In another embodiment, referring to fig. 11a, the scribe line 101 passes through the second frame area 22, the display area 10 and the first frame area 21 in sequence. By cutting along the cutting line 101, a part of the second frame region 22, the display region 10, and the first frame region 21 on the side of the cutting line 101 facing away from the third frame region 23 can be cut off, thereby reducing the frame of the spliced region.

In one embodiment, referring to fig. 12a, the display area 10 has a plurality of display units 110 arranged in rows and columns. A first spacer 1101 is disposed between two adjacent display units 110. A part of the cutting line 101 is positioned in the first spacer region 1101, and the remaining part is positioned in any two of the first frame region 21, the second frame region 22, and the fourth frame region 24. By arranging the cutting lines 101 in the first spacing areas 1101 between two adjacent display units 110, damage to the surrounding display units 110 caused by heat generated by cutting can be effectively avoided, which is beneficial to improving the yield of the display panel 200.

Meanwhile, since the cutting line 101 is positioned within the first spacer 1101, it is possible to prevent the surrounding display unit 110 from being damaged by heat generated at the time of cutting.

In one embodiment, referring to fig. 3 and 13a, the second frame region 22 and/or the fourth frame region 24 are provided with a plurality of functional modules 210 electrically connected to the driving module 231. Each of the functional modules 210 is electrically connected to a corresponding at least one display unit 110. A second partition 2101 is arranged between two adjacent functional modules 210, and the partial cut line 101 is located in the second partition 2101. Specifically, the functional module 210 includes a GOA module and an EOA module, and is mainly used for driving the corresponding display unit 110 according to the driving signal of the driving module 231. Through the second partition 2101 that sets up the cutting line 101 between two adjacent functional modules 210, can effectively avoid the heat that the cutting produced to cause the damage to surrounding functional module 210, be favorable to further improving display panel 200's yield.

In this embodiment, referring to fig. 13a, the second frame area 22 has a plurality of function modules 210, and the fourth frame area 24 does not have the function modules 210. It can be understood that the fourth frame area 24 is not provided with the functional module 210, and even if the fourth frame area 24 of the display panel 200 is cut off, the normal operation of the display panel 200 is not affected, so that the fourth frame area 24 is cut off and is spliced with the adjacent display panel 200, so as to reduce the frame, or the fourth frame area 24 is not cut off, and the width of the fourth frame area 24 is narrowed in the manufacturing process of the display panel 200, so that the fourth frame area 24 is directly spliced with the adjacent display panel 200, and the visual effect is not greatly affected.

In addition, in this embodiment, the fourth frame area 24 is located above the cutting line 101, and the fourth frame area 24 is completely cut off, and in other embodiments, a portion of the fourth frame area 24 and other frame areas may be cut off according to the splicing requirement.

In another embodiment, referring to fig. 13b, the fourth frame area 24 has a plurality of function modules 210, and the second frame area 22 does not have the function modules 210. Similarly, the second frame region 22 is not provided with the functional module 210, and even if the second frame region 22 of the display panel 200 is cut off, the normal operation of the display panel 200 is not affected, so that the second frame region 22 is cut off and spliced with the adjacent display panel 200, thereby reducing the frame, or the second frame region 22 is not cut off, and the width of the second frame region 22 is narrowed in the manufacturing process of the display panel 200, so that the second frame region 22 is directly spliced with the adjacent display panel 200, and the visual effect is not greatly affected.

In another embodiment, referring to fig. 13c, the fourth frame area 24 and the second frame area 22 are provided with a plurality of function modules 210, which is favorable for making the widths of the frames of the second frame area 22 and the fourth frame area 24 uniform, and at the same time, after the display unit 110 and the function module 210 on the top side are cut off along the cutting line 101, the top side is spliced with other display panels 200, which is favorable for making the thicknesses of four sides of the spliced display screen 2000 uniform.

In addition, referring to fig. 3 and 14, when the cutting line 101 is disposed at the boundary between the display area 10 and the first frame area 21, the cutting line 101 has a safe distance from the functional module 210 and the display unit 110, so as to prevent heat from damaging the functional module 210 and the display unit 110.

And, referring to fig. 11c and fig. 15, when the cutting line 101 is disposed in the first and

second spacing regions

1101 and 2101, the cutting line 101 is also spaced apart from the functional module 210 and the display unit 110, so as to prevent heat from damaging the functional module 210 and the display unit 110.

In one embodiment, referring to fig. 13a, a plurality of display units 110 in the same row are disposed in the same row as the corresponding function modules 210, and the first and

second spacing regions

1101 and 2101 where the cutting line 101 passes through are located in the same row. It can be understood that the plurality of functional modules 210 and the plurality of display units 110 are arranged in rows and columns, and each functional module 210 is electrically connected to all display units 110 in the same row to drive the display units 110 in the row to display. By arranging the cutting lines 101 in the first and

second spacing regions

1101, 2101 of the same row, the shape of the cutting lines 101 is relatively simple, which is advantageous for improving the cutting efficiency and reducing the design difficulty of the display panel 200.

In one embodiment, referring to fig. 11d and fig. 13c, signals of the plurality of function modules 210 are sequentially transmitted in a direction from the third frame area 23 to the first frame area 21. It is understood that a plurality of the function modules 210 are electrically connected to the driving module 231 of the third frame region 23. With the above arrangement, the plurality of functional modules 210 adopt a cascade transmission manner from bottom to top (the third frame area 23 faces the first frame area 21), so that after the top display panel 200 is cut off, the plurality of functional modules 210 of the bottom display panel 200 can still transmit the signals of the driving module 231 in sequence, so that the remaining display units 110 can still obtain corresponding signals, thereby displaying normally.

In one embodiment, referring to fig. 13a, the scribe line 101 and the display unit 110 are not overlapped, and the scribe line 101 and the function module 210 are not overlapped. Specifically, when the cutting line 101 is in the display area 10, and the cutting line 101 is disposed only in the first spaced area 1101 between the adjacent display units 110 without passing through the display units 110, likewise, the cutting line 101 is disposed only in the second spaced area 2101 between the adjacent function modules 210 without passing through the function modules 210. During the design of the display panel 200, the routing of the display area 10 and the routing of the frame area 20 are planned in advance according to the position of the cutting line 101, so that the routing around the cutting line 101 is a single-layer routing rather than a multi-layer routing, and short circuit caused by hot melting of the multi-layer routing is avoided. By arranging the cutting line 101 not to overlap with the display unit 110 and the function module 210, display abnormality caused by mistaken cutting of the display unit 110 can be effectively avoided, driving abnormality of the corresponding display unit 110 caused by mistaken cutting of the function module 210 can be effectively avoided, and the cutting reliability can be improved.

In one embodiment, referring to fig. 3, the scribe line 101 is spaced apart from the adjacent trace. By arranging the cutting line 101 to have a distance from the adjacent wires, the heat generated by cutting can be prevented from fusing the surrounding wires or short-circuiting the surrounding wires after the heat is fused, which is beneficial to improving the reliability of the display panel 200. Specifically, the spacing distance is determined according to factors such as a cutting process parameter, a specific structure of an adjacent trace, and the like, wherein the cutting process parameter includes laser output power, power pulse width, focal length, and the specific structure of the adjacent trace includes a fixed structure of the trace, a material of the trace, a panel thickness at a trace position, and the like, so that the spacing distance is determined to be large enough, the cutting heat cannot radiate the adjacent trace or the radiation quantity is lower than a safety standard, and the reliability of the display panel 200 is improved.

In one embodiment, referring to fig. 13a to 13c, the cutting line 101 extends along a straight line or a step. Through setting up cutting line 101 to extend along straight line or ladder, be favorable to realizing the pluralism of concatenation shape, very big improvement user experience.

In one embodiment, referring to fig. 11c and fig. 13c, the display panel 200 includes a first functional area (not shown) having a plurality of functional modules 210, the first functional area is located on a side of the display area 10 opposite to the display surface 90, and the cutting line 101 is not overlapped with the first functional area. By arranging the first functional region provided with the plurality of functional modules 210 on the side of the display region 10 opposite to the display surface 90, the second frame region 22 and the fourth frame region 24 may not need or reduce the number of the functional modules 210, which is beneficial to further reducing the width of the frame of the splicing region, and is beneficial to seamless mutual splicing of the plurality of display panels 200, thereby improving the diversified degree of the splicing shape. Meanwhile, the cutting line 101 is not overlapped with the first functional area, so that the functional modules 210 in the first functional area can be effectively prevented from being cut by mistake.

In one embodiment, referring to fig. 11c and 13c, the display panel 200 includes a second functional area (not shown) having a plurality of functional modules 210, and the second functional area is disposed in the display area 10. Specifically, the second functional region is disposed in the first spacer 1101 between the adjacent display units 110 in the display region 10. When designing the scribe line 101, it is necessary to ensure that the scribe line 101 does not pass through the first spacer 1101 where the functional module 210 driving the remaining display unit 110 is located, and to avoid display abnormality caused by mis-cutting of the functional module 210.
