Referring to fig. 1, fig. 1 is a schematic view of a first structure of a display device provided in the present application. As shown in fig. 1, the display device includes: a support substrate 11, the support substrate 11 including a first support part 111, a second support part 112, and a curved support part 113 disposed between the first support part 111 and the second support part 112; the first adhesive layer 12, the first adhesive layer 12 is disposed on the first supporting portion 111 and the second supporting portion 112; a flexible substrate 13, the flexible substrate 13 including a first portion 131, a second portion 132, and a flexible portion 133 disposed between the first portion 131 and the second portion 132; the first portion 131 and the second portion 132 are disposed on the first adhesive layer 12, and the flexible portion 133 is disposed corresponding to the curved support portion 113.
The material of the support substrate 11 is PET plastic (Polyethylene terephthalate) or stainless steel. The support substrate 11 has high rigidity, and can improve the stiffness of the flexible substrate 13 and prevent the flexible substrate 13 from being too soft.
The material of the first Adhesive layer 12 may be OCA (optical Clear Adhesive) or other Adhesive material with good adhesion and light transmission.
The material of the flexible substrate 13 is Polyimide (Polyimide Film). The polyimide material has the advantages of being wide in temperature, resistant to chemical corrosion, high in strength and the like, so that the flexible substrate 13 has good flexibility.
The display device further includes a functional layer 14, a polarizer 15, an adhesive layer 16, and a cover plate 17 sequentially disposed on the flexible substrate 13. The functional layer 14 may include an array layer and a pixel light emitting layer (not shown), which are well known to those skilled in the art and will not be described herein.
It should be noted that the functional layer 14 may be disposed only on the first portion 131, and the display device displays the area on the first portion 131; the functional layer 14 may be disposed only on the first portion 131 and the second portion 132, and the display device may display the regions on the first portion 131 and the second portion 132; the functional layer 14 may be disposed on the entire flexible substrate 13, and the present application is not particularly limited thereto.
In the embodiment of the present application, the functional layer 14 is only disposed on the first portion 131, and the flexible portion 133 is disposed with a related signal trace (not labeled) thereon, so as to implement signal transmission between the first portion 131 and the second portion 132.
It should be noted that the film layer structure of the display device provided by the present application is not limited to the above embodiments. The contents of the above embodiments are merely to explain the overall structure of the display device provided in the present application in more detail, and are not to be construed as limiting the present application.
This application embodiment is through getting rid of the part that first glue film 12 is located between curved surface supporting part 113 and the flexible portion 133, for curved surface supporting part 113 and flexible portion 133 provide the accommodation space of buckling deformation, reduced the fold that the deformation of curved surface supporting part 113 produced to the extrusion of flexible portion 133, and then reduced the stress that the signal that is located on the flexible portion 133 was walked the line and is received, effectively avoided the signal to walk the line and take place the fracture. Meanwhile, compared with the prior art, the embodiment of the application maintains the curved supporting portion 113 corresponding to the flexible portion 133 in the supporting substrate 11 on the basis of removing the portion of the first adhesive layer 12 between the curved supporting portion 113 and the flexible portion 133, thereby improving the protection of the flexible substrate 13.
In the embodiment of the present application, since the first adhesive layer 12 is not disposed between the curved supporting portion 113 and the flexible portion 133, a cavity is formed between the curved supporting portion 113 and the flexible portion 133 at the beginning of bending, and the lengths of the upper surface and the lower surface of the cavity are the same, that is, the lengths of the curved supporting portion 113 and the flexible portion 133 are the same. In the bending process, the curved surface supporting part 113 and the flexible part 133 have a mutual constraint effect, so that damage to a product caused by process errors such as alignment deviation can be avoided.
Further, because the first adhesive layer 12 is not arranged between the curved surface supporting portion 113 and the flexible portion 133, the curved surface supporting portion 113 cannot be pressed by stress generated by creeping of the first adhesive layer 12, therefore, the radian of the curved surface supporting portion 113 is greater than 180 degrees, and the radian of the curved surface supporting portion 113 is greater than that of the flexible portion 133, so that the curved surface supporting portion 113 and the flexible portion 133 are at least partially attached to each other, and then a mutual supporting structure is formed between the curved surface supporting portion 113 and the flexible portion 133, and a certain protection supporting effect is achieved.
Specifically, the size of the fitting area between the curved supporting portion 113 and the flexible portion 133 depends on the thicknesses of the first adhesive layer 12 and the supporting substrate 11. In the embodiment of the present application, the thickness of the supporting substrate 11 is between 30 microns and 80 microns; the thickness of the first adhesive layer 12 is between 50 micrometers and 100 micrometers, and can be specifically designed according to the thickness specification of the display device.
In the embodiment of the present application, a side of the flexible substrate 13 away from the support substrate 11 is further provided with a fourth glue layer 18. The fourth glue layer 18 covers at least the flexible portion 133.
The fourth adhesive layer 18 is made of an ultraviolet curing adhesive. After the ultraviolet curing adhesive is irradiated by ultraviolet light, the surface of the ultraviolet curing adhesive loses viscosity, so that the fourth adhesive layer 18 is arranged on the flexible portion 133, the stiffness of the flexible portion 133 can be properly increased, the problem that the flexible portion 133 is easy to deform when the display device is subjected to external force such as extrusion and the like is avoided, and signal routing on the flexible portion 133 is better protected.
In the embodiment of the present application, the second portion 132 may or may not display a picture, and may be designed according to the requirement of the display device in the market, which is not specifically limited in the present application.
For example, in some embodiments, with reference to fig. 1, the second portion 132 is a bonding region of the display device, and the source chip-on-chip 20 is bonded to the second portion 132; the printed circuit board 30 is connected to the flexible substrate 13 through the source chip on film 20. The source chip on film 20 and the printed circuit board 30 are bent to the back side of the flexible substrate 13 by the flexible portion 133, thereby implementing a narrow bezel design of the display device.
In other embodiments, please refer to fig. 2, wherein fig. 2 is a second structural diagram of the display device provided in the present application. As shown in fig. 2, the two display screens are connected and oppositely disposed through the bending area, and the two display screens respectively display corresponding pictures outwards, that is, the second portion 132 is provided with a film layer structure the same as that of the first portion 131, and also performs picture display as the display area, so as to make up for the disadvantage that the traditional single-sided display device can only display pictures on one side.
Referring to fig. 3, fig. 3 is a schematic diagram of a third structure of the display device provided in the present application. The difference from the display device shown in fig. 1 is that, in the display device provided in the embodiment of the present application, at the boundary between the first supporting portion 111 and the curved supporting portion 113, the end of the first glue layer 12 is in a wedge shape to fill the gap between the curved supporting portion 113 and the flexible portion 133. Similarly, at the boundary between the second supporting portion 112 and the curved supporting portion 113, the other end of the first adhesive layer 12 is also wedge-shaped to fill the gap between the curved supporting portion 113 and the flexible portion 133.
Correspondingly, referring to fig. 4, fig. 4 is a first structural diagram of the display device shown in fig. 3 before being bent. As shown in fig. 4, an included angle between the first side surface 12a of the first glue layer 12 on the first supporting portion 111 and a side surface of the first supporting portion 111 facing the flexible substrate 13 is an obtuse angle; the second side surface 12b of the first adhesive layer 12 on the second supporting portion 112 forms an obtuse angle with the surface of the second supporting portion 112 facing the flexible substrate 13.
Specifically, in the bending process of the display device, because the first side surface 12a and the second side surface 12b are obliquely arranged, when the curved surface supporting portion 113 is bent upwards, the first adhesive layer 12 has certain fluidity, and a certain space is reserved between the first side surface 12a and the flexible substrate 13, so that the first adhesive layer 12 creeps towards the space when being extruded, and the bending stress on the curved surface supporting portion 113 and the flexible portion 133 is reduced. Meanwhile, the first side surface 12a is obliquely arranged, which is equivalent to the thickness of the first glue layer 12 at the junction of the first supporting part 111 and the curved supporting part 113 is reduced; the second side surface 12b is obliquely arranged, which is equivalent to the thickness reduction of the first glue layer 12 at the junction of the second supporting part 112 and the curved supporting part 113; thus, the compression of the flexible portion 133 by the folds produced by the peristaltic motion of the first glue layer 12 is avoided. In addition, the first adhesive layer 12 fills the gap between the curved supporting portion 113 and the flexible portion 133, so that the adhesive layer bonding area between the curved supporting portion 113 and the flexible portion 133 is larger, the bonding force between the supporting substrate 11 and the flexible substrate 13 is enhanced, and the supporting substrate 11 is prevented from falling off.
Wherein, the fit degree between the curved supporting portion 113 and the flexible portion 133 depends on the thickness of the first glue layer 12. The thinner the thickness of the first adhesive layer 12 is, the larger the attachment area between the curved surface supporting portion 113 and the flexible portion 133 is. Therefore, specific values of the included angle between the first side surface 12a and the side surface of the first supporting portion 111 facing the flexible substrate 13 and the included angle between the second side surface 12b and the side surface of the second supporting portion 112 facing the flexible substrate 13 may be selected according to the thickness of the first glue layer 12, and the application is not limited thereto.
In some embodiments, please refer to fig. 5, fig. 5 is a second structural diagram of the display device shown in fig. 3 before being bent. The difference from the display device before bending as shown in fig. 4 is that the first adhesive layer 12 may cover a part of the curved surface supporting portion 113.
Since the first side surface 12a and the second side surface 12b are obliquely arranged, the thickness of the first adhesive layer 12 at the boundary of the first supporting portion 111 and the curved supporting portion 113 and at the boundary of the second supporting portion 112 and the curved supporting portion 113 is reduced. Therefore, the first adhesive layer 12 covers part of the curved supporting portion 113, so as to ensure that a sufficient accommodating space is left between the curved supporting portion 113 and the flexible portion 133, and the curved supporting portion 113 is not squeezed. Meanwhile, after the display device is bent, the first adhesive layer 12 may better fill the gap between the curved support portion 113 and the flexible portion 133 by pressing and creeping.
Referring to fig. 6, fig. 6 is a fourth structural schematic diagram of the display device provided in the present application. The difference from the display device shown in fig. 1 is that, in the display device provided in the embodiment of the present application, a groove 130 is provided on a surface of one side of the curved supporting portion 113 facing the flexible substrate 13. In order to support the flexible substrate 13, the support substrate 11 has a certain rigidity, and the curved support portion 113 is provided with the groove 130 on the surface of the side facing the flexible substrate 13, which is equivalent to thinning the curved support portion 113, so that the flexibility of the curved support portion 113 can be improved, and the integrity of the support substrate 11 is maintained.
Further, please refer to fig. 7, wherein fig. 7 is a fifth structural diagram of the display device provided in the present application. The difference from the display device shown in fig. 6 is that the groove 130 is filled with the second glue layer 22. Specifically, a coating process or a sheet material attaching process may be used to dispose the second adhesive layer 22 in the first groove 130.
The thickness of the second adhesive layer 22 may be greater than or equal to the depth of the groove 130, which is not limited in this application.
The material of the second adhesive layer can be OCA or other adhesive materials with good adhesive property and light transmission property.
In this embodiment, since the groove 130 is disposed on the surface of the curved surface supporting portion 113 facing the flexible substrate 13, the creeping of the second adhesive layer 22 in the groove 130 will not extrude the curved surface supporting portion 113, and the curved surface supporting portion 113 and the flexible portion 133 are attached to each other through the second adhesive layer 22, so that the bonding force between the curved surface supporting portion 113 and the flexible portion 133 is increased, and the supporting substrate 11 is prevented from falling off. In addition, the second adhesive layer 22 can provide more deformation, so that the bending stress is reduced, and the signal traces on the flexible substrate 13 are prevented from being broken.
Referring to fig. 8, fig. 8 is a sixth structural schematic diagram of the display device provided in the present application. The difference from the display device shown in fig. 1 is that, in the display device provided in the embodiment of the present application, the surface of the side of the curved supporting portion 113 facing the flexible substrate 13 is provided with the third glue layer 32. The thickness of the third adhesive layer 32 is less than that of the first adhesive layer 12.
Specifically, the thickness of the first adhesive layer 12 may be increased accordingly, so that before the display device is bent, a sufficient space is provided between the curved supporting portion 113 and the flexible portion 133 to accommodate the bending deformation of the curved supporting portion 113 and the wrinkle generated by bending the third adhesive layer 32. The curved supporting portion 113 and the flexible portion 133 are attached to each other through the second adhesive layer 22, so that the bonding force between the curved supporting portion 113 and the flexible portion 133 is increased, and the support substrate 11 is prevented from falling off. Meanwhile, the second adhesive layer 22 can provide more deformation, so that the bending stress is reduced, and further, the signal traces on the flexible substrate 13 are prevented from being broken.
