Referring to fig. 4 and 5, fig. 4 is a schematic plan view of a display panel according to an embodiment of the present invention, and fig. 5 is a schematic partial enlarged view of the display panel shown in fig. 4.
The present invention provides a display panel, comprising: a display area AA and a non-display area BB surrounding the display area; the display area AA includes a first edge 10, the first edge 10 being recessed toward the inside of the display area AA such that the display area AA forms at least one recessed area 20 and at least one protruding area 30 adjacent to the recessed area 20, the protruding area 30 protruding in a direction away from the inside of the display area AA; the non-display area BB includes a fan-out area 11, the fan-out area 11 being adjacent to the first edge 10; the display area AA includes a plurality of signal traces 40 extending along the first direction x, the fan-out area 11 includes a plurality of lead-out lines 41, and the signal traces 40 are electrically connected to the lead-out lines 41; the projection regions 30 and the fan-out regions 11 are arranged in a second direction y, which intersects the first direction x; the display panel comprises at least one connecting line 50, and the connecting line 50 and the signal wires 40 are arranged in different layers; the connection line 50 extends from the display area AA to the fan-out area 11, and the at least one signal trace 40 is electrically connected to the lead-out line 41 through the connection line 50.
In the display panel provided by this embodiment, the display area AA can implement a display function, for example, the display area AA includes a plurality of pixels; the non-display area BB may be used for disposing traces and circuit elements.
The display area AA includes a first edge 10, the first edge 10 may be a broken line segment recessed toward the inside of the display area AA, and the first edge 10 may be a curved line segment recessed toward the inside of the display area AA.
Since the first edge 10 is recessed towards the inside of the display area AA, the display area AA forms a recessed area 20 at the position of the first edge 10, in other words, the display area AA has a "notch" at the position of the first edge 10. Accordingly, at least one side of the recessed region 20 forms a protruding region 30. In the present embodiment, only one of the number of the protruding regions 30 is taken as an example for explanation. Alternatively, referring to fig. 6, fig. 6 is a schematic plan view of another display panel according to an embodiment of the present invention, the number of the protruding areas 30 may be two, and the two protruding areas are respectively located at two sides of the recessed area 20.
The protruding area 30 includes a second edge 301, and the second edge 301 is connected to the first edge 10 and is located on the same side of the display area AA as the first edge 10.
Alternatively, the edge of the display panel may be adaptively adjusted according to the shape of the display area AA. Optionally, the display panel includes a first sub-edge 101, the first sub-edge 101 may be adaptively adjusted according to the shape of the first edge 10, and the first sub-edge 101 may be recessed toward the inside of the display area AA, so that the display panel forms a shape with a "notch".
The display area AA includes a plurality of signal traces 40 extending along the first direction x, and the signal traces 40 are used for transmitting electrical signals. Alternatively, the signal trace 40 may be a gate line or a data line. The signal trace 40 needs to be electrically connected to a signal processing unit in the display panel, or the signal trace 40 needs to be electrically connected to a signal processing unit in the display device where the display panel is located, and the signal processing unit is used for transmitting an electrical signal to the signal trace 40. For example, the signal processing unit may be an Integrated Circuit (IC).
The non-display area BB includes a fan-out area 11, and the fan-out area 11 includes a lead-out 41, and the lead-out 41 is used for electrically connecting the auxiliary signal trace 40 and the signal processing unit. Alternatively, the extending directions of the plurality of lead-out wires 41 may not be completely the same, and the extending directions of the plurality of lead-out wires 41 may be completely different.
Alternatively, the non-display area BB includes the first frame area B1, and the first frame area B1 and the protruding area 30 are adjacent in the first direction x. Specifically, the first frame region B1 and the protruding region 30 share the second edge 301, that is, the first frame region B1 and the protruding region 30 border the second edge 301. The signal traces 40 extending into the protruding area 30 can be routed to the fan-out area 11 through the first frame area B1, and when the number of the signal traces 40 in the protruding area 30 is large, the problem that the corresponding connecting wires 50 are difficult to arrange due to the large number of the connecting wires and affect the original structure in the protruding area 30 can be avoided. In addition, part of the signal traces 40 are electrically connected to the outgoing lines 41 through the connecting lines 50, so that the width D of the first frame area B1 can be reduced, which is beneficial to narrowing the frame of the display panel and improving the display quality.
Optionally, the signal trace 40 includes at least one first signal line 401, and the first signal line 401 extends to the first bezel area B1; the lead-out line 41 includes at least one first lead-out line 411, at least a part of the first signal line 401 and the first lead-out line 411 are electrically connected, and the first lead-out line 411 extends from the first frame area B1 to the fan-out area 11.
In the display panel provided in the present embodiment, at least one connection line 50 is provided in order to reduce the width D of the first bezel area B1. Specifically, the connection lines 50 and the signal traces 40 are disposed in different layers, so that the connection lines 50 may overlap the signal traces in a direction perpendicular to the display panel, that is, the connection lines 50 may cross the signal traces 40 and be partially disposed in the display area AA, so that at least one signal trace 40 is electrically connected to the outgoing lines 41 through the connection lines 50. It is understood that the specific number of the connecting wires 50 can be set according to the specific design requirement of the display panel, and the description of the embodiment is omitted here.
It is understood that the signal traces 40 extending into the protruding region 30 may be electrically connected through the connection lines 50 and the lead-out lines 41, and accordingly, the width D of the portion of the non-display region BB adjacent to the second edge 301 may be zero.
In the display panel provided by this embodiment, the connection lines 50 different from the signal traces 40 are disposed, so that at least one signal trace can be directly electrically connected to the outgoing lines 41 through a portion of the connection lines 50 located in the display area AA. Compared with the prior art, at least one signal wire does not need to be wound to the fan-out area 11 from the non-display area BB, so that the width of part of the non-display area BB can be reduced, the narrow frame of the display panel is facilitated, and the display quality is improved.
In the display panels shown in fig. 4 and 6, for the sake of clarity of the first edge 10, the first edge 10 uses a different linearity from the other edges.
It should be noted that, in the display panels shown in fig. 4, fig. 5, and fig. 6, only the non-display area includes the first frame area as an example for description, and optionally, the display panel provided in the embodiment of the present invention may not be provided with the first frame area. Specifically, referring to fig. 7, fig. 7 is a schematic plan view illustrating another display panel according to an embodiment of the present invention, and fig. 7 is different from fig. 5 in that in the embodiment, the signal traces 40 in the protruding region 30 are all electrically connected to the outgoing lines 41 through the connecting lines 50, so that in the display panel provided in the embodiment, the non-display region does not include the first frame region, which is further beneficial to narrowing the frame of the display panel.
In some optional embodiments, please refer to fig. 8, fig. 8 is a schematic plan view illustrating a display panel according to another embodiment of the present invention, the display panel includes a plurality of gate lines G and a plurality of data lines S; the signal trace 40 is a gate line G or a data line S. In fig. 8, only the signal trace 40 is taken as the data line S for illustration. In other alternative embodiments, the signal trace 40 may be the gate line G.
In some alternative embodiments, please refer to fig. 8 and fig. 9 in combination, fig. 9 is a schematic cross-sectional structure diagram of another display panel provided in the embodiments of the present invention, the display panel provided in this embodiment may be an organic light emitting display panel, specifically, the display area AA includes a plurality of organic light emitting diodes OL, and the organic light emitting diodes OL include an anode OL1, a luminescent material portion OL2, and a cathode OL 3; the material of the connection line 50 and the anode OL1 are the same and disposed in the same layer. Optionally, the display panel further includes a thin film transistor ST, and the thin film transistor ST and the organic light emitting diode OL are electrically connected. Alternatively, the display panel includes a plurality of gate lines G and a plurality of data lines S, the gate lines G and the gate electrodes ST1 of the thin film transistors ST are disposed at the same layer, and the data lines S and the source and drain electrodes ST2 and ST3 of the thin film transistors ST are disposed at the same layer. The signal trace 40 is a gate line G or a data line S, and the signal trace 40 and the connection line 50 are not on the same layer. The anode OL1 is usually made of a material with good conductivity, and the signal trace 40 and the anode OL1 are made of the same material and can have good conductivity. Alternatively, the material of the anode OL1 may include ITO (indium tin oxide) and/or silver. In addition, the structure of the film layer in which the anode OL1 is located is relatively simple, and generally, the film layer in which the anode OL1 is located is not provided with other structures in the display area AA, and in this embodiment, the connection line 50 and the anode OL1 are made of the same material and are provided in the same layer, so that the layout design of the connection line 50 is relatively simple. Alternatively, the connection line 50 and the anode OL1 can be fabricated in the same fabrication process. In addition, in the process of manufacturing the organic light emitting display panel provided in this embodiment, the anode OL1 and the connecting line 50 can be formed simultaneously by patterning the same conductive layer in the same manufacturing process, so that the connecting line 50 is manufactured without adding an additional process, and the connecting line 50 is manufactured without adding an additional material, which is beneficial to improving the manufacturing efficiency of the organic light emitting display panel and reducing the manufacturing cost. In addition, the anode OL1 and the connecting line 50 are disposed in the same layer, and no additional film structure is required, which is beneficial to the light and thin of the display panel.
In some optional embodiments, please refer to fig. 10, fig. 10 is a schematic partial plan view illustrating a display panel according to still another embodiment of the present invention. The signal trace 40 includes a plurality of second signal lines 40b, and the second signal lines 40b extend to the first edge 10; the lead wire 41 includes a plurality of second lead wires 41b, the second signal line 40b and the second lead wires 41b being electrically connected; at least one of the plurality of second outgoing lines 41b is electrically connected to a compensation resistor R, which is located in the fan-out area 11. In this embodiment, after the second signal line 40B extends to the first edge 10, there is no need to electrically connect the lead-out line 41 through the connection line 50, and there is no need to wind wires from the first frame area B1, so the total length of the second signal line 40B and the corresponding second lead-out line 41B is short, and under the condition that the cross-sectional area and the material of the wires of the plurality of signal lines 40 are the same, and the cross-sectional area and the material of the wires of the plurality of lead-out lines 41 are the same, the resistance values of the equivalent resistors of the second signal line 40B and the corresponding second lead-out line 41B are small, and the loss of the electrical signals on the second signal line 40B and the remaining signal lines is different, which may cause non-uniform electrical signals of the signal. Therefore, in this embodiment, the compensation resistor R is disposed in the fan-out region 11, at least one of the second outgoing lines 41b is electrically connected to the compensation resistor R, and the compensation resistor R can increase the equivalent resistance of the second signal line 40b and the corresponding second outgoing line 41b, which is beneficial to improving the uniformity of the electrical signals of the second signal line 40b and the rest of the signal traces and improving the performance of the display panel. It is understood that, when a plurality of compensation resistors R are disposed in the display panel, the resistance values of the plurality of compensation resistors R may not be identical, and may be specifically set according to the resistance value of the corresponding second outgoing line 41 b.
In some optional embodiments, please refer to fig. 11, fig. 11 is a schematic partial plan view illustrating a display panel according to still another embodiment of the present invention. The plurality of signal traces 40 in the protrusion area 30 include a first trace group 40-1 and a second trace group 40-2, and the first trace group 40-1 is located on a side of the second trace group 40-2 away from the fan-out area 11 along the second direction y; the first routing group 40-1 includes at least one signal trace 40, and the second routing group 40-2 includes at least one signal trace 40; the signal traces 40 in the first wire group 40-1 are electrically connected to the outgoing wires 41 through the connection wires 50; the signal traces 40 in the first trace group 40-1 are connected to the first outlet 41.
Optionally, the first routing group 40-1 includes a plurality of adjacent signal traces 40, and the second routing group 40-2 includes a plurality of adjacent first signal lines 401.
In the display panel provided by the embodiment, among the plurality of signal traces 40 in the protruding area 30, a part of the signal traces are electrically connected to the outgoing line 41 through the connecting line 50, and another part of the signal traces are electrically connected to the first outgoing line 411 directly, wherein the first outgoing line 411 extends from the first frame area B1 to the fan-out area 11. In this embodiment, a part of the signal traces are not provided with the corresponding connecting lines 50 and are directly electrically connected to the first outgoing lines 411, and when the number of the signal traces 40 in the protruding area 30 is large and the length of the protruding area 30 along the first direction x is limited, the situation that the number of the corresponding connecting lines 50 is too large, the arrangement is difficult, and the original structure in the protruding area 30 is affected can be avoided. The connection line 50 extends along the second direction y, so that the connection line 50 can be connected to the lead-out line 41 in the shortest length, and the problem that the overlapping area of the connection line 50 and other film layers is large, and a large parasitic capacitance is easily generated is avoided. Further, the first frame area B1 may have a blank area, and the first lead line 411 may not be provided in the blank area. For example, when the first routing group 40-1 includes a plurality of adjacent signal traces 40, there are some areas B11 in the first bezel area B1 where no traces are disposed, and the area B11 is located at a corner of the display panel, optionally, an electronic component (not shown in the figure) may be disposed in the area B11, and may also be used to dispose other traces or circuits of the display panel, which is not limited in this embodiment. In this embodiment, due to the existence of the region B11, the utilization rate of the first frame region B1 of the display panel can be improved. In addition, since the display panel may be fragile at the corners, the area B11 is not provided with traces, which can prevent the reliability of the display panel from being reduced due to the bending and cracking of the corners of the display panel.
In some alternative embodiments, please refer to fig. 12 and 13, fig. 12 is a schematic diagram of a partial planar structure of another display panel according to an embodiment of the present invention, and fig. 13 is a schematic diagram of a circuit structure of a multiplexer.

In the multiplexer 60 shown in fig. 13, M: n is 1: 3, optionally, M: n may be 1: 4. 1: 5. 1: 6, etc., and the present embodiment is not particularly limited thereto. It is to be understood that fig. 13 is only an exemplary illustration of the circuit configuration of the multiplexer and should not be construed as limiting the invention.
In this embodiment, the multiplexer 60 is disposed in the non-display area BB, and since the number of the M input terminals 61 is less than the number of the N output terminals 62, the number of the outgoing lines 41 may be less than the number of the signal traces 40, so that the outgoing lines 41 in the fan-out area 11 and the first frame area B1 may be reduced, which is beneficial to reducing the areas of the fan-out area 11 and the first frame area B1, and is further beneficial to narrowing the frame of the display panel.

In this embodiment, one end of the first connecting line 501 is electrically connected to the input terminal 61 of the multiplexer 60B, and the other end is electrically connected to the outgoing line 41, and since the first connecting line 501 may be partially disposed in the protruding region 30, it is not necessary to wind a wire from the first frame region B1, and thus the area of the first frame region B1 may be further reduced, which is beneficial to narrowing the frame of the display panel.
Optionally, the connection lines 50 include a plurality of first connection lines 501; one first connecting line 501 includes a first wire portion 5011 and a first second wire portion 5012; the first wire part 5011 and the signal wire 40 extend in the same direction, and the first second wire part 5012 and the signal wire 40 extend in the same direction;

of any two first wire portions 5011, the first wire portion 5011 farther from the first edge 10 is longer in length; of any two first second wire portions 5012, the first second wire portion 5012 farther from the first frame area B1 has a longer length.
In this embodiment, the first wire portion 5011 far away from the first edge 10 is longer in length, and the first second wire portion 5012 far away from the first frame area B1 is longer in length, so that a short circuit caused by the mutual intersection of the plurality of first connecting wires 501 can be avoided, and the wire arrangement of the display panel is more reasonable.
