[0002] The present invention relates to the field of display technology, and in particular to a display panel and a display device. [Background technology]

[0003] In the existing display device technology, display panels are mainly divided into two mainstream technologies: liquid crystal display panels and organic light-emitting display panels. Among them, the liquid crystal display panel forms an electric field that can control the deflection of liquid crystal molecules by applying voltage to the pixel electrode and the common electrode, thereby controlling the transmission of light to achieve the display function of the liquid crystal display panel; the organic self-luminous display panel uses organic electroluminescent materials. When current passes through the organic electroluminescent material, the luminescent material will emit light, thereby achieving the display function of the organic light-emitting display panel.

[0004] With the application of display technology in smart wearables and other portable electronic devices, the design of electronic products continues to pursue a smooth user experience. At the same time, there is an increasing pursuit of better visual experience. High screen-to-body ratio has become the focus of current research. [Summary of the invention]

[0025] In order to better understand the technical solution of the present invention, the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0026] It should be clear that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The terms used in the embodiments of the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. The singular forms "a", "said" and "the" used in the embodiments of the present invention and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0028] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0029] Figure 1 FIG. 1 is a partial schematic diagram of a display panel in the related art. In a display device with dual front cameras, Figure 1 As shown, the usual design is to cut off the substrate of the display panel and make a through hole K′ on the display panel. The dotted line in the figure indicates the corresponding position of the camera when assembled into a display device. Due to the setting of the through hole K′, there is a gap in the display area AA′ of the display panel. In order to achieve normal display of the display area AA′ on both sides of the through hole K′, it is necessary to electrically connect the signal lines X′ on both sides of the through hole K′ in the display area AA′. The current design is to set multiple windings S′ on the left and right sides of the through hole K′ as shown in the figure. The multiple windings S′ occupy a large space around the through hole K′ to form a border area B′ surrounding the through hole K′. The width of the border area B′ is relatively wide, which affects the screen-to-body ratio, resulting in poor visual effects of the display panel.

[0030] Based on this, the present invention provides a display panel. By changing the setting method of through holes and connecting lines, at least two adjacent through holes are set in the display panel, and at least part of the connecting lines are set between the two through holes, thereby reducing the number of connecting lines set between the through holes and the display area, and realizing the dispersed setting of the connecting lines, which is beneficial to narrowing the width of the internal frame at the position of the through holes and improving the screen-to-body ratio.

[0031] Figure 2 A partial schematic diagram of a display panel provided by an embodiment of the present invention. Figure 2 As shown, the display panel includes a display area AA and a non-display area BA, and the display area AA surrounds the non-display area BA; the non-display area BA has at least two through holes K penetrating the display panel, and the through holes K are arranged along the second direction y. Optionally, when assembled into a display device, the image acquisition device and / or the sound generating device in the display device overlap with the through hole K. For example, in a display device with two front cameras, the display panel provided by the present invention reserves a through hole for each of the two cameras for light transmission, that is, one camera corresponds to one through hole. The non-display area BA also includes a first non-display area BA1 located between the two through holes K. It should be noted that the present invention does not limit the shape of the through hole K. The through hole K can be circular, triangular or square, and can be selected according to specific design requirements in practice. Figure 1 Similarly, the shape of the first non-display area BA1 between the two through holes K can also be adaptively adjusted according to the shape of the through holes.

[0032] The display panel also includes a plurality of first signal lines extending along a first direction x, the first signal lines are signal lines for driving pixels in the display area AA to display, wherein the first direction x is perpendicular to the second direction y, the first signal lines include a first A signal line X1a and a first B signal line X1b, the first B signal line X1b is extended through the display area AA, that is, the first B signal line X1b is a signal line conventionally set in the display area AA. The first A signal line X1a includes at least two first A sub-signal lines Z and a connecting line M, the connecting line M is used to connect the two first A sub-signal lines Z, that is, the first A signal line X1a is a signal line that needs special routing design after the through hole K is set, after the through hole K is set in the display panel, the first A signal line X1a is terminated at the position where the through hole K is located, and the first A signal line X1a is divided into the first A sub-signal lines Z located on both sides of the through hole K and the connecting line M connecting the two first A sub-signal lines Z. The connection lines M include first connection lines M1 , wherein the first Z signal line Z is located in the display area AA, and the first connection lines M1 is located in the first non-display area BA1 .

[0033] The display panel provided by the present invention has a display area surrounding a non-display area, that is, a non-display area for non-display is provided inside the display area, wherein the non-display area at least includes a through hole and a first non-display area, and the through hole is a reserved module setting area. When assembled into a display device, an image acquisition device and / or a sound generating device can be provided at a position corresponding to the through hole. When forming the through hole, the display panel needs to be cut, and the base substrate and the film layers such as the array layer and the display layer above the base substrate are cut off. The first non-display area between two adjacent through holes is equivalent to a part of the wiring area in the non-display area. Figure 2 As shown in FIG. 1 , the non-display area also includes a second non-display area BA2 located on the side of the through hole K away from the first non-display area BA1 in the second direction y. The second non-display area BA2 is at least partially arranged around the through hole K. The second non-display area BA2 is equivalent to the internal frame between the through hole K and the display area AA. The extension direction of the first signal line in the display panel is perpendicular to the arrangement direction of the through hole. Due to the arrangement of the through hole, part of the first signal line (i.e., the first A signal line) in the display area will be terminated at the position of the through hole. In order to enable the pixels located on both sides of the through hole in the first direction to display normally, a connecting line is arranged in the non-display area. The connecting line is used to connect the two first A signal lines located on both sides of the non-display area in the first direction.

[0034] In the display panel of the related art, a through hole is usually reserved for two or more modules. Figure 1As shown in the diagram, it is necessary to arrange multiple winding wires S' (corresponding to the connecting wire M in the embodiment of the present invention) around the through hole on both sides of the through hole, which occupies a large space, resulting in a large non-display area between the through hole and the display area (corresponding to the second non-display area BA2 in the embodiment of the present invention), which will occupy the area of ​​the display area accordingly and reduce the display luminous area. The display panel provided by the present invention is provided with two or more through holes, and a module setting area can be reserved for a module, that is, one module corresponds to one through hole. The present invention retains the substrate between two adjacent through holes, and then a wiring (such as the first connecting wire in the present invention) can be arranged on the substrate to form a first non-display area, that is, the first connecting wire is arranged between two adjacent through holes. Optionally, in the display panel provided by the embodiment of the present invention, all the connecting wires can be arranged in the first non-display area, and the through hole passes through the display panel, so the through hole cannot be displayed, that is, the design of the present invention is to arrange the connecting wire between two non-displaying through holes. When displaying, the human eye is not sensitive to the non-display area between the two non-displaying through holes, so the connecting wire is arranged in the first non-display area, which does not affect the overall visual effect. The present invention arranges at least part of the connecting wires to be routed between two adjacent through holes, which can reduce the number of connecting wires arranged between the through holes and the display area, save space between the through holes and the display area in the second direction, narrow the internal frame of the display panel, and is beneficial to increasing the screen-to-body ratio and improving the display effect of the display panel.

[0035] Optionally, in the display panel provided by the embodiment of the present invention, the connecting wire and the first signal wire are made of the same layer and the same material, that is, the connecting wire and the first signal wire can be manufactured in the same process, which can simplify the process.

[0036] For further information, please refer to Figure 2As shown, the non-display area BA also includes a second non-display area BA2 located on the side of the through hole K away from the first non-display area BA1, and the second non-display area BA2 at least partially surrounds the through hole K; the second non-display area BA2 is equivalent to the internal frame between the through hole K and the display area AA. The connecting line M also includes a second connecting line M2, and the second connecting line M2 is located in the second non-display area BA2. In the display panel provided by this embodiment, the connecting line includes a first connecting line located in the first non-display area and a second connecting line located in the second non-display area, which is equivalent to dispersing the connecting lines, which can reduce the number of connecting lines set in the second non-display area and save space in the second non-display area. In addition, in this embodiment, connecting lines are arranged in both the first non-display area and the second non-display area, which can balance the number of lines in the first non-display area and the second non-display area, and will not significantly increase the spacing distance between the two through holes, and will not affect the visual effect. At the same time, it will not significantly increase the distance between the through hole and the display area (i.e., the second non-display area) in the second direction, which is conducive to narrowing the internal frame of the display panel, increasing the light-emitting area of ​​the display area, and can improve the screen-to-body ratio and enhance the display effect of the display panel.

[0037] In some optional embodiments, the display panel provided by the embodiment of the present invention can be configured such that all connecting lines are arranged between two adjacent through holes for routing, that is, no connecting lines are arranged in the second non-display area, thereby maximizing the space saving in the second non-display area. This embodiment is no longer illustrated in the drawings.

[0038] In one embodiment, continue to refer to Figure 2 As shown, the non-display area BA includes two second non-display areas BA2, and the number of second connection lines M2 respectively set in the two second non-display areas BA2 is equal. In this embodiment, the first connection line located in the first non-display area is first included, and some of the connection lines are set to be routed between two adjacent through holes, which can reduce the number of second connection lines set in the second non-display area, save space in the second non-display area, and help narrow the internal frame of the display panel. In addition, the number of second connection lines set in the two second non-display areas is equal, ensuring that the space occupied by the connection lines in the two second non-display areas is the same, and the size of the two second non-display areas can be ensured to be consistent, so that the width of the internal frame on both sides of the through hole is consistent, which can enhance the visual effect of the display panel.

[0039] In the display panel provided by the present invention, the first connecting line is routed between two adjacent through holes, and there may be multiple situations for the setting of the first connecting line. For example, the first connecting line may be consistent with the extension direction of the conventional first signal line in the display area, or the first connecting line may be routed around the edge of the through hole in the first non-display area. When the first connecting line is routed around the edge of the through hole, it may cause the total length of the first A signal line to differ from the total length of the conventionally set first B signal line, and then the difference in resistance leads to a voltage drop difference when transmitting the signal, and finally leads to a difference in the pixel display driven by the first A signal line and the first B signal line. The inventor comprehensively considered the above situation, and on the basis of setting the first connecting line to route between two adjacent through holes to reduce the internal frame of the display panel and increase the screen-to-body ratio, further designed the first connecting line in the display panel and its corresponding line width. The following embodiments will illustrate the specific situation. It should be noted that the line width involved in the following embodiments refers to the width of the line, that is, the width in the direction perpendicular to the extension of the line. When the line is a curve, its line width can be calculated according to a unified calculation rule. For example, after the curve is enlarged by a certain multiple, the curve approaches a straight line, and the width of the enlarged straight line is measured as the line width of the original curve.

[0040] In one embodiment, Figure 3 A partial schematic diagram of an optional implementation of a display panel provided in an embodiment of the present invention. Figure 3 As shown, the first connection line M1 includes a first B connection line M1b, the first B connection line M1b and the first A signal line Z have the same extension direction, and the line width d1 of the first B connection line M1b is equal to the line width d2 of the first B signal line X1b. Figure 3 The display panel also illustrates a case where the display panel includes a second connecting line M2. Optionally, the display panel may not be provided with a second connecting line. If the extension direction of the first B connecting line is the same as the extension direction of the first A sub-signal line, then the first B connecting line is the same as the extension direction of the first B signal line in the display panel, and the total length of the first A signal line and the first B signal line formed by the first A sub-signal line electrically connected by the first B connecting line is substantially the same. In this embodiment, the line width of the first B connecting line is set equal to the line width of the first B signal line, so that the resistance of the first A signal line formed by the first B connecting line and the first A sub-signal line can be ensured to be substantially equal to the resistance of the first B signal line, thereby ensuring that the voltage drop generated when the first A signal line and the first B signal line transmit signals is substantially the same, thereby ensuring that the display brightness of the pixels driven by the first A signal line and the first B signal line are consistent.

[0041] In another embodiment, the first connecting line further includes a first A connecting line, the first A connecting line is at least partially arranged around the through hole, and the line width of at least part of the line segment of the first A connecting line is greater than the line width of the first B signal line. Figure 4A partial schematic diagram of another optional implementation of a display panel provided in an embodiment of the present invention. Figure 4 As shown, taking the example that the line width of all line segments of the first A connecting line M1a is greater than the line width of the first B signal line X1b, the first A connecting line M1a is at least partially arranged around the through hole K. Among them, the line width of the first A connecting line M1a is d3, and the line width of the first B signal line X1b is d2, and d3>d2. In this embodiment, the first A connecting line is at least partially arranged around the through hole, resulting in a larger total length of the first A signal line formed by the first A connecting line and the first A sub-signal line, that is, the total length of the first A signal line is greater than the total length of the first B signal line. If the line width of the first A connecting line is not adjusted, the resistance of the first A signal line where it is located will increase. In the embodiment of the present invention, the line width of at least part of the line segments of the first A connecting line is greater than the line width of the first B signal line. According to the resistance law: R=ρL / S, wherein ρ is the resistivity of the material of the wire, L is the length of the wire, S is the cross-sectional area of ​​the wire, and R is the resistance value. By increasing the line width of at least part of the line segment of the first A connecting line, the resistance of the first A connecting line per unit length is reduced, thereby balancing the resistance difference between the first A signal line and the first B signal line, ensuring that the resistance of the first A signal line formed by the first A connecting line and the first A sub-signal line is roughly equal to the resistance of the first B signal line, thereby ensuring that the voltage drops generated when the first A signal line and the first B signal line transmit signals are roughly the same, thereby ensuring that the pixels driven by the first A signal line and the first B signal line each display consistent brightness.

[0042] Optionally, the line width of only a portion of the first A connecting line may be adjusted to compensate for the resistance difference between the first A signal line and the first B signal line caused by the routing direction setting of the first A connecting line.

[0043] In another embodiment, Figure 5 A partial schematic diagram of another optional implementation of a display panel provided in an embodiment of the present invention. Figure 5As shown, in the display panel, there may be a first A connection line M1a and a first B connection line M1b in the first non-display area BA1, the first B connection line M1b and the first A signal line Z extend in the same direction, and the first A connection line M1a is at least partially disposed around the through hole K. The length of the first A connection line M1a is greater than the length of the first B connection line M1b. The figure does not show the line width of the first A connecting line M1a and the first B connecting line M1b. Optionally, the line width of the first B connecting line M1b can be set equal to the line width of the first B signal line X1b, which can ensure that the resistance of the first A signal line formed by the first B connecting line M1b and the first A sub-signal line Z is roughly equal to the resistance of the first B signal line; the line width of the first A connecting line M1a is set to be greater than the line width of the first B signal line X1b, and the line width of at least part of the line segment of the first A connecting line M1a is increased to reduce the resistance of the first A connecting line M1a per unit length, thereby balancing the resistance difference between the first A signal line and the first B signal line, and ensuring that the resistance of the first A signal line formed by the first A connecting line and the first A sub-signal line is roughly equal to the resistance of the first B signal line. This embodiment can ensure that the voltage drop generated by the first A signal line and the first B signal line when transmitting signals is roughly the same, thereby ensuring that the pixels driven by the first A signal line and the first B signal line display brightness are consistent.

[0044] Furthermore, the display panel also includes a second signal line extending along the second direction and insulated and overlapped with the first signal line, and a coupling capacitor will exist at the position where the first signal line and the second signal line are insulated and overlapped. The first connecting line is a partial line segment of the first signal line. If the line width of the first connecting line is adjusted in the first non-display area, it will affect the coupling capacitor where the first connecting line and the second signal line are insulated and overlapped. The inventor continues to propose solutions for the two connecting line setting methods of the first A connecting line and the first B connecting line to compensate for the capacitance difference and avoid the capacitance difference causing the pixel display difference driven by the first A signal line and the first B signal line.

[0045] In one embodiment, Figure 6 A partial schematic diagram of another optional implementation of a display panel provided in an embodiment of the present invention. Figure 6As shown, the display panel further includes a second signal line X2 extending along the second direction y and insulated and overlapped with the first signal line X1. In the first non-display area BA1, the first connection line M1 is insulated and overlapped with the second signal line X2. The first connection line M1 includes a first B connection line M1b. The first B connection line M1b and the first A signal line Z extend in the same direction. The line width d1 of the first B connection line M1b is equal to the line width d2 of the first B signal line X1b. The second signal line X2 includes a first subsection F1 overlapping with the first B signal line X1b and a second subsection F2 overlapping with the first B connection line M1b. The line width d4 of the first subsection F1 is equal to the line width d5 ​​of the second subsection F2. In this embodiment, the extension direction of the first B connecting line is the same as the extension direction of the first A signal line, and the line width of the first B connecting line is equal to the line width of the first B signal line, so that the resistance of the first A signal line formed by the first B connecting line and the first A signal line is roughly equal to the resistance of the first B signal line, thereby ensuring that the voltage drop generated when the first A signal line and the first B signal line transmit signals is roughly the same. Further, the line width of the part of the second signal line that overlaps with the first B connecting line is equal to the line width of the part of the second signal line that overlaps with the first B signal line, then the coupling capacitance generated by the insulation overlap of the first B connecting line and the second signal line is roughly the same as the coupling capacitance generated by the insulation overlap of the first B signal line and the second signal line, thereby further ensuring that the display brightness of the pixels driven by the first A signal line and the first B signal line are consistent, thereby ensuring display uniformity.

[0046] In one embodiment, Figure 7 A partial schematic diagram of another optional implementation of a display panel provided in an embodiment of the present invention. Figure 7As shown, the display panel further includes a second signal line X2 extending along the second direction y and insulated and overlapped with the first signal line X1. In the first non-display area BA1, the first connection line M1 is insulated and overlapped with the second signal line X2; the first connection line M1 includes a first A connection line M1a, the line width of the first A connection line M1a is d3, and the line width of the first B signal line X1b is d2, d3>d2. The second signal line X2 includes a first subsection F1 overlapping with the first B signal line X1b and a third subsection F3 overlapping with the first A connection line M1a, and the line width d6 of the third subsection F3 is less than the line width d4 of the first subsection F1. In this embodiment, the line width of the first A connection line is first set to be larger than the line width of the first B signal line to reduce the resistance of the first A connection line per unit length, thereby balancing the resistance difference between the first A signal line and the first B signal line, and ensuring that the resistance of the first A signal line formed by the first A connection line and the first A sub-signal line is substantially equal to the resistance of the first B signal line. As the line width of the first A connecting line increases, when the second signal line is not changed in design, the insulation overlap area between the first A connecting line and the second signal line increases, and the generated coupling capacitance increases. In the embodiment of the present invention, the line width of the third division is further set to be smaller than the line width of the first division, and the line width of the insulation overlap portion of the second signal line and the first A connecting line is reduced to ensure that the insulation overlap area of ​​the first A connecting line and the second signal line remains approximately unchanged, thereby ensuring that the coupling capacitance generated by the insulation overlap of the first A connecting line and the second signal line remains approximately unchanged. This implementation can ensure that the resistance of the first A signal line is approximately equal to the resistance of the first B signal line, and at the same time ensure that the coupling capacitance between the first A signal line and the second signal line is approximately the same as the coupling capacitance between the first B signal line and the second signal line, thereby ensuring that the display brightness of the pixels driven by the first A signal line and the first B signal line are consistent, thereby ensuring display uniformity.

[0047] In one embodiment, Figure 8 A partial schematic diagram of another optional implementation of a display panel provided in an embodiment of the present invention. Figure 8As shown, the display panel further includes a second signal line X2 extending along the second direction y and insulated and overlapped with the first signal line X1. In the first non-display area BA1, the first connecting line M1 is insulated and overlapped with the second signal line X2; the first connecting line M1 includes a first A connecting line M1a, the line width of the first A connecting line M1a is d3, the line width of the first B signal line X1b is d2, and d3>d2. The first A connecting line M1a includes a first sub-segment D1 overlapping with the second signal line X2, and a second sub-segment D2 not overlapping with the second signal line X2; wherein the line width d7 of the first sub-segment D1 is equal to the line width d2 of the first B signal line X1b, and the line width d8 of the second sub-segment D2 is greater than the line width d2 of the first B signal line X1b. Since the first A connecting line is at least partially arranged around the through hole, the total length of the first A signal line where the first A connecting line is located is greater than the total length of the first B signal line, and there is a difference in resistance between the first A signal line and the first B signal line. In this embodiment, the line width of part of the first A connecting line (that is, the second sub-line segment) is first increased to compensate for the resistance difference between the first A signal line and the first B signal line, so as to ensure that the resistance of the first A signal line is substantially the same as the resistance of the first B signal line. At the same time, the line width of the part of the line segment (that is, the first sub-line segment) where the first A connecting line overlaps with the second signal line is set unchanged to ensure that the overlapping area of ​​the first A connecting line and the second signal line remains unchanged, so that the coupling capacitance between the first A signal line and the second signal line is substantially the same as the coupling capacitance between the first B signal line and the second signal line, thereby ensuring that the display brightness of the pixels driven by the first A signal line and the first B signal line are consistent, thereby ensuring display uniformity.

[0053] In one embodiment, the first signal line is a power signal line, and the second signal line is a scan line or a reset signal line. In another embodiment, the first signal line is a reset signal line, and the second signal line is a data line or a power signal line.

[0054] In some optional embodiments, Fig.12 A partial schematic diagram of another optional implementation of a display panel provided in an embodiment of the present invention. Fig.12 As shown, in the second direction y, the minimum distance H between the edges of two adjacent through holes K is 0.1 mm≤H≤3 mm. Fig.12 Only the shape of the through hole K is circular for illustration. In the present invention, the first connecting line is set between two adjacent through holes. In the embodiment of the present invention, H≥0.1mm is set to ensure that there is a certain space between the two through holes in the second direction to be used to set the first connecting line. At the same time, H≤3mm is set to ensure that the spacing distance between the two through holes in the second direction is small enough. For example, when H=3mm, although a small number of pixels can be placed in the area between the two through holes, the inventor considers that due to the small area of ​​the area, even after the pixels are set, the complete graphics (such as small area of ​​power graphics, data signal graphics, etc. that can serve as identification) cannot be displayed. Therefore, the inventor makes reasonable use of this area, and by setting at least part of the connecting line between the two through holes, the area of ​​the non-display area between the through hole and the display area in the second direction is saved, so as to reduce the internal frame of the display panel and improve the display visual effect.
