[0085] 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 protection scope of this disclosure.

[0086] It should be noted that, for clarity and / or descriptive purposes, the dimensions and relative dimensions of components may be enlarged in the accompanying drawings. Therefore, the dimensions and relative dimensions of the individual components are not necessarily limited to those shown in the drawings. In the specification and accompanying drawings, the same or similar reference numerals indicate the same or similar parts.

[0087] When an element is described as being "on" another element, "connected to" another element, or "attached to" another element, the element may be directly on, directly connected to, or directly attached to the other element, or there may be intermediate elements. However, when an element is described as being "directly on" another element, "directly connected to" another element, or "directly attached to" another element, there are no intermediate elements. Other terms and / or expressions used to describe relationships between elements should be interpreted in a similar manner, such as "between" versus "directly between," "adjacent" versus "directly adjacent," or "on" versus "directly on," etc. Furthermore, the term "connection" can refer to a physical connection, an electrical connection, a communication connection, and / or a fluid connection. Moreover, the X-axis, Y-axis, and Z-axis are not limited to the three axes of a Cartesian coordinate system and can be interpreted in a broader sense. For example, the X-axis, Y-axis, and Z-axis may be perpendicular to each other, or may represent different directions that are not perpendicular to each other. For the purposes of this disclosure, “at least one of X, Y, and Z” and “at least one selected from the group consisting of X, Y, and Z” can be interpreted as only X, only Y, only Z, or any combination of two or more of X, Y, and Z such as XYZ, XYY, YZ, and ZZ. As used herein, the term “and / or” includes any and all combinations of one or more of the listed related items.

[0088] It should be noted that although the terms "first," "second," etc., may be used herein to describe various components, members, elements, regions, layers, and / or parts, these components, members, elements, regions, layers, and / or parts should not be limited by these terms. Rather, these terms are used to distinguish one component, member, element, region, layer, and / or part from another. Thus, for example, the first component, first member, first element, first region, first layer, and / or first part discussed below may be referred to as a second component, second member, second element, second region, second layer, and / or second part without departing from the teachings of this disclosure.

[0089] For ease of description, spatial relation terms, such as “above,” “below,” “left,” “right,” etc., may be used herein to describe the relationship between one element or feature and another element or feature as shown in the figure. It should be understood that spatial relation terms are intended to cover other orientations of the device in use or operation besides those described in the figure. For example, if the device in the figure were inverted, an element described as “below” or “under” other elements or features would be oriented “above” or “on top” other elements or features.

[0090] Those skilled in the art will understand that, unless otherwise stated herein, the term "thickness" refers to the dimension along the surface perpendicular to the display substrate on which the various film layers are disposed, i.e., the dimension along the light emission direction of the display substrate.

[0091] In this article, unless otherwise stated, the term "patterning process" generally includes steps such as photoresist coating, exposure, development, etching, and photoresist stripping. The term "one-step patterning process" refers to the process of forming patterned layers, components, and parts using a single photomask.

[0092] It should be noted that the terms "same layer," "same layer setup," or similar expressions refer to a layer structure formed by using the same film deposition process to create a film layer for forming a specific pattern, and then using the same photomask to pattern this film layer in a single patterning process. Depending on the specific pattern, a single patterning process may include multiple exposure, development, or etching processes, and the specific pattern in the resulting layer structure may be continuous or discontinuous. These specific patterns may also be at different heights or have different thicknesses.

[0093] In this document, unless otherwise stated, the term "electrical connection" can mean that two components or elements are directly electrically connected, for example, component or element A is in direct contact with component or element B, and an electrical signal can be transmitted between them; it can also mean that two components or elements are electrically connected through a conductive medium, such as a conductive wire, for example, component or element A is electrically connected to component or element B through a conductive wire to transmit an electrical signal between the two components or elements; it can also mean that two components or elements are electrically connected through at least one electronic component, for example, component or element A is electrically connected to component or element B through at least one thin-film transistor to transmit an electrical signal between the two components or elements.

[0094] Figure 1 A schematic diagram illustrating a display substrate is shown in one example, such as... Figure 1 As shown, in this example, the display substrate is a liquid crystal display substrate, and the display substrate uses in-cell technology to integrate display and touch. The display substrate includes a substrate and multiple pixel units P disposed on the substrate. Each pixel unit P includes multiple sub-pixels 11, which can display multiple colors. Different sub-pixels 11 display different colors. For example, each pixel unit P includes red sub-pixels, green sub-pixels, and blue sub-pixels. The display substrate adopts a 2-pixel-2-domain (2P2D) sub-pixel structure design. Each sub-pixel 11 includes multiple strip-shaped pixel electrodes 12, and the multiple strip-shaped pixel electrodes 12 of each sub-pixel 11 are separated by slits 13. The term "2-pixel-2-domain" means that the pixel electrodes 12 of two adjacent rows of sub-pixels 11 extend in different directions, and the pixel electrodes 12 of each two adjacent rows of sub-pixels 11 are approximately symmetrical with respect to the gate lines 14. Therefore, in the display substrate, for two adjacent rows of sub-pixels 11, the pixel electrode 12 and the common electrode of one row of sub-pixels 11 can form a first domain electric field, and the pixel electrode 12 and the common electrode of the other row of sub-pixels 11 can form a second domain electric field. The directions of the first and second domain electric fields are different; in other words, the directions of the electric fields corresponding to each pair of adjacent rows of sub-pixels 11 form a certain angle. Consequently, the light emission directions of each pair of adjacent rows of sub-pixels 11 can compensate for each other, which is beneficial for improving the display effect.

[0095] In this example, the display substrate also includes touch electrodes, which are multiplexed as common electrodes for each subpixel. Each touch electrode includes multiple touch units 15, each touch unit 15 covering multiple subpixels 11. Each touch unit 15 is connected to the touch recognition module through at least one touch line, and different touch units 15 are connected to the touch recognition module through different touch lines.

[0096] In this example, the display substrate can have a resolution of 720*1560 (column * row). The touch unit 15 in the display substrate can have an 18H*32V structure, meaning that in the third direction (i.e., the row direction), the touch unit 15 covers 18 columns of sub-pixels 11, and in the fourth direction (i.e., the column direction), the touch unit 15 covers 32 rows of sub-pixels 11. However, since the resolution of the display substrate is 720*1560, and 1560 is not divisible by 32, to solve this problem, in this example, the touch unit 15 can be configured as follows:

[0097] For two adjacent rows of touch units 15, one row of touch units 15 covers 48 rows of subpixels 11, and the other row of touch units 15 covers 49 rows of subpixels 11.

[0098] Figure 2a and Figure 2b The illustration shows a schematic diagram of two adjacent rows of touch units in an example, wherein, Figure 2a The previous row shows the touch unit 15. Figure 2b The touch unit 15 in the next row is shown, and, Figure 2a The touch unit in the middle covers 48 rows of sub-pixels 11. Figure 2b The touch unit covers 49 rows of sub-pixels 11. Combined with... Figure 2a and Figure 2b As shown, the touch unit 15 includes a plurality of touch blocks 151, at least one touch block 151 is correspondingly disposed with at least one sub-pixel 11, and different touch blocks 151 are correspondingly disposed with different sub-pixels 11. For example, touch blocks 151 and sub-pixels 11 are configured in a one-to-one correspondence. Since the display substrate adopts a two-image, two-domain design, in order to match the touch blocks 151 with the sub-pixels 11, the touch blocks 151 are generally disposed in an inclined manner, and the inclined direction of the touch blocks 151 is the same as the inclined direction of the pixel electrode 12 of the sub-pixel 11 corresponding to the touch block 151.

[0099] The inventors discovered during their research that, in the fourth direction, the multiple touch blocks 151 covering the 48 rows of sub-pixels 11 of the touch unit 15 form a periodically repeating pattern, while the multiple touch blocks 151 covering the 49 rows of sub-pixels 11 do not. This results in a significant difference in patterns between the touch units 15 covering the 48 rows of sub-pixels 11 and those covering the 49 rows of sub-pixels 11. Specifically, as... Figure 2a As shown, in the touch unit 15 covering 48 rows of subpixels, the first row of touch blocks 151 is tilted to the right, and the last row of touch blocks 151 is tilted to the left; as Figure 2bAs shown, the first row of touch blocks 151 in the touch unit 15 covering 49 rows of subpixels is tilted to the right, and the last row of touch blocks 151 is also tilted to the right. This results in a significant difference in the pattern between adjacent rows of touch units 15. Consequently, the reflected light effects of adjacent rows of touch units 15 are different, and thus, visible horizontal lines will be formed between adjacent rows of touch units 15, which is to say, horizontal line defects are produced.

[0100] In view of this, embodiments of the present disclosure provide a display substrate, Figure 3a This schematic diagram illustrates one of the display substrates in an embodiment of the present disclosure. Figure 3b This schematically illustrates a second diagram of a display substrate according to an embodiment of the present disclosure. Figure 3c This schematic diagram illustrates the third aspect of the display substrate in an embodiment of this disclosure, in conjunction with... Figures 3a to 3c As shown in this embodiment, the display substrate can be divided into a display area AA and a non-display area NA located outside the display area AA. The display substrate includes: a substrate 21, a touch electrode 22, multiple pixel units P, and multiple touch lines 24. Each pixel unit P includes multiple sub-pixels 23, which are disposed in the display area AA. The multiple sub-pixels 23 can be arranged in an array along a third direction (i.e., the row direction) and a fourth direction (i.e., the column direction). The multiple sub-pixels 23 can display multiple colors, and different sub-pixels 23 can display different colors. For example, each pixel unit P includes a red sub-pixel, a green sub-pixel, and a blue sub-pixel. Figure 4 Schematic illustration Figure 3b One of the schematic diagrams at position A in the middle, for clarity. Figure 4 Only subpixel 23 and the gate line are shown, as shown in the image. Figure 4 As shown, at least a portion of the sub-pixels 23 include a first electrode 231. For two adjacent rows of sub-pixels 23, the first electrode 231 of one row of sub-pixels 23 extends toward a first direction, and the first electrode 231 of the other row of sub-pixels 23 extends toward a second direction. The first direction and the second direction intersect.

[0101] For example, each sub-pixel 23 includes a first electrode 231. Optionally, a second electrode that can cooperate with the first electrode 231 of each sub-pixel 23 is also provided on the display substrate. For example, the second electrode can be provided on the side of the first electrode 231 away from the substrate 21.

[0102] Optionally, the display substrate can be a liquid crystal display substrate, and each sub-pixel 23 further includes a liquid crystal layer (not shown in the figure). The first electrode 231 and the second electrode can generate a corresponding liquid crystal electric field under the drive of the driving signal. The liquid crystal in the liquid crystal layer can be deflected under the action of the liquid crystal electric field, thereby realizing the corresponding display function. Exemplarily, the liquid crystal layer can be disposed between the first electrode 231 and the second electrode. One of the first electrode 231 and the second electrode can be a pixel electrode, and the other can be a common electrode. For example, the first electrode 231 is a pixel electrode, and the second electrode is a common electrode.

[0103] Optionally, the multiple subpixels 23 are divided into multiple groups, at least one group includes two adjacent rows of subpixels 23, and the subpixels 23 in different groups belong to different rows. In other words, in this embodiment of the present disclosure, the multiple rows of subpixels 23 are repeatedly arranged in the display substrate in two rows as a period. Furthermore, for any group of subpixels 23, the first electrode 231 of one row of subpixels 23 extends toward a first direction, and the first electrode 231 of the other row of subpixels 23 extends toward a second direction. That is to say, in this embodiment of the present disclosure, the display substrate adopts the two-image, two-domain subpixel structure design mentioned above.

[0104] In this embodiment, the touch electrode 22 can be reused as a second electrode for a sub-pixel, as will be described in detail below, and will not be repeated here. Figure 3a As shown, the touch electrode 22 includes multiple touch units 221. At least one touch unit 221 is connected to at least one touch line 24. Different touch units 221 are connected to different touch lines 24. For example, each touch unit 221 is connected to one touch line 24, or each touch unit 221 is connected to multiple touch lines 24. The specific connection can be determined according to actual needs and is not limited here. Each touch unit 221 can be connected to the touch recognition module through the touch line 24. For example, each touch unit 221 is connected to a pin of the touch recognition module through the touch line 24.

[0105] In this embodiment, the non-display area NA of the display substrate includes a signal input side (the lower side of the display area AA in FIG. 3). A driver chip IC can be disposed on the signal input side, and the touch recognition module can be integrated into the driver chip IC. For example, the driver chip IC can be a TDDI chip. Multiple touch lines 24 can extend along a fourth direction to the lower side of the display area AA, thereby connecting to the touch recognition module. During the display phase, the TDDI chip can provide drive signals for display to the touch unit 221 through the touch lines 24. At this time, the touch unit 221 is multiplexed as a second electrode, and a corresponding electric field can be formed between the first electrode 231 and the second electrode to realize the display function. During the touch phase, the TDDI chip can provide touch signals for touch recognition to realize the touch function.

[0106] like Figure 3c As shown, the touch unit 221 may include multiple touch blocks 2211, combined with Figure 3b , Figure 3c and Figure 4 As shown, at least one touch block 2211 of the touch unit 221 is correspondingly disposed with at least one sub-pixel 23, and different touch blocks 2211 are correspondingly disposed with different sub-pixels 23. For example, touch blocks 2211 and sub-pixels 23 are configured in a one-to-one correspondence. Optionally, the touch block 2211 is strip-shaped, and the touch block 2211 can be tilted. The extending direction of the touch block 2211 is approximately the same as the extending direction of the first electrode 231 of its corresponding sub-pixel 23.

[0107] In this embodiment, each touch unit 221 covers an even number of rows of subpixels 23. Therefore, for each row of subpixels 23 covered by each touch unit 221, if the first electrode 231 of the first row of subpixels 23 extends in a first direction, the first electrode 231 of the last row of subpixels 23 extends in a second direction. Thus, for any touch unit 221, if the touch blocks 2211 in the first row of that touch unit 221 extend in the first direction, the touch blocks 2211 in the last row extend in the second direction. In other words, in the fourth direction, the multiple touch blocks 2211 of each touch unit 221 are periodically repeating patterns. Therefore, the overall pattern of two adjacent rows of touch units 221 will not have a significant deviation, thereby avoiding the horizontal stripe problem caused by the large difference in the patterns of two adjacent rows of touch units 221, and thus improving the display effect.

[0108] It should be noted that the embodiments disclosed herein use a liquid crystal display substrate as an example to illustrate the display substrate of the embodiments disclosed herein. It is understood that the display substrate of the embodiments disclosed herein may also be other types of display substrates, such as OLED display substrates, etc. The specific type can be determined according to actual needs and is not limited here.

[0109] It should also be noted that, in Figures 3a to 3c In the illustration, subpixels 23 and touch blocks 2211 are shown in rectangular shapes; however, this does not constitute a limitation on the shapes of subpixels 23 and touch blocks 2211 provided in the embodiments of this disclosure.

[0110] The structure of the display substrate according to the embodiments of this disclosure will be further described below.

[0111] like Figure 4As shown, in some specific embodiments, the first electrode 231 of at least one sub-pixel 23 includes a plurality of strip electrodes 2311, and the plurality of strip electrodes 2311 of the same sub-pixel are separated by a plurality of slits F. The plurality of strip electrodes 2311 of the same sub-pixel 23 extend in approximately the same direction; in other words, the plurality of strip electrodes 2311 all extend approximately along a first direction or a second direction.

[0112] Figure 5 Schematic illustration Figure 3b The second diagram at position A in the middle is for clarity. Figure 5 Only the touch unit and touch line are shown, such as Figure 5 As shown, in some specific embodiments, at least one touch unit 221 includes a plurality of touch blocks 2211, combined with Figure 4 and Figure 5 As shown, at least one touch block 2211 is configured to correspond to at least one sub-pixel 23, and different touch blocks 2211 correspond to different sub-pixels 23.

[0113] For example, each touch unit 221 covers multiple rows and columns of sub-pixels 23, and each touch unit 221 may include multiple touch blocks 2211, with each touch block 2211 corresponding to a sub-pixel 23. The touch block 2211 is multiplexed as the second electrode of the corresponding sub-pixel 23. The second electrode and the first electrode 231 constitute the driving electrode of the sub-pixel 23. For example, the first electrode 231 can be a pixel electrode, and the second electrode can be a common electrode. The touch block 2211 has a flat structure; for example, the orthographic projection of the touch block 2211 onto the substrate 21 is approximately a rectangle or similar shape.

[0114] In some specific embodiments, the first direction and the second direction have a preset angle. The preset angle is configured such that, for two adjacent rows of sub-pixels 23, the driving electrode of one row of sub-pixels 23 can form a first domain electric field, and the driving electrode of the other row of sub-pixels 23 can form a second domain electric field. Furthermore, the directions of the first domain electric field and the second domain electric field are different. In the embodiments of this disclosure, the preset angle can be determined according to actual needs and is not limited herein.

[0115] In some specific embodiments, multiple subpixels 23 constitute multiple pixel units P, and at least one pixel unit P includes multiple subpixels 23 of different colors. For example, a pixel unit may include subpixels 23 of three colors, such as red subpixels, blue subpixels, and green subpixels. As another example, a pixel unit may include subpixels of four colors, such as red subpixels, blue subpixels, green subpixels, and white subpixels, etc.

[0116] In some specific embodiments, multiple touch blocks 2211 in the same touch unit 221 are divided into multiple groups. At least one group of touch blocks includes multiple touch blocks 2211. Multiple sub-pixels 23 corresponding to multiple touch blocks 2211 in at least one group of touch blocks belong to the same pixel unit P. Multiple sub-pixels 23 corresponding to touch blocks 2211 in different groups of touch blocks belong to different pixel units P. Multiple touch blocks 2211 in the same group of touch blocks are interconnected.

[0117] For example, a set of touch blocks includes three touch blocks 2211 (e.g., first touch block 2211b, second touch block 2211g, and third touch block 2211r), which cover a pixel unit P. The pixel unit P covered by the set of touch blocks includes three sub-pixels 23 (e.g., first sub-pixel 23b, second sub-pixel 23g, and third sub-pixel 23r). The three touch blocks 2211 in the set of touch blocks can be configured one-to-one with the three sub-pixels 23 of the pixel unit P covered by the set of touch blocks, and the three touch blocks 2211 are formed as a single structure. For example, the orthographic projection of the structure formed by the three touch blocks 2211 on the substrate 21 is approximately a rectangular shape.

[0118] In some specific embodiments, there are gaps between different groups of touch blocks, and touch blocks 2211 belonging to different groups in the same touch unit 221 are connected by a first connecting part 2212.

[0119] In this embodiment, the gap between different groups of touch blocks 2211 can be the first cutout structure and the third cutout structure mentioned below. By setting gaps between different groups of touch blocks 2211, a portion of the signal lines can be exposed, thereby reducing the parasitic capacitance formed between the touch blocks 2211 and the signal lines and reducing the impact of parasitic capacitance on the display. Specifically, this will be described in detail below, and will not be repeated here.

[0120] In this embodiment of the present disclosure, different groups of touch blocks 2211 in the same touch unit 221 are connected through the first connecting part 2212, thereby connecting all the touch blocks 2211 in the same touch unit 221 together, and enabling these touch blocks 2211 to be connected to the touch recognition module through one or more touch lines 24.

[0121] In some specific embodiments, multiple sets of touch blocks connected to the first connection portion 2212 are arranged around the first connection portion 2212.

[0122] For example, such as Figure 5 As shown, the multiple sets of touch blocks 2211 connected to the first connecting part 2212 may include four sets of touch blocks, namely, the four sets of touch blocks located at the upper left, lower left, upper right, and lower right of the first connecting part 2212.

[0123] In some specific embodiments, the plurality of subpixels 23 include a plurality of first subpixels 23b capable of displaying a first color; the plurality of touch blocks 2211 of at least one touch unit 221 include a plurality of first touch blocks 2211b; at least one first touch block 2211b is correspondingly disposed with at least one first subpixel 23b; different first touch blocks 2211b correspond to different first subpixels 23b; at least one touch line 24 includes a body portion 241 and a plurality of protrusions 242 located on one side of the body portion 241; the plurality of protrusions 242 are arranged along the length direction of the touch line 24; at least one protrusion 242 is correspondingly disposed with at least one first touch block 2211b; different protrusions 242 correspond to different first touch blocks 2211b; the orthographic projection of at least one protrusion 242 on the substrate 21 and the orthographic projection of its corresponding first touch block 2211b on the substrate 21 overlap. It should be noted that, in this embodiment, the protrusion 242 and the first touch block 2211b are disposed on different layers, and the protrusion 242 is disposed on the side of the first touch block 2211b closer to the substrate 21. Therefore, in Figure 5 In the middle, the portion where the protrusion 242 overlaps with the first touch block 2211b is blocked by the first touch block 2211b. In this way, the protrusion 242 can be connected to the corresponding first touch block 2211b through a through hole, thereby realizing the connection between the touch electrode 22 and the touch line 24.

[0124] For example, each touch line 24 includes a body portion 241 and a plurality of protrusions 242 located on one side of the body portion 241. The protrusions 242 are located on the left side of the body portion 241. Of course, in some other specific embodiments, the protrusions 242 may also be located on the right side of the body portion 241. The specific side of the body portion 241 where the protrusions 242 are located can be determined according to actual needs and is not limited here.

[0125] For example, the first touch block 2211b is arranged in a one-to-one correspondence with the first sub-pixel 23b, and the orthographic projection of each protrusion 242 on the substrate 21 and the orthographic projection of the corresponding first touch block 2211b on the substrate 21 are arranged to overlap.

[0126] In some specific embodiments, the touch line 24 is located on the side of the touch unit 221 closest to the substrate 21. At least one touch block 2211b in the touch unit 221 is arranged in an array, and at least a portion of at least one column of the first touch blocks 2211b in the touch unit 221 is connected through a via and a corresponding protrusion 242. For example, a portion of the first touch blocks 2211b in one column of the touch unit 221 is connected through a via and a corresponding protrusion 242; or, in multiple columns of the first touch blocks 2211b in the touch unit 221, a portion of each column is connected through a via and a corresponding protrusion 242. The specific connection can be determined according to actual needs and is not limited here.

[0127] In some specific embodiments, one of the first touch blocks 2211b in two adjacent rows is connected to the corresponding protrusion 242 through a via. For example, the first touch blocks 2211b in odd-numbered rows are connected to the corresponding protrusion 242 through vias, while the first touch blocks 2211b in even-numbered rows are spaced apart from their corresponding protrusions 242. Of course, it is also possible that the first touch blocks 2211b in even-numbered rows are connected to the corresponding protrusions 242 through vias, while the first touch blocks 2211b in odd-numbered rows are spaced apart from their corresponding protrusions 242. The specific configuration can be determined according to actual needs and is not limited here.

[0128] Figure 6 A schematic diagram illustrating the first electrode and signal line in an embodiment of this disclosure is shown, such as... Figure 6 As shown, in some specific embodiments, the display substrate further includes multiple rows of gate lines, and the sub-pixels 23 in the same row are connected to the same gate line. Figure 7 This schematically illustrates a diagram of the hollowed-out structure on the touch electrode in an embodiment of the present disclosure, in conjunction with... Figure 6 and Figure 7 As shown, the touch electrode 22 also includes multiple rows of first cutout structures 222, with at least one row of first cutout structures 222 corresponding to at least one row of gate lines, and different rows of first cutout structures 222 corresponding to different rows of gate lines. The orthographic projection of at least one row of first cutout structures 222 on the substrate 21 and the orthographic projection of the gate line corresponding to the first cutout structure 222 on the substrate 21 at least partially overlap.

[0129] In this embodiment, the first cutout structure can be configured one-to-one with the gate line. Each first cutout structure 222 can expose a portion of its corresponding gate line, thereby reducing the parasitic capacitance formed between the touch electrode 22 and the gate line. The shape of the first cutout structure 222 can be determined according to actual needs. For example, the first cutout structure 222 can be a strip-shaped cutout structure.

[0130] like Figure 6 As shown, in some specific embodiments, the first electrode 231 of at least one sub-pixel includes a plurality of strip electrodes 2311. The length of at least one strip electrode 2311 of at least one first sub-pixel 23b is less than the length of the plurality of strip electrodes 2311 of other sub-pixels 23. In this way, the overlap area between the first electrode 231 of the first sub-pixel 23b and the touch line 24 can be reduced, thereby reducing the parasitic capacitance between the first electrode 231 of the first sub-pixel 23b and the touch line 24.

[0131] In some specific embodiments, the first sub-pixel 23b is a blue sub-pixel 23. Since the blue sub-pixel 23 has lower luminous efficiency, the size of the strip electrode 2311 has little impact on the luminous brightness of the blue sub-pixel 23. Therefore, even if the size of the strip electrode 2311 is reduced, the blue sub-pixel 23 can still maintain good luminous performance. Of course, the multiple sub-pixels 23 also include a second sub-pixel 23g and a third sub-pixel 23r. The second sub-pixel 23g can be green, and the third sub-pixel 23r can be red.

[0132] In some specific embodiments, the display substrate further includes multiple rows of data lines Data, and at least one subpixel 23 further includes a thin-film transistor T connected to the data lines Data. In the embodiments of this disclosure, the thin-film transistor T can be a top-gate structure or a bottom-gate structure, which can be determined according to actual needs and is not limited here. The following description uses a bottom-gate structure for the thin-film transistor T as an example to illustrate the thin-film transistor T in the embodiments of this disclosure. Figure 8 A cross-sectional view of a thin-film transistor in an embodiment of this disclosure is schematically shown, such as... Figure 8As shown, in some specific embodiments, the thin-film transistor T includes a semiconductor layer T1 disposed on a substrate 21 and a gate layer T2 disposed on the side of the semiconductor layer T1 away from the substrate 21. The gate layer T2 can be formed integrally with the gate line. The semiconductor layer T1 includes a first electrode connection portion T11, a second electrode connection portion T12, and a channel portion T13 located between the first electrode connection portion T11 and the second electrode connection portion T12. One of the first electrode connection portion T11 and the second electrode connection portion T12 is connected to the source S of the thin-film transistor T, and the other is connected to the drain D of the thin-film transistor T. The channel portion T13 is disposed opposite to the gate layer T2, and the channel portion T13 has a line-shaped structure. For example, the channel portion T13 of the thin-film transistor T can be arranged along... Figure 6 A third-party extension within.

[0133] Combination Figure 6 and Figure 7 As shown, the touch electrode 22 also includes a plurality of second cutout structures 223, at least one second cutout structure 223 being correspondingly disposed with at least one sub-pixel 23, and different second cutout structures 223 corresponding to different sub-pixels 23. Furthermore, the orthographic projection of at least one second cutout structure 223 on the substrate 21 and the orthographic projection of the thin-film transistor T of the sub-pixel 23 corresponding to the second cutout structure 223 on the substrate 21 at least partially overlap. In other words, the second cutout structure 223 can expose at least a portion of the thin-film transistor T of its corresponding sub-pixel 23, thereby reducing the parasitic capacitance formed between the touch electrode 22 and the thin-film transistor T.

[0134] For example, the second cutout structure 223 can be configured one-to-one with the sub-pixel 23. The orthographic projection of each second cutout structure 223 on the substrate 21 and the orthographic projection of the thin film transistor T of the sub-pixel 23 corresponding to the second cutout structure 223 on the substrate 21 at least partially overlap, thereby minimizing the parasitic capacitance formed between the touch electrode 22 and the thin film transistor T.

[0135] In some specific embodiments, subpixels 23 in the same column are connected to the same data line. Subpixels 23 include a first side and a second side that are positioned opposite each other, i.e. Figure 6On the left and right sides of each sub-pixel, the orthographic projection of at least one column of data lines Data on the substrate 21 lies on the first side of the orthographic projection of the sub-pixel 23 connected to the data line Data on the substrate 21. For each column of data lines Data, the data line Data is divided into multiple segments, at least one segment including a first portion corresponding to odd-numbered rows of sub-pixels 23 and a second portion corresponding to even-numbered rows of sub-pixels 23. The first portion and the first electrode 231 of their corresponding sub-pixels 23 extend in substantially the same direction, and the second portion and the first electrode 231 of their corresponding sub-pixels 23 extend in substantially the same direction. Adjacent segments in each column of data lines Data are connected by a second connecting portion 25, which bends towards a third direction, the direction being from the second side of the sub-pixel 23 to the first side of the sub-pixel 23.

[0136] In this embodiment, the second connecting portion 25 can be bent to the left or to the right, depending on actual needs, and is not limited herein. The second connecting portion 25 allows for better bending of the data line Data, ensuring that the extension direction of the data line Data is approximately the same as the extension direction of the first electrode 231 of the sub-pixel 23 connected to it. Furthermore, the bending of the second connecting portion 25 in a third direction helps to ensure a sufficiently large distance between the first and second electrodes of the thin-film transistor T, thereby facilitating that the dimensions of the channel portion of the thin-film transistor T in the sub-pixel 23 meet the corresponding design requirements.

[0137] In some specific embodiments, the touch electrode 22 further includes multiple rows of third hollow structures 224, with at least one row of third hollow structures 224 corresponding to at least one touch line 24, and different rows of third hollow structures 224 corresponding to different touch lines 24. The at least one row of third hollow structures 224 includes: a plurality of second hollow portions 2241 spaced apart along the extending direction of the third hollow structure 224, and a third hollow portion 2242 located on one side of at least one second hollow portion 2241. At least one third hollow portion 2242 is corresponding to at least one protrusion 242 of a corresponding touch line 24, and different third hollow portions 2242 correspond to different protrusions 242. The orthographic projection of at least one third hollow portion 2242 on the substrate 21 and the orthographic projection of its corresponding protrusion 242 on the substrate 21 partially overlap. At least one second cutout portion 2241 is orthogonally projected onto the substrate 21 and the corresponding touch line 24 body portion 241 is orthogonally projected onto the substrate 21. In other words, the third cutout structure 224 can expose the touch line 24, thereby reducing the size of the parasitic capacitance formed between the touch unit 221 and the touch line 24.

[0138] For example, each column of third cutout structures 224 includes multiple second cutout portions 2241 and multiple third cutout portions 2242. The multiple second cutout portions 2241 are spaced apart from each other. The orthographic projection of the second cutout portion 2242 on the substrate 21 at least partially overlaps with the orthographic projection of the body portion 241 of the corresponding touch line 24 on the substrate 21. In other words, the second cutout portion 2241 can expose at least a portion of the body portion 241 of the corresponding touch line 24, thereby reducing the parasitic capacitance between the touch electrode 22 and the touch line 24. Each third cutout portion 2242 is correspondingly provided with a protrusion 242 of the corresponding touch line 24. The orthographic projection of each third cutout portion 2242 on the substrate 21 and the orthographic projection of its corresponding protrusion 242 on the substrate 21 partially overlap, thereby greatly reducing the size of the parasitic capacitance formed between the touch unit 221 and the touch line 24.

[0139] In some specific embodiments, for at least one column of third cutout structures 224, the j-th third cutout portion 2242 is connected to the first cutout structure 222 and spaced apart from the second cutout portion 2241. The (j+1)-th third cutout portion 2242 is spaced apart from the first cutout structure 222 and connected to the second cutout portion 2241, where j is a positive integer. Thus, for the j-th third cutout portion 2242, since it is connected to the first cutout structure 222, the width of the portion used for connection between the second connecting portion 25 and the touch block 2211 can be easily set to be larger, which is beneficial for reducing the resistance of the touch unit 221. And for the (j+1)-th third cutout portion 2242, since it is connected to the second cutout portion 2241, it is beneficial to set a via, so that the protrusion 242 of the touch line 24 can be connected to the corresponding touch block 2211 through the via.

[0140] The specific manner in which the touch unit 221 covers the sub-pixel 23 in the embodiments of this disclosure will be described below.

[0141] In some specific embodiments, multiple touch units 221 are arranged in an array, and the number of rows of subpixels 23 covered by touch units 221 in the same row is the same.

[0142] In some specific embodiments, the number of rows of subpixels covered by each row of the touch unit is the same.

[0143] For example, Figure 9a A schematic diagram of a display substrate according to an embodiment of the present disclosure is shown in Figure 4. Figure 9aAs shown, the display substrate has a resolution of 720*1600, and 32 rows of touch units 221 can be arranged in the display substrate, wherein each touch unit 221 can cover 50 rows of sub-pixels 23. Optionally, the display substrate can have 18 columns of touch units 221, wherein each touch unit 221 can cover 40 rows of sub-pixels 23.

[0144] In some specific embodiments, at least two rows of touch units 221 cover different numbers of subpixels 23. For example, adjacent rows of touch units 221 may cover different numbers of subpixels 23, or multiple rows of touch units 221 may be divided into multiple groups, each group including multiple rows of adjacent touch units 221, with different groups of touch units 221 covering different numbers of subpixels 23.

[0145] In some specific embodiments, the number of rows of subpixels 23 covered by at least one row of touch units 221 in the first n rows is different from the number of rows of subpixels 23 covered by at least one row of touch units 221 in rows n+1 to m. And / or, the number of rows of subpixels 23 covered by at least one row of touch units 221 in rows n+1 to m is different from the number of rows of subpixels 23 covered by at least one row of touch units 221 in rows m+1 to N. Here, N is the total number of rows of touch units 221, m and n are both integers, and 1 ≤ n < m < N.

[0146] In this embodiment of the disclosure, the touch unit 221 and the subpixel touch unit 221 are arranged in the manner described above. The touch unit 221 in the middle part of the display substrate can adopt the most efficient arrangement method, while at the top or bottom of the display substrate, the touch unit 221 can adopt a more flexible arrangement method, so as to better adapt to the various requirements of the display substrate, such as irregular display.

[0147] In some specific embodiments, n and m satisfy the following relationship:

[0148] twenty one% 2%; and / or,

[0149] n and N satisfy the following relationship:

[0150] 16% 3%; and / or,

[0151] m and N satisfy the following relationship:

[0152] 97% 75%.

[0153] For example, when N = 32, n can be any value from 1 to 5, and m can be any value from 25 to 31.

[0154] In some specific embodiments, the multiple touch units 221 satisfy the following relationships: y < x and y < z; or y > x and y < z; or y > x and y > z. Here, x is the number of rows of sub-pixels 23 covered by at least one row of touch units 221 among the touch units 221 in the first n rows, y is the number of rows of sub-pixels 23 covered by at least one row of touch units 221 among the touch units 221 in the (n + 1)-th to m-th rows, and z is the number of rows of sub-pixels 23 covered by at least one row of touch units 221 among the touch units 221 in the (m + 1)-th to N-th rows.

[0155] For example, Figure 9b FIG. 5 schematically shows a schematic diagram of a display substrate according to an embodiment of the present disclosure. As Figure 9b shown, the display substrate has a resolution of 720*1540. In the display substrate, 32 rows of touch units 221 can be provided. Among the touch units 221 in the first row and the 32nd row, each touch unit 221 covers 50 rows of sub-pixels 23. Among the touch units 221 in the 2nd to 31st rows, each touch unit 221 covers 48 rows of sub-pixels 23. Optionally, 18 columns of touch units 221 can be provided in the display substrate. For example, each touch unit 221 can cover 40 columns of sub-pixels 23.

[0156] For example, the display substrate has a resolution of 720*1520. In the display substrate, 32 rows of touch units 221 can be provided. Among the touch units 221 in the first to 4th rows, each touch unit 221 covers 46 rows of sub-pixels 23. Among the touch units 221 in the 5th to 28th rows, each touch unit 221 covers 48 rows of sub-pixels 23. Among the touch units 221 in the 29th to 32nd rows, each touch unit 221 covers 46 rows of sub-pixels 23. Optionally, 18 columns of touch units 221 can be provided in the display substrate. For example, each touch unit 221 can cover 40 columns of sub-pixels 23.

[0157] For example, the display substrate has a resolution of 720*1612. In the display substrate, 32 rows of touch units 221 can be provided. Among the touch units 221 in the first to 3rd rows, each touch unit 221 covers 52 rows of sub-pixels 23. Among the touch units 221 in the 4th to 29th rows, each touch unit 221 covers 50 rows of sub-pixels 23. Among the touch units 221 in the 29th to 32nd rows, each touch unit 221 covers 52 rows of sub-pixels 23. Optionally, 18 columns of touch units 221 can be provided in the display substrate. For example, each touch unit 221 can cover 40 columns of sub-pixels 23.

[0158] For example, the display substrate adopts a 720*1680 resolution, and 32 rows of touch units 221 can be arranged in the display substrate. Each touch unit 221 has sub-pixels 23. Specifically, in rows 1 to 4, each touch unit 221 covers 54 rows of sub-pixels 23; in rows 5 to 28, each touch unit 221 covers 52 rows of sub-pixels 23; and in rows 29 to 32, each touch unit 221 covers 54 rows of sub-pixels 23. Optionally, 18 columns of touch units 221 can be arranged in the display substrate, for example, each touch unit 221 can cover 40 columns of sub-pixels 23.

[0159] In some specific embodiments, in the touch units 221 from the (n+1)th to the mth row, the number of rows of subpixels 23 covered by two adjacent rows of touch units 221 is different.

[0160] For example, Figure 9c A schematic diagram of a display substrate according to an embodiment of the present disclosure is shown in Figure 6. Figure 9c As shown, the display substrate adopts a resolution of 720*1560. The display substrate can be arranged with 32 rows of touch units 221. Among them, in the 1st to 5th rows of touch units 221, each touch unit 221 covers 48 rows of sub-pixels 23. In the 6th to 24th rows of touch units 221, the even-numbered rows of touch units 221 cover 50 rows of sub-pixels 23. In the 7th to 25th rows of touch units 221, the odd-numbered rows of touch units 221 cover 48 rows of sub-pixels 23. In the 26th to 31st rows of touch units 221, each touch unit 221 covers 48 rows of sub-pixels 23. In the 32nd row of touch units 221, each touch unit 221 covers 52 rows of sub-pixels 23.

[0161] In some specific embodiments, the number of rows of subpixels 23 covered by the Nth row of touch units 221 is different from the number of rows of subpixels 23 covered by other rows of touch units 221, thereby making the arrangement of the last row of touch units 221 more flexible, and thus enabling the touch units 221 to adapt to the needs of functions such as irregular display in the display substrate.

[0162] In some specific embodiments, each touch unit 221 covers the same number of columns of subpixels; for example, each touch unit 221 covers 40 columns of subpixels 23. Alternatively,

[0163] In the (m+1)th row of touch units 221 to the Nth row of touch units 221, the number of columns of sub-pixels 3 covered by at least one touch unit 221 in at least one row of touch units 221 is different from the number of columns of sub-pixels 23 covered by touch units 221 in other rows.

[0164] For example, the display substrate adopts a resolution of 720*1612, and 32 rows of touch units 221 can be arranged in the display substrate. Among them, in the 1st to 5th rows of touch units 221, each touch unit 221 covers 48 rows of sub-pixels 23; in the 6th to 24th rows of touch units 221, the even-numbered rows of touch units 221 cover 48 rows of sub-pixels 23; in the 7th to 25th rows of touch units 221, the odd-numbered rows of touch units 221 cover 50 rows of sub-pixels 23; in the 26th to 31st rows of touch units 221, each touch unit 221 covers 48 rows of sub-pixels 23; and in the 32nd row of touch units 221, each touch unit 221 covers 52 rows of sub-pixels 23. Optionally, 18 columns of touch units 221 can be provided in the display substrate. For example, except for the touch units 221 in the last row, each of the remaining touch units 221 in the display substrate covers 40 columns of sub-pixels 23, and each of the touch units 221 in the last row covers 38 columns of sub-pixels 23.

[0165] In this way, the size of the Nth row touch unit 221 can be adapted to irregular structures set at the edge of the display area AA, such as openings for cameras.

[0166] In the touch units from row m+1 to row N, at least one row of touch units includes a plurality of touch units comprising:

[0167] In some specific embodiments, there is at least one first touch unit and at least one second touch unit, wherein the orthographic projection of the first touch unit on the substrate is different from the orthographic projection of the second touch unit on the substrate; wherein the number of columns of the sub-pixels covered by the first touch unit is different from the number of columns of the sub-pixels covered by the second touch unit, and the number of columns of the sub-pixels covered by the first touch unit is different from the number of columns of the sub-pixels covered by the touch units located in other rows.

[0168] For example, the orthographic projection of the first touch unit on the substrate can be irregular (e.g., non-rectangular), and the orthographic projection of the second touch unit on the substrate can be similar to a rectangle, thereby making the Nth row touch unit 221 more suitable for adapting to the irregular structure set at the edge of the display area AA.

[0169] In some specific embodiments, for two adjacent rows of touch units, the number of subpixels covered by one row of touch units is c, and the number of subpixels covered by the other row of touch units is d, wherein c is less than d, and c and d satisfy the following relationship:

[0170] 80%.

[0171] In this way, in this embodiment, the size of two adjacent rows of touch units 221 is adjustable within a certain range. This allows for more flexible size settings for the touch units 221 while ensuring that the pattern differences between the two adjacent rows of touch units 221 are not too large.

[0172] In some specific embodiments, for two adjacent rows of touch units 221, the area of ​​each touch unit 221 in one row is greater than e, and the area of ​​each touch unit 221 in the other row is greater than f, wherein e is less than f, and e and f satisfy the following relationship:

[0173] 92%.

[0174] For example, if the reference area is q, the area range of the touch unit 221 can be set from 90%*q to 96%*q.

[0175] In some specific embodiments, the display substrate can be applied to various current display fields, and the specific application can be determined according to actual needs, without limitation. For example, the display substrate of this disclosure can be applied to the fields of virtual reality (VR) display and augmented reality (AR) display.

[0176] The display substrate disclosed herein can be an organic light-emitting diode (OLED) display substrate, or a quantum dot light-emitting diode (QLED) display substrate, or a sub-millimeter light-emitting diode (mini LED) display substrate, or a micro light-emitting diode (micro LED) display substrate, etc.

[0177] In embodiments of this disclosure, the display substrate may further include an encapsulation layer disposed over the display substrate. For example, the encapsulation layer may include a first encapsulation sublayer, a second encapsulation sublayer, and a third encapsulation sublayer disposed sequentially in a direction away from the substrate. For example, the first and third encapsulation sublayers may be made of inorganic materials, and the second encapsulation sublayer may be made of organic materials.

[0178] The TFE encapsulation layer can prevent moisture and oxygen from penetrating into the display substrate, thus protecting the display substrate.

[0179] This disclosure also provides a display device, which includes the display substrate described above.
