Specific implementations of the present application will be described in detail below with reference to the accompanying drawings.
To better describe the technical solution provided by the embodiment of the present application, please refer to fig. 1 and fig. 2, in which fig. 1 shows a schematic view of a partial structure of a flexible display panel provided by the embodiment of the present application, and fig. 2 shows one of schematic views of a connection structure between adjacent pixel islands provided by the embodiment of the present application.
The flexible display panel 1 may include a flexible substrate 10, a plurality of pixel islands 20 on the flexible substrate 10, and a connection structure 30 for connecting adjacent pixel islands 20.
The flexible substrate 10 may be made of a flexible material, and the flexible substrate 10 may be stretched by a large amount without being broken under a tensile force and may be rapidly restored after the tensile force disappears. For example, the flexible material may be rubber, organic plastic, or the like, and in the embodiment of the present application, the specific material of the flexible substrate 10 is not limited. It is understood that materials with better flexibility are possible for the flexible substrate 10 in this embodiment. The pixel islands 20 are portions of the flexible display panel 1 for displaying, and generally, one pixel island 20 may include at least one pixel unit, and the pixel units in the pixel island 20 may emit light of different colors (for example, red light, green light, and blue light) when being powered on, so that the flexible display panel 1 can perform displaying. In the embodiment of the present application, the pixel unit for displaying in the pixel island 20 may be an Organic Light-Emitting Diode (OLED). It should be noted that, because the display panel formed by using the OLED has poor stretch resistance, the pixel islands 20 are usually configured as rigid islands, i.e., the pixel islands 20 are generally not or hardly stretched, so that the display panel formed by using the OLED can be prevented from being damaged by stretching.
The connection structure 30 may include a first conductive structure 31 and a second conductive structure 32 that are movably connected, wherein the first conductive structure 31 and the second conductive structure 32 are respectively connected to one of the adjacent pixel islands 20. For example, as shown in fig. 2, the first conductive structure 31 is connected to the pixel island 20 on the left side, and the second conductive structure 32 is connected to the pixel island 20 on the right side. The landing locations 40 of the first conductive structures 31 and the second conductive structures 32 are located between adjacent pixel islands 20. When the relative position of the adjacent pixel islands 20 is shifted, the overlapping area of the first conductive structure 31 and the second conductive structure 32 at the overlapping position 40 varies with the distance between the adjacent pixel islands 20. Specifically, with reference to fig. 2 and fig. 3, wherein fig. 3 is a state diagram of the adjacent pixel islands in fig. 2 in a stretching state, in the stretching process, as the distance between the adjacent pixel islands 20 becomes larger, the overlapping area of the first conductive structure 31 and the second conductive structure 32 at the overlapping position 40 becomes smaller; in the recovery process after stretching, as the distance between adjacent pixel islands 20 becomes smaller, the overlapping area of the first conductive structure 31 and the second conductive structure 32 at the overlapping position 40 becomes larger.
In the above structure provided by the embodiment of the present application, the adjacent pixel islands 20 are connected by the connection structure 30, the connection structure 30 is composed of the first conductive structure 31 and the second conductive structure 32 respectively connected to the adjacent pixel islands 20, and the first conductive structure 31 and the second conductive structure 32 are movably overlapped together. When the relative position of the adjacent pixel islands 20 is shifted, the first conductive structures 31 and the second conductive structures 32 move relatively, and the overlapping areas of the first conductive structures 31 and the second conductive structures 32 at the overlapping positions 40 vary with the distance between the adjacent pixel islands 20. In this way, even if the relative position of the adjacent pixel islands 20 moves, the first conductive structures 31 and the second conductive structures 32 are always connected in an overlapping manner, so that the display panel 1 can display normally in a stretching state.
Referring to fig. 4, fig. 4 shows a second schematic view of a connection structure 30 of adjacent pixel islands provided in the present embodiment, the connection structure 30 may further include a conductive connection structure 33, the conductive connection structure 33 is located between the first conductive structure 31 and the second conductive structure 32, wherein at least a portion of the conductive connection structure 33 is located at a joint position 40 of the first conductive structure 31 and the second conductive structure 32, and the conductive connection structure 33 is further in contact with the first conductive structure 31 and the second conductive structure 32, respectively.
Referring to fig. 4 and 5, fig. 5 shows a third schematic view of a connection structure 30 of adjacent pixel islands provided in the present embodiment, in a possible implementation manner of the present embodiment, the conductive connection structure 33 may be in contact with one pixel island 20 of the adjacent pixel islands 20, for example, as shown in fig. 4, the conductive connection structure 33 is in contact with the pixel island 20 located on the left side. In another possible implementation manner of the embodiment of the present application, the conductive connection structures 33 may also be respectively in contact with two adjacent pixel islands 20, for example, as shown in fig. 5.
Based on the above manner, the conductive connection structure 33 is disposed at the overlapping position 40 of the first conductive structure 31 and the second conductive structure 32, so that the problem that the flexible display panel 1 cannot be stretched due to the adhesion between the first conductive structure 31 and the second conductive structure 32 and the relative movement caused by the mutual diffusion of atoms in the first conductive structure 31 and the second conductive structure 32 can be avoided.
Further, referring to fig. 5 again, in a preferred implementation manner of the embodiment of the present application, the first conductive structure 31, the conductive connection structure 33, and the second conductive structure 32 are sequentially stacked in a direction perpendicular to the light exit surface of the flexible display panel 1. The two ends of the conductive connection structure 33 are respectively in contact with the adjacent pixel islands 20, and the conductive connection structure 33 includes a first conductive connection structure 331 covering the first conductive structure 31 and a second conductive connection structure 332 not covering the first conductive structure 31. In a direction perpendicular to the light emitting surface of the flexible display panel 1 (Y-axis direction in the figure), the sum of the thickness of the first conductive connection structure 31 and the thickness of the first conductive connection structure 331 is equal to the thickness of the second conductive connection structure 332.
With the above arrangement, the conductive connection structure 33 can have a flat surface on a side away from the flexible substrate 10 or the first conductive connection structure 331, so that when the second conductive structure 32 is manufactured, the second conductive structure 32 can be continuously formed on a flat surface, and the thickness of the film is uniform. As described above, in the present embodiment, the second conductive structure 32 can be formed by a wet process such as printing or spin coating.
Further, in the embodiment of the present application, the electrically conductive connection structure 33 may be made of a thermally conductive non-metallic material, and preferably, the thermally conductive non-metallic material may include graphene.
On the basis, the conductive connection structure 33 is made of a heat-conducting non-metallic material, so that on one hand, atomic diffusion between the first conductive structure 31 and the second conductive structure 32 can be prevented, and the first conductive structure 31 and the second conductive structure 32 are adhered to further influence the tensile property or cause the problem that the first conductive structure 31 and/or the second conductive structure 32 are broken in the tensile process. On the other hand, the heat generated when the first conductive structure 31 and the second conductive structure 32 move relative to each other can be uniformly dispersed through the conductive connection structure 33, so as to avoid the influence of the local over-high temperature on the display effect.
In the embodiment of the present application, the first conductive structure 31 and the second conductive structure 32 are alloy conductive structures. In detail, the alloy conductive structure may include at least one of a silver alloy conductive structure and an aluminum alloy conductive structure.
By designing the first conductive structure 31 and the second conductive structure 32 as alloy conductive structures, on the one hand, good conductive performance can be ensured; on the other hand, the first conductive structure 31 and the second conductive structure 32 can have a strong hardness, so as to ensure that the first conductive structure 31 and the second conductive structure 32 are not easily deformed during the relative movement.
Further, referring to fig. 6, fig. 6 shows a fourth schematic view of a connection structure 30 of adjacent pixel islands provided in the present embodiment, the connection structure 30 may further include a first protection layer 34 and a second protection layer 35, where the first protection layer 34 is located on a side of the first conductive structure 31 away from the second conductive structure 32, and the second protection layer 35 is located on a side of the second conductive structure 32 away from the first conductive structure 31. On the light exit surface of the flexible display panel 1, the orthographic projection of the first conductive structure 31 is located within the orthographic projection of the first protection layer 34, and the orthographic projection of the second conductive structure 32 is located within the orthographic projection of the second protection layer 35.
Based on the above arrangement, the first conductive structure 31 and the second conductive structure 32 may be protected by the first protective layer 34 and the second protective layer 35 to prevent the first conductive structure 31 and the second conductive structure 32 from being broken or warped.
In the embodiment of the present application, both ends of the first protective layer 34 and/or the second protective layer 35 are in contact with the adjacent pixel islands 20, respectively. The first protective layer 34 and the second protective layer 35 are made of a stretchable insulating material, preferably, the stretchable insulating material includes polydimethylsiloxane.
The first protective layer 34 and the second protective layer 35 are made of stretchable insulating materials, so that the first protective layer 34 and the second protective layer 35 deform when the adjacent pixel islands 20 move relatively, and the first conductive structure 31 and the second conductive structure 32 are protected, so that the first conductive structure 31 and the second conductive structure 32 are prevented from being broken or warped.
