Description

Technical Field

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

[0002] In existing technologies, fan-out lines are provided on the bottom bezel of the display panel. One end of the fan-out line connects to the display driver chip, and the other end connects to a data line located in the display area. However, the fan-out line occupies a significant amount of space on the bottom bezel, resulting in a wider bottom bezel and affecting aesthetics. One current design solution is to place some of the fan-out lines within the display area to reduce the width of the bottom bezel. However, the fan-out lines within the display area have a certain reflectivity to ambient light, causing a difference in reflectivity between the area containing the fan-out lines and other display areas without fan-out lines. This results in uneven screen display when the screen is off. Summary of the Invention

[0003] This invention provides a display panel and a display device to solve the problem of uneven screen display caused by differences in reflectivity in the prior art.

[0004] In a first aspect, embodiments of the present invention provide a display panel, the display panel including a display area and a non-display area; the display area includes data lines and leads, and the non-display area includes pads; the data lines include a first data line, one end of the leads is coupled to the first data line and the other end is coupled to the pads; the display panel includes:

[0005] Substrate;

[0006] The driving layer is located on one side of the substrate, and the data lines and leads are located in the driving layer;

[0007] A light-emitting device located on the side of the driving layer away from the substrate;

[0008] A touch layer is located on the side of the light-emitting device away from the driving layer. The touch layer includes touch electrodes; multiple touch traces in the touch electrodes intersect and connect with each other, and these intersecting touch traces define multiple cutout areas, each cutout area overlapping with a light-emitting device; wherein,

[0009] The lead extends along the direction of the touch trace, and at least partially overlaps the touch trace in a direction perpendicular to the plane of the substrate.

[0010] Secondly, based on the same inventive concept, embodiments of the present invention also provide a display device, including the display panel provided in any embodiment of the present invention.

[0011] The display panel and display device provided in this embodiment of the invention have the following beneficial effects: By connecting the first data line to the pad 30 via a lead located within the display area, the bezel width of the non-display area where the pad is located can be reduced. Simultaneously, by setting the lead to extend along the direction of the touch trace, and by at least partially overlapping the lead with the touch trace, the overlapping lead can be shielded by the touch trace within the display area, reducing the reflection of ambient light by the lead, thereby reducing the difference in reflectivity at different locations caused by uneven lead pattern within the display area. Since the touch electrodes are arranged across the entire display area, the touch trace has a relatively uniform pattern within the display area, and no new uneven patterning problem is introduced due to the at least partial overlap between the touch trace and the lead. Therefore, this embodiment of the invention can improve the phenomenon of uneven screen display when the screen is off. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, 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 those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “a,” “the,” and “the” as used in the embodiments of this invention and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0028] To address the problems of existing technologies, embodiments of the present invention provide a display panel with leads arranged within the display area. One end of each lead is connected to a data line, and the other end is connected to a pad. This lead design reduces the occupancy of fan-out lines in the non-display area, thereby reducing the bezel width of the non-display area. Simultaneously, the leads extend along the extension direction of the touch traces in the touch layer, and the leads at least partially overlap with the touch traces. This allows the touch traces to partially shield the leads, reducing their reflection of ambient light and thus minimizing the difference in reflectivity at different locations within the display area caused by the leads, improving the problem of uneven screen display when the screen is off.

[0029] Figure 1 This is a schematic diagram of a display panel provided in an embodiment of the present invention. Figure 2 for Figure 1 Enlarged view of the Q position in the middle region. Figure 3 for Figure 2 A schematic diagram of the cross-section at the location of the tangent AA′.

[0030] like Figure 1As shown, the display panel includes a display area AA and a non-display area NA; the display area AA includes a data line 10 and a lead 20, and the non-display area NA includes multiple pads 30; the data line 10 includes a first data line 11, one end of the lead 20 is coupled to the first data line 11, and the other end is coupled to the pad 30; the data line 10 also includes a second data line 12, which is connected to the pad 30 through a fan-out line 40 located in the non-display area NA. Figure 1 The image only shows a portion of the data lines 10 within the display area AA.

[0031] Figure 2 The diagram shows a top view of the display panel. Figure 3 The diagram illustrates the film layer structure of the display panel, combined with... Figure 2 and Figure 3 The display panel includes: a substrate 00, a driving layer 01 located on one side of the substrate, a light-emitting device 50 located on the side of the driving layer 01 away from the substrate 00, and a touch layer 02 located on the side of the light-emitting device 50 away from the driving layer 01. Data lines 10 and leads 20 are located in the driving layer 01. Figure 2 and Figure 3 Data line 10 is not shown. The pixel circuit is located in the driving layer 01 and is used to drive the light-emitting device 50. The light-emitting device 50 includes a first electrode 51, a light-emitting layer 52, and a second electrode 53 stacked on one side of the driving layer 01. The first electrodes 51 of adjacent light-emitting devices 50 are isolated from each other, and the second electrodes 53 of adjacent light-emitting devices 50 are connected to each other. The light-emitting device 50 is an organic light-emitting device or an inorganic light-emitting device, and a pixel definition layer 54 is spaced between adjacent light-emitting devices 50. The touch layer 02 includes a touch electrode 60. Multiple touch traces 61 in the touch electrode 60 are interconnected and the intersecting touch traces 61 define multiple cutout areas V. One cutout area V overlaps with one light-emitting device 50. The touch traces 61 are made of metal. The lead 20 extends along the direction of the touch trace 61 and at least partially overlaps with the touch trace 61 in the direction e perpendicular to the plane of the substrate 00.

[0032] like Figure 2As shown, the display panel includes a first light-emitting device 50-1, a second light-emitting device 50-2, and a third light-emitting device 50-3, each with a different color. Multiple first light-emitting devices 50-1 are arranged in a first column along the column direction y. The second light-emitting devices 50-2 and the third light-emitting devices 50-3 are alternately arranged in a second column along the column direction y. The first and second columns are alternately arranged in the row direction x. Light-emitting devices 50-1 in adjacent first and second columns are misaligned in the row direction x. In one embodiment, the first light-emitting device 50-1 emits green light, and one of the second light-emitting devices 50-2 and the third light-emitting device 50-3 emits red light and the other emits blue light. Optionally, the second light-emitting device 50-2 emits red light and the third light-emitting device 50-3 emits blue light, with the area of ​​the third light-emitting device 50-3 being larger than the area of ​​the second light-emitting device 50-2.

[0033] like Figure 3 As shown, the display panel also includes an encapsulation layer 03, which is located on the side of the touch layer 02 near the light-emitting device 50. The encapsulation layer 03 is used to protect the light-emitting device 50 to improve its service life.

[0034] Figure 2 Only a partial shape of the touch electrode 60 is shown. Figure 4 This is a schematic diagram of another display panel provided in an embodiment of the present invention. Figure 4 The diagram illustrates the overall structure of the touch layer 02, but does not show the cutout area V in the touch electrode 60. (As shown...) Figure 4 As shown, the touch electrode 60 in the display area AA includes a first touch electrode 60-1 and a second touch electrode 60-2 whose extension directions intersect each other. The first touch electrode 60-1 and the second touch electrode 60-2 intersect to form a capacitor. The first touch electrode 60-1 and the second touch electrode 60-2 each include a plurality of sub-electrodes 60a. Figure 4 The sub-electrode 60a is illustrated in a rhombus shape.

[0035] The display panel provided in this embodiment of the invention has a first data line 11 connected to a pad 30 via a lead 20 located within the display area AA, which reduces the bezel width of the non-display area NA where the pad 30 is located. Simultaneously, the lead 20 extends along the direction of the touch trace 61, and the lead 20 at least partially overlaps with the touch trace 61. This allows the touch trace 61 within the display area AA to shield the overlapping lead 20, reducing the reflection of ambient light by the lead 20 and thus minimizing the reflectivity differences at different locations caused by the uneven pattern of the lead 20 within the display area AA. Since the touch electrode 60 is arranged across the entire surface of the display area AA, the touch trace 61 has a relatively uniform pattern within the display area AA, and the at least partial overlap between the touch trace 61 and the lead 20 does not introduce new uneven patterning problems. Therefore, this embodiment of the invention can improve the unevenness of the always-on display.

[0036] Figure 2 This is a partial top view of the display panel. The top view direction is the same as the direction perpendicular to the plane containing the substrate 00. Figure 2 The diagram illustrates the shape of the first electrode 51 in the light-emitting device 50. Figure 2 As can be seen, in the direction perpendicular to the plane of the substrate 00, the lead 20 does not overlap with the first electrode 51. Since the lead 20 is fabricated below the first electrode 51, the flatness of the first electrode 51 affects the light-emitting performance of the light-emitting device 50. In this embodiment of the invention, the lead 20 and the first electrode 51 are arranged to not overlap. When wiring the lead 20 in the display area AA, the location of the first electrode 51 is avoided, which is beneficial to the flatness of the first electrode 51 and avoids the color shift problem caused by the unevenness of the first electrode 51.

[0037] Combination Figure 2 and Figure 3 As can be seen, the pixel definition layer 54 has an opening K, and the light-emitting device 50 is located within the opening K. Figure 3 The shape of the opening K is indicated by a dashed line. The opening K exposes the first electrode 51, and the area of ​​the opening K is smaller than the area of ​​the first electrode 51. The area of ​​the opening K is also smaller than the area of ​​the cutout area V. This arrangement ensures that the touch trace 61 does not obstruct the light-emitting area of ​​the light-emitting device 50, thus ensuring the light-emitting efficiency of the light-emitting device 50.

[0038] In some implementations, such as Figure 2 As shown, in the plane perpendicular to the substrate 00, the touch trace 61 covers the lead 20. The linewidth of the lead 20 is no greater than the linewidth of the touch trace 61. In this embodiment, by covering the lead 20 with the touch trace 61, the ambient light incident on the lead 20 is essentially blocked by the touch trace 61, and the lead 20 basically does not reflect ambient light, thus eliminating the unevenness of the screen-off display caused by the uneven patterning of the lead 20. Furthermore, in this embodiment, the lead 20 does not overlap with the cutout area V, so the light penetrating the cutout area V is not blocked by the lead 20, thereby improving the light transmittance of the cutout area V. When applied in an under-display fingerprint recognition solution, this can increase the amount of light received by the under-display photosensitive device, which is beneficial for improving the accuracy of fingerprint recognition.

[0039] In some implementations... Figure 5 This is a partial schematic diagram of another display panel provided in an embodiment of the present invention. Figure 5 This is a top view of the display panel. Figure 5 This is for simplification purposes only. Figure 5 Only data line 10 and lead 20 located in the driver layer are shown. Figure 5As shown, lead 20 and the first data line 11 are coupled through a first via V1; in the direction perpendicular to the plane of the substrate, the first via V1 overlaps with the touch trace 61. This embodiment can use the touch lead 61 to block the reflection of ambient light by the first via V1, thereby improving the uneven screen display caused by the lead 20 in the display area AA.

[0040] In other implementations, Figure 6 A partial schematic diagram of another display panel provided in an embodiment of the present invention, as shown below. Figure 6 As shown, the points where the touch traces 61 intersect are the node sections 61Z. Figure 6 The top view's upward direction is parallel to the direction perpendicular to the plane containing the substrate. Figure 6 As can be seen, the first via V1 overlaps with the node 61Z in the direction perpendicular to the plane of the substrate. When the line width of the touch trace 61 is fixed, the area at the intersection of the two touch traces 61 will be relatively large. The node 61Z can completely block the first via V1, effectively preventing the reflection of ambient light by the first via V1 and improving the uneven screen display caused by the lead wire 20 in the display area AA.

[0041] in addition, Figure 5 and Figure 6 In the embodiments, the first data line 11 is shown as a straight line. In the embodiments of the present invention, the shape of the data line 10 is not limited. In order to meet the requirements of the setting position of the first via V1 between the first data line 11 and the lead wire 20, the shape of the first data line 11 can be designed. For example, the segment in the first data line 11 can be set as a broken line.

[0042] In some implementations... Figure 7 A partial schematic diagram of another display panel provided in an embodiment of the present invention, as shown below. Figure 7 As shown, the touch trace 61 includes a first touch trace 61a extending along a first direction a and a second touch trace 61b extending along a second direction b, with the first direction a and the second direction b intersecting each other; the data line 10 extends along a third direction c, which intersects both the first direction a and the second direction b, and the angles of intersection are not zero; a lead 20 includes at least one first segment 20a extending along the first direction a; in a direction perpendicular to the plane of the substrate, the first segment 20a overlaps with the first touch trace 61a. The first segment 20a and the first touch trace 61a extend in the same direction and overlap, using the first touch trace 61a to shield the first segment 20a, reducing the reflection of ambient light by the first segment 20a in the lead 20, thereby reducing the difference in reflectivity at different locations caused by the uneven pattern of the lead 20 in the display area AA.

[0043] In other implementations, Figure 8 A partial schematic diagram of another display panel provided in an embodiment of the present invention, as shown below. Figure 8 As shown, the touch trace 61 includes a first touch trace 61a extending along a first direction a and a second touch trace 61b extending along a second direction b, with the first direction a and the second direction b intersecting each other; the data line 10 extends along a third direction c, which intersects both the first direction a and the second direction b, and the angles of intersection are not zero; a lead includes at least one first segment 20a extending along the first direction a and at least one second segment 20b extending along the second direction b; the first segment 20a overlaps with the first touch trace 61a, and the second segment 20b overlaps with the second touch trace 61b. The first touch trace 61a blocks the first segment 20a, and the second touch trace 61b blocks the second segment 20b, reducing the reflection of ambient light by the first segment 20a and the second segment 20b in the lead 20, thereby reducing the difference in reflectivity at different locations caused by the uneven pattern of the lead 20 in the display area AA.

[0044] Figure 8 The diagram only illustrates the lead 20a as including a first line segment 20a and a second line segment 20b. In other embodiments, the lead 20a is a broken line with two or more corners. Figure 9 This is a partial schematic diagram of another display panel provided in an embodiment of the present invention. Figure 9 The schematic leader 20 includes at least two first line segments 20a and two second line segments 20b, and the leader 20 is a broken line including at least three corners.

[0045] In some implementations... Figure 10 A partial schematic diagram of another display panel provided in an embodiment of the present invention, as shown below. Figure 10As shown, the first data line 11 extends along the third direction c; the non-display area includes a first non-display area NA1 and a second non-display area NA2. The first non-display area NA1 is located on the side of the display area AA in the third direction c, and the second non-display area NA2 is located on the side of the display area AA in the fourth direction d. The fourth direction d intersects with the third direction c; the pad 30 is located in the first non-display area NA1. Multiple first data lines 11 include first sub-data lines 11-1 and second sub-data lines 11-2. In the fourth direction d, the distance of the first sub-data line 11-1 from the second non-display area NA2 is less than the distance of the second sub-data line 11-2 from the second non-display area NA2. Multiple leads 20 include first leads 20-1 and second leads 20-2. The first lead 20-1 is coupled to the first sub-data line 11-1, and the second lead 20-2 is coupled to the second sub-data line 11-2. A first boundary Y1 exists between the first non-display area NA1 and the display area AA. The intersection of the first lead 20-1 and the first boundary Y1 is the first point W1, and the intersection of the second lead 20-2 and the first boundary Y1 is the second point W2. The distance of the first point W1 from the second non-display area NA2 is less than the distance of the second point W2 from the second non-display area NA2. This configuration enables the data lines in the display panel to be sequentially connected to the pads 30, eliminating the need for special design of the driver chip for the display panel. The display panel provided by this embodiment has wider applicability.

[0046] In some implementations, such as Figure 10 As shown, the first non-display area NA1 includes a connecting line 70, one end of which is coupled to a lead 20, and the other end is coupled to a pad 30. The connecting line 70 includes adjacent first connecting lines 71 and second connecting lines 72, which are located on different layers, meaning they are manufactured in different processes. In this embodiment, by setting adjacent connecting lines 70 to different layers, they are manufactured in different processes, and the spacing between adjacent connecting lines 70 is not limited by process capabilities. This reduces the spacing between adjacent connecting lines 70, which is beneficial for further narrowing the bezel width of the first non-display area NA1.

[0047] In some implementations... Figure 11 for Figure 5 A schematic diagram of a cross-section at the location of the tangent line BB′. (See diagram below.) Figure 11As shown, the driving layer 01 includes a first metal layer M1 and a second metal layer M2, with the second metal layer M2 located on the side of the first metal layer M1 away from the substrate 00. Data line 10 is located on the first metal layer M1, and lead 20 is located on the second metal layer M2. Both the first metal layer M1 and the second metal layer M2 comprise titanium and aluminum. A pixel circuit is disposed in the driving layer 01, which drives the light-emitting device 50 to emit light. The pixel circuit includes multiple transistors. The semiconductor layer in the driving layer 01 forms the active layer of the transistors, and the semiconductor layer is typically located in the bottommost film layer of the driving layer 01. In existing pixel circuit layouts, data line 10 needs to be connected to the semiconductor layer via vias. Placing data line 10 on the side of lead 20 closer to the substrate 00 avoids excessive spacing between the film layer and the semiconductor layer containing data line 10, which would result in excessively large via sizes affecting wiring space.

[0048] In some implementations, such as Figure 11 As shown, a first insulating layer 81 is provided on the side of the second metal layer M2 away from the substrate 00. The first insulating layer 81 is an organic insulating layer. The first insulating layer 81 can provide a relatively flat substrate for the light-emitting device 50 fabricated on it, which is beneficial to improve the flatness of the first electrode in the light-emitting device 50 and avoid the color shift problem of the light-emitting device 50. Optionally, the second insulating layer 82 between the second metal layer M2 and the first metal layer M1 is an organic insulating layer. When the first metal layer M1 is a titanium / aluminum / titanium three-layer structure, the second insulating layer 82 can completely cover the data line 10 in the first metal layer M1, avoiding the exposure of the sloping sidewalls (formed by the patterning process) of the thicker data line 10, which would cause short circuits with the subsequently fabricated metal layers and cause defects.

[0049] In other implementations, Figure 12 A partial schematic diagram of another display panel provided in an embodiment of the present invention, as shown below. Figure 12As shown, lead 20 includes a third lead 20-3, and display area AA also includes multiple dummy lines 90. The multiple dummy lines 90 include a first dummy line 91. The first dummy line 91 is located on the same layer as lead 20, and a break is formed between the end of the first dummy line 91 near the third lead 20-3 and the third lead 20-3. In the direction perpendicular to the plane of substrate 00, touch trace 61 covers the break D. Fabricating dummy lines 90 on the same layer as lead 20 helps to ensure uniform metal patterns within the film layer where lead 20 is located, which in turn helps to achieve uniformity in the layout wiring within display area AA, ensuring that the driving performance of each pixel circuit is basically the same and guaranteeing the brightness uniformity of display area AA. To ensure insulation between the dummy line 90 and the lead line 20, a break D is required at the point where the first dummy line 91 and the third lead line 20-3 are close to each other. However, both the first dummy line 91 and the third lead line 20-3 reflect ambient light, making the break D visible. In this embodiment, the touch trace 61 covers the break D, preventing it from being visible and thus improving the visual effect of the display panel.

[0050] In some implementations, such as Figure 12 As shown, the dummy line 90 extends along the direction of the touch trace 61; in the direction perpendicular to the plane of the substrate 00, the dummy line 90 and the touch trace 61 at least partially overlap. In this embodiment, the touch trace 61 can be used to block the overlapping dummy line 90, reducing the reflection of ambient light by the dummy line 90 and thus reducing the reflectivity of the display panel.

[0051] Figure 12 The diagram only shows a dummy line 90 extending in one direction. In other embodiments, the display area AA is provided with dummy lines 90 whose extension directions intersect each other, such as a dummy line 90 extending in the first direction a and a dummy line 90 extending in the second direction b. These are not shown in the diagram here.

[0052] Based on the same inventive concept, embodiments of the present invention also provide a display device. Figure 13 This is a schematic diagram of a display device provided in an embodiment of the present invention, such as...

The display device provided in the embodiments of the present invention can be an electronic device such as a mobile phone, tablet, computer, or television.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
