In order to increase the aesthetic feeling of the display screen and the appearance of the display device, a display device using a narrow frame has been gradually developed.
At present, the screen of a common display device, such as a monitor, a television, a mobile phone, a tablet computer, etc., is usually regular rectangular. However, with the development of science and technology, the demand of people for the screen of the display device is more and more diversified, and the simple rectangular display device cannot meet the demand of consumers, so that the display devices with various shapes are produced. In the prior art, the shape of the display panel is often designed to be a shape other than a regular rectangle, and such a display panel is generally called a special-shaped display panel. The special-shaped display panel can enable the screen shape of the display device to be designed in a diversified mode, can be applied to products such as an advertisement display screen, an information indication screen, a vehicle-mounted display screen, an intelligent watch, an intelligent bracelet and VR/AR glasses, and is wide in application range. In addition, the shape design of the special-shaped display panel can also avoid some functional modules on the front panel of the display device, such as a camera module, a sensor module or a loudspeaker module, so that the screen occupation ratio of the display device is improved, and the display effect is more prominent.
However, the researchers found that the shapes of the display panels are diversified, which results in a wider frame of the display panel and affects the display quality and the display uniformity of the display panel.

Referring to fig. 1, fig. 2 and fig. 3, fig. 1 is a schematic plan view illustrating a display panel according to an embodiment of the present invention; FIG. 2 is a partial structural view of the region A in FIG. 1; fig. 3 is a schematic cross-sectional view taken along line CC' of fig. 2.
The embodiment provides a display panel, which comprises a display area AA, a non-display area NA arranged around the display area AA;
the display area AA includes at least one notch group 10, the notch group 10 includes a first notch 11 and a second notch 12;
the display area AA further includes: a plurality of data lines 13, a profiled edge 14; the data lines 13 and the shaped edges 14 each extend in the column direction Y;
the profiled edge 14 comprises a first sub-edge 15 and a second sub-edge 16 which are located at different positions, the first sub-edge 15 is recessed towards the inside of the display area AA to form a first notch 11, and the second sub-edge 16 is recessed towards the inside of the display area AA to form a second notch 12;
the non-display area NA includes a first non-display area B1, a second non-display area B2, the first non-display area B1 being disposed adjacent to the first sub-edge 15, the second non-display area B2 being disposed adjacent to the second sub-edge 16;
the data line 13 includes at least two shaped data lines 20, the shaped data lines 20 extending through the first non-display region B1 and the second non-display region B2, the shaped data lines 20 including main body routing parts 21 and different layer routing parts 22, the different layer routing parts 22 and the main body routing parts 21 being located at different conductive layers, respectively;
the different-layer routing parts 22 in any adjacent two of the shaped data lines 20 are located in the first non-display region B1 and the second non-display region B2, respectively.
In order to clearly illustrate the technical solution of the present embodiment, in the irregular data line 20, the main body routing portion 21 is illustrated by a solid line, and the different-layer routing portion 22 is illustrated by a dotted line. Alternatively, the data lines 13 are all disposed on the substrate base 00.
In the display panel provided in this embodiment, a side of the display area AA has a notch. Specifically, the display area AA includes a shaped edge 14, and the shaped edge 14 and the data line 13 extend in the same direction. It should be noted that although the shaped edge 14 has a non-linear shape and a bent or curved structure in a part, the overall extending direction of the shaped edge 14 is still the column direction.
The shaped edge 14 includes a first sub-edge 15 and a second sub-edge 16, the first sub-edge 15 is recessed toward the inside of the display area AA to form a first notch 11, and the second sub-edge 16 is recessed toward the inside of the display area AA to form a second notch 12. The display panel provided by the embodiment is not in a conventional rectangular shape, but in a shape with a notch. When the display panel provided by the embodiment is applied to a display device of a terminal, electronic elements or devices can be integrated in the first notch 11 and the second notch 12, which is beneficial to high integration of the electronic elements or devices and the display panel and is beneficial to realizing the display effect of a full screen.
It should be noted that the number of sub-edges on the shaped edge 14 is not limited in the present invention, and for example, the present invention may further include a first sub-edge 15, a second sub-edge 16, a third sub-edge, and a fourth sub-edge. It should be noted that the number of the notch groups 10 is not specifically limited in the present invention, and the notch groups 10 are at least one group; meanwhile, the number of the notches in the notch group 10 is not particularly limited, for example, the notch group 10 of the present invention includes a first notch 11 and a second notch 12, and the first notch 11 and the second notch 12 are symmetrically disposed, so that the overall aesthetic property can be improved. The notch group 10 of the present invention may further include a first notch 11, a second notch 12, a third notch, and a fourth notch, or include a first notch 11, a second notch 12, a third notch, a fourth notch, a fifth notch, and a sixth notch, which is not described in detail in this embodiment.
Since the display area of the display panel provided in this embodiment has the gap, the shaped data lines 20 need to be wound from the first non-display area B1 and the second non-display area B2. Alternatively, the data lines other than the shaped data line 20 are all regular data lines, and the shape of the regular data lines may be a straight line segment shape.
The routing of the special-shaped data lines 20 in the first non-display area B1 and the second non-display area B2 are routing lines, and as the resolution of the display panel is improved, the number of the routing lines in the first non-display area B1 and the second non-display area B2 is increased, and if the routing lines in the first non-display area B1 and the second non-display area B2 are not specially set, the width of the first non-display area B1 and the width of the second non-display area B2 in the row direction X are increased, which is not beneficial to the narrow border of the display panel.
In the display panel provided in this embodiment, the routing lines in the first non-display region B1 and the second non-display region B2 are specially arranged, specifically, the special-shaped data line 20 is divided into at least two parts, namely, the main body routing part 21 and the different layer routing part 22, and the main body routing part 21 and the different layer routing part 22 are respectively located in different conductive layers, and can be electrically connected to each other through the via hole K.
It is understood that the materials of the different conductive layers are not completely the same, and for the data line 20, the arrangement of the partial routing portions thereof as the different-layer routing portions 22 will cause the equivalent resistance thereof to change. In order to reduce the resistance difference of two adjacent special-shaped data lines, the load of the special-shaped data lines is balanced. For any two adjacent special-shaped data lines 20, the two special-shaped data lines respectively comprise the different-layer routing parts 22, so that the equivalent resistance of the two adjacent special-shaped data lines 20 is balanced, the load of the special-shaped data lines 20 can be balanced, and the display quality of the display panel is improved.
Further, for any two adjacent special-shaped data lines 20, the different-layer routing portions 22 of the two are not adjacently disposed, but are respectively located in the first non-display area B1 and the second non-display area B2.
Specifically, for any adjacent two of the shaped data lines 20A and 20B, the different-layer routing part 22 of the shaped data line 20A and the body routing part 21 of the shaped data line 20B are disposed adjacent to each other in the first non-display area B1. In other words, the windings of any two adjacent special-shaped data lines 20 in the first non-display area are located on different layers, so that the windings of the two adjacent special-shaped data lines in the first non-display area can be arranged more densely without short circuit. Therefore, the width of the first non-display area along the row direction X is reduced, and the narrow frame of the display panel is facilitated.
For any adjacent two of the shaped data lines 20A and 20B, the body routing part 21 of the shaped data line 20A and the different-layer routing part 22 of the shaped data line 20B are disposed adjacent to each other in the second non-display area B2. In other words, the routing lines of any two adjacent odd-shaped data lines 20 in the second non-display area are located on different film layers. Therefore, the winding of two adjacent special-shaped data lines in the second non-display area can be arranged more densely, and the problem of short circuit can not occur. Therefore, the width of the second non-display area along the row direction X is reduced, and the narrow frame of the display panel is facilitated.
In the display panel provided in this embodiment, a side of the display area AA has a notch. Specifically, the shaped edge 14 includes a first sub-edge 15 and a second sub-edge 16, the first sub-edge 15 is recessed toward the inside of the display area AA to form the first notch 11, and the second sub-edge 16 is recessed toward the inside of the display area AA to form the second notch 12. Since the display region has a gap, the shaped data line 20 needs to be wound from the first non-display region B1 and the second non-display region B2, and the shaped data line 20 is divided into at least two parts, i.e., a main body routing part 21 and an opposite layer routing part 22, which are located in different conductive layers. For any two adjacent special-shaped data lines 20, the two special-shaped data lines respectively comprise the different-layer routing parts 22, so that the equivalent resistance of the two adjacent special-shaped data lines 20 is balanced, the load of the special-shaped data lines 20 can be balanced, and the uniformity of display and the display quality of the display panel are improved. Also, the different-layer routing parts 22 in any two adjacent odd-shaped data lines 20 are located in the first non-display region B1 and the second non-display region B2, respectively. The winding of two adjacent special-shaped data lines in the first non-display area and the second non-display area can be arranged more densely, and the problem of short circuit can not occur. Therefore, the width of the first non-display area along the row direction X is reduced, and the narrow frame of the display panel is facilitated.
In some alternative embodiments, referring to fig. 3 and 4, fig. 4 is a schematic cross-sectional view taken along line DD' of fig. 3. In this embodiment, the main body routing portions 21 are all located on the same conductive layer. Specifically, the main body routing portions 21 of the same special-shaped data line 20 are all located on the same conductive layer. For different shaped data lines 20, their body routing portions 21 are also located in the same conductive layer. In this embodiment, the main body routing portions 21 are all disposed on the same conductive layer, so that the structure of the data line can be simplified, and the structural design and manufacturing process of the display panel can be simplified.
In some optional embodiments, please refer to fig. 5, and fig. 5 is a schematic cross-sectional structure diagram of another display panel provided in the embodiments of the present invention.
In the present embodiment, the display panel includes a driving device layer DR including a plurality of transistors ST including a semiconductor portion ST1, a gate electrode ST2, a source electrode ST3, and a drain electrode ST 4;
the body routing portion 21, the source ST3, and the drain ST4 are located in the same conductive layer, and the different-layer routing portion 22 and the gate ST2 are located in the same conductive layer.
The present embodiment provides a display panel in which the driving device layer DR is used to dispose a driving device for driving a light emitting element in the display panel. The driving device layer DR includes a plurality of transistors ST, and in fig. 5, a film structure of the display panel will be described by taking only one transistor ST as an example. It is understood that the display panel provided in this embodiment has a plurality of transistors ST, and the number of transistors ST needs to be set according to the actual requirement of the display panel, which is not particularly limited in this embodiment. Optionally, the driving device layer DR further includes structures such as signal lines, which are not described in detail in this embodiment.
In this embodiment, the body routing portion 21 is provided in the conductive layer where the source ST3 and the drain ST4 are located. Alternatively, the conventional data lines other than the deformed data line 20 are disposed on the conductive layer where the source electrode ST3 and the drain electrode ST4 are located. The different-layer wiring portion 22 and the gate ST2 are provided in the same conductive layer. Generally, the gate ST2, the source ST3, and the drain ST4 are all made of a metal material. For example, the material of the gate ST2 may include: molybdenum, aluminum, materials of the source ST3 and the drain ST4 may include: titanium and aluminum.
In this embodiment, the different-layer routing portion 22 is formed on the conductive layer where the multiplexing gate ST2 is located, and in the process of manufacturing the display panel, the different-layer routing portion 22 and the gate ST2 may be formed at the same time by patterning the same conductive layer, so that the manufacturing process and material of the display panel are saved, and an additional film structure of the display panel is not increased, which is beneficial to the light and thin of the display panel.
In some alternative embodiments, referring to fig. 2 and 6, fig. 6 is a schematic cross-sectional view taken along line EE' in fig. 2. In the first non-display area B1, the distance between two adjacent special-shaped data lines 20 is D1, and D1 is more than or equal to 1 μm; referring to FIG. 2 and FIG. 4, in the second non-display area B2, the distance between two adjacent special-shaped data lines 20 is D2, and D2 is greater than or equal to 1 μm.
In this embodiment, in the first non-display area B1 and the second non-display area B2, the distance between two adjacent special-shaped data lines 20 is not too small, and less than 1 μm may cause large interference of electrical signals between the special-shaped data lines, thereby affecting the accuracy of the electrical signals of the special-shaped data lines and reducing the display quality of the display panel.
In some alternative embodiments, please refer to fig. 7 and 8, fig. 7 is a schematic partial plan view of a display panel according to another embodiment of the present invention, and fig. 8 is a schematic cross-sectional view along line FF' of fig. 7.

Note that the direction perpendicular to the display panel is the Z direction shown in the drawing.
In the display panel provided in this embodiment, in the first non-display region B1, the different-layer routing portions 22 of the special-shaped data lines 20A and the main-body routing portions 21 of the special-shaped data lines 20B are disposed adjacently, that is, any two adjacent routing lines of the special-shaped data lines 20 in the first non-display region are located on different film layers. Therefore, the winding lines of the adjacent two shaped data lines in the first non-display area may be disposed to overlap each other. Therefore, the width of the first non-display area along the row direction X is further reduced, and the narrow frame of the display panel is facilitated.
Similarly, in the second non-display region B2, the different-layer routing part 22 of the shaped data line 20A and the main-body routing part 21 of the shaped data line 20B are disposed adjacently, that is, any two adjacent windings of the shaped data line 20 in the second non-display region are located on different film layers. Therefore, the winding lines of the adjacent two shaped data lines in the second non-display area may be disposed to overlap each other. Therefore, the width of the second non-display area along the row direction X is further reduced, and the narrow frame of the display panel is facilitated.

Referring to fig. 12, when the display device is in a folded state, the bending portion 30 is in a bent state, and the first flat plate portion 31 and the second flat plate portion 32 are overlapped in a direction perpendicular to the first flat plate portion 31.
In the foldable display device, in an unfolded state, that is, a flat state, a user can simultaneously view and use the bent portion 30, the first flat plate portion 31, and the second flat plate portion 32, thereby providing a display experience of a large screen for the user. In the folded state, the bent portion 30 of the display panel is in the bent state. The folded display device is more portable, and is convenient for a user to put into a pocket or a bag for storage.
As can be seen from the above embodiments, the display panel and the display device provided by the present invention at least achieve the following beneficial effects:
the side of the display area is provided with a notch, specifically, the special-shaped edge comprises a first sub-edge and a second sub-edge, the first sub-edge is sunken towards the inside of the display area to form a first notch, and the second sub-edge is sunken towards the inside of the display area to form a second notch. Because the display area has the gap, the special-shaped data line needs to be wound from the first non-display area and the second non-display area, and the special-shaped data line is at least divided into two parts, namely a main body routing part and a different layer routing part which are positioned in different conductive layers. For any two adjacent special-shaped data lines, the two special-shaped data lines respectively comprise different-layer routing parts, so that the equivalent resistance of the two adjacent special-shaped data lines is balanced, the load of the special-shaped data lines can be balanced, and the uniformity of display and the display quality of the display panel are improved. And the different-layer wiring parts in any two adjacent special-shaped data lines are respectively positioned in the first non-display area and the second non-display area. The winding of two adjacent special-shaped data lines in the first non-display area and the second non-display area can be arranged more densely, and the problem of short circuit can not occur. Therefore, the width of the first non-display area along the row direction is reduced, and the narrow frame of the display panel is facilitated.
