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] Currently, narrow bezels have become a major trend in the display industry. In display products with touch functionality, a large number of touch leads need to be placed in the non-display area. These touch leads occupy a significant amount of space in the non-display area, which is detrimental to narrowing the bezel. Summary of the Invention

[0003] This invention provides a display panel and a display device to solve the technical problem of narrowing the bezel.

[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 including touch electrodes, the touch electrodes including a first touch electrode extending along a first direction and a second touch electrode extending along a second direction, the first direction and the second direction intersecting;

[0005] The non-display area includes a first non-display area, which is located on one side of the display area in the second direction. The first non-display area includes multiple touch terminals.

[0006] The display panel also includes touch leads, which include a first touch lead and a second touch lead. One end of the first touch lead is electrically connected to a first touch electrode and the other end is electrically connected to a touch terminal. One end of the second touch lead is electrically connected to a second touch electrode and the other end is electrically connected to a touch terminal.

[0007] The display area includes a wiring area, which is located at the corner of the display area and is adjacent to the first non-display area; wherein, at least a portion of a first touch lead is located in the wiring area.

[0008] 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.

[0009] The display panel and display device provided in this embodiment of the invention have the following beneficial effects: A wiring area is provided in the display area, located at a corner of the display area and adjacent to a first non-display area at the bottom bezel of the display panel. A portion of at least one first touch lead is disposed in the wiring area. After being led out from one end of the first touch electrode in the first direction, the at least one first touch lead first runs within the non-display areas on the left and right sides of the display area, then enters the wiring area, and finally connects to the touch terminal via the wiring area into the first non-display area. This arrangement reduces the space occupied by the first touch lead in the first non-display area in the second direction, saving space in the first non-display area in the second direction and facilitating a narrower bezel.

[0021] 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.

[0022] 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.

[0023] Figure 1 This is a schematic diagram of a display panel in the prior art. For example... Figure 1 As shown, the display panel includes a display area AA and a non-display area NA. The display area AA includes a first touch electrode 01 extending in a first direction x and a second touch electrode 02 extending in a second direction y. A touch driving structure 03 is disposed in the first non-display area NA1 of the lower bezel of the display panel. The first touch electrode 01 is connected to the touch driving structure 03 through a first touch lead 04 wired in the non-display area NA. The second touch electrode 02 is connected to the touch driving structure 03 through a second touch lead 05 wired in the non-display area NA. The first touch lead 04 is led out from the left or right side of the first touch electrode 01, extends in the non-display area NA of the left or right bezel, and then extends into the first non-display area NA1, as shown. Figure 1 As illustrated in the diagram, at the bottom bezel position, the first touch lead 04 extends first along the first direction x and then along the second direction y to connect to the touch driving structure 03. Among the multiple first touch leads 04 arranged side by side in the first non-display area NA1, the portion along the first direction x restricts the narrowing of the bottom bezel.

[0024] In one existing technology, two metal layers are used to fabricate the touch leads. The touch leads on the upper and lower metal layers are staggered, which reduces the spacing between the touch leads, thereby reducing the space occupied by the touch leads in the non-display area and narrowing the bezel. However, once the manufacturing process reaches its limit, the bezel in the non-display area cannot be further compressed.

[0025] To address the problems existing in the prior art, this invention provides a display panel that designs the wiring method for the touch leads at the lower corner of the display panel, routing at least a portion of the touch leads in the display area, thereby reducing the space occupied by the touch leads on the lower bezel and achieving the goal of narrowing the lower bezel.

[0026] Figure 2 This is a schematic diagram of a display panel provided in an embodiment of the present invention, such as... Figure 2As shown, the display panel includes a display area AA and a non-display area NA. The display area AA includes touch electrodes 10, which include a first touch electrode 11 extending along a first direction x and a second touch electrode 12 extending along a second direction y, the first direction x and the second direction y intersecting. Optionally, one of the first touch electrode 11 and the second touch electrode 12 is a touch driving electrode and the other is a touch sensing electrode. A touch driving signal is provided to the touch driving electrode. There is a touch capacitance between the first touch electrode 11 and the second touch electrode 12. When a finger presses the display area AA, the touch capacitance at the finger pressing position will change. The finger pressing position is determined based on the sensing signal returned by the touch sensing electrode, thus realizing touch detection.

[0027] The non-display area NA includes a first non-display area NA1, which is located on one side of the display area AA in the second direction y, and is situated at the bottom bezel of the display panel. The first non-display area NA1 includes multiple touch terminals 20; touch electrodes 10 need to be connected to the touch terminals 20. Optionally, the display panel also includes a touch driving structure, which is bonded to the touch terminals. The touch driving structure provides touch driving signals to the touch driving electrodes through the touch terminals 20 and receives sensing signals returned by the touch sensing electrodes through the touch terminals 20. The touch driving structure is also used to process the touch sensing signals for touch detection.

[0028] like Figure 2 As shown, the display panel also includes touch leads 30, which include a first touch lead 31 and a second touch lead 32. One end of the first touch lead 31 is electrically connected to the first touch electrode 11 and the other end is electrically connected to the touch terminal 20. One end of the second touch lead 32 is electrically connected to the second touch electrode 12 and the other end is electrically connected to the touch terminal 20.

[0029] The display area AA includes a wiring area AA1, which is located at a corner of the display area AA and is adjacent to the first non-display area NA1. At least one segment of a first touch lead 31 is located within the wiring area AA1. The wiring area AA1 is located at the lower corner of the display area AA. The first touch lead 31, originating from one end of the first touch electrode 31 in the first direction x, can be routed within the wiring area AA and then enter the first non-display area AA1. The first touch lead 31 originating from the wiring area AA1 extends along the second direction y and connects to the touch terminal 20.

[0030] The display panel provided in this embodiment of the invention includes a wiring area AA1 within the display area AA. The wiring area AA1 is located at a corner of the display area AA and adjacent to a first non-display area NA1 at the bottom edge of the display panel. A portion of at least one first touch lead 31 is disposed within the wiring area AA1. After being led out from one end of the first touch electrode 11 in the first direction x, the first touch lead 31 first runs within the non-display areas NA on the left and right sides of the display area AA, then enters the wiring area AA1, and finally connects to the touch terminal 20 via the wiring area AA1 into the first non-display area NA1. This arrangement reduces the space occupied by the first touch lead 31 in the first non-display area NA1 in the second direction y, saving space in the first non-display area NA1 in the second direction y, which is beneficial for narrowing the bezel.

[0031] Figure 2 The diagram illustrates that wiring areas AA1 are located at the left and right lower corners of the display area AA. In some embodiments, wiring areas AA1 may be located at only one lower corner of the display area AA, depending on design requirements. Additionally, Figure 2 The illustration shows that the corner of display area AA is a right-angle corner. In some embodiments, display area AA has an arc-shaped corner. When the lower corner of display area AA near the first non-display area NA1 is an arc-shaped corner, the same method can be used. Figure 2 The design includes a wiring area AA1 at the curved corner, which will not be shown in the attached diagram.

[0032] like Figure 2 As shown, the wiring area AA1 does not overlap with the touch electrode 10, meaning that the touch electrode 10 is not placed at the location of the wiring area AA1. Therefore, the touch lead 30 in the wiring area AA1 can be fabricated in the same layer as the touch electrode 10, without the need to add an additional conductive layer to fabricate the touch lead 30 in the wiring area AA1.

[0033] In some implementations, such as Figure 2 As shown, the second touch lead 32 extends from one end of the second touch electrode 12 in the second direction y to the first non-display area NA1. After the wiring area AA1 is set in the display area AA, the wiring area AA1 is adjacent to at least one second touch electrode 12 in the second direction y. To simplify the wiring of the second touch lead 32, at least one segment of the second touch lead 32 can be located in the wiring area AA1. At least one second touch lead 32 enters the first non-display area NA1 through the wiring area AA1. The second touch lead 32 is wired according to the routing outline of the first touch lead 31 in the wiring area AA1. The second touch lead 32 and the first touch lead 31 are wired side by side in the wiring area AA1 to avoid the touch leads crossing and increase the wiring complexity.

[0034] In some implementations... Figure 3 This is a schematic diagram of another display panel provided in an embodiment of the present invention. Figure 4 for Figure 3 A schematic diagram of a cross-section at the position of the midtangent line A-A'. (Combined with...) Figure 3 and Figure 4 Looking at the wiring area AA1, it also includes a protective line 40; within the display area AA, the protective line 40 is on the same layer as the touch lead 30, and the protective line 40 is located between the touch lead 30 and the touch electrode 10. Figure 4 As can be seen, the display panel includes a substrate 50 and a first conductive layer 51. The first touch electrode 11, the second touch electrode 12, and the protective line 40 and touch lead 30 within the wiring area AA1 are all located on the first conductive layer 51. Optionally, the first conductive layer 51 may include a metallic material. Optionally, the protective line 40 is connected to a fixed potential. The protective line 40 serves to protect the touch electrode 10 and the touch lead 30, preventing signal crosstalk between them and improving touch detection accuracy.

[0035] Optionally, a protective line is provided between adjacent first touch leads 31 and second touch leads 32 to prevent signal crosstalk between the first touch leads 31 and the second touch leads 32.

[0036] like Figure 4 As shown, the display panel also includes a second conductive layer 52, which comprises a metallic material and is used to fabricate the connection structure in the second touch electrode 12. The connection structure will be described in specific embodiments related to the structure of the touch electrode.

[0037] In some implementations, such as Figure 2 As shown, within the wiring area AA1, the spacing between two adjacent touch leads 30 (i.e., two adjacent first touch leads 31, or adjacent first touch leads 31 and second touch leads 32) is d1, where 100μm≤d1≤150μm. The spacing d1 is a safe distance between two touch leads 30 within the wiring area AA1, ensuring mutual insulation between adjacent touch leads 30. Simultaneously, it minimizes the space occupied by the wiring area AA1 in the second direction y when the number of touch leads 30 within the wiring area AA1 is fixed, thereby reducing the impact on touch performance.

[0038] In some implementations, such as Figure 2As shown, the non-display area NA also includes a second non-display area NA2. In the first direction x, the second non-display area NA2 is located on one side of the display area AA. The first non-display area NA1 and the second non-display area NA2 are connected around the lower corner of the display area AA. That is, the wiring area AA1 is adjacent to the second non-display area NA2 in the first direction x, and the wiring area AA2 is adjacent to the first non-display area NA1 in the second direction y. At least one first touch lead 31 includes a first segment 31a, a second segment 31b, and a third segment 31c. The second segment 31b connects the first segment 31a and the third segment 31c. The first segment 31a is located in the second non-display area NA2, the second segment 31b is located in the wiring area AA1, and the third segment 31c is located in the first non-display area NA1. The second segment 31b within the wiring area AA1 includes at least a sub-segment extending along the first direction x and a sub-segment extending along the second direction y. The second segment 31b is a broken line, which changes the routing direction of the first touch lead 31. Therefore, the third segment 31c extending from the wiring area AA1 can directly extend along the second direction y and connect to the touch terminal 20. This arrangement reduces the space occupied by the portion of the first touch lead 31 extending along the first direction x in the first non-display area AA1, thereby narrowing the width of the first non-display area AA1.

[0039] In some implementations... Figure 5 This is a partial schematic diagram of a display panel provided in an embodiment of the present invention, such as... Figure 5 As shown, the first touch electrode 11 includes a plurality of first sub-electrodes 111 arranged in a first direction x, and two adjacent first sub-electrodes 111 are connected by a first connecting portion 112. The second touch electrode 12 includes a plurality of second sub-electrodes 121 arranged in a second direction y, and two adjacent second sub-electrodes 121 are connected by a second connecting portion 122. The first connecting portion 112 and the second connecting portion 122 are insulated from each other, and one of the first connecting portion 112 and the second connecting portion 122 is on the same layer as the first sub-electrodes 111 and the second sub-electrodes 121. Figure 5 As illustrated, the first connecting portion 112 is on the same layer as the first sub-electrode 111 and the second sub-electrode 121. Figure 4 As can be seen, the first connecting part 112 is located in the first conductive layer 51, and the second connecting part 122 is electrically connected to the second sub-electrode 121 through a via. The second connecting part 122 is located in the second conductive layer 52.

[0040] like Figure 5 As shown, the display panel includes multiple touch units 60. Figure 5The position circled in the middle is a touch unit 60. The touch unit 60 includes a first electrode block 11-1 and a second electrode block 12-1. The first electrode block 11-1 belongs to the first touch electrode 11, and the second electrode block 12-1 belongs to the second touch electrode 12. Figure 5 In this embodiment, the first electrode block 11-1 and the second electrode block 12-1 are approximately triangular in shape, and the two first electrode blocks 11-1 and the two second electrode blocks 12-1 are pieced together to form an approximately rectangular touch unit 60. The area of ​​the touch unit 60 is the sum of the areas of the first electrode blocks 11-1 and the second electrode blocks 12-1 within its region. A capacitance exists between the first touch electrode 11 and the second touch electrode 12 in the touch unit 60, and the magnitude of the capacitance affects the touch performance of the touch unit 60. It can be understood that... Figure 5 The diagram illustrates the division of the touch unit 60, where the entire display area AA can be divided into multiple touch units 60.

[0041] In this embodiment of the invention, the ratio of the area of ​​the first electrode block 11-1 and the second electrode block 12-1 in the touch unit 60 is a fixed value. This setting is beneficial to make the touch performance of each touch unit 60 basically the same, simplify the processing of touch sensing signals, and improve the accuracy of touch detection.

[0042] In some implementations, such as Figure 5 As shown, the first electrode block 11-1 and the second electrode block 12-1 in the touch unit 60 have basically the same area, which can ensure that the capacitance in each touch unit 60 in the display area AA is basically the same, so the touch performance of each touch unit 60 is basically the same.

[0043] In some implementations... Figure 6 This is another schematic diagram of a display panel provided in an embodiment of the present invention, such as... Figure 6As shown, the display area AA includes multiple touch units 60 arranged in an array. Each touch unit 60 includes a first touch unit 61 and a second touch unit 62. In the second direction y, the second touch unit 62 is adjacent to the wiring area AA1, and the first touch unit 61 is located on the side of the second touch unit 62 furthest from the wiring area AA1. The area of ​​the first touch unit 61 is S1, and the area of ​​the second touch unit 62 is S2, where 0.75*S1≤S2≤1.25*S1. In general designs, to ensure consistent touch performance at all locations within the display area AA and to facilitate the detection of touch operations, the areas of each touch unit 60 within the display area AA are typically set to be approximately the same. In this embodiment of the invention, a wiring area AA1 is provided at the lower corner of the display area AA, and at least one segment of the first touch lead 31 is provided to run within the wiring area AA1. The wiring area AA1 occupies a certain width in the second direction y. The wiring area AA1 occupies the space for setting the touch electrode, so the touch unit 60 in the display area AA needs to be designed in combination with the length of the wiring area AA1 in the second direction y.

[0044] In some implementations, although the wiring area AA1 occupies a certain width in the second direction y, when designed in conjunction with the length of the display area AA in the second direction y and the area size required by the touch unit 60 to meet the touch performance requirements, it is possible to achieve that the second touch unit 62 adjacent to the wiring area AA1 in the second direction y has a basically the same area as other touch units 60 in the display area AA, that is, S1 = S2. At this time, the touch performance of the second touch unit 62 is basically the same as that of the first touch unit 61. The setting of the wiring area AA1 does not affect the touch performance while reducing the bezel.

[0045] In other embodiments, when designing the touch unit 60 in conjunction with the length of the display area AA in the second direction y and the area size required for the touch unit 60 to meet its touch performance requirements, S1 ≠ S2. When S1 is greater than S2, 0.75*S1≤S2, meaning the area of ​​the second touch unit 62 is not less than 75% of the area of ​​the first touch unit 61, and the ratio of the areas of the first electrode block 11-1 and the second electrode block 12-1 within the second touch unit 62 is equal to the ratio of the areas of the first electrode block 11-1 and the second electrode block 12-1 within the first touch unit 61; when S2 is greater than S1, S2≤1.25*S1 is set. This setting can reduce the capacitance difference between the second touch unit 62 and the first touch unit 61, and the capacitance difference can be compensated by subsequent processing of the touch sensing signal. This allows for reducing the bezel size using the wiring area AA1 while ensuring that the overall touch performance of the display panel is not affected.

[0046] like Figure 6As shown, the touch unit 60 further includes a third touch unit 63. The first electrode block 11-1 in the third touch unit 63 and the first electrode block 11-1 in the second touch unit 62 belong to the same first touch electrode 11. The area of the third touch unit 63 is S3, where S2 < S3 ≤ 1.25*S1. Optionally, the area ratio of the first electrode block 11-1 to the second electrode block 12-1 in the second touch unit 62 is equal to the area ratio of the first electrode block 11-1 to the second electrode block 12-1 in the first touch unit 61. In the embodiment of the present invention, both the first touch lead 31 and the second touch lead 32 need to be connected to the touch terminal 20 in the first non-display area NA1, and the wiring area AA1 occupies a certain space in the first direction x. As Figure 6 As shown, when wiring areas AA1 are provided at both lower corner positions of the display area AA, there is still an area in the lower part of the display area AA that is not occupied by the touch leads 30. At this time, the area of the touch unit 60 in this part of the area needs to be designed. S2 < S3 indicates that the width occupied by the wiring area AA1 in the second direction y is smaller than the length of the third touch unit 63 in the second direction y, so the width occupied by the wiring area AA1 in the second direction y is small. And setting S3 ≤ 1.25*S1 ensures that the capacitance difference between the third touch unit 63 and the first touch unit 61 is small, and the capacitance difference between the two can be compensated by subsequent arithmetic processing of the touch sensing signal, so as to design the area of the touch unit 60 around the wiring area AA1, and while using the setting of the wiring area AA1 to reduce the border, ensure that the overall touch performance of the display panel is not affected.

[0047] In some embodiments, in the first direction x, the widths of the first touch unit 61, the second touch unit 62, and the third touch unit 63 are substantially the same. The area differences between the second touch unit 62 and the third touch unit 63 and the first touch unit 61 can be achieved by increasing or decreasing the width of the touch unit in the second direction y. This can ensure that the number of the second touch electrodes 12 extending in the second direction y remains unchanged after the wiring area AA1 is set, and simplifies the design of the touch electrodes. Optionally, the setting of the wiring area AA1 only affects the shape design of one first touch electrode 11, and this first touch electrode 11 participates in the formation of the second touch unit 62 and the third touch unit 63.

[0048] In some embodiments, S3 = S1 and S2 < S1. After setting the wiring area AA1, it occupies a part of the area of the touch unit that was originally required to be set, making the area of the second touch unit 62 smaller. The second touch unit 62 is equivalent to the touch unit with the same area as the first touch unit 61 being compressed in the second direction y. In the second direction y, the sum of the width of the second touch unit 62 and the width of the wiring area AA1 is substantially equal to the width of the third touch unit 63. After adding the wiring area AA1, only the area of the second touch unit 62 needs to be differentially set from the area of the touch unit 60 at other positions. Additionally, setting 0.75*S1 ≤ S2 results in a smaller capacitance difference between the second touch unit 62 and the first touch unit 61, and the capacitance difference between the two can be compensated by subsequent arithmetic processing of the touch sensing signals, enabling the reduction of the border while ensuring that the overall touch performance of the display panel is not affected.

[0049] In some embodiments, Figure 7 Another schematic diagram of a display panel provided by an embodiment of the present invention is shown in Figure 7 As shown, the touch unit 60 includes a first touch unit 61, a second touch unit 62, and a third touch unit 63; where S2 = S1 and S3 ≤ 1.25*S2. After adding the wiring area AA1 in this embodiment, only the area of the third touch unit 63 needs to be differentially set from the area of the touch unit 60 at other positions, and the capacitance difference of the touch can be compensated by arithmetic processing of the touch sensing signals during touch detection, enabling the reduction of the border while ensuring that the overall touch performance of the display panel is not affected.

[0050] In some other embodiments, S1 < S2 ≤ 1.25*S1, S1 < S3 ≤ 1.25*S1, and S2 < S3, that is, the area of the second touch unit 62 is smaller than the area of the third touch unit 63, and the areas of the second touch unit 62 and the third touch unit 63 are both larger than the area of the first touch unit 61. This is not shown in the drawings here.

[0051] In some embodiments, as shown in Figure 6 The width of the third touch unit 63 in the second direction y is L1, and the width of the wiring area AA1 in the second direction y is L2, where L2 ≤ 0.35*L1. Such a setting can ensure that the width of the wiring area AA1 in the second direction y is small, and the width difference between the third touch unit 63 and the touch unit 60 at other positions in the second direction y is small, which is beneficial to reducing the impact of the setting of the wiring area AA1 on the touch performance.

[0052] In some embodiments, Figure 8 is Figure 2An enlarged schematic diagram of the Q position in the central region. Figure 8 The diagram illustrates the shape of the touch electrode 10 and an optional shape of the touch lead 30 within the wiring area AA1. For example... Figure 8 As shown, the touch electrode 10 is grid-shaped and includes multiple hollow areas 10K. The touch electrode 10 is made of metal material, and the hollow areas 10K are connected to the sub-pixels of the display panel. Figure 8 (Not shown in the diagram) The electrodes overlap to prevent the touch electrode 10 from blocking the light emitted by the sub-pixel. The sub-pixel can be an organic light-emitting device or an inorganic light-emitting device. The touch lead 30 in the wiring area AA1 can be made of the same material as the touch electrode 10. Figure 8 As illustrated, the touch leads 30 in the wiring area AA1 adopts a grid-like routing design, which is equivalent to retaining a part of the original touch electrode 10 pattern in the wiring area AA1 as the touch leads 30. This simplifies the manufacturing process, and the touch leads 30 in the wiring area AA1 will not block the light emission of the sub-pixels.

[0053] This invention also provides another display panel, in which the shape of the touch electrodes is slightly different from that in the above embodiments. Figure 9 This is another schematic diagram of a display panel provided in an embodiment of the present invention, such as... Figure 9 As shown, the display panel includes a first touch electrode 11 extending along a first direction x and a second touch electrode 12 extending along a second direction y. The first touch electrode 11 is connected to a touch terminal 20 located in a first non-display area NA1 via a first touch lead 31, and the second touch electrode 12 is connected to the touch terminal 20 via a second touch lead 32. The first touch electrode 11 includes a plurality of first sub-electrodes 111 arranged along the first direction x, and two adjacent first sub-electrodes 111 are connected by at least one bridging portion 113. Figure 9It is shown in the figure that two adjacent first touch electrodes 11 in the second direction y are electrically connected. One of the first touch electrode 11 and the second touch electrode 12 is a touch driving electrode, and the other is a touch sensing electrode. A touch driving signal is provided to the touch driving electrode. There is a touch capacitance between the first touch electrode 11 and the second touch electrode 12. When a finger presses on the display area AA, the touch capacitance at the finger pressing position changes, and the position of the finger pressing is determined according to the sensing signal returned by the touch sensing electrode to achieve touch detection.
