Description

Technical Field

[0001] Embodiments of the present disclosure relate to a display substrate and a display device. Background Art

[0002] Active matrix organic light emitting diode display devices (AMOLED) have become the research hotspot and technology development direction of major manufacturers due to their advantages such as wide color gamut, high contrast, thin and light design, self-luminescence, bright colors, low power consumption and wide viewing angle. At present, active matrix organic light emitting diode display devices have been widely used in various electronic products, ranging from small electronic products such as smart bracelets, smart watches, smart phones, tablet computers, etc. to large electronic products such as laptops, desktop computers, and televisions. Therefore, the market demand for active matrix organic light emitting diode display devices is also growing.

[0003] The light-emitting principle of the active matrix organic light-emitting diode display device is as follows: the display substrate of the active matrix organic light-emitting diode display device is formed with an anode, a cathode and an organic light-emitting layer; when light-emitting display is performed, electrons and holes are injected from the cathode and the anode into the electron transport layer and the hole transport layer respectively, and then the electrons and holes migrate from the electron transport layer and the hole transport layer to the organic light-emitting layer respectively, and meet in the organic light-emitting layer to form excitons and emit visible light. Utility Model Content

[0004] The embodiment of the present disclosure provides a display substrate and a display device. Since the adjacent first and second vertices of the first virtual quadrilateral region are respectively provided with a first spacer and a second spacer, and two first color sub-pixels are provided at the two corners where the first and second vertices are located, therefore, for the two first color sub-pixels provided at the two corners where the first and second vertices are located, one of the two first color sub-pixels is provided with a first spacer in the first direction, and the other is provided with a second spacer in the second direction. That is to say, one of the two first color sub-pixels is adjacent to the first spacer in the first direction, and the other is adjacent to the second spacer in the second direction. When the FMM and the display substrate used to form the first color sub-pixel are displaced in the first direction or the second direction, and one of the first spacers and the second spacer of the adjacent first and second vertices of the first virtual quadrilateral region cannot effectively support the FMM, due to the small displacement of the dislocation in the other direction, the other of the first spacer and the second spacer can also effectively support the FMM, thereby preventing the FMM from scratching the film layer structure of multiple sub-pixels on the display substrate, such as the organic light-emitting layer, thereby avoiding various defects.

[0045] 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, rather than 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.

[0046] 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 words "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. The words "include" or "comprise" and similar words 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.

[0047] The features such as "parallel", "perpendicular" and "same" used in the embodiments of the present disclosure include the features such as "parallel", "perpendicular" and "same" in a strict sense, as well as the cases where "approximately parallel", "approximately perpendicular" and "approximately the same" contain certain errors, taking into account the errors associated with the measurement and the measurement of specific quantities (for example, the limitations of the measurement system), and are expressed as within the acceptable deviation range for a specific value determined by ordinary technicians in this field. For example, "approximately" can mean within one or more standard deviations, or within 10% or 5% of the value. When the number of a component is not specifically indicated in the following of the embodiments of the present disclosure, it means that the component can be one or more, or can be understood as at least one. "At least one" refers to one or more, and "multiple" refers to at least two. The "same layer" in the embodiments of the present disclosure refers to the relationship between multiple film layers formed by the same material after the same step (for example, a one-step patterning process). The "same layer" here does not always mean that the thickness of multiple film layers is the same or the height of multiple film layers in the cross-sectional view is the same.

[0048] In the manufacturing process of active matrix organic light emitting diode display devices, the organic light emitting layer is usually formed by an evaporation process using an extremely fine metal mask (FMM); in this process, a spacer (PS) needs to be set on the display substrate to support the FMM to prevent the FMM from scratching the organic light emitting layer on the display substrate, thereby causing various defects. Therefore, the morphology, quantity, position, density and other parameters of the spacer need to be comprehensively considered in combination with the process requirements and the characteristics of different products, and the design should be balanced.

[0049] The inventor of this application noticed that in the actual process, the relative position of the FMM and the display substrate is prone to shifting, and the spacers are usually placed in the same environment, resulting in insufficient margins of the FMM of the R / G / B sub-pixels in the X direction or Y direction. When shifting in the X direction or Y direction occurs, a large number or even all of the spacers cannot effectively support the FMM, making it easy for the FMM to scratch the organic light-emitting layer in the pixel opening, resulting in various defects. It should be noted that the above-mentioned same environment refers to the same type, quantity and arrangement of the sub-pixels around the positions where the different spacers are located.

[0050] In this regard, the embodiment of the present disclosure provides a display substrate, which includes: a base substrate; a plurality of sub-pixels, which are located on the base substrate; and a plurality of spacers, each spacer being located in the spacing area between adjacent sub-pixels. The plurality of sub-pixels include a first color sub-pixel, a second color sub-pixel and a third color sub-pixel; the display substrate includes a first virtual quadrilateral area, the plurality of spacers include a first spacer and a second spacer, a first spacer and a second spacer are respectively located at the first vertex and the second vertex of the first virtual quadrilateral area, the first vertex and the second vertex are adjacent, and two first color sub-pixels are located at the two corners where the first vertex and the second vertex are located. Since the adjacent first and second vertices of the first virtual quadrilateral area are respectively provided with the first spacer and the second spacer, and the two corners where the first and second vertices are located are provided with two first color sub-pixels, therefore, for the two first color sub-pixels provided at the two corners where the first and second vertices are located, one of the two first color sub-pixels is provided with the first spacer in the first direction, and the other is provided with the second spacer in the second direction. That is, one of the two first color sub-pixels is adjacent to the first spacer in the first direction, and the other is adjacent to the second spacer in the second direction. When the FMM and the display substrate used to form the first color sub-pixel are displaced in the first direction or the second direction, and one of the first spacer and the second spacer at the adjacent first vertex and second vertex of the first virtual quadrilateral area cannot effectively support the FMM, since the displacement of the dislocation in the other direction is smaller, the other of the first spacer and the second spacer can still effectively support the FMM, thereby preventing the FMM from scratching the film structure of multiple sub-pixels on the display substrate, such as the organic light-emitting layer, and thus avoiding various defects.

[0051] The embodiment of the present disclosure also provides a display device, including the above-mentioned display substrate. Therefore, the display device can also prevent the FMM from scratching multiple sub-pixels on the display substrate, thereby avoiding various defects, thereby having a higher product yield and higher display quality.

[0052] The display substrate and the display device provided by the embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0053] Figure 1 FIG. 1 is a schematic plan view of a display substrate provided by an embodiment of the present disclosure. Figure 1As shown, the display substrate 100 includes: a base substrate 110; a plurality of sub-pixels 120, which are located on the base substrate 110; and a plurality of spacers 130, each spacer 130 being located in the spacing area between adjacent sub-pixels 120. The plurality of sub-pixels 120 include a first color sub-pixel 120A, a second color sub-pixel 120B, and a third color sub-pixel 120C. The first color sub-pixel 120A is configured to emit light of a first color, the second color sub-pixel 120B is configured to emit light of a second color, and the third color sub-pixel 120C is configured to emit light of a third color. When forming the organic light-emitting layer of each sub-pixel 120, the plurality of spacers 130 can be used to support an extremely fine metal mask; in addition, the organic light-emitting layers of the first color sub-pixel 120A, the second color sub-pixel 120B, and the third color sub-pixel 120C are usually formed using different extremely fine metal masks.

[0054] For example, the first color may be red, and its wavelength may be in the range of 620-750 nanometers, the second color may be green, and its wavelength may be in the range of 495-570 nanometers, and the third color may be blue, and its wavelength may be in the range of 450-495 nanometers.

[0055] like Figure 1 As shown, the display substrate 100 includes a first virtual quadrilateral region A, a plurality of spacers 130 include a first spacer 131 and a second spacer 132, a first spacer 131 and a second spacer 132 are respectively located at a first vertex P11 and a second vertex P12 of the first virtual quadrilateral region A; the first vertex P11 and the second vertex P12 are adjacent, or the first vertex P11 and the second vertex P12 are located at two ends of the same edge of the first virtual quadrilateral region A. Two first color sub-pixels 120A are located at two corners where the first vertex P11 and the second vertex P12 of the first virtual quadrilateral region A are located.

[0056] In the display substrate provided by the embodiment of the present disclosure, since the adjacent first and second vertices of the first virtual quadrilateral region are respectively provided with the first spacer and the second spacer, and the two corners where the first and second vertices are located are provided with two first color sub-pixels, therefore, for the two first color sub-pixels provided at the two corners where the first and second vertices are located, one of the two first color sub-pixels is provided with the first spacer in the first direction, and the other is provided with the second spacer in the second direction. That is to say, one of the two first color sub-pixels is adjacent to the first spacer in the first direction, and the other is adjacent to the second spacer in the second direction. When the FMM used to form the first color sub-pixel and the display substrate are displaced in the first direction or the second direction, and one of the first spacer and the second spacer of the adjacent first and second vertices of the first virtual quadrilateral region cannot effectively support the FMM, due to the small displacement of the dislocation in the other direction, the other of the first spacer and the second spacer can also effectively support the FMM, thereby preventing the FMM from scratching the film structure of multiple sub-pixels on the display substrate, such as the organic light-emitting layer, and thus avoiding various defects.

[0057] In some examples, such as Figure 1 As shown, the plurality of sub-pixels 120 include a first pixel group 141 and a second pixel group 142; the first pixel group 141 includes a first color sub-pixel 120A and a third color sub-pixel 120C arranged along a first direction and two second color sub-pixels 120B arranged along a second direction, and the second pixel group 142 includes two second color sub-pixels 120B arranged along the first direction and a first color sub-pixel 120A and a third color sub-pixel 120C arranged along the second direction. It can be seen that the types and quantities of the sub-pixels in the first pixel group 141 and the second pixel group 142 are the same, but the arrangement methods are different.

[0058] In some examples, such as Figure 1 As shown, the first spacer 131 is located in the spaced area surrounded by the first color sub-pixel 120A, the second color sub-pixel 120B and the third color sub-pixel 120C in the first pixel group 141, and the second spacer 132 is located in the spaced area surrounded by the first color sub-pixel 120A, the second color sub-pixel 120B and the third color sub-pixel 120C in the second pixel group 142. In other words, the first spacer 131 and the second spacer 132 are located in different environments.

[0059] In the display substrate provided in this example, for the first color sub-pixel in the first pixel group, the first spacer is located on one side of the first color sub-pixel in the first direction, and for the first color sub-pixel in the second pixel group, the second spacer is located on one side of the first color sub-pixel in the second direction. When the FMM and the display substrate used to form the first color sub-pixel are displaced in the first direction or the second direction, and one of the first spacer and the second spacer cannot effectively support the FMM, since the displacement of the dislocation in the other direction is smaller, the other of the first spacer and the second spacer can still effectively support the FMM, thereby preventing the FMM from scratching the film layer structure of multiple sub-pixels on the display substrate, thereby avoiding various defects.

[0060] Similarly, for the third color sub-pixel in the first pixel group, the first spacer is located on one side of the third color sub-pixel in the first direction, and for the third color sub-pixel in the second pixel group, the second spacer is located on one side of the third color sub-pixel in the second direction. When the FMM and the display substrate used to form the third color sub-pixel are displaced in the first direction or the second direction, and one of the first spacer and the second spacer cannot effectively support the FMM, since the displacement of the dislocation in the other direction is smaller, the other of the first spacer and the second spacer can still effectively support the FMM, thereby preventing the FMM from scratching the film layer structure of multiple sub-pixels on the display substrate, thereby avoiding various defects.

[0061] Similarly, for the second color sub-pixel in the first pixel group, the first spacer is located on one side of the second color sub-pixel in the second direction, and for the second color sub-pixel in the second pixel group, the second spacer is located on one side of the second color sub-pixel in the first direction. When the FMM and the display substrate used to form the second color sub-pixel are displaced in the first direction or the second direction, and one of the first spacer and the second spacer cannot effectively support the FMM, since the displacement of the dislocation in the other direction is smaller, the other of the first spacer and the second spacer can still effectively support the FMM, thereby preventing the FMM from scratching the film structure of multiple sub-pixels on the display substrate, thereby avoiding various defects.

[0062] In some examples, such as Figure 1As shown, the plurality of spacers 130 include a third spacer 133 and a fourth spacer 134, the third spacer 133 and the fourth spacer 134 are respectively located at the third vertex P13 and the fourth vertex P14 of the first virtual quadrilateral area A, the third vertex P13 and the fourth vertex P14 are adjacent, or the third vertex P13 and the fourth vertex P14 are located at two end points of an edge of the first virtual quadrilateral area A. It should be noted that the third vertex P13 and the fourth vertex P14 are different from the first vertex P11 and the second vertex P12.

[0063] In some examples, such as Figure 1 As shown, two first color sub-pixels 120A are located at two corners where the third vertex P13 and the fourth vertex P14 of the first virtual quadrilateral region A are located. Since the adjacent first vertex and the second vertex of the first virtual quadrilateral region are respectively provided with the first spacer and the second spacer, the adjacent third vertex and the fourth vertex are respectively provided with the third spacer and the fourth spacer, and the four corners where the first vertex, the second vertex, the third vertex and the fourth vertex of the first virtual quadrilateral region are located are provided with four first color sub-pixels, therefore, for the four first color sub-pixels provided at the four corners where the first vertex, the second vertex, the third vertex and the fourth vertex are located, the first of the four first color sub-pixels is provided with the first spacer on the first side in the first direction, the second of the four first color sub-pixels is provided with the third spacer on the second side in the first direction, the third of the four first color sub-pixels is provided with the second spacer on the third side in the second direction, and the fourth of the four first color sub-pixels is provided with the fourth spacer on the fourth side in the second direction. When the FMM and the display substrate used to form the first color sub-pixel are displaced toward the first side in the first direction, and the first spacer cannot effectively support the FMM, the second spacer, the third spacer, and the fourth spacer can still effectively support the FMM, thereby preventing the FMM from scratching the film structure of multiple sub-pixels on the display substrate, such as the organic light-emitting layer, and thus avoiding various defects. Similarly, when the displacement occurs in other directions, the FMM can also be prevented from scratching the film structure of multiple sub-pixels on the display substrate, which will not be repeated here.

[0064] In some examples, such as Figure 1 As shown, the first vertex P11 and the fourth vertex P14 of the first virtual quadrilateral area A are adjacent.

[0065] In some examples, such as Figure 1As shown, the plurality of sub-pixels 120 include a third pixel group 143 and a fourth pixel group 144, the arrangement of the sub-pixels 120 in the fourth pixel group 144 is mirror-symmetrical with the arrangement of the sub-pixels 120 in the second pixel group 142 with respect to a first virtual straight line extending along the first direction, and the arrangement of the sub-pixels 120 in the third pixel group 143 is mirror-symmetrical with the arrangement of the sub-pixels 120 in the first pixel group 141 with respect to a second virtual straight line extending along the second direction. That is, the third pixel group 143 includes the third color sub-pixel 120C and the first color sub-pixel 120A arranged along the first direction and two second color sub-pixels 120B arranged along the second direction, and the fourth pixel group 144 includes the two second color sub-pixels 120B arranged along the first direction and the third color sub-pixel 120C and the first color sub-pixel 120A arranged along the second direction.

[0066] In some examples, such as Figure 1 As shown, the third spacer 133 is located in the spacing area surrounded by the first color sub-pixel 120A, the second color sub-pixel 120B and the third color sub-pixel 120C in the third pixel group 143, and the fourth spacer 134 is located in the spacing area surrounded by the first color sub-pixel 120A, the second color sub-pixel 120B and the third color sub-pixel 120C in the fourth pixel group 144.

[0067] In the display substrate provided in this example, since the first spacer, the second spacer, the third spacer and the fourth spacer are respectively located in the first pixel group, the second pixel group, the third pixel group and the fourth pixel group, for the multiple first color sub-pixels on the display substrate, there are four positions where spacers are provided, namely: some first color sub-pixels are provided with spacers on the first side in the first direction, some first color sub-pixels are provided with spacers on the second side in the second direction, some first color sub-pixels are provided with spacers on the third side in the second direction, and some first color sub-pixels are provided with spacers on the fourth side in the second direction. Therefore, when the FMM used to form the first color sub-pixels and the display substrate are displaced in one position, and some spacers cannot effectively support the FMM, the spacers in other positions can still effectively support the FMM, thereby preventing the FMM from scratching the film structure of the multiple sub-pixels on the display substrate, thereby avoiding various defects.

[0068] In some examples, such as Figure 1 As shown, the length of the virtual side where the first vertex P11 and the second vertex P12 of the first virtual quadrilateral area A are located is greater than the size of the N first color sub-pixels 120A in the extension direction of the virtual side, and the value of N is greater than or equal to 2. In other words, the range or size of the first virtual quadrilateral area can be set according to actual needs.

[0069] In some examples, such as Figure 1 As shown, the shape of the first virtual quadrilateral region A is a rectangle. Therefore, the line between the first spacer 131 and the first color sub-pixel 120A located near the first vertex P11 of the first virtual quadrilateral region A and the line between the second spacer 132 and the first color sub-pixel 120A located near the second vertex P12 of the first virtual quadrilateral region A are perpendicular to each other. Of course, the embodiments of the present disclosure include but are not limited to this, and the shape of the first virtual quadrilateral region may also be other shapes.

[0070] In some examples, such as Figure 1 As shown, the display substrate 100 includes a second virtual quadrilateral region B, a first spacer 131 and a second spacer 132 are respectively located at the fifth vertex P21 and the sixth vertex P22 of the second virtual quadrilateral region B, and the fifth vertex P21 and the sixth vertex P22 are adjacent to each other or located at two end points of the same edge of the second virtual quadrilateral region B. Two second color sub-pixels 120B are located at two corners of the second virtual quadrilateral region B where the fifth vertex P21 and the sixth vertex P22 are located.

[0071] In the display substrate provided by the embodiment of the present disclosure, since the adjacent fifth and sixth vertices of the second virtual quadrilateral region are respectively provided with the first spacer and the second spacer, and the two corners where the fifth and sixth vertices are located are provided with two second color sub-pixels, therefore, for the two second color sub-pixels provided at the two corners where the fifth and sixth vertices are located, one of the two second color sub-pixels is provided with the first spacer in the first direction, and the other is provided with the second spacer in the second direction. That is to say, one of the two second color sub-pixels is adjacent to the first spacer in the first direction, and the other is adjacent to the second spacer in the second direction. When the FMM and the display substrate used to form the second color sub-pixel are displaced in the first direction or the second direction, and one of the first spacer and the second spacer of the adjacent fifth and sixth vertices of the second virtual quadrilateral region cannot effectively support the FMM, due to the small displacement of the dislocation in the other direction, the other of the first spacer and the second spacer can also effectively support the FMM, thereby preventing the FMM from scratching the film structure of multiple sub-pixels on the display substrate, such as the organic light-emitting layer, thereby avoiding various defects.

[0072] In some examples, such as Figure 1As shown, the shape of the second virtual quadrilateral region B is a rectangle. Therefore, the line between the first spacer 131 and the second color sub-pixel 120B located near the fifth vertex P21 of the second virtual quadrilateral region B and the line between the second spacer 132 and the second color sub-pixel 120B located near the sixth vertex P22 of the second virtual quadrilateral region B are perpendicular to each other. Of course, the embodiments of the present disclosure include but are not limited to this, and the shape of the second virtual quadrilateral region may also be other shapes.

[0073] In some examples, such as Figure 1 As shown, the length of the virtual side where the fifth vertex P21 and the sixth vertex P22 of the second virtual quadrilateral area B are located is greater than the size of the N second color sub-pixels 120A in the extension direction of the virtual side, and the value of N is greater than or equal to 2. In other words, the range or size of the second virtual quadrilateral area can be set according to actual needs.

[0074] In some examples, such as Figure 1 As shown, the display substrate 100 includes a third virtual quadrilateral area C, a first spacer 131 and a second spacer 132 are respectively located at the seventh vertex P31 and the eighth vertex P32 of the third virtual quadrilateral area C, and the seventh vertex P31 and the eighth vertex P32 are adjacent to each other, or are two endpoints on the same virtual side of the third virtual quadrilateral area C. Two third color sub-pixels 120C are located at two corners of the third virtual quadrilateral area C where the seventh vertex P31 and the eighth vertex P32 are located. It should be noted that Figure 1 The rectangular blocks shown in A, B, C, and D are not actual structures, but schematically illustrate the range of the above-mentioned various virtual quadrilateral areas; and the edges of the above-mentioned various virtual quadrilateral areas are defined by the above-mentioned vertices or the centers of the spacers, not by the above-mentioned rectangular blocks shown in A, B, C, and D.

[0075] In the display substrate provided by the embodiment of the present disclosure, since the adjacent seventh and eighth vertices of the third virtual quadrilateral region are respectively provided with the first spacer and the second spacer, and the two corners where the seventh and eighth vertices are located are provided with two second color sub-pixels, therefore, for the two third color sub-pixels provided at the two corners where the seventh and eighth vertices are located, one of the two third color sub-pixels is provided with the first spacer in the first direction, and the other is provided with the second spacer in the second direction. That is to say, one of the two third color sub-pixels is adjacent to the first spacer in the first direction, and the other is adjacent to the second spacer in the second direction. When the FMM used to form the third color sub-pixel and the display substrate are displaced in the first direction or the second direction, and one of the first spacer and the second spacer of the adjacent seventh and eighth vertices of the third virtual quadrilateral region cannot effectively support the FMM, due to the small displacement of the dislocation in the other direction, the other of the first spacer and the second spacer can also effectively support the FMM, thereby preventing the FMM from scratching the film structure of multiple sub-pixels on the display substrate, such as the organic light-emitting layer, thereby avoiding various defects.

[0076] In some examples, such as Figure 1 As shown, the shape of the third virtual quadrilateral region C is a rectangle. Therefore, the line between the first spacer 131 located near the seventh vertex P31 of the third virtual quadrilateral region C and the third color sub-pixel 120C is perpendicular to the line between the second spacer 132 located near the eighth vertex P32 of the third virtual quadrilateral region C and the third color sub-pixel 120C. Of course, the embodiments of the present disclosure include but are not limited to this, and the shape of the third virtual quadrilateral region may also be other shapes.

[0077] In some examples, such as Figure 1 As shown, the length of the virtual side where the seventh vertex P31 and the eighth vertex P32 of the third virtual quadrilateral area C are located is greater than the size of the N third color sub-pixels 120C in the extension direction of the virtual side, and the value of N is greater than or equal to 2. In other words, the range or size of the third virtual quadrilateral area can be set according to actual needs.

[0078] In some examples, such as Figure 1 As shown, the display substrate 100 may further include a fourth virtual quadrilateral region D, a first spacer 131 and a second spacer 132 are respectively located at the ninth vertex P41 and the tenth vertex P42 of the fourth virtual quadrilateral region D, and the ninth vertex P41 and the tenth vertex P42 are adjacent to each other, or are two end points on the same virtual side of the fourth virtual quadrilateral region D. The two second color sub-pixels 120B are located at the two corners where the ninth vertex P41 and the tenth vertex P42 of the third virtual quadrilateral region C are located. It should be noted that Figure 1 The rectangular blocks shown in A, B, C, and D are not actual structures, but schematically illustrate the range of the above-mentioned various virtual quadrilateral areas; and the edges of the above-mentioned various virtual quadrilateral areas are defined by the above-mentioned vertices or the centers of the spacers, not by the above-mentioned rectangular blocks shown in A, B, C, and D.

[0079] In the display substrate provided by the embodiment of the present disclosure, since the adjacent ninth and tenth vertices of the fourth virtual quadrilateral region are respectively provided with the first spacer and the second spacer, and the two corners where the ninth and tenth vertices are located are provided with two second color sub-pixels, therefore, for the two second color sub-pixels provided at the two corners where the ninth and tenth vertices are located, one of the two second color sub-pixels is provided with the first spacer in the first direction, and the other is provided with the second spacer in the second direction. That is to say, one of the two second color sub-pixels is adjacent to the first spacer in the first direction, and the other is adjacent to the second spacer in the second direction. When the FMM and the display substrate used to form the third color sub-pixel are displaced in the first direction or the second direction, and one of the first spacer and the second spacer of the adjacent ninth and tenth vertices of the fourth virtual quadrilateral region cannot effectively support the FMM, due to the small displacement of the dislocation in the other direction, the other of the first spacer and the second spacer can also effectively support the FMM, thereby preventing the FMM from scratching the film structure of multiple sub-pixels on the display substrate, such as the organic light-emitting layer, thereby avoiding various defects.

[0080] In some examples, such as Figure 1 As shown, the shape of the fourth virtual quadrilateral region D is a rectangle. Therefore, the line between the first spacer 131 and the second color sub-pixel 120B located near the ninth vertex P41 of the fourth virtual quadrilateral region D and the line between the second spacer 132 and the second color sub-pixel 120B located near the tenth vertex P42 of the fourth virtual quadrilateral region D are perpendicular to each other. Of course, the embodiments of the present disclosure include but are not limited to this, and the shape of the fourth virtual quadrilateral region may also be other shapes.

[0081] In some examples, such as Figure 1 As shown, the length of the virtual side where the ninth vertex P41 and the tenth vertex P42 of the fourth virtual quadrilateral area D are located is greater than the size of the N second color sub-pixels 120B in the extension direction of the virtual side, and the value of N is greater than or equal to 2. In other words, the range or size of the fourth virtual quadrilateral area can be set according to actual needs.

[0082] In some examples, such as Figure 1As shown, the first virtual quadrilateral area A, the second virtual quadrilateral area B, the third virtual quadrilateral area C and the fourth virtual quadrilateral area D may constitute a larger virtual quadrilateral area.

[0083] In some examples, such as Figure 1 As shown, the first virtual quadrilateral area A and the second virtual quadrilateral area B share an edge; the second virtual quadrilateral area B and the third virtual quadrilateral area C share an edge; the third virtual quadrilateral area C and the fourth virtual quadrilateral area D share an edge.

[0084] In some examples, such as Figure 1 As shown, each spacer 130 is disposed adjacent to four sub-pixels 120, and no other sub-pixels exist between the spacer 130 and the adjacent sub-pixels 120. Thus, the spacer can be disposed in the area surrounded by the four sub-pixels, thereby fully utilizing the space on the display substrate.

[0085] In some examples, such as Figure 1 As shown, each spacer 130 is located between corners of four adjacent sub-pixels 120 , rather than between edges of adjacent sub-pixels.

[0086] In some examples, such as Figure 1 As shown, the display substrate 100 also includes a pixel partition structure 150, which includes a first pixel partition structure 151 and a second pixel partition structure 152; the first pixel partition structure 151 is located between adjacent first color sub-pixels 120A and second color sub-pixels 120B; the second pixel partition structure 152 is located between adjacent third color sub-pixels 120C and second color sub-pixels 120B, and each spacer 130 is located in the area between the two first pixel partition structures 151 and the two second pixel partition structures 152.

[0087] In the display substrate provided in this example, the display substrate 100 may adopt a tandem light-emitting technology (Tandem), that is, the light-emitting layer 122 of each sub-pixel 120 may include a plurality of light-emitting sub-layers and a charge generation layer between the light-emitting sub-layers. As a result, the display substrate 100 may have a higher luminous brightness and service life. When the display substrate 100 adopts a tandem light-emitting technology, the thickness of the light-emitting layer is relatively large and the height is relatively high. On the other hand, the pixel partition structure 150 may isolate the charge generation layer of adjacent sub-pixels 120 to prevent crosstalk. Each spacer 130 is located in the area between the two first pixel partition structures 151 and the two second pixel partition structures 152, the size of the spacer is further limited, and the thickness of the light-emitting layer is still relatively large, so when the FMM is not sufficiently supported, it is easier to scratch the light-emitting layer 122, causing various defects. In this case, by adopting the design of the spacer provided in the embodiment of the present disclosure, the display substrate can still avoid the FMM scratching the film layer structure of multiple sub-pixels on the display substrate, such as the organic light-emitting layer, while adopting the stacked light-emitting technology, thereby avoiding various defects, thereby having a higher display performance and a higher yield.

[0088] In some examples, such as Figure 1 As shown, the display substrate 100 includes a base substrate 110, a plurality of sub-pixels 120 and a plurality of spacers 130; the plurality of sub-pixels 120 are located on the base substrate 110 and include a first color sub-pixel 120A, a second color sub-pixel 120B and a third color sub-pixel 120C; each spacer 130 is located in the spacing area between adjacent sub-pixels 120. The plurality of sub-pixels 120 include a plurality of first sub-pixel rows 161 and a plurality of first sub-pixel columns 171, each first sub-pixel row 161 includes a plurality of first color sub-pixels 120A and a plurality of third color sub-pixels 120C alternately arranged along a first direction, each first sub-pixel column 171 includes a plurality of first color sub-pixels 120A and a plurality of third color sub-pixels 120C alternately arranged along a second direction, the plurality of first sub-pixel rows 161 are arranged along the second direction, the plurality of first sub-pixel columns 171 are arranged along the first direction, and the first direction and the second direction intersect. The plurality of spacers 130 include a first spacer 131 and a second spacer 132.

[0089] like Figure 1 As shown, a plurality of first sub-pixel rows 161 include a plurality of first pixel spacer rows 1615, each first pixel spacer row 1615 includes a first spacer 131, and is located between the first color sub-pixel 120A and the third color sub-pixel 120C adjacent to each other in the first direction; a plurality of first sub-pixel columns 171 include a plurality of first pixel spacer columns 1715, each first pixel spacer column 1715 includes a second spacer 132, and is located between the first color sub-pixel 120A and the third color sub-pixel 120C adjacent to each other in the second direction.

[0090] In the display substrate provided by the embodiment of the present disclosure, since each first pixel spacer row 1615 includes a first spacer 131, which is located between the first color sub-pixel 120A and the third color sub-pixel 120C adjacent in the first direction, and each first pixel spacer column 1715 includes a second spacer 132, which is located between the first color sub-pixel 120A and the third color sub-pixel 120C adjacent in the second direction, for the first color sub-pixel, part of the first color sub-pixel is provided with the first spacer in the first direction, and part of the first color sub-pixel is provided with the second spacer in the second direction. When the FMM used to form the first color sub-pixel and the display substrate are displaced in the first direction or the second direction, and one of the first spacer and the second spacer cannot effectively support the FMM, since the displacement of the dislocation in the other direction is small, the other of the first spacer and the second spacer can still effectively support the FMM, thereby preventing the FMM from scratching the film structure of multiple sub-pixels on the display substrate, such as the organic light-emitting layer, and thus avoiding various defects.

[0091] Similarly, for the third color sub-pixel, some of the third color sub-pixels are provided with a first spacer in the first direction, and some of the third color sub-pixels are provided with a second spacer in the second direction. When the FMM and the display substrate used to form the third color sub-pixel are displaced in the first direction or the second direction, and one of the first spacer and the second spacer cannot effectively support the FMM, since the displacement of the dislocation in the other direction is smaller, the other of the first spacer and the second spacer can still effectively support the FMM, thereby preventing the FMM from scratching the film structure of multiple sub-pixels on the display substrate, such as the organic light-emitting layer, and thus avoiding various defects.

[0092] For example, the first direction is perpendicular to the second direction. Of course, the embodiments of the present disclosure include but are not limited to this, and the first direction and the second direction may not be perpendicular.

[0093] In some examples, such as Figure 1 As shown, in the plurality of first sub-pixel rows 161, the plurality of first pixel spacer rows 1615 are evenly distributed. For example, one first pixel spacer row 1615 is provided for every four first sub-pixel rows 161. Of course, the embodiments of the present disclosure include but are not limited to this.

[0094] In some examples, such as Figure 1 As shown, in the plurality of first sub-pixel columns 171, the plurality of first pixel spacer columns 1715 are evenly distributed. For example, one first pixel spacer column 1715 is provided for every four first sub-pixel columns 171. Of course, the embodiments of the present disclosure include but are not limited to this.

[0095] In some examples, such as Figure 1 As shown, the first spacers 131 in two adjacent first pixel spacer rows 1615 in the second direction are aligned in the second direction, that is, the corresponding first spacers 131 in two adjacent first pixel spacer rows 1615 in the second direction are located on a straight line extending along the second direction.

[0096] In some examples, such as Figure 1 As shown, the second spacers 132 in the first pixel spacer columns 1715 adjacent to each other in the first direction are aligned in the first direction, that is, the corresponding second spacers 132 in the first pixel spacer columns 1715 adjacent to each other in the first direction are located on a straight line extending along the first direction.

[0097] In some examples, such as Figure 1 As shown, the multiple sub-pixels 120 include multiple second sub-pixel rows 162 and multiple second sub-pixel columns 172, each second sub-pixel row 162 includes multiple second color sub-pixels 120B alternately arranged along the first direction, each second sub-pixel column 172 includes multiple second color sub-pixels 120B alternately arranged along the second direction, the multiple second sub-pixel rows 162 are arranged along the second direction, and the multiple second sub-pixel columns 172 are arranged along the first direction.

[0098] In some examples, such as Figure 1 As shown, the plurality of second sub-pixel rows 162 include a plurality of second pixel spacer rows 1625, each second pixel spacer row 1625 includes a second spacer 132, and is located between the second color sub-pixels 120B adjacent to each other in the first direction; the plurality of second sub-pixel columns 172 include a plurality of second pixel spacer columns 1725, each second pixel spacer column 1725 includes a first spacer 131, and is located between the second color sub-pixels 120B adjacent to each other in the second direction.

[0099] In the display substrate provided by the embodiment of the present disclosure, since each second pixel spacer row 1625 includes a second spacer 132, which is located between the second color sub-pixels 120B adjacent in the first direction, and each second pixel spacer column 1725 includes a first spacer 131, which is located between the second color sub-pixels 120B adjacent in the second direction, for the second color sub-pixels, some of the second color sub-pixels are provided with the second spacer in the first direction, and some of the second color sub-pixels are provided with the first spacer in the second direction. When the FMM used to form the second color sub-pixels and the display substrate are displaced in the first direction or the second direction, and one of the first spacer and the second spacer cannot effectively support the FMM, since the displacement of the dislocation in the other direction is small, the other of the first spacer and the second spacer can still effectively support the FMM, thereby preventing the FMM from scratching the film structure of multiple sub-pixels on the display substrate, such as the organic light-emitting layer, and thus avoiding various defects.

[0100] In some examples, such as Figure 1 As shown, a plurality of first sub-pixel rows 161 and a plurality of second sub-pixel rows 162 are alternately arranged in the second direction, and a plurality of first sub-pixel columns 171 and a plurality of second sub-pixel columns 172 are alternately arranged in the first direction.

[0101] In some examples, such as Figure 1 As shown, in the plurality of second sub-pixel rows 162, the plurality of second pixel spacer rows 1625 are evenly distributed. For example, one second pixel spacer row 1625 is provided for every four second sub-pixel rows 162. Of course, the embodiments of the present disclosure include but are not limited to this.

[0102] In some examples, such as Figure 1 As shown, in the plurality of second sub-pixel columns 172, the plurality of second pixel spacer columns 1725 are evenly distributed. For example, one second pixel spacer column 1725 is provided for every four second sub-pixel columns 172. Of course, the embodiments of the present disclosure include but are not limited to this.

[0103] In some examples, such as Figure 1 As shown, the second spacers 132 in two second pixel spacer rows 1625 adjacent in the second direction are aligned in the second direction, that is, the corresponding second spacers 132 in two second pixel spacer rows 1625 adjacent in the second direction are located on a straight line extending along the second direction.

[0104] In some examples, such as Figure 1As shown, the first spacers 131 in the second pixel spacer columns 1725 adjacent to each other in the first direction are aligned in the first direction, that is, the corresponding first spacers 131 in the second pixel spacer columns 1725 adjacent to each other in the first direction are located on a straight line extending along the first direction. Figure 2 FIG. 1 is a schematic plan view of another display substrate provided by an embodiment of the present disclosure. Figure 2 As shown, the display substrate 100 includes: a base substrate 110; a plurality of sub-pixels 120, which are located on the base substrate 110; and a plurality of spacers 130, each spacer 130 being located in the spacing area between adjacent sub-pixels 120. The plurality of sub-pixels 120 include a first color sub-pixel 120A, a second color sub-pixel 120B, and a third color sub-pixel 120C. The first color sub-pixel 120A is configured to emit light of a first color, the second color sub-pixel 120B is configured to emit light of a second color, and the third color sub-pixel 120C is configured to emit light of a third color. When forming the organic light-emitting layer of each sub-pixel 120, the plurality of spacers 130 can be used to support an extremely fine metal mask; in addition, the organic light-emitting layers of the first color sub-pixel 120A, the second color sub-pixel 120B, and the third color sub-pixel 120C are usually formed using different extremely fine metal masks.

[0105] For example, the first color may be red, and its wavelength may be in the range of 620-750 nanometers, the second color may be green, and its wavelength may be in the range of 495-570 nanometers, and the third color may be blue, and its wavelength may be in the range of 450-495 nanometers.

[0106] like Figure 2 As shown, the display substrate 100 includes a first virtual quadrilateral region A, a plurality of spacers 130 include a first spacer 131 and a second spacer 132, a first spacer 131 and a second spacer 132 are respectively located at a first vertex P11 and a second vertex P12 of the first virtual quadrilateral region A; the first vertex P11 and the second vertex P12 are adjacent, or the first vertex P11 and the second vertex P12 are located at two ends of the same edge of the first virtual quadrilateral region A. Two first color sub-pixels 120A are located at two corners where the first vertex P11 and the second vertex P12 of the first virtual quadrilateral region A are located.

[0107] In the display substrate provided by the embodiment of the present disclosure, since the adjacent first and second vertices of the first virtual quadrilateral region are respectively provided with the first spacer and the second spacer, and the two corners where the first and second vertices are located are provided with two first color sub-pixels, therefore, for the two first color sub-pixels provided at the two corners where the first and second vertices are located, one of the two first color sub-pixels is provided with the first spacer in the first direction, and the other is provided with the second spacer in the second direction. That is to say, one of the two first color sub-pixels is adjacent to the first spacer in the first direction, and the other is adjacent to the second spacer in the second direction. When the FMM used to form the first color sub-pixel and the display substrate are displaced in the first direction or the second direction, and one of the first spacer and the second spacer of the adjacent first and second vertices of the first virtual quadrilateral region cannot effectively support the FMM, due to the small displacement of the dislocation in the other direction, the other of the first spacer and the second spacer can also effectively support the FMM, thereby preventing the FMM from scratching the film structure of multiple sub-pixels on the display substrate, such as the organic light-emitting layer, and thus avoiding various defects.

[0108] In some examples, such as Figure 2 As shown, the plurality of sub-pixels 120 include a first pixel group 141 and a second pixel group 142; the first pixel group 141 includes a first color sub-pixel 120A and a third color sub-pixel 120C arranged along a first direction and two second color sub-pixels 120B arranged along a second direction, and the second pixel group 142 includes two second color sub-pixels 120B arranged along the first direction and a first color sub-pixel 120A and a third color sub-pixel 120C arranged along the second direction. It can be seen that the types and quantities of the sub-pixels in the first pixel group 141 and the second pixel group 142 are the same, but the arrangement methods are different.

[0109] In some examples, such as Figure 2 As shown, the first spacer 131 is located in the spaced area surrounded by the first color sub-pixel 120A, the second color sub-pixel 120B and the third color sub-pixel 120C in the first pixel group 141, and the second spacer 132 is located in the spaced area surrounded by the first color sub-pixel 120A, the second color sub-pixel 120B and the third color sub-pixel 120C in the second pixel group 142. In other words, the first spacer 131 and the second spacer 132 are located in different environments.

[0110] In the display substrate provided in this example, for the first color sub-pixel in the first pixel group, the first spacer is located on one side of the first color sub-pixel in the first direction, and for the first color sub-pixel in the second pixel group, the second spacer is located on one side of the first color sub-pixel in the second direction. When the FMM and the display substrate used to form the first color sub-pixel are displaced in the first direction or the second direction, and one of the first spacer and the second spacer cannot effectively support the FMM, since the displacement of the dislocation in the other direction is smaller, the other of the first spacer and the second spacer can still effectively support the FMM, thereby preventing the FMM from scratching the film layer structure of multiple sub-pixels on the display substrate, thereby avoiding various defects.

[0111] Similarly, for the third color sub-pixel in the first pixel group, the first spacer is located on one side of the third color sub-pixel in the first direction, and for the third color sub-pixel in the second pixel group, the second spacer is located on one side of the third color sub-pixel in the second direction. When the FMM and the display substrate used to form the third color sub-pixel are displaced in the first direction or the second direction, and one of the first spacer and the second spacer cannot effectively support the FMM, since the displacement of the dislocation in the other direction is smaller, the other of the first spacer and the second spacer can still effectively support the FMM, thereby preventing the FMM from scratching the film layer structure of multiple sub-pixels on the display substrate, thereby avoiding various defects.

[0112] Similarly, for the second color sub-pixel in the first pixel group, the first spacer is located on one side of the second color sub-pixel in the second direction, and for the second color sub-pixel in the second pixel group, the second spacer is located on one side of the second color sub-pixel in the first direction. When the FMM and the display substrate used to form the second color sub-pixel are displaced in the first direction or the second direction, and one of the first spacer and the second spacer cannot effectively support the FMM, since the displacement of the dislocation in the other direction is smaller, the other of the first spacer and the second spacer can still effectively support the FMM, thereby preventing the FMM from scratching the film structure of multiple sub-pixels on the display substrate, thereby avoiding various defects.

[0113] In some examples, such as Figure 2As shown, the sizes of the first spacer 131 and the second spacer 132 are different. For example, the size of the first spacer 131 is larger than the size of the second spacer 132. As described above, since the environments of the first spacer 131 and the second spacer 132 are different, the space where the first spacer 131 is located is larger, so the size of the first spacer 131 can be set to be larger than the size of the second spacer 132, so that the first spacer 131 makes full use of the spacing area within the first pixel group 141, and the first spacer 131 can support the FMM in a larger range, thereby further reducing the risk of the FMM scratching the film structure of multiple sub-pixels on the display substrate.

[0114] In some examples, such as Figure 2 As shown, the first spacer 131 and the second spacer 132 have different shapes. As described above, since the first spacer 131 and the second spacer 132 are located in different environments, the first spacer 131 and the second spacer 132 can be set to specific shapes according to the environments, thereby making full use of the spacing area in the first pixel group 141 and the second pixel group 142.

[0115] For example, Figure 2 As shown, the shape of the first spacer 131 is rectangular, and the shape of the second spacer 132 is circular. Of course, the embodiments of the present disclosure include but are not limited to this, and the shapes of the first spacer and the second spacer can be set according to actual conditions. It should be noted that the shape of the above-mentioned spacer refers to the plane shape of the spacer, that is, the shape of the positive projection of the spacer on the substrate.

[0116] In some examples, such as Figure 2 As shown, the plurality of spacers 130 include a third spacer 133 and a fourth spacer 134, the third spacer 133 and the fourth spacer 134 are respectively located at the third vertex P13 and the fourth vertex P14 of the first virtual quadrilateral area A, the third vertex P13 and the fourth vertex P14 are adjacent, or the third vertex P13 and the fourth vertex P14 are located at two end points of an edge of the first virtual quadrilateral area A. It should be noted that the third vertex P13 and the fourth vertex P14 are different from the first vertex P11 and the second vertex P12.

[0117] In some examples, such as Figure 2As shown, two first color sub-pixels 120A are located at two corners where the third vertex P13 and the fourth vertex P14 of the first virtual quadrilateral region A are located. Since the adjacent first vertex and the second vertex of the first virtual quadrilateral region are respectively provided with the first spacer and the second spacer, the adjacent third vertex and the fourth vertex are respectively provided with the third spacer and the fourth spacer, and the four corners where the first vertex, the second vertex, the third vertex and the fourth vertex of the first virtual quadrilateral region are located are provided with four first color sub-pixels, therefore, for the four first color sub-pixels provided at the four corners where the first vertex, the second vertex, the third vertex and the fourth vertex are located, the first of the four first color sub-pixels is provided with the first spacer on the first side in the first direction, the second of the four first color sub-pixels is provided with the third spacer on the second side in the first direction, the third of the four first color sub-pixels is provided with the second spacer on the third side in the second direction, and the fourth of the four first color sub-pixels is provided with the fourth spacer on the fourth side in the second direction. When the FMM and the display substrate used to form the first color sub-pixel are displaced toward the first side in the first direction, and the first spacer cannot effectively support the FMM, the second spacer, the third spacer, and the fourth spacer can still effectively support the FMM, thereby preventing the FMM from scratching the film structure of multiple sub-pixels on the display substrate, such as the organic light-emitting layer, and thus avoiding various defects. Similarly, when the displacement occurs in other directions, the FMM can also be prevented from scratching the film structure of multiple sub-pixels on the display substrate, which will not be repeated here.

[0118] In some examples, such as Figure 2 As shown, the plurality of sub-pixels 120 include a third pixel group 143 and a fourth pixel group 144, the arrangement of the sub-pixels 120 in the fourth pixel group 144 is mirror-symmetrical with the arrangement of the sub-pixels 120 in the second pixel group 142 with respect to a first virtual straight line extending along the first direction, and the arrangement of the sub-pixels 120 in the third pixel group 143 is mirror-symmetrical with the arrangement of the sub-pixels 120 in the first pixel group 141 with respect to a second virtual straight line extending along the second direction. That is, the third pixel group 143 includes the third color sub-pixel 120C and the first color sub-pixel 120A arranged along the first direction and two second color sub-pixels 120B arranged along the second direction, and the fourth pixel group 144 includes the two second color sub-pixels 120B arranged along the first direction and the third color sub-pixel 120C and the first color sub-pixel 120A arranged along the second direction.

[0119] In some examples, such as Figure 2As shown, the third spacer 133 is located in the spacing area surrounded by the first color sub-pixel 120A, the second color sub-pixel 120B and the third color sub-pixel 120C in the third pixel group 143, and the fourth spacer 134 is located in the spacing area surrounded by the first color sub-pixel 120A, the second color sub-pixel 120B and the third color sub-pixel 120C in the fourth pixel group 144.

[0120] In the display substrate provided in this example, since the first spacer, the second spacer, the third spacer and the fourth spacer are respectively located in the first pixel group, the second pixel group, the third pixel group and the fourth pixel group, for the multiple first color sub-pixels on the display substrate, there are four positions where spacers are provided, namely: some first color sub-pixels are provided with spacers on the first side in the first direction, some first color sub-pixels are provided with spacers on the second side in the second direction, some first color sub-pixels are provided with spacers on the third side in the second direction, and some first color sub-pixels are provided with spacers on the fourth side in the second direction. Therefore, when the FMM used to form the first color sub-pixels and the display substrate are displaced in one position, and some spacers cannot effectively support the FMM, the spacers in other positions can still effectively support the FMM, thereby preventing the FMM from scratching the film structure of the multiple sub-pixels on the display substrate, thereby avoiding various defects.

[0121] In some examples, such as Figure 2 As shown, the sizes of the third spacer 133 and the fourth spacer 134 are different. For example, the size of the third spacer 133 is larger than the size of the fourth spacer 134. As described above, since the third spacer 133 and the fourth spacer 134 are located in different environments, the space where the third spacer 133 is located is larger, so the size of the third spacer 131 can be set to be larger than the size of the fourth spacer 134, so that the third spacer 133 makes full use of the spacing area within the third pixel group 143, and the third spacer 133 can support the FMM in a larger range, thereby further reducing the risk of the FMM scratching the film structure of multiple sub-pixels on the display substrate.

[0122] In some examples, such as Figure 2 As shown, the sizes of the first spacer 131 and the third spacer 133 are substantially equal, and the sizes of the second spacer 132 and the fourth spacer 134 are substantially equal.

[0123] In some examples, such as Figure 2As shown, the third spacer 133 and the fourth spacer 134 have different shapes. As described above, since the third spacer 133 and the fourth spacer 134 are located in different environments, the third spacer 133 and the fourth spacer 134 can be set to specific shapes according to the environments, thereby making full use of the spacing area in the third pixel group 143 and the fourth pixel group 144.

[0124] For example, Figure 2 As shown, the third spacer 133 is rectangular in shape, and the fourth spacer 134 is circular in shape. Of course, the embodiments of the present disclosure include but are not limited to this, and the shapes of the third spacer and the fourth spacer can be set according to actual conditions.

[0125] In some examples, Figure 2 On the basis of the embodiment shown, the display substrate may only include the first spacer and the third spacer of larger size, without the second spacer and the fourth spacer, thereby reducing the density of the spacers.

[0126] In some examples, such as Figure 2 As shown, the display substrate 100 may also include a second virtual quadrilateral region B, a third virtual quadrilateral region C and a fourth virtual quadrilateral region D. The description of the second virtual quadrilateral region B, the third virtual quadrilateral region C and the fourth virtual quadrilateral region D can be found in Figure 1 The relevant description will not be repeated here.

[0127] In some examples, such as Figure 2 As shown, each spacer 130 is disposed adjacent to four sub-pixels 120, and no other sub-pixels exist between the spacer 130 and the adjacent sub-pixels 120. Thus, the spacer can be disposed in the area surrounded by the four sub-pixels, thereby fully utilizing the space on the display substrate.

[0128] In some examples, such as Figure 2 As shown, each spacer 130 is located between corners of four adjacent sub-pixels 120 , rather than between edges of adjacent sub-pixels.

[0129] In some examples, such as Figure 2 As shown, the display substrate 100 also includes a pixel partition structure 150, which includes a first pixel partition structure 151 and a second pixel partition structure 152; the first pixel partition structure 151 is located between adjacent first color sub-pixels 120A and second color sub-pixels 120B; the second pixel partition structure 152 is located between adjacent third color sub-pixels 120C and second color sub-pixels 120B, and each spacer 130 is located in the area between the two first pixel partition structures 151 and the two second pixel partition structures 152.

[0130] In the display substrate provided in this example, the display substrate 100 may adopt a tandem light-emitting technology (Tandem), that is, the light-emitting layer 122 of each sub-pixel 120 may include a plurality of light-emitting sub-layers and a charge generation layer between the light-emitting sub-layers. As a result, the display substrate 100 may have a higher luminous brightness and service life. When the display substrate 100 adopts a tandem light-emitting technology, the thickness of the light-emitting layer is relatively large and the height is relatively high. On the other hand, the pixel partition structure 150 may isolate the charge generation layer of adjacent sub-pixels 120 to prevent crosstalk. Each spacer 130 is located in the area between the two first pixel partition structures 151 and the two second pixel partition structures 152, the size of the spacer is further limited, and the thickness of the light-emitting layer is still relatively large, so when the FMM is not sufficiently supported, it is easier to scratch the light-emitting layer 122, causing various defects. In this case, by adopting the design of the spacer provided in the embodiment of the present disclosure, the display substrate can still avoid the FMM scratching the film layer structure of multiple sub-pixels on the display substrate, such as the organic light-emitting layer, while adopting the stacked light-emitting technology, thereby avoiding various defects, thereby having a higher display performance and a higher yield.

[0131] Figure 3A A partially enlarged schematic diagram of a display substrate provided by an embodiment of the present disclosure; Figure 3B A partially enlarged schematic diagram of another display substrate provided by an embodiment of the present disclosure.

[0132] like Figure 3A As shown, the display substrate 100 includes: a base substrate 110; a plurality of sub-pixels 120, which are located on the base substrate 110; and a plurality of spacers 130, each of which is located in the spacing area between adjacent sub-pixels 120. The plurality of sub-pixels 120 include a first color sub-pixel 120A, a second color sub-pixel 120B, and a third color sub-pixel 120C. The first color sub-pixel 120A is configured to emit light of a first color, the second color sub-pixel 120B is configured to emit light of a second color, and the third color sub-pixel 120C is configured to emit light of a third color. Each sub-pixel 120 may include an anode 121, a light-emitting layer 122, and a pixel opening 123, wherein the pixel opening 123 is located within the pixel defining layer, and the light-emitting layer 122 is arranged in contact with the anode 121 through the pixel opening 123. When forming the light-emitting layer 122 of each sub-pixel 120, the plurality of spacers 130 may be used to support the extremely fine metal mask FMM.

[0133] like Figure 3AAs shown, when the FMM and the display substrate 100 are displaced in the second direction Y, the spacer 130 may contact and scratch the edge of the opening of the FMM, thereby generating particles and causing the sub-pixel to emit light. On the other hand, when the FMM and the display substrate 100 are displaced in the second direction Y by a large distance, the spacer 130 may fall into the edge of the opening of the FMM and fail to support the FMM, thereby causing the FMM to scratch the light-emitting layer 122, causing various defects.

[0134] like Figure 3A As shown, the display substrate 100 may adopt a tandem light emitting technology (Tandem), that is, the light emitting layer 122 of each sub-pixel 120 may include a plurality of light emitting sub-layers and a charge generation layer between the light emitting sub-layers. Thus, the display substrate 100 may have a higher luminous brightness and service life. When the display substrate 100 adopts a tandem light emitting technology, the thickness of the light emitting layer is relatively large and the height is relatively high. On the other hand, in order to isolate the charge generation layer of the adjacent sub-pixels 120 and prevent crosstalk, the display substrate 100 is also provided with a pixel partition structure 150. In this way, the size of the spacer is further limited, and the thickness of the light emitting layer is still relatively large. Therefore, when the FMM is not sufficiently supported, it is easier to scratch the light emitting layer 122, causing various defects. In this case, by adopting the design scheme of the spacer provided in the embodiment of the present disclosure, the display substrate can still avoid the FMM from scratching the film structure of multiple sub-pixels on the display substrate, such as the organic light emitting layer, while adopting the tandem light emitting technology, thereby avoiding various defects, thereby having a higher display performance and a higher yield.

[0135] like Figure 3B As shown, the size of the spacer 130 used in the display substrate 100 is larger than Figure 3A The size of the spacer 130 in the display substrate is reduced, so the spacer can support the FMM in a larger range, thereby further reducing the risk of the FMM scratching the film layer structure of multiple sub-pixels on the display substrate.

[0136] Figure 4 FIG. 1 is a schematic diagram of another display substrate provided by an embodiment of the present disclosure. Figure 4As shown, the display substrate 100 includes: a base substrate 110; a plurality of sub-pixels 120, which are located on the base substrate 110; and a plurality of spacers 130, each spacer 130 being located in the spacing area between adjacent sub-pixels 120. The plurality of sub-pixels 120 include a first color sub-pixel 120A, a second color sub-pixel 120B, and a third color sub-pixel 120C. The first color sub-pixel 120A is configured to emit light of a first color, the second color sub-pixel 120B is configured to emit light of a second color, and the third color sub-pixel 120C is configured to emit light of a third color. When forming the organic light-emitting layer of each sub-pixel 120, the plurality of spacers 130 can be used to support an extremely fine metal mask; in addition, the organic light-emitting layers of the first color sub-pixel 120A, the second color sub-pixel 120B, and the third color sub-pixel 120C are usually formed using different extremely fine metal masks.

[0137] For example, the first color may be red, and its wavelength may be in the range of 620-750 nanometers, the second color may be green, and its wavelength may be in the range of 495-570 nanometers, and the third color may be blue, and its wavelength may be in the range of 450-495 nanometers.

[0138] like Figure 4 As shown, the display substrate 100 includes a first virtual quadrilateral region A, a plurality of spacers 130 include a first spacer 131 and a second spacer 132, a first spacer 131 and a second spacer 132 are respectively located at a first vertex P11 and a second vertex P12 of the first virtual quadrilateral region A; the first vertex P11 and the second vertex P12 are adjacent, or the first vertex P11 and the second vertex P12 are located at two ends of the same edge of the first virtual quadrilateral region A. Two first color sub-pixels 120A are located at two corners where the first vertex P11 and the second vertex P12 of the first virtual quadrilateral region A are located.

[0139] like Figure 4 As shown, the plurality of spacers 130 further include a third spacer 133 and a fourth spacer 134, a first spacer 133 and a second spacer 134 are respectively located at the third vertex P13 and the fourth vertex P14 of the first virtual quadrilateral region A; the third vertex P13 and the fourth vertex P14 are adjacent, or the third vertex P13 and the fourth vertex P14 are located at both ends of the same edge of the first virtual quadrilateral region A. The two second color sub-pixels 120B are respectively located at the two corners of the first virtual quadrilateral region A where the third vertex P13 and the fourth vertex P14 are located.

[0140] In the display substrate provided by the embodiment of the present disclosure, since the adjacent first and second vertices of the first virtual quadrilateral region are respectively provided with the first spacer and the second spacer, and the two corners where the first and second vertices are located are provided with two first color sub-pixels, therefore, for the two first color sub-pixels provided at the two corners where the first and second vertices are located, one of the two first color sub-pixels is provided with the first spacer in the first direction, and the other is provided with the second spacer in the second direction. That is to say, one of the two first color sub-pixels is adjacent to the first spacer in the first direction, and the other is adjacent to the second spacer in the second direction. When the FMM used to form the first color sub-pixel and the display substrate are displaced in the first direction or the second direction, and one of the first spacer and the second spacer of the adjacent first and second vertices of the first virtual quadrilateral region cannot effectively support the FMM, due to the small displacement of the dislocation in the other direction, the other of the first spacer and the second spacer can also effectively support the FMM, thereby preventing the FMM from scratching the film structure of multiple sub-pixels on the display substrate, such as the organic light-emitting layer, and thus avoiding various defects.

[0141] Similarly, since the third and fourth vertices adjacent to the first virtual quadrilateral region are respectively provided with the third spacer and the fourth spacer, and two second color sub-pixels are provided at the two corners where the third and fourth vertices are located, for the two second color sub-pixels provided at the two corners where the third and fourth vertices are located, one of the two second color sub-pixels is provided with the third spacer in the first direction, and the other is provided with the fourth spacer in the second direction. In other words, one of the two second color sub-pixels is adjacent to the third spacer in the first direction, and the other is adjacent to the fourth spacer in the second direction. When the FMM and the display substrate used to form the second color sub-pixel are displaced in the first direction or the second direction, and one of the third spacer and the fourth spacer of the adjacent third and fourth vertices of the first virtual quadrilateral region cannot effectively support the FMM, since the displacement of the dislocation in the other direction is small, the other of the third spacer and the fourth spacer can also effectively support the FMM, thereby preventing the FMM from scratching the film structure of multiple sub-pixels on the display substrate, such as the organic light-emitting layer, and thus avoiding various defects.

[0142] In summary, Figure 4 In the display substrate shown, two oppositely disposed edges of the first virtual quadrilateral region A correspond to two color sub-pixels, respectively. Thus, the spacers at the four vertices of the first virtual quadrilateral region A can provide effective support for the FMM of the two color sub-pixels.

[0143] In some examples, such as Figure 4 As shown, the plurality of sub-pixels 120 include a first pixel group 141, a second pixel group 142, a third pixel group 143 and a fourth pixel group 144; the first pixel group 141 includes a first color sub-pixel 120A and a third color sub-pixel 120C arranged along a first direction and two second color sub-pixels 120B arranged along a second direction; the second pixel group 142 includes two second color sub-pixels 120B arranged along the first direction and a first color sub-pixel 120A and a third color sub-pixel 120C arranged along the second direction; the arrangement of the sub-pixels 120 in the fourth pixel group 144 is mirror-symmetrical to the arrangement of the sub-pixels 120 in the second pixel group 142 with respect to a first virtual straight line extending along the first direction, and the arrangement of the sub-pixels 120 in the third pixel group 143 is mirror-symmetrical to the arrangement of the sub-pixels 120 in the first pixel group 141 with respect to a second virtual straight line extending along the second direction. That is, the third pixel group 143 includes the third color sub-pixel 120C and the first color sub-pixel 120A arranged along the first direction and two second color sub-pixels 120B arranged along the second direction, and the fourth pixel group 144 includes the two second color sub-pixels 120B arranged along the first direction and the third color sub-pixel 120C and the first color sub-pixel 120A arranged along the second direction. It can be seen that the types and quantities of sub-pixels in the first pixel group 141, the second pixel group 142, the third pixel group 143 and the fourth pixel group 144 are the same, but the arrangement methods are different.

[0144] In some examples, such as Figure 4 As shown, the first spacer 131 is located in the spaced area surrounded by the first color sub-pixel 120A, the second color sub-pixel 120B and the third color sub-pixel 120C in the first pixel group 141; the second spacer 132 is located in the spaced area surrounded by the first color sub-pixel 120A, the second color sub-pixel 120B and the third color sub-pixel 120C in the second pixel group 142; the third spacer 133 is located in the spaced area surrounded by the first color sub-pixel 120A, the second color sub-pixel 120B and the third color sub-pixel 120C in the third pixel group 143; and the fourth spacer 134 is located in the spaced area surrounded by the first color sub-pixel 120A, the second color sub-pixel 120B and the third color sub-pixel 120C in the second pixel group 142. In other words, the first spacer 131, the second spacer 132, the third spacer 133 and the fourth spacer 134 are located in different environments.

[0145] In some examples, such as Figure 4 As shown, the first vertex P11 and the third vertex P13 of the first virtual quadrilateral area A are adjacent.

[0146] In some examples, such as Figure 4As shown, the first virtual quadrilateral area A is a parallelogram.

[0147] In some examples, such as Figure 4 As shown, the length of the virtual side where the first vertex P11 and the second vertex P12 of the first virtual quadrilateral area A are located is greater than the size of the N first color sub-pixels 120A in the extension direction of the virtual side, and the value of N is greater than or equal to 2. In other words, the range or size of the first virtual quadrilateral area can be set according to actual needs.

[0148] In some examples, such as Figure 4 As shown, the display substrate 100 includes a second virtual quadrilateral region B, a first spacer 131 and a second spacer 132 are respectively located at the fifth vertex P21 and the sixth vertex P22 of the second virtual quadrilateral region B, and the fifth vertex P21 and the sixth vertex P22 are adjacent to each other or located at two end points of the same edge of the second virtual quadrilateral region B. Two second color sub-pixels 120B are located at two corners of the second virtual quadrilateral region B where the fifth vertex P21 and the sixth vertex P22 are located.

[0149] In the display substrate provided by the embodiment of the present disclosure, since the adjacent fifth and sixth vertices of the second virtual quadrilateral region are respectively provided with the first spacer and the second spacer, and the two corners where the fifth and sixth vertices are located are provided with two second color sub-pixels, therefore, for the two second color sub-pixels provided at the two corners where the fifth and sixth vertices are located, one of the two second color sub-pixels is provided with the first spacer in the first direction, and the other is provided with the second spacer in the second direction. That is to say, one of the two second color sub-pixels is adjacent to the first spacer in the first direction, and the other is adjacent to the second spacer in the second direction. When the FMM and the display substrate used to form the second color sub-pixel are displaced in the first direction or the second direction, and one of the first spacer and the second spacer of the adjacent fifth and sixth vertices of the second virtual quadrilateral region cannot effectively support the FMM, due to the small displacement of the dislocation in the other direction, the other of the first spacer and the second spacer can also effectively support the FMM, thereby preventing the FMM from scratching the film structure of multiple sub-pixels on the display substrate, such as the organic light-emitting layer, thereby avoiding various defects.

[0150] In some examples, such as Figure 4 As shown, the shape of the second virtual quadrilateral region B is a parallelogram. Two second color sub-pixels 120B are arranged at the corners where the other two vertices of the second virtual quadrilateral region B are located.

[0151] In some examples, such as Figure 4As shown, the display substrate 100 includes a third virtual quadrilateral area C, a first spacer 131 and a second spacer 132 are respectively located at the seventh vertex P31 and the eighth vertex P32 of the third virtual quadrilateral area C, and the seventh vertex P31 and the eighth vertex P32 are adjacent to each other, or are two endpoints on the same virtual side of the third virtual quadrilateral area C. Two third color sub-pixels 120C are located at two corners of the third virtual quadrilateral area C where the seventh vertex P31 and the eighth vertex P32 are located. It should be noted that Figure 4 The rectangular blocks shown in A, B, C, and D are not actual structures, but schematically illustrate the range of the above-mentioned various virtual quadrilateral areas; and the edges of the above-mentioned various virtual quadrilateral areas are defined by the above-mentioned vertices or the centers of the spacers, not by the above-mentioned rectangular blocks shown in A, B, C, and D.

[0152] In the display substrate provided by the embodiment of the present disclosure, since the adjacent seventh and eighth vertices of the third virtual quadrilateral region are respectively provided with the first spacer and the second spacer, and the two corners where the seventh and eighth vertices are located are provided with two second color sub-pixels, therefore, for the two third color sub-pixels provided at the two corners where the seventh and eighth vertices are located, one of the two third color sub-pixels is provided with the first spacer in the first direction, and the other is provided with the second spacer in the second direction. That is to say, one of the two third color sub-pixels is adjacent to the first spacer in the first direction, and the other is adjacent to the second spacer in the second direction. When the FMM used to form the third color sub-pixel and the display substrate are displaced in the first direction or the second direction, and one of the first spacer and the second spacer of the adjacent seventh and eighth vertices of the third virtual quadrilateral region cannot effectively support the FMM, due to the small displacement of the dislocation in the other direction, the other of the first spacer and the second spacer can also effectively support the FMM, thereby preventing the FMM from scratching the film structure of multiple sub-pixels on the display substrate, such as the organic light-emitting layer, thereby avoiding various defects.

[0153] In some examples, such as Figure 4 As shown, the shape of the third virtual quadrilateral region C is a parallelogram. Two third color sub-pixels 120C are arranged at the corners where the other two vertices of the second virtual quadrilateral region B are located.

[0154] In some examples, such as Figure 4 As shown, the length of the virtual side where the seventh vertex P31 and the eighth vertex P32 of the third virtual quadrilateral area C are located is greater than the size of the N third color sub-pixels 120C in the extension direction of the virtual side, and the value of N is greater than or equal to 2. In other words, the range or size of the third virtual quadrilateral area can be set according to actual needs.

[0155] In some examples, such as Figure 4 As shown, the display substrate 100 may further include a fourth virtual quadrilateral region D, a first spacer 131 and a second spacer 132 are respectively located at the ninth vertex P41 and the tenth vertex P42 of the fourth virtual quadrilateral region D, and the ninth vertex P41 and the tenth vertex P42 are adjacent to each other, or are two end points on the same virtual side of the fourth virtual quadrilateral region D. The two second color sub-pixels 120B are located at the two corners where the ninth vertex P41 and the tenth vertex P42 of the third virtual quadrilateral region C are located. It should be noted that Figure 4 The rectangular blocks shown in A, B, C, and D are not actual structures, but schematically illustrate the range of the above-mentioned various virtual quadrilateral areas; and the edges of the above-mentioned various virtual quadrilateral areas are defined by the above-mentioned vertices or the centers of the spacers, not by the above-mentioned rectangular blocks shown in A, B, C, and D.

[0156] In the display substrate provided by the embodiment of the present disclosure, since the adjacent ninth and tenth vertices of the fourth virtual quadrilateral region are respectively provided with the first spacer and the second spacer, and the two corners where the ninth and tenth vertices are located are provided with two second color sub-pixels, therefore, for the two second color sub-pixels provided at the two corners where the ninth and tenth vertices are located, one of the two second color sub-pixels is provided with the first spacer in the first direction, and the other is provided with the second spacer in the second direction. That is to say, one of the two second color sub-pixels is adjacent to the first spacer in the first direction, and the other is adjacent to the second spacer in the second direction. When the FMM and the display substrate used to form the third color sub-pixel are displaced in the first direction or the second direction, and one of the first spacer and the second spacer of the adjacent ninth and tenth vertices of the fourth virtual quadrilateral region cannot effectively support the FMM, due to the small displacement of the dislocation in the other direction, the other of the first spacer and the second spacer can also effectively support the FMM, thereby preventing the FMM from scratching the film structure of multiple sub-pixels on the display substrate, such as the organic light-emitting layer, thereby avoiding various defects.

[0157] In some examples, such as Figure 4 As shown, the shape of the fourth virtual quadrilateral region D is a parallelogram. Two first color sub-pixels 120A are arranged at the corners where the other two vertices of the fourth virtual quadrilateral region D are located.

[0158] In some examples, such as Figure 4As shown, each spacer 130 is disposed adjacent to four sub-pixels 120, and no other sub-pixels exist between the spacer 130 and the adjacent sub-pixels 120. Thus, the spacer can be disposed in the area surrounded by the four sub-pixels, thereby fully utilizing the space on the display substrate.

[0159] In some examples, such as Figure 4 As shown, each spacer 130 is located between corners of four adjacent sub-pixels 120 , rather than between edges of adjacent sub-pixels.

[0160] In some examples, such as Figure 4 As shown, the display substrate 100 includes a base substrate 110, a plurality of sub-pixels 120 and a plurality of spacers 130; the plurality of sub-pixels 120 are located on the base substrate 110 and include a first color sub-pixel 120A, a second color sub-pixel 120B and a third color sub-pixel 120C; each spacer 130 is located in the spacing area between adjacent sub-pixels 120. The plurality of sub-pixels 120 include a plurality of first sub-pixel rows 161 and a plurality of first sub-pixel columns 171, each first sub-pixel row 161 includes a plurality of first color sub-pixels 120A and a plurality of third color sub-pixels 120C alternately arranged along a first direction, each first sub-pixel column 171 includes a plurality of first color sub-pixels 120A and a plurality of third color sub-pixels 120C alternately arranged along a second direction, the plurality of first sub-pixel rows 161 are arranged along the second direction, the plurality of first sub-pixel columns 171 are arranged along the first direction, and the first direction and the second direction intersect. The plurality of spacers 130 include a first spacer 131 and a second spacer 132.

[0161] like Figure 4 As shown, a plurality of first sub-pixel rows 161 include a plurality of first pixel spacer rows 1615, each first pixel spacer row 1615 includes a first spacer 131, and is located between the first color sub-pixel 120A and the third color sub-pixel 120C adjacent to each other in the first direction; a plurality of first sub-pixel columns 171 include a plurality of first pixel spacer columns 1715, each first pixel spacer column 1715 includes a second spacer 132, and is located between the first color sub-pixel 120A and the third color sub-pixel 120C adjacent to each other in the second direction.

[0162] In the display substrate provided by the embodiment of the present disclosure, since each first pixel spacer row 1615 includes a first spacer 131, which is located between the first color sub-pixel 120A and the third color sub-pixel 120C adjacent in the first direction, and each first pixel spacer column 1715 includes a second spacer 132, which is located between the first color sub-pixel 120A and the third color sub-pixel 120C adjacent in the second direction, for the first color sub-pixel, part of the first color sub-pixel is provided with the first spacer in the first direction, and part of the first color sub-pixel is provided with the second spacer in the second direction. When the FMM used to form the first color sub-pixel and the display substrate are displaced in the first direction or the second direction, and one of the first spacer and the second spacer cannot effectively support the FMM, since the displacement of the dislocation in the other direction is small, the other of the first spacer and the second spacer can still effectively support the FMM, thereby preventing the FMM from scratching the film structure of multiple sub-pixels on the display substrate, such as the organic light-emitting layer, and thus avoiding various defects.

[0163] Similarly, for the third color sub-pixel, some of the third color sub-pixels are provided with a first spacer in the first direction, and some of the third color sub-pixels are provided with a second spacer in the second direction. When the FMM and the display substrate used to form the third color sub-pixel are displaced in the first direction or the second direction, and one of the first spacer and the second spacer cannot effectively support the FMM, since the displacement of the dislocation in the other direction is smaller, the other of the first spacer and the second spacer can still effectively support the FMM, thereby preventing the FMM from scratching the film structure of multiple sub-pixels on the display substrate, such as the organic light-emitting layer, and thus avoiding various defects.

[0164] For example, the first direction is perpendicular to the second direction. Of course, the embodiments of the present disclosure include but are not limited to this, and the first direction and the second direction may not be perpendicular.

[0165] In some examples, such as Figure 4 As shown, in the plurality of first sub-pixel rows 161, the plurality of first pixel spacer rows 1615 are unevenly distributed. For example, two adjacent first pixel spacer rows 1615 are directly adjacent, and the other two adjacent first pixel spacer rows 1615 are arranged with one first sub-pixel row 161 between them. Thus, the display substrate can further reduce the risk of scratches.

[0166] In some examples, such as Figure 4As shown, in the plurality of first sub-pixel columns 171, the plurality of first pixel spacer columns 1715 are unevenly distributed. For example, two adjacent first pixel spacer columns 1715 are arranged with one first sub-pixel column 171 between them, and the other two adjacent first pixel spacer columns 1715 are directly adjacent. Thus, the display substrate can further reduce the risk of scratches.

[0167] In some examples, such as Figure 4 As shown, the first spacers 131 in two adjacent first pixel spacer rows 1615 in the second direction are staggered, that is, the corresponding first spacers 131 in two adjacent first pixel spacer rows 1615 in the second direction are not located on the same straight line extending along the second direction.

[0168] In some examples, such as Figure 4 As shown, the second spacers 132 in the first pixel spacer columns 1715 adjacent to each other in the first direction are staggered, that is, the corresponding second spacers 132 in the first pixel spacer columns 1715 adjacent to each other in the first direction are not located on the same straight line extending along the first direction.

[0169] In some examples, such as Figure 4 As shown, the multiple sub-pixels 120 include multiple second sub-pixel rows 162 and multiple second sub-pixel columns 172, each second sub-pixel row 162 includes multiple second color sub-pixels 120B alternately arranged along the first direction, each second sub-pixel column 172 includes multiple second color sub-pixels 120B alternately arranged along the second direction, the multiple second sub-pixel rows 162 are arranged along the second direction, and the multiple second sub-pixel columns 172 are arranged along the first direction.

[0170] In some examples, such as Figure 4 As shown, the plurality of second sub-pixel rows 162 include a plurality of second pixel spacer rows 1625, each second pixel spacer row 1625 includes a second spacer 132, and is located between the second color sub-pixels 120B adjacent to each other in the first direction; the plurality of second sub-pixel columns 172 include a plurality of second pixel spacer columns 1725, each second pixel spacer column 1725 includes a first spacer 131, and is located between the second color sub-pixels 120B adjacent to each other in the second direction.

[0171] In the display substrate provided by the embodiment of the present disclosure, since each second pixel spacer row 1625 includes a second spacer 132, which is located between the second color sub-pixels 120B adjacent in the first direction, and each second pixel spacer column 1725 includes a first spacer 131, which is located between the second color sub-pixels 120B adjacent in the second direction, for the second color sub-pixels, some of the second color sub-pixels are provided with the second spacer in the first direction, and some of the second color sub-pixels are provided with the first spacer in the second direction. When the FMM used to form the second color sub-pixels and the display substrate are displaced in the first direction or the second direction, and one of the first spacer and the second spacer cannot effectively support the FMM, since the displacement of the dislocation in the other direction is small, the other of the first spacer and the second spacer can still effectively support the FMM, thereby preventing the FMM from scratching the film structure of multiple sub-pixels on the display substrate, such as the organic light-emitting layer, and thus avoiding various defects.

[0172] In some examples, such as Figure 4 As shown, a plurality of first sub-pixel rows 161 and a plurality of second sub-pixel rows 162 are alternately arranged in the second direction, and a plurality of first sub-pixel columns 171 and a plurality of second sub-pixel columns 172 are alternately arranged in the first direction.

[0173] In some examples, such as Figure 4 As shown, in the plurality of second sub-pixel rows 162, the plurality of second pixel spacer rows 1625 are unevenly distributed. Thus, the display substrate can further reduce the risk of scratches.

[0174] In some examples, such as Figure 4 As shown, in the plurality of second sub-pixel columns 172, the plurality of second pixel spacer columns 1725 are unevenly distributed. Thus, the display substrate can further reduce the risk of scratches.

[0175] In some examples, such as Figure 4 As shown, the second spacers 132 in two second pixel spacer rows 1625 adjacent in the second direction are staggered, that is, the corresponding second spacers 132 in two second pixel spacer rows 1625 adjacent in the second direction are not located on the same straight line extending along the second direction.

[0176] In some examples, such as Figure 4 As shown, the first spacers 131 in the second pixel spacer columns 1725 adjacent in the first direction are staggered, that is, the corresponding first spacers 131 in the second pixel spacer columns 1725 adjacent in the first direction are not located on the same straight line extending along the first direction.

[0177] Figure 5FIG. 1 is a schematic plan view of another display substrate provided by an embodiment of the present disclosure. Figure 5 As shown, the display substrate 100 includes: a base substrate 110; a plurality of sub-pixels 120, which are located on the base substrate 110; and a plurality of spacers 130, each spacer 130 being located in the spacing area between adjacent sub-pixels 120. The plurality of sub-pixels 120 include a first color sub-pixel 120A, a second color sub-pixel 120B, and a third color sub-pixel 120C. The first color sub-pixel 120A is configured to emit light of a first color, the second color sub-pixel 120B is configured to emit light of a second color, and the third color sub-pixel 120C is configured to emit light of a third color. When forming the organic light-emitting layer of each sub-pixel 120, the plurality of spacers 130 can be used to support an extremely fine metal mask; in addition, the organic light-emitting layers of the first color sub-pixel 120A, the second color sub-pixel 120B, and the third color sub-pixel 120C are usually formed using different extremely fine metal masks.

[0178] For example, the first color may be red, and its wavelength may be in the range of 620-750 nanometers, the second color may be green, and its wavelength may be in the range of 495-570 nanometers, and the third color may be blue, and its wavelength may be in the range of 450-495 nanometers.

[0179] like Figure 5 As shown, the display substrate 100 includes a first virtual quadrilateral area A, and the plurality of spacers 130 include a first spacer 131 and a second spacer 132; the shape of the first virtual quadrilateral area A is a trapezoid; a first spacer 131 and a second spacer 132 are respectively located at a first vertex P11 and a second vertex P12 of the first virtual quadrilateral area A, the first vertex P11 and the second vertex P12 are adjacent, or the first vertex P11 and the second vertex P12 are located at two ends of the same edge of the first virtual quadrilateral area A. ends; a first spacer 131 and a second spacer 132 are respectively located at the third vertex P13 and the fourth vertex P14 of the first virtual quadrilateral area A, the third vertex P13 and the fourth vertex P14 are adjacent, or the third vertex P13 and the fourth vertex P14 are located at both ends of the same edge of the first virtual quadrilateral area A; the four second color sub-pixels 120B are located at the two corners where the first vertex P11, the second vertex P12, the third vertex P13 and the fourth vertex P14 of the first virtual quadrilateral area A are located.

[0180] In the display substrate provided by the embodiment of the present disclosure, since the first vertex, the second vertex, the third vertex and the fourth vertex of the first virtual quadrilateral region are respectively provided with the first spacer and the second spacer, and the two corners where the four vertices are located are provided with four second color sub-pixels, spacers are provided in four directions for the four second color sub-pixels. When the FMM used to form the second color sub-pixels and the display substrate are displaced in the first direction or the second direction, and one of the four spacers cannot effectively support the FMM, the other spacers can still effectively support the FMM, thereby preventing the FMM from scratching the film structure of multiple sub-pixels on the display substrate, such as the organic light-emitting layer, and thus avoiding various defects.

[0181] In some examples, such as Figure 5 As shown, the plurality of sub-pixels 120 include a first pixel group 141 and a second pixel group 142; the first pixel group 141 includes a first color sub-pixel 120A and a third color sub-pixel 120C arranged along a first direction and two second color sub-pixels 120B arranged along a second direction, and the second pixel group 142 includes two second color sub-pixels 120B arranged along the first direction and a first color sub-pixel 120A and a third color sub-pixel 120C arranged along the second direction. It can be seen that the types and quantities of the sub-pixels in the first pixel group 141 and the second pixel group 142 are the same, but the arrangement methods are different.

[0182] In some examples, such as Figure 5 As shown, the first spacer 131 and the third spacer 133 are located in the spacing area surrounded by the first color sub-pixel 120A, the second color sub-pixel 120B and the third color sub-pixel 120C in the first pixel group 141, and the second spacer 132 and the fourth spacer 134 are located in the spacing area surrounded by the first color sub-pixel 120A, the second color sub-pixel 120B and the third color sub-pixel 120C in the second pixel group 142.

[0183] In the display substrate provided in this example, for the first color sub-pixel in the first pixel group, the first spacer is located on one side of the first color sub-pixel in the first direction, and for the first color sub-pixel in the second pixel group, the second spacer is located on one side of the first color sub-pixel in the second direction. When the FMM and the display substrate used to form the first color sub-pixel are displaced in the first direction or the second direction, and one of the first spacer and the second spacer cannot effectively support the FMM, since the displacement of the dislocation in the other direction is smaller, the other of the first spacer and the second spacer can still effectively support the FMM, thereby preventing the FMM from scratching the film layer structure of multiple sub-pixels on the display substrate, thereby avoiding various defects.

[0184] Similarly, for the third color sub-pixel in the first pixel group, the first spacer is located on one side of the third color sub-pixel in the first direction, and for the third color sub-pixel in the second pixel group, the second spacer is located on one side of the third color sub-pixel in the second direction. When the FMM and the display substrate used to form the third color sub-pixel are displaced in the first direction or the second direction, and one of the first spacer and the second spacer cannot effectively support the FMM, since the displacement of the dislocation in the other direction is smaller, the other of the first spacer and the second spacer can still effectively support the FMM, thereby preventing the FMM from scratching the film layer structure of multiple sub-pixels on the display substrate, thereby avoiding various defects.

[0185] Similarly, for the second color sub-pixel in the first pixel group, the first spacer is located on one side of the second color sub-pixel in the second direction, and for the second color sub-pixel in the second pixel group, the second spacer is located on one side of the second color sub-pixel in the first direction. When the FMM and the display substrate used to form the second color sub-pixel are displaced in the first direction or the second direction, and one of the first spacer and the second spacer cannot effectively support the FMM, since the displacement of the dislocation in the other direction is smaller, the other of the first spacer and the second spacer can still effectively support the FMM, thereby preventing the FMM from scratching the film structure of multiple sub-pixels on the display substrate, thereby avoiding various defects.

[0186] Fig. 6A is a cross-sectional schematic diagram of a spacer; Figure 6B A schematic plan view of another spacer provided in one embodiment of the present disclosure; Figure 6C Another spacer provided in an embodiment of the present disclosure is Figure 6B Schematic diagram of the cross section of line AB in the figure. Fig. 6A As shown, since the spacers are usually made of organic materials, there is a slope at the edge of the spacers, which makes the edge of the spacers lower in height and the supporting effect weaker. Figure 6B and 6C As shown, the spacer 130 includes a plurality of sub-spacers 1305 spaced apart. Thus, by configuring the spacer as a plurality of sub-spacers 1305 spaced apart, the edge of the spacer 130 also has a relatively high height, so that the edge of the spacer also has a better supporting effect. It should be noted that the plurality of sub-spacers may share a base or may be independently configured. This is not limited in the embodiments of the present disclosure. In addition, Figure 6B and Figure 6C The spacers shown can be used for Figures 1 to 5 Any spacer in the.

[0187] For example, Figure 6B As shown, the spacer 130 includes four sub-spacer portions 1305 arranged at intervals, and the four sub-spacers 1305 form a 2*2 matrix. Of course, the embodiments of the present disclosure include but are not limited to this. Figure 7 Schematic diagram of a display device provided by an embodiment of the present disclosure. Figure 7 As shown, the display device 500 includes the display substrate 100 provided in any of the above examples. Therefore, the display device can also effectively prevent the FMM from scratching the film structure of multiple sub-pixels on the display substrate, such as the organic light-emitting layer, thereby avoiding various defects.

[0188] In some examples, the display device may use a stacked light emitting technology to have higher light emitting brightness and longer service life.

[0189] In some examples, the display device may be any product or component with a display function, such as a television, a digital camera, a mobile phone, a watch, a tablet computer, a laptop computer, a navigator, etc., but the present embodiment is not limited thereto.

[0191] (1) In the drawings of the embodiments of the present disclosure, only the structures related to the embodiments of the present disclosure are involved, and other structures can refer to the general design.

[0192] (2) In the absence of conflict, features in the same embodiment or in different embodiments of the present disclosure may be combined with each other.
