The circuit layer 111 may be electrically connected to the first circuit board 101 and the second circuit board 102 directly, or may be electrically connected to each other through another connecting member (e.g., a conductive adhesive or a thermocompression bonding member). The first circuit board 101 may also be called a main board for carrying electronic components and transmitting signals, and the second circuit board 102 may also be called a sub-board for carrying electronic components and transmitting signals.

It will be appreciated that a single piece of sheet metal may be used to support the folded screen and to provide the wiring layer 111, reducing the use of the device and thus the space occupied by the device in the cavity 105. Furthermore, the first foldable support sheet 110 is attached to one side of the flexible screen 104, which reduces the mobility of the first foldable support sheet 110 in the inner cavity 105, thereby improving the stability of the circuit structure.
As shown in fig. 1, in one embodiment, the circuit structure further includes a first flexible wiring board 112 and a second flexible wiring board 113;

The second end of the first flexible printed circuit 112 may be electrically connected to the first end of the first circuit board 101 directly, or may be electrically connected through another connecting component, so that one end of the circuit layer 111 is connected to the first end of the first circuit board 101 through the first flexible printed circuit 112, and one end of the circuit layer 111 may transmit signals between the first flexible printed circuit 112 and the first circuit board 101. The second end of the first circuit board 101 and the third end of the first flexible circuit board 112 may be directly electrically connected, or may be electrically connected through other connecting members, and the fourth end of the first flexible circuit board 112 and the flexible screen 104 may be directly electrically connected, or may be electrically connected through other connecting members, so that the second end of the first circuit board 101 is connected to the flexible screen 104 through the first flexible circuit board 112, and the second end of the first circuit board 101 may transmit signals between the first flexible circuit board 112 and the flexible screen 104. The other end of the circuit layer 111 may be directly electrically connected to one end of the second flexible printed circuit 113, or may be electrically connected to the other end of the second flexible printed circuit 113 through another connecting component, or may be electrically connected to the second circuit board 102 through another connecting component, so that the other end of the circuit layer 111 may be connected to the second circuit board 102 through the second flexible printed circuit 113, and the other end of the circuit layer 111 may transmit signals between the second flexible printed circuit 113 and the second circuit board 102.

As shown in fig. 2, in one embodiment, the first foldable support sheet 110 is spaced apart from the flexible screen 104, the circuit structure further includes a third flexible printed circuit 114, one end of the first circuit board 101 is connected to the flexible screen 104 through the third flexible printed circuit, and the other end of the first circuit board 101 is connected to one end of the second circuit board 102 through the circuit layer 111.
In this embodiment, the first foldable support sheet 110 and the flexible screen 104 are spaced apart from each other, so that a degree of freedom exists between the first foldable support sheet 110 and the flexible screen 104, and the flexible screen 104 can be prevented from damaging the first foldable support sheet 110 during the bending process. In addition, in one example, the foldable area of the first foldable support sheet 110 is disposed opposite to the foldable area of the flexible screen 104, such that the foldable area of the first foldable support sheet 110 is bent during the bending of the flexible screen 104, thereby improving the bending performance.
As shown in fig. 2, in one embodiment, the circuit structure further includes a second foldable support sheet 115 attached to a side of the flexible screen 104 facing the inner cavity 105 for supporting the flexible screen 104;
the second foldable support sheet 115 is positioned between the flexible screen 104 and the first foldable support sheet 110, and the foldable area of the second foldable support sheet 115 is positioned opposite the foldable area of the first foldable support sheet 110.
The second foldable support sheet 115, which may also be referred to as a bendable support layer or a bendable support layer, is attached to the side of the flexible screen 104 facing the inner cavity 105, which reduces the mobility of the foldable metal support in the inner cavity 105, thereby improving the stability of the circuit structure, and the second foldable support sheet 115 is attached to the flexible screen 104, which can provide support for the flexible screen 104, while the foldable area of the second foldable support sheet 115 is disposed opposite to the foldable area of the first foldable support sheet 110, and the foldable area of the second foldable support sheet 115 and the foldable area of the first foldable support sheet 110 can be bent along with the bending of the flexible screen 104, i.e. in case of the bending of the flexible screen 104, the foldable area of the first foldable support sheet 110 is bent, and the foldable area of the second foldable support sheet 115 is bent, and the foldable area has a bendable performance, thereby improving the overall bending performance of the circuit structure.
As one example, the second foldable support sheet 115 may be a second foldable metal sheet, which may include, but is not limited to, a foldable stainless steel support layer. Due to the property of the second foldable metal sheet, the second foldable metal sheet can bear bending for many times, is not easy to deform, enables the circuit structure not to deform easily, and prolongs the service life of the circuit structure. In addition, the second foldable support sheet 115 of the present embodiment may include a third region 1151, a fourth region 1152, and a foldable region 1153 of the second foldable support sheet 115 connected between the third region 1151 and the fourth region 1152, the foldable region 1153 of the second foldable support sheet 115 may be attached to a side of the foldable screen region 1043 facing the inner cavity 105, the third region 1151 may be attached to a side of the first screen region 1041 facing the inner cavity 105, and the fourth region 1152 may be attached to a side of the second screen region 1042 facing the inner cavity 105. In this way, in case the flexible screen 104 is bent, the foldable area 1103 of the first foldable support sheet 110 is bent, and the foldable area 1153 of the second foldable support sheet 115 is bent, and the foldable area has a bendable performance, so that the bending performance of the entire wiring structure can be improved.
As shown in fig. 2, in one embodiment, the foldable area of the second foldable support sheet 115 is a foldable area with an openwork structure.
Since the foldable area of the second foldable support sheet 115 is a hollow-out foldable area, the foldable area can extend along both sides due to the hollow-out area during the bending process to buffer the bending stress, thereby improving the bending performance of the foldable area of the second foldable support sheet 115 and improving the bending life of the second foldable support sheet 115.
As shown in fig. 1-2, in one embodiment, the first foldable support sheet 110 comprises a first region 1101, a second region 1102, and a foldable connection region 1103 connected between the first region 1101 and the second region 1102;
the foldable connection area 1103 is attached to a surface of the foldable screen area 1043 facing the inner cavity 105, or the foldable connection area 1103 and the foldable screen area 1043 are opposite and spaced apart from each other.
The foldable area of the first foldable support sheet 110 is the foldable connection area 1103, and the foldable connection area 1103 is attached to a side of the foldable screen area 1043 facing the inner cavity 105, so that the mobility of the first foldable support sheet 110 in the inner cavity 105 is reduced, thereby improving the stability of the circuit structure. Or the foldable connection region 1103 and the foldable screen region 1043 are disposed opposite to each other at an interval, the interval may enable a degree of freedom between the first foldable support sheet 110 and the flexible screen 104, so as to prevent the flexible screen 104 from damaging the first foldable support sheet 110 during the bending process, and the opposite arrangement may enable the foldable region of the first foldable support sheet 110 to be bent during the bending process of the foldable screen, thereby improving the bending performance.
In one embodiment, the foldable connection region 1103 is a foldable region with an open structure, and the wires 11121 of the circuit layer 111 are disposed to fit against the surface of the foldable connection region 1103 on the surface of the foldable connection region 1103 facing the inner cavity 105.
Because the foldable connection region 1103 has a hollow structure, the foldable connection region 1103 can extend along two sides due to the hollow area during the bending process, so as to buffer the bending stress, improve the bending performance of the foldable connection region 1103, and further improve the bending life of the foldable connection region 1103. Meanwhile, wiring can be performed on the surface of the foldable connection region 1103 facing the inner cavity 105, and the lead 11121 of the wiring layer 111 is arranged to be attached to the surface of the foldable connection region 1103, so that wiring of the lead 11121 on the surface of the foldable connection region 1103 can be realized, and thus, the lead 11121 of the wiring layer 111 on the surface of the foldable connection region 1103 can be wired in accordance with the shape of the surface of the foldable connection region 1103, and the stability of wiring of the lead 11121 of the wiring layer 111 on the surface of the foldable connection region 1103 can be improved.
For example, as shown in fig. 4-6, the foldable connection region 1103 of the first foldable support sheet 110 includes a metal suspension wire 11031, and the metal suspension wire 11031 forms a hollow area, for example, as shown in fig. 4, the hollow area may include a first hollow area 11032 and a second hollow area 11033, and the conductive wire 11121 of the circuit layer 111 may be routed on the surface of the metal suspension wire 11031 of the foldable connection region 1103.
As shown in fig. 7, it is a schematic diagram of routing (routing) of the conductive wire 11121 on the surface of the foldable connection area 1103, the routing is along the black "what" is "routing in fig. 7, and the surface of all the" what "is" metal suspension wires 11031 in the hollow area in fig. 7 can be routed. As shown in fig. 8, besides the trace shape shown in fig. 7, other trace shapes are possible, for example, the hollow structure of the foldable connection region 1103 may be a comb shape, and the surface of the "straight" metal suspension wire 11031 in fig. 8 may be wired.
