[0025] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution in the embodiment of the present invention will be clearly and completely described in combination with the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0026] See also Figure 1 , Figure 1 It is a schematic structural diagram of an embodiment of a display panel in the prior art.

[0027] In the prior art, the display area of ​​the display panel includes a rectangular area 11 and non-rectangular areas 12 located on the upper and lower sides of the rectangular area 11, and the corners of the outer edges of the non-rectangular area 12 are arc-shaped. The data line 13 extends in the relative direction of the two non-rectangular areas 12. The display panel also includes a control circuit 14, which is used to control the signal writing of the data line 13, and the control circuit 14 is usually located at the straight edge part at the bottom of the display panel.

[0028] Since the data line 13 extending from the arc-shaped corner of the non-rectangular area 12 needs to be electrically connected to the control circuit 14, the display panel is further provided with a fan-out line 15, and the data line 13 is electrically connected to the control circuit 14 through the fan-out line 15. Since the fan-out line 15 occupies too much frame space of the display panel, it is difficult to further reduce the frame of the display panel, which means that the frame size of the display panel in the prior art is large, which is not conducive to improving the screen-to-body ratio of the display panel.

[0029] In order to solve the technical problem of the excessive size of the display panel frame in the prior art, an embodiment of the present invention provides a display panel. The display panel includes at least two target signal lines, the target signal lines extend along the second direction, and the at least two target signal lines are sequentially spaced along the first direction, wherein the first direction and the second direction form a preset angle. The display panel also includes a control circuit, and the control circuit is located on at least one side of the at least two target signal lines in the first direction. The display panel also includes at least two connecting lines, at least a part of the connecting line extends along the first direction, and the at least two connecting lines are sequentially spaced along the second direction, wherein one end of the connecting line is electrically connected to the control circuit, and the other end is electrically connected to the corresponding target signal line. The following is a detailed description.

[0030] See also Figure 2 , Figure 2 It is a schematic structural diagram of a first embodiment of a display panel of the present invention.

[0031] In one embodiment, the display panel 20 includes at least two target signal lines 30, and the at least two target signal lines 30 are arranged along a first direction (eg Figure 2 As shown by the arrow X in the middle, the same below) are arranged in sequence, and each target signal line 30 is arranged along the second direction (such as Figure 2 The at least two target signal lines 30 have a first side and a second side in the first direction (the first side is as shown in FIG. Figure 2 As shown in A, the second side is Figure 2 As shown in B, the same below), the first side and the second side are two sides of the at least two target signal lines 30 as a whole in the first direction.

[0032] The first direction and the second direction form a preset angle. In other words, the first direction and the second direction are not parallel. The preset angle can be 90°, or an acute angle of 0° to 90°, or an obtuse angle of 90° to 180°. Preferably, the first direction is perpendicular to the second direction, such as Figure 2 shown.

[0033] The display panel 20 further includes a control circuit 40. The control circuit 40 is electrically connected to the at least two target signal lines 30, and is used to control the signal writing of the target signal lines 30, thereby driving the display panel 20 to emit light for display. Specifically, the control circuit 40 is located on one side of the at least two target signal lines 30 in the first direction, that is, the control circuit 40 is located on the first side or the second side mentioned above.

[0034] The display panel 20 further includes at least two connecting lines 50. The control circuit 40 is electrically connected to the target signal line 30 through the connecting lines 50. Specifically, at least a portion of the connecting line 50 extends along the first direction, and the at least two connecting lines 50 are sequentially spaced and distributed along the second direction. One end of the connecting line 50 is electrically connected to the control circuit 40, and the other end is electrically connected to the corresponding target signal line 30. Further, the connecting line 50 and the target signal line 30 correspond one to one, and one connecting line 50 is electrically connected to one target signal line 30.

[0035] In the case where the control circuit is electrically connected to the data line through the fan-out line, the control circuit is located in the extension direction of the data line. Different from this, the control circuit 40 of this embodiment is located on one side of the target signal line 30 in the first direction, and the control circuit 40 is electrically connected to the target signal line 30 through the connecting line 50, and does not need to be electrically connected to the target signal line 30 through the fan-out line. Since the fan-out line is usually located at the frame position of the display panel 20, the display panel 20 of this embodiment omits the fan-out line, which is conducive to reducing its frame size, that is, it is conducive to realizing a narrow frame design.

[0036] It should be noted that the target signal line 30 of this embodiment can be at least one of a data signal line and a power signal line, which is not limited here.

[0037] Please continue reading Figure 2 In one embodiment, the display panel 20 is divided into a display area 21 and a non-display area 22, and the non-display area 22 is disposed around the outer periphery of the display area 21. The display area 21 is the area where the display panel 20 emits light, while the non-display area 22 does not emit light.

[0038] The display area 21 includes a rectangular area 23 and a non-rectangular area 24, and the non-display area 22 is arranged around the rectangular area 23 and the non-rectangular area 24. As the name implies, the rectangular area 23 has a rectangular shape. Similarly, the non-rectangular area 24 has a non-rectangular shape. For example, the display area 21 includes a rectangular area 23 and two non-rectangular areas 24, which are respectively located on both sides of the rectangular area 23 in the second direction, that is, Figure 2 The outer edges of the non-rectangular area 24 at the corners of the display panel 20 are in an arc shape.

[0039] In the prior art, the control circuit is often located in the portion of the non-display area adjacent to the non-rectangular area, and the outer edge of the non-rectangular area bordered by this portion of the non-display area is in a straight line shape. The space in this portion is limited, and each data line needs to be electrically connected to the control circuit through a fan-out line. Different from this, the control circuit 40 of this embodiment is located in the portion of the non-display area 22 adjacent to the rectangular area 23. This portion of the non-display area 22 has enough space to set the control circuit 40 and the connecting line 50, so the fan-out line can be omitted, and the connecting line 50 will not obviously cause the frame size of the display panel 20 to increase. Therefore, the display panel 20 of this embodiment omits the fan-out line, which is conducive to reducing its frame size, that is, it is conducive to realizing a narrow frame design.

[0040] Please also read Figure 3 In an exemplary embodiment, the electrical connection position of the target signal line 30 and the connection line 50 (eg Figure 2 and Figure 3 In the embodiment, the control circuit 40 is located in the non-display area 22 adjacent to the rectangular area 23, and the connection line 50 is not arranged in the non-rectangular area 24, and all the connection lines 50 are located in the rectangular area 23, so that all the target signal lines 30 are electrically connected to the control circuit 40. In this embodiment, since the control circuit 40 is located in the part of the non-display area 22 adjacent to the rectangular area 23, and the connection line 50 is not arranged in the non-rectangular area 24, it is further avoided that the connection line 50 needs to be electrically connected to the control circuit 40 through the fan-out line.

[0041] Furthermore, when the electrical connection position between the target signal line 30 and the connecting line 50 is located in the rectangular area 23, the connecting line 50 extends linearly along the first direction, and each connecting line 50 directly connects the control circuit 40 and the target signal line 30 without being switched through other lines.

[0042] See also Figure 4. In another exemplary embodiment, for a display panel 20 with a higher PPI (Pixels Per Inch, pixel density), other positions of the target signal line 30 except the end may not provide sufficient space to be electrically connected to the connecting line 50. In view of this, the connecting line 50 of this embodiment extends from the rectangular area 23 to the non-rectangular area 24, and is electrically connected to the end of the target signal line 30 in the non-rectangular area 24. The connecting line 50 extends in a bent manner as a whole, but the portion of the connecting line 50 located in the rectangular area 23 extends in a straight line along the first direction. In this way, the electrical connection between the target signal line 30 and the connecting line 50 can be guaranteed, and the risk of the connecting line 50 affecting the connection between the target signal line 30 and other circuit structures can be reduced.

[0043] See also Figure 2 and Figure 5 , Figure 5 2 is a schematic structural diagram of a display panel according to a third embodiment of the present invention.

[0044] In one embodiment, the display panel 20 includes a main body 25 and a bending portion 26. The at least two target signal lines 30 and the at least two connecting lines 50 are located in the main body 25, and the control circuit 40 is located in the bending portion 26. The main body 25 has a light emitting surface 251, and the main body 25 emits light and displays on the light emitting surface 251. The bending portion 26 is also provided with a binding circuit 60, and the control circuit 40 is electrically connected to the binding circuit 60. The binding circuit 60 is used to electrically connect an external circuit structure, so that the control circuit 40 can be electrically connected to the external circuit structure, so that the control circuit 40 can be driven by the external circuit structure to control the signal writing of the target signal line 30. Furthermore, the external circuit structure can be a driver IC (Integrated Circuit Chip, integrated circuit chip), etc., which is not limited here.

[0045] The bending portion 26 is bent relative to the main body 25, and the binding circuit 60 is bent to the side of the main body 25 away from the light emitting surface 251. In this embodiment, the bending portion 26 is bent to further reduce the frame size of the control circuit 40, which is further beneficial to reduce the frame size of the display panel 20 and realize a narrow frame design.

[0046] Please continue reading Figure 2 In one embodiment, the display panel 20 further includes a scan drive circuit 70 and at least two scan signal lines 80, the scan drive circuit 70 is electrically connected to the control circuit 40, and each scan signal line 80 is electrically connected to the scan drive circuit 70. The control circuit 40 is also used to control the writing of signals of the scan signal lines 80, specifically, writing corresponding signals into the scan signal lines 80 through the scan drive circuit 70. Furthermore, the scan drive circuit 70 may be a gate scan drive circuit, such as a GIP (Gate In Panel) or the like.

[0047] In the first direction, the scan driving circuit 70 is located on at least one side of the at least two target signal lines 30, that is, the scan driving circuit 70 is located on the first side and / or the second side of the at least two target signal lines 30. The scan driving circuit 70 and the control circuit 40 may be located on the same side of the at least two target signal lines 30, or the scan driving circuit 70 and the control circuit 40 may be located on different sides of the at least two target signal lines 30.

[0048] The scan signal lines 80 extend along the first direction, and the at least two scan signal lines 80 and the at least two connection lines 50 are sequentially spaced and distributed along the second direction. Figure 2 The situation where the scanning signal lines 80 and the connecting lines 50 are alternately distributed one by one is shown.

[0049] In an exemplary embodiment, the control circuit 40 is located on the first side of the at least two target signal lines 30, and the scan drive circuit 70 is located on the second side of the at least two target signal lines 30, that is, the scan drive circuit 70 is not set on the first side of the at least two target signal lines 30. At this time, the layer structure where the scan signal line 80 is located has sufficient space on the first side to make the connecting line 50, so the connecting line 50 is allowed to be arranged on the same layer as the scan signal line 80, and further allows the connecting line 50 to be made together in the process of making the scan signal line 80, without adding an additional process for making the connecting line 50, which can avoid the increase in process difficulty and cost of the display panel 20 due to the increase in the process.

[0050] Please also refer to Figure 6 The display panel 20 further includes an array layer 27 and a light emitting layer 28. The array layer 27 integrates the circuit structure of the display panel 20 and is used to drive the light emitting layer 28 to emit light for display. Figure 6 The display surface of the display panel 20 is defined by a first direction and a second direction, and the third direction is perpendicular to the display surface formed by the first direction and the second direction.

[0051] The array layer 27 includes a first metal layer 271, a second metal layer 272 and a first interlayer insulating layer 273. The first metal layer 271, the first interlayer insulating layer 273 and the second metal layer 272 are stacked in sequence along the third direction, the connecting line 50 is located in the first metal layer 271, and the target signal line 30 is located in the second metal layer 272. Of course, the scanning signal line 80 is also located in the first metal layer 271. Furthermore, the first metal layer 271 is also used to form a capacitor plate, and the second metal layer 272 is also used to form a source and a drain electrode. The first interlayer insulating layer 273 is formed with a first bridge hole 274, and the connecting line 50 is electrically connected to the target signal line 30 through the conductor in the first bridge hole 274.

[0052] See also Figure 2 , Figure 7 and Figure 8 , Figure 7 is a schematic structural diagram of a fifth embodiment of a display panel of the present invention, Figure 8 2 is a schematic structural diagram of a sixth embodiment of a display panel according to the present invention.

[0053] In another exemplary embodiment, the control circuit 40 is located on the first side of the at least two target signal lines 30, and the scan driving circuit 70 is provided on the first side of the at least two target signal lines 30, or the scan driving circuit 70 is provided on the first side and the second side of the at least two target signal lines 30. In this case, the scan signal line 80 occupies the space on the first side, and the layer structure where the scan signal line 80 is located does not have enough space on the first side to make the connecting line 50, so the connecting line 50 and the scan signal line 80 need to be arranged in layers, which means that this embodiment needs to add a metal layer to make the connecting line 50.

[0054] Specifically, the array layer 27 of the display panel 20 includes a second metal layer 272, a third metal layer 275, and a second interlayer insulating layer 276. The second metal layer 272, the second interlayer insulating layer 276, and the third metal layer 275 are stacked in sequence along the third direction. The connection line 50 is located in the third metal layer 275, and the target signal line 30 is located in the second metal layer 272. The second interlayer insulating layer 276 is formed with a second bridge hole 277, and the connection line 50 is electrically connected to the target signal line 30 through a conductor in the second bridge hole 277.

[0055] Figure 7 The embodiment shows that the scanning driving circuit 70 is provided on both the first side and the second side of the at least two target signal lines 30. The signals written into the scanning signal line 80 by the two scanning driving circuits 70 are consistent. In this embodiment, the driving capability of the scanning driving circuit 70 is improved by the scanning driving circuits 70 on both sides, which is conducive to ensuring the display effect of the display panel 20.

[0056] It should be noted that in the above embodiment, the connection line 50 and the scanning signal line 80 are arranged in the same layer or in layers, which means that in the film layer stacking structure of the display panel 20, the connection line 50 and the scanning signal line 80 belong to the same layer structure, or the connection line 50 and the scanning signal line 80 do not belong to the same layer structure. The connection line 50 and the scanning signal line 80 are arranged in the same layer does not mean that the height of the connection line 50 and the scanning signal line 80 is the same, and the connection line 50 and the scanning signal line 80 are arranged in layers does not mean that the height of the connection line 50 and the scanning signal line 80 is different.

[0057] In summary, the display panel provided by the present invention has a control circuit electrically connected to the target signal line through a connecting line. Specifically, each target signal line is spaced in sequence along the first direction, and the target signal line extends along the second direction. The control circuit is located on at least one side of the target signal line in the first direction. Each connecting line is spaced in sequence along the second direction, and the connecting line extends along the first direction. In this way, the control circuit does not need to be electrically connected to the target signal line through a traditional fan-out line. Since the fan-out line is usually located at the frame position of the display panel, the display panel of the present invention omits the fan-out line, which is beneficial to reducing its frame size, that is, it is beneficial to achieve a narrow frame design.
