Fig. 1 is a schematic partial structure diagram of a stretchable display panel according to an embodiment of the present invention. The stretchable display panel of the present embodiment may be an OLED display panel. The stretchable display panel 100 of the embodiment of the present invention includes a display area 100a and a non-display area 100b located at a peripheral side of the display area 100 a. The non-display area 100b is generally provided with a trace for binding a Flexible Printed Circuit Board (FPC)/Integrated Circuit (IC).
It is understood that, for a stretchable display panel, generally, the display area 100a includes a plurality of display devices arranged in an array and signal lines connected to the respective display devices. The display area 100a is provided with a stretchable area and a configuration area, the stretch performance of the configuration area is relatively small, the display device is located in the configuration area, and the signal line is located in the stretchable area, so that the display performance of the display device can be ensured, the display area 100a has the stretchable performance, and the specific structure of the display area can refer to the existing island bridge structure. The tensile modulus is substantially uniform throughout the display area 100a due to the distribution of the array of display devices.
In this embodiment, the non-display area 100b includes a tensile modulus adjusting structure, and the tensile modulus of the non-display area 100b can be adjusted by the tensile modulus adjusting structure, so that the tensile modulus of the non-display area 100b is consistent with the tensile modulus of the display area 100a, which is beneficial to maintaining the same tensile property at each position of the whole display panel.
There are many implementations of the tensile modulus adjustment structure, and in some alternative embodiments, as shown in fig. 1, the tensile modulus adjustment structure includes a plurality of hard island structures 12 with gaps between adjacent hard island structures 12. It is understood that the non-display region 11b further includes a plurality of stretchable conductive wires 11, and at least a portion of the stretchable conductive wires 11 is located on the rigid island structure 12, but it is understood that the stretchable conductive wires may not be in contact with the rigid conductive structure 12, and the rigid island structure 12 is used to adjust the tensile modulus of the non-display region 100b so that the tensile modulus of the non-display region 100b is consistent with the tensile modulus of the display region 100 a.
In this embodiment, a plurality of rigid island structures 12 are disposed in the non-display area 100b, and in at least a part of the stretchable conductive wires 11 in the non-display area 100b, the same stretchable conductive wire 11 is connected to the rigid island structures 12, so that the tensile modulus of the non-display area 100b can be adjusted to be consistent with that of the display area 100a, which is beneficial for maintaining the same stretching characteristics at various positions of the entire display panel.
It will be appreciated that the tensile conductor 11 is typically provided on a flexible substrate, and the rigid island structure 12 described above may be implemented in a number of ways.
In some alternative embodiments, referring to fig. 2 and fig. 3, fig. 2 is a partial schematic top view of a hard island structure provided in an embodiment of the present invention, and fig. 3 is a partial schematic side view of a hard island structure provided in an embodiment of the present invention with a stretchable wire connected thereto. A base 14 and a flexible substrate 15 are provided in a stacked manner in the non-display region 100 b. The flexible substrate 15 includes a plurality of block structures 151 and a plurality of linear structures 152, and the linear structures 152 may be linear structures or curved structures, and the curved structures are preferred because the curved structures have better stretching effect. At least a portion of the line structures 152 are connected to the bulk structures 151, it being understood that the flexible substrate 15 may be subjected to a process such as laser etching to form a plurality of bulk structures 151 and a plurality of line structures 152, and the invention is not limited to the specific forming process thereof. The bulk structures 151 have substantially no tensile properties, whereas the linear structures 152 have better tensile properties, the bulk structures 151 form the above-described hard island structures. When the stretchable conductive wires 11 are formed on the side of the flexible substrate 15 facing away from the base 14, a portion of the same stretchable conductive wire 11 of the partially stretchable conductive wires 11 may be formed on the linear structure 152 and another portion may be formed on the block structure 151. It is also possible that all of the tensile wires 11 are partially formed on the linear structure 152 and partially formed on the block structure 151. The stretchable conductive wires 11 formed on the linear structures 152 have a stretching property, while the stretchable conductive wires 11 formed on the block structures 151 have substantially no stretching property. In these embodiments, the tensile modulus of the non-display region 100b is adjusted by implementing a hard island structure by disposing a plurality of bulk structures 151 on the flexible substrate 15.
In other alternative embodiments, referring to fig. 4, fig. 4 is a partial side view of another rigid island structure with stretchable conductive wires connected thereto according to an embodiment of the present invention. Different from the above embodiment, a plurality of metal sheets 16 are disposed between the base 14 and the flexible substrate 15, and the plurality of metal sheets 16 are disposed on the base 14, and a gap is disposed between adjacent metal sheets 16, the metal sheets 16 may be, for example, copper sheets or aluminum sheets, the flexible substrate 15 completely covers the metal sheets 16, and the flexible substrate 15 and the metal sheets 16 on each metal sheet 16 form the above-mentioned hard island structure because the flexible substrate 15 disposed on the metal sheet 16 has a small stretching performance. Likewise, when the stretchable conductive wires 11 are formed on the side of the flexible substrate 15 facing away from the base 14, a portion of the same stretchable conductive wire 11 of the partially stretchable conductive wires 11 may be formed on the flexible substrate 15 above the metal sheet 16, and another portion may be formed on the flexible substrate 15 of the other portion. It is also possible that all the stretchable conductive wires 11 are formed on the flexible substrate 15 with one portion formed over the metal sheet 16 and the other portion formed on the flexible substrate 15 with the other portion. The stretchable conductive wires 11 formed on the flexible substrate 15 over the metal sheet 16 have substantially no stretchability, while the stretchable conductive wires 11 disposed on the flexible substrate 15 at other portions have a stretchability. In these embodiments, the tensile modulus of the non-display region is adjusted by implementing a rigid island structure by disposing a plurality of metal sheets 16 between the flexible substrate 15 and the base 14.
It should be noted that, in order to ensure the stretchable characteristic of the stretchable conductive lines 11 in the non-display area 100b, the portions of the stretchable conductive lines 11 not connected to the rigid island structures 12 are in a bent structure. The shape of the curved structure may be an S-curve shape or a sine curve shape, and may be a curved shape in which a plurality of S-curves and/or sine curves are connected. Further, the portion of the flexible substrate 15 formed with the stretchable wire 11 without the rigid island structure 12 may have the same curved shape as the stretchable wire 11, that is, the flexible substrate 15 may include a plurality of curved structures with a gap therebetween, and the curved stretchable wire 11 is formed on the curved structures to enhance the stretching performance of the portion of the stretchable wire 11.
It is understood that the hard island structure 12 may be formed only by forming some regions with smaller tensile properties in the non-display region 11b, and there are other implementations of the hard island structure 12, which are not described herein again.
In some alternative embodiments, the portion of the stretchable wire 11 located on the rigid island structure 12 is straight. Arranging the stretchable wires 11 on the hard island structures 12 in a straight line may reduce the on-resistance and RC delay of the portion of the stretchable wires 11.
The number and size of the hard island structures 12 is not a limitation of the present invention. The size and number of the hard island structures 12 can be designed and calculated by software simulation before the display panel is manufactured. It is understood that the size of each hard island structure 12 in the non-display area 100b may be the same or different.
From the viewpoint of manufacturing process, the hard island structure 12 may be configured in a rectangular shape or a square shape, and of course, in other embodiments, the hard island structure 12 may also be in other shapes. The specific shape of the hard island structure 12 may be set according to actual needs.
As shown in fig. 1, in some alternative embodiments, the non-display area 100b may further include a plurality of first insulation bending lines 13, and at least a portion of the first insulation bending lines 13 are connected to the hard island structure 12. The first insulating bend line 13 does not affect the conductive performance of the non-display area 100b, and the tensile modulus of the non-display area 100b may be further adjusted to be consistent with that of the display area 100a under the combined action of the hard island structure 12 and the non-display area 100 b.
In order to make the tensile modulus of the first direction (Y direction) of the non-display area 100b coincide with that of the second direction (X direction), the arrangement direction of the first insulating bend lines 13 should coincide with the direction in which the number of stretchable wires 11 of the non-display area is small. It is understood that the stretchable conductive wires 11 in the non-display area 100b need to be connected to the signal lines in the display area 100a to control the display devices in the display area to emit light, and the stretchable conductive wires 11 are usually connected to the signal lines along the second direction (X direction) and then bent along the first direction (Y direction) to reduce the size of the frame region. Since the stretchable conductive wires 11 extend generally short in the second direction, causing the tensile modulus in the second direction to be inconsistent with that in the first direction, the first insulating bend lines 13 may be arranged in the second direction (X direction) in order to make the tensile modulus uniform throughout the non-display region 100 b. It will be appreciated that the first direction is perpendicular to the second direction. Of course, the first insulation bending line 13 may be provided in the first direction as needed.
There may be a plurality of arrangements of the first insulating bending lines 13, one of the arrangements may be that the flexible substrate 15 of the above embodiment may be further patterned to form a plurality of curved structures extending along the first direction and a plurality of curved structures extending along the second direction, a part of the flexible substrate 15 of the curved structures is provided with the stretchable conductive lines 11, and the other part of the flexible substrate 15 of the curved structures is the first insulating bending lines 13, which may adjust the tensile modulus of the non-display area 100b together with the hard island structures 12. It will be appreciated that in this arrangement, the insulating bend lines 13 are patterned from the flexible substrate 14, and the manufacturing process is relatively simple.
In another arrangement, some of the first insulation bending lines 13 may be further provided at a different layer from the flexible substrate 15 to further adjust the tensile modulus of the non-display area 100 b. Specifically, some insulating layer structures may be added to the non-display area 100b, and then patterned to form the first insulating bending lines 13.
The materials of the flexible substrate 15 and the insulating bending line 13 mentioned in the above embodiments may be both polyimide.
In other alternative embodiments, please refer to fig. 5, and fig. 5 is a schematic partial structure diagram of another stretchable display panel according to an embodiment of the present invention. The stretchable display panel 100 of the embodiment of the present invention includes a display area 100a and a non-display area 100b located at a peripheral side of the display area 100 a.
In the embodiment of the present invention, the tensile modulus adjustment structure includes the plurality of second insulation bending lines 17, and the second insulation bending lines 17 may adjust the tensile modulus of the non-display area 100b to conform the tensile modulus of the non-display area 100b to the tensile modulus of the display area 100 a.
In the present embodiment, the plurality of second insulation bending lines 17 are provided in the non-display area 100b, and the tensile modulus of the non-display area 100b may be adjusted so that the tensile modulus of the non-display area 100b is consistent with that of the display area 100a, which is beneficial to maintaining the same tensile characteristics at various positions of the entire display panel, and the structure is simple in manufacturing process.
In this embodiment, the direction in which the second insulating bend line 17 is provided is not limited, and may be along the first direction and/or the second direction, or may be along another direction.
In an alternative implementation, the non-display area 100b may be provided with the base 14, the flexible substrate 15, and the stretchable conductive wires 11 sequentially stacked, the flexible substrate 15 being a mesh structure connected along bending lines crossing the first and second directions, and the stretchable conductive wires 11 being disposed on the flexible substrate 15, so that portions of the flexible substrate 15 not provided with the stretchable conductive wires 11 may serve as the second insulating bending lines 17 to adjust the tensile modulus of the non-display area 100 b.
It is understood that the stretchable conductive wires 11 in the non-display area 100b need to be connected to the signal lines of the display area 100a to control the display devices in the display area 100a to emit light, and the stretchable conductive wires 11 are usually connected to the signal lines along the second direction (X direction) and then bent along the first direction (Y direction) to reduce the size of the frame region. Since the stretchable conductive wires 11 extend generally short in the second direction, resulting in a tensile modulus in the second direction different from that in the first direction, and the second insulation bent lines 17 are arranged in the second direction (X direction), the tensile modulus in the second direction may be increased to make the tensile modulus of the entire non-display area 100b consistent with that of the display area 100 a.
In another alternative implementation, the stretchable conductive wires 11 may be formed on the flexible substrate 15, and the second insulating bending lines 17 may be formed in a layer different from the flexible substrate 15, and adjustment of the tensile modulus of the non-display region may also be implemented.
The invention further provides an embodiment of a display device, which comprises the stretchable display panel of any embodiment, and the display device can be any product or component with a display function, such as a mobile phone, a tablet computer, a television, a notebook computer, a digital photo frame, a navigator, electronic paper and the like. But also stretchable displays, artificial display skin, convex or 3D shaped displays, etc.
Since the display device according to the embodiment of the present invention includes the stretchable display panel according to any one of the embodiments, the beneficial effects of the stretchable display panel according to the embodiments are not repeated herein.
While the invention has been described with reference to specific embodiments, the invention is not limited thereto, and various equivalent modifications and substitutions can be easily made by those skilled in the art within the technical scope of the invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
