The following describes a technical solution of an embodiment of the present application.
As shown in fig. 2 to 7, an embodiment of the present application provides a display assembly, including: the organic light emitting display panel 1, the organic light emitting display panel 1 includes a display portion 11, a bending portion 12 and a connecting portion 13, the display portion 11 is connected to the connecting portion 13 through the bending portion 12, the display portion 11 has a light emitting surface 111 and a non-light emitting surface 112 opposite to the light emitting surface 111, the bending portion 12 is a bending structure, when the display panel is bent, the connecting portion 13 is located on one side of the non-light emitting surface 112 of the display portion 11, the bending portion 12 includes an inner surface 122 and an outer surface 121 which are oppositely arranged, the outer surface 121 of the bending portion 12 is connected to the light emitting surface 111 of the display portion 11, and the inner surface 122 of the bending portion 12 is connected to the non-light emitting surface 112 of the display portion 11; the bent portion 12 includes a first magnetic layer 21; a second magnetic layer 22 located on the outer surface 121 side or the inner surface 122 side of the bent portion 12, the second magnetic layer 22 and the first magnetic layer 21 being disposed at an interval, one end of the second magnetic layer 22 being fixed to the first fixing portion 31 located on the display portion 11, and the other end of the second magnetic layer 22 being fixed to the second fixing portion 32 located on the connecting portion 13; the second magnetic layer 22 serves to provide an attractive or repulsive force with the first magnetic material layer 21.
Specifically, the display portion 11 of the organic light emitting display panel 1 includes a light emitting device, a pixel driving circuit, a package layer, and the like, and is configured to implement image display, where the light emitting device emits light from the light emitting surface 111 side, the number of the film layers of the bending portion 12 is small, and the bending portion generally includes a signal line and an insulating layer, where the signal line is mainly used to implement signal transmission between the display portion 11 and the connecting portion 13, the connecting portion 13 is used to bond a flexible circuit board and connect a motherboard through the flexible circuit board, and the connecting portion 13 may also bond a chip or connect a chip through the flexible circuit board. Since the first magnetic layer 21 belongs to the bending portion 12 and both ends of the second magnetic layer 22 are respectively fixed to the display portion 11 and the connecting portion 13, when an attractive force or a repulsive force that interacts with each other is generated between the first magnetic layer 21 and the second magnetic layer 22 due to magnetism, the bending portion 12 of the organic light emitting display panel 1 is bent, for example, an unbent structure shown in fig. 3 is changed into a bent structure shown in fig. 7, the bending portion 12 is subjected to a uniform magnetic force during the bending process, and the attractive force or the repulsive force with a uniform magnitude in a normal direction is always maintained between the first magnetic layer 21 and the second magnetic layer 22, so that the stress can be more uniformly released during the bending of the bending portion 12, thereby facilitating to maintain the bending form, ensuring that the bending portion 12 always maintains a certain bending radius during the whole bending process, improving the risk of occurrence of poor dead bending due to an operator's manipulation or uncontrollable external force, and improving the reliability of the bending area, and thus improving the yield of the flexible panel.

In one possible embodiment, the first magnetic layer 21 is a coating of magnetic material; the second magnetic layer 22 includes a magnetic material.

In one possible embodiment, the first magnetic layer 21 is a coating of a magnetic material; as shown in fig. 4 and 8, the second magnetic layer 22 includes an electromagnetic coil 220. That is, in addition to generating an attractive force or a repulsive force between the first magnetic layer 21 and the second magnetic layer 22 by using a permanent magnetic material, a magnetic field may be generated by the electromagnetic coil 220, and thus an attractive force or a repulsive force may be generated between the first magnetic layer 21 and the second magnetic layer 22, two terminals 221 may be respectively led out from both ends of the electromagnetic coil 220, and the two terminals 221 may be respectively fixed on the surfaces of the first fixing portion 31 and the second fixing portion 32, for example, so as to connect external leads, before the bending process of the organic light emitting display panel 1 is performed, the two terminals 221 at both ends of the electromagnetic coil 220 may be connected by the external leads, a voltage may be applied to both ends of the electromagnetic coil 220, so as to generate a current in the electromagnetic coil 220, and thus generate a magnetic field, and at this time, an attractive force or a repulsive force interacting with each other may be generated between the first magnetic layer 21 and the second magnetic layer 22, and then, the bending process of the organic light emitting display panel 1 may be started, even if the bending portion 12 of the organic light emitting display panel 1 is bent, the structure is changed from the structure after the structure as shown in fig. 7, for example, the structure shown in fig. 3, and the bending portion 12 is subjected to a uniform magnetic force during the bending process, so that the bending process of the bending, the bending portion 12 can be more uniformly released, thereby, and the stress can be more uniformly maintained, and the stress can be advantageously reduced. After the bending is completed, the external lead wire for supplying voltage to the electromagnetic coil 220 may be removed, the electromagnetic coil 220 is not required to continuously generate a magnetic field, and the organic light emitting display panel 1 may not be affected by the magnetic field of the electromagnetic coil 220 during normal operation. The attractive or repulsive force between the first magnetic layer 21 and the second magnetic layer 22 is generated by the electromagnetic coil 220, and the magnitude of the attractive or repulsive force can be controlled by the current passed in the electromagnetic coil 220, as compared to the use of a permanent magnetic material to generate the attractive or repulsive force between the first magnetic layer 21 and the second magnetic layer 22, to achieve more flexible adjustment.

In one possible embodiment, the resilient shell 222 is a polycarbonate material. The elastic shell 222 is made of an elastic material with a certain hardness, and the elastic shell 222 can be made of a material with a good resilience, such as a polycarbonate material, so that the elastic shell 222 cannot collapse and sag in the bending process and can keep a smooth arc shape, and therefore, in the bending process of the bending portion 12, because magnetic force exists between the electromagnetic coil 220 and the second magnetic layer 22, the bending portion 12 can always keep a certain radian, and dead fold and other situations cannot occur.
In one possible embodiment, as shown in fig. 4 and 8, the second magnetic layer 22 is fixedly connected to the first fixing portion 31 by a double-sided adhesive tape 223, and the second magnetic layer 22 is fixedly connected to the second fixing portion 32 by the double-sided adhesive tape 223. For example, the first fixing portion 31 is a double-layer structure, the elastic casing 222 is located between the double-layer structures of the first fixing portion 31, wherein the upper surface of the elastic casing 222 is adhered to the lower surface of the upper layer of the first fixing portion 31 through the double-sided tape 223, the lower surface of the elastic casing 222 is adhered to the upper surface of the lower layer of the first fixing portion 31 through the double-sided tape 223, the second fixing portion 32 is a double-layer structure, the elastic casing 222 is located between the double-layer structures of the second fixing portion 32, wherein the upper surface of the elastic casing 222 is adhered to the lower surface of the upper layer of the second fixing portion 32 through the double-sided tape 223, and the lower surface of the elastic casing 222 is adhered to the upper surface of the lower layer of the second fixing portion 32 through the double-sided tape 223. Therefore, the fixing effect of the elastic shell 222 is improved, and the probability that the elastic shell 222 is separated from the first fixing part 31 or the second fixing part 32 due to good resilience is reduced.
