Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all 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 application.
In order to solve the problem that when an existing flexible display panel is bent, different material layers of a non-display area are easily peeled off, and a packaging effect of the non-display area is affected, embodiments of the present application provide a flexible display panel and a display device, which will be described below with reference to the accompanying drawings.
For example, please refer to fig. 1, and fig. 1 is a schematic structural diagram of a display device according to an embodiment of the present disclosure. The embodiment of the application provides a display device 1, and the display device 1 may include a flexible display panel 10 and a driving chip 20, where the driving chip 20 is electrically connected to the flexible display panel 10. The driving chip 20 is used for driving the display or the scrolling operation of the flexible display panel 10, and may be understood as a control center of the display device 1. The display device 1 can be bent, folded or otherwise deformed to exhibit different display effects, thereby satisfying the viewing habits of different users on the display device 1. For example, the display device 1 may be a mobile electronic device such as a mobile phone and a tablet, and the display device 1 may also be a device having a display function such as a computer device, a television, and a vehicle-mounted computer.
The display device 1 may include an OLED (Organic Light-Emitting semiconductor) device, or the Light-Emitting form of the components in the display device 1 is an OLED Light-Emitting form, which belongs to a current-type Organic Light-Emitting device and is a phenomenon of Light emission caused by injection and recombination of carriers, and the Light-Emitting intensity is proportional to the injected current. Under the action of an electric field, holes generated by an anode and electrons generated by a cathode move, are respectively injected into a hole transport layer and an electron transport layer, and migrate to a light emitting layer. When the two meet at the light emitting layer, energy excitons are generated, thereby exciting the light emitting molecules to finally generate visible light. Compared to the Crystal layer of an LED (Light-Emitting Diode) or an LCD (Liquid Crystal Display), the organic plastic layer of an OLED is thinner, lighter, and more flexible. In addition, the OLED can be produced on different flexible substrate materials such as plastics, resins and the like, and the soft screen or the flexible screen can be realized by evaporating or coating an organic layer on a plastic substrate. OLEDs have many advantages such as self-luminescence, low driving voltage, high luminous efficiency, short response time, high definition and contrast, wide viewing angle, and wide temperature range, and are considered to be the most promising display.
Wherein the flexible display panel 10 is a main device in the display device 1, the bending or folding of the flexible display panel 10 is usually considered to be implemented in the display device 1. In order to explain that the flexible display panel 10 according to the embodiment of the present application can solve the problem that peeling is easily generated between different material layers when the flexible display panel 10 is bent, a composition structure of the flexible display panel 10 will be described below.
For example, please refer to fig. 2 in combination with fig. 1, and fig. 2 is a schematic structural diagram of a flexible display panel in the display device shown in fig. 1. The embodiment of the present application also provides a flexible display panel 10, and the flexible display panel 10 may also be referred to as a flexible screen. From the viewpoint of the constituent layer structure of the flexible display panel 10, the flexible display panel 10 may generally include a light emitting layer and a driving layer that drives the light emitting layer to emit light. The flexible display panel 10 may include a display area 11 and a non-display area 12, as viewed from a display surface facing the flexible display panel 10, the non-display area 12 being disposed around the display area 11. The display area 11 is also an area where the flexible display panel 10 displays a screen. The non-display region 12 may include an encapsulation region, a cathode overlapping region, and a binding region, and the encapsulation region may be disposed between the cathode overlapping region and the binding region. The cathode overlapping area is arranged close to the display area 11, the cathode overlapping area is used for overlapping the cathode and the VSS signal lines, and the binding area is used for binding all the signal lines of the display area 11 with the control chip or the integrated circuit. The non-display area 12, which may also be referred to as a routing area, is a scanning line or a signal line exit in the display area 11. The non-display area 12 is not normally displayed, and thus the flexible display panel 10 may be encapsulated by using this portion. Note that, in manufacturing the flexible display panel 10, the non-display region 12 structure is generally manufactured following the manufacturing of the display region 11 structure. The display region 11 may have a stacked structure, and thus the non-display region 12 may have a stacked structure. However, when the flexible display panel 10 is bent, the adhesion between different material layers is not strong due to different materials of different layer structures, and stress concentration is easily caused between different material layers, so that peeling easily occurs between different material layers of the non-display area 12, and the packaging effect of the non-display area 12 is affected.
In order to solve the above problem, the embodiment of the present application improves the composition structure of the non-display area 12. For example, please refer to fig. 3 and 4 in combination with fig. 1 and 2, in which fig. 3 is a first cross-sectional view of a portion of the structure in the non-display area of the flexible display panel shown in fig. 2, and fig. 4 is a structural view of another angle of the portion of the structure in the non-display area shown in fig. 3. At least three insulating layers 120 may be disposed in the non-display region 12, and a metal layer 122 may be disposed between two adjacent insulating layers 120. At least one metal layer 122 is provided with at least one through hole 124, and one insulating layer 120 of the insulating layers 120 on two sides of the metal layer 122 provided with the through hole 124 penetrates through the through hole 124 to be connected with the other insulating layer 120. Through set up through-hole 124 at metal level 122 and make the insulating layer 120 of metal level 122 both sides connect through-hole 124, can make the connection of metal level 122 and insulating layer 120 inseparabler, when flexible display panel 10 buckles, can reduce the risk of peeling off between metal level 122 and the adjacent insulating layer 120, and then the encapsulation effect of reinforcing non-display area 12 to promote user's use and experience.
Here, for example, the non-display region 12 may be provided with three insulating layers 120, the three insulating layers 120 may be a first insulating layer 120a, a second insulating layer 120b and a third insulating layer 120c, and the second insulating layer 120b is disposed between the first insulating layer 120a and the third insulating layer 120 c. A first metal layer 122a may be disposed between the first insulating layer 120a and the second insulating layer 120b, and a second metal layer 122b may be disposed between the second insulating layer 120b and the third insulating layer 120 c. The first metal layer 122a is closer to the display surface of the flexible display panel 10 than the second metal layer 122 b.
In a first case, please refer to fig. 1 to fig. 4, at least one first through hole 124a is disposed in the first metal layer 122a near the display surface of the flexible display panel 10. Accordingly, the first insulating layer 120a and the second insulating layer 120b at both sides of the first metal layer 122a may be connected through the first via 124 a. The connection between the first insulating layer 120a, the first metal layer 122a, and the second insulating layer 120b thus provided is tighter, thereby reducing the risk of peeling between the above three-layered structures when the flexible display panel 10 is bent.
Since the non-display area 12 is configured to fit the display area 11, the first metal layer 122a may have an irregular shape to fit the space occupying requirement of other components. In order to make the connection effect among the first metal layer 122a, the first insulating layer 120a and the second insulating layer 120b better, a plurality of first through holes 124a may be formed on the first metal layer 122 a. The plurality of first through holes 124a may be regularly arranged, and the number of the first through holes 124a located in the middle of the first metal layer 122a may be greater than the number of the first through holes 124a located at the edge of the first metal layer 122a, which is determined by the shape of the first metal layer 122a, for example, the first metal layer 122a may have a shape gradually shrinking from the middle to the edge.
Here, the material of the first insulating layer 120a may be the same as the material of the second insulating layer 120 b. It should be noted that, compared to the distance between the second insulating layer 120b and the display surface of the flexible display panel 10, the first insulating layer 120a is closer to the display surface of the flexible display panel 10, and the first metal layer 122a, the first insulating layer 120a and the second insulating layer 120b may be a layer structure prepared following the preparation of the display region 11. For example, the first insulating layer 120a may be a passivation layer, and may also be denoted as a PVS layer. The first metal layer 122a may be a metal layer formed following the source-drain metal layer preparation of the display region 11. The first insulating layer 120a is used to cover the first metal layer 122a to prevent the first metal layer 122a from being exposed and oxidized. The second insulating layer 120b includes an interlayer dielectric layer and a buffer layer, and the first and second insulating layers 120a and 120b may be positioned at both sides of the first metal layer 122 a. Illustratively, the material of each of the first insulating layer 120a and the second insulating layer 120b may be SiO. Since the adhesion of the metal to the SiO is small, the insulating layer and the metal layer are easily peeled off when the flexible display panel 10 is bent. In the embodiment of the present application, the plurality of through holes 124 may be disposed on the metal layer 122 to connect the insulating layers 120 on two sides of the metal layer 122, so as to improve the adhesion between the metal layer 122 and the insulating layers 120 on two sides of the metal layer, and further improve the packaging effect of the non-display area 12.
In a second exemplary case, please refer to fig. 5 in combination with fig. 1 to 4, and fig. 5 is a second cross-sectional view of a portion of the structure in the non-display area of the flexible display panel shown in fig. 2. The first metal layer 122a close to the display surface of the flexible display panel 10 is provided with at least one first through hole 124a, and the second metal layer 122b far from the display surface of the flexible display panel 10 is provided with at least one second through hole 124 b. Each second through hole 124b is disposed offset from each first through hole 124 a. The second metal layer 122b is provided with at least one second through hole 124b, so that the second insulating layer 120b and the third insulating layer 120c on both sides of the second metal layer 122b can be connected through the second through hole 124b, and the connection among the second metal layer 122b, the second insulating layer 120b and the third insulating layer 120c can be made tighter. Meanwhile, the first metal layer 122a is provided with at least one first via 124a to connect the first insulating layer 120a and the second insulating layer 120b, so that the connection between the first metal layer 122a, the first insulating layer 120a, and the second insulating layer 120b can be made tighter. In summary, the arrangement of the at least one first via 124a in the first metal layer 122a and the arrangement of the at least one second via 124b in the second metal layer 122b can make the connection among the first insulating layer 120a, the second insulating layer 120b, the third insulating layer 120c, the first metal layer 122a and the second metal layer 122b tighter, so that the different material layers of the non-display area 12 are not easily peeled off, thereby improving the packaging effect of the non-display area 12.
It is understood that the second metal layer 122b may be disposed between the second insulating layer 120b and the third insulating layer 120 c. The third insulating layer 120c is disposed on a side away from the display surface of the flexible display panel 10 compared to the first insulating layer 120 a. The third insulating layer 120c may also be referred to as a polyimide film layer (PI), which may be used as a base material layer. The third insulating layer 120c and the second metal layer 122b are also layer structures prepared following the preparation of the components in the display area 11. The material of the third insulating layer 120c may be the same as the material of the first insulating layer 120a, for example, the material of the third insulating layer 120c is also SiO.
It should be noted that the second metal layer 122b may also be referred to as a first metal layer or an LS layer, the second metal layer 122b may be a first metal layer disposed when the flexible display panel 10 is manufactured, and the second metal layer 122b may be a light shielding layer or a base layer of metal traces, so as to stabilize light emission of the flexible display panel 10. The second metal layer 122b may be electrically connected to the first metal layer 122a, for example, a through hole may be formed on the second insulating layer 120b, and a portion of the first metal layer 122a is disposed in the through hole and connected to the second metal layer 122b, so as to meet the routing requirement of the flexible display panel 10. The areas of the second metal layer 122b and the first metal layer 122a may be equal and are arranged up and down correspondingly, so that the connection between the second metal layer 122b and the first metal layer 122a is facilitated.
In a third exemplary case, please refer to fig. 6 in combination with fig. 1 to 5, and fig. 6 is a third schematic cross-sectional view of a portion of the structure in the non-display area of the flexible display panel shown in fig. 2. On the basis of the second situation, that is, at least one first through hole 124a is disposed on the first metal layer 122a, at least one second through hole 124b is disposed on the second metal layer 122b, and at least one third through hole 124c is disposed on the second insulating layer 120b, the first insulating layer 120a may be connected to the third insulating layer 120c through the third through hole 124c, so that the connection tightness between the three insulating layers 120 and the two metal layers 122 sandwiched between the three insulating layers 120 may be further increased, and thus the different material layers are not easily peeled off when the flexible display panel 10 is bent. The encapsulation effect of the non-display area 12 is improved.
For example, each third through hole 124c may be spaced apart from the first metal layer 122a by a predetermined distance, for example, the predetermined distance may be 0.01 mm. Of course, each third via 124c may also be adjacent to the first metal layer 122a, so as to make the connection between the insulating layers 120 close to the metal layer 122 tight, thereby helping the connection between the metal layer 122 and the insulating layer 120 to be tighter.
In order to solve the problem that different material layers are easy to peel off, the embodiments of the present application are not limited to the above solutions, that is, the three cases correspond to the above examples. Other solutions will be explained below.
Illustratively, please continue to refer to fig. 2. The embodiment of the present application further provides a flexible display panel 10, where the flexible display panel 10 may include a display area 11 and a non-display area 12, and the non-display area 12 may be disposed around the display area 11. For the description of the display area 11, reference may be made to fig. 1 and fig. 2 and the above description, which are not repeated herein. The non-display area 12 of the embodiment of the present application may include at least three insulating layers 120, and a metal layer 122 is disposed between two adjacent insulating layers 120. At least one of the insulating layers is provided with at least one through hole 124, and one of the insulating layers 120 on both sides of the insulating layer 120 provided with the through hole 124 passes through the through hole 124 and is connected with the insulating layer 120 on the other side. Because the metal layers 122 are sandwiched between the insulating layers 120, if the insulating layer 120 on both sides is connected by forming the through hole 124 in the middle insulating layer 120 of the at least three insulating layers 120, the connection between the three insulating layers 120 and the metal layers 122 sandwiched between the insulating layers 120 is tighter, thereby reducing the risk of peeling between different material layers when the flexible display panel 10 is bent.
In a fourth exemplary case, please refer to fig. 7 and 8 in combination with fig. 1 to 6, where fig. 7 is a fourth cross-sectional view of a partial structure in a non-display area of the flexible display panel shown in fig. 2, and fig. 8 is a fifth cross-sectional view of a partial structure in a non-display area of the flexible display panel shown in fig. 2. The at least three insulating layers 120 may include a first insulating layer 120a, a second insulating layer 120b, and a third insulating layer 120c, with the second insulating layer 120b interposed between the first insulating layer 120a and the third insulating layer 120 c. Accordingly, a first metal layer 122a may be disposed between the first insulating layer 120a and the second insulating layer 120b, and a second metal layer 122b may be disposed between the second insulating layer 120b and the third insulating layer 120 c. For the material composition and the arrangement manner of the layer structure of the first insulating layer 120a, the second insulating layer 120b, and the third insulating layer 120c, and the first metal layer 122a and the second metal layer 122b, reference may be made to fig. 1 to fig. 7 and the above description, which are not repeated herein. Wherein the second insulating layer 120b may be provided with at least one third via 124 c. The first insulating layer 120a may be connected to the third insulating layer 120c through the third via 124c, thereby making the connection between the three insulating layers 120 and the two metal layers 122 tighter.
