Description
Technical Field
The embodiment of the invention relates to the technical field of display devices, in particular to a display panel bracket and a display device.
Background
As the development demand of display products, the application of hard screen display devices is increasingly limited, and flexible display devices are receiving more and more attention due to their many unique properties.
Fig. 1 is a schematic structural diagram of a conventional flexible display device, and fig. 2 is a schematic structural diagram of the flexible display device in fig. 1 in a bent state. Referring to fig. 1 and 2, the flexible display device includes a support and a flexible display panel 104; wherein, the flexible display device can be divided into a first region 101, a second region 102 and a third region 103; the support comprises a first support 111 located in the first area 101 and a second support 112 located in the second area 102, and the first support 111 and the second support 112 are connected by a hinge 113 located in the third area 103. The portion of the flexible display panel 104 located in the first region 101 is fixed and attached to the first support 111, the portion of the flexible display panel 104 located in the second region 102 is fixed and attached to the second support 112, and the first support 111 and the second support 112 are used for fixing the relative position of the flexible display panel 104 on the supports. In consideration of the reasonable application and the aesthetic appearance of the flexible display device in the terminal, the hinge 113 is often disposed at a position away from the light-emitting side of the flexible display panel 104.
If the length of the hinge 113 between the first bracket 111 and the second bracket 112 is L, the length of the flexible display panel 104 in the third region 103 when the flexible display device is not bent is also L. When the flexible display panel 104 is in the bent state, as shown in fig. 2, since the length L of the hinge 113 is not changed, the distance between the first support 111 and the second support 112 is still L along the curved path of the hinge 113. However, when the flexible display panel 104 is in the bent state, as shown in fig. 2, the arc formed by the portion of the flexible display panel 104 located in the third region 103 is surrounded by the arc formed by the hinge 113, and therefore, the length of the portion of the flexible display panel 104 located in the third region 103 is less than L. Therefore, when the flexible display device is bent from the state shown in fig. 1 to the state shown in fig. 2, the portion of the flexible display panel 104 located in the third region 103 should become small. However, since the first bracket 111 and the second bracket 112 are attached to the flexible display panel 104 in the first region 101 and the second region 102, respectively, the length of the portion of the flexible display panel 104 in the third region 103 cannot be reduced, which causes stress to be generated in the flexible display panel 104 in the third region 103 and may cause separation or breakage of the film layer of the flexible display panel 104 in the third region 103.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Fig. 3 is a schematic structural diagram of a display panel bracket according to an embodiment of the present invention, fig. 4 is a schematic structural diagram of a display panel bracket and a supported display panel according to an embodiment of the present invention, and fig. 5 is a schematic structural diagram of the display panel bracket and the supported display panel in fig. 4 after being bent. Specifically, referring to fig. 3 to 5, the display panel bracket includes: a first support region 201, a second support region 202, and a bending corresponding region 203 located between the first support region 201 and the second support region 202; the display panel bracket further includes: a first hinge fixing block 301 and a second hinge fixing block 302; the first hinge fixing block 301 is located on one side of the first supporting area 201 close to the bending corresponding area 203, and the second hinge fixing block 302 is located on one side of the second supporting area 202 close to the bending corresponding area 203; the first hinge fixing block 301 and the second hinge fixing block 302 are connected through a hinge 204; the hinge 204 is located in the bending corresponding area 203; at least one first active block 401 and at least one second active block 402; the at least one first movable block 401 is positioned on one side of the first hinge fixed block 301, which is far away from the second hinge fixed block 302, and the at least one second movable block 402 is positioned on one side of the second hinge fixed block 302, which is far away from the first hinge fixed block 301; the first hinge fixed block 301, the second hinge fixed block 302, the at least one first movable block 401 and the at least one second movable block 402 are attached to the supported display panel 205 through non-contact attachment force; and in the process of bending the supported display panel 205, the first hinge fixed block 301, the second hinge fixed block 302, the at least one first movable block 401 and the at least one second movable block 402 can move relative to the supported display panel 205.
Specifically, when the display panel bracket and the supported display panel 205 are not bent, assuming that the length of the hinge 204 is L, the length of the supported display panel 205 located in the bending corresponding region 203 is also L at this time. The length of the hinge 204 is still L along the bending direction of the hinge 204 during and after the display panel bracket and the supported display panel 205 are bent. However, during and after the bending of the display panel bracket and the supported display panel 205, since the hinge 204 always surrounds the supported display panel 205 in the bending corresponding region 203, the length of the hinge 204 is greater than the length of the supported display panel 205 in the bending corresponding region 203 according to the geometric relationship. Therefore, when the supported display panel 205 is gradually bent from the state shown in fig. 4 to the state shown in fig. 5, the length of the supported display panel 205 located in the bending corresponding region 203 tends to gradually decrease due to the force of the display panel bracket on the supported display panel 205.
Since the first hinge fixing block 301, the second hinge fixing block 302, the at least one first movable block 401, and the at least one second movable block 402 are all attached to the supported display panel 205 by non-contact attaching force, the relative positional relationships between the first hinge fixing block 301, the second hinge fixing block 302, the at least one first movable block 401, and the at least one second movable block 402 and the supported display panel 205 are not completely fixed. In the process of bending the supported display panel 205, the first hinge fixed block 301, the second hinge fixed block 302, the at least one first movable block 401, and the at least one second movable block 402 may all move relative to the supported display panel 205, so that the length of the bent display panel 205 located in the bending corresponding region 203 may gradually change from L to a value smaller than L, and in this process, the stress formed by the first hinge fixed block 301, the second hinge fixed block 302, the at least one first movable block 401, and the at least one second movable block 402 on the supported display panel 205 is released. Therefore, in the process of bending the supported display panel 205, the display panel bracket provided by this embodiment can prevent the film layer in the supported display panel 205 from separating or breaking.
It is noted that in fig. 3, 4 and 5, the number of the at least one first active block 401 and the at least one second active block 402 is 2, but it should be understood that this is only an exemplary configuration. In practical applications, the number of the first active blocks 401 may be one or any number, and the number of the second active blocks 402 may also be one or any number. It should be noted that the main function of the display panel bracket is to support the display panel, and therefore, in order to clearly describe the structure and function of the display panel bracket, the present embodiment is provided with the supported display panel 205. It should be understood that the display panel stand provided by the present embodiment does not rely on the supported display panel 205 as a complete product.
The display panel bracket provided by the embodiment comprises a first hinge fixed block, a second hinge fixed block, at least one first movable block and at least one second movable block; and the first hinge fixed block, the second hinge fixed block, the at least one first movable block and the at least one second movable block structure are attached to the supported display panel by adopting non-contact attaching force, and in the process of bending the supported display panel, the first hinge fixed block, the second hinge fixed block, the at least one first movable block and the at least one second movable block structure can move relative to the supported display panel, so that the stress generated by the supported display panel in the bending process can be released, and the film layer separation or the fracture of the supported display panel can be avoided.
Fig. 6 is a schematic structural diagram of another display panel bracket and a supported display panel according to an embodiment of the present invention. Optionally, referring to fig. 5, the display panel bracket further includes a plurality of first magnetic field generating units 501; the first hinge fixing block 301, the second hinge fixing block 302, the first movable block 401, and the second movable block 402 are provided with a first magnetic field generating unit 501 at a side close to the supported display panel 205.
Specifically, after the first magnetic field generating unit 501 is disposed on one side of the first hinge fixed block 301, the second hinge fixed block 302, the first movable block 401, and the second movable block 402, which is close to the supported display panel 205, if the corresponding magnetic field generating units are also disposed at corresponding positions on the supported display panel 205, by reasonably setting the polarity of the magnetic field, when the magnetic field generating units on the first magnetic field generating unit 501 and the supported display panel 205 generate magnetic fields simultaneously, the first hinge fixed block 301, the second hinge fixed block 302, the first movable block 401, and the second movable block 402 can form non-contact attaching force with the supported display panel 205 respectively by using the principle that different magnetic poles attract each other. On one hand, the non-contact attaching force may fix the relative positions between the supported display panel 205 and the first hinge fixing block 301, the second hinge fixing block 302, the first movable block 401, and the second movable block 402 to some extent; on the other hand, when the supported display panel 205 is subjected to a large stress parallel to the surface of the supported display panel 205, the supported display panel 205 may also move relative to the first hinge fixing block 301, the second hinge fixing block 302, the first movable block 401, and the second movable block 402, thereby preventing the film in the supported display panel 205 from being separated or broken.
Optionally, the display panel support further comprises a plurality of first electric field generating units; the first hinge fixing block, the second hinge fixing block, the first movable block and the second movable block are close to one side of the supported display panel and are provided with first electric field generating units.
Specifically, the charges with different electric properties may attract each other, and the magnetic poles with different magnetic properties may attract each other. Therefore, when the first electric field generating unit is arranged on one side of the first hinge fixing block, the second hinge fixing block, the first movable block and the second movable block close to the supported display panel, the first magnetic field generating unit is arranged in the structure, and the first electric field generating unit has the same beneficial effects and is not repeated.

Optionally, referring to fig. 7, the display panel bracket provided in this embodiment further includes a plurality of second magnetic field generating units 502; second magnetic field generating units 502 are respectively arranged on the opposite surfaces of the first hinge fixed block 301 and the adjacent first movable block 401; second magnetic field generation units 502 are provided on the surfaces of the adjacent first movable blocks 301 facing each other.

Similarly, the second magnetic field generation units 502 are disposed on the surfaces of the adjacent first movable blocks 301, respectively, so that each first movable block 301 can be located at an optimal position.
Similarly, second magnetic field generating units 502 are respectively disposed on the surfaces of the second hinge fixed block 302 opposite to the adjacent second movable block 402; the second magnetic field generating units 502 are respectively disposed on the opposite surfaces of the adjacent second movable blocks 402, which also has similar beneficial effects and will not be described again.

Specifically, the second electric field generating units are respectively disposed at the above positions, and have the same beneficial effects as the second magnetic field generating units are respectively disposed at the above positions, and are not described again.
Fig. 8 is a schematic structural diagram of another display panel bracket according to an embodiment of the present invention, and fig. 9 is a schematic structural diagram of another display panel bracket according to an embodiment of the present invention. Optionally, referring to fig. 8 and 9, the display panel bracket provided in this embodiment further includes a plurality of springs 601, where the springs 601 extend along the arrangement direction of the first hinge fixing block 301 and the second hinge fixing block 302; at least one spring 601 is arranged between the first hinge fixed block 301 and the adjacent first movable block 401; at least one spring 601 is arranged between the adjacent first movable blocks 301; at least one spring 601 is arranged between the second hinge fixed block 302 and the adjacent second movable block 402; at least one spring 601 is arranged between the adjacent second movable blocks 402.
