Abstract
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] From the CRT (Cathode Ray Tube) era to the LCD (Liquid Crystal Display) era, and now to the OLED (Organic Light-Emitting Diode) and LED display era, the display industry has undergone decades of rapid development. The display industry is now inextricably linked to our lives; from traditional mobile phones, tablets, televisions, and PCs, to today's smart wearable devices, VR, automotive displays, and other electronic devices, all rely heavily on display technology.
[0003] To meet the light-sensing requirements of display products, such as for photography, optical component areas (through-hole, blind-hole, or under-display camera) are typically introduced into the display product to house light-sensing elements such as cameras. However, the introduction of optical component areas interrupts the original wiring in the display product. Current technologies usually reconnect these interrupted wirings by wrapping wires around the optical component area. This method increases the width of the non-display area around the optical component area, making it difficult to achieve a narrow bezel design around the optical component area, thus reducing the screen-to-body ratio of the display product. Summary of the Invention
[0004] In view of this, the present invention provides a display panel and display device, which aims to achieve a narrow bezel design around the optical component area in the product, thereby increasing the screen-to-body ratio of the display product.
[0005] In a first aspect, the present invention provides a display panel including a first display area, a first optical component area, and a second optical component area, wherein the first optical component area and the second optical component area are arranged along a first direction, and the first display area at least partially surrounds the first optical component area and the second optical component area;
[0006] The first display area includes a plurality of first signal lines extending along the first direction. At least a portion of the first signal lines include a first line segment and a second line segment. The first line segment is located between the first optical component area and the second optical component area. The second line segment is located on the side of the first optical component area away from the second optical component area, and / or the second optical component area is located on the side of the second optical component area away from the first optical component area. The first line segment and the second line segment are electrically connected through a first connection trace. At least a portion of the first connection trace is disposed on a different layer from the first line segment and the second line segment.
[0007] Secondly, based on the same inventive concept, the present invention provides a display device including the display panel provided in the first aspect of the present invention.
[0008] Compared with related technologies, the display panel and display device provided by the present invention achieve at least the following beneficial effects:
[0009] The display panel and display device provided in the embodiments of the present invention include a first optical component area and a second optical component area arranged along a first direction. A first display area at least partially surrounds the aforementioned first optical component area and second optical component area. The first display area includes a plurality of first signal lines extending along the first direction. Along the first direction, a portion of the first signal lines overlaps with the first optical component area and the second optical component area. This portion of the first signal lines includes a first line segment and at least one second line segment, wherein the first line segment is located between the first optical component area and the second optical component area, and at least a portion of the second line segment is located on the side of the first optical component area away from the second optical component area, and / or, at least a portion of the second line segment is located on the side of the second optical component area away from the first optical component area. To achieve electrical connection between the first segment and the second segment in the first signal line, this invention introduces a first connection trace in the display panel. At least some segments of the first connection trace are disposed on different layers from the first segment and the second segment in the first signal line. When the first segment and the second segment are connected through the first connection trace, it is not necessary to wrap the trace around the bezel area surrounding the first or second optical component area. This reduces the number of traces corresponding to the bezel area surrounding the first and second optical component areas, providing compression space for the bezels of the first and second optical component areas. Therefore, it is beneficial to achieve a narrow bezel design around the optical component areas corresponding to the first and second optical component areas, which is beneficial to improving the screen ratio of the display panel and the display device.
[0010] Of course, any product implementing this invention does not necessarily need to achieve all of the technical effects described above at the same time.

[0034] 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.
[0035] 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.
[0036] 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.
[0037] 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.
[0038] Various modifications and variations can be made to this invention without departing from its spirit or scope, as will be apparent to those skilled in the art. Therefore, this invention is intended to cover modifications and variations falling within the scope of the corresponding claims (the claimed technical solutions) and their equivalents. It should be noted that the embodiments provided in this invention can be combined with each other without contradiction.
[0039] 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.
[0040] In related technologies, when an optical component area for placing photosensitive elements such as cameras is introduced into a display panel, the signal traces originally located in the optical component area need to be routed around the optical component area. When there are a large number of routed signal traces, the bezel around the optical component area will be wide, which is not conducive to achieving a narrow bezel design around the optical component area, resulting in a reduction in the screen ratio of the display product.
[0041] Therefore, the present invention provides a display panel including a first display area, a first optical component area and a second optical component area, wherein the first optical component area and the second optical component area are arranged along a first direction, and the first display area at least partially surrounds the first optical component area and the second optical component area;
[0042] The first display area includes multiple first signal lines extending along a first direction. At least a portion of the first signal lines includes a first segment and a second segment. The first segment is located between the first optical component area and the second optical component area, and the second segment is located on the side of the first optical component area away from the second optical component area, and / or the second optical component area is located on the side of the second optical component area away from the first optical component area. The first segment and the second segment are electrically connected through a first connecting line. At least a portion of the first connecting line is disposed on a different layer from the first segment and the second segment. By introducing the first connecting line to achieve the electrical connection between the first segment and the second segment of the first signal lines, and because at least a portion of the first connecting line is disposed on a different layer from the first segment and the second segment, it is beneficial to avoid winding around the first optical component area and the second optical component area. This provides space for compressing the bezel areas corresponding to the first optical component area and the second optical component area, which is beneficial to narrowing the bezels corresponding to the first optical component area and the second optical component area, thereby increasing the screen-to-body ratio of the display panel and the display device.
[0043] The above is the core idea of this invention. The technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the embodiments of this invention.
[0044] Figure 1 The diagram shown is a structural schematic of a display panel provided in an embodiment of the present invention. Figure 2 The diagram shown is a schematic representation of another structure of the display panel provided in an embodiment of the present invention. Figure 3The diagram shows a wiring schematic of a first signal line disposed around a first optical component area and a second optical component area, wherein, Figure 1 The diagram illustrates a scheme where the first display area AA completely surrounds the first optical component area A1 and the second optical component area A2. Figure 2 The diagram shows a scheme in which the first display area AA partially surrounds the first optical component area A1 and the second optical component area A2.
[0045] Please refer to Figures 1 to 3 The present invention provides a display panel 100, including a first display area AA, a first optical component area A1 and a second optical component area A2, the first optical component area A1 and the second optical component area A2 are arranged along a first direction D1, and the first display area AA at least partially surrounds the first optical component area A1 and the second optical component area A2.
[0046] The first display area AA includes multiple first signal lines L1 extending along the first direction D1. At least a portion of the first signal lines L1 includes a first line segment L11 and a second line segment L12. The first line segment L11 is located between the first optical component area A1 and the second optical component area A2. The second line segment L12 is located on the side of the first optical component area A1 away from the second optical component area A2, and / or the second optical component area A2 is located on the side of the second optical component area A1 away from the first optical component area A1. The first line segment L11 and the second line segment L12 are electrically connected through a first connecting line. At least a portion of the first connecting line L1 is disposed in a different layer from the first line segment L11 and the second line segment L12.
[0047] Optionally, when the display panel provided in this embodiment of the invention is applied to a display device, the first optical component area A1 and the second optical component area A2 are used to house optical devices such as cameras. During the image capture stage, the optical component areas are used to transmit light. It should be noted that the structure of the first optical component area A1 and the second optical component area A2 in this embodiment of the invention can be one of a non-display through-hole, a non-display blind hole, and a displayable virtual hole (displaying the under-mount camera structure), respectively.
[0048] Specifically, the display panel 100 provided in this embodiment of the invention includes a first optical component area A1 and a second optical component area A2 arranged along a first direction D1. The first display area AA at least partially surrounds the aforementioned first optical component area A1 and second optical component area A2, for example... Figure 1 In the structure shown, the first display area AA completely surrounds the first optical component area A1 and the second optical component area A2, or, for example... Figure 2In the structure shown, the first display area AA partially surrounds the first optical component area A1 and the second optical component area A2. The first display area AA includes multiple first signal lines L1 extending along a first direction D1. Along the first direction D1, a portion of the first signal lines L1 overlaps with the first optical component area A1 and the second optical component area A2. This portion of the first signal lines L1 includes a first line segment L11 and at least one second line segment L12. The first line segment L11 is located between the first optical component area A1 and the second optical component area A2, and at least a portion of the second line segment L12 is located on the side of the first optical component area A1 away from the second optical component area A2, and / or, at least a portion of the second line segment L12 is located on the side of the second optical component area A2 away from the first optical component area A1. This embodiment is illustrated by taking an example where a second line segment L12 is included on each side of the first line segment L11. To achieve electrical connection between the first segment L11 and the second segment L12 in the first signal line L1, the present invention introduces a first connection trace 10 in the display panel. At least some segments of the first connection trace 10 are disposed on different layers from the first segment L11 and the second segment L12 in the first signal line L1. When the first segment L11 and the second segment L12 are connected through the first connection trace 10, it is not necessary to wind around the bezel area outside the first optical component area A1 or the second optical component area A2. This helps to reduce the number of traces corresponding to the bezel area outside the first optical component area A1 and the second optical component area A2, and provides compression space for the bezels of the first optical component area A1 and the second optical component area A2. Therefore, it is beneficial to achieve a narrow bezel design around the optical component areas corresponding to the first optical component area A1 and the second optical component area A2, which helps to improve the screen ratio of the display panel.
[0049] It should be noted that in this embodiment... Figure 1 and Figure 2 This illustration only demonstrates the structure of a display panel. In actual implementations, the structure of the display panel includes, but is not limited to, this. It may also include other structures, such as the film layer structure, pixel circuits, driving circuits, etc. This embodiment will not elaborate on these details; please refer to related art for a better understanding of display panel structures. Figure 1 and Figure 2 This embodiment is illustrated using only a rectangular display panel as an example. In other embodiments of the present invention, the shape of the display panel may also be other, such as a rounded rectangle, a circle, an ellipse, or any other feasible shape. The number of first signal lines L1 overlapping with the first optical component area A1 and the second optical component area A2 along the first direction D1 in this embodiment is also illustrative and does not represent the actual number. Furthermore, Figure 1The illustration is based on the example of a display panel containing two optical component areas. In some other embodiments of the present invention, the display panel may contain three or more optical component areas, and the present invention does not limit this.
[0050] Figure 4 The diagram illustrates a film layer of a display panel according to an embodiment of the present invention. Optionally, the display panel includes a substrate 00, a first metal layer M1, a capacitor metal layer MC, a second metal layer M2, a third metal layer M3, and a fourth metal layer M4 disposed on the substrate 00, with adjacent metal layers isolated by an insulating layer. Optionally, along the thickness direction of the display panel, the capacitor metal layer MC is located between the first metal layer M1 and the second metal layer M2, the third metal layer M3 is located on the side of the second metal layer M2 facing the light-emitting element, and the fourth metal layer M4 is located on the side of the third metal layer M3 facing the light-emitting element. When the display panel includes transistors, optionally, the gate of the transistor is located on the first metal layer M1, and the source and drain are located on the second metal layer M2. At least a portion of the metal on the capacitor metal layer MC is used to overlap with a portion of the metal on the first metal layer M1 or the second metal layer M2 to form a capacitor structure, such as forming a storage capacitor for a pixel circuit on the display panel. Furthermore, the first metal layer M1, the capacitor metal layer MC, the second metal layer M2, the third metal layer M3, and the fourth metal layer M4 can all be used to lay signal lines.
[0051] Optionally, please combine Figures 1 to 4 The first signal line L1 is located in the first metal layer M1 or the capacitor metal layer MC, and at least a portion of the first connection trace 10 is located in the third metal layer M3 or the fourth metal layer M4, etc. However, the actual film structure of the first signal line L1 and the first connection trace 10 is not limited. In the actual film structure, it is only necessary to set the first signal line L1 and at least a portion of the first connection trace 10 in different layers. It should be noted that... Figure 4 This illustration only shows one type of film structure in the display panel and does not represent the actual film layer relationships, number, or size of the display panel.
[0052] Optionally, continue to refer to Figure 4The display panel provided in this embodiment can be a display panel using organic light-emitting diode (OLED) display technology. Optionally, the display panel includes a substrate 00, an array layer 01, a light-emitting layer 02, and an encapsulation layer 03. The basic structure of the light-emitting layer 02 of the OLED display panel typically includes an anode, a light-emitting material layer, and a cathode. When a suitable voltage is supplied, holes in the anode and electrons in the cathode combine in the light-emitting material layer to produce light. Compared to thin-film transistor liquid crystal displays, OLED display devices have high visibility and high brightness, and are more energy-efficient, lightweight, and thinner. Of course, in some other embodiments of the present invention, the display panel can also be a display panel using inorganic light-emitting diode (OLED) display technology, such as a Micro LED display panel, or a Mini LED display panel, etc.
[0053] Continue to refer to Figure 3 In an optional embodiment of the present invention, the first connecting trace 10 includes a first connecting line segment 11 and a second connecting line segment 12. The first connecting line segment 11 extends along a first direction D1, and the second connecting line segment 12 extends along a second direction D2. The first direction D1 and the second direction D2 intersect. The first line segment L11 and the second line segment L12 are electrically connected through the second connecting line segment 12 and the first connecting line segment 11, respectively.
[0054] Specifically, Figure 3 The embodiment shows that the first connection trace 10 is composed of two types of line segments: one is a first connection trace segment 11 extending along the first direction D1, and the other is a second connection trace segment 12 extending along the second direction D2. Optionally, the second direction D2 is perpendicular to the first direction D1. To control the normal display of the display panel, multiple signal lines extending along the first direction D1 and multiple signal lines extending along the second direction D2 are usually provided in the display panel. In this embodiment of the invention, when the first connection trace 10 for connecting the first line segment L11 and the second line segment L12 is introduced, the line segments included in the first connection trace 10 are also set to extend along the first direction D1 or along the second direction D2. This is beneficial for adapting to the extension direction of other traces in the display panel. While realizing the electrical connection of the first line segment L11 and the second line segment L12 to reduce the bezel width corresponding to the optical component area, it also helps to simplify the wiring complexity of the first connection trace 10.
[0055] Continue to refer to Figure 3In an optional embodiment of the present invention, the first connection trace 10 includes a first connection trace segment 11 and at least two second connection trace segments 12 corresponding to the first connection trace segment 11. The first trace segment L11 and the second trace segment L12 are electrically connected to the same first connection trace segment 11 through different second connection trace segments 12.
[0056] Specifically, Figure 3 The illustrated embodiment shows a scheme in which a first segment L11 of a first signal line L1 is connected to two second segments L12 via a first connecting trace 10. The example provided illustrates a scheme where the first connecting trace 10 includes one first connecting trace 11 and three second connecting traces 12 connected to it. In the same first connecting trace 10, one end of each of the three second connecting traces 12 is electrically connected to a second segment L12 located on the side of the first optical component region A1 away from the second optical component region A2, a first segment L11 located between the first optical component region A1 and the second optical component region A2, and a second segment L12 located on the side of the second optical component region A2 away from the first optical component region A1, respectively. The other ends of the three second connecting traces 12 are connected to the same first connecting trace 11. In this way, it is equivalent to connecting the first connecting line segment 11 and the first signal line L1 in parallel through three second connecting lines 12. This not only enables signal transmission between the first line segment L11 and the second line segment L12 connected by the first connecting line 10, but also helps to reduce the overall impedance of the first signal line L1. This avoids the problem of the overall impedance of the first signal line L1 increasing after the introduction of the first connecting line 10. Therefore, while achieving the narrowing design of the bezel area corresponding to the optical component area, it also helps to ensure the reliable transmission of the signal on the first signal line L1.
[0057] Figure 5 The diagram shows another wiring schematic of the first signal line L1 disposed around the first optical component area A1 and the second optical component area A2, and... Figure 3 The difference in the illustrated embodiment is that this embodiment shows a scheme in which the same first line segment L11 is connected to the first connecting line segment 11 through two second connecting line segments 12.
[0058] Please refer to Figure 5 In an optional embodiment of the present invention, the same first line segment L11 is connected to the first connecting line segment 11 through at least two second connecting lines 12.
[0059] Specifically, in this embodiment, the first line segment L11 located between the first optical component area A1 and the second optical component area A2 is connected to different second connection lines 12, and is connected to the same first connection line segment 11 through different second connection lines 12. In this way, the signal on the first connection line segment 11 can be transmitted to the same first line segment L11 through two second connection lines 12, thereby ensuring the accuracy and reliability of the signal received on the first line segment L11 and guaranteeing the normal display function between the first optical component area A1 and the second optical component area A2. Furthermore, the method of connecting the same first line segment L11 to the same first connection line segment 11 through at least two second connection lines 12 also helps to further reduce the overall impedance on the first signal line 10, improving the accuracy and stability of signal transmission between the first line segment L11 and the second line segment L12.
[0060] It should be noted that, although Figure 5 Only the scheme of connecting the same first line segment L11 to the same first line segment L11 through two second connecting lines 12 is shown. However, the number of second connecting lines 12 connected to the same first line segment L11 is not limited. In some other embodiments of the present invention, the same first connecting line segment L11 can also be connected to the same first connecting line segment L11 through three or more second connecting lines 12. The present invention does not specifically limit this.
[0061] Figure 6 The diagram shows another wiring schematic of the first signal line L1 disposed around the first optical component area A1 and the second optical component area A2, and... Figure 3 and Figure 5 Compared to the illustrated embodiment, in this embodiment, the same first connection trace 10 includes two or more first connection trace segments 11.
[0062] Please refer to Figure 6 In an optional embodiment of the present invention, the first connecting trace 10 includes a plurality of (at least two) first connecting trace segments 11 and a plurality of second connecting trace segments 12. The first trace segments L11 are respectively connected to the first ends of different first connecting trace segments 11 through different second connecting trace segments 12, and the second ends of different first connecting trace segments 11 are respectively connected to different second trace segments L12.
[0063] Specifically, this embodiment shows a scheme in which the number of first connection trace segments 11 included in the same first connection trace 10 is the same as the number of optical component areas. That is, when a first optical component area A1 and a second optical component area A2 are provided, the same first connection trace 10 includes two first connection trace segments 11. Optionally, the two first connection trace segments 11 corresponding to the same first connection trace 10 are located on the same side of the first optical component area A1 and the second optical component area A2 along the second direction D2, respectively. In this embodiment, the first line segment L11 is connected to different first connection lines 11 through two different second connection lines 12. For example, the end of the first line segment L11 near the first optical component area A1 is electrically connected to the first connection line 11 located on the upper or lower side of the first optical component area A1. The first connection line 11 is also electrically connected to the second line segment L12 on the left side of the first optical component area A1 through another second connection line 12. The end of the first line segment L11 near the second optical component area A2 is electrically connected to the first connection line 11 located on the upper or lower side of the second optical component area A2. The first connection line 11 is also electrically connected to the second line segment L12 on the right side of the second optical component area A2 through another second connection line 12. Thus, the second line segment L12 on the left side of the first optical component area A1, the first line segment L11 between the first optical component area A1 and the second optical component area A2, and the second line segment L12 on the right side of the second optical component area A2 are connected in series through the first connecting line segment 11 and the second connecting line segment 12 in the first connecting line 10, thereby realizing the signal transmission on the first line segment L11 and the second line segment L12 in the first signal line L1.
[0064] The foregoing embodiment illustrates a scheme in which the first connection trace segment 11 of the first connection trace 10 is located on the same side of the first optical component area A1 and the second optical component area A2 along the second direction D2. In this case, the first connection trace segment 11 corresponding to each first connection trace 10 can be located above the first optical component area A1 and the second optical component area A2, or the first connection trace segment 11 corresponding to each first connection trace 10 can be located below the first optical component area A1 and the second optical component area A2. The present invention does not specifically limit this.
[0065] In some other embodiments of the present invention, the first connection trace segment 11 corresponding to the first connection trace 10 may be respectively disposed above and below the first optical component area A1 and the second optical component area A2, for example, please refer to Figure 5 and Figure 7 , Figure 7 The diagram shows another wiring schematic of the first signal line L1 located around the first optical component area A1 and the second optical component area A2.
[0066] Continue to refer to Figure 5 and Figure 7 In an optional embodiment of the present invention, a portion of the first connecting trace segment 11 is located on the first side of the first optical component area A1 and the second optical component area A2 along the second direction D2, and a portion of the first connecting trace segment 11 is located on the second side of the first optical component area A1 and the second optical component area A2 along the second direction D2, with the first side and the second side opposite to each other.
[0067] Specifically, when a first connection trace 10 is introduced into the display panel to realize the electrical connection between the first segment L11 and the second segment L12 in the first signal line L1, in this embodiment, the first connection trace segment 11 extending along the first direction D1 of the first connection trace 10 is respectively set on both sides of the first optical component area A1 and the second optical component area A2 along the second direction D2, so that the first connection trace 10 is arranged as evenly as possible on the upper and lower sides of the first optical component area A1 and the second optical component area A2. For example, on the same side of the first optical component area A1 or the second optical component area A2, the distance between two adjacent first connection trace segments 11 is equal. In this way, on the one hand, the surrounding space of the first optical component area A1 and the second optical component area A2 can be reasonably utilized, and on the other hand, it is also beneficial to improve the screen-off mura phenomenon that may be caused by the uneven distribution of the first connection trace 10 on the upper and lower sides of the first optical component area A1 and the second optical component area A2.
[0068] Optionally, the number of first connecting traces 11 on both sides of the first optical component area A1 along the second direction D2 is the same or approximately the same, the number of first connecting traces 11 on both sides of the second optical component area A2 along the second direction D2 is the same or approximately the same, and the spacing between two adjacent first connecting traces 11 is the same, so as to further improve the wiring uniformity of the first connecting traces 10.
[0069] It should be noted that when the first signal line L1 overlaps with the first optical component area A1 or the second optical component area A2 along the first direction D1, the length of these first signal lines L1 differs from that of a conventional first signal line L1, resulting in different impedances. In this case, the impedance difference between the different first signal lines can be balanced by adjusting the length of the first connecting trace connecting the first and second segments. Among multiple first signal lines overlapping with the first or second optical component area along the first direction, when the lengths of the first or second optical component area along the first direction differ, the length loss of different first signal lines will vary. In this case, the impedance difference between these first signal lines can also be balanced by differentiating the lengths of the first connecting traces corresponding to the different first signal lines. Among the multiple first signal lines that overlap with the first optical component area or the second optical component area along the first direction, when the length of some first signal lines is the same, since the lengths of the first connection traces corresponding to different first signal lines may be different, in order to balance the impedance difference between the first signal lines, the cross-sectional area of the first connection traces with different lengths can be changed. For example, the cross-sectional area of the longer first connection trace can be set to be smaller than the cross-sectional area of the shorter first connection trace; or, at least some segments of the first connection traces that are closer to the first optical component area and the second optical component area can be set as broken lines or curves, and the segments of the first connection traces that are farther from the first optical component area and the second optical component area can all be set as straight lines, so that the lengths of different first connection traces are close or the same, which is also beneficial to balancing the impedance difference between different first signal lines.
[0070] Please combine Figures 3 to 7 In one optional embodiment of the present invention, the first connection trace segment 11 corresponding to different first signal lines L1 is arranged on the same layer, the second connection trace segment 12 is arranged on the same layer, and the first connection trace segment 11 and the second connection trace segment 12 are arranged on different layers.
[0071] Specifically, in this embodiment, the first connecting line segment 11 extending along the first direction D1 of the first connecting line 10 is placed in the same film layer, while the second connecting line segment 12 extending along the second direction D2 is placed in another film layer. Although the extending directions of the first connecting line segment 11 and the second connecting line segment 12 are different, their arrangement will not interfere with each other. When electrical connection is required, it can be achieved by drilling holes. This design simplifies the wiring of the first connecting line segment 11 and the second connecting line segment 12 in the first connecting line 10, and improves the wiring efficiency of the first connecting line 10.
[0072] Figure 8The diagram illustrates one possible connection between the first signal line L1 and the shift register 90. Optionally, the bezel area B0 of the display panel is provided with multiple shift registers 90 to provide signals to the first signal line L1. When the first line segment L11 located between the first optical component area A1 and the second optical component area A2 is electrically connected to the second line segments L12 on both sides of the two optical component areas, only one of the two second line segments L12 connected to the first line segment L11 needs to be connected to the shift register 90. The signal provided by this shift register 90 can be transmitted to the first line segment L11 and the other second line segment L12 through the directly connected second line segment L12, thereby realizing signal transmission between different segments on the same first signal line L1. This method helps reduce the number of shift registers 90 in the display panel, thus facilitating the narrow bezel design of the display panel.
[0073] Of course, in some other embodiments of the present invention, when the first line segment L11 is connected to the second line segment L12 located on both sides of it through the first connecting line 10, the two second line segments L12 on both sides of the first line segment L11 can also be connected to the shift register, thereby realizing the bilateral driving of the first signal line 10, so as to improve the driving capability of the first signal line 10 to the light-emitting elements in the display panel.
[0074] Figure 9 The diagram shows another wiring schematic of the first signal line L1 disposed around the first optical component area A1 and the second optical component area A2. Figure 10 As shown Figure 9 A schematic diagram of the connection between the first signal line L1 and the shift register 90.
[0075] Please refer to Figure 9 and Figure 10 In an optional embodiment of the present invention, the second line segment L12 includes a second line segment A L121 and a second line segment B L122. The second line segment A L121 is located on the side of the first optical component area A1 away from the second optical component area A2, and the second line segment B L122 is located on the side of the second optical component area A2 away from the first optical component area A1. The first line segment L11 is electrically connected to only one of the second line segment A L121 and the second line segment B L122. The display panel includes a plurality of shift registers 90, and the second line segment A L121 and the second line segment B L122 are respectively connected to different shift registers 90.
[0076] Specifically, Figure 9 and Figure 10The illustrated embodiment shows a scheme in which a first line segment L11 located between a first optical component region A1 and a second optical component region A2 is electrically connected only to a second line segment L12 located on the side of the first optical component region A1 away from the first line segment L11. In some other embodiments of the invention, the first line segment L11 may also be electrically connected only to a second line segment L12 located on the side of the second optical component region A2 away from the first line segment L11. When a second line segment A121 and a second line segment L122 are respectively provided on the side of the first optical component region A1 away from the first line segment L11 and the side of the second optical component region A2 away from the first line segment L11, and the first line segment L11 is electrically connected only to the second line segment A121 or only to the second line segment L122, the second line segment A121 and the second line segment L122 are respectively electrically connected to different shift registers 90. Figure 9 and Figure 10 For example, the signal of shift register 90 connected to the second line segment L121 (A) can be transmitted through the second line segment L121 to the first line segment L11 corresponding to the second line segment L121, so that the area between the first optical component area A1 and the second optical component area A2 can perform normal display function; the signal of shift register 90 connected to the second line segment L122 (B) is provided to the second line segment L122 (B), so that the area of the second light-emitting component area A2 away from the first light-emitting component area A1 can perform normal display function. This arrangement, while ensuring normal display function between the first optical component area A1 and the second optical component area A2, also helps to reduce the number of first connection traces 10 actually introduced around the first optical component area A1 and the second optical component area A2, thereby simplifying the wiring complexity of the first connection traces 10.
[0077] Figure 11 The diagram shown is a schematic representation of another structure of the display panel provided in an embodiment of the present invention. Please refer to it. Figure 11 In an optional embodiment of the present invention, the first display area includes a first side B1 and a second side B2 opposite to each other along a first direction D1. The first side B1 is located on the side of the first optical component area A1 away from the second optical component area A2, and the second side B2 is located on the side of the second optical component area A2 away from the first optical component area A1. The distance between the first side B1 and the edge of the first optical component area A1 near the second optical component area A2 is D11, and the distance between the second side B2 and the edge of the second optical component area A2 near the first optical component area A1 is D12, wherein D11 > D12, and the first line segment L11 is electrically connected only to the second line segment L121.
[0078] Optionally, the width of the first optical component area A1 along the first direction D1 is greater than the width of the second optical component area A2 along the first direction D1. When the distance D11 between the edge of the first optical component area A1 near the second optical component area A2 and the first side B1 is greater than the distance D12 between the edge of the second optical component area A2 near the first optical component area A1 and the second side B2, the first signal line L1 is missing a lot at the corresponding position in the first optical component area A1. At this time, when the first line segment L11 and the second line segment L121 are electrically connected by the first connecting trace 10, it is beneficial to make up for the loading difference between the first line segment L11 and the second line segment L121 and the first signal line L1 in other normal areas, thereby improving the accuracy and stability of signal transmission on the first signal line L1.
[0079] Figure 12 The diagram shows another wiring schematic of the first signal line L1 located around the first optical component area A1 and the second optical component area A2. This embodiment shows a scheme in which the first line segment L11 is connected to the second line segment L122 via the first connecting line 10, and connected to the second line segment L121 via the first winding line L10.
[0080] Please refer to Figure 12 In one optional embodiment of the present invention, the second line segment L12 includes a second line segment A L121 and a second line segment B L122. The second line segment A L121 is located on the side of the first optical component area A1 away from the second optical component area A2, and the second line segment B L122 is located on the side of the second optical component area A2 away from the first optical component area A1.
[0081] The first end of the first line segment L11 is electrically connected to one of the second line segments L121 (A) and L122 (B) via the first connecting line 10. The second end of the first line segment L11 is electrically connected to the other of the second line segments L121 (A) and L122 (B) via the first winding line L10. The first winding line L10 is arranged on the same layer as the first line segment L11, the second line segment L121 (A), and the second line segment L122 (B).
[0082] Optional, with Figure 12Taking the implementation method as an example, when the width of the first optical component area A1 along the second direction D2 is smaller than the width of the second optical component area A2 along the second direction D2, the number of first signal lines L1 overlapping with the first optical component area A1 along the first direction D1 will be less than the number of first signal lines L1 overlapping with the second optical component area A2. In this case, the first end of the first line segment L11 can be electrically connected to the second line segment L121 by a smaller number of first windings L0. When the second end of the first line segment L11 is electrically connected to the second line segment L122 by the first connecting trace 10, it is beneficial to avoid the phenomenon that the bezel width around the second optical component area A2 is too large due to setting too many windings in the second optical component area A2. This arrangement reduces the number of first connecting traces 10 introduced in the display panel, which helps to simplify the wiring difficulty of the first connecting traces 10, and also helps to narrow the bezels around the first optical component area A1 and the second optical component area A2.
[0083] Figure 13 The diagram shows another wiring schematic of the first signal line L1 located around the first optical component area A1 and the second optical component area A2. This embodiment shows a scheme in which the first line segment L11 is connected to the second line segment L122 via the first connecting line 10, and connected to the second line segment L121 via the first winding line L10.
[0084] Please refer to Figure 13 In an optional embodiment of the present invention, along the second direction D2, the width of the first optical component area A1 is greater than the width of the second optical component area A2, and the second direction D2 intersects with the first direction D1; the first line segment L11 is electrically connected to the second line segment L121 via the first connecting line 10, and is electrically connected to the second line segment L122 via the first winding line L10.
[0085] by Figure 13Taking the illustrated embodiment as an example, the width of the second optical component area A2 along the second direction D2 is smaller than the width of the first optical component area A1 along the second direction D2. In this case, the number of first signal lines L1 overlapping with the second optical component area A2 along the first direction D1 will be less than the number of first signal lines L1 overlapping with the first optical component area A1. If the first line segment L11 is connected to the second line segment L121 and the second line segment L122 by winding, the number of windings in the first optical component area A1 will be excessive, leading to an excessively wide border around the first optical component area A1. Therefore, in this embodiment, when the first line segment L11 is connected to the second line segment L121 by the first connecting trace 10, since the first connecting trace 10 is disposed in a different layer from the first line segment L11 and the second line segment L121, the first connecting trace 10 no longer occupies the border space of the first optical component area A1, thus facilitating a narrower border around the first optical component area A1. Because the number of first signal lines L1 overlapping with the second optical component area A2 along the second direction D2 is relatively small, even when the first line segment L11 and the second line segment L122 are electrically connected through the first winding, the number of windings in the bezel area around the second optical component area A2 will be small, thus avoiding the problem of an excessively large bezel around the second optical component area A2. Therefore, the above design is beneficial for achieving an overall narrow bezel design around the first optical component area A1 and the second optical component area A2, thereby increasing the screen-to-body ratio of the display panel.
[0086] Figure 14 The diagram illustrates the relative positional relationship between a portion of a line segment in the first connection trace 10 and the fixed voltage signal line X0 in the display panel. This embodiment only uses the example of the fixed voltage signal line X0 being located in the second metal layer M2 and at least a portion of a line segment in the first connection trace 10 being located in the fourth metal layer M4 for illustration. However, it does not limit the actual film layers of the fixed voltage signal line X0 and the first connection trace 10. In some other embodiments of the present invention, the first connection trace 10 may also be located in other film layers or distributed across at least two different film layers, and the fixed voltage signal line X0 may also be located in other film layers. Furthermore... Figure 14 This illustration only shows a portion of the film layer structure in the display panel and does not represent all the film layer structures actually contained in the display panel. Please refer to [the documentation / reference needed]. Figure 14 In an optional embodiment of the present invention, the display panel includes a fixed voltage signal line X0, and at least a portion of the first connecting trace 10 overlaps with the fixed voltage signal line X0 along the thickness direction of the display panel.
[0087] Optionally, the display panel includes multiple pixel circuits, the structure of which can be found in, for example, by referring to... Figure 15 ,but Figure 15 The pixel circuit shown is for illustrative purposes only and does not limit the actual structure of the pixel circuit contained in the display panel. Figure 15 The diagram shown is a schematic representation of a pixel circuit provided in an embodiment of the present invention. This pixel circuit is used to drive the light-emitting element D in a display panel to emit light. Figure 15 Taking the illustrated embodiment as an example, the pixel driving circuit includes one driving transistor T0 and six switching transistors T1 to T6. Except for the driving transistor T0, the remaining transistors are all switching transistors. The gates of the switching transistors are electrically connected to control lines X. Driving signals are provided to the switching transistors via control lines X to control their on / off states. Optionally, the control lines X connected to the switching transistors are routed on the display panel along a first direction D1. The first signal line L1 mentioned in this embodiment includes the aforementioned control lines X. Optionally, the pixel circuit includes a data writing module 61, a compensation module 62, a first reset module 63, a second reset module 64, and a light emission control module 65. The control line X includes a first control line S1N connected to the control terminals of the first reset module 63 and the second reset module 64, a second control line S2N connected to the control terminal of the compensation module 62, a fourth control line SP connected to the control terminal of the data writing module 61, and a light emission control line EMIT connected to the light emission control module 65. The signal line connected to the data writing module 61 is a data line Vdata, the signal line connected to the first reset module 63 is a first reset signal line VREF1, the signal line connected to the second reset module 64 is a second reset signal line VREF2, the signal line connected to the light emission control module 65 is a first power signal line VDD, and the signal line connected to the light-emitting element D is a second power signal line VEE. The control lines connected to the pixel circuit are used to transmit variable signals, while the first reset signal line VREF1, the second reset signal line VREF2, the first power signal line VDD, and the second power signal line VEE are used to transmit fixed voltage signal lines. Since the signal on the fixed voltage signal line is constant, please refer to... Figure 14 When at least a portion of the first connection trace 10 is overlapped with the fixed voltage signal line X0 along the thickness direction of the display panel, the signal on the fixed voltage signal line X0 has a smaller impact on the signal on the first connection trace 10. Moreover, the way in which at least a portion of the first connection trace 10 introduced into the display panel overlaps with the existing fixed voltage signal line on the display panel also helps to reduce the screen-off mura problem of the display panel.
[0088] Optionally, when the fixed voltage signal line X0 is manifested as a power signal line, such as a first power signal line VDD or a second power signal line VEE, the fixed voltage signal line X0 may include a segment extending along a first direction D1 and a segment extending along a second direction D2. In this case, along the thickness direction of the display panel, the first connection trace segment 11 extending along the first direction D1 in the first connection trace 10 can be configured to overlap with the segment extending along the first direction D1 in the fixed voltage signal line, and the second connection trace segment 12 extending along the second direction D2 in the first connection trace 10 can be configured to overlap with the segment extending along the second direction D2 in the fixed voltage signal line. This helps to further reduce the screen-off mura problem that may occur when the first connection trace 10 is introduced into the display panel. In some optional embodiments of the present invention, along the thickness direction of the display panel, the first connection trace 10 can be disposed within the range defined by the fixed voltage signal line.
[0089] Figure 16 The diagram shows a wiring schematic of a first signal line L1 and a second signal line L2 disposed around a first optical component area A1 and a second optical component area A2. Please refer to the diagram. Figure 16 In an optional embodiment of the present invention, the first display area further includes a second signal line L2 extending along a second direction D2, which intersects with a first direction D1; a portion of the second signal line L2 includes a third segment L23 and a fourth segment L24, the third segment L23 being located on the first side of the first optical component area A1 and the second optical component area A2 along the second direction D2, and the fourth segment L24 being located on the second side of the first optical component area A1 and the second optical component area A2 along the second direction D2, the third segment L23 and the fourth segment L24 being connected by a second connecting trace 20, and at least a portion of the second connecting trace 20 being disposed on a different layer from the third segment L23 and the fourth segment L24.
[0090] Specifically, Figure 16The illustrated embodiment shows a wiring diagram of the second signal line L2 extending along the second direction D2 and overlapping with the first optical component area A1 or the second optical component area A2. The second signal line L2 overlapping with the first optical component area A1 or the second optical component area A2 along the second direction D2 includes a third segment L23 and a fourth segment L24 respectively disposed on the upper and lower sides of the first optical component area A1 or the second optical component area A2. To achieve electrical connection between the third segment L23 and the fourth segment L24, a second connecting trace 20 is introduced in this embodiment to electrically connect the third segment L23 and the fourth segment L24. Since at least some segments of the second connecting trace 20 are set on different layers from the third segment L23 and the fourth segment L24, when the second connecting trace 20 is used to connect the third segment L23 and the fourth segment L24, the second connecting trace 20 does not need to be wound around the first optical component area A1 or the second optical component area A2. Therefore, it is beneficial to reduce the number of windings set in the bezels around the first optical component area A1 and the second optical component area A2, which is beneficial to realize the narrow bezel design around the first optical component area A1 and the second optical component area A2, and to improve the screen ratio of the display panel.
[0091] Continue to refer to Figure 16 In an optional embodiment of the present invention, the second connection trace 20 includes a third connection trace segment 23 and a fourth connection trace segment 24. The third connection trace segment 23 extends along the second direction D2, and the fourth connection trace segment 24 extends along the first direction D1. The third trace segment L23 and the fourth trace segment L24 are electrically connected through different fourth connection trace segments 24 and third connection trace segments 23, respectively.
[0092] When the second signal line L2 overlaps with the first optical component area A1 or the second optical component area A2 along the second direction D2, a second connecting trace 20 is introduced in this embodiment to achieve electrical connection between the third segment L23 and the fourth segment L24 in the second signal line L2. Specifically, the second connecting trace 20 includes a third connecting trace segment 23 extending along the second direction D2 and a fourth connecting trace segment 24 extending along the first direction D1. In actual connection, the third segment L23 and the fourth segment L24 to be connected are respectively connected to different fourth connecting trace segments 24, and then connected to the same third connecting trace segment 23 through the fourth connecting trace segment 24. Setting the segments of the second connecting trace 20 to extend along the first direction D1 or along the second direction D2 is adapted to the extension direction of the existing segments in the first display area of the display panel. While achieving the narrow bezel design of the first optical component area A1 and the second optical component area A2 by introducing the second connecting trace 20, it also helps to simplify the wiring difficulty of the second connecting trace 20.
[0093] Optionally, when the second connection trace 20 is introduced into the first display area, along the thickness direction of the display panel, the second connection trace 20 can be configured to overlap with the fixed voltage signal lines in the display panel. For example, the fourth segment L24 of the second connection trace 20 extending along the first direction D1 overlaps with the segment of the fixed voltage signal line extending along the first direction D1, and the third segment L23 of the second connection trace 20 extending along the second direction D2 overlaps with the segment of the fixed voltage signal line extending along the second direction D2. Since the signal in the fixed voltage signal line is constant, this avoids the influence of the transient signal in other signal lines on the signal transmitted by the second connection trace 20 when the second connection trace 20 overlaps with other signal lines, and also improves the screen-off mura phenomenon when the second connection trace 20 is introduced into the display panel. To further avoid the screen-off mura phenomenon, the second connection trace 20 can also be entirely set within the range defined by the fixed voltage signal lines along the thickness direction of the display panel.
[0094] Continue to refer to Figure 16 In one optional embodiment of the present invention, at least a portion of the second connection traces 20 are located on the side of the first optical component area A1 away from the second optical component area A2, and at least a portion of the second connection traces 20 are located on the side of the second optical component area A2 away from the first optical component area A1.
[0095] When a first optical component area A1 and a second optical component area A2 are introduced into the display panel, the space between the first optical component area A1 and the second optical component area A2 is small and needs to perform display functions. When a second connecting trace 20 is introduced to realize the electrical connection between the third segment L23 and the fourth segment L24 in the second signal line L2, in this embodiment, part of the third connecting trace segment 23 extending along the second direction D2 in the second connecting trace 20 is set on the side of the first optical component area A1 away from the second optical component area A2, and the other part of the third connecting trace segment 23 is set on the side of the second optical component area A2 away from the first optical component area A1. In this way, the second connecting trace 20 does not need to occupy the small space between the first optical component area A1 and the second optical component area A2, which is conducive to realizing reasonable wiring of the second connecting trace L22 in the display panel and reducing the wiring complexity of the second connecting trace 20.
[0096] Figure 17 and Figure 18 The diagrams shown are alternative wiring diagrams of the first signal line L1 and the second signal line L2 disposed around the first optical component area A1 and the second optical component area A2, respectively. Figure 17 and Figure 18 The specific structure of the first optical component region A1 is detailed in the embodiment.
[0097] Optionally, the first optical component area A1 includes two sub-optical component areas, namely, a first sub-optical component area A11 and a second sub-optical component area A12 arranged along the first direction D1. Optionally, the first sub-optical component area A11, the second sub-optical component area A12, and the second optical component area A2 are all circular, but the present invention is not limited thereto. A first interval area is provided between the first sub-optical component area A11 and the second sub-optical component area A12. Figure 17 In the embodiment shown, the second connection trace 20 is not laid out in the first interval area. This arrangement helps to reduce the wiring density in the first interval area.
[0098] Please refer to Figure 18 In an optional embodiment of the present invention, the first optical component area A1 includes a first sub-optical component area A11 and a second sub-optical component area A12, the first sub-optical component area A11 and the second sub-optical component area A12 are arranged along a first direction D1, and a first gap area is provided between the first sub-optical component area A11 and the second sub-optical component area A12; in the thickness direction of the display panel, at least a portion of the second connection trace 20 overlaps with the first gap area.
[0099] Specifically, Figure 18 In the embodiment shown, a portion of the second connection traces 20 are disposed in the first interval area between the first sub-optical component area A11 and the second sub-optical component area A12 in the first optical component area A1. This first interval area does not perform a display function. Therefore, when a portion of the second connection traces 20 are disposed in the first interval area, the space of the first interval area can be fully utilized without affecting the narrowing of the borders of the first sub-optical component area A11 and the second sub-optical component area A12.
[0100] Figure 19 The diagram shows another wiring schematic of the first signal line L1 and the second signal line L2 disposed around the first optical component area A1 and the second optical component area A2. In an optional embodiment of the present invention, the first optical component area A1 includes a first sub-optical component area A11 and a second sub-optical component area A12. The first sub-optical component area A11 and the second sub-optical component area A12 are arranged along a first direction D1, and a first interval area is provided between the first sub-optical component area A11 and the second sub-optical component area A12. The display panel also includes a second winding L25 located in the first interval area. The second winding L25 is disposed on the same layer as the third line segment L23 and the fourth line segment L24, and at least part of the third line segment L23 and the fourth line segment L24 are electrically connected through the second winding L25.
[0101] Specifically, when the first optical component area A1 is provided with a first sub-optical component area A11 and a second sub-optical component area A12 arranged along the first direction D1, the first interval area between the first sub-optical component area A11 and the second sub-optical component area A12 does not need to perform display function. When there are a lot of second signal lines L2 overlapping with the first optical component area A1 along the second direction D2, the third segment L23 and the fourth segment L24 of the second signal lines L2 that are adjacent to the aforementioned first interval area can be electrically connected through the second winding L25 in the first interval area, making full use of the space of the first interval area. Similarly, it does not need to occupy or occupies less of the frame space of the first sub-optical component area A11 and the second sub-optical component area A12, which is also conducive to achieving a narrow bezel design. Furthermore, since the second winding L25 is disposed on the same layer as the third segment L23 and the fourth segment L24, it is not necessary to introduce additional second connection traces 20 for this portion of the third segment L23 and the fourth segment L24. This reduces the number of second connection traces 20 introduced into the display panel and simplifies the wiring complexity of the second connection traces 20. Optionally, the display panel may also include a portion of the second signal line L2 that directly passes through the first interval, for example, please refer to... Figure 20 , Figure 20 The diagram shows another wiring schematic of the first signal line L1 and the second signal line L2 arranged around the first optical component area A1 and the second optical component area A2.
[0102] Based on the same inventive concept, the present invention also provides a display device, please refer to [reference needed]. Figure 21 , Figure 21 The diagram shown is a structural schematic of a display device provided in an embodiment of the present invention. The display device 200 provided in this embodiment includes the display panel 100 provided in any of the above embodiments of the present invention.
[0103] It is understood that the display device 200 provided in the embodiments of the present invention can be a computer, mobile phone, tablet, or other display device with display function, and the present invention does not impose specific limitations on it. The display device provided in the embodiments of the present invention has the beneficial effects of the display panel provided in the embodiments of the present invention. For details, please refer to the specific descriptions of the display panel in the above embodiments, which will not be repeated here.
[0104] In summary, the display panel and display device provided by the present invention achieve at least the following beneficial effects:
[0105] The display panel and display device provided in the embodiments of the present invention include a first optical component area and a second optical component area arranged along a first direction. A first display area at least partially surrounds the aforementioned first optical component area and second optical component area. The first display area includes a plurality of first signal lines extending along the first direction. Along the first direction, a portion of the first signal lines overlaps with the first optical component area and the second optical component area. This portion of the first signal lines includes a first line segment and at least one second line segment, wherein the first line segment is located between the first optical component area and the second optical component area, and at least a portion of the second line segment is located on the side of the first optical component area away from the second optical component area, and / or, at least a portion of the second line segment is located on the side of the second optical component area away from the first optical component area. To achieve electrical connection between the first segment and the second segment in the first signal line, this invention introduces a first connection trace in the display panel. At least some segments of the first connection trace are disposed on different layers from the first segment and the second segment in the first signal line. When the first segment and the second segment are connected through the first connection trace, it is not necessary to wrap the trace around the bezel area surrounding the first or second optical component area. This reduces the number of traces corresponding to the bezel area surrounding the first and second optical component areas, providing compression space for the bezels of the first and second optical component areas. Therefore, it is beneficial to achieve a narrow bezel design around the optical component areas corresponding to the first and second optical component areas, which is beneficial to improving the screen ratio of the display panel and the display device.
