As a result, not only can the image contrast of transmissive display products using this backlight source reach the level of organic light-emitting diode (OLED) display products, but the product can also retain the technical advantages of liquid crystal display, thereby improving the display effect of the picture and providing users with a better visual experience. Summary of the invention

There is a relative translation spacing, and the translation spacing is smaller than the spacing between two adjacent light-emitting units in the same column in the column direction, so that each light-emitting unit in the Nth column light-emitting unit and the N+1th column light-emitting unit is respectively located in different rows in sequence, wherein N and k are both positive integers greater than 0; the first drive signal line group is located between the Nth column light-emitting unit and the N+1th column light-emitting unit, and extends in a zigzag manner along the column direction and alternately passes through the Mth row and Nth column light-emitting unit, the M+1th row and N+1th column light-emitting unit and the M+2th row and Nth column light-emitting unit, so as to provide the first electrode signal to each light-emitting unit in the Nth column light-emitting unit and the N+1th column light-emitting unit, wherein M is a positive integer greater than 0, and each of the light-emitting units has two adjacent first drive signal line groups passing through.

[0004] For example, in the light-emitting substrate provided in an embodiment of the present disclosure, between the light-emitting units in the Nth column and the light-emitting units in the N+1th column, the first drive signal line group extends approximately along a straight line between two light-emitting units located in two adjacent rows.

[0005] For example, in the light-emitting substrate provided in an embodiment of the present disclosure, the translation spacing is equal to 1 / 2 of the spacing between two adjacent light-emitting units in the same column in the column direction, and between the light-emitting unit in the Nth column and the light-emitting unit in the N+1th column, the angle of the extension direction of the first drive signal line group between the light-emitting unit in the Mth row and the Nth column and the light-emitting unit in the M+1th row and the N+1th column relative to the row direction is equal to the angle of the extension direction of the first drive signal line group between the light-emitting unit in the M+1th row and the N+1th column and the light-emitting unit in the M+2th row and the Nth column relative to the row direction.

[0007] For example, in the light-emitting substrate provided in an embodiment of the present disclosure, the multiple light-emitting sub-units in each of the light-emitting units include a first light-emitting sub-unit and a second light-emitting sub-unit, and the first light-emitting sub-unit and the second light-emitting sub-unit are arranged adjacent to each other in the row direction; the at least one first driving signal line in each of the first driving signal line groups includes a first light-emitting signal line corresponding to the first light-emitting sub-unit and a second light-emitting signal line corresponding to the second light-emitting sub-unit, the first light-emitting signal line is configured to be connected to the first electrode end of the first light-emitting sub-unit to provide a first electrode signal corresponding to the first light-emitting sub-unit, and the second light-emitting signal line is configured to be connected to the first electrode end of the second light-emitting sub-unit to provide a first electrode signal corresponding to the second light-emitting sub-unit; between the light-emitting units in the Nth column and the light-emitting units in the N+1th column, the first light-emitting signal line in the first driving signal line group is connected to the first light-emitting sub-unit in each light-emitting unit in the Nth column, and the second light-emitting signal line in the first driving signal line group is connected to the second light-emitting sub-unit in each light-emitting unit in the N+1th column.

[0008] For example, in the light-emitting substrate provided in an embodiment of the present disclosure, in each of the first driving signal line groups, the first light-emitting signal line and the second light-emitting signal line are arranged sequentially along the row direction from the second light-emitting sub-unit in each light-emitting unit to the first light-emitting sub-unit.

[0009] For example, in the light-emitting substrate provided in one embodiment of the present disclosure, between the light-emitting units in the N+1th column and the light-emitting units in the N+2th column, the first light-emitting signal line in the first drive signal line group is connected to the first light-emitting sub-unit in each light-emitting unit in the N+1th column, and the second light-emitting signal line in the first drive signal line group is connected to the second light-emitting sub-unit in each light-emitting unit in the N+2th column.

[0010] For example, in the light-emitting substrate provided in an embodiment of the present disclosure, the multiple light-emitting sub-units in each of the light-emitting units also include a third light-emitting sub-unit, and the third light-emitting sub-unit is arranged in parallel with the first light-emitting sub-unit and the second light-emitting sub-unit in the column direction; the at least one first driving signal line in each of the first driving signal line groups also includes a third light-emitting signal line corresponding to the third light-emitting sub-unit, and the third light-emitting signal line is configured to be connected to the first electrode end of the third light-emitting sub-unit to provide a first electrode signal corresponding to the third light-emitting sub-unit; between the light-emitting units in the Nth column and the N+1th column, the third light-emitting signal line in the first driving signal line group is connected to the third light-emitting sub-unit in each light-emitting unit in the Nth column, or is connected to the third light-emitting sub-unit in each light-emitting unit in the N+1th column.

[0011] For example, in the light-emitting substrate provided in one embodiment of the present disclosure, between the light-emitting units in the Nth column and the light-emitting units in the N+1th column, the third light-emitting signal line in the first drive signal line group is connected to the third light-emitting sub-unit in each light-emitting unit in the N+1th column; between the light-emitting units in the N+1th column and the light-emitting units in the N+2th column, the third light-emitting signal line in the first drive signal line group is connected to the third light-emitting sub-unit in each light-emitting unit in the N+2th column.

[0012] For example, in the light-emitting substrate provided in an embodiment of the present disclosure, the second light-emitting sub-unit, the third light-emitting sub-unit and the first light-emitting sub-unit are arranged sequentially in the row direction, and in each of the first driving signal line groups, the first light-emitting signal line, the second light-emitting signal line and the third light-emitting signal line are arranged sequentially along the row direction from the second light-emitting sub-unit in each of the light-emitting units to the first light-emitting sub-unit.

[0013] For example, in the light-emitting substrate provided in an embodiment of the present disclosure, the first light-emitting sub-unit, the second light-emitting sub-unit and the third light-emitting sub-unit are respectively configured to provide light of different colors.

[0014] For example, the light-emitting substrate provided in one embodiment of the present disclosure also includes multiple second drive signal line groups, which extend along the row direction and correspond one-to-one to the multiple rows of light-emitting units, respectively. Each of the second drive signal line groups includes at least one second drive signal line, and the second drive signal line is configured to be connected to the second electrode end of the light-emitting sub-unit to provide a second electrode signal.

[0015] For example, in the light-emitting substrate provided in an embodiment of the present disclosure, the at least one second driving signal line in each of the second driving signal line groups includes a fourth light-emitting signal line corresponding to the third light-emitting sub-unit and a fifth light-emitting signal line corresponding to the first light-emitting sub-unit, the fourth light-emitting signal line is configured to be connected to the second electrode end of the third light-emitting sub-unit to provide a second electrode signal corresponding to the third light-emitting sub-unit, and the fifth light-emitting signal line is configured to be connected to the second electrode end of the first light-emitting sub-unit to provide a second electrode signal corresponding to the first light-emitting sub-unit.

[0016] For example, in the light-emitting substrate provided in an embodiment of the present disclosure, the at least one second drive signal line in each of the second drive signal line groups also includes a sixth light-emitting signal line corresponding to the second light-emitting sub-unit, and the sixth light-emitting signal line is configured to be connected to the second electrode end of the second light-emitting sub-unit to provide a second electrode signal corresponding to the second light-emitting sub-unit, and in each of the second drive signal line groups, the sixth light-emitting signal line is located between the fourth light-emitting signal line and the fifth light-emitting signal line in the column direction.

[0017] For example, in the light-emitting substrate provided in one embodiment of the present disclosure, in each of the second driving signal line groups, the sixth light-emitting signal line is connected to the fifth light-emitting signal line through a connecting portion located between the sixth light-emitting signal line and the fifth light-emitting signal line, and the fifth light-emitting signal line, the sixth light-emitting signal line and the connecting portion are integrally arranged.

[0018] For example, in the light-emitting substrate provided in an embodiment of the present disclosure, each of the second driving signal line groups also includes a plurality of groups of conductive parts corresponding one by one to each light-emitting unit in a row of light-emitting units, and each group of the conductive parts includes a first conductive part and a second conductive part; the first conductive part is connected to the fourth light-emitting signal line and extends from the fourth light-emitting signal line toward a side close to the third light-emitting sub-unit in the light-emitting unit corresponding to the first conductive part, so that the orthographic projection of the first conductive part on the substrate substrate at least partially overlaps with the orthographic projection of the third light-emitting sub-unit in the corresponding light-emitting unit on the substrate substrate; the second conductive part is connected to the fifth light-emitting signal line and extends from the fifth light-emitting signal line toward a side close to the first light-emitting sub-unit in the light-emitting unit corresponding to the second conductive part, so that the orthographic projection of the second conductive part on the substrate substrate at least partially overlaps with the orthographic projection of the first light-emitting sub-unit in the corresponding light-emitting unit on the substrate substrate.

[0019] For example, the light-emitting substrate provided by an embodiment of the present disclosure also includes multiple conductive structures corresponding one-to-one to the multiple light-emitting units, and the orthographic projection of each of the light-emitting units on the base substrate is located within the area surrounded by the outer contour of the orthographic projection of the conductive structure corresponding to the light-emitting unit on the base substrate; along the direction from the center to the edge of each of the conductive structures, the conductive structure is divided into multiple regions, and the transmittance of each region of the conductive structure is different from each other.

[0020] For example, in the light-emitting substrate provided in an embodiment of the present disclosure, the shapes of the orthographic projections of the plurality of conductive structures on the base substrate are substantially the same as each other, and the orthographic projections of the plurality of conductive structures on the base substrate do not overlap with each other.

[0021] For example, in the light-emitting substrate provided in an embodiment of the present disclosure, along the direction from the center to the edge of each of the conductive structures, the light transmittance of multiple regions of the conductive structure gradually increases.

[0022] For example, in the light-emitting substrate provided in an embodiment of the present disclosure, each of the conductive structures is a centrally symmetrical structure.

[0023] For example, in the light-emitting substrate provided in an embodiment of the present disclosure, each of the conductive structures includes a first conductive substructure and a second conductive substructure opposite to each other in the column direction, the first conductive substructure and the second conductive substructure are axially symmetrical along the row direction relative to the center of the conductive structure to form the conductive structure, the first conductive substructure and the second conductive substructure are spaced and insulated from each other, the orthographic projection of the first conductive substructure on the substrate substrate is located on the side of the orthographic projection of the fourth light-emitting signal line on the substrate substrate away from the orthographic projection of the fifth light-emitting signal line on the substrate substrate, and the orthographic projection of the second conductive substructure on the substrate substrate is located on the side of the orthographic projection of the fifth light-emitting signal line on the substrate substrate away from the orthographic projection of the fourth light-emitting signal line on the substrate substrate.

[0024] For example, in the light-emitting substrate provided in an embodiment of the present disclosure, the first conductive substructure is connected to the fourth light-emitting signal line, and the second conductive substructure is connected to the fifth light-emitting signal line.

[0025] For example, in the light-emitting substrate provided in an embodiment of the present disclosure, the first conductive substructure is integrally provided with the fourth light-emitting signal line, and the second conductive substructure is integrally provided with the fifth light-emitting signal line.

[0026] For example, in the light-emitting substrate provided in an embodiment of the present disclosure, the first conductive substructure includes a plurality of first semi-annular parts arranged in sequence along the direction from the center of each conductive structure to the edge, and the two ends of each of the first semi-annular parts are respectively connected to the fourth signal line, so that two adjacent first semi-annular parts are electrically connected to each other and form an opening area, and among the plurality of first semi-annular parts, the distance between two adjacent first semi-annular parts located in different areas of the conductive structure gradually increases along the direction from the center of each conductive structure to the edge; the second conductive substructure includes a plurality of second semi-annular parts arranged in sequence along the direction from the center of each conductive structure to the edge, and the two ends of each of the second semi-annular parts are respectively connected to the fifth signal line, so that two adjacent second semi-annular parts are electrically connected to each other and form an opening area, and among the plurality of second semi-annular parts, the distance between two adjacent second semi-annular parts located in different areas of the conductive structure gradually increases along the direction from the center of each conductive structure to the edge.

[0027] For example, in the light-emitting substrate provided in an embodiment of the present disclosure, the spacing in the row direction between the orthographic projection of the Nth column of light-emitting units on the base substrate and the orthographic projection of the N+1th column of light-emitting units on the base substrate is greater than 0.

[0028] For example, in the light-emitting substrate provided in an embodiment of the present disclosure, the spacing between the orthographic projections of two adjacent columns of light-emitting units on the substrate in the row direction is equal to the spacing between the orthographic projections of two adjacent rows of light-emitting units on the substrate in the column direction.

[0029] For example, in the light-emitting substrate provided in an embodiment of the present disclosure, each of the first driving signal lines in the first driving signal line group is connected to the first electrode terminal of a light-emitting sub-unit in the light-emitting unit through which the first driving signal line group passes.

[0030] At least one embodiment of the present disclosure further provides a display device, which includes a display panel and the light-emitting substrate described in any embodiment of the present disclosure; the display panel has a display side and a non-display side, the light-emitting substrate is arranged on the non-display side of the display panel, and the multiple light-emitting units and the multiple first drive signal line groups are located on the side of the base substrate away from the display panel.

[0031] For example, a display device provided by an embodiment of the present disclosure further includes a reflective layer, and the reflective layer is located on a side of the light-emitting substrate away from the display panel.

[0032] At least one embodiment of the present disclosure further provides an electronic device, which includes the display device described in any embodiment of the present disclosure. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0048] Unless otherwise defined, the technical terms or scientific terms used in the present disclosure should be understood by people with ordinary skills in the field to which the present disclosure belongs. The "first", "second" and similar words used in the present disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. Similarly, similar words such as "one", "one" or "the" do not indicate quantity restrictions, but indicate that there is at least one. Similar words such as "include" or "comprise" mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Similar words such as "connect" or "connected" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0049] In display products using light-emitting diodes, mini light-emitting diodes or micro light-emitting diodes are small in size and high in brightness, and can be widely used in display products such as backlight modules, and the backlight can be finely adjusted to achieve the display of high dynamic range images. For example, the typical size of a micro light-emitting diode does not exceed 50μm, such as 10μm to 50μm; the typical size of a mini light-emitting diode is 50μm to 150μm, such as 80μm to 120μm. The backlight module composed of the above-mentioned mini light-emitting diodes or micro light-emitting diodes can be arranged on the non-display side of the display device in the display product, and the mini light-emitting diodes or micro light-emitting diodes in the backlight module can, for example, directly emit light facing the display device, thereby forming a top-emitting structure; or, the mini light-emitting diodes or micro light-emitting diodes in the backlight module can, for example, also emit light toward the side away from the display device, and reflect the light emitted by the mini light-emitting diodes or micro light-emitting diodes to the display device through a structure with a reflective function such as a reflective layer, thereby forming a reflective (e.g., downward-emitting) light-emitting structure.

[0050] In display products using mini LEDs or micro LEDs and adopting a reflective light-emitting structure, due to the addition of structures such as a reflective layer, the thicker diffusion film structure in the display product is usually removed to reduce the overall thickness of the display product and achieve an ultra-thin display. However, due to the removal of the diffusion film structure in the display product, the light emitted by the mini LEDs or micro LEDs is difficult to be well dispersed, resulting in poor uniformity of the light provided by the entire backlight module to the display device, causing optical defects and bringing serious adverse effects on the display effect of the display product.

[0051] At least one embodiment of the present disclosure provides a light-emitting substrate, which includes a base substrate, a plurality of light-emitting units and a plurality of first drive signal line groups located on the base substrate; each light-emitting unit includes a plurality of light-emitting sub-units, each light-emitting sub-unit includes a first electrode end and a second electrode end with a polarity opposite to the first electrode end; each first drive signal line group includes at least one first drive signal line, and the first drive signal line is configured to be connected to the first electrode end of the light-emitting sub-unit to provide a first electrode signal; the plurality of light-emitting units are arranged into a plurality of columns and a plurality of rows along the row direction and the column direction, respectively; in the light-emitting units in the Nth column and the N+1th column, the kth light-emitting unit in the Nth column and the kth light-emitting unit in the N+1th column are spaced apart from each other. There is a relative translation spacing in the column direction, and the translation spacing is smaller than the spacing in the column direction between two adjacent light-emitting units in the same column, so that each light-emitting unit in the Nth column and the N+1th column is respectively located in different rows in sequence, and N and k are both positive integers greater than 0; the first drive signal line group is located between the Nth column and the N+1th column, and extends in a zigzag manner along the column direction and alternately passes through the Mth row and Nth column light-emitting unit, the M+1th row and N+1th column light-emitting unit, and the M+2th row and Nth column light-emitting unit, so as to provide a first electrode signal to each light-emitting unit in the Nth column and the N+1th column light-emitting unit, and M is a positive integer greater than 0; each light-emitting unit has two adjacent first drive signal line groups passing through it.

[0052] In the light-emitting substrate provided in the above-mentioned embodiment of the present disclosure, for the adjacent N-th column of light-emitting units and the N+1-th column of light-emitting units (for example, the N-th column of light-emitting units and the N+1-th column of light-emitting units may be any two adjacent columns of light-emitting units in a plurality of light-emitting units, such as the first column of light-emitting units and the second column of light-emitting units, the second column of light-emitting units and the third column of light-emitting units, the third column of light-emitting units and the fourth column of light-emitting units, etc.), the k-th light-emitting unit in the N-th column of light-emitting units and the k-th light-emitting unit in the N+1-th column of light-emitting units have a relative translation spacing in the column direction, and the translation spacing is smaller than the translation spacing of the light-emitting units in the same column. The spacing between two adjacent light-emitting units in the column direction is determined, so that the light-emitting units in the two adjacent columns are arranged in an interlaced manner in the column direction, so that the light-emitting units in the two adjacent columns are respectively located in different rows along the column direction; and the first driving signal line group for providing the first electrode signal to the light-emitting sub-units in the light-emitting unit is extended along the column direction between the adjacent Nth column light-emitting unit and the N+1th column light-emitting unit and alternately passes through the Mth row and Nth column light-emitting unit, the M+1th row and N+1th column light-emitting unit and the M+2th row and Nth column light-emitting unit, thereby alternately passing through the light-emitting units in the two adjacent columns. Furthermore, each light-emitting unit or each column of light-emitting units can have two adjacent first driving signal line groups passing through, so that the multiple first driving signal line groups extending along the column direction between each two adjacent columns of light-emitting units form a wiring structure similar to a grid on the substrate, thereby achieving a uniform arrangement effect in a plane parallel to the main surface of the substrate. Therefore, by utilizing the uniform grid-like arrangement design formed by the first drive signal line group on the base substrate, each first drive signal line in the first drive signal line group can select to pass or block the light passing through the base substrate, thereby improving the uniformity of light selection, thereby improving the uniformity of the emitted light of the light-emitting substrate, and improving the light uniformity of the entire light-emitting substrate.

[0053] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. It should be noted that the same reference numerals in different drawings will be used to refer to the same elements that have been described.

[0054] Figure 1 A schematic plan view of a light-emitting substrate provided in some embodiments of the present disclosure. Figure 1As shown, the light-emitting substrate 10 includes a base substrate 101 and a plurality of light-emitting units 201 and a plurality of first drive signal line groups 301 located on the base substrate 101. Each light-emitting unit 201 includes a plurality of light-emitting subunits 210, and each light-emitting subunit 210 includes a first electrode terminal and a second electrode terminal with a polarity opposite to that of the first electrode terminal. For example, one of the first electrode terminal and the second electrode terminal of the light-emitting subunit 210 can be an anode terminal and the other can be a cathode terminal. Each first drive signal line group 301 includes at least one first drive signal line 310, and the first drive signal line 310 is configured to be connected to the first electrode terminal of the light-emitting subunit 210 to provide a first electrode signal.

[0055] For example, the number of first driving signal lines 310 included in each first driving signal line group 301 may be equal to the number of light-emitting sub-units 210 included in each light-emitting unit 201, so that the first driving signal lines 310 may be used to provide corresponding first electrode signals to different light-emitting sub-units 210 in each light-emitting unit 201. Figure 1 Taking the illustrated situation as an example, each light-emitting unit 201 may include three light-emitting sub-units 210, and each first driving signal line group 301 may correspondingly include three first driving signal lines 310. It should be noted that: Figure 1 The number of light-emitting sub-units 210 included in each light-emitting unit 201 and the number of first driving signal lines 310 included in each first driving signal line group 301 shown in the figure are merely exemplary descriptions and do not constitute limitations to the present disclosure.

[0056] For example, in the light-emitting substrate 10 provided in the embodiment of the present disclosure, the first electrode terminal of the light-emitting subunit 210 may be an anode terminal, or may be a cathode terminal, and accordingly, the first electrode signal provided to the first electrode terminal of the light-emitting subunit 210 may be an anode signal or a cathode signal for driving the light-emitting subunit 210 to emit light. Thus, by connecting the first drive signal line 310 to the first electrode terminal of the light-emitting subunit 210, the corresponding anode signal or cathode signal may be provided to the corresponding electrode terminal of the light-emitting subunit 210 to drive the light-emitting subunit 210 to emit light. For example, in the case where the first electrode terminal of the light-emitting sub-unit 210 is the anode terminal and the second electrode terminal is the cathode terminal, the first drive signal line 310 can be configured to be connected to the anode terminal (that is, the first electrode terminal) of the light-emitting sub-unit 210 and provide an anode signal as the first electrode signal; or, in the case where the first electrode terminal of the light-emitting sub-unit 210 is the cathode terminal and the second electrode terminal is the anode terminal, the first drive signal line 310 can be configured to be connected to the cathode terminal (that is, the first electrode terminal) of the light-emitting sub-unit 210 and provide a cathode signal as the first electrode signal, and the embodiments of the present disclosure are not limited to this.

[0057] like Figure 1As shown, the plurality of light emitting units 201 are arranged in a plurality of columns and a plurality of rows along a row direction R1 (eg, a first direction R1 ) and a column direction R2 (eg, a second direction R2 ), respectively.

[0058] In the Nth column of light emitting units and the N+1th column of light emitting units (for example Figure 3 , the k-th light emitting unit 201 in the N-th column of light emitting units and the k-th light emitting unit 201 in the N+1-th column of light emitting units have a translational spacing relative to each other in the column direction R2 (e.g. Figure 2 ), and the translation spacing is smaller than the spacing between two adjacent light-emitting units 201 in the same column in the column direction R2, so that each light-emitting unit 201 in the Nth column of light-emitting units and the N+1th column of light-emitting units is respectively and sequentially located in different rows, and N and k are both positive integers greater than 0. For example, the kth light-emitting unit 201 in the N+1th column of light-emitting units may be located between the kth light-emitting unit 201 in the Nth column of light-emitting units and the k+1th light-emitting unit 201 in the Nth column of light-emitting units in the column direction R2, or the kth light-emitting unit 201 in the Nth column of light-emitting units may be located between the kth light-emitting unit 201 in the N+1th column of light-emitting units and the k+1th light-emitting unit 201 in the N+1th column of light-emitting units in the column direction R2, thereby making each light-emitting unit 201 in two adjacent columns of light-emitting units staggered in the column direction R2, and further making each light-emitting unit 201 in the two adjacent columns of light-emitting units respectively and sequentially located in different rows along the column direction R2.

[0059] For example, Figure 3 As shown in FIG, the first column of light-emitting units 2011 and the second column of light-emitting units 2012 are respectively the Nth column of light-emitting units and the N+1th column of light-emitting units. The light-emitting units 201 in the first column of light-emitting units 2011 and the second column of light-emitting units 2012 are arranged in a staggered manner relative to a reference line L1 extending along the column direction R2. For example, the light-emitting units 201 in the first column of light-emitting units 2011 and the second column of light-emitting units 2012 are alternately arranged on both sides of the reference line L1 along the column direction R2. Figure 3Taking the light-emitting unit 2101 shown in the figure as the k-th light-emitting unit 201 in the first column of light-emitting units 2011, and the light-emitting unit 2102 as the k-th light-emitting unit 201 in the second column of light-emitting units 2012 as an example, the light-emitting unit 2101 and the light-emitting unit 2102 have a relative translation spacing in the column direction R2, and the translation spacing is smaller than the spacing between two adjacent light-emitting units 201 in the same column (for example, the light-emitting unit 2101 and the light-emitting unit 2103 in the first column of light-emitting units 2011) in the column direction R2, so that the light-emitting unit 2101, the light-emitting unit 2102 and the light-emitting unit 2103 are respectively located in different rows, thereby each light-emitting unit 201 in the first column of light-emitting units 2011 and the second column of light-emitting units 2012 are respectively located in different rows in sequence.

[0060] For example, when the light emitting units 201 in two adjacent columns of light emitting units are arranged alternately in the column direction R2, the light emitting units in two adjacent rows (eg Figure 3 The light emitting units 201 in the first row of light emitting units 2021 and the second row of light emitting units 2022, or the second row of light emitting units 2022 and the third row of light emitting units 2023) are also arranged in a staggered manner in the row direction R1. Figure 3 Taking the first row of light-emitting cells 2021 and the second row of light-emitting cells 2022 shown in the figure as examples, the light-emitting cells 201 in the first row of light-emitting cells 2021 and the second row of light-emitting cells 2022 are arranged in a staggered manner relative to a reference line L2 extending along the row direction R1. For example, the light-emitting cells 201 in the first row of light-emitting cells 2021 and the second row of light-emitting cells 2022 are alternately arranged on both sides of the reference line L2 along the row direction R1, so that the light-emitting cells 201 in the first row of light-emitting cells 2021 and the second row of light-emitting cells 2022 are respectively located in different columns in sequence.

[0061] It should be noted that Figure 1 Only some rows and some columns of light-emitting units 201 included in the light-emitting substrate 10 are shown in the figure. The embodiment of the present disclosure does not limit the specific number, number of rows, number of columns, etc. of the light-emitting units 201 included in the light-emitting substrate 10. For example, in the light-emitting substrate provided in the embodiment of the present disclosure, the number of rows of light-emitting units can be less than or more than Figure 1 The number of rows shown in FIG. 1 and the number of columns of the light-emitting unit may be less than or more than Figure 1 The number of columns shown in .

[0062] For example, the first driving signal line group 301 is located between the Nth column light-emitting unit and the N+1th column light-emitting unit, and extends in a zigzag manner along the column direction R2 and alternately passes through the Mth row and Nth column light-emitting unit 201, the M+1th row and N+1th column light-emitting unit 201, and the M+2th row and Nth column light-emitting unit 201 to provide a first electrode signal to each light-emitting unit 201 in the Nth column light-emitting unit and the N+1th column light-emitting unit, where M is a positive integer greater than 0.

[0063] For example, Figure 3 As shown in FIG. 1 , the first column of light emitting units 2011 and the second column of light emitting units 2012 are respectively the Nth column of light emitting units and the N+1th column of light emitting units. Figure 1 and Figure 3 As shown, the first driving signal line group 301 is located between the first column of light-emitting units 2011 and the second column of light-emitting units 2012 adjacent to each other in the row direction R1, and extends in a zigzag manner along the column direction R2 and alternately passes through each light-emitting unit 201 in the first column of light-emitting units 2011 and the second column of light-emitting units 2012 to provide the first electrode signal to each light-emitting unit 201. For example, Figure 3 The light-emitting unit 2101 in the first column of light-emitting units 2011, the light-emitting unit 2102 in the second column of light-emitting units 2012, and the light-emitting unit 2103 in the first column of light-emitting units 2011 shown in the figure can respectively correspond to the light-emitting unit 201 in the Mth row and Nth column, the light-emitting unit 201 in the M+1th row and N+1th column, and the light-emitting unit 201 in the M+2th row and Nth column. The first driving signal line group 301 located between the first column of light-emitting units 2011 and the second column of light-emitting units 2012 extends in a zigzag manner along the column direction R2 and alternately passes through the light-emitting units 2101, the light-emitting units 2102 and the light-emitting units 2103 located in different rows, thereby providing the first electrode signal to each light-emitting unit 201 in the first column of light-emitting units 2011 and the second column of light-emitting units 2012.

[0064] For example, Figure 1 As shown, each light-emitting unit 201 has two adjacent first drive signal line groups 301 passing through. It should be noted that "passing through" in the embodiment of the present disclosure includes the situation that the first drive signal line 310 in the first drive signal line group 301 at least partially overlaps with the light-emitting unit 201 in the direction perpendicular to the base substrate 101, and may also include the situation that the first drive signal line 310 in the first drive signal line group 301 extends to the vicinity of the light-emitting sub-unit 210 so as to facilitate the connection between the first drive signal line 310 and the corresponding light-emitting sub-unit 210. From the overall point of view, the first drive signal line group 301 extends in a zigzag manner along the column direction R2; from a local point of view, the first drive signal line group 301 extends alternately toward the light-emitting units 201 in the two columns of light-emitting units to form the above-mentioned zigzag extension shape.

[0065] It should be noted that the first driving signal line group 301 here is only described as a driving signal line group located between two adjacent columns of light-emitting units, but does not exclude other forms of driving signal lines or driving signal line groups located at the edge of the light-emitting unit array. For example, corresponding to the outermost light-emitting unit column in the row direction R1, other forms of driving signal lines or driving signal line groups can also be set to provide the first electrode signal.

[0066] It should be noted that the first drive signal line group 301 extends in a zigzag manner along the column direction R2, which refers to the overall extension direction or overall extension shape of all the first drive signal lines 310 included in the first drive signal line group 301, that is, all the first drive signal lines 310 included in the first drive signal line group 301 extend in a zigzag manner along the column direction R2 as a whole. For example, the extension directions or extension shapes of the first drive signal lines 310 included in the first drive signal line group 301 may be the same as or different from each other.

[0067] For example, each light-emitting subunit 210 in each light-emitting unit 201 can obtain the required first electrode signal through the first drive signal line 310 in two adjacent first drive signal line groups 301. For example, the first electrode signals required by the multiple light-emitting subunits 210 in each light-emitting unit 201 can be provided by one of the first drive signal line groups 301 passing through the two adjacent first drive signal line groups 301 of the light-emitting unit 201, that is, provided by each first drive signal line 310 in one of the first drive signal line groups 301; or, the multiple light-emitting subunits 210 in the light-emitting unit 201 can be respectively connected to the first drive signal lines 310 in different first drive signal line groups 301 to obtain the required first electrode signal.

[0068] Therefore, in the light-emitting substrate 10 provided by the embodiment of the present disclosure, while providing the first electrode signal to each light-emitting sub-unit 210 in the light-emitting unit 201 through the first drive signal line 310 in the first drive signal line group 301, the first drive signal line group 301 is extended in a zigzag manner along the column direction R2 between two adjacent columns of light-emitting units, and the plurality of first drive signal line groups 301 are used to form a uniform wiring structure in a plane parallel to the main surface of the base substrate 101 in a form similar to a grid, so that each first drive signal line 310 in the first drive signal line group 301 can form a selection of passing and blocking the light passing through the base substrate 101, thereby improving the uniformity of the selection of the light passing through the base substrate 101, thereby improving the uniformity of the emitted light of the light-emitting substrate 10, and improving the light uniformity of the entire light-emitting substrate 10.

[0069] For example, in Figure 1In the illustrated embodiment, each first drive signal line 310 in the first drive signal line group 301 can extend in a zigzag manner along the column direction R2, so that the first drive signal lines 310 in the first drive signal line group 301 are arranged relatively evenly on the substrate 101, further improving the uniformity of the grid routing structure formed by the first drive signal line group 301.

[0070] For example, in Figure 1 In the illustrated embodiment, the width occupied by each first drive signal line group 301 in the row direction R1 can be substantially the same, and the overall shape of the meandering extension along the column direction R2 can remain substantially consistent with each other, thereby improving the uniformity of the grid-like routing structure formed by the multiple first drive signal line groups 301 on the base substrate 101, further improving the uniformity of the selection of light passing through the base substrate 101, and thereby improving the uniformity of the output light of the light-emitting substrate 10.

[0071] For example, in Figure 1 In the illustrated embodiment, the number of first drive signal lines 310 included in each first drive signal line group 301, as well as the extension direction, extension shape, width occupied in the row direction R1, etc. of each first drive signal line 310 can be substantially the same as one another, thereby further improving the uniformity of the grid-like routing structure formed by the multiple first drive signal line groups 301 on the substrate 101.

[0072] It should be noted that, in some other embodiments of the present disclosure, the width occupied by each first drive signal line group 301 in the row direction R1, the extension shape along the column direction R2, and the number, size, arrangement, etc. of the first drive signal lines 310 included in each first drive signal line group 301 may also be different from each other, and the embodiments of the present disclosure are not limited to this.

[0073] It should be noted that, in the embodiment of the present disclosure, the first driving signal line group 301 extends in a zigzag manner along the column direction R2, which means that the overall extension direction or overall extension shape of the first driving signal line group 301 in the column direction R2 extends in a zigzag manner. For example, the extension direction or extension shape of different parts of the first driving signal line group 301 (for example, between two adjacent columns of light-emitting units in the row direction R1, and the part of the first driving signal line group 301 located between two adjacent rows of light-emitting units in the column direction R2) can be as follows: Figure 1 It may extend in a straight line as shown in the figure, or in some other embodiments of the present disclosure, it may extend in a broken line, a curve or other suitable shapes, and the embodiments of the present disclosure are not limited to this.

[0074] In some embodiments of the present disclosure, Figure 1As shown, between two adjacent columns of light-emitting units in the row direction R1, the first drive signal line group 301 extends approximately along a straight line between two light-emitting units 201 located in two adjacent rows, that is, between two adjacent columns of light-emitting units in the row direction R1, the first drive signal line group 301 extends approximately along a straight line between any two light-emitting units 201 located in different columns and adjacent in the column direction R2. Figure 3 As shown in the figure, two light-emitting units 2101 and 2102 are respectively located in the first column of light-emitting units 2011 and the second column of light-emitting units 2012 adjacent in the row direction R1 and adjacent in the column direction R2 (i.e., located in two adjacent rows), between the light-emitting units 2101 and 2102, the first drive signal line group 301 extends approximately along a straight line, for example, each first drive signal line 310 in the first drive signal line group 301 extends approximately along a straight line. Thus, it can not only help to improve the uniformity of the arrangement of the first drive signal line group 301 and the first drive signal lines 310 in the first drive signal line group 301 on the base substrate 101, optimize the arrangement mode, thereby facilitating the formation of a uniform grid-like routing structure in a plane parallel to the main surface of the base substrate 101, but also reduce the preparation cost of the first drive signal line 310 and improve the preparation process.

[0075] It should be noted that, in some other embodiments of the present disclosure, taking the light-emitting units 2101 and 2102 as an example, between the light-emitting units 2101 and 2102, the first drive signal line group 301 (for example, each first drive signal line 310 in the first drive signal line group 301) may also extend in a zigzag shape, a curve shape or other suitable shapes, and the embodiments of the present disclosure are not limited to this.

[0076] In some embodiments of the present disclosure, for example, taking the light emitting units 2101, 2102 and 2103 as an example, in combination with Figure 1 and Figure 3As shown, the relative translation spacing between the light-emitting units 2101 and 2102 (or the light-emitting units 2102 and 2103) in the column direction R2 is equal to 1 / 2 of the spacing between two adjacent light-emitting units 201 (for example, the light-emitting units 2101 and 2103) in the same column in the column direction R2. Between the first column of light-emitting units 2011 and the second column of light-emitting units 2012, the angle α1 of the extension direction of the first drive signal line group 301 between the light-emitting units 2101 and 2102 relative to the row direction R1 is equal to the angle α2 of the extension direction of the first drive signal line group 301 between the light-emitting units 2102 and 2103 relative to the row direction R1. Thus, the arrangement uniformity of the first drive signal line group 301 and the first drive signal line 310 in the first drive signal line group 301 on the substrate 101 can be further improved, and the arrangement method can be optimized, so as to facilitate the formation of a uniform grid-like routing structure in a plane parallel to the main surface of the substrate 101.

[0077] Figure 2 A schematic diagram of an arrangement of light-emitting units in a light-emitting substrate provided in some embodiments of the present disclosure.

[0078] In some embodiments of the present disclosure, Figure 1 and Figure 2 As shown, in the multiple columns of light-emitting units arranged along the row direction R1, the spacing D1 between two adjacent columns of light-emitting units in the row direction R1 is greater than 0, for example, the spacing D1 between the orthographic projections of the two adjacent columns of light-emitting units on the substrate 101 in the row direction R1 is greater than 0. In the multiple rows of light-emitting units arranged along the column direction R2, the spacing D2 between two adjacent rows of light-emitting units in the column direction R2 is greater than 0, for example, the spacing D2 between the orthographic projections of the two adjacent rows of light-emitting units on the substrate 101 in the column direction R2 is greater than 0. That is, in two adjacent columns of light-emitting units in the row direction R1, the spacing between any two light-emitting units 201 located in different columns and adjacent in the column direction R2 in the row direction R1 is greater than 0, or it can also be understood that the spacing between the orthographic projections of the above two light-emitting units 201 on the substrate 101 in the row direction R1 is greater than 0; in two adjacent rows of light-emitting units in the column direction R2, the spacing between any two light-emitting units 201 located in different rows and adjacent in the row direction R1 in the column direction R2 is greater than 0, or it can also be understood that the spacing between the orthographic projections of the above two light-emitting units 201 on the substrate 101 in the column direction R2 is greater than 0. In this way, it is possible to reduce or avoid the mutual interference or influence of the light emitted by different light-emitting units 201, thereby optimizing the light-emitting effect of the light-emitting substrate 10, and it is also possible to facilitate the arrangement of the first drive signal line group 301 between two adjacent columns of light-emitting units.

[0079] In some embodiments of the present disclosure, Figure 1 and Figure 2 As shown, in the multiple columns of light-emitting units arranged along the row direction R1, the spacing D1 between two adjacent columns of light-emitting units in the row direction R1 is equal to each other, that is, in the multiple columns of light-emitting units arranged along the row direction R1, the spacing D1 between the orthographic projections of two adjacent columns of light-emitting units on the substrate 101 in the row direction R1 is equal to each other; in the multiple rows of light-emitting units arranged along the column direction R2, the spacing D2 between two adjacent rows of light-emitting units in the column direction R2 is equal to each other, that is, in the multiple rows of light-emitting units arranged along the column direction R2, the spacing D2 between the orthographic projections of two adjacent rows of light-emitting units on the substrate 101 in the column direction R2 is equal to each other. In other words, in two adjacent columns of light-emitting units in the row direction R1, the spacing D1 in the row direction R1 between the orthographic projections of any two light-emitting units 201 that are respectively located in different columns and adjacent in the column direction R2 on the substrate 101 are equal to each other; in two adjacent rows of light-emitting units in the column direction R2, the spacing D2 in the column direction R2 between the orthographic projections of any two light-emitting units 201 that are respectively located in different rows and adjacent in the row direction R1 on the substrate 101 are equal to each other.

[0080] Thus, it is possible to Figure 2 The four adjacent light-emitting units 201 in the dashed frame shown in the figure approximately form a diamond structure in a plane parallel to the main surface of the base substrate 101, thereby optimizing the arrangement of the multiple light-emitting units 201 in the light-emitting substrate 10 and further improving the uniformity of the emitted light of the light-emitting substrate 10. Figure 1 and Figure 2 As shown, when multiple light-emitting units 201 adopt the above-mentioned arrangement method, multiple first drive signal line groups 301 that extend in a zigzag manner along the column direction R2 can form a uniform grid-like routing structure composed of multiple grids that are approximately rhombus-shaped in a plane parallel to the main surface of the base substrate 101, thereby further improving the arrangement uniformity of the multiple first drive signal line groups 301 on the base substrate 101, and then further improving the uniformity of the selection of light passing through the base substrate 101 through the first drive signal lines 310 in the multiple first drive signal line groups 301, thereby improving the uniformity of the emitted light of the light-emitting substrate 10 and improving the light emission uniformity of the entire light-emitting substrate 10.

[0081] In some embodiments of the present disclosure, among the plurality of light-emitting units 201 arranged in multiple rows and columns, the spacing D1 between the orthographic projections of two adjacent columns of light-emitting units on the substrate 101 in the row direction R1 may be further equal to the spacing D2 between the orthographic projections of two adjacent rows of light-emitting units on the substrate 101 in the column direction R2. For example, among the plurality of light-emitting units 201, the distances between the centers of the orthographic projections of two adjacent light-emitting units 201 located in different rows and columns on the substrate 101 are equal to each other. Thus, the light-emitting units 201 adjacent to each other and located in different rows or columns can approximately form an equilateral triangle structure, for example, Figure 2 Two equilateral triangle structures are formed between the four adjacent light-emitting units 201 in the dashed frame, thereby further optimizing the arrangement of the multiple light-emitting units 201 in the light-emitting substrate 10 and improving the uniformity of the emitted light of the light-emitting substrate 10 .

[0082] In some embodiments of the present disclosure, between two adjacent columns of light-emitting units in the row direction R1, the first drive signal line group 301 overlaps at least partially with each light-emitting unit 201 in the two adjacent columns of light-emitting units in a direction perpendicular to the base substrate 101, so as to alternately pass through each light-emitting unit 201 in the two adjacent columns of light-emitting units. Thus, the first drive signal line 310 in the first drive signal line group 301 can realize electrical connection with the corresponding light-emitting sub-unit 210 in the light-emitting unit 201 in the overlapping portion, thereby reducing the space required to be occupied by the conductive components or structures used to realize the above electrical connection in the plane parallel to the main surface of the base substrate 101, and optimizing the layout design of the first drive signal line group 301 in the light-emitting substrate 10. For example, in the light-emitting substrate 10 provided in the embodiment of the present disclosure, an insulating layer or other interlayer structure may be provided between the light-emitting sub-unit 210 in the light-emitting unit 201 and the corresponding first drive signal line 310 in the first drive signal line group 301, and the electrical connection is realized in the overlapping portion by a via design penetrating the insulating layer or other interlayer structure.

[0083] It should be noted that in Figure 1 In the light-emitting substrate 10 shown in FIG. 1 , the light-emitting unit 201 is Figure 1 301 in the first driving signal line group 301, but this does not constitute a limitation on the embodiments of the present disclosure. For example, in some embodiments of the present disclosure, the first driving signal line group 301 may be located on the side of the light emitting unit 201 close to the base substrate 101; or, in some other embodiments of the present disclosure, the first driving signal line group 301 may also be located on the side of the light emitting unit 201 away from the base substrate 101, and the embodiments of the present disclosure are not limited to this.

[0084] It should be noted that, in some other embodiments of the present disclosure, the light-emitting unit 201 and the first drive signal line 310 in the first drive signal line group 301 may also be arranged in other suitable manners in a direction perpendicular to the base substrate 101. For example, one or more first drive signal lines 310 in the first drive signal line group 301 may also be arranged in the same layer as the light-emitting unit 201, and the embodiments of the present disclosure are not limited to this.

[0085] In some embodiments of the present disclosure, each first drive signal line 310 in the first drive signal line group 301 is connected to the first electrode end of a light-emitting sub-unit 210 in the light-emitting unit 201 through which the first drive signal line group 301 passes, so that each first drive signal line 310 in the first drive signal line group 301 provides a first electrode signal to the corresponding light-emitting sub-unit 210.

[0086] Figure 3 A partial plan view of a light-emitting substrate provided in some embodiments of the present disclosure. Figure 3 Taking the first column of light-emitting units 2011, the second column of light-emitting units 2012 and the third column of light-emitting units 2013 as examples, the Nth column of light-emitting units, the N+1th column of light-emitting units and the N+2th column of light-emitting units are respectively shown, in combination with the first signal line group 3011 (also known as the first drive signal line group 301) located between the first column of light-emitting units 2011 and the second column of light-emitting units 2012 included in the plurality of first drive signal line groups 301 and the second signal line group 3012 (also known as the first drive signal line group 301) located between the second column of light-emitting units 2012 and the third column of light-emitting units 2013, the specific connection method between the first drive signal line 310 and the light-emitting sub-unit 210 is described.

[0087] Figure 4 for Figure 3 It should be noted that in some examples, the second driving signal line group 302 can be as follows: Figure 4 As shown in FIG. 3 , the second driving signal line group 302 includes a first conductive portion 325 and a second conductive portion 326; or, in some other examples, the second driving signal line group 302 may not include Figure 4 The first conductive portion 325 and the second conductive portion 326 are shown in FIG. , but the embodiments of the present disclosure are not limited thereto.

[0088] For example, combined with Figures 1 to 4As shown, the plurality of light-emitting units 201 include a first column of light-emitting units 2011 and a second column of light-emitting units 2012 adjacent in the row direction R1, and a second column of light-emitting units 2012 and a third column of light-emitting units 2013 adjacent in the row direction R1. For example, the first column of light-emitting units 2011, the second column of light-emitting units 2012, and the third column of light-emitting units 2013 are sequentially arranged adjacent to each other in the row direction R1. The plurality of first drive signal line groups 301 include a first signal line group 3011 (also known as a first drive signal line group 301) located between the first column of light-emitting units 2011 and the second column of light-emitting units 2012 adjacent in the row direction R1, and a second signal line group 3012 (also known as a first drive signal line group 301) located between the second column of light-emitting units 2012 and the third column of light-emitting units 2013 adjacent in the row direction R1.

[0089] It should be noted that, in the embodiments of the present disclosure, "arranged in sequence" may mean that they are arranged in sequence from left to right or from right to left in the row direction R1 and are adjacent to each other in the row direction R1, or it may mean that they are arranged in sequence from top to bottom or from bottom to top in the column direction R2 and are adjacent to each other in the column direction R2.

[0090] For example, the plurality of light-emitting subunits 210 in each light-emitting unit 201 include a first light-emitting subunit 211 and a second light-emitting subunit 212. The first light-emitting subunit 211 and the second light-emitting subunit 212 are arranged adjacent to each other in the row direction R1. For example, the first light-emitting subunit 211 can be as follows: Figure 4 As shown, the arrangement is on the right side of the second light-emitting subunit 212. The first driving signal line 310 in each first driving signal line group 301 includes a first light-emitting signal line 311 (i.e., the first driving signal line 310) corresponding to the first light-emitting subunit 211 and a second light-emitting signal line 312 (i.e., the first driving signal line 310) corresponding to the second light-emitting subunit 212, the first light-emitting signal line 311 is configured to be connected to the first electrode end of the first light-emitting subunit 211 to provide a first electrode signal corresponding to the first light-emitting subunit 211, and the second light-emitting signal line 312 is configured to be connected to the first electrode end of the second light-emitting subunit 212 to provide a first electrode signal corresponding to the second light-emitting subunit 212.

[0091] It should be noted that, in the embodiments of the present disclosure, "adjacent arrangement" may refer to being arranged adjacent to each other in the order from left to right or from right to left in the row direction R1, or may refer to being arranged adjacent to each other in the order from top to bottom or from bottom to top in the column direction R2.

[0092] For example, taking the first signal line group 3011 located between the first column of light emitting units 2011 and the second column of light emitting units 2012 adjacent to each other in the row direction R1 as an example, Figure 3and Figure 4 As shown, the first light-emitting signal line 311 in the first signal line group 3011 is connected to the first light-emitting sub-unit 211 in each light-emitting unit 201 of the first column of light-emitting units 2011, and the second light-emitting signal line 312 is connected to the second light-emitting sub-unit 212 in each light-emitting unit 201 of the second column of light-emitting units 2012.

[0093] For example, taking the second signal line group 3012 located between the second column of light emitting units 2012 and the third column of light emitting units 2013 adjacent to each other in the row direction R1 as an example, Figure 3 and Figure 4 As shown, the first light-emitting signal line 311 in the second signal line group 3012 is connected to the first light-emitting sub-unit 211 in each light-emitting unit 201 of the second column light-emitting unit 2012, and the second light-emitting signal line 312 in the second signal line group 3012 is connected to the second light-emitting sub-unit 212 in each light-emitting unit 201 of the third column light-emitting unit 2013.

[0094] Thus, each light-emitting unit 201 in each column of light-emitting units can obtain the required first electrode signal by passing through two adjacent first driving signal line groups 301 of the light-emitting unit 201. For example, taking the second column of light-emitting units 2012 as an example, the first light-emitting unit 211 in the second column of light-emitting units 2012 can obtain the required first electrode signal through the first light-emitting signal line 311 in the second signal line group 3012, and the second light-emitting unit 212 in the second column of light-emitting units 2012 can obtain the required first electrode signal through the second light-emitting signal line 312 in the first signal line group 3011.

[0095] For example, Figure 4 As shown, in each first driving signal line group 301, the first light-emitting signal line 311 and the second light-emitting signal line 312 are sequentially arranged along the row direction R1 from the second light-emitting subunit 212 in each light-emitting unit 201 to the first light-emitting subunit 211, for example, Figure 4 Taking the arrangement sequence of the first light-emitting subunit 211 and the second light-emitting subunit 212 shown in FIG as an example, the first light-emitting signal line 311 and the second light-emitting signal line 312 are arranged in sequence from left to right along the row direction R1.

[0096] It should be noted that, in the embodiments of the present disclosure, "arranged in sequence" may mean arranged in sequence from left to right or from right to left in the row direction R1, or may mean arranged in sequence from top to bottom or from bottom to top in the column direction R2.

[0097] For example, the plurality of light-emitting subunits 210 in each light-emitting unit 201 further include a third light-emitting subunit 213, and the third light-emitting subunit 213 is arranged in parallel with the first light-emitting subunit 211 and the second light-emitting subunit 212 in the column direction R2. Figure 4 As shown, the first light-emitting subunit 211, the second light-emitting subunit 212 and the third light-emitting subunit 213 are arranged in two rows respectively, the first light-emitting subunit 211 and the second light-emitting subunit 212 are located in the same row, and the third light-emitting subunit 213 is located above the first light-emitting subunit 211 and the second light-emitting subunit 212. The first driving signal line 310 in each first driving signal line group 301 also includes a third light-emitting signal line 313 corresponding to the third light-emitting subunit 213, and the third light-emitting signal line 313 is configured to be connected to the first electrode end of the third light-emitting subunit 213 to provide a first electrode signal corresponding to the third light-emitting subunit 213.

[0098] It should be noted that, in the embodiments of the present disclosure, "arranged in parallel" may refer to being arranged in sequence from left to right or from right to left in the row direction R1. For example, when two are arranged in parallel in the row direction R1, one of them may be located on the left or right side of the other; or, "arranged in parallel" may refer to being arranged in sequence from top to bottom or from bottom to top in the column direction R2. For example, when two are arranged in parallel in the column direction R2, one of them may be located above or below the other.

[0099] For example, taking the first signal line group 3011 located between the first column of light-emitting units 2011 and the second column of light-emitting units 2012 adjacent to each other in the row direction R1 and the second signal line group 3012 located between the second column of light-emitting units 2012 and the third column of light-emitting units 2013 adjacent to each other in the row direction R1 as examples, the third light-emitting signal line 313 in the first signal line group 3011 is connected to the third light-emitting sub-unit 213 in each light-emitting unit 201 of the second column of light-emitting units 2012, and the third light-emitting signal line 313 in the second signal line group 3012 is connected to the third light-emitting sub-unit 213 in each light-emitting unit 201 of the third column of light-emitting units 2013.

[0100] Thus, each light-emitting unit 201 in each column of light-emitting units can obtain the required first electrode signal by passing through two adjacent first driving signal line groups 301 of the light-emitting unit 201. For example, taking the second column of light-emitting units 2012 as an example, the first light-emitting unit 211 in the second column of light-emitting units 2012 can obtain the required first electrode signal through the first light-emitting signal line 311 in the second signal line group 3012, the second light-emitting unit 212 in the second column of light-emitting units 2012 can obtain the required first electrode signal through the second light-emitting signal line 312 in the first signal line group 3011, and the third light-emitting unit 213 in the second column of light-emitting units 2012 can obtain the required first electrode signal through the third light-emitting signal line 313 in the first signal line group 3011.

[0101] For example, in some other embodiments of the present disclosure, the third light-emitting signal line 313 in the first signal line group 3011 may be connected to the third light-emitting sub-unit 213 in each light-emitting unit 201 of the first column of light-emitting units 2011, and the third light-emitting signal line 313 in the second signal line group 3012 may be connected to the third light-emitting sub-unit 213 in each light-emitting unit 201 of the second column of light-emitting units 2012.

[0102] In other words, Figure 3 and Figure 4 Taking the light-emitting unit 201 shown in the figure as an example, for each light-emitting sub-unit 210 in the light-emitting unit 201, that is, the first light-emitting sub-unit 211, the second light-emitting sub-unit 212 and the third light-emitting sub-unit 213, in the two groups of first driving signal line groups 301 passing through the light-emitting unit 201, the third light-emitting signal line 313 corresponding to the third light-emitting sub-unit 213 and the first light-emitting signal line 311 corresponding to the first light-emitting sub-unit 211 may belong to one of the first driving signal line groups 301, and the second light-emitting signal line 312 corresponding to the second light-emitting sub-unit 212 may belong to another first driving signal line group 301; or, the third light-emitting signal line 313 corresponding to the third light-emitting sub-unit 213 and the second light-emitting signal line 312 corresponding to the second light-emitting sub-unit 212 may belong to one of the first driving signal line groups 301, and the first light-emitting signal line 311 corresponding to the first light-emitting sub-unit 211 may belong to another first driving signal line group 301, and the embodiments of the present disclosure are not limited to this.

[0103] For example, the second light-emitting subunit 212, the third light-emitting subunit 213 and the first light-emitting subunit 211 are arranged in sequence in the row direction R1, for example, Figure 4 As shown, the center of the second light-emitting subunit 212, the center of the third light-emitting subunit 213 and the center of the first light-emitting subunit 211 are arranged in sequence from left to right in the row direction R1. Figure 4In the first signal line group 3011 and the second signal line group 3012 shown in FIG, the first light-emitting signal line 311, the second light-emitting signal line 312 and the third light-emitting signal line 313 are sequentially arranged in a row direction R1 from the second light-emitting subunit 212 in each light-emitting unit 201 to the first light-emitting subunit 211, for example, Figure 4 As shown, the first light emitting signal line 311 , the second light emitting signal line 312 and the third light emitting signal line 313 are sequentially arranged from left to right along the row direction R1 .

[0104] It should be noted that, in the embodiments of the present disclosure, "arranged in sequence" may refer to being arranged in sequence from left to right or from right to left in the row direction R1, or may refer to being arranged in sequence from top to bottom or from bottom to top in the column direction R2.

[0105] It should be noted that in some other embodiments of the present disclosure, each light-emitting unit 201 may also include fewer or more light-emitting sub-units 210, and the light-emitting sub-units 210 in each light-emitting unit 201 may also adopt other suitable arrangements accordingly, and the embodiments of the present disclosure are not limited to this.

[0106] It should be noted that, in the embodiments of the present disclosure, the connection method between the first drive signal line 310 in the first drive signal line group 301 located between two adjacent columns of light-emitting units and each light-emitting sub-unit 210 in the two adjacent columns of light-emitting units and the arrangement order in the row direction R1 are merely exemplary descriptions, and the embodiments of the present disclosure are not limited thereto.

[0107] In some embodiments of the present disclosure, the first light-emitting subunit 211, the second light-emitting subunit 212, and the third light-emitting subunit 213 can be configured to provide light of different colors, respectively. For example, the first light-emitting subunit 211, the second light-emitting subunit 212, and the third light-emitting subunit 213 can be configured to provide blue, green, and red light, respectively; or, in some embodiments of the present disclosure, the first light-emitting subunit 211, the second light-emitting subunit 212, and the third light-emitting subunit 213 can also be configured to provide other different colors of light, respectively, and the embodiments of the present disclosure are not limited to this. Alternatively, in some embodiments of the present disclosure, the first light-emitting subunit 211, the second light-emitting subunit 212, and the third light-emitting subunit 213 can also be configured to provide light of the same color. For example, in this case, the light-emitting substrate 10 can include a color filter structure such as a color film layer to provide light of different colors. The embodiments of the present disclosure do not limit the specific color of the light provided by each light-emitting subunit 210 in the light-emitting unit 201.

[0108] For example, the width of the first driving signal line 310 in the first driving signal line group 301 in the row direction R1 may be 40 μm to 60 μm, that is, the width of the first light-emitting signal line 311, the second light-emitting signal line 312 and the third light-emitting signal line 313 in the first driving signal line group 301 in the row direction R1 may be 40 μm to 60 μm, and further, for example, 40 μm, 45 μm, 50 μm, 55 μm, 60 μm, etc. In each first driving signal line group 301, the spacing between the first light-emitting signal line 311 and the second light-emitting signal line 312 or between the third light-emitting signal line 313 and the second light-emitting signal line 312 in the row direction R1 may be, for example, 10 μm to 30 μm, and further, for example, 10 μm, 15 μm, 20 μm, 25 μm, 30 μm, etc.

[0109] For example, Figure 4 As shown, the first light-emitting signal line 311, the second light-emitting signal line 312 and the third light-emitting signal line 313 can be arranged around and close to the first light-emitting subunit 211, the second light-emitting subunit 212 and the third light-emitting subunit 213 as much as possible, so that the first light-emitting signal line 311, the second light-emitting signal line 312 and the third light-emitting signal line 313 can be used to better block the light at the position close to the first light-emitting subunit 211, the second light-emitting subunit 212 and the third light-emitting subunit 213, thereby improving the uniformity of the light selection in the entire light-emitting substrate 10, and thus improving the uniformity of the light emitted from the light-emitting substrate 10. For example, Figure 4 As shown, the bending angle between the first light-emitting signal line 311, the second light-emitting signal line 312 and the third light-emitting signal line 313 and the row direction R1 can be about 60°, thereby reducing the area of ​​irregular routing that may be generated and reducing or avoiding the adverse effect on the uniformity of the grid routing structure formed by multiple first drive signal line groups 301.

[0110] For example, in some embodiments of the present disclosure, Figures 1 to 5 As shown, the light-emitting substrate 10 further includes a plurality of second drive signal line groups 302. The plurality of second drive signal line groups 302 extend along the row direction R1 and correspond to the plurality of rows of light-emitting units one by one, and each second drive signal line group 302 includes at least one second drive signal line 320, and the second drive signal line 320 is configured to be connected to the second electrode end of the light-emitting sub-unit 210 to provide a second electrode signal.

[0111] For example, the first electrode signal and the second electrode signal may be respectively an anode signal and a cathode signal for driving the light-emitting subunit 210 to emit light. For example, the first electrode signal provided by the first drive signal line 310 may be a cathode signal, and the second electrode signal provided by the second drive signal line 320 may be an anode signal; or, the first electrode signal provided by the first drive signal line 310 may be an anode signal, and the second electrode signal provided by the second drive signal line 320 may be a cathode signal, and the embodiments of the present disclosure are not limited to this.

[0112] For example, in Figure 1 In the illustrated embodiment, the number of second drive signal lines 320 included in each second drive signal line group 302 may be the same as the number of first drive signal lines 310 included in each first drive signal line group 301, that is, the same as the number of light-emitting sub-units 210 included in each light-emitting unit 201, thereby providing corresponding second electrode signals to different light-emitting sub-units 210 in each light-emitting unit 201 respectively through the second drive signal lines 320, and also enabling the first drive signal lines 310 in the first drive signal line group 301 and the second drive signal lines 320 in the second drive signal line group 302 to be arranged relatively evenly on the base substrate 101, and forming a uniform grid-like routing structure on the base substrate 101 by using the first drive signal line group 301 and the second drive signal line group 302. Furthermore, each first driving signal line 310 in the first driving signal line group 301 and each second driving signal line 320 in the second driving signal line group 302 can select to pass or block the light passing through the base substrate 101, thereby improving the uniformity of the light emitted from the light-emitting substrate 10 and improving the uniformity of the light emitted from the entire light-emitting substrate 10.

[0113] For example, a plurality of second driving signal line groups 302 extending along the row direction R1 may intersect with a plurality of first driving signal line groups 301 extending in a zigzag manner along the column direction R2 to form a plurality of triangular structures. Figure 1 In the case where the adjacent light-emitting units 201 in different rows or columns are arranged to form an equilateral triangle structure, the plurality of second drive signal line groups 302 and the plurality of first drive signal line groups 301 can cross each other and approximately form a plurality of equilateral triangle structures, thereby improving the uniformity of the grid-like routing structure formed by the first drive signal line 310 in the first drive signal line group 301 and the second drive signal line 320 in the second drive signal line group 302 on the substrate 101. For example, when the first drive signal line group 301 and the second drive signal line group 302 are arranged in the above manner, Figure 1The light uniformity of the light emitting substrate 10 shown can be improved to about 65.5%, thereby significantly improving the light uniformity of the light emitting substrate 10.

[0114] For example, in Figure 1 In the illustrated embodiment, the second drive signal line group 302 and the second drive signal line 320 therein may extend in a roughly straight line along the row direction R1; or, in some other embodiments of the present disclosure, the second drive signal line group 302 and the second drive signal line 320 therein may also extend in a zigzag line, a curve, or other suitable shapes along the row direction R1, and the embodiments of the present disclosure are not limited to this.

[0115] It should be noted that, in the embodiment of the present disclosure, different second drive signal line groups 302 or different second drive signal lines 320 in each second drive signal line group 302 may be the same as or different from each other. For example, the overall width of each second drive signal line group 302 in the column direction R2, the overall extension shape along the row direction R1, etc. may be the same as or different from each other; for example, the width of the second drive signal lines 320 in the second drive signal line group 302 in the column direction R2, the specific extension shape along the row direction R1, etc. may be the same as or different from each other, and the embodiment of the present disclosure does not limit this.

[0116] For example, in some embodiments of the present disclosure, each first drive signal line group 301 can be configured to be connected to different signal sources to receive corresponding first electrode signals, and each second drive signal line group 302 can be configured to be connected to different signal sources to receive corresponding second electrode signals, so that under the control of the first electrode signal provided by the first drive signal line 310 and the second electrode signal provided by the second drive signal line 320, each light-emitting unit 201 in the light-emitting substrate 10 can be used as an independent light-emitting area, thereby maximizing the partition control of multiple light-emitting units 201 in the light-emitting substrate 10. Furthermore, when the light-emitting substrate 10 is applied to, for example, a display product to provide light for display, the display product can achieve a higher level (for example, the highest level) of display contrast, thereby improving the picture display effect of the display product. Alternatively, in some other embodiments of the present disclosure, two adjacent first drive signal line groups 301 may be connected to the same signal source to share the same first electrode signal, or two adjacent second drive signal line groups 302 may be connected to the same signal source to share the same second electrode signal. When the light-emitting substrate 10 is applied to, for example, a display product to provide light for display, it is possible to ensure the picture display effect of the display product and optimize the display control method of the display product, thereby reducing the driving cost of the display product.

[0117] For example, the first driving signal line 310 and the second driving signal line 320 may be located in different layers of the light emitting substrate 10 . Figure 5 For along Figure 4 A schematic diagram of a partial cross-sectional structure of the AA' line shown in FIG. Figure 4 and Figure 5 As shown, the first driving signal line 310 (eg Figure 4 and Figure 5 The second light emitting signal line 312 and the third light emitting signal line 313 shown in FIG. 3 may be located on the second driving signal line 320 (eg Figure 4 and Figure 5 Alternatively, in some other embodiments of the present disclosure, the first drive signal line 310 may also be located on a side of the second drive signal line 320 close to the substrate 101, and the embodiments of the present disclosure are not limited to this.

[0118] For example, in the light-emitting substrate 10 provided in the embodiment of the present disclosure, the first electrode terminal of the light-emitting subunit 210 can be in direct contact with the first drive signal line 310 to achieve electrical connection, or an insulating layer or other interlayer structure can be provided between the first electrode terminal of the light-emitting subunit 210 and the first drive signal line 310, and the electrical connection is achieved by a via design that penetrates the insulating layer or other interlayer structure; the second electrode terminal of the light-emitting subunit 210 can be in direct contact with the second drive signal line 320 to achieve electrical connection, or an insulating layer or other interlayer structure can be provided between the second electrode terminal of the light-emitting subunit 210 and the second drive signal line 320, and the electrical connection is achieved by a via design that penetrates the insulating layer or other interlayer structure. The embodiment of the present disclosure does not specifically limit the specific connection method between the first electrode terminal of the light-emitting subunit 210 and the first drive signal line 310 and the specific connection method between the second electrode terminal of the light-emitting subunit 210 and the second drive signal line 320.

[0119] For example, Figure 5 Taking the example of the first driving signal line 310 being located on the side of the second driving signal line 320 away from the substrate 101, for example, insulating layers 1021 and 1022 or other interlayer structures may be provided between the second electrode end of the light-emitting subunit 210 and the second driving signal line 320, and the electrical connection is achieved by a via design penetrating the insulating layers 1021 and 1022 or other interlayer structures. Figure 4 and Figure 5As shown, the second electrode end of the light-emitting subunit 210 and the second driving signal line 320 can be electrically connected through a conductive connector 3211. For example, the conductive connector 3211 can be arranged in the same layer as the first driving signal line 310 and electrically connected to the second driving signal line 320 through a via hole penetrating the insulating layer 1021. It should be noted that in some other embodiments of the present disclosure, the light-emitting subunit 210 and the second driving signal line 320 can also adopt other suitable arrangements and connection methods in the direction perpendicular to the base substrate 101, and the embodiments of the present disclosure are not limited to this.

[0120] In some embodiments of the present disclosure, the light-emitting subunit 210 may be a light-emitting diode chip, such as a mini light-emitting diode chip (mini LED). For example, the maximum size of the mini light-emitting diode chip in a plane parallel to the main surface of the substrate 101 does not exceed 500 μm, for example, it may be 100 μm to 500 μm, and further for example, it may be 150 μm to 350 μm, etc. For example, the size of the mini light-emitting diode chip may be 0.2 mm×0.4 mm (width×length).

[0121] In some embodiments of the present disclosure, the light-emitting subunit 210 may also be a micro-LED chip. For example, the maximum size of the micro-LED chip in a plane parallel to the main surface of the base substrate 101 does not exceed 100 μm, for example, it may be 20 μm to 100 μm, and further for example, 30 μm to 80 μm.

[0122] In some embodiments of the present disclosure, the base substrate 101 may be a glass substrate, thereby reducing the preparation cost of the light-emitting substrate 10, and improving the heat dissipation performance of the base substrate 101, thereby improving the overall performance of the light-emitting substrate 10. In some embodiments of the present disclosure, the base substrate 101 may also be a substrate provided with a printed circuit board, thereby reducing the resistance thermal effect of the first drive signal line 310 and the second drive signal line 320 by, for example, reducing the width and increasing the thickness of the first drive signal line 310 and the second drive signal line 320. In addition, the parasitic capacitance that may be generated may be further reduced or avoided by adding an additional layer structure between the first drive signal line 310 and the second drive signal line 320. In some other embodiments of the present disclosure, the base substrate 101 may also be other suitable substrates, and the embodiments of the present disclosure are not limited to this.

[0123] For example, the first drive signal line 310 and the second drive signal line 320 can be made of metal conductive materials such as copper, copper alloy, or other types of conductive materials, and the embodiments of the present disclosure are not limited to this. For example, taking the first drive signal line 310 and the second drive signal line 320 as an example of copper metal, the thickness of the first drive signal line 310 and the second drive signal line 320 in the direction perpendicular to the base substrate 101 can be about 1.8 μm, so that the copper metal conductive layer of this thickness can be prepared by sputtering process without the need for electroplating process, thereby further reducing the preparation cost of the light-emitting substrate 10 and simplifying the preparation process. Alternatively, in some embodiments of the present disclosure, the first drive signal line 310 and the second drive signal line 320 can also be prepared by electroplating process or other suitable process methods, and the present disclosure is not limited to this. For example, the material of the first driving signal line 310 and the second driving signal line 320 may include a single-layer metal structure, or may include a metal stacked structure formed by copper metal and molybdenum metal, such as a double-layer metal structure formed by copper metal and molybdenum metal, or a triple-layer metal structure composed of molybdenum-copper-molybdenum (Mo-Cu-Mo), etc. The embodiments of the present disclosure are not limited to this.

[0124] For example, Figure 4 and Figure 5 As shown, the second drive signal line 320 in each second drive signal line group 302 includes a fourth light-emitting signal line 321 corresponding to the third light-emitting sub-unit 213 and a fifth light-emitting signal line 322 corresponding to the first light-emitting sub-unit 211, the fourth light-emitting signal line 321 is configured to be connected to the second electrode end of the third light-emitting sub-unit 213 to provide a second electrode signal corresponding to the third light-emitting sub-unit 213, and the fifth light-emitting signal line 322 is configured to be connected to the second electrode end of the first light-emitting sub-unit 211 to provide a second electrode signal corresponding to the first light-emitting sub-unit 211.

[0125] For example, the second driving signal line 320 in each second driving signal line group 302 further includes a sixth lighting signal line 323 corresponding to the second light-emitting sub-unit 212, and the sixth lighting signal line 323 is configured to be connected to the second electrode end of the second light-emitting sub-unit 212 to provide a second electrode signal corresponding to the second light-emitting sub-unit 212. For example, in each second driving signal line group 302, the sixth lighting signal line 323 can be located between the fourth lighting signal line 321 and the fifth lighting signal line 322 in the column direction R2.

[0126] For example, the fifth light emitting signal line 322 and the sixth light emitting signal line 323 can be electrically connected to each other to transmit the same second electrode signal, thereby reducing the transmission resistance of the second electrode signal in the light emitting substrate 10 and improving the stability of the second electrode signal in the light emitting substrate 10. Figure 4As shown, in each second driving signal line group 302, the sixth light-emitting signal line 323 can be connected to the fifth light-emitting signal line 322 through, for example, a connecting portion 324 located between the sixth light-emitting signal line 323 and the fifth light-emitting signal line 322, and the fifth light-emitting signal line 322, the sixth light-emitting signal line 323 and the connecting portion 324 can be integrally arranged, thereby reducing the manufacturing cost of the second driving signal line group 302 and simplifying the manufacturing process. For example, further, the fourth light-emitting signal line 321 can also be integrally arranged with the fifth light-emitting signal line 322 and the sixth light-emitting signal line 323, thereby further reducing the manufacturing cost of the second driving signal line group 302 and simplifying the manufacturing process, and the embodiments of the present disclosure are not limited to this.

[0127] For example, each second driving signal line group 302 further includes a plurality of groups of conductive portions corresponding to each light emitting unit 201 in a row of light emitting units, and each group of conductive portions includes a first conductive portion 325 and a second conductive portion 326. For example, the first conductive portion 325 and the second conductive portion 326 can refer to Figure 4 As shown in, or you can also refer to Fig. 9 as shown in .

[0128] The first conductive portion 325 is connected to the fourth light-emitting signal line 321 and extends from the fourth light-emitting signal line 321 toward a side of the third light-emitting sub-unit 213 in the light-emitting unit 201 corresponding to the first conductive portion 325, so that the orthographic projection of the first conductive portion 325 on the base substrate 101 at least partially overlaps with the orthographic projection of the third light-emitting sub-unit 213 in the corresponding light-emitting unit 201 on the base substrate 101.

[0129] For example, Figure 4 or Fig. 9 Taking the situation shown in as an example, the first conductive portion 325 can be connected to the fourth light-emitting signal line 321 and integrally arranged, and the first conductive portion 325 extends upward from the fourth light-emitting signal line 321, for example, to form a structure approximately in a semicircular shape, and the orthographic projection of the third light-emitting sub-unit 213 on the base substrate 101 can be located in the area surrounded by the outer contour of the orthographic projection of the first conductive portion 325 on the base substrate 101, so that the first conductive portion 325 can be used to block light at the light source center (and a position close to the light source center) of the third light-emitting sub-unit 213, thereby improving the uniformity of light selection in the entire light-emitting substrate 10 and improving the uniformity of the emitted light from the light-emitting substrate 10.

[0130] The second conductive portion 326 is connected to the fifth light-emitting signal line 322 and extends from the fifth light-emitting signal line 322 toward a side close to the first light-emitting sub-unit 211 (and the second light-emitting sub-unit 212) in the light-emitting unit 201 corresponding to the second conductive portion 326, so that the orthographic projection of the second conductive portion 326 on the base substrate 101 at least partially overlaps with the orthographic projection of the first light-emitting sub-unit 211 (and the second light-emitting sub-unit 212) in the corresponding light-emitting unit 201 on the base substrate 101.

[0131] For example, Figure 4 or Fig. 9 Taking the situation shown in as an example, the second conductive portion 326 can be connected to the fifth light-emitting signal line 322 and integrally arranged, and the second conductive portion 326 extends downward from the fifth light-emitting signal line 322, for example, to form a structure approximately in a semicircular shape, and the orthographic projection of the first light-emitting sub-unit 211 (and the second light-emitting sub-unit 212) on the base substrate 101 can be located in the area surrounded by the outer contour of the orthographic projection of the second conductive portion 326 on the base substrate 101, so that the second conductive portion 326 can be used to block light at the center of the light source (and a position close to the center of the light source) of the first light-emitting sub-unit 211 (and the second light-emitting sub-unit 212), thereby improving the uniformity of light selection in the entire light-emitting substrate 10 and improving the uniformity of the emitted light of the light-emitting substrate 10.

[0132] For example, in Figure 4 In the illustrated embodiment, in a direction perpendicular to the base substrate 101, the overlapping portions between the second drive signal line group 302 and the light-emitting unit 201 (e.g., the first conductive portion 325 and the second conductive portion 326) can be designed as a routing structure that is approximately circular or semicircular, so that the transmission load of the second electrode signal in the light-emitting substrate 10 can be reduced by the semicircular routing portion, and the central portion of the light emitted from the light-emitting unit 201 can be appropriately shielded by the semicircular routing portion to reduce the light intensity of the corresponding portion of the light-emitting substrate 10, thereby further improving the uniformity of the light emitted from the light-emitting substrate 10 as a whole.

[0133] Figure 6 This is a schematic plan view of another light-emitting substrate provided in some embodiments of the present disclosure. It should be noted that: Figure 6 The other structures of the light emitting substrate 20 except the conductive structure 401 are the same as those shown in FIG. Figure 1 The light emitting substrate 10 shown is basically the same or similar, and will not be described in detail here.

[0134] For example, Figure 6As shown, the light-emitting substrate 20 also includes a plurality of conductive structures 401 corresponding to the plurality of light-emitting units 201 one by one. For example, the orthographic projection of each light-emitting unit 201 on the base substrate 101 is located within the area surrounded by the outer contour of the orthographic projection of the conductive structure 401 corresponding to the light-emitting unit 201 on the base substrate 101. Along the direction from the center to the edge of each conductive structure 401, that is, along the direction from near to far from the center of the light-emitting unit 201, the conductive structure 401 is divided into a plurality of regions, and the transmittance of each of the plurality of regions is different from each other. Therefore, the plurality of regions of the conductive structure 401 can be used to further optimize the uniform light design of the outgoing light of the light-emitting substrate 20, thereby better solving the problem of uneven local brightness of the light-emitting substrate 20, and further optimizing the uniformity of the overall outgoing light of the light-emitting substrate 20.

[0135] Fig. 7A and 7B A schematic diagram of a method for dividing regions of a conductive structure provided in some embodiments of the present disclosure, Figure 8 A schematic diagram of a specific example of a conductive structure provided in some embodiments of the present disclosure, Fig. 9 for Figure 8 FIG. 4 is a schematic partial enlarged diagram of the area AR2 shown in FIG.

[0136] For example, refer to Fig. 7A , Figure 7B as well as Figure 8 As shown, the conductive structure 401 can be divided into a plurality of regions R1, R2, R3 and R4, and the transmittance of each region of the conductive structure 401 in the plurality of regions R1, R2, R3 and R4 is different from each other. For example, the light emitted by the light-emitting unit 201 can be reflected by a structure having a reflective function such as a reflective layer RL, and the reflected light then passes through the conductive structure 401 and is emitted from the light-emitting substrate 20 as an outgoing light. For example, taking each light-emitting sub-unit 210 in the light-emitting unit 201 as a point light source, in a structure in which the light-emitting substrate 20 adopts reflective light emission, since the light emitted by each light-emitting sub-unit 210 is reflected by a structure having a reflective function such as a reflective layer RL, the light reflected to different regions R1, R2, R3 and R4 of the conductive structure 401 will show a gradual attenuation change. For example, the intensity of the reflected light received in the area R1 of the conductive structure 401 is the highest, and the intensity of the reflected light received in the area R4 of the conductive structure 401 is the lowest. Therefore, by correspondingly adjusting the transmittance of different areas R1, R2, R3 and R4 of the conductive structure 401, the multiple areas R1, R2, R3 and R4 of the conductive structure 401 can be used to repeatedly reflect the light reflected by the reflective layer RL, and finally reduce the difference in light intensity of the light emitted from each area of ​​the conductive structure 401, thereby improving the uniformity of the emitted light of the light-emitting substrate 20.

[0137] For example, the center of each conductive structure 401 and the center of the light-emitting unit 201 corresponding to the conductive structure 401 overlap in a direction perpendicular to the base substrate 101, which is beneficial for uniform light design of the light emitted by the light-emitting unit 201 corresponding to the conductive structure 401 through the conductive structure 401, thereby improving the uniformity of the output light of the light-emitting substrate 20.

[0138] For example, the shapes of the orthographic projections of the multiple conductive structures 401 on the base substrate 101 can be substantially the same, and the orthographic projections of the multiple conductive structures 401 on the base substrate 101 do not overlap with each other, so that the light emitted by the multiple light-emitting units 201 in the light-emitting substrate 20 can be subjected to a basically consistent uniform light effect, further improving the uniformity of the output light of the light-emitting substrate 20.

[0139] For example, Fig. 7A , Figure 7B and Figure 8 Taking the multiple regions R1, R2, R3 and R4 of the conductive structure 401 shown in the figure as an example, along the direction from the center to the edge of each conductive structure 401, the transmittance of the multiple regions R1, R2, R3 and R4 of the conductive structure 401 gradually increases, that is, the transmittance of the region R2 of the conductive structure 401 is higher than the transmittance of the region R1 of the conductive structure 401, the transmittance of the region R3 of the conductive structure 401 is higher than the transmittance of the region R2 of the conductive structure 401, and the transmittance of the region R4 of the conductive structure 401 is higher than the transmittance of the region R3, thereby making the conductive structure 401 and the light amount of the reflected light reflected by the reflective layer RL to the different regions R1, R2, R3 and R4 of the conductive structure 401 cooperate with each other, thereby realizing the uniform light design of the outgoing light passing through the conductive structure 401.

[0140] For example, each conductive structure 401 in the light-emitting substrate 20 may be a centrally symmetrical structure, thereby further improving the uniform light effect on the outgoing light passing through the conductive structure 401. For example, the overall profile of the conductive structure 401 may be Figure 6 or Figure 8 The circle shown in , or it can also be Fig.10 The conductive structure 401 may be a regular polygon as shown in the figure, such as a regular hexagon; or, in some other embodiments of the present disclosure, the conductive structure 401 may also adopt other suitable regular polygonal shapes, such as a square, a regular octagon, etc., or may also adopt other suitable regular shapes or irregular shapes such as a triangle, etc. The embodiments of the present disclosure do not limit the specific shape and contour of the conductive structure 401.

[0141] For example, Figure 6 and Figure 8 As an example, the overall outline of the conductive structure 401 shown in FIG. 4 is a circle. Figure 6, Figure 8 and Fig. 9 As shown, each conductive structure 401 includes a first conductive substructure 4011 and a second conductive substructure 4012 that are opposite to each other in the column direction R2, and the first conductive substructure 4011 and the second conductive substructure 4012 are axially symmetrical with respect to the center of the conductive structure 401 along the row direction R1 to form the conductive structure 401. The first conductive substructure 4011 and the second conductive substructure 4012 are spaced apart from each other and insulated. The orthogonal projection of the first conductive substructure 4011 on the substrate substrate 101 is located on a side of the orthogonal projection of the fourth light-emitting signal line 321 on the substrate substrate 101 that is away from the orthogonal projection of the fifth light-emitting signal line 322 on the substrate substrate 101, and the orthogonal projection of the second conductive substructure 4012 on the substrate substrate 101 is located on a side of the orthogonal projection of the fifth light-emitting signal line 322 on the substrate substrate 101 that is away from the orthogonal projection of the fourth light-emitting signal line 321 on the substrate substrate 101.

[0142] For example, in some embodiments of the present disclosure, the orthographic projection of the first conductive substructure 4011 on the substrate substrate 101 may at least partially overlap with the orthographic projection of the third light-emitting subunit 213 on the substrate substrate 101, and the orthographic projection of the second conductive substructure 4012 on the substrate substrate 101 may at least partially overlap with the orthographic projection of the first light-emitting subunit 211 (and the second light-emitting subunit 212) on the substrate substrate 101.

[0143] For example, the first conductive substructure 4011 is connected to the fourth light-emitting signal line 321, and the second conductive substructure 4012 is connected to the fifth light-emitting signal line 322, thereby reducing the transmission load of the second electrode signal on the fourth light-emitting signal line 321 and the transmission load of the second electrode signal on the fifth light-emitting signal line 322 (and the sixth light-emitting signal line 323 electrically connected to the fifth light-emitting signal line 322), thereby optimizing the overall performance of the light-emitting substrate 20.

[0144] It should be noted that in some other embodiments of the present disclosure, the first conductive substructure 4011 and the second conductive substructure 4012 may also be respectively configured to receive other types of electrical signals, for example, they may be grounded or in a floating state, etc., and the embodiments of the present disclosure are not limited to this.

[0145] For example, the first conductive substructure 4011 can be integrally arranged with the fourth light-emitting signal line 321, and the second conductive substructure 4012 can be integrally arranged with the fifth light-emitting signal line 322, thereby further reducing the preparation cost of the light-emitting substrate 20, reducing the number of mask structures required in the preparation process, and simplifying the preparation process.

[0146] For example, Figure 6 , Figure 8 and Fig. 9As shown, the first conductive substructure 4011 includes a plurality of first semi-annular portions 4021 sequentially arranged along the direction from the center to the edge of each conductive structure 401, and the two ends of each first semi-annular portion 4021 are respectively connected to the fourth signal line 321, so that two adjacent first semi-annular portions 4021 are electrically connected to each other and form an open area. Among the plurality of first semi-annular portions 4021, the distance between two adjacent first semi-annular portions 4021 located in different areas of the conductive structure 401 gradually increases along the direction from the center to the edge of each conductive structure 401. The second conductive substructure 4012 includes a plurality of second semi-annular portions 4022 sequentially arranged along the direction from the center to the edge of each conductive structure 401, and the two ends of each second semi-annular portion 4022 are respectively connected to the fifth signal line 322, so that two adjacent second semi-annular portions 4022 are electrically connected to each other and form an open area. Among the plurality of second semi-annular portions 4022 , the distance between two adjacent second semi-annular portions 4022 located in different regions of the conductive structure 401 gradually increases in a direction from the center to the edge of each conductive structure 401 .

[0147] For example, the region R1 of the first conductive substructure 4011 may include, for example, five first semi-annular portions 4021, and the region R1 of the second conductive substructure 4012 may include, for example, five second semi-annular portions 4022. For example, the widths of the five first semi-annular portions 4021 and the five second semi-annular portions 4022 may be set to 40 μm. For the five first semi-annular portions 4021, along the direction from the center of the conductive structure 401 to the edge, the spacings between adjacent first semi-annular portions 4021 may be set to 12.5 μm, 12.5 μm, 15 μm, and 15 μm, respectively; for the five second semi-annular portions 4022, along the direction from the center of the conductive structure 401 to the edge, the spacings between adjacent second semi-annular portions 4022 may be set to 12.5 μm, 12.5 μm, 15 μm, and 15 μm, respectively. For example, for the area R1 of the conductive structure 401, since the intensity of light reflected by the light-emitting unit 201 is the largest and the amount of reflected light is the largest, the arrangement density of the first semi-annular portion 4021 and the second semi-annular portion 4022 included in the area R1 of the conductive structure 401 is relatively the largest, and the opening area formed is relatively the smallest. For example, the opening rate of the area R1 of the conductive structure 401 is about 15%, so that most of the light reflected to the area R1 of the conductive structure 401 can be further reflected again to the area R2 of the conductive structure 401 through the first semi-annular portion 4021 and the second semi-annular portion 4022.

[0148] For example, the region R2 of the first conductive substructure 4011 may include, for example, 7 first semi-annular portions 4021, and the region R2 of the second conductive substructure 4012 may include, for example, 7 second semi-annular portions 4022. For example, the widths of the 7 first semi-annular portions 4021 may be set to 40 μm, 50 μm, 50 μm, 52.5 μm, 52.5 μm, 55 μm, and 55 μm, respectively; and the widths of the 7 second semi-annular portions 4022 may be set to 40 μm, 50 μm, 50 μm, 52.5 μm, 52.5 μm, 55 μm, and 55 μm, respectively. For the 7 first semi-annular parts 4021, along the direction from the center to the edge of the conductive structure 401, the spacing between adjacent first semi-annular parts 4021 can be set to 20μm, 20μm, 22.5μm, 22.5μm, 25μm and 27.5μm respectively; for the 7 second semi-annular parts 4022, along the direction from the center to the edge of the conductive structure 401, the spacing between adjacent second semi-annular parts 4022 can be set to 20μm, 20μm, 22.5μm, 22.5μm, 25μm and 27.5μm respectively. For example, for the region R2 of the conductive structure 401, since the region R2 is close to the region R1, it is relatively close to the center of the light-emitting unit 201, and there are light directly reflected by the light-emitting unit 201 and light reflected by the first semi-annular portion 4021 and the second semi-annular portion 4022 of the region R1, and the light intensity and light quantity are relatively strong, so the arrangement density of the first semi-annular portion 4021 and the second semi-annular portion 4022 included in the region R2 of the conductive structure 401 can be smaller than the arrangement density of the first semi-annular portion 4021 and the second semi-annular portion 4022 included in the region R1. For example, the aperture ratio of the region R2 of the conductive structure 401 can be about 27.5%, so that most of the light received by the region R2 is further reflected again to the region R3 of the conductive structure 401.

[0149] For example, the region R3 of the first conductive substructure 4011 may include five first semi-annular portions 4021, and the region R3 of the second conductive substructure 4012 may include five second semi-annular portions 4022. For example, the widths of the five first semi-annular portions 4021 may be set to 60 μm, 60 μm, 65 μm, 65 μm, and 70 μm, respectively; and the widths of the five second semi-annular portions 4022 may be set to 60 μm, 60 μm, 65 μm, 65 μm, and 70 μm, respectively. For the five first semi-annular parts 4021, the spacing between adjacent first semi-annular parts 4021 along the direction from the center to the edge of the conductive structure 401 can be set to 40μm, 50μm, 60μm and 70μm respectively; for the five second semi-annular parts 4022, the spacing between adjacent second semi-annular parts 4022 along the direction from the center to the edge of the conductive structure 401 can be set to 40μm, 50μm, 60μm and 70μm respectively. For example, for the region R3 of the conductive structure 401, since the intensity of the light directly reflected by the light-emitting unit 201 received by the region R3 is average, but there is light reflected again through the R2 region, the spacing between adjacent first semi-annular parts 4021 and the spacing between adjacent second semi-annular parts 4022 of the region R3 can be gradually increased, thereby 38% of the light received by the region R3 is emitted as the outgoing light of the light-emitting substrate 20, and 62% of the received light is further reflected again to the region R4 of the conductive structure 401.

[0150] For example, the region R4 of the first conductive substructure 4011 may include, for example, three first semi-annular portions 4021, and the region R4 of the second conductive substructure 4012 may include, for example, three second semi-annular portions 4022. For example, the widths of the three first semi-annular portions 4021 may be set to 50 μm, respectively; and the widths of the three second semi-annular portions 4022 may be set to 50 μm, respectively. For the three first semi-annular portions 4021, along the direction from the center of the conductive structure 401 to the edge, the spacings between adjacent first semi-annular portions 4021 may be set to 90 μm and 110 μm, respectively; and for the three second semi-annular portions 4022, along the direction from the center of the conductive structure 401 to the edge, the spacings between adjacent second semi-annular portions 4022 may be set to 90 μm and 110 μm, respectively. For example, the aperture ratio of the region R4 of the conductive structure 401 can be designed to be about 65%, so that most of the light received by the region R4 is emitted as the outgoing light of the light-emitting substrate 20, and a small amount of light is further reflected to the Fig. 7A , Figure 7B as well as Figure 8 Region R5 shown.

[0151] For example, Figure 8As shown, the first semi-annular portion 4021 or the second semi-annular portion 4022 may not be provided in the region R5. Since the region R5 is far from the center of the light emitting unit 201, the light intensity and the amount of light reaching the region R5 after multiple reflections are weak, for example, without considering the light loss, the light reflected to the region R5 only accounts for 13% of the light emitted by the light emitting unit 201. Therefore, after the light reflected to the region R5 by the first semi-annular portion 4021 and the second semi-annular portion 4022 of the region R4 are combined, the light emitted by the region R5 accounts for about 26% of the light emitted by the light emitting unit 201, which is similar to the region 4.

[0152] Thus, by respectively setting the width and spacing of the first semi-annular portion 4021 and the second semi-annular portion 4022 of each region R1, R2, R3, and R4 of the conductive structure 401, the transmittance of each region of the conductive structure 401 can be adjusted. For example, if the aperture ratio is used to represent the transmittance of each region, the light loss of region R1 of the conductive structure 401 is almost 0, so the aperture ratio of the region R1 should be about 8% smaller than the aperture ratio of other regions. Since the loss of light reflected by each region of the conductive structure 401 is about 1% to 3%, in order to keep the emitted light of the light-emitting substrate 20 relatively uniform as a whole, the ratio between the emitted light amount of each region R1, R2, R3, R4, and region R5 of the conductive structure 401 and the total light amount provided by the light-emitting unit 201 can be designed to be 15%, 23%, 24%, 25%, and 26%, respectively. In summary, the transmittance of regions R1 to R5 and the ratio of the amount of emitted light to the total amount of light provided by the light-emitting unit 201 are as follows: the transmittance of region R1 is 15%, so 15% of the light is used as the emitted light, and 85% of the light is reflected to region R2; the transmittance of region R2 is 27.1%, so 85%×27.1%=23% of the light is used as the emitted light, and 1-15%-23%=62% of the light is reflected to region R3; the transmittance of region R3 is 38.6%, so 62%×38 .6%=24% of the light is used as the outgoing light, and 1-15%-23%-24%=38% of the light is reflected to area R4; the transmittance of area R3 is 66%, so 38%×66%=25% of the light is used as the outgoing light, and 1-15%-23%-24%-25%=13% of the light is reflected to area R5; the transmittance of area R5 is 100%, but since there may be overlap between the light emitted by two adjacent light-emitting units 201, the light output of area R5 is 13%×2=26%.

[0153] For example, after determining the different transmittances of each area of ​​the conductive structure 401, the transmittance of each area of ​​the conductive structure 401 can be achieved by adjusting the duty ratio of the first semi-annular part 4021 and the second semi-annular part 4022 of each area, thereby improving the uniformity of the light output effect from area R1 to area R5.

[0154] For example, the width of the first semi-annular portion 4021 and the second semi-annular portion 4022 can be set to be approximately the width of the first drive signal line 310 or the second drive signal line 320, for example, can be set to be approximately 50 μm. In addition, since the first semi-annular portion 4021 and the second semi-annular portion 4022 are easily visible to the naked eye when the width of the first semi-annular portion 4021 and the second semi-annular portion 4022 is greater than 100 μm, the width of the first semi-annular portion 4021 and the second semi-annular portion 4022 in the region R1 to the region R4 can be increased from 40 μm, so that the maximum width reached by the increase does not exceed 70 μm. Furthermore, for the spacing between adjacent first semi-annular portions 4021 and the spacing between adjacent second semi-annular portions 4022 in regions R1 to R4, the spacing between adjacent first semi-annular portions 4021 and the spacing between adjacent second semi-annular portions 4022 can be increased from 12.5 μm based on the process requirements for the thickness of the first semi-annular portions 4021 and the second semi-annular portions 4022, and during the increasing process, if the light transmittance of a certain region of the conductive structure 401 does not match the expected value, the spacing between adjacent first semi-annular portions 4021 and the spacing between adjacent second semi-annular portions 4022 can be continuously kept consistent, or the spacing between adjacent first semi-annular portions 4021 and the spacing between adjacent second semi-annular portions 4022 can be increased in a gradient. Thus, the light uniformity of the light-emitting substrate 20 can be further improved to about 80%.
