Description

Technical Field

[0001] This invention relates to the field of display technology, and more specifically, to a display panel and a display device. Background Technology

[0002] Today, with the development of the information society, the requirements for display devices that present information are becoming increasingly higher. Therefore, users have a growing demand for flat panel display devices that are small in size, lightweight, and offer excellent display quality.

[0003] In recent years, the use of display devices has become more diversified and widespread. As display devices become thinner and lighter, users have increasingly higher requirements for screen-to-body ratio. Therefore, in the current development of display devices, research aimed at expanding the display area of ​​display devices is becoming increasingly important. Summary of the Invention

[0004] In view of this, the present invention provides a display panel and a display device for improving the screen-to-body ratio of the display device.

[0005] In a first aspect, this application provides a display panel, including a display area and at least one functional device setting area, wherein the display area at least partially surrounds the functional device setting area;

[0006] It also includes multiple data lines extending along a first direction and arranged along a second direction. The data lines include multiple first data lines and second data lines, wherein the second data line includes a first sub-data line and a second sub-data line; along the first direction, the first sub-data line and the second sub-data line in the same second data line are respectively disposed on both sides of the functional device setting area;

[0007] It also includes multiple first routing lines extending along a first direction and multiple second routing lines extending along a second direction;

[0008] This includes at least one end of the second trace being electrically connected to the first trace, and the other end of the second trace being electrically connected to the first data line;

[0009] The second trace includes a first sub-second trace and a second sub-second trace, wherein at least one end of the first sub-second trace and the second sub-second trace are electrically connected to the same first trace, the other end of the first sub-second trace is electrically connected to the first sub-data line, and the other end of the second sub-second trace is electrically connected to the second sub-data line in the same second data line corresponding to the first sub-data line.

[0010] Secondly, this application provides a display device, which includes a display panel.

[0011] Compared with the prior art, the display panel and display device provided by the present invention achieve at least the following beneficial effects:

[0012] This application provides a display panel and display device. By using a first trace and a second trace arranged in the central area of ​​the display area along the direction perpendicular to the extension of the data line, electrical signals are transmitted to the data lines corresponding to the functional device setting area and the data lines on the side of the functional device setting area away from the center of the display panel. This avoids the need for the data lines corresponding to the functional device setting area and the data lines on the side of the functional device setting area away from the center of the display panel to be wound in the R-corner area when electrically connected to the flexible circuit board. In other words, this application achieves the purpose of compressing the bottom bezel width and increasing the screen ratio of the display device by eliminating the winding connection of the R-corner data lines.

[0013] Of course, any product implementing this invention does not necessarily need to achieve all of the technical effects described above at the same time.

[0032] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention.

[0033] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0034] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0035] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0036] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0037] In the current technology, as display devices become thinner and lighter, users have increasingly higher requirements for the screen-to-body ratio of display devices; therefore, in the current development of display devices, research aimed at expanding the display area of ​​display devices is becoming increasingly important.

[0038] In view of this, the present invention provides a display panel and a display device for improving the screen-to-body ratio of the display device.

[0039] Figure 1 The diagram shown is a schematic representation of a display panel provided in an embodiment of this application. Please refer to it. Figure 1 This application provides a display panel 100, including a display area 02 and at least one functional device setting area 10, wherein the display area 02 at least partially surrounds the functional device setting area 10;

[0040] It also includes multiple data lines 20 extending along a first direction and arranged along a second direction. Each data line 20 includes multiple first data lines 21 and second data lines 22. The second data line 22 includes a first sub-data line 221 and a second sub-data line 222. Along the first direction, the first sub-data line 221 and the second sub-data line 222 of the same second data line 22 are respectively located on both sides of the functional device setting area 10.

[0041] It also includes multiple first routing lines 31 extending along a first direction and multiple second routing lines 32 extending along a second direction;

[0042] Among them, at least one end of the second trace 32 is electrically connected to the first trace 31, and the other end of the second trace 32 is electrically connected to the first data line 21;

[0043] The second trace 32 includes a first sub-second trace 321 and a second sub-second trace 322. At least one end of the first sub-second trace 321 and the second sub-second trace 322 are electrically connected to the same first trace 31. The other end of the first sub-second trace 321 is electrically connected to the first sub-data line 221. The other end of the second sub-second trace 322 is electrically connected to the second sub-data line 222 in the same second data line 22 corresponding to the first sub-data line 221.

[0044] Specifically, this application provides a display panel 100, which includes a display area 02 and at least one functional device setting area 10, wherein the functional device setting area 10 is configured to be surrounded by the display area 02; the display panel 100 also includes a plurality of data lines 20, which extend along a first direction and are arranged along a second direction.

[0045] Based on the functional device setting area 10 included in the display panel 100 provided in this application, the data lines 20 are divided into two types, specifically a first data line 21 and a second data line 22. The first data line 21 is a data line 20 in the display panel 100 that extends along a first direction and has no break point. The second data line 22 is a data line 20 that extends along the first direction but has a break point. Specifically, the second data line 22 includes a first sub-data line 221 and a second sub-data line 222. Along the first direction, the first sub-data line 221 and the second sub-data line 222 included in the same second data line 22 can be respectively disposed on both sides of the functional device setting area 10. That is, the difference between the first data line 21 and the second data line 22 is that each second data line 22 is disposed on both sides of the functional device setting area 10 and is composed of two segments (the first sub-data line 221 and the second sub-data line 222).

[0046] Based on the display panel 100 including the functional device setting area 10 surrounded by the display area 02, this application provides an alternative method for designing the wiring structure of the display panel 100 to determine how the data lines 20 set inside receive drive signals. Specifically, multiple combination connection lines of first wirings 31 and second wirings 32 are added to the display panel 100, wherein the first wirings 31 extend along a first direction and the second wirings 32 extend along a second direction.

[0047] In one embodiment, the second trace 32 can be configured to specifically include a first sub-second trace 321 and a second sub-second trace 322. In this case, the first trace 31, which is to be electrically connected to the second trace 32, can be electrically connected to the first sub-second trace 321 and the second sub-second trace 322 at two locations respectively. These two locations are respectively located on both sides of the functional device setting area 10. Furthermore, the other end of the first sub-second trace 321 is electrically connected to the first sub-data line 221 of a second data line 22, and the other end of the second sub-second data line 22 is electrically connected to the second sub-data line 222 of the same second data line 22. That is, the first trace 31 and the second trace 32 transmit electrical signals to the second data line 22 to which they are electrically connected, rather than the second data line 22 directly receiving the corresponding electrical signals. One end of the first trace 31 can be directly connected to the components in the lower frame, thereby enabling the transmission of electrical signals emitted by the components to the first sub-data line 221 via the first trace 31 and the first sub-second trace 321, and the transmission of electrical signals to the second sub-data line 222 via the first trace 31 and the second sub-second trace 322.

[0048] This application reduces the number of data lines 20 that directly receive electrical signals by using the above-mentioned wiring arrangement. At least some of the data lines 20 transmit electrical signals through the added first wiring 31 and second wiring 32. Compared with the data lines 20 that are electrically connected, the added first wiring 31 can change its wiring arrangement position in the display area 02. For example, the first wiring 31 can be set in a position in the middle area of ​​the display area 02 to avoid the wiring space required by the data lines 20 located at the edge when electrically connecting to the components in the lower bezel. This can reduce the lower bezel of the display panel 100 and improve the screen ratio of the display panel 100.

[0049] It should be added that some first data lines 21 located at the edge of display area 02 may also transmit electrical signals through first traces 31 and second traces 32, for example... Figure 1 The first data line 21, located near the left edge of the display area 02, can be electrically connected to components in the lower bezel via the first trace 31 and the second trace 32. This allows electrical signals emitted by the components to be transmitted to the first data line 21 via the first trace 31 and the second trace 32. This also avoids the problem of the data line 20 located at the edge occupying wiring space when electrically connecting to components in the lower bezel, thereby reducing the size of the lower bezel of the display panel 100 and increasing the screen-to-body ratio of the display panel 100.

[0050] Please continue to refer to Figure 1 Optionally, the display area 02 includes a first area A1, a second area A2, and a third area A3 arranged sequentially along the second direction; the second area A2 is located between the first area A1 and the third area A3.

[0051] The second area A2 includes a first sub-second area A21 and a second sub-second area A22. Along the second direction, the first sub-second area A21 is symmetrically arranged on both sides of the second sub-second area A22.

[0052] Multiple data lines 20 in Zone A1 are electrically connected to the second wiring 32;

[0053] The first wiring 31 is located in the first sub-second zone A21, which also includes multiple data lines 20;

[0054] The second sub-zone A22 includes multiple data lines 20;

[0055] The multiple data lines 20 in the third zone A3 are all electrically connected to the second wiring 32.

[0056] Specifically, for ease of describing the technical solution of this application, the display area 02 of the display panel 100 is divided into three areas, namely, a first area A1, a second area A2 and a third area A3 arranged sequentially along the second direction. The second area A2 located between the first area A1 and the third area A3 can be further divided into two first sub-second areas A21 and one second sub-second area A22. Along the second direction, the two first sub-second areas A21 are symmetrically arranged on both sides of the second sub-second area A22.

[0057] This application provides an alternative embodiment in which multiple data lines 20 located in the first zone A1 can all be electrically connected to the second routing line 32, that is, the data lines 20 in the first zone A1 can all transmit electrical signals through the added first routing line 31 and second routing line 32; multiple data lines 20 located in the third zone A3 can also all be electrically connected to the second routing line 32, that is, the data lines 20 in the third zone A3 can all transmit electrical signals through the added first routing line 31 and second routing line 32. Based on this, the first routing line 31 is located in the first sub-second zone A21. Specifically, multiple data lines 20 located in the first zone A1 are electrically connected to the first routing line 31 in the first sub-second zone A21 located on the side of the second sub-second zone A22 near the first zone A1 via the second routing line 32. Similarly, multiple data lines 20 located in the third zone A3 are electrically connected to the first routing line 31 in the first sub-second zone A21 located on the side of the second sub-second zone A22 near the third zone A3 via the second routing line 32. This application is equivalent to leading the data line 20, which is located in the edge area (first area A1 and third area A3) of the display area 02, to the center area (second area A2) of the display area 02 through the second trace 32 and the first trace 31. With this setting, the data line 20, which was originally located in the edge area of ​​the display area 02, can be electrically connected to the components in the lower bezel through the center area of ​​the display area 02. This setting can reduce the trace space required when the data line 20 is electrically connected to the components in the lower bezel, specifically the trace space in the R-corner area corresponding to the lower bezel of the display panel 100. This can reduce the trace width required in the non-display area 01 of the lower bezel, thereby reducing the lower bezel of the display panel 100 and increasing the screen ratio of the display panel 100.

[0058] It should be added that the second area A2 also includes data cable 20. Specifically, the first sub-second area A21 includes both data cable 20 and the first routing cable 31, while the second sub-second area A22 only includes data cable 20 and does not include the first routing cable 31. The second sub-second area A22 may include only one data cable 20 or multiple data cables 20. This application does not make a specific limitation in this regard. Users can adjust the proportion of the second sub-second area A22 in the second area A2 according to the space required to set the first routing cable 31, thereby adaptively adjusting the number of data cables 20 included in the second sub-second area A22.

[0059] It should also be added that when the first sub-second zone A21 is simultaneously provided with a first trace 31 extending along the first direction and a data line 20, it is possible to choose to set one first trace 31 between two adjacent data lines 20; this application is not limited to this, and users can also adjust the number of first traces 31 between two adjacent data lines 20 according to their needs; in addition, it is also possible to choose to set a first trace 31 between some data lines 20 and not between some data lines 20.

[0060] It should also be added that, Figure 1 The illustrations shown are merely for illustrating the various technical solutions provided in this application and do not limit the shape of the display area 02, the number of data lines 20 in the display area 02, the size and shape of the functional device setting area 10, etc. Users can make corresponding adjustments to the internal structure of the display panel 100 according to their needs.

[0061] It should also be added that, Figure 1 A floating first trace 31 may be further provided on the upper side of the first trace 31 shown to uniformly display the reflectivity of the display panel 100 and avoid uneven display of the display panel 100.

[0062] Figure 2 The diagram shown is another schematic diagram of the display panel provided in an embodiment of this application. Please refer to... Figure 2 Optionally, the display area 02 includes a first display area 03 and a second display area 04 disposed along the first direction; the first display area 03 includes a functional device setting area 10;

[0063] In the second display area 04, the number of data lines 20 located in the first area A1 is D1, and the number of first traces 31 located in the first sub-second area A21 between the second sub-second area A22 and the first area A1 is D2, D1:D2=1.

[0064] Specifically, the display panel 100 provided in this application may include a functional device setting area 10. The display area 02 provided in this application may be divided into a first display area 03 and a second display area 04 arranged along a first direction. The functional device setting area 10 may only be set in the first display area 03, that is, there is no functional device setting area 10 in the second display area 04, and it is just a simple screen display area 02.

[0065] At this point, this application provides an alternative embodiment in which the number of data lines 20 located in the first area A1 of the second display area 04 is the same as the number of first traces 31 located in the first sub-second area A21 of the second sub-second area A22 near the first area A1; similarly, in the second display area 04, the number of data lines 20 located in the third area A3 can also be further set to be the same as the number of first traces 31 located in the first sub-second area A21 of the second sub-second area A22 near the third area A3.

[0066] This application achieves this by setting the number of data lines 20 that need to transmit electrical signals through the first trace 31 and the second trace 32 in the second display area 04 to be the same as the number of the first trace 31. This ensures that all data lines 20 located at the edge of the display area 02 along the second direction in the display panel 100 are electrically connected to the components in the lower bezel through the central area of ​​the display area 02 and by means of the first trace 31 and the second trace 32. This arrangement can reduce the trace space required for the data lines 20 to be electrically connected to the components in the lower bezel, specifically the trace space in the R-corner area corresponding to the lower bezel of the display panel 100. This reduces the trace width required in the non-display area 01 of the lower bezel, thereby reducing the lower bezel of the display panel 100 and increasing the screen ratio of the display panel 100.

[0067] Figure 3 The diagram shown is another schematic diagram of the display panel provided in an embodiment of this application. Please refer to... Figure 2 and Figure 3 Optionally, the display area 02 includes a first display area 03 and a second display area 04 disposed along the first direction; the first display area 03 includes a functional device setting area 10;

[0068] In the first display area 03, the number of data lines 20 passing through the functional device setting area 10 is D3, and the number of first traces 31 in the first sub-second area A21 located between the second sub-second area A22 and the first area A1 is D4, where D4:D3≤1.

[0069] Specifically, the display panel 100 provided in this application may include a functional device setting area 10. The display area 02 provided in this application may be divided into a first display area 03 and a second display area 04 arranged along a first direction. The functional device setting area 10 may only be set in the first display area 03, that is, there is no functional device setting area 10 in the second display area 04, and it is just a simple screen display area 02.

[0070] At this point, this application provides an alternative embodiment, such as... Figure 2 As shown, in the first display area 03, the number of data lines 20 that need to pass through the functional device setting area 10 and the number of first traces 31 in the first sub-second area A21 located between the second sub-second area A22 and the first area A1 can be set to the same, both being 3 lines; Figure 3 As shown, the number of data lines 20 that need to pass through the functional device setting area 10 (3 lines) can also be set to be greater than the number of first traces 31 in the first sub-second area A21 located between the second sub-second area A22 and the first area A1 (2 lines). Among them, the data lines 20 that pass through the functional device setting area 10 are the data lines 20 that need to be disconnected in the functional device setting area 10, that is, the second data line 22 mentioned above, which includes the first sub-data line 221 and the second sub-data line 222.

[0071] When the number of data lines 20 that need to pass through the functional device setting area 10 is greater than the number of first traces 31 in the first sub-second area A21 located between the second sub-second area A22 and the first area A1, at least one second data line 22 cannot meet the required electrical signal. In this case, the first sub-data line 221 and the second sub-data line 222 can be connected through other connecting lines so that each second data line 22 can receive the required electrical signal. This application does not specifically limit the setting of the connecting lines for the first sub-data line 221 and the second sub-data line 222 in the electrical connection of the second data line 22. Users can adjust the setting of film layers, wiring methods, etc. according to the actual design of the display panel 100, as long as the connection of the first sub-data line 221 and the second sub-data line 222 can be achieved.

[0072] Please continue to refer to Figure 2 and Figure 3 Optionally, the display area 02 includes a first display area 03 and a second display area 04 disposed along the first direction; the first display area 03 includes a functional device setting area 10;

[0073] In the first display area 03, the number of first traces 31 in the first sub-second area A21, which is located between the second sub-second area A22 and the first area A1, is D4;

[0074] In the second display area 04, the number of first traces 31 in the first sub-second area A21, which is located between the second sub-second area A22 and the first area A1, is D2;

[0075] D4 < D2.

[0076] Specifically, the display panel 100 provided in this application may include a functional device setting area 10. The display area 02 provided in this application may be divided into a first display area 03 and a second display area 04 arranged along a first direction. The functional device setting area 10 may only be set in the first display area 03, that is, there is no functional device setting area 10 in the second display area 04, and it is just a simple screen display area 02.

[0077] This application provides an alternative embodiment in which the number of first traces 31 in the first sub-second area A21 located between the second sub-second area A22 and the first area A1 in the first display area 03 (e.g., Figure 2 The three shown Figure 3 The number of lines shown (2 lines) is less than the number of lines of the first trace 31 in the first sub-second area A21 located between the second sub-second area A22 and the first area A1 in the second display area 04 (e.g., 2 lines). Figure 2 , Figure 3 (As shown in the four examples), that is, the number of first traces 31 in the first display area 03 on the side where the functional device setting area 10 is located can be set to be less than the number of first traces 31 in the second display area 04 on the side where the functional device setting area 10 is not located.

[0078] Specifically, all data lines 20 set in the first zone A1 are electrically connected to the first line 31 through the second line 32 to receive electrical signals. Specifically, in the second display area 04 without the functional device setting area 10, the number of first lines 31 located in a first sub-second zone A21 corresponds one-to-one with the number of data lines 20 in the first zone A1. In the first display area 03 with the functional device setting area 10, some data lines 20 are two-segmented, including the first sub-data line 221 and the second sub-data line 222, while some data lines 20 extend to the second display area 04 in a single segment. The single-segmented data lines 20 (first data lines 21) in the second display area 04 are connected to the first line 31 through the second line 32 to receive electrical signals. The second trace 32 is electrically connected to the first trace 31, which can realize the transmission of electrical signals of the entire first data line 21 across the first display area 03 and the second display area 04. Therefore, only a portion of the second data line 22 exists in the first display area 03. The first sub-data line 221 and the second sub-data line 222, which are arranged on both sides of the functional device setting area 10, need to be electrically connected to the first trace 31. That is, only a portion of the second trace 32 (second data line 22) needs to be correspondingly provided with the first trace 31 in both the first display area 03 and the second display area 04.

[0079] For the reasons mentioned above, this application sets the number of first traces 31 in the first display area 03 to be less than the number of first traces 31 in the second display area 04. This can satisfy the transmission of electrical signals required by the data line 20 in the first area A1, and also avoid the problem of excessively long extension length of each first trace 31. This reduces the complexity of wiring in the display panel 100, reduces the manufacturing cost of the display panel 100, and ensures the normal operation of the display panel 100.

[0080] Please refer to Figure 2 Optionally, the width of the first region A1 along the second direction is W1, where W1 is the distance between the edge of the first region A1 away from the second region A2 and the first trace 31 with the largest distance between the first trace 31 in the first sub-second region A21 located between the second sub-second region A22 and the first region A22; the maximum distance between the edge of the first region A1 away from the second region A2 and the edge of the functional device setting area 10 near the second sub-second region A22 is W2.

[0081] When W2 < W1, the first sub-data line 221 and the second sub-data line 222 of each second data line 22 are electrically connected to the same first trace 31.

[0082] Specifically, this is equivalent to one side of display area 02 (such as...) Figure 2 Taking the right edge as an example, the distance between the first first trace 31 near the edge and the edge is W1; when a functional device setting area 10 is provided in the display panel 100, the maximum distance from the edge to the edge of the adjacent functional device setting area 10 near the center of the display area 02 is W2; when W2 < W1, that is, the functional device setting area 10 is located between the first first trace 31 near the edge and the edge.

[0083] Based on the above-described structural arrangement of the display panel 100, this application provides an optional arrangement in which all second data lines 22 in the functional device setting area 10, including the first sub-data line 221 and the second sub-data line 222, can be electrically connected to the same first trace 31. That is, along the first direction, each second data line 22, including the first sub-data line 221 and the second sub-data line 222, is electrically connected to the corresponding first sub-second trace 321 and the second sub-second trace 322, and then electrically connected to a first trace 31. This allows each second data line 22 in the functional device setting area 10 to receive the electrical signal transmitted through the same first trace 31, which is beneficial for making the display effect of the display panel 100 more stable and better.

[0084] Please refer to Figure 3 Optionally, the width of the first region A1 along the second direction is W1, where W1 is the distance between the edge of the first region A1 away from the second region A2 and the first trace 31 with the largest distance between the first trace 31 in the first sub-second region A21 located between the second sub-second region A22 and the first region A22; the maximum distance between the edge of the first region A1 away from the second region A2 and the edge of the functional device setting area 10 near the second sub-second region A22 is W2.

[0085] When W2 > W1, the first sub-data line 221 and the second sub-data line 222 of at least one second data line 22 located in the first zone A1 are electrically connected to the same first trace 31; the first sub-data line 221 and the second sub-data line 222 of at least one second data line 22 are electrically connected through the first connecting line 41 and the second connecting line 42.

[0086] The first connecting line 41 extends along the first direction, and the second connecting line 42 extends along the second direction.

[0087] Specifically, this is equivalent to one side of display area 02 (such as...) Figure 2 Taking the right edge as an example, the distance between the first first trace 31 near the edge and the edge is W1; when a functional device setting area 10 is provided in the display panel 100, the maximum distance from the edge to the edge of the adjacent functional device setting area 10 near the center of the display area 02 is W2; when W2 > W1, that is, when the first first trace 31 near the edge extends along the first direction towards the functional device setting area 10, it will pass through the functional device setting area 10; this application provides an optional The configuration can be configured such that the specific routing of some second data lines 22 is such that both the first sub-data line 221 and the second sub-data line 222 can be electrically connected to the same first routing line 31; the specific routing of other second data lines 22 can be such that the first sub-data line 221 and the second sub-data line 222 are electrically connected through other routing, specifically, each second data line 22 can be electrically connected by adding one first connecting line 41 and two second connecting lines 42, wherein one second connecting line 42 ( Figure 3 One end of the second connecting line 42 located below the functional device setting area 10 is electrically connected to the first end of the first connecting line 41, and the other end is electrically connected to the first sub-data line 221. Another second connecting line 42 ( Figure 3One end of the second connecting line 42 located on the upper side of the functional device setting area 10 is electrically connected to the second end of the first connecting line 41, and the other end is electrically connected to the second sub-data line 222. This arrangement enables the electrical connection of the first sub-data line 221 and the second sub-data line 222 on the same second data line 22 located on both sides of the functional device setting area 10, so as to ensure the stability of the electrical signal received by each second data line 22, thereby making the display effect of the display panel 100 more stable and better.

[0088] Figure 4 The diagram shown is another schematic diagram of the display panel provided in an embodiment of this application. Please refer to... Figure 3 and Figure 4 Optionally, along the first direction, a first spacing H1 is included between the first sub-data line 221 and the second sub-data line 222 electrically connected by the first connecting line 41 and the second connecting line 42, and a second spacing H2 is included between the first sub-secondary line 321 and the second sub-secondary line 322 electrically connected to the same first trace 31, where H2 > H1.

[0089] Specifically, when W2 > W1, and when at least one second data line 22 is electrically connected through the aforementioned first connecting line 41 and second connecting line 42, and simultaneously there are second data lines 22 electrically connected to the same first connecting line 31 through two second traces 32, this application provides an optional configuration method in which the data lines 20 electrically connected through the first connecting line 41 and second connecting line 42 are configured along the second direction, located in the area that needs to pass through the functional device setting area 10, and close to at least one edge of the functional device setting area 10; that is, the data lines 20 that pass through the functional device setting area 10 and are close to the edge of the functional device setting area 10 have a relatively small discontinuity distance, which can be specifically H1, while the data lines 20 that pass through the central area and the area near the central area of ​​the functional device setting area 10 have a relatively large discontinuity distance, which can be specifically H2.

[0090] This configuration, by adding the first trace 31, the second trace 32, and the first connecting line 41 and the second connecting line 42, ensures that all data lines 20 located along the second direction in the display panel 100 at the edge of the display area 02 are electrically connected to the components in the lower bezel via the central area of ​​the display area 02 and the first trace 31 and the second trace 32. This configuration reduces the trace space required for the data lines 20 to be electrically connected to the components in the lower bezel, specifically the trace space in the R-corner area corresponding to the lower bezel of the display panel 100. This reduces the trace width required in the non-display area 01 of the lower bezel, thereby reducing the lower bezel of the display panel 100 and increasing the screen-to-body ratio of the display panel 100.

[0091] Please refer to Figure 3 Optionally, the second data line 22, which is electrically connected via the first connecting line 41 and the second connecting line 42, is located only in the second zone A2.

[0092] Specifically, when W2 > W1, and when at least one second data line 22 is electrically connected through the first connecting line 41 and the second connecting line 42, and simultaneously there are two second data lines 22 electrically connected to the same first connecting line 31 through two second traces 32, this application provides an optional configuration method in which the second data line 22 electrically connected through the first connecting line 41 and the second connecting line 42 is located only on the side of the first trace 31 closest to the edge of the display area 02 adjacent to the functional device setting area 10, near the center of the display area 02. That is, the second data line 22 electrically connected through the first connecting line 41 and the second connecting line 42 is located only on the side of the functional device setting area 10 near the center of the display area 02.

[0093] This configuration enables electrical connection between the first sub-data line 221 and the second sub-data line 222 included in the second data line 22. It also ensures that the added first trace 31, second trace 32, first connecting line 41, and second connecting line 42 are all located in the second area A2 in the second direction. During the manufacturing process, the printing of the added traces will be more concentrated in the display area 02 of the display panel 100, reducing the complexity of the display panel manufacturing.

[0094] Please refer to Figure 4 Optionally, for the second data line 22 electrically connected by the first connecting line 41 and the second connecting line 42, along the second direction, the second data line 22 electrically connected to the first connecting line 41 and the second connecting line 42 is disposed on both sides of the second data line 22 electrically connected to the same first trace 31.

[0095] Specifically, when W2 > W1, and when at least one second data line 22 is electrically connected through the aforementioned first connecting line 41 and second connecting line 42, and simultaneously there are second data lines 22 electrically connected to the same first connecting line 31 through two second traces 32, this application provides an optional configuration method whereby, in addition to the first trace 31 located closest to the edge of the display area 02 adjacent to the functional device setting area 10 and near the center of the display area 02, the second data line 22 electrically connected through the first connecting line 41 and second connecting line 42 may also pass through the center point of the functional device setting area 10 away from the center point of the display area 02; that is, in the second direction, on both sides of the center point area in the functional device setting area 10, there will be second data lines 22 that need to be electrically connected through the first connecting line 41 and second connecting line 42.

[0096] This application separates the second data line 22, which is electrically connected to the first connecting line 41 and the second connecting line 42, onto both sides of the second data line 22 electrically connected to the same first trace 31. This makes the spacing H2 between the first sub-data line 221 and the second sub-data line 222 included in the second data line 22 electrically connected to the same first trace 31 larger than the spacing H1 between the first sub-data line 221 and the second sub-data line 222 included in the second data line 22 electrically connected to the first connecting line 41 and the second connecting line 42. This makes the spacing between the first sub-data line 221 and the second sub-data line 222 smaller. The lines 222 are electrically connected via a first connecting line 41 and a second connecting line 42. Therefore, the electrical signals received by the second data line 22 are transmitted sequentially from bottom to top. The second data lines 22 electrically connected to the same first trace 31 transmit electrical signals to the first sub-data line 221 via the first sub-second trace 321. At the same time, the first trace 31 also transmits electrical signals upwards, thereby shortening the time difference between the first sub-data line 221 and the second sub-data line 222 included in the second data line 22 electrically connected to the same first trace 31 receiving electrical signals.

[0097] That is, with the above configuration, when the distance between the first sub-data line 221 and the second sub-data line 222 included in the second data line 22 is relatively small, the electrical signal can be transmitted sequentially from bottom to top; when the distance is relatively large, the electrical signal is transmitted upwards at the same time as it is transmitted to the first sub-data line 221, so as to transmit to the second data line 222 as soon as possible. With this configuration, the data lines 20 located on both sides of the functional device setting area 10 can complete the transmission of electrical signals in almost the same time or even the same time, so as to improve the display stability of the display panel 100; and can shorten the length of all the traces that need to be added along the first direction to a certain extent, reduce the complexity of the internal wiring of the display panel 100, and simplify the manufacturing process of the display panel 100.

[0098] Please refer to Figure 3 and Figure 4 Optionally, the first connecting line 41 is manufactured in the same layer and with the same process as the data line 20, while the second connecting line 42 is manufactured in a different layer than the data line 20.

[0099] Specifically, this application provides an alternative embodiment in which, since both the first connecting line 41 and the data line 20 extend along the first direction, in order to avoid the functional device setting area 10 and to avoid the influence of electrical signals generated by electrical connections to other data lines 20, the first connecting line 41 will not occupy the area in the display area 02 where the data lines 20 are originally set. For example, the first connecting line 41 can be set between two adjacent data lines 20. Based on this, the first connecting line 41 and the data line 20 can be optionally set to be manufactured in the same layer and with the same process, avoiding the increase in the manufacturing process of the display panel 100 due to the addition of the first connecting line 41, and at the same time avoiding the increase in the manufacturing cost of the display panel 100. Furthermore, since the second connecting line 42 extends along the second direction, the extension direction of the second connecting line 42 intersects with the extension direction of the data line 20, thus avoiding contact between the second connecting line 42 and the data line 20 and preventing the second connecting line 42 from affecting the electrical signal of the data line 20. The second connecting line 42 and the data line 20 can be fabricated in different layers, that is, the metal layer where the second connecting line 42 is located and the metal layer where the data line 20 is located are insulated by an insulating layer, thereby ensuring the stability of the electrical signals received by each signal in the display panel 100 and improving the display effect of the display panel 100.

[0100] It should be added that this application does not limit the first connecting line 41 to be fabricated on the same layer as the data line 20. If the number of film layers and space allow, the first connecting line 41, the second connecting line 42, and the data line 20 can also be set on different layers. In addition, this application does not limit all data lines 20 to be located in the same metal layer. Similarly, the first connecting line 41 included in the display panel 100 can also be distributed in different metal layers, and the second connecting line 42 included in the display panel 100 can also be distributed in different metal layers. That is, the film layers corresponding to various types of traces in the display panel 100 can be adjusted by the user according to the actual product, and this application does not make specific limitations in this regard.

[0101] Figure 5 The diagram shown is another schematic diagram of the display panel provided in an embodiment of this application. Figure 6 The diagram shown is another schematic diagram of the display panel provided in an embodiment of this application. Please refer to... Figures 3-6 Optionally, the display panel 100 includes a non-display area 01, which at least partially surrounds the display area 02;

[0102] At least one first connection line 41 is located in the non-display area 01.

[0103] Specifically, the display panel 100 provided in this application, in addition to including a display area 02, may further include a non-display area 01. The non-display area 01 may be configured to exist around the display area 02. When a first connecting line 41 and a second connecting line 42 are provided in the display panel 100, this application provides at least three selectable configuration methods for the area where the first connecting line 41 is configured. One of these is, as shown in the example... Figure 3 , Figure 4 As shown, all first connecting lines 41 are located within display area 02; secondly, as... Figure 5 As shown, some of the first connecting lines 41 are located within the display area 02, and some of the first connecting lines 41 are located within the non-display area 01. Figure 5 The first connecting line 41 shown in the figure is located in the non-display area 01 on the left side of the figure; the third is, as shown in the figure. Figure 6 As shown, all first connection lines 41 are located within the non-display area 01.

[0104] When the first connecting line 41 added to the display panel 100 is at least partially set in the non-display area 01, the space occupied by the first connecting line 41 in the display area 02 can be reduced or avoided, and the drawbacks that the added wiring in the display area 02 may cause to the display effect can also be avoided.

[0105] It should be added that users can choose the appropriate method for the three first connection line 41 configurations provided in this application according to the actual product design requirements, and this application does not impose any specific limitations on this.

[0106] It should also be added that, Figure 6 The two first connecting lines 41 shown are respectively set in the non-display areas 01 on the left and right sides. This is only one optional embodiment provided by this application. Depending on the actual setting structure of the display panel 100, multiple first connecting lines 41 can be set in the non-display area 01 on the left or in the non-display area 01 on the right. This application does not make any specific limitation in this regard.

[0107] Figure 7 The diagram shown is another schematic diagram of the display panel provided in an embodiment of this application. Please refer to... Figure 7 Optionally, the functional device setting area 10 includes a light-transmitting area 11 and a first non-display area 12 surrounding the light-transmitting area 11;

[0108] At least a portion of the second sub-second wiring 322 is located in the first non-display area 12, and the second sub-second wiring 322 is located on the side of the light-transmitting area 11 away from the first sub-second wiring 321.

[0109] Specifically, the functional device setting area 10 provided in this application can be used to set up cameras, photosensitive devices, etc. Therefore, there will be a light-transmitting part in the functional device setting area 10, and there will also be some component setting areas to assist in the use of related devices. Specifically, the functional device setting area 10 can be divided into a light-transmitting area 11 and a first non-display area 12. The first non-display area 12 can be set to exist around the light-transmitting area 11.

[0110] At this time, this application also provides an optional setting method, in the first direction, taking the non-display area 01 (lower non-display area) near the component that outputs electrical signals to the data line 20 as an example, the second trace 32 of the light-transmitting area 11 of the functional device setting area 10 near the non-display area 01 (lower non-display area) is specifically the first sub-second trace 321, and the second trace 32 of the light-transmitting area 11 of the functional device setting area 10 away from the non-display area 01 is specifically the second sub-second trace 322; at this time, at least part of the second sub-second trace 322 can be set to be routed through the first non-display area 12 and then electrically connected to the corresponding second data line 22; such a setting reduces the area occupied by the added second sub-second trace 322 in the display area 02, can avoid the interference of the added trace to other traces in the display panel 100, and is conducive to ensuring the stability and good performance of the display panel 100.

[0111] It should be added that, taking the current mainstream display panel including the functional device setting area as an example, the number of traces in the corresponding left first non-display area and upper first non-display area in the functional device setting area is relatively small, and there is still space to add other traces. Therefore, this application provides an embodiment as follows: Figure 7 As shown, the second sub-second trace 322 can be routed through the upper side of the first non-display area 12, which can avoid expanding the space of the first non-display area 12 and also avoid the impact of space compression on other components in the area, thus ensuring the yield of the entire display panel 100.

[0112] Figure 8 The diagram shown is another schematic diagram of the display panel provided in an embodiment of this application. Please refer to... Figure 8 Optionally, the functional device setting area 10 includes a light-transmitting area 11 and a first non-display area 12 surrounding the light-transmitting area 11;

[0113] At least a portion of the second sub-second wiring 322 is located in the first non-display area 12, and the second sub-second wiring 322 is located in the light-transmitting area 11 on the side close to the first sub-second wiring 321.

[0114] Specifically, the functional device setting area 10 provided in this application can be used to set up cameras, photosensitive devices, etc. Therefore, there will be a light-transmitting part in the functional device setting area 10, and there will also be some component setting areas to assist in the use of related devices. Specifically, the functional device setting area 10 can be divided into a light-transmitting area 11 and a first non-display area 12. The first non-display area 12 can be set to exist around the light-transmitting area 11.

[0115] At this time, this application also provides an optional setting method, which is to take the non-display area 01 (lower non-display area) near the component that outputs electrical signals to the data line 20 as an example along the first direction. The second trace 32 of the light-transmitting area 11 of the functional device setting area 10 near the non-display area 01 is specifically the first sub-second trace 321. This application also provides an optional setting method, in which at least part of the second sub-second trace 322 is routed through the first non-display area 12 and then electrically connected to the corresponding second data line 22. At this time, at least part of the second sub-second trace 322 can be set between the light-transmitting area 11 and the first sub-second trace 321. This setting reduces the area occupied by the added second sub-second trace 322 in the display area 02, and can avoid interference of the added trace to other traces in the display panel 100, which is conducive to ensuring the stability and good performance of the display panel 100.

[0116] It should be added that, taking the current mainstream display panel including the functional device setting area as an example, the number of traces in the corresponding left first non-display area and upper first non-display area in the functional device setting area is relatively small. Therefore, this application provides an embodiment as follows: Figure 8 As shown, the second sub-second trace 322 can be routed through the left side of the first non-display area 12, which can avoid expanding the space of the first non-display area 12 and also avoid the impact of space compression on other components in the area, thus ensuring the yield of the entire display panel 100.

[0117] Please continue to refer to Figure 8 Optionally, the first non-display area 12 includes a first sub-non-display area 121 and a second sub-non-display area 122. Along the second direction, the first sub-non-display area 121 is located on the side of the second sub-non-display area 122 away from the second sub-second area A22.

[0118] The number of second sub-second routing lines 322 in the first sub-non-display area 121 is K1, and the number of second sub-second routing lines 322 in the second sub-non-display area 122 is K2, where K1 < K2.

[0119] Specifically, the functional device setting area 10 provided in this application can be used to set up cameras, photosensitive devices, etc. Therefore, there will be a light-transmitting part in the functional device setting area 10, and there will also be some component setting areas to assist in the use of related devices. Specifically, the functional device setting area 10 can be divided into a light-transmitting area 11 and a first non-display area 12. The first non-display area 12 can be set to exist around the light-transmitting area 11.

[0120] This application provides an alternative embodiment in which the first non-display area 12 includes a first sub-non-display area 121 and a second sub-non-display area 122 located on both sides of the light-transmitting area 11 along a second direction, wherein the first sub-non-display area 121 is located on the side of the second sub-non-display area 122 away from the center point of the display panel 100. Taking the currently mainstream display panel including a functional device setting area as an example, the number of traces in the corresponding left first non-display area and upper first non-display area in the functional device setting area is relatively small. Therefore, this application provides an embodiment in which the number of traces in the left first non-display area 12 is less than the number of traces in the right first non-display area 12. Applying this application, when at least a portion of the second sub-second trace 322 is located in the first non-display area 12, and the second sub-second trace 322 is located on the side of the light-transmitting area 11 closer to the first sub-second trace 321, the number of second sub-second traces 322 passing through the first sub-non-display area 121 can be set to be less than the number of second sub-second traces 322 in the second non-display area 122.

[0121] With the above settings, the second sub-second trace 322 is routed through the left and right sides of the first non-display area 12, which avoids expanding the space of the first non-display area 12 and also avoids the impact of space compression on other components in the area, thus ensuring the overall yield of the display panel 100.

[0122] Figure 9 The diagram shown is another schematic diagram of the display panel provided in an embodiment of this application. Please refer to... Figure 2 and Figure 9 Optionally, along the second direction, the first routing line 31 located in the first sub-second area A21 includes a first sub-first routing line 311 and a second sub-first routing line 312. The first sub-first routing line 311 is located on the side of the second sub-first routing line 312 away from the second sub-second area A22. The length of the first sub-first routing line 311 along the first direction is L1, and the length of the second sub-first routing line 312 along the first direction is L2, where L1 < L2 or L1 > L2.

[0123] Specifically, along the second direction, the first trace 31 located in the first sub-second area A21 may include a first sub-first trace 311 and a second sub-first trace 312, wherein the first sub-first trace 311 is located on the side of the second sub-second area A22 away from the center of the display area 02. This application provides at least two selectable configuration methods, one of which is as follows: Figure 2 As shown, along the first direction, the length of the first sub-first trace 311 is less than the length of the second sub-first trace 312; secondly, as... Figure 9 As shown, along the first direction, the length of the first sub-first trace 311 is greater than the length of the second sub-first trace 312.

[0124] In other words, along the direction from the first zone A1 to the second sub-zone A22, and / or along the direction from the third zone A3 to the second sub-zone A22, the length of the first trace 31 along the first direction can be arranged in an increased manner (e.g., Figure 2 As shown), it can also be presented as a reduced setting (such as...). Figure 9 (As shown). By setting the lengths of the adjacent first traces 31 to be different, the second traces 32 that are electrically connected to them are prevented from contacting each other on the same layer, thus avoiding mutual interference during the transmission of electrical signals. This helps to ensure the stability and quality of the display panel 100.

[0125] Figure 10 The diagram shown is another schematic diagram of the display panel provided in an embodiment of this application. Please refer to... Figure 10 Optionally, the display panel 100 includes a non-display area 01, which at least partially surrounds the display area 02;

[0126] The second sub-line 322 is located in the non-display area 01.

[0127] Specifically, this application also provides an optional setting method in which, along the first direction, taking the non-display area 01 near the component that outputs electrical signals to the data line 20 as an example, the second trace 32 of the light-transmitting area 11 of the functional device setting area 10 near the non-display area 01 can be specifically set as a first sub-second trace 321, and the second trace 32 of the light-transmitting area 11 of the functional device setting area 10 away from the non-display area 01 can be specifically set as a second sub-second trace 322.

[0128] The non-display area 01 of the display panel 100 can be set around the display area 02. In this case, at least one second sub-second trace 322 can be set in the non-display area 01 on the side of the functional device setting area 10 away from the non-display area 01 where the component is located. Alternatively, if there is enough space in the non-display area 01, all the second sub-second traces 322 can be set in the non-display area 01 on the side of the functional device setting area 10 away from the non-display area 01 where the component is located. This setting reduces the area occupied by the added second sub-second traces 322 in the display area 02, avoids interference of the added traces with other traces in the display panel 100, and helps to ensure the stability and good performance of the display of the screen of the display panel 100.

[0129] Figure 11 The diagram shown is another schematic diagram of the display panel provided in an embodiment of this application. Please refer to... Figure 11 Optionally, the display panel 100 includes at least two functional device setting areas 10;

[0130] The first routing line 31 includes a first sub-first routing line 311 and a second sub-first routing line 312;

[0131] It includes at least one second data line 22, wherein the first sub-data line 221 is electrically connected to the first sub-first data line 311 via the first sub-second data line 321, and the second sub-data line 222 is electrically connected to the first sub-first data line 311 via the second sub-second data line 322, the second sub-first data line 312, and the first sub-second data line 321.

[0132] The first sub-first trace 311 is located on the side of the second sub-first trace 312 that is close to the functional device setting area 10.

[0133] Specifically, each display panel 100 may include not only one functional device setting area 10, but may also include two or more functional device setting areas 10; here, this application provides an optional embodiment, such as... Figure 11As shown, the display panel 100 includes two functional device setting areas 10. The first trace 31 extending along the first direction includes a first sub-first trace 311 and a second sub-first trace 312. The second sub-first trace 312 does not overlap with the extending direction of the first sub-first trace 311. At least one second data line 22 is included, whose first sub-data line 221 is electrically connected to the first sub-first trace 311 after passing through the first sub-second trace 321. The second sub-data line 222 included in this second data line 22 is electrically connected to the first sub-first trace 311 via the second sub-second trace 322, the second sub-first trace 312, and the aforementioned first sub-second trace 321. That is, at least one second data line 22, including both its first sub-data line 221 and second sub-data line 222, needs to pass through the same first sub-first trace 311 and the same first sub-second trace 321 during the reception of electrical signals.

[0134] Furthermore, if a functional device setting area 10 is located relatively close to the center of the display panel 100, then the data line 20 passing through the functional device setting area 10 can be directly connected to the component that outputs the corresponding electrical signal in the non-display area 01. The first connecting line 41 and the second connecting line 42 are used to realize the electrical connection of the data line 20 that is disconnected in the functional device setting area 10, thereby realizing the electrical connection of the data lines 20 set on both sides of the functional device setting area 10 along the first direction and realizing the normal transmission of their corresponding electrical signals.

[0135] Please continue to refer to Figure 11 Optionally, based on the above-mentioned display panel 100 including two functional device setting areas 10, this application further provides an optional embodiment in which the display area 02 includes a first display area 03 and a second display area 04 disposed along a first direction; the first display area 03 includes the functional device setting area 10;

[0136] In the first display area 03, the number of data lines 20 passing through the functional device setting area 10 is D5, and the number of the second sub-first traces 312 is D6, where D5:D6 = 1.

[0137] Specifically, in a display panel 100 with two functional device setting areas 10, the number of data lines 20 passing through the functional device setting area 10 in the first display area 03 can be set to be equal to the number of second sub-first traces 312. That is, the second sub-first traces 312 are set to provide electrical signals to the second sub-data lines 222 passing through the functional device setting area 10. Therefore, as long as the number of data lines 20 passing through the functional device setting area 10 is equal to the number of second sub-first traces 312, the normal transmission of electrical signals of each data line 20 in the first display area 03 of the display panel 100 can be satisfied, avoiding the addition of too many traces in the display area 02. This can avoid interference from additional traces to other traces and help ensure the stability and good performance of the display panel 100.

[0138] Please continue to refer to Figure 11 Optionally, the first trace 31 is manufactured on the same layer and with the same process as the data cable 20, while the second trace 32 is manufactured on a different layer than the data cable 20.

[0139] Specifically, this application provides an alternative embodiment in which, since both the first trace 31 and the data line 20 extend along the first direction, in order to avoid the functional device setting area 10 and to avoid the influence of electrical signals generated by electrical connections to other data lines 20, the first trace 31 will not occupy the area in the display area 02 where the data line 20 is originally located. For example, the first trace 31 can be set between two adjacent data lines 20. Based on this, the first trace 31 and the data line 20 can be optionally set to be manufactured in the same layer and with the same process, avoiding the increase in the process of the display panel 100 due to the addition of the first trace 31, and at the same time avoiding the increase in the manufacturing cost of the display panel 100. Furthermore, since the second trace 32 extends along the second direction, the extension direction of the second trace 32 intersects with the extension direction of the data line 20. In order to avoid the second trace 32 from contacting the data line 20 and to avoid the influence of the second trace 32 on the electrical signal of the data line 20, the second trace 32 and the data line 20 can be fabricated in different layers. That is, the metal layer where the second trace 32 is located and the metal layer where the data line 20 is located are insulated by an insulating layer, thereby ensuring the stability of the electrical signals received by each signal in the display panel 100 and improving the display effect of the display panel 100.

[0140] It should be added that this application does not limit the first trace 31 to be fabricated on the same layer as the data line 20. If the number of film layers and space allow, the first trace 31, the second trace 32, and the data line 20 can also be set on different layers. In addition, this application does not limit all data lines 20 to be located in the same metal layer. Similarly, the first trace 31 included in the display panel 100 can also be distributed in different metal layers, and the second trace 32 included in the display panel 100 can also be distributed in different metal layers. That is, the film layers corresponding to various traces in the display panel 100 can be adjusted by the user according to the actual product, and this application does not make specific limitations in this regard.

[0141] Figure 12 The diagram shown is another schematic diagram of the display panel provided in an embodiment of this application. Please refer to... Figure 12 Optionally, it includes multiple scan lines 50 arranged along a first direction and extending along a second direction. Each scan line 50 includes a first scan line 51. Each first scan line 51 includes a first sub-first scan line 511 and a second sub-first scan line 512. The first sub-first scan line 511 and the second sub-first scan line 512 are respectively disposed on both sides of the functional device setting area 10.

[0142] The first sub-first scan line 511 and the second sub-first scan line 512 can be electrically connected via the third connecting line 53 and the fourth connecting line 54;

[0143] The third connecting line 53 extends along the first direction, and the fourth connecting line 54 extends along the second direction.

[0144] Specifically, the display panel 100 also includes scan lines 50, the extension direction of which intersects the extension direction of the data lines 20. In one optional embodiment, the scan lines 50 in the display panel 100 include a first scan line 51 that passes through the functional device setting area 10 and a second scan line 52 that does not pass through the functional device setting area 10. Therefore, the first scan line 51 will have a two-segment structure located in the functional device setting area 10. Specifically, the first scan line 51 includes a first sub-first scan line disposed on both sides of the functional device setting area 10. To ensure that the first scan line 51 can receive the same electrical signal, a set of wiring structures can be added to the line 511 and the second sub-first scan line 512. Specifically, this includes two third connecting lines 53 extending along the first direction and one fourth connecting line 54 extending along the second direction. Specifically, one end of one third connecting line 53 is electrically connected to the first end of the fourth connecting line 54 and the other end is electrically connected to the first sub-first scan line 511. One end of the other third connecting line 53 is electrically connected to the second end of the fourth connecting line 54 and the other end is electrically connected to the second sub-first scan line 512.

[0145] By using the above-mentioned configuration, the first scan line 51 located on both sides of the functional device setting area 10 is connected by the added third connecting line 53 and fourth connecting line 54, which helps to ensure the transmission of electrical signals on the scan line 50 in the display panel 100 and ensures the normal display effect of the display panel 100.

[0146] Please continue to refer to Figure 12 Optionally, the third connecting line 53 is made of the same layer and material as the first wiring 31, and the fourth connecting line 54 is made of the same layer and material as the second wiring 32.

[0147] Specifically, this application provides an alternative embodiment. Since both the first trace 31 and the third connecting line 53 extend along the first direction, they can be optionally manufactured on the same layer and using the same process. This avoids the need to add a third connecting line 53 on top of the first trace 31, thus reducing the manufacturing process of the display panel 100 and increasing its manufacturing cost. Furthermore, since both the second trace 32 and the fourth connecting line 54 extend along the second direction, they can also be optionally manufactured on the same layer and using the same process. This avoids the need to add a fourth connecting line 54 on top of the second trace 32, thus reducing the manufacturing process of the display panel 100 and increasing its manufacturing cost. It should be added that the routing method described above also ensures the stability of the electrical signals received by each signal in the display panel 100, improving the display effect of the display panel 100.

[0148] It should also be noted that this application does not limit the first trace 31 to be fabricated in the same layer as the third connecting line 53, nor does it limit the fourth connecting line 54 to be fabricated in the same layer as the second trace 32. Where the number of film layers and space allow, the first trace 31, second trace 32, third connecting line 53, and fourth connecting line 54 can also be fabricated in different layers. Furthermore, this application does not limit all first traces 31, second traces 32, third connecting lines 53, and fourth connecting lines 54 to be located in the same metal layer. That is, the various types of traces included in the display panel 100 can also be distributed in different metal layers. In other words, the user can adjust the film layers corresponding to the various types of traces in the display panel 100 according to the actual product, and this application does not impose specific limitations on this.

[0149] Figure 13 The diagram shown is another schematic diagram of the display panel provided in an embodiment of this application. Please refer to... Figure 12 and Figure 13 Optionally, the display panel 100 includes a non-display area 01, which at least partially surrounds the display area 02;

[0150] At least one fourth connection line 54 is located in the non-display area 01.

[0151] Specifically, when the first scan line 51, separated by the functional device setting area 10, needs to be electrically connected through the third connecting line 53 and the fourth connecting line 54, such as Figure 13 As shown, at least one of the fourth connecting lines 54 provided in the display panel 100 can be placed in the non-display area 01 surrounding the display area 02. Alternatively, if there is enough space in the non-display area 01, all the fourth connecting lines 54 can be placed in the non-display area 01. This arrangement reduces the area occupied by the added fourth connecting lines 54 in the display area 02, avoids interference from the added wiring to other wiring in the display panel 100, and helps to ensure the stability and quality of the display of the screen on the display panel 100.

[0152] Figure 14 The diagram shown is another schematic diagram of the display panel provided in an embodiment of this application. Please refer to... Figure 14 Optionally, the functional device setting area 10 includes a first element setting area 13, a second element setting area 14, and a first non-display area 12. The first non-display area 12 surrounds the first element setting area 13 and the first non-display area 12 surrounds the second element setting area 14. The orthographic projection of the first element setting area 13 onto the plane of the display panel 100 does not overlap with the orthographic projection of the second element setting area 14 onto the plane of the display panel 100.

[0153] At least one first trace 31 is located between the first component setting area 13 and the second component setting area 14.

[0154] Specifically, this application also provides a functional device setting area 10 in the shape of a racetrack, specifically including a first component setting area 13, a second component setting area 14 and a first non-display area 12. The first non-display area 12 surrounds both the first component setting area 13 and the second component setting area 14. That is, there is no display area 02 between the first component setting area 13 and the second component setting area 14. In this case, at least one first trace 31 can be selected to be set through the first non-display area 12 between the first component setting area 13 and the second component setting area 14.

[0155] This configuration reuses the non-display area 01 of the functional device setting area 10 for the setting of the first trace 31, which can reduce the area occupied by the setting of the first trace 31 in the display area 02 and avoid interference of the first trace 31 to other traces in the display panel 100, thus helping to ensure the stability and quality of the display panel 100's screen display.

[0156] Figure 15 The diagram shown is another schematic diagram of the display panel provided in an embodiment of this application. Please refer to... Figure 15Optionally, the first trace 31 includes a first sub-first trace 311 and a second sub-first trace 312. The first sub-first trace 311 is located on the side of the functional device setting area 10 closer to the second sub-second area A22, and the second sub-first trace 312 is located on the side of the functional device setting area 10 away from the second sub-second area A22.

[0157] The second routing line 32 also includes a third sub-second routing line 323. One end of the first sub-second routing line 321 is electrically connected to the first sub-data line 221 and the other end is electrically connected to the first sub-first routing line 311. One end of the third sub-second routing line 323 is electrically connected to the first sub-first routing line 311 and the other end is electrically connected to the second sub-first routing line 312. One end of the second sub-second routing line 322 is electrically connected to the second sub-data line 222 and the other end is electrically connected to the second sub-first routing line 312.

[0158] Specifically, this application also provides an optional configuration method in which the first trace 31 of the first sub-data line 221 and the second sub-data line 222 in the second data line 22 is presented as a two-segment, specifically including a first sub-first trace 311 and a second sub-first trace 312. In this case, along the second direction, the first sub-first trace 311 and the second sub-first trace 312 can be configured to be located in the regions on both sides of the functional device setting area 10, and the region of the second sub-first trace 312 and the region in the extension direction do not overlap with the region of the first sub-first trace 311 and the region in the extension direction. The second routing line 32 is further configured to include three sub-routes, specifically a first sub-second routing line 321, a second sub-second routing line 322, and a third sub-third routing line. One end of the first sub-second routing line 321 is electrically connected to the first sub-data line 221, and the other end is electrically connected to the first sub-first routing line 311. One end of the third sub-second routing line 323 is electrically connected to the first sub-first routing line 311, and the other end is electrically connected to the second sub-first routing line 312. One end of the second sub-second routing line 322 is electrically connected to the second sub-data line 222, and the other end is electrically connected to the second sub-first routing line 312. Thus, the electrical signal for the second data line 22 is achieved through the first routing line 31 and the second routing line 32. The transmission ensures the normal display effect of the display panel 100. In addition, this setting can also enable all data lines 20 located at the edge of the display area 02 to be electrically connected to the components in the lower bezel through the central area of ​​the display area 02 and with the help of the first trace 31 and the second trace 32. This can reduce the trace space required when the data lines 20 are electrically connected to the components in the lower bezel, specifically the trace space in the R-corner area corresponding to the lower bezel of the display panel 100. This can reduce the trace width required in the non-display area 01 of the lower bezel, thereby reducing the lower bezel of the display panel 100 and increasing the screen ratio of the display panel 100.

[0159] Please continue to refer to Figure 15Optionally, the number of first traces 31 on the side of the functional device setting area 10 away from the second sub-second area A22 is K3, and the number of first traces 31 on the side of the functional device setting area 10 close to the second sub-second area A22 is K4, where K3 < K4.

[0160] Specifically, this application provides an optional configuration in which, along the second direction, the functional device setting area 10 is located on one side of the center of the display panel 100, slightly off the edge of the display area 02, such as... Figure 15 As shown, the function setting area is located in the upper left area of ​​the display panel 100. In order to enable more data lines 20 and first traces 31 to be electrically connected to the components in the lower bezel and in the central area of ​​the display area 02, the number of first traces 31 on the side of the function setting area away from the second sub-second area A22 can be set to be less than the number of first traces 31 on the side of the function setting area 10 close to the second sub-second area A22. This allows more traces to be electrically connected to the components in the lower bezel to converge towards the center of the display area 02, thereby reducing the trace space required when the data lines 20 are electrically connected to the components in the lower bezel. Specifically, this reduces the trace space in the R-corner area corresponding to the lower bezel of the display panel 100, thereby reducing the trace width required in the non-display area 01 of the lower bezel. This achieves the effect of reducing the lower bezel of the display panel 100 and increasing the screen ratio of the display panel 100.

[0161] Figure 16 The diagram shown is a schematic representation of a display device provided in an embodiment of this application. Please refer to the provided text for further details. Figures 1-15 , refer to Figure 16 Based on the same inventive concept, this application also provides a display device 200, which includes a display panel 100, and the display panel 100 is any of the display panels 100 provided in this application.

[0162] It should be noted that the embodiments of the display device 200 provided in this application can refer to the embodiments of the display panel 100 described above, and will not be repeated here. The display device 200 provided in this application can be any product and component with display function, such as a mobile phone, tablet computer, television, monitor, laptop computer, or navigator.

[0163] As can be seen from the above embodiments, the display panel and display device provided by the present invention achieve at least the following beneficial effects:

[0164] This application provides a display panel and display device. By using a first trace and a second trace arranged in the central area of ​​the display area along the direction perpendicular to the extension of the data line, electrical signals are transmitted to the data lines corresponding to the functional device setting area and the data lines on the side of the functional device setting area away from the center of the display panel. This avoids the need for the data lines corresponding to the functional device setting area and the data lines on the side of the functional device setting area away from the center of the display panel to be wound in the R-corner area when electrically connected to the flexible circuit board. In other words, this application achieves the purpose of compressing the bottom bezel width and increasing the screen ratio of the display device by eliminating the winding connection of the R-corner data lines.
