Detailed Description
As described in the background art, there is a technical problem in the prior art that a display panel is abnormal due to a broken wire during a stretching process. The inventors have studied and found that the reason why such a problem occurs is as follows. The stretchable display panel in the prior art is usually provided with a plurality of pixel islands and wires connecting the pixel islands, and in the stretching process of the stretchable display panel, the wires cannot be stretched, but because the wires are usually made of metal and the like, the wires are poor in stretching resistance, and the wires may break in the stretching process, so that abnormal display, failure and even scrapping of a screen body are caused.
In order to solve the above problems, the inventors have found that, by providing a buffer device between at least one group of two adjacent pixel islands and disposing the wires in the buffer device, in the process of stretching the display panel, the stretching force acts on the buffer device first, and the buffer device shares the stretching force acting on the wires, thereby reducing the wire breakage probability and improving the service life of the display panel.
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of protection of the present invention.

Fig. 6 is a schematic structural diagram of another display panel according to an embodiment of the invention. As shown in fig. 1 and 6, the display panel includes a flexible substrate 1 and a plurality of pixel islands 2 disposed on the flexible substrate 1. Any two adjacent pixel islands 2 are electrically connected by a lead 3, and at least one group of two adjacent pixel islands 2 are fixedly connected by a buffer device 4. The wire 3 is arranged in the buffer 4.
In the embodiment of the invention, the buffer device 4 is arranged between at least one group of two adjacent pixel islands 2, and the lead 3 is arranged in the buffer device 4, so that in the process of stretching the display panel, the stretching force acts on the buffer device 4 firstly, and the buffer device 4 shares the stretching force acting on the lead 3, thereby reducing the breakage probability of the lead 3 and prolonging the service life of the display panel.
The flexible substrate 1 can be made of Polyimide (PI) materials which are commonly used in the industry, the PI materials have good flexibility, tolerance, expansion resistance, stress resistance and the like, can be bent and stretched repeatedly, can bear metal wires well and is high in process integration feasibility. In addition, the flexible substrate may be made of a nanocomposite material, polydimethylsiloxane (PDMS), or the like, so as to improve the bending stability of the display panel.
The pixel island 2 may include a thin film transistor layer (TFT layer) and an organic electroluminescent device layer (OLED layer) which are sequentially stacked along display light emission of the display panel. The shape of the pixel island 2 may be square, circular, oval, other polygons, and the like. The plurality of pixel islands 2 may be arranged in an array, or may be arranged according to other pixel arrangement requirements.
Fig. 2 is a schematic structural diagram of a buffer device connecting a group of two adjacent pixel islands in a display panel according to an embodiment of the present invention. As shown in fig. 2, a group of two adjacent pixel islands 2 are electrically connected by two wires 3, the buffer device 4 includes two tension buffer tubes 41, the two wires 3 are respectively disposed in the two tension buffer tubes 41, two ends of the tension buffer tube 41 are respectively fixedly connected to the group of two adjacent pixel islands 2, and the length of the tension buffer tube 41 is less than or equal to the length of the wire 3.
In the embodiment of the invention, a group of two adjacent pixel islands 2 are electrically connected by two wires 3, the two wires 3 are respectively arranged on two tension buffer tubes 41, because two ends of each tension buffer tube 41 are respectively fixedly connected with the group of two adjacent pixel islands 2 and the length of each tension buffer tube 41 is less than or equal to that of each wire 3, in the process of stretching the display panel, the tension stress acts on the tension buffer tubes 41 first, and the wires 3 are always in a relaxed state, thereby reducing the breaking probability of the wires 3. Every two adjacent pixel islands 2 of group on the display panel are all connected by the same structure, the probability that the wire 3 in the whole display panel is broken is reduced, and the service life of the display panel is prolonged.
Fig. 3 is a schematic structural diagram of a buffer device connecting a group of two adjacent pixel islands in a display panel and a constraint reset mechanism connected to the buffer device according to an embodiment of the present invention. As shown in fig. 3, the display panel further includes: and a constraint resetting mechanism 42, wherein the constraint resetting mechanism 42 is connected between the two tension buffer tubes 41 and is used for providing power opposite to the stretching direction for the flexible substrate 1. The connection of the restraint reset mechanism 42 between the two tension buffer tubes 41 fixes the position of the two tension buffer tubes 41 within a predetermined trajectory, preventing the tension buffer tubes 41 from tangling with each other. In addition, since the restraint resetting mechanism 42 provides the flexible substrate 1 with a power opposite to the stretching direction, after the flexible substrate 1 is stretched, the restraint resetting mechanism 42 provides the flexible substrate 1 with a force opposite to the stretching direction, that is, the flexible substrate 1 can be reset under the action of the force, that is, the display panel can be reset after being stretched.
In one embodiment, the restraint reset mechanism 42 includes a first elastic member connecting two tensile buffer tubes 41. When the display panel is not stretched, the length of the first elastic member is the length of the first elastic member under the action of no external force.
The first elastic member in the restraint reset mechanism 42 provides a force opposite to the stretching direction to the flexible substrate 1 by using its own elastic force. When the display panel is not stretched, the length of the first elastic element is equal to the length of the first elastic element under the action of no external force, that is, when the display panel is not stretched, the first elastic element is also in a non-stretched state, so that the tensile fatigue loss of the first elastic element is reduced, and the service life of the first elastic element is prolonged.

Fig. 5 is a schematic structural diagram of a buffer device connecting a group of two adjacent pixel islands in a display panel and another constraint reset mechanism connected to the buffer device according to an embodiment of the present invention.

As shown in FIG. 4, restraint reset mechanism 42 further includes: the slide 421, two sliding blocks 422 sliding in the slide 421, and a first elastic member 423, wherein two first ends of the two sliding blocks 422 departing from each other are respectively connected to the two tension buffer tubes 41, and two ends of the first elastic member 423 are respectively connected to two opposite second ends of the two sliding blocks 422. With reference to fig. 3, in the process that the display panel is stretched, the two tension buffer tubes 41 are stretched, and the distance between the two tension buffer tubes 41 is reduced, so as to drive the two sliding blocks 422 to move in the sliding ways 421 in opposite directions (that is, the two sliding blocks 422 in fig. 3 approach to the middle), so that the first elastic member 423 is compressed, and since the first elastic member 423 has an acting force opposite to the compression when being compressed, after the display panel is stretched, the acting force opposite to the compression can apply an acting force to the tension buffer tubes, and the acting force can provide a power opposite to the stretching direction for the flexible substrate 1, so as to assist the flexible substrate 1 to return from the stretched state to the unstretched state.

Referring to fig. 5, in the process of stretching the display panel, the two tension buffer tubes 41 are stretched, so that the distance between the two tension buffer tubes 41 is increased, and the two sliding blocks 422 are driven to move away from each other in opposite directions in the sliding ways 421 (that is, the two sliding blocks 422 are separated towards two sides in fig. 5), so that the first elastic member 423 is stretched, and since a force opposite to the stretching direction exists when the first elastic member 423 is stretched, the opposite force can provide a power opposite to the stretching direction for the flexible substrate 1, and the power-assisted flexible substrate 1 is restored to the unstretched state from the stretched state.
It should be understood that the structure of the restraint resetting mechanism 42 may be the structure shown in fig. 3, or the structure shown in fig. 5, and the restraint resetting mechanism 42 is only required to restrain the two tension buffer tubes 41 and provide the flexible substrate 1 with the power opposite to the stretching direction, and the specific structure of the restraint resetting mechanism 42 is not limited in the embodiment of the present invention.

Meanwhile, the second elastic member 43 can be restored in the elastic range, so that the second elastic member 43 restores the assisted elastic substrate from the stretched state to the unstretched state, thereby further prolonging the service life of the display panel.
