Display substrate and display device

[0001] This application claims priority to Chinese Patent Application No. 2024106676187, filed May 27, 2024, the disclosure of which is incorporated herein in its entirety by this reference. TECHNICAL FIELD

[0002] Embodiments of the present disclosure relate to a display substrate and a display device. BACKGROUND

[0003] Active-matrix organic light-emitting diode display devices (AMOLED) have become a research hotspot and a direction of technical development for current manufacturers due to their advantages of wide color gamut, high contrast, thin design, self-emission, bright color, low power consumption, wide viewing angle, and the like. Currently, active-matrix organic light-emitting diode display devices have been widely applied to various electronic products, from small electronic products such as smart bracelets, smart watches, smart phones, tablet computers, and the like, to large electronic products such as notebook computers, desktop computers, televisions, and the like. Therefore, the market demand for active-matrix organic light-emitting diode display devices is also increasingly strong.

[0004] The light-emitting principle of an active-matrix organic light-emitting diode display device is as follows: a 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; during light-emitting display, electrons and holes are injected into an electron transport layer and a hole transport layer from the cathode and the anode, respectively, and then the electrons and the 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. SUMMARY

[0005] This disclosure provides a display substrate and a display device. Since adjacent first vertices and second vertices of a first virtual quadrilateral region are respectively provided with first spacers and second spacers, and two first color sub-pixels are provided at the two corners where the first and second vertices are located, for the two first color sub-pixels at the two corners where the first and second vertices are located, one of these two first color sub-pixels is provided with a first spacer in a first direction, and the other is provided with a second spacer in a second direction. That is, one of these 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 misaligned in the first or second direction, causing one of the first and second spacers at the adjacent first and second vertices of the first virtual quadrilateral region to be unable to effectively support the FMM, since the displacement in the other direction is small, the other of the first and second spacers can still effectively support the FMM, thereby preventing the FMM from scraping against the film structure of multiple sub-pixels on the display substrate, such as the organic light-emitting layer, and thus avoiding various defects.

[0006] At least one embodiment of this disclosure provides a display substrate, comprising: a substrate; a plurality of sub-pixels located on the substrate; and a plurality of spacers, each spacer located in a spacing region between adjacent sub-pixels. The plurality of sub-pixels includes a first color sub-pixel, a second color sub-pixel, and a third color sub-pixel. The display substrate includes a first virtual quadrilateral region. The plurality of spacers includes a first spacer and a second spacer. One first spacer and one second spacer are respectively located at a first vertex and a second vertex of the first virtual quadrilateral region, the first vertex and the second vertex being adjacent. Two first color sub-pixels are located at the two corners where the first vertex and the second vertex of the first virtual quadrilateral region are located.

The first pixel group includes a first color sub-pixel and a third color sub-pixel arranged along a first direction and two second color sub-pixels arranged along a second direction. The second pixel group includes two second color sub-pixels arranged along the first direction and a first color sub-pixel and a third color sub-pixel arranged along the second direction. The first spacer is located in the interval region surrounded by the first color sub-pixel, the second color sub-pixel and the third color sub-pixel in the first pixel group. The second spacer is located in the interval region surrounded by the first color sub-pixel, the second color sub-pixel and the third color sub-pixel in the second pixel group.

[0008] For example, in a display substrate provided in an embodiment of this disclosure, the plurality of spacers include a third spacer and a fourth spacer. The third spacer and the fourth spacer are respectively located at the third vertex and the fourth vertex of the first virtual quadrilateral region. The third vertex and the fourth vertex are adjacent to each other, and two first color sub-pixels are located at the two corners where the third vertex and the fourth vertex of the first virtual quadrilateral region are located.

[0009] For example, in a display substrate provided in an embodiment of this disclosure, the plurality of sub-pixels includes a third pixel group and a fourth pixel group. The arrangement of the sub-pixels in the fourth pixel group is mirror-symmetrical with respect to the arrangement of the sub-pixels in the second pixel group with respect to a first virtual straight line extending along the first direction. The arrangement of the sub-pixels in the third pixel group is mirror-symmetrical with respect to the arrangement of the sub-pixels in the first pixel group with respect to a second virtual straight line extending along the second direction. The third spacer is located in the interval region surrounded by the first color sub-pixel, the second color sub-pixel, and the third color sub-pixel in the third pixel group. The fourth spacer is located in the interval region surrounded by the first color sub-pixel, the second color sub-pixel, and the third color sub-pixel in the fourth pixel group.

[0046] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Based on the described embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0047] Unless otherwise defined, the technical or scientific terms used in this disclosure shall have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. The terms “first,” “second,” and similar terms used in this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as “comprising” or “including” mean that an element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects.

[0048] The features such as "parallel," "perpendicular," and "identical" used in the embodiments of this disclosure include features in the strict sense of "parallel," "perpendicular," and "identical," as well as cases where "approximately parallel," "approximately perpendicular," and "approximately identical" include certain errors. Considering measurement and errors associated with the measurement of a specific quantity (e.g., limitations of the measurement system), they represent the acceptable deviation range for a specific value as determined by a person skilled in the art. For example, "approximately" can mean within one or more standard deviations, or within 10% or 5% of said value. Unless otherwise specified in the following embodiments of this disclosure, the quantity of a component is implied to mean that the component can be one or more, or can be understood as at least one. "At least one" means one or more, and "more" means at least two. In the embodiments of this disclosure, "same layer" refers to the relationship between multiple film layers formed from the same material after undergoing the same step (e.g., a patterning process). Here, "same layer" does not always mean that multiple film layers have the same thickness or that multiple film layers have the same height in a cross-sectional view.

[0049] In the fabrication process of active-matrix organic light-emitting diode (OLED) displays, the organic light-emitting layer is typically formed using a fine metal mask (FMM) through a vapor deposition process. During this process, spacers (PS) need to be placed on the display substrate to support the FMM and prevent it from scratching the organic light-emitting layer, which could lead to various defects. Therefore, the morphology, quantity, position, density, and other parameters of the spacers need to be comprehensively considered in conjunction with process requirements and the characteristics of different products, and a balanced design is required.

[0050] The inventors of this application have noticed that in actual manufacturing processes, the relative positions of the FMM and the display substrate are prone to misalignment. Since the spacers are typically placed in the same environment, this results in insufficient margin of the FMM for R / G / B sub-pixels in the X or Y directions. When misalignment occurs in the X or Y direction, a large number, or even all, of the spacers cannot effectively support the FMM, making it easy for the FMM to rub against the organic light-emitting layer in the pixel opening, thus causing various defects. It should be noted that the aforementioned "same environment" refers to the fact that the type, number, and arrangement of sub-pixels surrounding different spacer locations are the same.

[0051] In this embodiment, a display substrate is provided, comprising: a substrate; a plurality of sub-pixels located on the substrate; and a plurality of spacers located in the spacing region between adjacent sub-pixels. The plurality of sub-pixels includes a first color sub-pixel, a second color sub-pixel, and a third color sub-pixel. The display substrate includes a first virtual quadrilateral region, and the plurality of spacers includes a first spacer and a second spacer. A first spacer and a second spacer are respectively located at a first vertex and a second vertex of the first virtual quadrilateral region, the first vertex and the second vertex being adjacent. Two first color sub-pixels are located at the two corners where the first vertex and the second vertex of the first virtual quadrilateral region are located. Since the adjacent first vertex and the second vertex 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 vertex and the second vertex are located, for the two first color sub-pixels located at the two corners where the first vertex and the second vertex are located, one of these two first color sub-pixels is provided with a first spacer in a first direction, and the other is provided with a second spacer in a second direction. In other words, 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 misaligned in the first or second direction, causing one of the first and second spacers at the adjacent first and second vertices of the first virtual quadrilateral region to fail to effectively support the FMM, the other of the first and second spacers can still effectively support the FMM because the displacement in the other direction is smaller. This prevents the FMM from scraping against the film structure of multiple sub-pixels on the display substrate, such as the organic light-emitting layer, and thus avoids various defects.

[0052] This disclosure also provides a display device including the aforementioned display substrate. Therefore, this display device can also avoid FMM scraping against multiple sub-pixels on the display substrate, thereby avoiding various defects and achieving higher product yield and higher display quality.

[0053] The display substrate and display device provided in the embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0054] Figure 1 is a planar schematic diagram of a display substrate according to an embodiment of the present disclosure. As shown in Figure 1, the display substrate 100 includes: a substrate 110; a plurality of sub-pixels 120 located on the substrate 110; and a plurality of spacers 130, each spacer 130 being located in the spacing region between adjacent sub-pixels 120. The plurality of sub-pixels 120 includes 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 ultrafine 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 typically formed using different ultrafine metal masks.

[0055] For example, the first color mentioned above can be red, with a wavelength range of 620-750 nanometers; the second color can be green, with a wavelength range of 495-570 nanometers; and the third color can be blue, with a wavelength range of 450-495 nanometers.

[0056] As shown in Figure 1, the display substrate 100 includes a first virtual quadrilateral region A. Multiple 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 opposite ends of the same edge of the first virtual quadrilateral region A. Two first color sub-pixels 120A are located at the two corners where the first vertex P11 and the second vertex P12 of the first virtual quadrilateral region A are located.

[0057] In the display substrate provided in this embodiment, since the adjacent first vertices and second vertices of the first virtual quadrilateral region are respectively provided with first spacers and second spacers, and two first color sub-pixels are provided at the two corners where the first and second vertices are located, 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, 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 misaligned in the first or second direction, and one of the first spacers and second spacers of the adjacent first and second vertices of the first virtual quadrilateral region cannot effectively support the FMM, since the displacement in the other direction is small, the other of the first spacers and second 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.

[0058] In some examples, as shown in Figure 1, multiple 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. 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 first pixel group 141 and the second pixel group 142 have the same type and number of sub-pixels, but their arrangement is different.

[0059] In some examples, as shown in Figure 1, the first spacer 131 is located within 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 within 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. That is, the first spacer 131 and the second spacer 132 are in different environments.

[0060] 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 used to form the first color sub-pixel and the display substrate are misaligned in the first or second direction, causing one of the first and second spacers to fail to effectively support the FMM, since the displacement in the other direction is small, the other of the first and second spacers can still effectively support the FMM, thereby preventing the FMM from scratching the film structure of multiple sub-pixels on the display substrate, and thus avoiding various defects.

[0061] 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, while 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 used to form the third color sub-pixel and the display substrate are misaligned in the first or second direction, causing one of the first and second spacers to fail to effectively support the FMM, since the displacement in the other direction is small, the other of the first and second spacers can still effectively support the FMM, thereby preventing the FMM from scratching the film structure of multiple sub-pixels on the display substrate, and thus avoiding various defects.

[0062] 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, while 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 used to form the second color sub-pixel and the display substrate are misaligned in the first or second direction, causing one of the first and second spacers to fail to effectively support the FMM, since the displacement in the other direction is small, the other of the first and second spacers can still effectively support the FMM, thereby preventing the FMM from scratching the film structure of multiple sub-pixels on the display substrate, and thus avoiding various defects.

[0063] In some examples, as shown in Figure 1, 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 located at the third vertex P13 and the fourth vertex P14 of the first virtual quadrilateral region A, respectively. The third vertex P13 and the fourth vertex P14 are adjacent, or the third vertex P13 and the fourth vertex P14 are located at the two endpoints of an edge of the first virtual quadrilateral region A. It should be noted that the third vertex P13 and the fourth vertex P14 are different vertices from the first vertex P11 and the second vertex P12.

[0064] In some examples, as shown in Figure 1, two first color sub-pixels 120A are located at the two corners of the third vertex P13 and the fourth vertex P14 of the first virtual quadrilateral region A. Since the adjacent first and second vertices of the first virtual quadrilateral region are respectively provided with first and second spacers, and the adjacent third and fourth vertices are respectively provided with third and fourth spacers, and four first color sub-pixels are provided at the four corners of the first, second, third, and fourth vertices of the first virtual quadrilateral region, for the four first color sub-pixels provided at the four corners of the first, second, third, and fourth vertices, the first of these four first color sub-pixels has a first spacer on the first side in the first direction, the second of these four first color sub-pixels has a third spacer on the second side in the first direction, the third of these four first color sub-pixels has a second spacer on the third side in the second direction, and the fourth of these four first color sub-pixels has a fourth spacer on the fourth side in the second direction. When the FMM used to form the first color sub-pixel and the display substrate shift in a first direction towards a first side, causing the first spacer to fail to effectively support the FMM, the second, third, and fourth spacers can still effectively support the FMM, thereby preventing the FMM from scraping against 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 shifting occurs in other directions, the FMM can also be prevented from scraping against the film structure of multiple sub-pixels on the display substrate, which will not be elaborated further here.

[0065] In some examples, as shown in Figure 1, the first vertex P11 and the fourth vertex P14 of the first virtual quadrilateral region A are adjacent.

[0066] In some examples, as shown in Figure 1, the plurality of sub-pixels 120 includes a third pixel group 143 and a fourth pixel group 144. The arrangement of sub-pixels 120 in the fourth pixel group 144 is mirror-symmetrical with respect to the arrangement of sub-pixels 120 in the second pixel group 142 with respect to a first virtual straight line extending along a first direction. The arrangement of sub-pixels 120 in the third pixel group 143 is mirror-symmetrical with respect to the arrangement of sub-pixels 120 in the first pixel group 141 with respect to a second virtual straight line extending along a second direction. That is, the third pixel group 143 includes a third color sub-pixel 120C and a first color sub-pixel 120A arranged along the first direction and two second color sub-pixels 120B arranged along the second direction. The fourth pixel group 144 includes two second color sub-pixels 120B arranged along the first direction and a third color sub-pixel 120C and a first color sub-pixel 120A arranged along the second direction.

[0067] In some examples, as shown in Figure 1, 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 fourth pixel group 144.

[0068] In the display substrate provided in this example, since the first spacer, second spacer, third spacer, and fourth spacer are located in the first pixel group, second pixel group, third pixel group, and fourth pixel group, respectively, for the multiple first color sub-pixels on the display substrate, there are four possible orientations where spacers are provided. That is, some first color sub-pixels have spacers on the first side in the first direction, some first color sub-pixels have spacers on the second side in the second direction, some first color sub-pixels have spacers on the third side in the second direction, and some first color sub-pixels have 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 misaligned in one orientation, causing some spacers to fail to effectively support the FMM, the spacers in other orientations can still effectively support the FMM, thereby preventing the FMM from scratching the film structure of the multiple sub-pixels on the display substrate and thus avoiding various defects.

[0069] In some examples, as shown in Figure 1, the length of the virtual edge containing the first vertex P11 and the second vertex P12 of the first virtual quadrilateral region A is greater than the dimension of N first color sub-pixels 120A in the direction of the extension of the virtual edge, where N is greater than or equal to 2. That is to say, the range or size of the first virtual quadrilateral region can be set according to actual needs.

[0070] In some examples, as shown in Figure 1, the first virtual quadrilateral region A is rectangular in shape. Therefore, the line connecting the first spacer 131 and the first color sub-pixel 120A near the first vertex P11 of the first virtual quadrilateral region A is perpendicular to the line connecting the second spacer 132 and the first color sub-pixel 120A near the second vertex P12 of the first virtual quadrilateral region A. Of course, embodiments of this disclosure include, but are not limited to, the shape of the first virtual quadrilateral region can also be other shapes.

[0071] In some examples, as shown in Figure 1, the display substrate 100 includes a second virtual quadrilateral region B. A first spacer 131 and a second spacer 132 are located at the fifth vertex P21 and the sixth vertex P22 of the second virtual quadrilateral region B, respectively. The fifth vertex P21 and the sixth vertex P22 are adjacent to each other or located at the two endpoints of the same edge of the second virtual quadrilateral region B. Two second color sub-pixels 120B are located at the two corners where the fifth vertex P21 and the sixth vertex P22 of the second virtual quadrilateral region B are located.

[0072] In the display substrate provided in this embodiment, since the fifth and sixth vertices of the second virtual quadrilateral region are respectively provided with a first spacer and a second spacer, and two second color sub-pixels are provided at the two corners where the fifth and sixth vertices are located, 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 a first spacer in the first direction, and the other is provided with a second spacer in the second direction. That is, 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 used to form the second color sub-pixel and the display substrate are misaligned in the first or second direction, causing one of the first and second spacers at the adjacent fifth and sixth vertices of the second virtual quadrilateral region to be unable to effectively support the FMM, since the displacement in the other direction is small, the other of the first and second 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.

[0073] In some examples, as shown in Figure 1, the shape of the second virtual quadrilateral region B is rectangular. Therefore, the line connecting the first spacer 131 and the second color sub-pixel 120B near the fifth vertex P21 of the second virtual quadrilateral region B is perpendicular to the line connecting the second spacer 132 and the second color sub-pixel 120B near the sixth vertex P22 of the second virtual quadrilateral region B. Of course, embodiments of this disclosure include, but are not limited to, this, and the shape of the second virtual quadrilateral region can also be other shapes.

[0074] In some examples, as shown in Figure 1, the length of the virtual edge containing the fifth vertex P21 and the sixth vertex P22 of the second virtual quadrilateral region B is greater than the dimension of N second color sub-pixels 120A in the direction of the virtual edge extension, where N is greater than or equal to 2. That is, the range or size of the second virtual quadrilateral region can be set according to actual needs.

[0075] In some examples, as shown in Figure 1, the display substrate 100 includes a third virtual quadrilateral region C. A first spacer 131 and a second spacer 132 are located at the seventh vertex P31 and the eighth vertex P32 of the third virtual quadrilateral region C, respectively. The seventh vertex P31 and the eighth vertex P32 are adjacent or are two endpoints on the same virtual edge of the third virtual quadrilateral region C. Two third color sub-pixels 120C are located at the two corners of the third virtual quadrilateral region C where the seventh vertex P31 and the eighth vertex P32 are located. It should be noted that the rectangular blocks shown in A, B, C, and D in Figure 1 are not actual structures, but schematically illustrate the range of the various virtual quadrilateral regions mentioned above; and the edges of the various virtual quadrilateral regions mentioned above are defined by the vertices or the centers of the spacers, not by the rectangular blocks shown in A, B, C, and D.

[0076] In the display substrate provided in this embodiment, since the adjacent seventh and eighth vertices of the third virtual quadrilateral region are respectively provided with a first spacer and a second spacer, and two second color sub-pixels are provided at the two corners where the seventh and eighth vertices are located, 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 a first spacer in the first direction, and the other is provided with a second spacer in the second direction. That is, 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 misaligned in the first or second direction, causing one of the first and second spacers of the adjacent seventh and eighth vertices of the third virtual quadrilateral region to be unable to effectively support the FMM, since the displacement in the other direction is small, the other of the first and second 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.

[0077] In some examples, as shown in Figure 1, the third virtual quadrilateral region C is rectangular. Therefore, the line connecting the first spacer 131 near the seventh vertex P31 of the third virtual quadrilateral region C and the third color sub-pixel 120C is perpendicular to the line connecting the second spacer 132 near the eighth vertex P32 of the third virtual quadrilateral region C and the third color sub-pixel 120C. Of course, embodiments of this disclosure include, but are not limited to, this shape; the shape of the third virtual quadrilateral region can also be other shapes.

[0078] In some examples, as shown in Figure 1, the length of the virtual edge containing the seventh vertex P31 and the eighth vertex P32 of the third virtual quadrilateral region C is greater than the dimension of N third color sub-pixels 120C in the direction of extension of the virtual edge, where N is greater than or equal to 2. That is, the range or size of the third virtual quadrilateral region can be set according to actual needs.

[0079] In some examples, as shown in Figure 1, the display substrate 100 may further include a fourth virtual quadrilateral region D. A first spacer 131 and a second spacer 132 are located at the ninth vertex P41 and the tenth vertex P42 of the fourth virtual quadrilateral region D, respectively. The ninth vertex P41 and the tenth vertex P42 are adjacent, or are two endpoints on the same virtual edge of the fourth virtual quadrilateral region D. 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 the rectangular blocks shown in A, B, C, and D in Figure 1 are not actual structures, but schematically illustrate the range of the various virtual quadrilateral regions mentioned above; and the edges of the various virtual quadrilateral regions mentioned above are defined by the vertices or the centers of the spacers, not by the rectangular blocks shown in A, B, C, and D.

[0080] In the display substrate provided in this embodiment, since the adjacent ninth and tenth vertices of the fourth virtual quadrilateral region are respectively provided with a first spacer and a second spacer, and two second color sub-pixels are provided at the two corners where the ninth and tenth vertices are located, 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 a first spacer in the first direction, and the other is provided with a second spacer in the second direction. That is, 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 used to form the third color sub-pixel and the display substrate are misaligned in the first or second direction, and one of the first and second spacers at the adjacent ninth and tenth vertices of the fourth virtual quadrilateral region cannot effectively support the FMM, since the displacement in the other direction is small, the other of the first and second 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.

[0081] In some examples, as shown in Figure 1, the fourth virtual quadrilateral region D is rectangular. Therefore, the line connecting the first spacer 131 and the second color sub-pixel 120B near the ninth vertex P41 of the fourth virtual quadrilateral region D is perpendicular to the line connecting the second spacer 132 and the second color sub-pixel 120B near the tenth vertex P42 of the fourth virtual quadrilateral region D. Of course, embodiments of this disclosure include, but are not limited to, this, and the shape of the fourth virtual quadrilateral region can also be other shapes.

[0082] In some examples, as shown in Figure 1, the length of the virtual edge containing the ninth vertex P41 and the tenth vertex P42 of the fourth virtual quadrilateral region D is greater than the dimension of N second color sub-pixels 120B in the extension direction of the virtual edge, where N is greater than or equal to 2. That is, the range or size of the fourth virtual quadrilateral region can be set according to actual needs.

[0083] In some examples, as shown in Figure 1, the first virtual quadrilateral region A, the second virtual quadrilateral region B, the third virtual quadrilateral region C, and the fourth virtual quadrilateral region D can constitute a larger virtual quadrilateral region.

[0084] In some examples, as shown in Figure 1, the first virtual quadrilateral region A and the second virtual quadrilateral region B share an edge; the second virtual quadrilateral region B and the third virtual quadrilateral region C share an edge; and the third virtual quadrilateral region C and the fourth virtual quadrilateral region D share an edge.

[0085] In some examples, as shown in Figure 1, each spacer 130 is arranged adjacent to four sub-pixels 120, and there are no other sub-pixels between the spacer 130 and the adjacent sub-pixels 120. Thus, the spacer can be placed within the area enclosed by the four sub-pixels, thereby making full use of the space on the display substrate.

[0086] In some examples, as shown in Figure 1, each spacer 130 is located between the corners of four adjacent sub-pixels 120, rather than between the edges of adjacent sub-pixels.

[0087] In some examples, as shown in FIG1, the display substrate 100 further 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.

[0088] In the display substrate provided in this example, the display substrate 100 can employ tandem light-emitting technology, meaning that the light-emitting layer 122 of each sub-pixel 120 can include multiple light-emitting sub-layers and charge-generating layers between the light-emitting sub-layers. Therefore, the display substrate 100 can have high brightness and long lifespan. When the display substrate 100 employs tandem light-emitting technology, the light-emitting layer has a large thickness and height. On the other hand, the pixel isolation structure 150 can isolate the charge-generating layers of adjacent sub-pixels 120 to prevent crosstalk. Each spacer 130 is located in the area between two first pixel isolation structures 151 and two second pixel isolation structures 152. The size of the spacers is further limited, and the thickness of the light-emitting layer is also relatively large. Therefore, when the FMM is insufficiently supported, it is easier to scratch the light-emitting layer 122, causing various defects. In this case, by adopting the spacer design provided in the embodiments of this 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 using the stacked light-emitting technology, thereby avoiding various defects and achieving both high display performance and high yield.

[0089] In some examples, as shown in FIG1, the display substrate 100 includes a substrate 110, a plurality of sub-pixels 120, and a plurality of spacers 130; the plurality of sub-pixels 120 are located on the 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 region between adjacent sub-pixels 120. The plurality of sub-pixels 120 includes a plurality of first sub-pixel rows 161 and a plurality of first sub-pixel columns 171, each first sub-pixel row 161 including a plurality of first color sub-pixels 120A and a plurality of third color sub-pixels 120C alternately arranged along a first direction, and each first sub-pixel column 171 including 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 and second directions intersect. The aforementioned plurality of spacers 130 includes a first spacer 131 and a second spacer 132.

[0090] As shown in Figure 1, the plurality of first sub-pixel rows 161 include a plurality of first pixel spacer rows 1615, each first pixel spacer row 1615 including a first spacer 131, located between adjacent first color sub-pixels 120A and third color sub-pixels 120C in a first direction; the plurality of first sub-pixel columns 171 include a plurality of first pixel spacer columns 1715, each first pixel spacer column 1715 including a second spacer 132, located between adjacent first color sub-pixels 120A and third color sub-pixels 120C in a second direction.

[0091] In the display substrate provided in this embodiment, each row 1615 of first pixel spacers includes a first spacer 131 located between adjacent first color sub-pixels 120A and third color sub-pixels 120C in a first direction, and each column 1715 of first pixel spacers includes a second spacer 132 located between adjacent first color sub-pixels 120A and third color sub-pixels 120C in a second direction. For each first color sub-pixel, some first color sub-pixels are provided with first spacers in the first direction, and some first color sub-pixels are provided with second spacers in the second direction. When the FMM used to form the first color sub-pixel and the display substrate are misaligned in the first or second direction, causing one of the first and second spacers to fail to effectively support the FMM, since the displacement in the other direction is small, the other of the first and second spacers can still effectively support the FMM, thereby preventing the FMM from scraping the film structure of multiple sub-pixels on the display substrate, such as the organic light-emitting layer, and thus avoiding various defects.

[0092] Similarly, for the third color sub-pixel, some third color sub-pixels have a first spacer in the first direction, and some third color sub-pixels have a second spacer in the second direction. When the FMM used to form the third color sub-pixel and the display substrate are misaligned in the first or second direction, causing one of the first and second spacers to fail to effectively support the FMM, the other spacer can still effectively support the FMM because the displacement in the other direction is small. This prevents the FMM from scraping against the film structure of multiple sub-pixels on the display substrate, such as the organic light-emitting layer, and thus avoids various defects.

[0093] For example, the first direction described above is perpendicular to the second direction. Of course, embodiments of this disclosure include, but are not limited to, the first and second directions may not be perpendicular.

[0094] In some examples, as shown in FIG1, the plurality of first pixel spacer rows 1615 are uniformly distributed in the plurality of first sub-pixel rows 161. For example, one first pixel spacer row 1615 is provided for every four first sub-pixel rows 161. Of course, embodiments of this disclosure include, but are not limited to, this.

[0095] In some examples, as shown in FIG1, the plurality of first pixel spacer columns 1715 are uniformly distributed in the plurality of first sub-pixel columns 171. For example, one first pixel spacer column 1715 is provided for every four first sub-pixel columns 171. Of course, embodiments of this disclosure include, but are not limited to, this.

[0096] In some examples, as shown in Figure 1, the first spacers 131 in two adjacent rows 1615 of first pixel spacers in the second direction are aligned in the second direction, that is, the corresponding first spacers 131 in two adjacent rows 1615 of first pixel spacers in the second direction are located on a straight line extending along the second direction.

[0097] In some examples, as shown in FIG1, the second spacers 132 in adjacent first pixel spacer columns 1715 in the first direction are aligned in the first direction, that is, the corresponding second spacers 132 in adjacent first pixel spacer columns 1715 in the first direction are located on a straight line extending along the first direction.

[0098] In some examples, as shown in Figure 1, the plurality of subpixels 120 include a plurality of second subpixel rows 162 and a plurality of second subpixel columns 172. Each second subpixel row 162 includes a plurality of second color subpixels 120B alternately arranged along a first direction, and each second subpixel column 172 includes a plurality of second color subpixels 120B alternately arranged along a second direction. The plurality of second subpixel rows 162 are arranged along the second direction, and the plurality of second subpixel columns 172 are arranged along the first direction.

[0099] In some examples, as shown in Figure 1, a plurality of second subpixel rows 162 include a plurality of second pixel spacer rows 1625, each second pixel spacer row 1625 including a second spacer 132 located between adjacent second color subpixels 120B in a first direction, and a plurality of second subpixel columns 172 include a plurality of second pixel spacer columns 1725, each second pixel spacer column 1725 including a first spacer 131 located between adjacent second color subpixels 120B in a second direction.

[0100] In the display substrate provided in this embodiment, each row 1625 of second pixel spacers includes a second spacer 132 located between adjacent second color sub-pixels 120B in the first direction, and each column 1725 of second pixel spacers includes a first spacer 131 located between adjacent second color sub-pixels 120B in the second direction. For each second color sub-pixel, some second color sub-pixels are provided with second spacers in the first direction, and some second color sub-pixels are provided with first spacers in the second direction. When the FMM used to form the second color sub-pixel and the display substrate are misaligned in the first or second direction, causing one of the first and second spacers to fail to effectively support the FMM, since the displacement in the other direction is small, the other of the first and second spacers can still effectively support the FMM, thereby preventing the FMM from scraping the film structure of multiple sub-pixels on the display substrate, such as the organic light-emitting layer, and thus avoiding various defects.

[0101] In some examples, as shown in Figure 1, multiple first subpixel rows 161 and multiple second subpixel rows 162 are alternately arranged in a second direction, and multiple first subpixel columns 171 and multiple second subpixel columns 172 are alternately arranged in a first direction.

[0102] In some examples, as shown in FIG1, the plurality of second pixel spacer rows 1625 are evenly distributed in the plurality of second sub-pixel rows 162. For example, one second pixel spacer row 1625 is provided for every four second sub-pixel rows 162. Of course, embodiments of this disclosure include, but are not limited to, this.

[0103] In some examples, as shown in FIG1, the plurality of second pixel spacer columns 1725 are evenly distributed in the plurality of second sub-pixel columns 172. For example, one second pixel spacer column 1725 is provided for every four second sub-pixel columns 172. Of course, embodiments of this disclosure include, but are not limited to, this.

[0104] In some examples, as shown in Figure 1, the second spacers 132 in two adjacent rows 1625 of second pixel spacers in the second direction are aligned in the second direction, that is, the corresponding second spacers 132 in two adjacent rows 1625 of second pixel spacers in the second direction are located on a straight line extending along the second direction.

[0105] In some examples, as shown in FIG1, the first spacers 131 in adjacent rows 1725 of the second pixel spacers in the first direction are aligned in the first direction, that is, the corresponding first spacers 131 in adjacent rows 1725 of the second pixel spacers in the first direction are located on a straight line extending along the first direction. FIG2 is a planar schematic diagram of another display substrate provided in an embodiment of the present disclosure. As shown in FIG2, the display substrate 100 includes: a substrate 110; a plurality of sub-pixels 120 located on the substrate 110; and a plurality of spacers 130, each spacer 130 being located in the spacing region between adjacent sub-pixels 120. The plurality of sub-pixels 120 includes 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, multiple spacers 130 can be used to support the ultrafine 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 ultrafine metal masks.

[0106] For example, the first color mentioned above can be red, with a wavelength range of 620-750 nanometers; the second color can be green, with a wavelength range of 495-570 nanometers; and the third color can be blue, with a wavelength range of 450-495 nanometers.

[0107] As shown in Figure 2, the display substrate 100 includes a first virtual quadrilateral region A. Multiple 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 opposite ends of the same edge of the first virtual quadrilateral region A. Two first color sub-pixels 120A are located at the two corners where the first vertex P11 and the second vertex P12 of the first virtual quadrilateral region A are located.

[0108] In the display substrate provided in this embodiment, since the adjacent first vertices and second vertices of the first virtual quadrilateral region are respectively provided with first spacers and second spacers, and two first color sub-pixels are provided at the two corners where the first and second vertices are located, 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, 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 misaligned in the first or second direction, and one of the first spacers and second spacers of the adjacent first and second vertices of the first virtual quadrilateral region cannot effectively support the FMM, since the displacement in the other direction is small, the other of the first spacers and second 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.

[0109] In some examples, as shown in Figure 2, multiple 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. 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 first pixel group 141 and the second pixel group 142 have the same type and number of sub-pixels, but their arrangement is different.

[0110] In some examples, as shown in Figure 2, the first spacer 131 is located within 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 within 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. That is, the first spacer 131 and the second spacer 132 are in different environments.

[0111] 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 used to form the first color sub-pixel and the display substrate are misaligned in the first or second direction, causing one of the first and second spacers to fail to effectively support the FMM, since the displacement in the other direction is small, the other of the first and second spacers can still effectively support the FMM, thereby preventing the FMM from scratching the film structure of multiple sub-pixels on the display substrate, and thus avoiding various defects.

[0112] 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, while 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 used to form the third color sub-pixel and the display substrate are misaligned in the first or second direction, causing one of the first and second spacers to fail to effectively support the FMM, since the displacement in the other direction is small, the other of the first and second spacers can still effectively support the FMM, thereby preventing the FMM from scratching the film structure of multiple sub-pixels on the display substrate, and thus avoiding various defects.

[0113] 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, while 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 used to form the second color sub-pixel and the display substrate are misaligned in the first or second direction, causing one of the first and second spacers to fail to effectively support the FMM, since the displacement in the other direction is small, the other of the first and second spacers can still effectively support the FMM, thereby preventing the FMM from scratching the film structure of multiple sub-pixels on the display substrate, and thus avoiding various defects.

[0114] In some examples, as shown in Figure 2, the first spacer 131 and the second spacer 132 have different sizes. 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, and the space where the first spacer 131 is located is larger, the size of the first spacer 131 can be set to be larger than the size of the second spacer 132. This allows the first spacer 131 to make full use of the spacing area within the first pixel group 141 and allows the first spacer 131 to support the FMM over a larger area, thereby further reducing the risk of the FMM scratching the film structure of multiple sub-pixels on the display substrate.

[0115] In some examples, as shown in Figure 2, 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 in different environments, the first spacer 131 and the second spacer 132 can be set to specific shapes according to their environments, thereby making full use of the spacing areas in the first pixel group 141 and the second pixel group 142.

[0116] For example, as shown in Figure 2, the first spacer 131 is rectangular in shape, and the second spacer 132 is circular in shape. Of course, embodiments of this disclosure include, but are not limited to, these shapes, and the shapes of the first and second spacers can be set according to actual conditions. It should be noted that the shape of the spacers mentioned above refers to the planar shape of the spacers, that is, the shape of the orthographic projection of the spacers onto the substrate.

[0117] In some examples, as shown in Figure 2, 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 located at the third vertex P13 and the fourth vertex P14 of the first virtual quadrilateral region A, respectively. The third vertex P13 and the fourth vertex P14 are adjacent, or the third vertex P13 and the fourth vertex P14 are located at the two endpoints of an edge of the first virtual quadrilateral region A. It should be noted that the third vertex P13 and the fourth vertex P14 are different vertices from the first vertex P11 and the second vertex P12.

[0118] In some examples, as shown in Figure 2, two first color sub-pixels 120A are located at the two corners of the third vertex P13 and the fourth vertex P14 of the first virtual quadrilateral region A. Since the adjacent first and second vertices of the first virtual quadrilateral region are respectively provided with first and second spacers, and the adjacent third and fourth vertices are respectively provided with third and fourth spacers, and four first color sub-pixels are provided at the four corners of the first, second, third, and fourth vertices of the first virtual quadrilateral region, for the four first color sub-pixels provided at the four corners of the first, second, third, and fourth vertices, the first of these four first color sub-pixels has a first spacer on the first side in the first direction, the second of these four first color sub-pixels has a third spacer on the second side in the first direction, the third of these four first color sub-pixels has a second spacer on the third side in the second direction, and the fourth of these four first color sub-pixels has a fourth spacer on the fourth side in the second direction. When the FMM used to form the first color sub-pixel and the display substrate shift in a first direction towards a first side, causing the first spacer to fail to effectively support the FMM, the second, third, and fourth spacers can still effectively support the FMM, thereby preventing the FMM from scraping against 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 shifting occurs in other directions, the FMM can also be prevented from scraping against the film structure of multiple sub-pixels on the display substrate, which will not be elaborated further here.

[0119] In some examples, as shown in Figure 2, the plurality of sub-pixels 120 includes a third pixel group 143 and a fourth pixel group 144. The arrangement of sub-pixels 120 in the fourth pixel group 144 is mirror-symmetrical with respect to the arrangement of sub-pixels 120 in the second pixel group 142 with respect to a first virtual straight line extending along a first direction. The arrangement of sub-pixels 120 in the third pixel group 143 is mirror-symmetrical with respect to the arrangement of sub-pixels 120 in the first pixel group 141 with respect to a second virtual straight line extending along a second direction. That is, the third pixel group 143 includes a third color sub-pixel 120C and a first color sub-pixel 120A arranged along the first direction and two second color sub-pixels 120B arranged along the second direction. The fourth pixel group 144 includes two second color sub-pixels 120B arranged along the first direction and a third color sub-pixel 120C and a first color sub-pixel 120A arranged along the second direction.

[0120] In some examples, as shown in Figure 2, the third spacer 133 is located in the interval region 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 interval region 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.

[0121] In the display substrate provided in this example, since the first spacer, second spacer, third spacer, and fourth spacer are located in the first pixel group, second pixel group, third pixel group, and fourth pixel group, respectively, for the multiple first color sub-pixels on the display substrate, there are four possible orientations where spacers are provided. That is, some first color sub-pixels have spacers on the first side in the first direction, some first color sub-pixels have spacers on the second side in the second direction, some first color sub-pixels have spacers on the third side in the second direction, and some first color sub-pixels have 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 misaligned in one orientation, causing some spacers to fail to effectively support the FMM, the spacers in other orientations can still effectively support the FMM, thereby preventing the FMM from scratching the film structure of the multiple sub-pixels on the display substrate and thus avoiding various defects.

[0122] In some examples, as shown in Figure 2, the third spacer 133 and the fourth spacer 134 have different sizes. 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 in different environments, and the space where the third spacer 133 is located is larger, the size of the third spacer 133 can be set to be larger than the size of the fourth spacer 134. This allows the third spacer 133 to make full use of the spacing area within the third pixel group 143 and allows the third spacer 133 to support the FMM over a larger area, thereby further reducing the risk of the FMM scratching the film structure of multiple sub-pixels on the display substrate.

[0123] In some examples, as shown in Figure 2, the first spacer 131 and the third spacer 133 are approximately equal in size, and the second spacer 132 and the fourth spacer 134 are approximately equal in size.

[0124] In some examples, as shown in Figure 2, 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 in different environments, the third spacer 133 and the fourth spacer 134 can be set to specific shapes according to their environments, thereby making full use of the spacing areas in the third pixel group 143 and the fourth pixel group 144.

[0125] For example, as shown in Figure 2, the third spacer 133 is rectangular in shape, and the fourth spacer 134 is circular in shape. Of course, the embodiments of this disclosure include, but are not limited to, the shapes of the third and fourth spacers can be set according to actual conditions.

[0126] In some examples, based on the embodiment shown in FIG2, the display substrate may include only the larger first spacer and third spacer, without the aforementioned second spacer and fourth spacer, thereby reducing the density of the spacers.

[0127] In some examples, as shown in Figure 2, 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. A 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 the relevant description in Figure 1, and will not be repeated here.

[0128] In some examples, as shown in Figure 2, each spacer 130 is arranged adjacent to four sub-pixels 120, and there are no other sub-pixels between the spacer 130 and the adjacent sub-pixels 120. Thus, the spacer can be placed within the area enclosed by the four sub-pixels, thereby making full use of the space on the display substrate.

[0129] In some examples, as shown in Figure 2, each spacer 130 is located between the corners of four adjacent sub-pixels 120, rather than between the edges of adjacent sub-pixels.

[0130] In some examples, as shown in FIG2, the display substrate 100 further 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.

[0131] In the display substrate provided in this example, the display substrate 100 can employ tandem light-emitting technology, meaning that the light-emitting layer 122 of each sub-pixel 120 can include multiple light-emitting sub-layers and charge-generating layers between the light-emitting sub-layers. Therefore, the display substrate 100 can have high brightness and long lifespan. When the display substrate 100 employs tandem light-emitting technology, the light-emitting layer has a large thickness and height. On the other hand, the pixel isolation structure 150 can isolate the charge-generating layers of adjacent sub-pixels 120 to prevent crosstalk. Each spacer 130 is located in the area between two first pixel isolation structures 151 and two second pixel isolation structures 152. The size of the spacers is further limited, and the thickness of the light-emitting layer is also relatively large. Therefore, when the FMM is insufficiently supported, it is easier to scratch the light-emitting layer 122, causing various defects. In this case, by adopting the spacer design provided in the embodiments of this 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 using the stacked light-emitting technology, thereby avoiding various defects and achieving both high display performance and high yield.

[0132] Figure 3A is a partially enlarged schematic diagram of a display substrate provided in an embodiment of the present disclosure; Figure 3B is a partially enlarged schematic diagram of another display substrate provided in an embodiment of the present disclosure.

[0133] As shown in Figure 3A, the display substrate 100 includes: a substrate 110; a plurality of sub-pixels 120 located on the substrate 110; and a plurality of spacers 130, each spacer 130 being located in a spacing region between adjacent sub-pixels 120. The plurality of sub-pixels 120 includes 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. The pixel opening 123 is located within a pixel defining layer, and the light-emitting layer 122 is disposed 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 can be used to support an ultrafine metal mask (FMM).

[0134] As shown in Figure 3A, when the FMM and the display substrate 100 misalign in the second direction Y, the spacer 130 may come into contact with the opening edge of the FMM, causing friction and resulting in particulate matter and sub-pixel light emission. On the other hand, when the misalignment distance between the FMM and the display substrate 100 in the second direction Y is large, the spacer 130 may fall into the opening edge of the FMM, failing to support the FMM, causing the FMM to scrape against the light-emitting layer 122, resulting in various defects.

[0135] As shown in Figure 3A, the display substrate 100 can employ tandem light-emitting technology, meaning that the light-emitting layer 122 of each sub-pixel 120 can include multiple light-emitting sub-layers and charge-generating layers between them. This allows the display substrate 100 to have higher brightness and longer lifespan. When the display substrate 100 employs tandem light-emitting technology, the light-emitting layer has a larger thickness and greater height. Furthermore, to isolate the charge-generating layers of adjacent sub-pixels 120 and prevent crosstalk, the display substrate 100 also includes a pixel isolation structure 150. This further restricts the size of the spacer, and the thickness of the light-emitting layer is still relatively large. Therefore, when the FMM (Film Mesh Mirror) is insufficiently supported, it is more likely to scratch the light-emitting layer 122, causing various defects. In this case, by adopting the spacer design provided in the embodiments of this disclosure, the display substrate, while employing tandem light-emitting technology, can still avoid the FMM scratching the film structure of multiple sub-pixels on the display substrate, such as the organic light-emitting layer, thereby avoiding various defects and achieving both high display performance and high yield.

[0136] As shown in Figure 3B, the spacer 130 used in the display substrate 100 is larger than the spacer 130 in Figure 3A. Therefore, the spacer can support the FMM over a larger area, thereby further reducing the risk of the FMM scratching the film structure of multiple sub-pixels on the display substrate.

[0137] Figure 4 is a schematic diagram of another display substrate provided in an embodiment of the present disclosure. As shown in Figure 4, the display substrate 100 includes: a substrate 110; a plurality of sub-pixels 120 located on the substrate 110; and a plurality of spacers 130, each spacer 130 being located in the spacing region between adjacent sub-pixels 120. The plurality of sub-pixels 120 includes 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 ultrafine 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 typically formed using different ultrafine metal masks.

[0138] For example, the first color mentioned above can be red, with a wavelength range of 620-750 nanometers; the second color can be green, with a wavelength range of 495-570 nanometers; and the third color can be blue, with a wavelength range of 450-495 nanometers.

[0139] As shown in Figure 4, the display substrate 100 includes a first virtual quadrilateral region A. Multiple 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 opposite ends of the same edge of the first virtual quadrilateral region A. Two first color sub-pixels 120A are located at the two corners where the first vertex P11 and the second vertex P12 of the first virtual quadrilateral region A are located.

[0140] As shown in Figure 4, the plurality of spacers 130 also includes a third spacer 133 and a fourth spacer 134. A first spacer 133 and a second spacer 134 are located at the third vertex P13 and the fourth vertex P14 of the first virtual quadrilateral region A, respectively. The third vertex P13 and the fourth vertex P14 are adjacent, or the third vertex P13 and the fourth vertex P14 are located at the two ends of the same edge of the first virtual quadrilateral region A. Two second color sub-pixels 120B are located at the two corners where the third vertex P13 and the fourth vertex P14 of the first virtual quadrilateral region A are located, respectively.

[0141] In the display substrate provided in this embodiment, since the adjacent first vertices and second vertices of the first virtual quadrilateral region are respectively provided with first spacers and second spacers, and two first color sub-pixels are provided at the two corners where the first and second vertices are located, 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, 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 misaligned in the first or second direction, and one of the first spacers and second spacers of the adjacent first and second vertices of the first virtual quadrilateral region cannot effectively support the FMM, since the displacement in the other direction is small, the other of the first spacers and second 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.

[0142] Similarly, since the adjacent third and fourth vertices of the first virtual quadrilateral region are respectively provided with third and fourth spacers, 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 these two second color sub-pixels is provided with a third spacer in the first direction, and the other is provided with a fourth spacer in the second direction. That is, one of these 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 used to form the second color sub-pixels and the display substrate are misaligned in the first or second direction, causing one of the third and fourth spacers at the adjacent third and fourth vertices of the first virtual quadrilateral region to be unable to effectively support the FMM, since the displacement in the other direction is small, the other of the third and fourth 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.

[0143] In summary, in the display substrate shown in Figure 4, the two opposite edges of the first virtual quadrilateral region A are respectively provided with sub-pixels of two colors. Therefore, the spacers at the four vertices of the first virtual quadrilateral region A can effectively support the FMM of the two color sub-pixels.

[0144] In some examples, as shown in Figure 4, 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 sub-pixels 120 in the fourth pixel group 144 is mirror-symmetric to the arrangement of 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 sub-pixels 120 in the third pixel group 143 is mirror-symmetric to the arrangement of sub-pixels 120 in the first pixel group 141 with respect to a second virtual straight line extending along the second direction. In other words, the third pixel group 143 includes a third-color sub-pixel 120C and a first-color sub-pixel 120A arranged along the first direction, and two second-color sub-pixels 120B arranged along the second direction. The fourth pixel group 144 includes two second-color sub-pixels 120B arranged along the first direction, and a third-color sub-pixel 120C and a first-color sub-pixel 120A arranged along the second direction. It can be seen that the first pixel group 141, the second pixel group 142, the third pixel group 143, and the fourth pixel group 144 have the same type and number of sub-pixels, but different arrangement methods.

[0145] In some examples, as shown in Figure 4, the first spacer 131 is located within the interval region 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 within the interval region 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 within the interval region 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 within the interval region 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.

[0146] In some examples, as shown in Figure 4, the first vertex P11 and the third vertex P13 of the first virtual quadrilateral region A are adjacent.

[0147] In some examples, as shown in Figure 4, the first virtual quadrilateral region A is a parallelogram.

[0148] In some examples, as shown in Figure 4, the length of the virtual edge containing the first vertex P11 and the second vertex P12 of the first virtual quadrilateral region A is greater than the dimension of N first color sub-pixels 120A in the direction of extension of the virtual edge, where N is greater than or equal to 2. That is to say, the range or size of the first virtual quadrilateral region can be set according to actual needs.

[0149] In some examples, as shown in Figure 4, the display substrate 100 includes a second virtual quadrilateral region B. A first spacer 131 and a second spacer 132 are located at the fifth vertex P21 and the sixth vertex P22 of the second virtual quadrilateral region B, respectively. The fifth vertex P21 and the sixth vertex P22 are adjacent to each other or located at the two endpoints of the same edge of the second virtual quadrilateral region B. Two second color sub-pixels 120B are located at the two corners where the fifth vertex P21 and the sixth vertex P22 of the second virtual quadrilateral region B are located.

[0150] In the display substrate provided in this embodiment, since the fifth and sixth vertices of the second virtual quadrilateral region are respectively provided with a first spacer and a second spacer, and two second color sub-pixels are provided at the two corners where the fifth and sixth vertices are located, 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 a first spacer in the first direction, and the other is provided with a second spacer in the second direction. That is, 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 used to form the second color sub-pixel and the display substrate are misaligned in the first or second direction, causing one of the first and second spacers at the adjacent fifth and sixth vertices of the second virtual quadrilateral region to be unable to effectively support the FMM, since the displacement in the other direction is small, the other of the first and second 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.

[0151] In some examples, as shown in Figure 4, the shape of the second virtual quadrilateral region B is a parallelogram. Two second-color sub-pixels 120B are set at the corners where the other two vertices of this second virtual quadrilateral region B are located.

[0152] In some examples, as shown in Figure 4, the display substrate 100 includes a third virtual quadrilateral region C. A first spacer 131 and a second spacer 132 are located at the seventh vertex P31 and the eighth vertex P32 of the third virtual quadrilateral region C, respectively. The seventh vertex P31 and the eighth vertex P32 are adjacent or are two endpoints on the same virtual edge of the third virtual quadrilateral region C. Two third color sub-pixels 120C are located at the two corners of the third virtual quadrilateral region C where the seventh vertex P31 and the eighth vertex P32 are located. It should be noted that the rectangular blocks shown in A, B, C, and D in Figure 4 are not actual structures, but schematically illustrate the range of the various virtual quadrilateral regions mentioned above; and the edges of the various virtual quadrilateral regions mentioned above are defined by the vertices or the centers of the spacers, not by the rectangular blocks shown in A, B, C, and D.

[0153] In the display substrate provided in this embodiment, since the adjacent seventh and eighth vertices of the third virtual quadrilateral region are respectively provided with a first spacer and a second spacer, and two second color sub-pixels are provided at the two corners where the seventh and eighth vertices are located, 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 a first spacer in the first direction, and the other is provided with a second spacer in the second direction. That is, 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 misaligned in the first or second direction, causing one of the first and second spacers of the adjacent seventh and eighth vertices of the third virtual quadrilateral region to be unable to effectively support the FMM, since the displacement in the other direction is small, the other of the first and second 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.

[0154] In some examples, as shown in Figure 4, the third virtual quadrilateral region C is a parallelogram. Two third color sub-pixels 120C are set at the corners where the other two vertices of the second virtual quadrilateral region B are located.

[0155] In some examples, as shown in Figure 4, the length of the virtual edge containing the seventh vertex P31 and the eighth vertex P32 of the third virtual quadrilateral region C is greater than the dimension of N third color sub-pixels 120C in the direction of extension of the virtual edge, where N is greater than or equal to 2. That is, the range or size of the third virtual quadrilateral region can be set according to actual needs.

[0156] In some examples, as shown in Figure 4, the display substrate 100 may further include a fourth virtual quadrilateral region D. A first spacer 131 and a second spacer 132 are located at the ninth vertex P41 and the tenth vertex P42 of the fourth virtual quadrilateral region D, respectively. The ninth vertex P41 and the tenth vertex P42 are adjacent, or are two endpoints on the same virtual edge of the fourth virtual quadrilateral region D. 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 the rectangular blocks shown in A, B, C, and D in Figure 4 are not actual structures, but schematically illustrate the range of the various virtual quadrilateral regions mentioned above; and the edges of the various virtual quadrilateral regions mentioned above are defined by the vertices or the centers of the spacers, not by the rectangular blocks shown in A, B, C, and D.

[0157] In the display substrate provided in this embodiment, since the adjacent ninth and tenth vertices of the fourth virtual quadrilateral region are respectively provided with a first spacer and a second spacer, and two second color sub-pixels are provided at the two corners where the ninth and tenth vertices are located, 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 a first spacer in the first direction, and the other is provided with a second spacer in the second direction. That is, 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 used to form the third color sub-pixel and the display substrate are misaligned in the first or second direction, and one of the first and second spacers at the adjacent ninth and tenth vertices of the fourth virtual quadrilateral region cannot effectively support the FMM, since the displacement in the other direction is small, the other of the first and second 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.

[0158] In some examples, as shown in Figure 4, the fourth virtual quadrilateral region D is a parallelogram. Two first-color sub-pixels 120A are set at the corners where the other two vertices of this fourth virtual quadrilateral region D are located.

[0159] In some examples, as shown in Figure 4, each spacer 130 is arranged adjacent to four sub-pixels 120, and there are no other sub-pixels between the spacer 130 and the adjacent sub-pixels 120. Thus, the spacer can be placed within the area enclosed by the four sub-pixels, thereby making full use of the space on the display substrate.

[0160] In some examples, as shown in Figure 4, each spacer 130 is located between the corners of four adjacent sub-pixels 120, rather than between the edges of adjacent sub-pixels.

[0161] In some examples, as shown in FIG4, the display substrate 100 includes a substrate 110, a plurality of sub-pixels 120, and a plurality of spacers 130; the plurality of sub-pixels 120 are located on the 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 region between adjacent sub-pixels 120. The plurality of sub-pixels 120 includes a plurality of first sub-pixel rows 161 and a plurality of first sub-pixel columns 171, each first sub-pixel row 161 including a plurality of first color sub-pixels 120A and a plurality of third color sub-pixels 120C alternately arranged along a first direction, and each first sub-pixel column 171 including 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 and second directions intersect. The aforementioned plurality of spacers 130 includes a first spacer 131 and a second spacer 132.

[0162] As shown in Figure 4, the plurality of first sub-pixel rows 161 include a plurality of first pixel spacer rows 1615, each first pixel spacer row 1615 including a first spacer 131, located between adjacent first color sub-pixels 120A and third color sub-pixels 120C in the first direction; the plurality of first sub-pixel columns 171 include a plurality of first pixel spacer columns 1715, each first pixel spacer column 1715 including a second spacer 132, located between adjacent first color sub-pixels 120A and third color sub-pixels 120C in the second direction.

[0163] In the display substrate provided in this embodiment, each row 1615 of first pixel spacers includes a first spacer 131 located between adjacent first color sub-pixels 120A and third color sub-pixels 120C in a first direction, and each column 1715 of first pixel spacers includes a second spacer 132 located between adjacent first color sub-pixels 120A and third color sub-pixels 120C in a second direction. For each first color sub-pixel, some first color sub-pixels are provided with first spacers in the first direction, and some first color sub-pixels are provided with second spacers in the second direction. When the FMM used to form the first color sub-pixel and the display substrate are misaligned in the first or second direction, causing one of the first and second spacers to fail to effectively support the FMM, since the displacement in the other direction is small, the other of the first and second spacers can still effectively support the FMM, thereby preventing the FMM from scraping the film structure of multiple sub-pixels on the display substrate, such as the organic light-emitting layer, and thus avoiding various defects.

[0164] Similarly, for the third color sub-pixel, some third color sub-pixels have a first spacer in the first direction, and some third color sub-pixels have a second spacer in the second direction. When the FMM used to form the third color sub-pixel and the display substrate are misaligned in the first or second direction, causing one of the first and second spacers to fail to effectively support the FMM, the other spacer can still effectively support the FMM because the displacement in the other direction is small. This prevents the FMM from scraping against the film structure of multiple sub-pixels on the display substrate, such as the organic light-emitting layer, and thus avoids various defects.

[0165] For example, the first direction described above is perpendicular to the second direction. Of course, embodiments of this disclosure include, but are not limited to, the first and second directions may not be perpendicular.

[0166] In some examples, as shown in Figure 4, the multiple first pixel spacer rows 1615 are unevenly distributed among the multiple first sub-pixel rows 161. For example, two adjacent first pixel spacer rows 1615 are directly adjacent, while other two adjacent first pixel spacer rows 1615 are spaced apart by one first sub-pixel row 161. Therefore, the display substrate can further reduce the risk of scratches.

[0167] In some examples, as shown in Figure 4, the multiple first pixel spacer columns 1715 are unevenly distributed among the multiple first sub-pixel columns 171. For example, two adjacent first pixel spacer columns 1715 are spaced apart by one first sub-pixel column 171, while other two adjacent first pixel spacer columns 1715 are directly adjacent. Therefore, the display substrate can further reduce the risk of scratches.

[0168] In some examples, as shown in Figure 4, the first spacers 131 in two adjacent rows 1615 of first pixel spacers in the second direction are misaligned, that is, the corresponding first spacers 131 in two adjacent rows 1615 of first pixel spacers in the second direction are not located on the same straight line extending along the second direction.

[0169] In some examples, as shown in FIG4, the second spacers 132 in adjacent columns of first pixel spacers 1715 in the first direction are misaligned, that is, the corresponding second spacers 132 in adjacent columns of first pixel spacers 1715 in the first direction are not located on the same straight line extending along the first direction.

[0170] In some examples, as shown in Figure 4, the plurality of subpixels 120 include a plurality of second subpixel rows 162 and a plurality of second subpixel columns 172. Each second subpixel row 162 includes a plurality of second color subpixels 120B alternately arranged along a first direction, and each second subpixel column 172 includes a plurality of second color subpixels 120B alternately arranged along a second direction. The plurality of second subpixel rows 162 are arranged along the second direction, and the plurality of second subpixel columns 172 are arranged along the first direction.

[0171] In some examples, as shown in Figure 4, a plurality of second subpixel rows 162 include a plurality of second pixel spacer rows 1625, each second pixel spacer row 1625 including a second spacer 132 located between adjacent second color subpixels 120B in a first direction, and a plurality of second subpixel columns 172 include a plurality of second pixel spacer columns 1725, each second pixel spacer column 1725 including a first spacer 131 located between adjacent second color subpixels 120B in a second direction.

[0172] In the display substrate provided in this embodiment, each row 1625 of second pixel spacers includes a second spacer 132 located between adjacent second color sub-pixels 120B in the first direction, and each column 1725 of second pixel spacers includes a first spacer 131 located between adjacent second color sub-pixels 120B in the second direction. For each second color sub-pixel, some second color sub-pixels are provided with second spacers in the first direction, and some second color sub-pixels are provided with first spacers in the second direction. When the FMM used to form the second color sub-pixel and the display substrate are misaligned in the first or second direction, causing one of the first and second spacers to fail to effectively support the FMM, since the displacement in the other direction is small, the other of the first and second spacers can still effectively support the FMM, thereby preventing the FMM from scraping the film structure of multiple sub-pixels on the display substrate, such as the organic light-emitting layer, and thus avoiding various defects.

[0173] In some examples, as shown in Figure 4, multiple first subpixel rows 161 and multiple second subpixel rows 162 are alternately arranged in the second direction, and multiple first subpixel columns 171 and multiple second subpixel columns 172 are alternately arranged in the first direction.

[0174] In some examples, as shown in Figure 4, the multiple second pixel spacer rows 1625 are unevenly distributed within the multiple second sub-pixel rows 162. This further reduces the risk of scratches on the display substrate.

[0175] In some examples, as shown in Figure 4, the multiple second pixel spacer columns 1725 are unevenly distributed within the multiple second sub-pixel columns 172. This further reduces the risk of scratches on the display substrate.

[0176] In some examples, as shown in Figure 4, the second spacers 132 in two adjacent rows 1625 of second pixel spacers in the second direction are misaligned, that is, the corresponding second spacers 132 in two adjacent rows 1625 of second pixel spacers in the second direction are not located on the same straight line extending along the second direction.

[0177] In some examples, as shown in FIG4, the first spacers 131 in adjacent rows of second pixel spacers 1725 in the first direction are misaligned, that is, the corresponding first spacers 131 in adjacent rows of second pixel spacers 1725 in the first direction are not located on the same straight line extending along the first direction.

[0178] Figure 5 is a planar schematic diagram of another display substrate provided in an embodiment of the present disclosure. As shown in Figure 5, the display substrate 100 includes: a substrate 110; a plurality of sub-pixels 120 located on the substrate 110; and a plurality of spacers 130, each spacer 130 being located in the spacing region between adjacent sub-pixels 120. The plurality of sub-pixels 120 includes 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 ultrafine 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 typically formed using different ultrafine metal masks.

[0179] For example, the first color mentioned above can be red, with a wavelength range of 620-750 nanometers; the second color can be green, with a wavelength range of 495-570 nanometers; and the third color can be blue, with a wavelength range of 450-495 nanometers.

[0180] As shown in Figure 5, the display substrate 100 includes a first virtual quadrilateral region A, and a plurality of spacers 130 including a first spacer 131 and a second spacer 132; the first virtual quadrilateral region A is trapezoidal in shape; 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 on the same edge of the first virtual quadrilateral region A. The first virtual quadrilateral region A has two ends; a first spacer 131 and a second spacer 132 are located at the third vertex P13 and the fourth vertex P14 of the first virtual quadrilateral region A, respectively. The third vertex P13 and the fourth vertex P14 are adjacent, or the third vertex P13 and the fourth vertex P14 are located at the two ends of the same edge of the first virtual quadrilateral region A; four second color sub-pixels 120B are located at the two corners of the first vertex P11, the second vertex P12, the third vertex P13 and the fourth vertex P14 of the first virtual quadrilateral region A.

[0181] In the display substrate provided in this embodiment, since the first, second, third, and fourth vertices of the first virtual quadrilateral region are respectively provided with first spacers and second spacers, and four second color sub-pixels are provided at the two corners of these four vertices, spacers are provided in all four directions for these four second color sub-pixels. When the FMM used to form the second color sub-pixels and the display substrate are misaligned in the first or second direction, causing one of the four spacers to fail to effectively support the FMM, the other spacers can still effectively support the FMM, thereby preventing the FMM from scraping the film structure of multiple sub-pixels on the display substrate, such as the organic light-emitting layer, and thus avoiding various defects.

[0182] In some examples, as shown in Figure 5, multiple 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. 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 first pixel group 141 and the second pixel group 142 have the same type and number of sub-pixels, but their arrangement is different.

[0183] In some examples, as shown in FIG5, the first spacer 131 and the third spacer 133 are located in the interval region 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 interval region 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.

[0184] 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 used to form the first color sub-pixel and the display substrate are misaligned in the first or second direction, causing one of the first and second spacers to fail to effectively support the FMM, since the displacement in the other direction is small, the other of the first and second spacers can still effectively support the FMM, thereby preventing the FMM from scratching the film structure of multiple sub-pixels on the display substrate, and thus avoiding various defects.

[0185] 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, while 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 used to form the third color sub-pixel and the display substrate are misaligned in the first or second direction, causing one of the first and second spacers to fail to effectively support the FMM, since the displacement in the other direction is small, the other of the first and second spacers can still effectively support the FMM, thereby preventing the FMM from scratching the film structure of multiple sub-pixels on the display substrate, and thus avoiding various defects.

[0186] 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, while 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 used to form the second color sub-pixel and the display substrate are misaligned in the first or second direction, causing one of the first and second spacers to fail to effectively support the FMM, since the displacement in the other direction is small, the other of the first and second spacers can still effectively support the FMM, thereby preventing the FMM from scratching the film structure of multiple sub-pixels on the display substrate, and thus avoiding various defects.

[0187] Figure 6A is a cross-sectional view of one type of spacer; Figure 6B is a plan view of another type of spacer provided in an embodiment of this disclosure; Figure 6C is a cross-sectional view of another type of spacer provided in an embodiment of this disclosure along line AB in Figure 6B. As shown in Figure 6A, since spacers are typically formed from organic materials, the edges of the spacers are sloped, resulting in a lower height at the edges and weaker support. As shown in Figures 6B and 6C, the spacer 130 includes a plurality of spaced-apart sub-spacers 1305. Therefore, by setting the spacer as a plurality of spaced-apart sub-spacers 1305, the edges of the spacer 130 also have a higher height, thereby providing better support at the edges. It should be noted that the plurality of sub-spacers can share a base or be set independently. This disclosure does not impose any limitations on this. In addition, the spacers shown in Figures 6B and 6C can be applied to any of the spacers in Figures 1 to 5.

[0188] For example, as shown in FIG6B, the spacer 130 includes four sub-spacer portions 1305 spaced apart, the four sub-spacer portions 1305 forming a 2*2 matrix. Of course, embodiments of this disclosure include, but are not limited to, this. FIG7 is a schematic diagram of a display device provided in an embodiment of this disclosure. As shown in FIG7, the display device 500 includes the display substrate 100 provided in any of the above examples. Therefore, this display device can effectively prevent 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.

[0189] In some examples, the display device may employ stacked light emission technology, resulting in higher luminous brightness and a longer lifespan.

[0190] In some examples, the aforementioned display device can be any product or component with display function, such as a television, digital camera, mobile phone, watch, tablet computer, laptop computer, or navigator; this embodiment is not limited to this.

[0191] The following points need to be explained:

[0192] (1) The accompanying drawings of the embodiments of this disclosure only involve the structures involved in the embodiments of this disclosure, and other structures can be referred to the general design.

[0193] (2) Where there is no conflict, features of the same embodiment and different embodiments of this disclosure may be combined with each other.
