[0045] A second aspect of the present invention provides a display substrate, comprising: a substrate and a plurality of sub-pixels and a plurality of data lines disposed on the substrate, wherein the sub-pixels include a sub-pixel driving circuit and a light-emitting element coupled to each other;

[0046] The plurality of sub-pixels include a plurality of sub-pixel driving circuits divided into a plurality of driving circuit columns.

The data line is coupled to each sub-pixel driving circuit in the corresponding column of driving circuits. Since the light-emitting elements coupled to each sub-pixel driving circuit in the column of driving circuits coupled to the data line have the same light emission color, when the shift register unit scans the sub-pixels row by row, that is, when the data line sequentially provides data signals to a column of sub-pixels, the voltage variation range of the data signal transmitted by the data line is very small or constant. Thus, the driving chip does not need to repeatedly switch and charge the data signal, ensuring that the data line can provide the corresponding data range of data signals to its coupled sub-pixels, thereby effectively reducing the power consumption of the driving chip and the overall power consumption of the display product.

[0053] Therefore, the technical solution provided by the present invention achieves the technical effect of reducing the power consumption of the driver chip and the overall power consumption of the display product by implementing the diamond arrangement. Attached Figure Description

[0091] To further illustrate the display substrate and display device provided in the embodiments of the present invention, a detailed description is provided below with reference to the accompanying drawings.

[0092] Research has revealed that in related technologies, within the multiple columns of sub-pixels in a display product, sub-pixels within the same column may have different colors. Since the same column of sub-pixels receives data signals via the same data line, and different colored sub-pixels require different ranges of data signals, the driver chip needs to repeatedly switch and charge the data signal during the shift register unit's row-by-row scanning (i.e., as the data line sequentially provides data signals to a column of sub-pixels). This ensures the data line can provide the corresponding data range for sub-pixels of different colors. This increases the power consumption of the driver chip, leading to an increase in the overall power consumption of the display product.

[0093] Please see Figure 3 and Figure 4 This invention provides a display substrate, comprising: a substrate and a plurality of sub-pixels and a plurality of data lines DA disposed on the substrate. The sub-pixels include sub-pixel driving circuits (e.g., red sub-pixel driving circuit P_R, green sub-pixel driving circuit P_G and blue sub-pixel driving circuit P_B) and light-emitting elements (e.g., red light-emitting element R, green light-emitting element G and blue light-emitting element B) coupled to each other.

[0094] The plurality of sub-pixels, including the plurality of sub-pixel driving circuits, are divided into multiple columns of driving circuits (e.g., first driving circuit column QL1 and second driving circuit column QL2). Each column of driving circuits includes a plurality of the sub-pixel driving circuits arranged along a first direction. The light-emitting elements coupled to each sub-pixel driving circuit in the same column of driving circuits have the same light emission color. The data line DA is coupled to each sub-pixel driving circuit in the corresponding column of driving circuits.

[0095] The multi-column drive circuit column includes multiple first drive circuit columns QL1 and multiple second drive circuit columns QL2, wherein the first drive circuit columns QL1 and the second drive circuit columns QL2 are alternately arranged along a second direction, and the second direction intersects with the first direction;

[0096] The light-emitting elements coupled to the first driving circuit column QL1 are arranged along the first direction to form a first light-emitting element column FL1; the odd-numbered light-emitting elements coupled to the second driving circuit column QL2 are alternately arranged with the even-numbered light-emitting elements coupled to the adjacent second driving circuit column QL2 along the first direction to form a second light-emitting element column FL2; the second light-emitting element column FL2 and the first light-emitting element column FL1 are alternately arranged along the second direction; the light-emitting elements in the first light-emitting element column FL1 and the light-emitting elements in the second light-emitting element column FL2 are at least partially offset along the first direction, for example: Figure 3 The red light-emitting element R and the green light-emitting element G, as well as the blue light-emitting element B and the green light-emitting element G.

[0097] For example, the display substrate includes a plurality of sub-pixels, and the plurality of sub-pixel driving circuits included in the plurality of sub-pixel ...

[0098] For example, the sub-pixel includes a sub-pixel driving circuit and a light-emitting element. The sub-pixel driving circuit is coupled to the anode of the light-emitting element and is used to provide a driving signal to the light-emitting element to drive it to emit light.

[0099] For example, the display substrate includes multiple data lines DA, each of which corresponds to one of the multiple columns of driving circuits, and each data line DA is coupled to a sub-pixel driving circuit in the corresponding column of driving circuits.

[0100] For example, the multi-column driving circuit array includes multiple first driving circuit columns QL1 and multiple second driving circuit columns QL2, which are alternately arranged along a second direction. The color of the light-emitting element coupled to the first driving circuit column QL1 is different from the color of the light-emitting element coupled to the second driving circuit column QL2. For example, the first driving circuit column QL1 is coupled to a green light-emitting element G, a first portion of the multiple second driving circuit columns QL2 is coupled to a red light-emitting element R, and a second portion of the multiple second driving circuit columns QL2 is coupled to a blue light-emitting element B, but it is not limited to this.

[0101] For example, the light-emitting elements coupled to the first driving circuit column QL1 are arranged along the first direction to form a first light-emitting element column FL1. All the light-emitting elements included in the plurality of first light-emitting element columns FL1 can be divided into multiple light-emitting element rows, each light-emitting element row including multiple light-emitting elements arranged along the second direction and all of the same color, such as green light-emitting elements, but not limited to this.

[0102] For example, in each pair of adjacent second driving circuit columns QL2, the odd-numbered light-emitting elements coupled to one second driving circuit column QL2 and the even-numbered light-emitting elements coupled to the other second driving circuit column QL2 are alternately arranged along the first direction to form a second light-emitting element column FL2. All the light-emitting elements included in the plurality of second light-emitting element columns FL2 can be divided into multiple rows of light-emitting elements, each row of light-emitting elements including multiple light-emitting elements arranged along the second direction and with alternating colors, such as red light-emitting elements and blue light-emitting elements, but not limited to this.

[0103] For example, the second light-emitting element column FL2 and the first light-emitting element column FL1 are alternately arranged along the second direction; the light-emitting elements in the first light-emitting element column FL1 and the light-emitting elements in the second light-emitting element column FL2 are at least partially offset along the first direction. Rows of light-emitting elements formed by the light-emitting elements included in a plurality of the first light-emitting element columns FL1 are alternately arranged with rows of light-emitting elements formed by the light-emitting elements included in a plurality of the second light-emitting element columns FL2 along the first direction.

[0104] For example, when the sub-pixels are arranged in the above layout, two adjacent green light-emitting elements, one red light-emitting element and one blue light-emitting element can jointly form a light-emitting element repeating unit, which is formed in a diamond arrangement, i.e., a diamond arrangement.

[0105] As can be seen from the specific structure of the display substrate described above, in the display substrate provided by the embodiments of the present invention, the light-emitting elements of the plurality of sub-pixels can form a repeating unit of light-emitting elements in a diamond arrangement. Simultaneously, the plurality of sub-pixel driving circuits of the plurality of sub-pixels are divided into multiple columns of driving circuits. Each column of driving circuits includes a plurality of sub-pixel driving circuits arranged along a first direction. The light-emitting elements coupled to each sub-pixel driving circuit in the same column of driving circuits have the same light emission color. The data line DA is coupled to each sub-pixel driving circuit in the corresponding column of driving circuits. Since the light-emitting elements coupled to each sub-pixel driving circuit in the column of driving circuits coupled to the data line DA have the same light emission color, when the shift register unit scans the sub-pixels row by row, that is, when the data line DA sequentially provides data signals to a column of sub-pixels, the voltage change range of the data signal transmitted by the data line DA is very small or constant. Thus, the driving chip does not need to repeatedly switch and charge the data signal to ensure that the data line DA can provide data signals within the corresponding data range to its coupled sub-pixels, thereby effectively reducing the power consumption of the driving chip and the overall power consumption of the display product.

[0106] Therefore, in the display substrate provided by the embodiments of the present invention, by implementing a diamond arrangement, the power consumption of the driving chip is reduced, and the overall power consumption of the display product is reduced.

[0107] like Figure 3 and Figure 4 As shown, in some embodiments, the plurality of sub-pixel driving circuits included in the plurality of sub-pixels are divided into multiple rows of driving circuits QH, and each row of driving circuits QH includes a plurality of the sub-pixel driving circuits arranged along the second direction.

[0108] The light-emitting elements coupled to the driving circuits of the odd-numbered sub-pixels in the driving circuit row QH are arranged along the second direction to form a first light-emitting element row FH1; the light-emitting elements coupled to the driving circuits of the even-numbered sub-pixels in the driving circuit row QH are arranged along the second direction to form a second light-emitting element row FH2; along the first direction, the first light-emitting element row FH1 and the second light-emitting element row FH2 are arranged alternately; the light-emitting elements in the first light-emitting element row FH1 and the light-emitting elements in the second light-emitting element row FH2 are at least partially offset along the second direction.

[0109] For example, the first row of light-emitting elements FH1 includes only green light-emitting elements G, and the second row of light-emitting elements FH2 includes red light-emitting elements R and blue light-emitting elements B arranged alternately along the second direction. Alternatively, the first row of light-emitting elements FH1 includes red light-emitting elements R and blue light-emitting elements B arranged alternately along the second direction, and the second row of light-emitting elements FH2 includes only green light-emitting elements G.

[0110] For example, the light-emitting elements in the first row of light-emitting elements FH1 and the light-emitting elements in the second row of light-emitting elements FH2 are at least partially offset along the second direction, and the light-emitting elements in the first row of light-emitting elements FH1 and the light-emitting elements in the second row of light-emitting elements FH2 are at least partially offset along the first direction.

[0111] In the display substrate provided in the above embodiments, the above arrangement method can achieve the technical effect of reducing the power consumption of the driver chip and reducing the overall power consumption of the display product while realizing the diamond arrangement.

[0112] like Figure 3 and Figure 4 As shown, in some embodiments, the first driving circuit column QL1 is coupled to a first color light-emitting element, a first portion of the plurality of second driving circuit columns QL2 is coupled to a second color light-emitting element, and a second portion of the plurality of second driving circuit columns QL2 is coupled to a third color light-emitting element.

[0113] The first light-emitting element column FL1 includes a plurality of first-color light-emitting elements arranged along the first direction; the second light-emitting element column FL2 includes second-color light-emitting elements and third-color light-emitting elements arranged alternately along the first direction.

[0114] For example, the first color light-emitting element includes a green light-emitting element G, the second color light-emitting element includes a red light-emitting element R, and the third color light-emitting element includes a blue light-emitting element B, but is not limited thereto.

[0115] For example, in adjacent second light-emitting element columns FL2: the odd-numbered light-emitting element in one column FL2 is a second-color light-emitting element, and the even-numbered light-emitting element is a third-color light-emitting element; in another column FL2, the even-numbered light-emitting element is a second-color light-emitting element, and the odd-numbered light-emitting element is a third-color light-emitting element. A column of first light-emitting elements FL1, a column of second light-emitting elements FL2, a column of first light-emitting elements FL1, and a column of second light-emitting elements FL2 arranged sequentially along the second direction, i.e., a total of four columns of light-emitting elements, form a column repeating unit. The display substrate includes multiple such column repeating units.

[0116] In the display substrate provided in the above embodiments, the above arrangement method can achieve the technical effect of reducing the power consumption of the driver chip and reducing the overall power consumption of the display product while realizing the diamond arrangement.

[0117] like Figure 3 and Figure 4As shown, in some embodiments, one row of the first light-emitting element row FH1 and the second light-emitting element row FH2 includes a plurality of first color light-emitting elements arranged along the second direction; the other row of the first light-emitting element row FH1 and the second light-emitting element row FH2 includes second color light-emitting elements and third color light-emitting elements arranged alternately along the second direction.

[0118] Taking the first row of light-emitting elements FH1 as including a plurality of first-color light-emitting elements arranged along the second direction, and the second row of light-emitting elements FH2 as including second-color light-emitting elements and third-color light-emitting elements alternately arranged along the second direction as an example: For instance, in adjacent rows of second light-emitting elements FH2: the odd-numbered light-emitting element in one row of second light-emitting element FH2 is a second-color light-emitting element, and the even-numbered light-emitting element is a third-color light-emitting element; in another row of second light-emitting element FH2, the even-numbered light-emitting element is a second-color light-emitting element, and the odd-numbered light-emitting element is a third-color light-emitting element. A row of first light-emitting elements FH1, a row of second light-emitting elements FH2, a row of first light-emitting elements FH1, and a row of second light-emitting elements FH2 arranged sequentially along the first direction, i.e., a total of four rows of light-emitting elements, form a row repeating unit, and the display substrate includes a plurality of such row repeating units.

[0119] In the display substrate provided in the above embodiments, the above arrangement method can achieve the technical effect of reducing the power consumption of the driver chip and reducing the overall power consumption of the display product while realizing the diamond arrangement.

[0120] like Figure 16 , Figure 19 , Figure 23 , Figure 24 , Figure 29 , Figure 30 , Figure 35 and Figure 36 As shown, in some embodiments, the light-emitting element includes an anode pattern, which includes coupled anode main bodies (e.g., first anode main body ANO11, second anode main body ANO12, third anode main body ANO13, and fourth anode main body ANO14) and anode extensions (e.g., first anode extension ANO21, second anode extension ANO22, third anode extension ANO23, and fourth anode extension ANO24); the sub-pixel also includes conductive connection structures (e.g., first conductive connection structure 31, second conductive connection structure 32, third conductive connection structure 33, and fourth conductive connection structure 34), and the sub-pixel driving circuit is coupled to the anode extensions through the conductive connection structures.

[0121] For example, the anode body and the anode extension are formed as an integral structure. At least a portion of the anode body is located in the pixel opening region of the sub-pixel. The anode extension is located in the pixel non-opening region of the sub-pixel.

[0122] For example, the anode body may be circular, elliptical, hexagonal, quadrilateral, pentagonal, etc., but is not limited to these.

[0123] It is worth noting that the light-emitting elements in the rows and columns of light-emitting elements mentioned in the above embodiments, which are arranged in the first direction or the second direction, can all be viewed with reference to the anode body portion in the light-emitting element. That is, the anode body portion in the anode pattern of the light-emitting element is arranged in the first direction or the second direction.

[0124] For example, the conductive connection structure can be a single-layer structure, a double-layer structure, or a multi-layer structure, depending on the specific circumstances.

[0125] For example, the conductive connection structure is located on the side of the sub-pixel driving circuit away from the substrate, and the light-emitting element is located on the side of the conductive connection structure away from the substrate.

[0126] For example, the light-emitting element may further include a light-emitting functional layer and a cathode layer, wherein the light-emitting functional layer is located between the anode pattern and the cathode layer, and the cathode layer is located on the side of the anode pattern facing away from the substrate.

[0127] In the display substrate provided in the above embodiments, the sub-pixel driving circuit is coupled to the anode extension through the conductive connection structure. By setting the conductive connection structure and the anode extension to have suitable structures and layouts, a diamond arrangement of light-emitting elements can be achieved, and the light-emitting elements coupled to a column of driving circuits coupled to the data line DA are of the same color.

[0128] like Figure 16 , Figure 19 , Figure 23 , Figure 24 , Figure 29 , Figure 30 , Figure 35 and Figure 36As shown, in some embodiments, the conductive connection structure includes at least two conductive connection portions (e.g., a first conductive connection portion 101, a second conductive connection portion 102, and a third conductive connection portion 103), and the at least two conductive connection portions are sequentially stacked along a direction away from the substrate; the sub-pixel driving circuit includes a driving transistor (i.e., a third transistor T3) and a light-emitting control transistor (i.e., a sixth transistor T6), the first electrode of the light-emitting control transistor is coupled to the second electrode of the driving transistor, and the second electrode of the light-emitting control transistor is sequentially coupled to the anode extension portion through the at least two conductive connection portions.

[0129] For example, the at least two conductive connections are coupled sequentially. The second electrode of the light-emitting control transistor is coupled to the conductive connection closest to the substrate among the at least two conductive connections, and the conductive connection furthest from the substrate among the at least two conductive connections is coupled to the anode extension.

[0130] The specific circuit structure of the sub-pixel driving circuit can vary, such as LTPS (Low Temperature Poly-Silicon) sub-pixel driving circuit, LTPO (Low Temperature Polycrystalline Oxide) sub-pixel driving circuit, etc., but is not limited to these. Specific circuit structures can be selected as 7T1C (including 7 transistors and 1 capacitor) circuit structures, 8T1C (including 8 transistors and 1 capacitor) circuit structures, 8T2C (including 8 transistors and 2 capacitors) circuit structures, etc., but are not limited to these.

[0131] The following explanation uses the LTPO subpixel driving circuit structure, specifically the 8T2C circuit structure, as an example of the subpixel driving circuit.

[0132] like Figure 1 , Figures 5 to 18 As shown, the sub-pixel driving circuit includes a first transistor T1, a second transistor T2, a third transistor T3, a fourth transistor T4, a fifth transistor T5, a sixth transistor T6, a seventh transistor T7, an eighth transistor, a first capacitor C1, and a second capacitor C2. The first transistor T1, the second transistor T2, the fourth transistor T4, and the eighth transistor T8 are NMOS transistors, while the third transistor T3, the fifth transistor T5, the sixth transistor T6, and the seventh transistor T7 are PMOS transistors.

For example, the scan signal transmitted by the third scan line G3 is the same as the scan signal transmitted by the fifth scan line G5, and the third scan line G3 and the fifth scan line G5 can be coupled to the same shift register unit in the peripheral region of the display substrate.

[0141] The first plate C11 of the first capacitor C1 is coupled to the power line VDD. The first plate C21 of the second capacitor C2 is coupled to the gate of the third transistor T3, and the second plate C22 of the second capacitor C2 is coupled to the second plate C12 of the first capacitor C1.

[0142] like Figure 7 As shown, the overlapping portion of the first active layer and the first gate metal layer forms the channel portion of the corresponding transistor.

[0143] like Figure 8 , Figure 9 and Figure 10 As shown, the first scan line G1 includes a first scan layer G11 and a second scan layer G12. The third scan line G3 includes a third scan layer G31 and a fourth scan layer G32. The fourth scan line G4 includes a fifth scan layer G41 and a sixth scan layer G42.

The second scan layer G12, the fourth scan layer G32, and the sixth scan layer G42 are fabricated using a third gate metal layer.

[0144] like Figures 11 to 24 As shown, the first adapter 41 is coupled to the first initialization signal line Vinit1 through the first via Via1, and the first adapter 41 is coupled to the first pole of the first transistor T1 through the eleventh via Via11.

[0146] The third adapter 43 is coupled to the first terminal of the fifth transistor T5 through the second via Via2. The third adapter 43 is coupled to the power line VDD located in the second source-drain metal layer through the twentieth via Via20. The power line VDD located in the second source-drain metal layer is coupled to the power line VDD located in the third source-drain metal layer through the twentieth via Via26.

[0147] The fourth adapter 44 is coupled to the second plate C22 of the second capacitor C2 through the fourth via Via4, and the fourth adapter 44 is coupled to the second electrode of the fourth transistor T4 through the twelfth via Via12.

[0148] The fifth adapter 45 is coupled to the first plate C21 of the second capacitor C2 through the fifth via Via5, and the fifth adapter 45 is coupled to the second electrode of the first transistor T1 through the thirteenth via Via13.

[0149] The sixth adapter 46 is coupled to the first terminal of the second transistor T2 through the fourteenth via Via14, and to the second terminal of the eighth transistor T8 through the fifteenth via Via15. The sixth adapter 46 is coupled to the first terminal of the third transistor T3 through the third via Via3.

[0150] The seventh adapter 47 is coupled to the first plate C11 of the first capacitor C1 through the sixth via Via6, and the seventh adapter 47 is coupled to the power line VDD located in the second source-drain metal layer through the twenty-third via Via23.

[0151] The ninth adapter 49 is coupled to the first pole of the eighth transistor T8 through the seventeenth via Via17, and the ninth adapter 49 is coupled to the third initialization signal line Vinit3 through the eighteenth via Via18.

[0152] The first conductive connection 101 is coupled to the second electrode of the sixth transistor T6 and the second electrode of the seventh transistor T7 through the seventh via Via7. The first conductive connection 101 is coupled to the second conductive connection 102 through the twenty-second via Via22. The second conductive connection 102 is coupled to the third conductive connection 103 through the twenty-fifth via Via25. The third conductive connection 103 is coupled to the anode extension ANO2 through the twenty-seventh via Via27.

[0153] The second initialization signal line Vinit2, located in the first source-drain metal layer, is coupled to the second initialization signal line Vinit2, located in the second gate metal layer, through the sixteenth via Via16. The second initialization signal line Vinit2, located in the first source-drain metal layer, is coupled to the second terminal of the seventh transistor T7 through the eighth via Via8.

[0154] like Figure 16 , Figure 19 , Figure 23 , Figure 24 , Figure 25 , Figure 29 , Figure 30 , Figure 31 , Figure 35 and Figure 36As shown, in some embodiments, the conductive connection structure includes a first conductive connection portion 101, a second conductive connection portion 102, and a third conductive connection portion 103 sequentially stacked along a direction away from the substrate; the second conductive connection portion 102 is coupled to the first conductive connection portion 101 and the third conductive connection portion 103 respectively, the first conductive connection portion 101 is coupled to the second electrode of the light-emitting control transistor, and the third conductive connection portion 103 is coupled to the anode extension;

[0155] The orthographic projection of the first conductive connection portion 101 on the substrate does not overlap with the orthographic projection of the third conductive connection portion 103 on the substrate.

[0156] For example, the orthographic projection of the first conductive connection portion 101 on the substrate does not overlap with the orthographic projection of the third conductive connection portion 103 on the substrate at least partially.

[0157] For example, the orthographic projection of the first conductive connection portion 101 on the substrate does not overlap with the orthographic projection of the third conductive connection portion 103 on the substrate.

[0158] For example, the orthographic projection of the second conductive connection portion 102 on the substrate overlaps with the orthographic projection of the first conductive connection portion 101 on the substrate, and the second conductive connection portion 102 and the first conductive connection portion 101 are electrically connected through this overlap and vias. Similarly, the orthographic projection of the second conductive connection portion 102 on the substrate overlaps with the orthographic projection of the third conductive connection portion 103 on the substrate, and the second conductive connection portion 102 and the third conductive connection portion 103 are electrically connected through this overlap and vias.

[0159] In the display device provided in the above embodiments, the conductive connection structure includes a first conductive connection portion 101, a second conductive connection portion 102, and a third conductive connection portion 103 sequentially stacked along a direction away from the substrate. By setting the structure and layout of the first conductive connection portion 101, the second conductive connection portion 102, and the third conductive connection portion 103 respectively, a more diverse layout of the conductive connection structure can be achieved. This makes the selection of the layout position of the anode pattern coupled to the conductive connection structure more flexible, thereby effectively reducing the layout difficulty of the display substrate.

[0160] In the display device provided in the above embodiments, the orthographic projection of the first conductive connection portion 101 on the substrate does not overlap with the orthographic projection of the third conductive connection portion 103 on the substrate, so that the conductive connection structure can extend a greater distance in the direction parallel to the substrate, further improving the flexibility of the layout position of the anode pattern coupled to the conductive connection structure, thereby further reducing the layout difficulty of the display substrate.

[0161] In some embodiments, the display substrate includes a first source / drain metal layer, a second source / drain metal layer, and a third source / drain metal layer sequentially stacked along a direction away from the substrate; the first conductive connection portion 101 is disposed in the same layer and with the same material as the first source / drain metal layer, the second conductive connection portion 102 is disposed in the same layer and with the same material as the second source / drain metal layer, and the third conductive connection portion 103 is disposed in the same layer and with the same material as the third source / drain metal layer.

[0162] like Figure 2 As shown, exemplarily, the display substrate includes, sequentially stacked along a direction away from the substrate 70, a buffer layer BF, a first active layer poly, a first gate insulating layer GI1, a first gate metal layer gate1, a second gate insulating layer GI2, a second gate metal layer gate2, a third gate insulating layer GI3, a second active layer ACT, a fourth gate insulating layer GI4, a third gate metal layer gate3, an interlayer insulating layer ILD, a first source / drain metal layer SD1, a passivation layer PVX, a first planarization layer PLN1, a second source / drain metal layer SD2, a second planarization layer PLN2, a third source / drain metal layer SD3, a third planarization layer PLN3, an anode layer ANO, a pixel boundary layer PDL, a light-emitting functional layer EL, a cathode layer cath, a first inorganic encapsulation layer CVD1, an organic encapsulation layer IJP, and a second inorganic encapsulation layer CVD2. Figure 5 and Figure 6 As shown, the display substrate may further include a light-shielding layer LS, which is located between the first active layer poly and the substrate 70. The light-shielding layer LS can block the channel portion of the third transistor T3, which is beneficial to improving the stability of the third transistor T3.

[0163] The above configuration allows the first conductive connection 101 to be formed simultaneously with the first source / drain metal layer in the same patterning process, the second conductive connection 102 to be formed simultaneously with the second source / drain metal layer in the same patterning process, and the third conductive connection 103 to be formed simultaneously with the third source / drain metal layer in the same patterning process. This effectively simplifies the manufacturing process of the display substrate and saves manufacturing costs.

[0164] like Figure 3 , Figure 4In some embodiments, the multi-column driving circuit columns are divided into multiple driving groups QLZ arranged along the second direction. The driving group QLZ includes adjacent first driving circuit columns QL1 and second driving circuit columns QL2. The driving circuit groups are divided into first driving units QD1 and second driving units QD2 arranged alternately along the first direction. The first driving unit QD1 includes a first sub-pixel driving circuit (e.g., green sub-pixel driving circuit P_G) and a second sub-pixel driving circuit (e.g., blue sub-pixel driving circuit P_B and red sub-pixel driving circuit P_R) arranged sequentially along the second direction. The second driving unit QD2 includes a third sub-pixel driving circuit (e.g., green sub-pixel driving circuit P_G) and a fourth sub-pixel driving circuit (e.g., blue sub-pixel driving circuit P_B and red sub-pixel driving circuit P_R) arranged sequentially along the second direction.

[0165] like Figure 16 , Figures 19 to 36 As shown, the first sub-pixel driving circuit is coupled to the first anode extension ANO21 through the first conductive connection structure 31; the second sub-pixel driving circuit is coupled to the second anode extension ANO22 through the second conductive connection structure 32; the third sub-pixel driving circuit is coupled to the third anode extension ANO23 through the third conductive connection structure 33; and the fourth sub-pixel driving circuit is coupled to the fourth anode extension ANO24 through the fourth conductive connection structure 34.

[0166] The orthographic projection of the first anode extension ANO21 on the substrate does not overlap with the orthographic projection of the second conductive connection structure 32 on the substrate; and / or, the orthographic projection of the third anode extension ANO23 on the substrate does not overlap with the orthographic projection of the fourth conductive connection structure 34 on the substrate.

[0167] It should be noted that the first sub-pixel driving circuit is located in the first sub-pixel driving circuit layout area 21. The second sub-pixel driving circuit is located in the second sub-pixel driving circuit layout area 22. The third sub-pixel driving circuit is located in the third sub-pixel driving circuit layout area 23. The fourth sub-pixel driving circuit is located in the fourth sub-pixel driving circuit layout area 24.

[0168] For example, the first conductive connection structure 31, the second conductive connection structure 32, the third conductive connection structure 33, and the fourth conductive connection structure 34 may each include a first conductive connection portion 101, a second conductive connection portion 102, and a third conductive connection portion 103. However, the specific structure of the first conductive connection portion 101 belonging to different conductive connection structures may be the same or different, the specific structure of the second conductive connection portion 102 belonging to different conductive connection structures may be the same or different, and the specific structure of the third conductive connection portion 103 belonging to different conductive connection structures may be the same or different.

[0169] For example, the light-emitting element belonging to the first anode extension ANO21 includes a green light-emitting element, the light-emitting element belonging to the second anode extension ANO22 includes a red light-emitting element or a blue light-emitting element, the light-emitting element belonging to the third anode extension ANO23 includes a green light-emitting element, and the light-emitting element belonging to the fourth anode extension ANO24 includes a red light-emitting element or a blue light-emitting element.

[0170] For example, the first anode extension ANO21 is coupled to the first anode body ANO11 to form a first anode pattern. The overlap area between the orthographic projection of the first anode body ANO11 on the substrate and the orthographic projection of the power line VDD on the display substrate on the substrate is greater than or equal to 50% of the area of ​​the first anode body ANO11.

[0171] For example, the third anode extension ANO23 is coupled to the third anode body ANO13 to form a third anode pattern. The overlap area between the orthographic projection of the third anode body ANO13 on the substrate and the orthographic projection of the power line VDD on the display substrate on the substrate is greater than or equal to 50% of the area of ​​the third anode body ANO13.

[0172] For example, the second anode extension ANO22 is coupled to the second anode body ANO12 to form a second anode pattern. The overlap area between the orthographic projection of the second anode body ANO12 on the substrate and the orthographic projection of the power line VDD on the display substrate on the substrate is less than or equal to 30% of the area of ​​the second anode body ANO12.

[0173] For example, the fourth anode extension ANO24 is coupled to the fourth anode body ANO14 to form a fourth anode pattern. The overlap area between the orthographic projection of the fourth anode body ANO14 on the substrate and the orthographic projection of the power line VDD on the display substrate on the substrate is less than or equal to 50% of the area of ​​the fourth anode body ANO14.

[0174] The above-described configuration ensures that the orthographic projection of the first anode extension ANO21 on the substrate does not overlap with the orthographic projection of the second conductive connection structure 32 on the substrate; and / or, the orthographic projection of the third anode extension ANO23 on the substrate does not overlap with the orthographic projection of the fourth conductive connection structure 34 on the substrate. This better avoids the first anode pattern and the third anode pattern occupying the layout space of adjacent anode patterns, ensuring layout reliability while making reasonable use of layout space. Simultaneously, this configuration allows for a diamond-shaped arrangement of the light-emitting elements, and ensures that the light-emitting elements coupled to a column of drive circuits connected to the data line DA are of the same color.

[0175] like Figures 19 to 24 As shown, in some embodiments, the orthographic projection of the first anode extension ANO21 on the substrate does not overlap with the orthographic projection of the first conductive connection 101 in the first conductive connection structure 31 on the substrate; and / or, the orthographic projection of the first anode extension ANO21 on the substrate does not overlap with the orthographic projection of the second conductive connection 102 in the first conductive connection structure 31 on the substrate.

[0176] The above arrangement allows the first anode body ANO11 to be positioned in the surrounding area of ​​the first conductive connection portion 101 and / or the second conductive connection portion 102 coupled to it, effectively increasing the layout space available to the first anode body ANO11 and reducing the layout difficulty of the display substrate. Simultaneously, the above arrangement enables a diamond-shaped arrangement of the light-emitting elements, and ensures that the light-emitting elements coupled to a column of drive circuits coupled to the data line DA are of the same color.

[0177] like Figures 19 to 24 As shown, in some embodiments, the orthographic projection of the third anode extension ANO23 on the substrate does not overlap with the orthographic projection of the first conductive connection 101 in the third conductive connection structure 33 on the substrate; and / or, the orthographic projection of the third anode extension ANO23 on the substrate does not overlap with the orthographic projection of the second conductive connection 102 in the third conductive connection structure 33 on the substrate.

[0178] The above arrangement allows the third anode main body ANO13 to be positioned in the surrounding area of ​​the first conductive connection portion 101 and / or the second conductive connection portion 102 coupled to it, effectively increasing the layout space available to the third anode main body ANO13 and reducing the layout difficulty of the display substrate. Simultaneously, the above arrangement enables a diamond-shaped arrangement of the light-emitting elements, and ensures that the light-emitting elements coupled to a column of drive circuits coupled to the data line DA are of the same color.

[0179] like Figures 19 to 24 As shown, in some embodiments, the orthographic projection of the second anode extension ANO22 on the substrate at least partially overlaps with the orthographic projection of the first conductive connection structure 31 on the substrate.

[0180] For example, the orthographic projection of the second anode extension ANO22 on the substrate at least partially overlaps with the orthographic projection of the second conductive connection 102 included in the first conductive connection structure 31 on the substrate; and / or, the orthographic projection of the second anode extension ANO22 on the substrate at least partially overlaps with the orthographic projection of the third conductive connection 103 included in the first conductive connection structure 31 on the substrate.

[0181] The above arrangement allows the second anode body ANO12 to be positioned near the first conductive connection structure 31, enabling a diamond-shaped arrangement of the light-emitting elements and ensuring that the light-emitting elements coupled to the column of drive circuits coupled to the data line DA are of the same color.

It also enables a diamond-shaped arrangement of the light-emitting elements and ensures that the light-emitting elements coupled to a column of drive circuits connected to the data lines (DA) are of the same color.

[0200] like Figure 26 and Figure 27 As shown, in some embodiments, the third conductive connection portion 103 in the fourth conductive connection structure 34 includes at least a portion extending along the first direction;

[0201] The second conductive connection portion 102 in the fourth conductive connection structure 34 includes a first sub-part 1021 and a second sub-part 1022 coupled together. The first sub-part 1021 extends along the second direction, and the extension direction of the second sub-part 1022 intersects the first direction.

This enables a column of green sub-pixel driving circuits P_G to drive the corresponding green light-emitting element G to the right along the first direction.

[0205] In the display substrate provided in the above embodiments, a column of blue sub-pixel driving circuits P_B can drive the corresponding blue light-emitting elements B to the left and right respectively along the first direction.

[0206] In the display substrate provided in the above embodiments, a column of red sub-pixel driving circuits P_R can drive the corresponding red light-emitting elements R to the left and right respectively along the first direction.

[0207] The above configuration effectively increases the available layout space for the anode pattern, reducing the layout difficulty of the display substrate. It also enables a diamond-shaped arrangement of the light-emitting elements and ensures that the light-emitting elements coupled to a column of drive circuits connected to the data lines (DA) are of the same color.

[0208] like Figure 20 and Figure 32 As shown, in some embodiments, the second conductive connection portion 102 in the first conductive connection structure 31 and the second conductive connection portion 102 in the third conductive connection structure 33 extend in the same direction; the second conductive connection portion 102 in the second conductive connection structure 32 and the second conductive connection portion 102 in the fourth conductive connection structure 34 extend in the same direction.

[0210] This invention also provides a display substrate, comprising: a substrate and a plurality of sub-pixels and a plurality of data lines disposed on the substrate, wherein the sub-pixels include a sub-pixel driving circuit and a light-emitting element coupled to each other;

[0211] The plurality of sub-pixels include a plurality of sub-pixel driving circuits divided into a plurality of driving circuit columns. Each driving circuit column includes a plurality of the sub-pixel driving circuits arranged along a first direction. The light-emitting elements coupled to each sub-pixel driving circuit belonging to the same driving circuit column have the same light-emitting color. The data line is coupled to each sub-pixel driving circuit in the corresponding driving circuit column.

[0212] The multi-column drive circuit column includes multiple first drive circuit columns and multiple second drive circuit columns, wherein the first drive circuit columns and the second drive circuit columns are alternately arranged along a second direction, and the second direction intersects with the first direction;

[0213] The light-emitting elements coupled to the first driving circuit column are arranged along the first direction to form a first light-emitting element column; the light-emitting elements coupled to the second driving circuit column are arranged along the first direction to form a second light-emitting element column.

[0214] The driving transistor in the sub-pixel driving circuit includes an active pattern, and the light-emitting element includes an anode pattern. The anode pattern includes a coupled anode body and an anode extension. In the same column of light-emitting elements, the orthographic projection of the anode body on the substrate does not overlap with the orthographic projection of the active pattern of the driving transistor in the sub-pixel driving circuit coupled to it on the substrate.

[0215] For example, the orthographic projection of the anode body of the light-emitting element on the substrate does not overlap with the orthographic projection of the sub-pixel driving circuit (including the transistor portion of the circuit, such as the active layer in the transistor) driving the light-emitting element on the substrate.

[0216] For example, the orthographic projection of the first light-emitting element on the substrate at least partially overlaps with the orthographic projection of the second driving circuit on the substrate; the orthographic projection of the second light-emitting element on the substrate at least partially overlaps with the orthographic projection of the first driving circuit on the substrate.

[0217] By setting the sub-pixel driving circuit and the anode pattern to be staggered in the column direction, the data lines coupled to the sub-pixel driving circuit in the same column can only write the data signal corresponding to the pixel of the same color, thereby achieving the effect of reducing power consumption. In addition, in the sub-pixels of the same color, the distance between the light-emitting element and the sub-pixel driving circuit is roughly the same, resulting in more uniform light emission.

[0218] This invention also provides a display device, including the display substrate provided in the above embodiments.

[0219] It should be noted that the display device can be any product or component with display function, such as a television, monitor, digital photo frame, mobile phone, or tablet computer. The display device also includes flexible circuit boards, printed circuit boards, and backplanes.

[0220] In the display substrate provided in the above embodiments, the light-emitting elements included in the plurality of sub-pixels are arranged in a diamond-shaped repeating unit. Simultaneously, the plurality of sub-pixel driving circuits included in the plurality of sub-pixels are divided into multiple columns of driving circuits. Each column of driving circuits includes multiple sub-pixel driving circuits arranged along a first direction. The light-emitting elements coupled to each sub-pixel driving circuit in the same column of driving circuits have the same light emission color. The data line is coupled to each sub-pixel driving circuit in the corresponding column of driving circuits. Since the light-emitting elements coupled to each sub-pixel driving circuit in the corresponding column of driving circuits have the same light emission color, when the shift register unit scans the sub-pixels line by line, that is, when the data line sequentially provides data signals to a column of sub-pixels, the voltage variation range of the data signal transmitted by the data line is very small or constant. Thus, the driving chip does not need to repeatedly switch and charge the data signal to ensure that the data line can provide the corresponding data range of data signals to its coupled sub-pixels, thereby effectively reducing the power consumption of the driving chip and the overall power consumption of the display product. Therefore, in the display substrate provided in the above embodiments, by implementing a diamond arrangement, the technical effect of reducing the power consumption of the driver chip and reducing the overall power consumption of the display product is achieved.

[0221] The display device provided in the embodiments of the present invention, when including the above-described display substrate, also has the above-described beneficial effects, which will not be repeated here.

[0222] It should be noted that the signal line extending along the X direction means that the signal line includes a main part and a secondary part connected to the main part. The main part is a line, line segment, or strip-shaped body. The main part extends along the X direction, and the length of the main part extending along the X direction is greater than the length of the secondary part extending in other directions.

[0223] It should be noted that, in the embodiments of the present invention, "same layer" can refer to film layers located on the same structural layer. Alternatively, for example, film layers located on the same layer can be layer structures formed by using the same film deposition process to form a specific pattern, and then patterning the film layer using the same photomask through a single patterning process. Depending on the specific pattern, the single patterning process may include multiple exposure, development, or etching processes, and the specific pattern in the formed layer structure can be continuous or discontinuous. These specific patterns may also be at different heights or have different thicknesses.

Each embodiment focuses on describing the differences from other embodiments. In particular, the method embodiments are basically similar to the product embodiments, so the description is relatively simple, and the relevant parts can be referred to the description of the product embodiments.

[0228] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0229] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
