Description

Technical Field

[0001] The present invention relates to the field of display technology, and more particularly, to a display panel and a display device. Background Art

[0002] With the diversified design of display panels, a solution has emerged to open a through hole inside the display area of ​​the display panel to set up components such as cameras. Since the through hole opened inside the display area will cut off part of the signal line, when the through hole opened in the display area is wide, the winding used to connect the cut signal line may occupy more space in the border area of ​​the display panel, which is not conducive to the narrow border design of the display panel. Summary of the invention

[0003] In view of this, the present invention provides a display panel and a display device, aiming to achieve a narrow frame design of the display panel.

[0004] In a first aspect, the present invention provides a display panel, comprising: a display area, a first optical device area, a first non-display area, and a second non-display area, wherein the first non-display area surrounds the first optical device area, the display area surrounds the first non-display area, and the second non-display area surrounds the display area;

[0005] The display panel further comprises at least one first signal line and at least one first connection line, wherein the first signal line extends along a first direction in the display area and is terminated at the first optical device area;

[0006] The first connecting line includes an electrically connected first line segment and a second line segment, the first line segment is electrically connected to the first signal line located on a first side of the first optical device area along the first direction, and the second line segment is electrically connected to the first signal line located on a second side of the first optical device area along the first direction; wherein the first line segment is located in the first non-display area, and the second line segment is located in the display area.

[0007] In a second aspect, based on the same inventive concept, the present invention provides a display device, comprising the display panel provided by the first aspect of the present invention.

[0008] Compared with the related art, the display panel and the display device provided by the present invention achieve at least the following beneficial effects:

[0009] In the display panel and the display device provided by the embodiments of the present invention, after the first optical device area is introduced, the first signal line will be divided into two parts by the first optical device area, namely, a first signal line located above the first optical device area along the first direction and a first signal line located below the first optical device area. In order to realize the electrical connection of the first signal lines on the upper and lower sides of the first optical device area, the present invention introduces a first connecting line, and the first connecting line includes an electrically connected first line segment and a second line segment, wherein the first line segment is electrically connected to the first signal line located above the first optical device area, and the second line segment is electrically connected to the first signal line located below the first optical device area. In particular, the first line segment in the first connecting line is located in a first non-display area outside the first optical device area, and the second line segment is located in the display area. Neither the first line segment nor the second line segment will occupy the space of the second non-display area of ​​the display panel, that is, will not occupy the space of the frame area of ​​the display panel, thereby providing a compressed space for the frame of the display panel, which is conducive to realizing a narrow frame design of the product.

[0010] Of course, any product implementing the present invention does not necessarily need to achieve all of the technical effects described above at the same time.

[0029] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention unless otherwise specifically stated.

[0030] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0031] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0032] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0033] It is obvious to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the present invention. Therefore, the present invention is intended to cover modifications and variations of the present invention that fall within the scope of the corresponding claims (technical solutions claimed for protection) and their equivalents. It should be noted that the implementation methods provided in the embodiments of the present invention can be combined with each other without contradiction.

[0034] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0035] Figure 1 The figure shows a wiring diagram near the optical device area NA1 in the display panel provided in the related art. In the related art, when the optical device area NA1 with a larger width is introduced into the display panel, the number of signal lines X cut off by the optical device area NA1 in the display area A0' is relatively large, and connecting lines L are usually introduced to electrically connect the cut off signal lines X. When the optical device area NA1 is close to the border area NA2 of the display panel, there is not enough space in the display area to set the connecting lines, and more connecting lines L will occupy the space of the border area NA2 adjacent to the optical device area NA1, resulting in the enlargement of the border area NA2 of the display panel, which is not conducive to the realization of a narrow border design.

[0036] To this end, the present invention provides a display panel, comprising: a display area, a first optical device area, a first non-display area and a second non-display area, wherein the first non-display area surrounds the first optical device area, the display area surrounds the first non-display area, and the second non-display area surrounds the display area; the display panel also includes at least one first signal line and at least one first connecting line, the first signal line extends along a first direction in the display area and is terminated at the first optical device area; the first connecting line includes an electrically connected first line segment and a second line segment, the first line segment is electrically connected to the first signal line located on a first side of the first optical device area along the first direction, and the second line segment is electrically connected to the first signal line located on a second side of the first optical device area along the first direction; wherein the first line segment is located in the first non-display area, and the second line segment is located in the display area. When the first signal lines on both sides of the optical device area are electrically connected, the present invention utilizes the space of the first non-display area to lay out the first line segment, and utilizes the space of the display area to lay out the second line segment. When this part of the first signal lines is electrically connected, the first connecting lines do not need to occupy the space of the border area of ​​the display panel, which is beneficial to reduce the number of connecting lines laid in the border area of ​​the display area, provides compression space for the border area, and is beneficial to realize the narrow border design of the display panel.

[0037] The above is the core idea of ​​the present invention. The technical scheme in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Based on the embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the embodiment of the present invention.

[0038] Figure 2 FIG. 1 is a schematic plan view of a display panel provided by an embodiment of the present invention. Figure 3 FIG. 1 is a partial schematic diagram of a first optical device area in a display panel provided by an embodiment of the present invention. Please refer to FIG. Figure 2 and Figure 3, an embodiment of the present invention provides a display panel 100, comprising: a display area A0, a first optical device area A01, a first non-display area A11 and a second non-display area A12, wherein the first non-display area A11 surrounds the first optical device area A01, the display area A0 surrounds the first non-display area A11, and the second non-display area A12 surrounds the display area A0; wherein the display area A0 is the area of ​​the display panel where the display area A0 is mainly emitted, and the second non-display area A12 is the area of ​​the display panel where peripheral circuits and packaging are mainly arranged. The location of the first optical device area A01 is mainly used to arrange optical devices, for example, the first optical device area A01 can be arranged with an optical sensor, a camera, a face recognition sensor, a flashlight, etc. In order to enable the optical device arranged in the first optical device area A01 to receive light from the outside or emit light to the outside, and the transmittance of the first optical device area A01 to these lights is greater than the transmittance of the display area A0 to these lights.

[0039] It should be noted that when the optical device in the first optical device zone A01 can emit light to the outside, the optical device in the first optical device zone A01 is different from the sub-pixels in the display area A0, wherein the first optical device zone A01 does not include sub-pixels or includes sub-pixels but the first optical device zone A01 is in a high light transmittance state.

[0040] In addition, in the embodiment of the present application, the first optical device area A01 can be arranged in various forms, for example, the first optical device area A01 includes a through hole or a blind hole. The through hole penetrates the display panel in the thickness direction of the display panel, and can be obtained by cutting the display panel. The blind hole does not penetrate the display panel in the thickness direction of the display panel, and can be obtained by arranging the sub-pixel away from the first optical device area A01.

[0041] Continue to refer Figure 2 and Figure 3 The display panel further includes at least one first signal line X1 and at least one first connection line L1, the first signal line X1 extends along the first direction F1 in the display area A0 and terminates at the first optical device area A01; the first connection line L1 includes an electrically connected first line segment L11 and a second line segment L12, the first line segment L11 is electrically connected to the first signal line X1 located at the first side of the first optical device area A01 along the first direction F1, and the second line segment L12 is electrically connected to the first signal line X1 located at the second side of the first optical device area A01 along the first direction F1; wherein the first line segment L11 is located in the first non-display area A11, and the second line segment L12 is located in the display area A0. Optionally, the first direction F1 is a row direction, and the second direction F2 is a column direction. The first signal line X1 may be a signal line that provides a signal to a sub-pixel in the display panel, for example, the first signal line X1 may provide a data voltage signal to the sub-pixel.

[0042] The first signal line X1 extends along the first direction F1 in the display area A0 and terminates at the first optical device area A01. It can be understood that if the first optical device area A01 is not set, the first signal line X1 will extend along the first direction F1 as a whole. When introduced into the first optical device area A01, the first signal line X1 will be divided into two parts by the first optical device area A01, namely the first signal line X1 located on the first side of the first optical device area A01 (which can be regarded as the upper part) along the first direction F1 and the first signal line X1 located on the second side of the first optical device area A01 (which can be regarded as the lower part). In order to realize the electrical connection of the first signal line X1 on the upper and lower sides of the first optical device area A01, the first connecting line L1 is introduced in the embodiment of the present invention. The first connecting line L1 includes an electrically connected first line segment L11 and a second line segment L12, wherein the first line segment L11 is electrically connected to the first signal line X1 located above the first optical device area A01, and the second line segment L12 is electrically connected to the first signal line X1 located below the first optical device area A01. In particular, the first line segment L11 in the first connecting line L1 is located in the first non-display area A11 outside the first optical device area A01, and the second line segment L12 is located in the display area A0. The first line segment L11 and the second line segment L12 will not occupy the space of the second non-display area A12 of the display panel, that is, they will not occupy the space of the border area of ​​the display panel, thereby providing a compressed space for the border of the display panel, which is conducive to realizing the narrow border design of the display panel.

[0043] Figure 4 Shown Figure 3 A cross-sectional schematic diagram along the AA direction in FIG. 1 shows an optional embodiment of the present invention, in which the second line segment L12 and the first signal line X1 are arranged in different layers.

[0044] When the second line segment L12 located in the display area A0 is arranged in a different layer from the first signal line X1, the layout of the second line segment L12 will not be affected by other signal lines in the film layer where the first signal line X1 is located, that is, there is no need to avoid the signal lines in the film layer where the first signal line X1 is located, which is conducive to simplifying the wiring complexity of the display panel. When the second line segment L12 and the first signal line X1 are arranged in different layers, the two can be electrically connected through the connection hole.

[0045] Optionally, when the second line segment L12 includes line segments extending in the same direction as the first signal line X1 , this part of the line segments in the second line segment L12 may also be disposed in the same layer as the first signal line X1 .

[0046] Optionally, the first line segment L11 in the first connecting line L1 can be set in the same layer as the first signal line X1. In the process of manufacturing the first signal line X1, the first connecting line L1 can be formed in the first non-display area A11. At this time, the end of the first line segment L11 connected to the second line segment L12 can be electrically connected through the connecting hole.

[0047] In some other embodiments of the present invention, the first line segment L11 in the first connecting line L1 can also be set in the same layer as at least part of the line segment in the second line segment L12. In this way, the first line segment L11 can be formed at the same time as this part of the line segment in the second line segment L12 is manufactured. At this time, the end of the first line segment L11 connected to the first signal line X1 can be electrically connected through a connecting hole.

[0048] Continue to refer Figure 3 In an optional embodiment of the present invention, the second line segment L12 includes an electrically connected first sub-segment L121, a second sub-segment L122 and a third sub-segment L123, wherein the first sub-segment L121 and the third sub-segment L123 extend along the second direction F2, the second sub-segment L122 extends along the first direction F1, and the first direction F1 and the second direction F2 intersect; the first sub-segment L121 and the third sub-segment L123 are respectively connected to the two ends of the second sub-segment L122, the first sub-segment L121 is electrically connected to the first line segment L11, and the third sub-segment L123 is electrically connected to the first signal line X1 located on the second side of the first optical device area A01 along the first direction F1.

[0049] This embodiment describes the detailed structure of the second line segment L12. Specifically, the second line segment L12 includes three sub-segments, namely, a first sub-segment L121 and a third sub-segment L123 which are parallel to each other and extend along the second direction F2, and a second sub-segment L122 which extends along the first direction F1. The two ends of the second sub-segment L122 are respectively connected to the first sub-segment L121 and the third sub-segment L123, the first sub-segment L121 is connected to the first line segment L11, and the third sub-segment L123 is connected to the first signal line X1. Considering that the signal lines in the display area A0, such as data lines and gate lines, usually extend in the first direction F1 or the second direction F2, when the second line segment L12 is introduced into the display area A0, the embodiment of the present invention sets the second sub-segment L122 in the second line segment L12 to extend along the first direction F1, and sets the first sub-segment L121 and the third sub-segment L123 to extend along the second direction F2, which is conducive to simplifying the wiring difficulty of the second line segment L12.

[0050] It should be noted that Figure 3 The first signal lines X1 shown in the embodiment are for illustration only and do not represent the number of first signal lines X1 actually included in the display panel. Figure 2 The illustrated embodiment also only illustrates the first signal line X1 that is terminated in the first optical device area A01 , and does not illustrate other signal lines that are terminated in the first optical device area A01 .

[0051] Figure 5 FIG. 1 is another partial schematic diagram of the vicinity of the first optical device area A01 in the display panel provided by an embodiment of the present invention.

[0052] Please refer to Figure 5 In an optional embodiment of the present invention, the display panel further includes at least one second signal line X2 and at least one second connection line L2, the second signal line X2 extends along the first direction F1 in the display area A0 and terminates at the first optical device area A01; the second connection line L2 is located in the first non-display area A11, one end of the second connection line L2 is electrically connected to the second signal line X2 located on the first side of the first optical device area A01 along the first direction F1, and the other end of the second connection line L2 is electrically connected to the second signal line X2 located on the second side of the first optical device area A01 along the first direction F1.

[0053] The second signal line X2 may be a signal line for providing a signal to a sub-pixel in the display panel. For example, the second signal line X2 may provide a data voltage signal to the sub-pixel. Of course, in some other embodiments of the present invention, the second signal line X2 may also be a signal line for providing a bias voltage to a sub-pixel in the display panel, and the present invention does not specifically limit this.

[0054] This embodiment shows a situation where the signal lines terminated in the first optical device area A01 include the first signal line X1 and the second signal line X2, wherein the wiring method of the second connection line L2 connected to the second signal line X2 is different from the wiring method of the first connection line L1 connected to the first signal line X1. Specifically, the second connection line L2 is all located in the first non-display area A11 around the first optical device area A01, one end of which is electrically connected to the second signal line X2 located above the first optical device area A01, and the other end is electrically connected to the second signal line X2 located below the first optical device area A01. With such a configuration, while the second connection line L2 is introduced to realize the electrical connection of the second signal line X2, the second connection line L2 does not need to occupy the space of the second non-display area A12, that is, it does not need to occupy the space of the frame area, thereby further providing a compression space for the frame area of ​​the display panel. When the first connecting line L1 is introduced into the display panel to connect the first signal line X1, and the second connecting line L2 is introduced to connect the second signal line X2, the first signal line X1 and the second signal line X2 will not occupy the frame area of ​​the display panel, which is more conducive to realizing the narrow frame design of the display panel.

[0055] In addition, since the second connection line L2 is only wired in the first non-display area A11, the length of the second connection line L2 is shorter. After the second signal line X2 is connected by the second connection line L2, it is beneficial to reduce the length difference of the second signal line X2 connected by the second connection line L2, so it is also beneficial to reduce the load difference between different second signal lines X2.

[0056] Figure 6 Shown Figure 5A BB cross-sectional view of the display panel in the embodiment shows a film layer schematic diagram of the second connecting line L2 and the second signal line X2 in the display panel. In an optional embodiment of the present invention, the second connecting line L2 and the second signal line X2 are arranged in the same layer.

[0057] Specifically, when the second connection lines L2 connecting the second signal lines X2 are all arranged in the first non-display area A11, the embodiment of the present invention can arrange the second connection lines L2 and the second signal lines X2 in the same layer. In this way, the production of the second connection lines L2 can be completed while the second signal lines X2 are being produced, that is, the second signal lines X2 and the second connection lines L2 can be formed in the same production process, which is beneficial to simplify the wiring process of the second signal lines X2 and the second connection lines L2 and improve the production efficiency of the display panel.

[0058] Of course, in some other embodiments of the present invention, the second connection line L2 and the second signal line X2 may be arranged in different film layers, and the two may be electrically connected via a connection hole, which is not specifically limited in the present invention.

[0059] Optionally, the first signal line X1 and the second signal line X2 in the embodiment of the present invention may be located in the same layer and manufactured by the same process.

[0060] Continue to refer Figure 5 In an optional embodiment of the present invention, the first signal line X1 is located on both sides of the second signal line X2 along the second direction F2, and the second direction F2 intersects with the first direction F1.

[0061] Specifically, when the signal lines that are cut off in the first optical device area A01 include both the first signal line X1 and the second signal line X2, a feasible setting method is to set the first signal line X1 on the opposite sides of the second signal line X2 along the second direction F2, and when the second signal lines X2 on the upper and lower sides of the first optical device area A01 along the first direction F1 are connected by the second connecting line L2, since the second connecting line L2 is completely distributed in the first non-display area A11, the second connecting line L2 can be wired along the area adjacent to the first optical device area A01 in the first non-display area A11, and wiring space is vacated in the first non-display area A11 for the first line segment L11 in the first connecting line L1, and the wiring space is located in the area adjacent to the display area A0 in the first non-display area A11. Since the first line segment L11 in the first connecting line L1 is electrically connected to the second line segment L12 in the display area A0, when the first line segment L11 is disposed in the first non-display area A11 adjacent to the display area A0, it is helpful to simplify the connection difficulty between the first line segment L11 and the second line segment L12.

[0062] Continue to refer Figure 5Optionally, part of the second connection line L2 connected to the second signal line X2 is located on one side of the first optical device area A01 along the first direction F1, and the other part is located on the other side of the first optical device area A01 along the first direction F1. In this way, when the second connection line L2 is arranged in the first non-display area A11, it is beneficial to reasonably utilize the space of the first non-display area A11.

[0063] Continue to refer Figure 5 In an optional embodiment of the present invention, the first signal line X1 includes a first-side first signal line X11 and a second-side first signal line X12, the first-side first signal line X11 is located on a first side of the second signal line X2 along the second direction F2, and the second-side first signal line X12 is located on a second side of the second signal line X2 along the second direction F2; the number of the first-side first signal lines X11 and the second-side first signal lines X12 is the same.

[0064] Specifically, when the first signal line X1 is disposed on two opposite sides of the second signal line X2 along the second direction F2, the first signal line X11 on the first side can be regarded as the first signal line X1 located on the left side of the second signal line X2, and the first signal line X12 on the second side can be regarded as the first signal line X1 located on the right side of the second signal line X2, or the first signal line X11 on the first side can be regarded as the first signal line X1 located on the right side of the second signal line X2, and the second signal line X12 on the second side can be regarded as the first signal line X1 located on the left side of the second signal line X2. In the embodiment of the present invention, when the number of the first signal lines X11 on the first side and the number of the first signal lines X12 on the second side are set to be the same, the first signal lines X11 on the first side and the second signal lines X12 on the second side can be designed in a symmetrical wiring manner on both sides of the second signal line X2, which is conducive to simplifying the wiring difficulty of the first signal line X1 and the second signal line X2.

[0065] Figure 5 The embodiment is described by taking the example that the number of the first signal lines X11 on the first side and the number of the first signal lines X12 on the second side are the same, but in some other embodiments of the present invention, the number of the first signal lines X11 on the first side and the second signal lines X12 on the second side can also be set to be different according to needs, and the present invention does not specifically limit this.

[0066] Continue to refer Figure 5In an optional embodiment of the present invention, the first connection line L1 connected to the first signal line X11 on the first side is wired on the first side of the second signal line X2 along the second direction F2. In this way, there is no need to wind this part of the first connection line L1 to the second side of the second signal line X2 along the second direction F2, which is beneficial to reducing the length of the first connection line L1 connected to the first signal line X11 on the first side, and is beneficial to simplifying the wiring difficulty of the first signal line X11 on the first side and the first connection line L1, and is also beneficial to reducing the overall load of the first signal line X11 on the first side.

[0067] Similarly, the first connection line L1 connected to the first signal line X12 on the second side is wired on the second side of the second signal line X2 along the second direction F2. In this way, there is no need to wind this part of the first connection line L1 to the first side of the second signal line X2 along the second direction F2. This is beneficial to reducing the length of the first connection line L1 connected to the first signal line X12 on the second side, and is beneficial to simplifying the wiring difficulty of the first signal line X12 on the second side and the first connection line L1, and is also beneficial to reducing the overall load of the first signal line X12 on the second side.

[0068] When the number of first signal lines X11 on the first side is the same as the number of first signal lines X12 on the second side, the number of first connection lines L1 respectively connected to these two parts of the first signal lines X1 is also the same. Optionally, the first connection lines L1 respectively connected to these two parts of the first signal lines X1 can be wired in a symmetrical manner to further simplify the wiring difficulty of the first connection lines L1.

[0069] Continue to refer Figure 5 In an optional embodiment of the present invention, in the first non-display area A11, the first line segment L11 is located on the side of the second connection line L2 away from the first optical device area A01. In the first connection line L1 for connecting the first signal line X1, since the first line segment L11 needs to be connected to the second line segment L12 located in the display area A0, when the first line segment L11 is arranged on the side of the second connection line L2 away from the first optical device area A01, the first line segment L11 is closer to the display area A0 than the second connection line L2, so that it is more convenient to connect the first line segment L11 with the second line segment L12 located in the display area A0, which is conducive to simplifying the wiring difficulty of the display panel.

[0070] Figure 7 FIG. 1 is another partial schematic diagram of the vicinity of the first optical device area A01 in the display panel provided by an embodiment of the present invention.

[0071] Please refer to Figure 7In an optional embodiment of the present invention, the display panel further includes at least one third signal line X3 and at least one third connection line L3, the third signal line X3 extends along the first direction F1 in the display area A0 and terminates at the first optical device area A01; the third connection line L3 is located in the display area A0, one end of the third connection line L3 is electrically connected to the third signal line X3 located on the first side of the first optical device area A01 along the first direction F1, and the other end of the third connection line L3 is electrically connected to the third signal line X3 located on the second side of the first optical device area A01 along the first direction F1.

[0072] The third signal line X3 may be a signal line for providing a signal to a sub-pixel in the display panel. For example, the third signal line X3 may provide a data voltage signal to the sub-pixel. Of course, in some other embodiments of the present invention, the third signal line X3 may also be a signal line for providing a bias voltage to a sub-pixel in the display panel, and the present invention does not specifically limit this.

[0073] When the width of the first optical device area A01 along the first direction F1 is large, the number of signal lines in the display area A0 that are cut off at the location of the first optical device area A01 will be large. For example, please refer to Figure 8 In addition to the first signal line X1 and the second signal line X2, the signal line terminated at the location of the first optical device area A01 also includes a third signal line X3. The third signal line X3 terminated at the first optical device area A01 is electrically connected through the third connection line L3, wherein the third connection line L3 is located in the display area A0. Since, in the first connection line L1 connecting the first signal line X1, the first line segment L11 is located in the first non-display area A11, the second line segment L12 is located in the display area A0, the second connection line L2 connecting the second signal line X2 is located in the first non-display area A11, and the third connection line L3 connecting the third signal line X3 is located in the display area A0, the first connection line L1, the second connection line L2 and the third connection line L3 will not occupy the space of the frame of the display panel, which is conducive to realizing the narrow frame design of the display panel.

[0074] Continue to refer Figure 7 In an optional embodiment of the present invention, along the second direction F2, the third signal line X3 is located on a side of the first signal line X1 away from the second signal line X2.

[0075] Specifically, considering that the segment of the third connection line L3 connecting the third signal line X3 is located in the display area A0, there is no need to wire it in the first non-display area A11 outside the first optical device area A01. Therefore, compared with the first signal line X1, the third signal line X3 can be set at a position farther away from the first non-display area A11, for example, on the side of the first signal line X1 away from the second signal line X2 along the second direction F2. In this way, when the third signal line L3 is used to connect the third signal line X3, the wiring of the first connection line L1 and the second connection line L2 will not be affected, which facilitates the wiring of the third connection line L3 and helps to simplify the wiring difficulty of the display panel.

[0076] Continue to refer Figure 7 In an optional embodiment of the present invention, along the second direction F2, the third connection line L3 is located on the side of the first connection line L1 away from the first optical device area A01. In other words, the third connection line L3 is wired outside the first connection line L1, does not occupy the space of the area where the first connection line L1 is located, and the wiring of the third connection line L3 and the wiring of the first connection line L1 do not affect each other, so it is also helpful to simplify the wiring difficulty of the display panel.

[0077] In an optional embodiment of the present invention, continue to refer to Figure 7 The third signal line X3 includes a first-side third signal line X31 and a second-side third signal line X32, the first-side third signal line X31 is located on the first side of the second signal line X2 along the second direction F2, and the second-side third signal line X32 is located on the second side of the second signal line X2 along the second direction F2; the number of the first-side third signal lines X31 and the second-side third signal lines X32 is the same.

[0078] Specifically, when there are many signal lines in the display panel that are terminated at the location of the first optical device area A01, for example, when this part of the signal lines includes the third signal line X3 in addition to the first signal line X1 and the second signal line X2, the third signal line X3 can be evenly distributed on both sides of the second signal line X2 along the second direction F2, for example, the third signal line X31 on the first side is arranged on the side of the first signal line X11 on the first side away from the second signal line X2, and the third signal line X32 on the second side is arranged on the side of the first signal line X12 on the second side away from the second signal line X2. In the embodiment of the present invention, when the number of the third signal lines X31 on the first side and the third signal lines X32 on the second side is set to be the same, the third signal lines X31 on the first side and the third signal lines X32 on the second side can be designed in a symmetrical wiring manner on both sides of the second signal line X2, which is conducive to simplifying the overall wiring difficulty of the first signal line X1, the second signal line X2 and the third signal line X3.

[0079] Figure 7The embodiment is described by taking the example that the number of the third signal lines X31 on the first side and the number of the third signal lines X32 on the second side are the same, but in some other embodiments of the present invention, the number of the third signal lines X31 on the first side and the third signal lines X32 on the second side can also be set to be different according to needs, and the present invention does not specifically limit this.

[0080] Continue to refer Figure 7 In an optional embodiment of the present invention, the third connection line L3 connected to the first-side third signal line X31 is wired on the first side of the second signal line X2 along the second direction F2. In this way, there is no need to wind this part of the third connection line L3 to the second side of the second signal line X2 along the second direction F2, which is beneficial to reducing the length of the third connection line L3 connected to the first-side third signal line X31, and is beneficial to simplifying the wiring difficulty of the first-side third signal line X31 and the third connection line L3, and is also beneficial to reducing the overall load of the first-side third signal line X31, and is also beneficial to balancing the load differences between different first-side third signal lines X31.

[0081] Similarly, the third connection line L3 connected to the third signal line X32 on the second side is wired on the second side of the second signal line X2 along the second direction F2. In this way, there is no need to wind this part of the third connection line L3 to the first side of the second signal line X2 along the second direction F2. This is beneficial to reducing the length of the third connection line L3 connected to the third signal line X32 on the second side, and is beneficial to simplifying the wiring difficulty of the third signal line X32 and the third connection line L3 on the second side. It is also beneficial to reduce the overall load of the third signal line X32 on the second side, and is beneficial to balancing the load differences between different second-side third signal lines X32.

[0082] Figure 8 Shown Figure 7 A CC cross-sectional view of the display panel, please refer to Figure 2 , Figure 7 and Figure 8 In an optional embodiment of the present invention, the third connection line L3 and the second line segment L12 are arranged in the same layer. Since the third connection line L3 and the second line segment L12 in the first connection line L1 are both located in the display area A0, when the third connection line L3 and the second line segment L12 in the first connection line L1 are arranged in the same layer, it is not necessary to arrange the third connection line L3 and the second line segment L12 in different film layers respectively, and the two can share the same film layer, which is conducive to simplifying the film layer structure of the display panel. In addition, when the third connection line L3 and the second line segment L12 are arranged in the same layer, the third connection line L3 and the second line segment L12 can be manufactured and formed in the same process, which is also conducive to simplifying the manufacturing process of the display panel.

[0083] Fig. 9FIG. 1 is another partial schematic diagram of the vicinity of the first optical device area A01 in the display panel provided by an embodiment of the present invention.

[0084] Please refer to Fig. 9 In an optional embodiment of the present invention, two third signal lines X3 connected to each other are electrically connected through at least two third connection lines L3 connected in parallel. It should be noted that this embodiment only shows the manner in which the third signal lines X3 located at the outermost periphery are connected through two third connection lines L3 connected in parallel, and other third signal lines X3 may also be connected using third connection lines L3 connected in parallel.

[0085] Specifically, when the third connection line L3 is wired outside the first connection line L1, the length of the third connection line L3 will be relatively large. After the third signal line X3 is connected through the third connection line L3 with a relatively large length, the load will become larger, and the voltage drop of the signal transmitted on the third signal line X3 will be relatively large. In this embodiment, when two third signal lines X3 are electrically connected through at least two third connection lines L3 connected in parallel, the impedance of the third connection line L3 is reduced by connecting in parallel, thereby reducing the overall load on the third signal line X3, which is conducive to reducing the voltage drop of the signal transmitted on the third signal line X3, so as to balance the voltage drop difference between the third signal line X3 and the first signal line X1 and the second signal line X2.

[0086] Continue to refer Figure 7 In an optional embodiment of the present invention, the third connecting line L3 includes two first sub-lines L31 and a second sub-line L32 respectively connected to the two first sub-lines L31, one of the two first sub-lines L31 is electrically connected to the third signal line X3 located on the first side of the first optical device area A01 along the first direction F1, and the other is electrically connected to the third signal line X3 located on the second side of the first optical device area A01 along the second direction F2, the first sub-line L31 extends along the second direction F2, and the second sub-line L32 extends along the first direction F1.

[0087] This embodiment describes the detailed structure of the third signal line X3. Specifically, the third signal line X3 includes three sub-lines, namely, two first sub-lines L31 that are parallel to each other and extend along the second direction F2, and a second sub-line L32 that extends along the first direction F1, wherein two ends of the second sub-line L32 are respectively connected to different first sub-lines L31, one first sub-line L31 is electrically connected to the third signal line X3 located above the first optical device area A01, and the other first sub-line L31 is connected to the third signal line X3 located below the first optical device area A01. Considering that the signal lines in the display area A0, such as data lines and gate lines, usually extend in the first direction F1 or the second direction F2, when the third signal line X3 is introduced into the display area A0, the embodiment of the present invention sets the second sub-line L32 in the third signal line X3 to extend along the first direction F1, and sets the first sub-line L31 to extend along the second direction F2, which is conducive to simplifying the wiring difficulty of the third signal line X3.

[0088] It should be noted that if the width of the first optical device area A01 along the first direction F1 is large, the signal lines in the display area A0 include, in addition to the first signal line X1, the second signal line X2 and the third signal line X3, the signal lines that are terminated at the position where the first optical device area A01 is located. Fig.10 The fifth signal line X5 in Fig.10Another local schematic diagram near the first optical device area A01 in the display panel provided by an embodiment of the present invention is shown. At this time, the fifth signal line X5 located on the upper and lower sides of the first optical device area A01 can be connected through the fifth connecting line L5. It is assumed that the fifth connecting line L5 includes an electrically connected first sub-route L51, a second sub-route L52 and a third sub-route L53, the first sub-route L51 and the third sub-route L53 extend along the second direction F2, and the second sub-route extends along the first direction F1, wherein the first sub-route L51 is electrically connected to the fifth signal line X5 above the first optical device area A01, and the third sub-route L53 is electrically connected to the fifth signal line X5 below the first optical device area A01, wherein at least part of the line segments of the third sub-route L53 and the second sub-route L52 are located in the display area, and if the space in the display area is insufficient to set the first sub-route L51, the first sub-route L51 can be set in the first border area A121. Since the first connecting line L1, the second connecting line L2 and the third connecting line L3 corresponding to the first signal line X1, the second signal line X2 and the third signal line X3 do not occupy the space of the first border area A121, that is, among the connecting lines corresponding to the signal lines that terminate at the position of the first optical device area A01, only a small number of the fifth connecting lines L5 corresponding to the fifth signal line X5 may occupy the space of the first border area A121. Compared with the method in the related art that a large number of connecting lines need to occupy the space of the first border area A121, the present application is still conducive to reducing the border width of the first border area A121 and realizing the demand for narrowing the border of the display panel.

[0089] Fig.11 The diagram is a partial enlarged schematic diagram of the first optical device area A01 adjacent to the first frame area A121. Figure 2 , Figure 5 , Figure 7 and Fig.11 In an optional embodiment of the present invention, the second non-display area A12 includes a first frame area A121 and a second frame area A122 arranged on both sides of the display area A0 along the first direction F1, along the first direction F1, the interval between the first optical device area A01 and the first frame area A121 is smaller than the interval between the first optical device area A01 and the second frame area A122, and along the direction F11 from the first frame area A121 to the second frame area A122, the width of the first non-display area A11 gradually decreases, and in the first non-display area A11, the width S1 on the side close to the first frame area A121 is greater than the width S2 on the side close to the second frame area A122.

[0090] For more information, see Figure 2In the embodiment of the present invention, the first border area A121 can be regarded as the upper border area of ​​the display panel, and the second border area A122 can be regarded as the lower border area of ​​the display panel. The embodiment of the present invention sets the first light-emitting device area at a position close to the upper border area, which better meets the user's usage requirements.

[0091] Continue to combine Figure 2 , Figure 5 , Figure 7 and Fig.11 In an optional embodiment of the present invention, the first line segment L11 is located in the first non-display area A11 having a larger width. Since the first line segment L11 of the first connecting line L1 and the second connecting line L2 are both located in the first non-display area A11, and the first connecting line L1 is connected to the first signal line X1 located above the first optical device area A01, in the first display area A0, the area where the first line segment L11 and the second connecting line L2 are arranged at the same time is on the side of the first non-display area A11 relatively close to the first border area A121, and the first line segment L11 does not extend to the side of the first non-display area A11 away from the first border area A121. Therefore, the width of the first non-display area A11 close to the first border area A121 can be set to be larger so that this part of the area has enough space to arrange the first line segment L11 and the second connecting line L2. Since only the second connecting line L2 needs to be arranged in the area of ​​the first non-display area A11 away from the first border area A121, and the first line segment L11 does not need to be arranged, the width of this part of the first non-display area A11 can be set to be smaller to reasonably utilize the space of the first non-display area A11.

[0092] Please refer to Figure 2 In an optional embodiment of the present invention, the maximum length of the first optical device area A01 along the first direction F1 is D1, and the maximum length along the second direction F2 is D2, wherein D1>D2, and the second direction F2 intersects the first direction F1. In this way, the first optical component area is in a long strip shape as a whole. Such a design can provide sufficient space for the functional components arranged in the first optical device area A01, improve the user experience, and take into account the screen-to-body ratio of the display panel and the overall appearance of the device.

[0093] Please combine Figure 2 and Fig.11In an optional embodiment of the present invention, along the first direction F1, the geometric center C1 of the first optical device area A01 is located between the geometric center C2 of the first non-display area A11 and the second frame area A122, and the extension direction of the line connecting the geometric center of the first optical device area A01 and the geometric center of the first non-display area A11 is the first direction F1, that is, the geometric center C2 of the first non-display area A11 is set between the first frame area A121 and the geometric center C1 of the first optical device area A01, and the geometric center C2 of the first non-display area A11 is closer to the first frame area A121 than the geometric center C1 of the first optical device area A01.

[0094] In the embodiment of the present application, the outer contour of the first optical device area A01 and the outer contour of the first non-display area A11 are both runway-shaped as an example for explanation. The runway shape is an axisymmetric figure, which can be regarded as a combination of a rectangle and two semicircles, and the two semicircles are located on both sides of the short side of the rectangle. At this time, the geometric center refers to the point where the two diagonals of the rectangle intersect. In this embodiment, compared with the first optical device area A01, when the geometric center of the first non-display area A11 is set to be closer to the first frame area A121, it is equivalent to moving the first non-display area A11 upward relative to the first optical device area A01 as a whole, so that the width of the part of the first non-display area A11 close to the first frame area A121 is greater than the width of the part away from the first frame area A121, so as to use the area with a larger width to set the first line segment L11 and the second connecting line L2, so as to achieve full and reasonable use of the space of the first non-display area A11.

[0095] Fig.12 FIG. 1 is another schematic plan view of a display panel provided by an embodiment of the present invention. Fig.13 The figure shows a partial enlarged schematic diagram of the first optical device area A01 adjacent to the first frame area A121. This embodiment shows a solution of introducing two optical device areas into the display panel.

[0096] Please refer to Fig.12 and Fig.13In an optional embodiment of the present invention, the display panel further includes a second optical device area A02 and a third non-display area A13, the second optical device area A02 and the first optical device area A01 are arranged along the second direction F2, and the second direction F2 intersects with the first direction F1; the third non-display area A13 surrounds the second optical device area A02, and the display area A0 surrounds the third non-display area A13; the maximum length of the first optical device area A01 along the first direction F1 is D1, and the maximum length of the second optical device area A02 along the first direction F1 is D3, and D3<D1. Optionally, in a setting mode, the first optical device area A01 can be used to set a corresponding infrared camera to realize a facial recognition function, and the second optical device area A02 can be used to set a corresponding camera to realize a camera function. The second optical device area A02 and the first optical device area A01 are arranged along the second direction F2, and optionally, the second optical device area A02 and the first optical area A01 can be staggered or non-staggered in the first direction F1.

[0097] The display panel further includes at least one fourth signal line X4 and at least one fourth connection line L4, the fourth signal line X4 extends along the first direction F1 in the display area A0 and terminates at the second optical device area A02; the fourth connection line L4 is located in the third non-display area A13, one end of the fourth connection line L4 is electrically connected to the fourth signal line X4 located at the first side of the second optical device area A02 along the first direction F1, and the other end of the fourth connection line L4 is electrically connected to the fourth signal line X4 located at the second side of the second optical device area A02 along the first direction F1. Optionally, the fourth signal line X4 can be a signal line that provides a data signal for a sub-pixel in the display panel, or a signal line that provides a bias voltage for a sub-pixel in the display panel, etc., and the present invention does not specifically limit this.

[0098] Specifically, when the fourth signal line X4 is terminated at the position of the second optical device area A02, the fourth connecting line L4 can be used to realize the electrical connection of the fourth signal line X4 located above and below the second optical device area A02. In the embodiment of the present invention, the fourth connecting line L4 is arranged in the third non-display area A13 outside the second optical device area A02. At this time, in addition to reasonably utilizing the border of the third non-display area A13, the number of connecting lines of the third non-display area A13 surrounding the outside of the third non-display area A13 can also be reduced, thereby reducing the difference in the extension length of the fourth connecting line L4 corresponding to different fourth signal lines X4, so as to reduce the load difference between different fourth signal lines X4.

[0099] In an optional embodiment of the present invention, the fourth connection line L4 and the fourth signal line X4 are arranged in the same layer. When the fourth connection line L4 and the fourth signal line X4 are arranged in the same film layer, there is no need to increase the number of film layers in the display panel, which is conducive to simplifying the film layer structure of the display panel. In addition, the fourth connection line L4 and the fourth signal line X4 can also be manufactured in the same manufacturing process, which is conducive to simplifying the overall manufacturing process of the display panel.

The display panel also includes a semiconductor layer poly, and the semiconductor layer poly is located on the side of the first metal layer M1 away from the substrate 00, or on the side of the first metal layer M1 toward the substrate 00. Among them, the first metal layer M1 can be, for example, a gate metal layer, and the gate of the transistor in the display panel can be set on the first metal layer M1; the capacitor metal layer MC is used to form a capacitor structure with the first metal layer M1 or the second metal layer M2.

In the embodiment of the present invention, the second line segment L12 in the first connecting line L1, the second connecting line L2 and the third connecting line L3 may be located in the fourth metal layer M4, and the present invention does not specifically limit this.

[0102] Please refer to Fig.13In an optional embodiment of the present invention, the first connecting line L1 includes a first-side first connecting line L01 and a second-side first connecting line L02, the first-side first connecting line L01 is located along the second direction F2 at a first side of the second signal line X2 along the second direction F2, the second-side first connecting line L02 is located along the second direction F2 at a second side of the second signal line X2 along the second direction F2, and the second-side first connecting line L02 is located between the first optical device area A01 and the second optical device area A02.

[0103] In this embodiment, when the second-side first connecting line L02 is arranged between the first optical device area A01 and the second optical device area A02, the second-side first connecting line L02 does not need to be wound on the side of the second optical device area A02 away from the first optical device area A01. While reasonably utilizing the space between the first optical device area A01 and the second optical device area A02, it is also beneficial to reduce the length of the first connecting line L1, and at the same time, it is beneficial to reduce the length difference of the first connecting line L1 corresponding to different second-side first signal lines X12, and further helps to reduce the load difference corresponding to different second-side first signal lines X12.

[0104] In an optional embodiment of the present invention, the number of the first connection lines L01 on the first side and the number of the first connection lines L02 on the second side are the same, which is conducive to simplifying the wiring difficulty of the first connection lines L1. Optionally, the first connection lines L01 on the first side and the first connection lines L02 on the second side can be wired in a symmetrical arrangement, which is conducive to reducing the length difference between the first connection lines L01 on the first side and the first connection lines L02 on the second side, and balancing the load difference corresponding to the first signal line X11 on the first side and the first signal line X12 on the second side. In some other optional embodiments of the present invention, the number of the first connection lines L01 on the first side and the first connection lines L02 on the second side can also be set to be different according to actual needs, and the present invention does not specifically limit this.

[0105] In an optional embodiment of the present invention, the third connection line L3 includes a first-side third connection line L031 and a second-side third connection line L032, the first-side third connection line L031 is located along the second direction F2 at the first side of the second signal line X2 along the second direction F2, and the second-side third connection line L032 is located at the second side of the second signal line X2 along the second direction F2; the third connection line L3 includes a second sub-line L32 extending along the first direction F1, and in at least a portion of the second-side third connection line L032, the second sub-line L32 is located between the first optical device area A01 and the second optical device area A02.

[0106] Specifically, when the signal line terminated in the first optical device area A01 includes the third signal line X3, the third signal lines X3 located at the upper and lower sides of the first optical device area A01 are connected through the third connection line L3 located in the display area A0, the first-side third connection line L031 refers to the third connection line L3 wound from the first side of the first optical device area A01 along the first direction F1, and the second-side third connection line L032 refers to the third connection line L3 wound from the second side of the first optical device area A01 along the first direction F1, wherein at least part of the second-side third connection line L031 is connected to the display area A01 through the third connection line L3 located in the display area A0. The connecting line L032 is wound from the area between the first optical device area A01 and the second optical device area A02, that is, the first sub-line L31 extending along the second direction F2 in at least part of the third connecting line L032 on the second side is located between the first optical device area A01 and the second optical device area A02.

Fig.15 In an optional embodiment of the present invention, in at least a portion of the third connecting lines L032 on the second side, the second sub-lines L32 are located on a side of the second optical device area A02 away from the first optical device area A01.

[0108] Specifically, if the space between the first optical device area A01 and the second optical device area A02 is limited and insufficient to arrange all the second-side third connecting lines L032, part of the third connecting lines L3 can be routed to the side of the second optical device area A02 away from the first optical device area A01, thereby realizing electrical connection of the third signal line X3. Since the length of this part of the third connecting lines L3 is relatively large, in order to reduce the overall impedance of this part of the third signal line X3, the third signal lines X3 located above and below the first optical device area A01 can be connected by at least two parallel third connecting lines L3 to reduce the load difference between this part of the third signal lines X3 and other third signal lines X3.
