2), the first restriction parts 101 and the second restriction parts 102 are alternately arranged, and the nanofibers are woven into the net structure to form the restriction structure 120, that is, the second restriction parts 102 arranged along the X direction intersect with the second restriction parts 102 arranged along the Y direction, and the area formed by the intersecting second restriction parts 102 is the non-stretching area 202. The net-shaped restriction structure 120 can ensure that the stretchable carrier 100 is stressed more uniformly at each position during the stretching process, and can better restrict the stretchable region 201 and the non-stretchable region 202.
Of course, in other embodiments, the shape of the first limiting portion 101 may be any other shape capable of increasing its length. For example, the first restriction part 101 may also be in a curled shape or a spiral shape, the spiral-shaped first restriction part 101 can be stretched like a spring, and designing the first restriction part 101 in a curled shape or a spiral shape can reduce the arrangement length of the first restriction part 101 in the X direction, so that the stretch ratio of the stretchable region 201 can be increased.
In another alternative embodiment of the present invention, the first limiting portion 101 is made of an elastic material, and the second limiting portion 102 is made of a rigid material.
The first limiting portion 101 and the second limiting portion 102 are adhered by glue. The embodiment of the present invention is described by taking the first restriction part 101 located in the stretchable zone 201 and the second restriction part 102 located in the non-stretchable zone 202 as an example. During the stretching of the stretchable carrier 100, the first restriction portion 101 restricts the stretching ratio of the stretchable zone 201 according to its own elastic modulus; since the second restriction part 102 is made of a rigid material, the second restriction part 102 is not deformed, that is, the non-stretching region 202 restricted by the second restriction part 102 is not deformed.
As another alternative to the embodiment of the present invention, fig. 6 is a schematic cross-sectional structure diagram of another stretchable carrier provided in the embodiment of the present invention, and on the basis of the above technical solutions, referring to fig. 6, the first restriction part 101 and the second restriction part 102 are located at different layers, and the first restriction part 101 is located at the stretchable zone 201 and the non-stretchable zone 202. Compared with the stretchable carrier shown in fig. 4, the first restriction part 101 of the stretchable carrier shown in fig. 6 is further located in the non-stretching region 202, and the second restriction part 102 is disposed at a different layer from the first restriction part 101, wherein the first restriction part 101 and the second restriction part 102 may be attached to each other or disposed independently of each other, the second restriction part 102 may be disposed on a film layer on the upper surface of the first restriction part 101 or on the lower surface of the first restriction part 102, and the region where the second restriction part 102 is disposed is the non-stretching region 202.
It should be noted that the stretchable carrier 100 shown in fig. 6 is configured such that the non-stretching region 202 defined by the stretchable first restriction portion 101 is restricted by the non-stretchable second restriction portion 202, and therefore, in order to ensure the restriction effect of the second restriction portion 102 on the non-stretching region 202, it is required to ensure that the elastic modulus of the second restriction portion 102 is much larger than that of the first restriction portion 101, that is, the rigidity of the second restriction portion 102 is larger than that of the first restriction portion 101.
Optionally, an embodiment of the present invention further provides a stretchable display panel, where the stretchable display panel includes a stretchable display structure and a stretchable carrier provided in any embodiment of the present invention, and the stretchable display structure and the stretchable carrier are attached to each other. Fig. 7 is a top view of a stretchable display panel according to an embodiment of the present invention, and fig. 8 is a schematic cross-sectional view of the stretchable display panel shown in fig. 7 along a section line BB'. On the basis of the above technical solutions, referring to fig. 7 and 8, the stretchable display panel includes a stretchable display structure, the stretchable display structure includes a pixel region 310 and a non-pixel region 320, the pixel region 310 corresponds to the non-stretching region 202, and the non-pixel region 320 corresponds to the stretchable region 201.
Specifically, the pixel region 310 includes a pixel island 301, and the pixel island 301 includes a plurality of sub-pixel units for implementing image display; the stretchable connector 303 is disposed in a region between the two pixel islands 301 for stretching or bending, a metal wire 302 is disposed in the stretchable connector 303, the metal wire 302 may be at least one of a data signal line, a scan signal line or a power line, and the sub-pixel units in the pixel islands 301 are connected to the metal wire 302. The stretchable carrier 100 includes a restriction structure 120, and the first restriction portion 101 and the second restriction portion 102 in the restriction structure 120 correspond to the non-pixel region 320 and the pixel region 310 of the stretchable display panel, respectively, wherein the restriction structure 120 is a mesh structure. Referring to fig. 2, taking the material of the confinement structure 120 as an example of a nanofiber, the first and second confinement portions 101 and 102 are alternately arranged, wherein, along the X direction, the distance between adjacent second confinement portions 102 is equal to the length of the pixel island 301. The restriction structure 120 is formed by weaving the nanofibers into a net structure, that is, the second restriction parts 102 arranged along the X direction intersect with the second restriction parts 102 arranged along the Y direction, the area formed by the intersecting second restriction parts 102 is the non-stretching area 202, and the non-stretching area 202 corresponds to the pixel area 310 of the stretchable display panel. The stretchable carrier 100 is formed by coating a stretchable base material on the restriction structures 120 woven into a mesh shape, and the stretchable base 110 is cured to wrap the restriction structures 120, and the thickness of the stretchable carrier 100 in the Z direction may be 150 μm, or other thicknesses may be set according to actual needs. The stretchable carrier 100 is attached to the stretchable display structure (e.g., the attachment may be performed by liquid glue or OCA glue), and the pixel region 310 corresponds to the non-stretching region 202 and the non-pixel region 320 corresponds to the stretchable region 201. During the stretching process, the stretching length of the first limiting part 101 is smaller than that of the metal wire 302, so the stretching ratio of the metal wire 302 can be limited by the first limiting part 101, so that the metal wire 302 does not exceed its own stretching limit during the stretching process. In addition, the second restriction portion 102 is not stretchable, and the length of the second restriction portion is equal to the length of the pixel island 310 along the stretching direction, so that the non-stretching region 202 of the stretchable carrier 100 is not elastically deformed during stretching, and therefore, the pixel island 301 is not inclined or uneven. According to the technical scheme provided by the embodiment of the invention, the stretching length of the first limiting part 101 is smaller than that of the metal wire 302 in the stretching direction, and the length of the second limiting part 102 is equal to that of the pixel island 310, so that the total stretching length of the stretchable display panel after stretching is larger than that of the stretchable carrier 100, all structures on the stretchable display panel are limited, the stretching ratio of the metal wire 302 and the stretching shape of the pixel island 301 are specified (the pixel island 301 does not elastically deform due to the limiting action of the second limiting part 102), the phenomenon that the metal wire 302 breaks due to exceeding the stretching limit of the pixel island 301 is further prevented, and the stretching reliability and the display effect of the stretchable display panel after stretching are improved.
Of course, in other embodiments, the stretchable display panel may also be limited by using the stretchable carrier 100 in which the first limiting portion 101 is made of an elastic material and the second limiting portion 102 is made of a rigid material, so long as it is ensured that the stretched length of the first limiting portion 101 after being elastically deformed is smaller than the stretched length of the metal wire 302, and the length of the second limiting portion 102 is equal to the length of the pixel island 301, so that the metal wire 302 can be prevented from being broken due to exceeding its own stretching limit. The specific working principle is the same as the stretching principle of the stretchable display panel, and is not described herein again.
It is to be noted that the foregoing is only illustrative of the preferred embodiments of the present invention and the technical principles employed. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention. Therefore, although the present invention has been described in greater detail by the above embodiments, the present invention is not limited to the above embodiments, and may include other equivalent embodiments without departing from the spirit of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
