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

[0002] With the rapid development of display technology, touch screen panels have gradually become ubiquitous in people's lives. Currently, touch screen structures can be divided into two categories: mutual capacitance touch structures and self-capacitance touch structures. Self-capacitance touch structures are favored by major panel manufacturers due to their high accuracy and signal-to-noise ratio in touch sensing. Summary of the Invention

[0074] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0075] Unless otherwise defined, the technical or scientific terms used in this disclosure shall have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. The terms “first,” “second,” and similar terms used in this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as “comprising” or “including” mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as “connected” or “linked” are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as “upper,” “lower,” “left,” and “right” are used only to indicate relative positional relationships, and these relative positional relationships may change accordingly when the absolute position of the described objects changes.

[0076] As used herein, “approximately” or “substantially the same” includes the stated value and means within an acceptable range of deviations from the specific value, as determined by a person skilled in the art taking into account the measurement in question and the errors associated with the measurement of the specific quantity (i.e., limitations of the measurement system). For example, “substantially the same” may mean a difference relative to the stated value within one or more standard deviations, or within ±30%, 20%, 10%, or 5%.

[0077] In the accompanying drawings, the thicknesses of layers, films, panels, regions, etc., are enlarged for clarity. Exemplary embodiments are described herein with reference to cross-sectional views that are schematic diagrams of idealized embodiments. Thus, deviations from the shapes shown in the drawings will be expected as a result of, for example, manufacturing techniques and / or tolerances. Therefore, the embodiments described herein should not be construed as limited to the specific shapes of the regions shown herein, but rather include deviations in shape caused, for example, by manufacturing processes. For example, regions illustrated or described as flat may typically have rough and / or non-linear characteristics. Furthermore, sharp corners illustrated may be rounded. Thus, the regions shown in the figures are schematic in nature, and their shapes are not intended to illustrate the precise shapes of the regions, nor are they intended to limit the scope of the claims.

[0078] To keep the following description of the embodiments of this disclosure clear and concise, detailed descriptions of known functions and known components are omitted.

[0079] In existing in-cell touch panel pixel structure designs, each pixel unit (including three sub-pixel units: red, green, and blue) comprises one touch trace and three data traces. Multiple pixel units are periodically arranged along the horizontal and vertical axes according to pixel size, filling the display area. The entire screen is typically designed and divided into blocks according to a set size (e.g., 5mm*5mm) to form the number of touch electrode blocks, such as M rows and N columns of touch electrodes. For example, a 5-inch to 7-inch mobile phone can generally be divided into 32 rows * 18 columns of touch electrode blocks, thus requiring 576 touch traces (32 rows * 18 columns) to correspond to each of the 576 touch electrode blocks. Taking a resolution (e.g., 720 * 1600) as an example, according to the current method of setting touch traces in the area where each pixel unit is located (i.e., each pixel unit area includes one touch trace), there are a total of 720 touch traces. However, since 32 rows * 18 columns of touch electrodes actually require 576 touch traces, 144 touch traces are used as floating touch traces (Dummy TX). Due to the existence of Dummy TX lines, the range of the black matrix is ​​increased, resulting in wasted aperture ratio. The width of the black matrix above the touch traces is wider than the width of the black matrix above the data lines, generally around 11μm wide.

[0080] In addition, in the original pixel design, due to the inconsistency between the touch traces and the Dummy TX signal supply, and when there are fluctuations in the display panel process and differences in the lamp fixture, a probabilistic visible blue line defect may appear on the L0 screen during the initial stage of power-on.

[0081] In view of the above, this disclosure provides a touch display panel, as shown in Figures 1, 2A-2B, and 3. Figure 2A is a schematic diagram of a sub-pixel corresponding to a touch electrode in Figure 1; Figure 2B is an enlarged view of a repeating unit in Figure 2A; and Figure 3 is a schematic diagram of some sub-pixels surrounding a touch trace. The touch display panel includes:

[0082] Substrate 1;

[0083] Multiple subpixels 2;

[0084] Multiple touch electrodes 3;

[0085] Multiple touch traces 4 are arranged along the first direction X and extend along the second direction Y; the touch traces 4 are electrically connected to the touch electrode 3; optionally, the touch traces 4 can be electrically connected to the touch electrode 3 through the first via K1.

[0086] The at least one touch electrode 3 includes at least one first unit 31 and a plurality of second units 32; the first unit 31 and the plurality of second units 32 are arranged along a first direction X; the number of sub-pixels 2 between two adjacent touch lines 4 in the area where the first unit 31 is located is greater than the number of sub-pixels 2 between two adjacent touch lines 4 in the area where the second unit 32 is located. For example, as shown in Figure 2B, the area where the first unit 31 is located has 6 sub-pixels 2 between two adjacent touch lines 4, while the area where the second unit 32 is located has 3 sub-pixels 2 between two adjacent touch lines 4. That is, the area where the touch electrode 3 is located, where the number of sub-pixels 2 between two adjacent touch lines 4 is less, can be designated as the second unit 32, and the area where the number of sub-pixels 2 between two adjacent touch lines 4 is more, can be designated as the first unit 31. The first unit 31 and the second unit 32 are specifically the structure of the touch electrode 3. This division of the touch electrode is done to easily distinguish between areas on the touch display panel where the floating touch lines have been removed and areas where the floating touch lines have not been removed. The first unit 31 and the second unit 32 themselves do not include sub-pixels. The lines and data lines, the sub-pixels, touch traces and data lines in the area where the first unit (or second unit) is located, are only the sub-pixels, touch traces or data lines in the area covered by the orthographic projection of the first unit (or second unit) onto the substrate. That is, the area where the first unit 31 is located can be the area covered by the orthographic projection of the first unit 31 onto the substrate, and the area where the second unit 32 is located can be the area covered by the orthographic projection of the second unit 32 onto the substrate. Optionally, the touch traces 4 of adjacent first units 31 and second units 32 can be shared. That is, the same touch trace 4 can be used as the touch trace 4 in the area where the first unit 31 is located, or as the touch trace 4 in the area where the second unit 32 is adjacent to the first unit 31.

[0087] In this embodiment of the present disclosure, at least one touch electrode 3 includes: at least one first unit 31 and a plurality of second units 32; wherein, the number of sub-pixels 2 between two adjacent touch traces 4 in the area where the first unit 31 is located is greater than the number of sub-pixels 2 between two adjacent touch traces 4 in the area where the second unit 32 is located. That is, without affecting the normal touch function, the floating touch traces (dummy TX) next to some pixels (including three sub-pixels) can be removed, which can reduce the setting of the black matrix that blocks the floating touch traces (dummy TX), thereby improving the aperture ratio of the touch display panel; moreover, the removal of the floating touch traces (dummy TX) can improve the problem of probabilistic visible blue lines appearing on the L0 screen during the initial stage of power-on due to the inconsistent signal supply between the touch traces 4 and the floating touch traces (dummy TX) (the floating touch traces do not load signals when touched).

[0088] In one possible implementation, as shown in Figures 2A and 2B, at least one of the multiple touch electrodes 3 has multiple repeating units 30 in its region; the multiple repeating units 30 are periodically arranged along a first direction X; each repeating unit 30 includes at least one first unit 31 and at least one second unit 32. In this embodiment of the present disclosure, the touch electrode 3 includes multiple repeating units 30, each of which includes at least one first unit 31 and at least one second unit 32. That is, by arranging the touch electrode 3 as multiple repeating units 30, the region where the touch electrode 3 is located, excluding the dummy touch traces (TX), can be arranged in a periodic and regular manner, which is beneficial to the uniformity of the aperture ratio of the touch display panel and reduces the risk of vertical lines and mura defects caused by the removal of the dummy touch traces (TX).

[0089] In one possible implementation, as shown in Figures 2A and 2B, the repeating unit 30 may include a first unit 31 and at least one second unit 32.

[0090] In one possible implementation, the touch display panel includes M rows and N columns of touch electrodes, and at least a portion of the touch electrodes are located in areas with A rows and B columns of pixels, wherein each pixel includes three sub-pixels; the number C of touch traces in the area where the touch electrodes are located satisfies: C < B, where A, B, C, M, and N represent positive integers. In conventional touch display panels, one touch trace is provided next to each column of pixels, that is, one column of pixels corresponds to one touch trace, and the total number of touch traces in the area where the touch electrodes are located is the same as the number of columns of pixels in that area. However, in this embodiment, by removing at least a portion of the floating touch traces (Dummy TX), the final number of touch traces in the area where the touch electrodes are located can be less than the number of columns of pixels in that area, i.e., C < B.

[0091] The touch display panel also has multiple grid lines and multiple data lines; optionally, the direction in which the grid lines extend can be the row direction, and the direction in which the data lines extend can be the column direction.

[0092] For example, the touch display panel may include 32 rows and 18 columns of touch electrodes; the area where the touch electrode 3 is located may include multiple pixels, for example, the area where the touch electrode is located may include 40 columns of pixels and 32 touch traces. That is, compared with conventional touch display panels, when the area where the touch electrode is located contains 40 columns of pixels, 40 touch traces will also be set. However, in this embodiment of the present disclosure, the area where the touch electrode is located can be set with 32 touch traces, which can reduce 8 touch traces (the removed ones can all be floating touch traces (Dummy TX)).

[0093] In one possible implementation, the number C of touch traces in the area where the touch electrodes are located satisfies: C = M. That is, the number of touch traces in the area where the touch electrodes are located can be the same as the number of rows of touch electrodes, with each touch trace corresponding to an electrical connection to one touch electrode. In this embodiment of the present disclosure, the number C of touch traces in the area where the touch electrodes are located satisfies: C = M. That is, all floating touch traces (dummy TX) that do not provide signals to the touch electrodes are removed, and the remaining touch traces are all effective touch traces that provide touch signals to the touch electrodes. This can minimize the setting of black matrices and maximize the aperture ratio of the touch display panel.

[0094] In one possible implementation, the number D of repeating units in the region where the touch electrode 3 is located satisfies the following relationship: D = BM;

[0095] The number of first units E and the number of second units F in the repeating unit satisfy: E = 1; F = (B / D) - 1.

[0096] For example, the touch display panel includes 32 rows and 18 columns of touch electrodes. The area where the touch electrodes are located includes 40 columns of pixels. The number of dummy touch traces (DTX) removed from the area where the touch electrodes are located can be 8 (40-32). The number of repeating units in the area where the touch electrodes are located can also be 8. The number of the first unit in the repeating unit can be 1, and the number of the second unit can be 7 (8-1). That is, one touch trace can be removed in each repeating unit. The number of repeating units in the area where the touch electrodes are located is the same as the number of dummy touch traces (DTX) removed. This makes the area where the dummy touch traces (DTX) are removed in the area where the touch electrodes are located arranged in a periodic pattern, reducing the risk of vertical lines and mura defects caused by the removal of dummy touch traces (DTX).

[0097] In one possible implementation, as shown in Figures 2A and 2B, the number of first units 31 in the repeating unit 30 is less than or equal to the number of second units 32; for example, the repeating unit 30 includes: one first unit 31 and three second units 32; the area where the first unit 31 is located has six sub-pixels 2 between two adjacent touch lines 4; the area where the second unit 32 is located has three sub-pixels 2 between two adjacent touch lines 4.

[0098] In one possible implementation, the first unit is located at the beginning or end of the repeating unit. For example, as shown in Figures 2A and 2B, the first unit 31 is located at the beginning of the repeating unit 30; as another example, as shown in Figures 4A and 4B, the first unit 31 is located at the end of the repeating unit 30.

[0099] In another possible implementation, the second unit is located at the beginning and end of the repeating unit. For example, referring to Figures 5A-5B, 6A, and 6B, the second unit 32 is located at the beginning and end of the repeating unit 30. That is, the first unit 31 is located inside the repeating unit 30, and the second unit 32 is located at the beginning and end of the repeating unit 30.

[0100] In another possible implementation, as shown in Figures 7A-7D, the repeating unit 30 includes: a first unit 31 and a second unit 32; the area where the first unit 31 is located has six sub-pixels 2 between two adjacent touch lines 4; the area where the second unit 32 is located has three sub-pixels 2 between two adjacent touch lines 4. In this embodiment of the disclosure, the repeating unit 30 includes: a first unit 31 and a second unit 32; that is, the number of second units 32 in the repeating unit 30 can be adjusted according to the specific resolution of the touch display panel. For example, the number of first units 31 and second units 32 in the repeating units 30 corresponding to Figures 2A-2B, 3, 4A-4B, 5A-5B, and 6A-6B can correspond to an upgraded high-definition display panel, for example, it can have a resolution of 1600*900; the number of first units 31 and second units 32 in the repeating units 30 corresponding to Figures 7A-7D can correspond to a full high-definition display panel, for example, it can have a resolution of 1920*1080.

[0101] Referring to Figures 7A-7D, the touch electrode 3 further includes: a third touch unit 33 and a fourth touch unit 34; the number of sub-pixels 2 between two adjacent touch lines 4 in the area where the third touch unit 33 is located is greater than the number of sub-pixels 2 between two adjacent touch lines 4 in the area where the second unit 32 is located; the number of sub-pixels 2 between two adjacent touch lines 4 in the area where the fourth touch unit 34 is located is greater than the number of sub-pixels 2 between two adjacent touch lines 4 in the area where the second unit 32 is located; the third touch unit 33 is located at the starting end of the touch electrode 3 in the first direction X, and the fourth touch unit 34 is located at the ending end of the touch electrode 3 in the first direction X.

[0102] In this embodiment of the present disclosure, the touch electrode 3 further includes: a third touch unit 33 and a fourth touch unit 34; the third touch unit 33 is located at the starting end of the touch electrode 3 in the first direction X, and the fourth touch unit 34 is located at the ending end of the touch electrode 3 in the first direction X. That is, according to the specific resolution of the touch display panel, the touch electrode 3 can be provided with other touch units (such as the third touch unit 33 and the fourth touch unit 34) other than the repeating unit 30, after removing the touch lines, so that the number of floating touch lines removed by the touch electrode matches the resolution.

[0103] In one possible implementation, the third touch unit 33 may have the same distribution as the first unit 31, that is, there are 6 sub-pixels 2 between adjacent touch lines 4; in another possible implementation, the fourth touch unit 34 may also have the same distribution as the first unit 31.

[0104] In another possible implementation, as shown in Figure 8, the first unit 31 and the second unit 32 are randomly arranged within the touch electrode 3.

[0105] In another possible implementation, as shown in Figure 9, the first unit 31 is located only at the beginning or end of the touch electrode 3 in the first direction X. That is, in this embodiment of the present disclosure, the area where the floating touch traces have been removed can be concentrated at the edge area of ​​the touch electrode 3. This arrangement allows for connection with existing conventional terminals without requiring the remaining touch traces to be re-corresponded to conventional terminals on the bonding side after the floating touch traces have been removed, and without requiring wire routing through vias for connection.

[0106] In practical design, after removing the dummy TX in a repeating unit, it is necessary to consider minimizing the difference in aperture ratio for the same color, or to avoid situations where a sub-pixel of one color corresponds to more than two aperture ratios, otherwise the brightness difference at low gray levels will lead to the risk of vertical stripes.

[0107] If the increased aperture width after deleting Dummy TX can be evenly divided (i.e., divisible), then the R, G, and B sub-pixels in a repeating unit have only one aperture ratio, and the aperture width of each sub-pixel can be equal.

[0108] If the increased aperture width after deleting the dummy TX cannot be evenly divided (i.e., not divisible), then two aperture ratios will be needed. Based on the differences in human eye color sensitivity, the blue subpixel should be preferred, while keeping the aperture ratios of the red and green subpixels consistent. That is, the blue subpixel has one aperture width, and the red and green subpixels have another. When two aperture ratios exist, there are four possible allocation schemes for different subpixels. Specifically, when two aperture ratios exist, the size of the aperture ratio can be calculated using a formula, according to the way the touch electrodes of the relevant mobile phone product are divided. For example, if 32 rows * 18 columns = 576 touch blocks are needed, each touch electrode will have 40 columns of pixels, 32 touch traces, and 8 dummy TXs. When these 8 dummy TXs are deleted... After TX, the space of 8*11μm=88μm is divided into 40*3=120 sub-pixels, as shown in Formula 1 and Formula 2. It is necessary to consider dividing the increased opening width into two types: e and f. Then the number of sub-pixels with space e is m, and the number of sub-pixels with space f is 120-m. According to Formula 3, if f is 0.73μm (taking a touch display panel with 32 rows * 18 columns = 576 touch electrode blocks, a total of 32*18=576 touch traces are needed to correspond to the 576 touch electrode blocks. Taking a 6.52-inch 20:9 HD+ resolution (720*1600) as an example, according to the conventional touch trace and pixel setting relationship, there are a total of 720 touch traces. Thus, 144 touch traces are used as Dummy TX. When 144 Dummy TX traces are deleted... After TX, the space of 144*11μm=1584μm is evenly distributed into 720*3=2160 sub-pixels. Each sub-pixel can increase the space by about 0.73μm in the pixel row direction, and the aperture ratio is improved by about 0.73 / 22.6≈3%. Considering the minimum difference in aperture ratio, the value of ef in Formula 3 needs to be minimized. At this time, m is 40 and e is 0.74μm, that is, there are 40 sub-pixels with space e and 80 sub-pixels with space f. At this time, space f can be distributed into the sub-pixels of the two colors and space e can be distributed into the sub-pixels of the third color, ensuring that one color corresponds to one aperture ratio, effectively reducing the risk of vertical stripes.

[0109] The following provides a detailed explanation of the aperture widths of different sub-pixels:

[0110] For example, in one possible implementation, referring to Figure 10A, the touch display panel has multiple openings 20, each opening 20 having the same width along the first direction X. That is, after deleting the dummy TX, the increased opening width can be evenly distributed, so the R, G, and B sub-pixels in a repeating unit have only one aperture ratio, and the opening width of each sub-pixel can be equal; optionally, the opening 20 can be a light-transmitting area of ​​the touch display panel corresponding to the sub-pixel, specifically, it can be an opening of the black matrix layer at the sub-pixel;

[0111] For example, in another possible implementation, referring to Figures 10B-10E, the plurality of openings 20 includes: a plurality of first openings 201 and a plurality of second openings 202; the width a1' of each first opening 201 in the first direction X is the same, and the width a2' of each second opening 202 in the first direction X is the same; the width a1' of the first opening 201 in the first direction X is different from the width a2' of the second opening 202 in the first direction X. That is, when the increased opening width cannot be evenly divided after deleting the Dummy TX, in order to avoid having three or more opening ratios, which would lead to a less uniform opening ratio of the touch display panel and affect the viewing effect, two opening ratios can be set to make the opening ratio of each sub-pixel of the display panel as uniform as possible when the increased opening width cannot be evenly divided.

[0112] In one possible implementation, the first opening 201 and the second opening 202 satisfy the following relationships: a1'-a=e; (Formula 1) a2'-a=f; (Formula 2)

[0113] e*m+f*(3B-m) =(BM)*b; that is, ef=[(BM)b-3Bf] / m (Formula 3)

[0114] Where a1' represents the width of the first opening, a2' represents the width of the second opening, a represents the opening width when a touch trace is set for every two adjacent pixels, that is, the opening width of the display panel before the floating touch trace is deleted, e represents the increased width of the first opening, f represents the increased width of the second opening, m represents the number of first openings in the area where the repeating unit is located, and b represents the width of the touch trace in the first direction.

[0115] For example, taking a touch display panel with 32 rows * 18 columns = 576 touch electrode blocks, and a size of 6.52 inches with a resolution of (720*1600), the width of the touch trace in the first direction is 11μm. Each touch electrode has 40 columns of pixels, 32 touch traces, and 8 dummy TXs. When these 8 dummy TXs are deleted, according to Formula 3, the following condition is met: e*m + f*(3*40-m) = (40-32)*11. That is, the space of 8*11μm = 88μm is divided into 40*3 = 120 sub-pixels. If f is 0.73μm, and the minimum value of ef is required, we can get m as 40 and e as 0.74μm.

[0116] In one possible implementation, referring to Figures 10B-10C, the width a1' of the first opening 201 in the first direction X is greater than the width a2' of the second opening 202 in the first direction X; the touch display panel includes: a red opening R, a green opening G, and a blue opening B; at least a portion of the blue opening B serves as the first opening 201; the red opening R and the green sub-pixel G opening serve as the second opening 202. In this embodiment, since the human eye is less sensitive to blue color, using at least a portion of the blue pixel opening B as the first opening 201 with a larger opening width can reduce the visual differences caused to the human eye due to different opening ratios of different colors.

[0117] For example, as shown in Figure 10B, only the blue opening B within the first unit 31 can be used as the first opening 201; the red opening R and the green sub-pixel G opening can be used as the second opening 202. Alternatively, as shown in Figure 10C, all the blue openings B within the first unit 31 can be used as the first opening 201; the red opening R and the green sub-pixel G opening can be used as the second opening 202.

[0118] In one possible implementation, referring to FIG10D, the width a1' of the first opening 201 in the first direction X is greater than the width a2' of the second opening 202 in the first direction X; the touch display panel includes: a red opening R, a green opening G, and a blue opening B; the green opening G serves as the first opening 201; the red opening R and the blue opening B serve as the second opening 202.

[0119] In one possible implementation, referring to FIG10E, the width a1' of the first opening 201 in the first direction X is greater than the width a2' of the second opening 202 in the first direction X; the touch display panel includes: a red opening R, a green opening G, and a blue opening B; the red opening R serves as the first opening 201; the green opening G and the blue opening B serve as the second opening 202.

[0120] It should be noted that Figures 10A-10E only show the aperture ratio at six sub-pixels. The aperture settings at other locations can be the same as those at the six sub-pixels.

[0121] In one possible implementation, as shown in FIG10A, the touch display panel includes: a black matrix layer; the black matrix layer includes: a plurality of openings 2.

[0122] In one possible implementation, as shown in FIG10A, the touch display panel may include an array substrate 100 and a counter substrate 200 disposed opposite to each other, wherein a black matrix layer may be disposed on the counter substrate 200. Touch traces 4 and touch electrodes 3 may be disposed on the array substrate 100.

[0123] In one possible implementation, as shown in FIG3, the array substrate may further include multiple data lines 5 extending along the second direction Y and multiple gate lines 6 extending along the first direction X; the touch traces 4 may be in the same layer and material as the data lines 5.

[0124] In one possible implementation, referring to Figures 11, 12A-12C, where Figure 11 is a schematic diagram of the distribution of touch traces corresponding to a touch electrode, Figure 12A is an enlarged schematic diagram of the dashed frame S1 in Figure 11, Figure 12B is an enlarged schematic diagram of the dashed frame S2 in Figure 11, and Figure 12C is an enlarged schematic diagram of the dashed frame S3 in Figure 11, the touch display panel includes: multiple bonding terminals, multiple leads 8, and multiple adapter lines 7; at least some of the touch traces 4 are electrically connected to one end of the leads 8 through the adapter lines 7, and the other end of the leads 8 is electrically connected to the bonding terminals; the adapter lines 7 and the touch traces 4 are located on different layers, and the adapter lines 7 and the leads 8 are located on different layers. In this embodiment of the disclosure, the touch display panel includes: multiple adapter lines 7; at least some of the touch traces 4 are electrically connected to one end of the lead 8 through the adapter lines 7. The adapter lines 7 and the touch traces 4 are located on different layers, and the adapter lines 7 and the lead 8 are located on different layers. This ensures that after removing the floating touch traces, the remaining touch traces are electrically connected to the existing bonding terminals, thus avoiding the problem of incorrect touch information when the signals of the two areas are not connected in a one-to-one correspondence.

[0125] Assuming the current IC pin definition remains unchanged, the terminals of the touch signals inside the IC pin side are concentrated, and the touch traces in the display area are arranged in a regular manner. To ensure that the signals in the two areas are connected in a one-to-one correspondence, as shown in Figure 11, the bonding side adapter cable can be connected by winding the wire in a way that periodically gathers from the edge to the center.

[0126] In one possible implementation, as shown in Figures 12A-12C, the touch display panel further includes: a plurality of first adapter hole groups Z1 and a plurality of second adapter hole groups Z2; the first adapter hole group Z1 includes: a plurality of first vias K1; the second adapter hole group Z2 includes a plurality of second vias K2; one end of the adapter cable 7 is electrically connected to the touch trace 4 through the first adapter hole group Z1, and the other end of the adapter cable 7 is electrically connected to one end of the lead wire 8 through the second adapter hole group Z2.

[0127] In one possible implementation, referring to FIG12D, the touch display panel includes: a first row of adapter holes Z100 and a second row of adapter holes Z200; the first row of adapter holes Z100 includes: a plurality of first adapter hole groups Z1 arranged sequentially along a first direction X; the second row of adapter holes Z200 includes: a plurality of second adapter hole groups Z2 arranged sequentially along the first direction X; the touch display panel has a first axis k1 extending along a second direction Y and passing through the center O2 of the second row of adapter holes Z200; the first adapter hole groups Z1 and the second adapter hole groups Z2 are at least partially connected to the same adapter cable 7, wherein the second adapter hole groups Z2 are located on the side of the first adapter hole groups Z1 closer to the first axis k1. For example, in FIG12D, the leftmost first adapter hole group Z1 in the first row of adapter holes Z100 and the leftmost second adapter hole Z2 in the second row of adapter holes Z200 are connected to the same adapter cable 7, wherein the second adapter hole group Z2 is closer to the first axis k1.

[0128] In this embodiment of the present disclosure, a first adapter hole group Z1 and a second adapter hole group Z2 are connected to the same adapter cable 7. The second adapter hole group Z2 is located on the side of the first adapter hole group Z1 that is closer to the first axis k1. That is, the second adapter hole group Z2 is closer to the first axis k1 than the first adapter hole group Z1, so as to achieve electrical connection with the original bonding terminal.

[0129] It should be noted that, in order to more clearly illustrate the relationship between the multiple first adapter hole groups Z1 and the multiple second adapter hole groups Z2, Figure 12D only shows schematic diagrams of the first adapter hole groups Z1, the second adapter hole groups Z2, and some adapter wires 7 in Figures 12A-12C. Other adapter wires and wiring can be as shown in Figures 12A-12C, and the embodiments disclosed herein are not limited thereto.

[0130] In one possible implementation, as shown in FIG12A, at least a portion of the touch trace includes: a first touch trace portion 41 and a second touch trace portion 42; the second touch trace portion 42 connects to the side of the first touch trace portion 41 facing the bonding terminal, and bends from the first touch trace portion 41 toward the adjacent touch trace 4. For example, as shown in FIG12A, the second touch trace portion 42 bends toward the touch trace 4 on the left. In this way, the space after removing the touch trace is effectively utilized for the layout of the first via group Z1 and the adapter cable 7.

[0131] In one possible implementation, as shown in Figures 12A-12C, the touch display panel includes: a plurality of adapter cable groups 70; each adapter cable group 70 includes a plurality of adapter cables 7; touch traces 4 in the same area of ​​the touch electrode 3 are electrically connected to the other end of the lead 8 through the adapter cables 7 of the same adapter cable group 70; touch traces 4 in different areas of the touch electrode 3 are electrically connected to the other end of the lead 8 through the adapter cables 7 of different adapter cable groups 70; in the same adapter cable group 70, the length of at least one adapter cable 7 near the end of the adapter cable group 70 is greater than the length of the adapter cable 7 located in the middle of the adapter cable group 70.

[0132] In one possible implementation, referring to Figures 13A-13B, the touch display panel includes at least one corner region R; at least some of the data lines 5 at the corner region R have different extension lengths; the touch display panel includes at least one corner region R; the touch display panel has a display area and a peripheral area located around the display area; the corner region R has multiple pixel groups P extending along a second direction Y and arranged along a first direction X, and in the direction from the display area to the peripheral area, the length of at least some of the pixel groups P along the second direction Y decreases sequentially; of the data lines 5 and the touch traces 4, only the data lines 5 are provided between adjacent pixel groups P at the outermost edge of the corner region. Referring to Figure 2B, due to the removal of the touch traces, there are no touch traces between the two outermost pixel groups, so the data lines 5 are used to replace the touch traces to improve the display difference caused by the lack of pixels in the corner region.

[0133] Referring to Figures 13A and 13B, for the corner region R, there are multiple pixel groups P extending along the second direction Y. In the direction from the display area to the peripheral area, at least some pixel groups P have a progressively decreasing extension direction in the second direction Y. That is, as shown in Figure 13B, the extension length of the outermost first pixel group P1 in the second direction Y is less than the extension length of the second pixel group P2 closer to the display area. This achieves a gradient reduction in the number of pixels in the corner region R, and no touch trace 4 is provided between adjacent pixel groups P. Furthermore, in the corner region R, the data line 5 is routed to the side closer to the peripheral area. The sub-pixels provide data signals. For example, in Figure 13B, the second data line 52, the third data line 53, and the fourth data line 54 provide data signals to the sub-pixels to their right, while the first trace 51 does not provide data signals to the pixels in the current first pixel column group P1. The first trace 51 can be a touch trace, which "seales" the edge pixels of the current first pixel column group P1. The first trace 51, the second data line 52, and the third data line 53 terminate at the current first pixel column group P1, and the fourth data line 54 continues to extend upward and terminates at the next second pixel column group P2. The termination position of the fourth data line 54 is the same as that of its adjacent data line on the left.

[0134] In one possible implementation, as shown in Figures 13A-13B, the width of the data line 5 at the outermost edge in the first direction X can be greater than the width of the data line 5 at other positions in the first direction X.

[0135] Based on the same inventive concept, embodiments of this disclosure also provide a touch display device, which includes a touch display panel as provided in embodiments of this disclosure.

[0136] In this embodiment of the present disclosure, at least one touch electrode 3 includes: at least one first unit 31 and a plurality of second units 32; wherein, the number of sub-pixels 2 between two adjacent touch traces 4 in the area where the first unit 31 is located is greater than the number of sub-pixels 2 between two adjacent touch traces 4 in the area where the second unit 32 is located. That is, without affecting the normal touch function, the floating touch traces (dummy TX) next to some pixels (including three sub-pixels) can be removed, which can reduce the setting of the black matrix that blocks the floating touch traces (dummy TX), thereby improving the aperture ratio of the touch display panel; moreover, the removal of the floating touch traces (dummy TX) can improve the problem of probabilistic visible blue lines appearing on the L0 screen during the initial stage of power-on due to the inconsistent signal supply between the touch traces 4 and the floating touch traces (dummy TX) (the floating touch traces do not load signals when touched).

[0137] This disclosure proposes a pixel structure to improve the transmittance of an embedded capacitive touchscreen. To meet the increasing demands for higher customer specifications and lower costs, without increasing the number of photomasks, existing mass production processes are utilized. By reducing unnecessary dummy TX traces and mitigating the risk of vertical lines, the saved space is evenly distributed among pixels, increasing the aperture ratio and ultimately achieving a transmittance improvement of over 3%. Simultaneously, it also improves the probabilistic visible blue line defects under L0 screen conditions.

[0138] In some embodiments, the display panel provided in this disclosure may further include a liquid crystal layer between an array substrate and a counter substrate, a first polarizer on the side of the array substrate away from the counter substrate, and a second polarizer on the side of the counter substrate away from the array substrate, wherein the polarization direction of the first polarizer and the polarization direction of the second polarizer are perpendicular to each other. Other essential components of the display panel are those which should be understood by those skilled in the art and will not be described in detail here, nor should they be construed as limiting the scope of this disclosure.

[0139] Based on the same inventive concept, this disclosure also provides a display device, comprising the display panel described above and a backlight module located on the light-incident side of the display panel. The backlight module can be a direct-lit backlight module or an edge-lit backlight module. Optionally, the edge-lit backlight module may include LED strips, stacked reflective sheets, light guide plates, diffusers, prism groups, etc., with the LED strips located on one side of the thickness direction of the light guide plate. The direct-lit backlight module may include a matrix light source, a reflective sheet, a diffuser plate, and a brightness enhancement film stacked on the light-emitting side of the matrix light source, with the reflective sheet including openings directly opposite the positions of the LEDs in the matrix light source. The LEDs in the LED strips and the LEDs in the matrix light source can be light-emitting diodes (LEDs), such as miniature LEDs (Mini LEDs, Micro LEDs, etc.).

[0140] Micro-LEDs, at the sub-millimeter or even micrometer scale, are self-emissive devices, just like organic light-emitting diodes (OLEDs). Like OLEDs, they offer a range of advantages, including high brightness, ultra-low latency, and ultra-wide viewing angles. Furthermore, because inorganic LEDs emit light based on more stable and lower-resistance metal semiconductors, they offer advantages over organic LEDs, such as lower power consumption, better resistance to high and low temperatures, and longer lifespan. When used as backlights, micro-LEDs can achieve more precise dynamic backlighting effects, effectively improving screen brightness and contrast while eliminating glare caused by traditional dynamic backlighting between bright and dark areas, thus optimizing the visual experience.

Optionally, the control chip is a central processing unit, digital signal processor, system-on-a-chip (SoC), etc. For example, the control chip may also include a memory, a power module, etc., and achieve power supply and signal input / output functions through additionally provided wires, signal lines, etc. For example, the control chip may also include hardware circuits and computer-executable code. The hardware circuit may include conventional very-large-scale integrated circuits (VLSI) or gate arrays, as well as existing semiconductors or other discrete components such as logic chips and transistors; the hardware circuit may also include field-programmable gate arrays, programmable array logic, programmable logic devices, etc. Furthermore, those skilled in the art will understand that the above structure does not constitute a limitation on the display device provided in the embodiments of this disclosure. In other words, the display device provided in the embodiments of this disclosure may include more or fewer of the above components, or combine certain components, or have different component arrangements.
