AI Technical Summary
During the manufacturing process of active matrix organic light-emitting diode (FMM) display devices, the relative positions of the ultra-fine metal mask and the display substrate are prone to misalignment, which can cause the spacers to fail to effectively support the FMM, resulting in the FMM scraping against the organic light-emitting layer and causing various defects.
First and second spacers are respectively set at the adjacent vertices of the first virtual quadrilateral region on the display substrate, and two adjacent color sub-pixels are adjacent to the spacers in different directions to ensure that when the FMM is misaligned, the spacer in the other direction can effectively support the FMM and avoid scratching the sub-pixel film structure.
This effectively avoids the FMM scratching the sub-pixel film structure on the display substrate, improving product yield and display quality.

[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] The display substrate and the display device are provided. The first and second vertices of the first virtual quadrilateral region are respectively provided with the first and second spacers, and the two corners where the first and second vertices are located are provided with two first color sub-pixels. For the two first color sub-pixels provided at the two corners where the first and second vertices are located, one of the two first color sub-pixels is provided with the first spacer in the first direction, and the other is provided with the second spacer in the second direction. That is, one of the two first color sub-pixels is adjacent to the first spacer in the first direction, and the other is adjacent to the second spacer in the second direction. When the FMM used to form the first color sub-pixel and the display substrate are misaligned in the first direction or the second direction, and one of the first and second spacers of the first and second vertices of the first virtual quadrilateral region cannot effectively support the FMM, since the displacement of the misalignment in the other direction is small, the other of the first and second spacers can still effectively support the FMM, thereby avoiding the FMM scratching the film layer structure, such as the organic light-emitting layer, of the plurality of sub-pixels on the display substrate, and further avoiding various defects.

[0046] In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments of the present disclosure. Based on the described embodiments of the present disclosure, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of protection of the present disclosure.
[0047] Unless otherwise defined, technical terms or scientific terms used in the present disclosure shall have the ordinary meaning understood by a person of ordinary skill in the art to which the present disclosure pertains. The terms "first", "second", and similar terms used in the present disclosure do not denote any order, quantity, or importance, but are used to distinguish different components. The terms "include", "contain", and similar terms mean that the elements or objects before the terms encompass the elements or objects listed after the terms and their equivalents, and do not exclude other elements or objects.
[0048] The terms "parallel," "perpendicular," and "same" as used in the embodiments of the present disclosure include the strict "parallel," "perpendicular," and "same" as well as "approximately parallel," "approximately perpendicular," and "approximately same" with a certain error, which, taking into account the measurement and the error related to the measurement of a specific value (for example, the limitation of the measurement system), represents the acceptable deviation range for the specific value determined by the person skilled in the art. For example, "approximately" can represent within one or more standard deviations, or within 10% or 5% of the value. In the following of the embodiments of the present disclosure, when the quantity of a component is not specifically indicated, it means that the component can be one or more, or can be understood as at least one. "At least one" means one or more, and "multiple" means at least two. "Same layer" in the embodiments of the present disclosure refers to the relationship between multiple film layers formed by the same material after the same step (for example, one patterning process). Here, "same layer" does not always mean that the thicknesses of the multiple film layers are the same or the heights of the multiple film layers in the cross-sectional view are the same.
[0049] In the manufacturing process of an active matrix organic light-emitting diode display device, an organic light-emitting layer is usually formed by an evaporation process using an extremely fine metal mask (FMM); in this process, a spacer (PS) needs to be arranged on the display substrate to support the FMM, so as to avoid the FMM from scratching the organic light-emitting layer on the display substrate and thus causing various defects. Therefore, the parameters such as the morphology, quantity, position, and density of the spacers need to be comprehensively considered in combination with the process requirements and the characteristics of different products, and a trade-off design is needed.
[0050] The inventors of the present application have noticed that in actual processes, the relative position of the FMM and the display substrate is prone to misalignment, and the spacers are usually placed in the same environment, resulting in insufficient margin of the FMM of the R / G / B sub-pixels in the X direction or the Y direction. When misalignment occurs in the X direction or the Y direction, a large number of or even all the spacers cannot effectively support the FMM, so that the FMM is prone to scratch the organic light-emitting layer in the pixel opening, thereby causing various defects. It should be noted that the same environment mentioned above refers to the same type, quantity, and arrangement of the sub-pixels around the positions of different spacers.
[0051] To this end, embodiments of the present disclosure provide a display substrate, which comprises a substrate, a plurality of sub-pixels on the substrate, and a plurality of spacers, each of which is located in a spacing region between adjacent sub-pixels. The plurality of sub-pixels comprises a first color sub-pixel, a second color sub-pixel, and a third color sub-pixel; the display substrate comprises a first virtual quadrilateral region, and the plurality of spacers comprises 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 are adjacent, and two first color sub-pixels are located at two corners of the first virtual quadrilateral region where the first vertex and the second vertex are located. Since the adjacent first vertex and the second vertex of the first virtual quadrilateral region are respectively provided with the first spacer and the second spacer, and the two corners where the first vertex and the second vertex are located are provided with the two first color sub-pixels, for the two first color sub-pixels provided at the two corners where the first vertex and the second vertex are located, one of the two first color sub-pixels is provided with the first spacer in a first direction, and the other is provided with the second spacer in a 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 direction or the second direction, and one of the first spacer and the second spacer of the adjacent first vertex and the second vertex of the first virtual quadrilateral region cannot effectively support the FMM, since the displacement of the misalignment in the other direction is small, the other of the first spacer and the second spacer can still effectively support the FMM, thereby avoiding the FMM scratching the film layer structure, such as the organic light-emitting layer, of the plurality of sub-pixels on the display substrate, and further avoiding various defects.
[0052] Embodiments of the present disclosure also provide a display device comprising the display substrate described above. Therefore, the display device can also avoid the FMM scratching the plurality of sub-pixels on the display substrate, and further avoid various defects, thereby having a higher product yield and a higher display quality.
[0053] In the following, the display substrate and the display device provided by embodiments of the present disclosure are described in detail in combination with the drawings.
[0054] FIG. 1 is a plan view of a display substrate according to an embodiment of the present disclosure. As shown in FIG. 1, the display substrate 100 includes a substrate 110, a plurality of sub-pixels 120 on the substrate 110, and a plurality of spacers 130, each of which is located in an interval region between adjacent sub-pixels 120. The plurality of sub-pixels 120 includes first color sub-pixels 120A, second color sub-pixels 120B, and third color sub-pixels 120C. The first color sub-pixels 120A are configured to emit light of a first color, the second color sub-pixels 120B are configured to emit light of a second color, and the third color sub-pixels 120C are configured to emit light of a third color. The plurality of spacers 130 can be used to support an extremely thin metal mask when forming an organic light-emitting layer of each sub-pixel 120. In addition, the organic light-emitting layers of the first color sub-pixels 120A, the second color sub-pixels 120B, and the third color sub-pixels 120C are usually formed using different extremely thin metal masks.
[0055] For example, the first color described above can be red, the wavelength range of which can be 620-750 nm, the second color can be green, the wavelength range of which can be 495-570 nm, and the third color can be blue, the wavelength range of which can be 450-495 nm.
[0056] As shown in FIG. 1, the display substrate 100 includes a first virtual quadrilateral region A, the plurality of spacers 130 includes a first spacer 131 and a second spacer 132, and one first spacer 131 and one second spacer 132 are located at a first vertex P11 and a second vertex P12 of the first virtual quadrilateral region A, respectively. The first vertex P11 and the second vertex P12 are adjacent, or the first vertex P11 and the second vertex P12 are located at two ends of the same edge of the first virtual quadrilateral region A. Two first color sub-pixels 120A are located at two corners of the first virtual quadrilateral region A at which the first vertex P11 and the second vertex P12 are located.
[0057] In the display substrate provided in the embodiments of the present disclosure, the first and second adjacent vertices of the first virtual quadrilateral region are respectively provided with the first and second spacers, and the two corners where the first and second vertices are located are provided with two first color sub-pixels. Therefore, for the two first color sub-pixels provided at the two corners where the first and second vertices are located, one of the two first color sub-pixels is provided with the first spacer in the first direction, and the other is provided with the second spacer in the second direction. That is, one of the two first color sub-pixels is adjacent to the first spacer in the first direction, and the other is adjacent to the second spacer in the second direction. When the FMM used to form the first color sub-pixel and the display substrate are misaligned in the first direction or the second direction, and one of the first and second spacers of the first and second adjacent vertices of the first virtual quadrilateral region cannot effectively support the FMM, since the displacement of the misalignment in the other direction is small, the other one of the first and second spacers can still effectively support the FMM, thereby avoiding the FMM scratching the film layer structure, such as the organic light-emitting layer, of the plurality of sub-pixels on the display substrate, and further avoiding various defects.
[0058] In some examples, as shown in FIG. 1, the plurality of sub-pixels 120 includes a first pixel group 141 and a second pixel group 142; the first pixel group 141 includes first color sub-pixels 120A and third color sub-pixels 120C arranged in the first direction and two second color sub-pixels 120B arranged in the second direction, and the second pixel group 142 includes two second color sub-pixels 120B arranged in the first direction and first color sub-pixels 120A and third color sub-pixels 120C arranged in the second direction. It can be seen that the types and quantities of sub-pixels in the first pixel group 141 and the second pixel group 142 are the same, but the arrangement manners are different.
[0059] In some examples, as shown in FIG. 1, the first spacer 131 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 first pixel group 141, and the second spacer 132 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 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 the 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 direction or the second direction, and one of the first spacer and the second spacer cannot effectively support the FMM, due to the smaller displacement of the misalignment in the other direction, the other one of the first spacer and the second spacer can still effectively support the FMM, thereby avoiding the FMM scratching the film layer structure of the plurality of sub-pixels on the display substrate, and further 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, and for the third color sub-pixel in the second pixel group, the second spacer is located on one side of the third color sub-pixel in the second direction. When the FMM used to form the third color sub-pixel and the display substrate are misaligned in the first direction or the second direction, and one of the first spacer and the second spacer cannot effectively support the FMM, due to the smaller displacement of the misalignment in the other direction, the other one of the first spacer and the second spacer can still effectively support the FMM, thereby avoiding the FMM scratching the film layer structure of the plurality of sub-pixels on the display substrate, and further 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, and for the second color sub-pixel in the second pixel group, the second spacer is located on one side of the second color sub-pixel in the first direction. When the FMM used to form the second color sub-pixel and the display substrate are misaligned in the first direction or the second direction, and one of the first spacer and the second spacer cannot effectively support the FMM, due to the smaller displacement of the misalignment in the other direction, the other one of the first spacer and the second spacer can still effectively support the FMM, thereby avoiding the FMM scratching the film layer structure of the plurality of sub-pixels on the display substrate, and further avoiding various defects.
[0063] In some examples, as shown in FIG. 1, the plurality of spacers 130 includes a third spacer 133 and a fourth spacer 134, which are located at a third vertex P13 and a 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 two end points 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 FIG. 1, two first color sub-pixels 120A are located at two corners where the third vertex P13 and the fourth vertex P14 of the first virtual quadrilateral region A are located. Since the adjacent first vertex and the adjacent second vertex of the first virtual quadrilateral region are respectively provided with the first spacer and the second spacer, the adjacent third vertex and the adjacent fourth vertex are respectively provided with the third spacer and the fourth spacer, and the four corners where the first vertex, the second vertex, the third vertex and the fourth vertex of the first virtual quadrilateral region are located are provided with four first color sub-pixels, for the four first color sub-pixels located at the four corners where the first vertex, the second vertex, the third vertex and the fourth vertex are located, a first one of the four first color sub-pixels is provided with the first spacer on a first side in a first direction, a second one of the four first color sub-pixels is provided with the third spacer on a second side in the first direction, a third one of the four first color sub-pixels is provided with the second spacer on a third side in a second direction, and a fourth one of the four first color sub-pixels is provided with the fourth spacer on a fourth side in the second direction. When the FMM used to form the first color sub-pixel and the display substrate are misaligned in the first direction to the first side, and the first spacer cannot effectively support the FMM, the second spacer, the third spacer and the fourth spacer can also effectively support the FMM, thereby avoiding the FMM scratching the film layer structure of the plurality of sub-pixels on the display substrate, such as the organic light-emitting layer, and further avoiding various defects. Similarly, when misalignment in other directions occurs, the FMM can also avoid scratching the film layer structure of the plurality of sub-pixels on the display substrate, which will not be described herein.
[0065] In some examples, as shown in FIG. 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 FIG. 1, the plurality of sub-pixels 120 includes a third pixel group 143 and a fourth pixel group 144, the arrangement of the sub-pixels 120 in the fourth pixel group 144 is mirror-symmetrical to the arrangement of the sub-pixels 120 in the second pixel group 142 with respect to a first virtual straight line extending along the first direction, and the arrangement of the sub-pixels 120 in the third pixel group 143 is mirror-symmetrical to the arrangement of the sub-pixels 120 in the first pixel group 141 with respect to a second virtual straight line extending along the second direction. That is, the third pixel group 143 includes 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, and 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 FIG. 1, the third spacer 133 is located in the spacing 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 spacing 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.
[0068] In the display substrate provided in this example, since the first spacer, the second spacer, the third spacer and the fourth spacer are respectively located in the first pixel group, the second pixel group, the third pixel group and the fourth pixel group, for the plurality of first color sub-pixels on the display substrate, there are four orientation settings of the spacers, that is, some first color sub-pixels are provided with spacers on the first side in the first direction, some first color sub-pixels are provided with spacers on the second side in the second direction, some first color sub-pixels are provided with spacers on the third side in the second direction, and some first color sub-pixels are provided with spacers on the fourth side in the second direction. Therefore, when the FMM for forming the first color sub-pixel and the display substrate are misaligned in one orientation and cause some spacers to fail to effectively support the FMM, the spacers in other orientations can still effectively support the FMM, thereby avoiding the FMM scratching the film layer structure of the plurality of sub-pixels on the display substrate, and further avoiding various defects.
[0069] In some examples, as shown in FIG. 1, the length of the virtual edge on which the first vertex P11 and the second vertex P12 of the first virtual quadrilateral region A are located is greater than the size of the N first color sub-pixels 120A in the extension direction of the virtual edge, and the value of N is greater than or equal to 2. That is, the range or size of the first virtual quadrilateral region can be set according to actual needs.
[0070] In some examples, as shown in FIG. 1, the first virtual quadrilateral region A is rectangular in shape. Thus, a line between the first spacer 131 located near the first vertex P11 of the first virtual quadrilateral region A and the first color sub-pixel 120A is perpendicular to a line between the second spacer 132 located near the second vertex P12 of the first virtual quadrilateral region A and the first color sub-pixel 120A. Of course, embodiments of the present disclosure include but are not limited to this, and the first virtual quadrilateral region can also be other shapes.
[0071] In some examples, as shown in FIG. 1, the display substrate 100 includes a second virtual quadrilateral region B, one first spacer 131 and one second spacer 132 are located at a fifth vertex P21 and a sixth vertex P22 of the second virtual quadrilateral region B, respectively, the fifth vertex P21 and the sixth vertex P22 are adjacent, or are located at two end points of the same edge of the second virtual quadrilateral region B. Two second color sub-pixels 120B are located at two corners of the second virtual quadrilateral region B where the fifth vertex P21 and the sixth vertex P22 are located.
[0072] In the display substrate provided by the embodiments of the present disclosure, since the adjacent fifth vertex and sixth vertex of the second virtual quadrilateral region are respectively provided with the first spacer and the second spacer, and the two corners where the fifth vertex and the sixth vertex are located are provided with the two second color sub-pixels, for the two second color sub-pixels provided at the two corners where the fifth vertex and the sixth vertex are located, one of the two second color sub-pixels is provided with the first spacer in the first direction, and the other is provided with the second spacer in the second direction. That is, 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 direction or the second direction, and one of the first spacer and the second spacer of the adjacent fifth vertex and sixth vertex of the second virtual quadrilateral region cannot effectively support the FMM, since the displacement of the misalignment in the other direction is small, the other of the first spacer and the second spacer can still effectively support the FMM, thereby avoiding the FMM scratching the film layer structure, such as the organic light-emitting layer, of the plurality of sub-pixels on the display substrate, and further avoiding various defects.
[0073] In some examples, as shown in FIG. 1, the second virtual quadrilateral region B has a rectangular shape. Thus, the line between the first spacer 131 located near the fifth vertex P21 of the second virtual quadrilateral region B and the second color sub-pixel 120B is perpendicular to the line between the second spacer 132 located near the sixth vertex P22 of the second virtual quadrilateral region B and the second color sub-pixel 120B. Of course, embodiments of the present disclosure include but are not limited to this, and the second virtual quadrilateral region can also have other shapes.
[0074] In some examples, as shown in FIG. 1, the length of the virtual edge on which the fifth vertex P21 and the sixth vertex P22 of the second virtual quadrilateral region B are located is greater than the size of N second color sub-pixels 120A in the extension direction of the virtual edge, and 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 FIG. 1, the display substrate 100 includes a third virtual quadrilateral region C, one first spacer 131 and one 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 end points 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 on which the seventh vertex P31 and the eighth vertex P32 are located. It should be noted that the rectangular blocks shown as A, B, C, and D in FIG. 1 are not actual structures, but are schematically shown to show the range of the above-mentioned various virtual quadrilateral regions; and the edges of the above-mentioned various virtual quadrilateral regions are defined by the centers of the above-mentioned vertices or spacers, and are not defined by the rectangular blocks shown as A, B, C, and D.
[0076] In the display substrate provided by the embodiments of the present disclosure, the first and second spacers are arranged at the adjacent seventh and eighth vertices of the third virtual quadrilateral region, and the two second color sub-pixels are arranged at the two corners where the seventh and eighth vertices are located. Therefore, for the two third color sub-pixels arranged at the two corners where the seventh and eighth vertices are located, one of the two third color sub-pixels is arranged with the first spacer in the first direction, and the other is arranged with the 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 direction or the second direction, and one of the first and second spacers of the adjacent seventh and eighth vertices of the third virtual quadrilateral region cannot effectively support the FMM, since the displacement of the misalignment in the other direction is small, the other of the first and second spacers can still effectively support the FMM, thereby avoiding the FMM scratching the film layer structure, such as the organic light-emitting layer, of the plurality of sub-pixels on the display substrate, and further avoiding various defects.
[0077] In some examples, as shown in FIG. 1, the third virtual quadrilateral region C is in the shape of a rectangle. Thus, the line between 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 between 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, the embodiments of the present disclosure include but are not limited to this, and the shape of the third virtual quadrilateral region can also be other shapes.
[0078] In some examples, as shown in FIG. 1, the length of the virtual edge where the seventh vertex P31 and the eighth vertex P32 of the third virtual quadrilateral region C are located is greater than the size of the N third color sub-pixels 120C in the extension direction of the virtual edge, and 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 FIG. 1, the display substrate 100 can further include a fourth virtual quadrilateral region D, a first spacer 131 and a second spacer 132 located at a ninth vertex P41 and a tenth vertex P42 of the fourth virtual quadrilateral region D respectively, the ninth vertex P41 and the tenth vertex P42 being adjacent or being two end points of a same virtual side of the fourth virtual quadrilateral region D. Two second color sub-pixels 120B are located at 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 as A, B, C and D in FIG. 1 are not actual structures, but are used to schematically show the ranges of the above-mentioned various virtual quadrilateral regions; and the edges of the above-mentioned various virtual quadrilateral regions are defined by the above-mentioned vertices or the centers of the spacers, rather than the rectangular blocks shown as A, B, C and D.
[0080] In the display substrate provided by the embodiments of the present disclosure, since the first spacer and the second spacer are respectively arranged at the adjacent ninth vertex and the tenth vertex of the fourth virtual quadrilateral region, and the two second color sub-pixels are arranged at the two corners where the ninth vertex and the tenth vertex are located, for the two second color sub-pixels arranged at the two corners where the ninth vertex and the tenth vertex are located, one of the two second color sub-pixels is arranged with the first spacer in the first direction, and the other is arranged with the 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 direction or the second direction, and one of the first spacer and the second spacer of the adjacent ninth vertex and the tenth vertex of the fourth virtual quadrilateral region cannot effectively support the FMM, since the displacement of the misalignment in the other direction is small, the other of the first spacer and the second spacer can still effectively support the FMM, thereby avoiding the FMM scratching the film layer structure, such as the organic light-emitting layer, of the plurality of sub-pixels on the display substrate, and further avoiding various defects.
[0081] In some examples, as shown in FIG. 1, the fourth virtual quadrilateral region D is in the shape of a rectangle. Thus, 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, the embodiments of the present 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 FIG. 1, the length of the virtual edge on which the ninth vertex P41 and the tenth vertex P42 of the fourth virtual quadrilateral region D are located is greater than the size of the N second color sub-pixels 120B in the extension direction of the virtual edge, and 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 FIG. 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 FIG. 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 FIG. 1, each spacer 130 is located adjacent to four sub-pixels 120, and there is no other sub-pixel between the spacer 130 and the adjacent sub-pixels 120. Thus, the spacer can be located in the region surrounded by the four sub-pixels, thereby fully utilizing the space on the display substrate.
[0086] In some examples, as shown in FIG. 1, each spacer 130 is located between the corners of the four adjacent sub-pixels 120, rather than between the edges of the adjacent sub-pixels.
[0087] In some examples, as shown in FIG. 1, the display substrate 100 further includes a pixel isolation structure 150, which includes a first pixel isolation structure 151 and a second pixel isolation structure 152; the first pixel isolation structure 151 is located between adjacent first color sub-pixels 120A and second color sub-pixels 120B; the second pixel isolation 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 region between two first pixel isolation structures 151 and two second pixel isolation structures 152.
[0088] In the display substrate provided in the example, the display substrate 100 can adopt a tandem light-emitting technology, that is, the light-emitting layer 122 of each sub-pixel 120 can include a plurality of light-emitting sub-layers and a charge generation layer between the light-emitting sub-layers. Thus, the display substrate 100 can have a higher light-emitting brightness and service life. When the display substrate 100 adopts the tandem light-emitting technology, the thickness of the light-emitting layer is large, and the height is high. On the other hand, the pixel partition structure 150 can partition the charge generation layers of adjacent sub-pixels 120 to prevent crosstalk. Each spacer 130 is located in the area between two first pixel partition structures 151 and two second pixel partition structures 152, the size of the spacer is further limited, and the thickness of the light-emitting layer is also large, so when the FMM is insufficiently supported, it is more likely to scratch the light-emitting layer 122 and cause various defects. In this case, by adopting the design scheme of the spacer provided in the embodiment of the present disclosure, the display substrate can still avoid the FMM scratching the film layer structure of the plurality of sub-pixels on the display substrate, such as the organic light-emitting layer, and further avoid various defects, so as to have a higher display performance while having a higher yield.
[0089] In some examples, as shown in FIG. 1, 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 first color sub-pixels 120A, second color sub-pixels 120B, and third color sub-pixels 120C; each spacer 130 is located in an interval region between adjacent sub-pixels 120. The plurality of sub-pixels 120 include a plurality of first sub-pixel rows 161 and a plurality of first sub-pixel columns 171, each first sub-pixel row 161 includes a plurality of first color sub-pixels 120A and a plurality of third color sub-pixels 120C arranged alternately in a first direction, each first sub-pixel column 171 includes a plurality of first color sub-pixels 120A and a plurality of third color sub-pixels 120C arranged alternately in a second direction, the plurality of first sub-pixel rows 161 are arranged in the second direction, the plurality of first sub-pixel columns 171 are arranged in the first direction, and the first direction and the second direction intersect. The plurality of spacers 130 described above include first spacers 131 and second spacers 132.
[0090] As shown in FIG. 1, the plurality of first sub-pixel rows 161 include a plurality of first pixel spacer rows 1615, each first pixel spacer row 1615 includes a first spacer 131 located between a first color sub-pixel 120A and a third color sub-pixel 120C adjacent in the first direction; and the plurality of first sub-pixel columns 171 include a plurality of first pixel spacer columns 1715, each first pixel spacer column 1715 includes a second spacer 132 located between a first color sub-pixel 120A and a third color sub-pixel 120C adjacent in the second direction.
[0091] In the display substrate provided by the embodiments of the present disclosure, since each first pixel spacer row 1615 includes the first spacer 131 located between the first color sub-pixel 120A and the third color sub-pixel 120C adjacent in the first direction, and each first pixel spacer column 1715 includes the second spacer 132 located between the first color sub-pixel 120A and the third color sub-pixel 120C adjacent in the second direction, for the first color sub-pixels, part of the first color sub-pixels are provided with the first spacer in the first direction, and part of the first color sub-pixels are provided with the second spacer in the second direction. When the FMM used to form the first color sub-pixels and the display substrate are misaligned in the first direction or the second direction, and one of the first spacer and the second spacer cannot effectively support the FMM, since the displacement of the misalignment in the other direction is small, the other one of the first spacer and the second spacer can still effectively support the FMM, thereby avoiding the FMM scratching the film layer structure of the plurality of sub-pixels on the display substrate, such as the organic light-emitting layer, and further avoiding various defects.
[0092] Similarly, for the third color sub-pixels, part of the third color sub-pixels are provided with the first spacer in the first direction, and part of the third color sub-pixels are provided with the second spacer in the second direction. When the FMM used to form the third color sub-pixels and the display substrate are misaligned in the first direction or the second direction, and one of the first spacer and the second spacer cannot effectively support the FMM, since the displacement of the misalignment in the other direction is small, the other one of the first spacer and the second spacer can still effectively support the FMM, thereby avoiding the FMM scratching the film layer structure of the plurality of sub-pixels on the display substrate, such as the organic light-emitting layer, and further avoiding various defects.
[0093] For example, the first direction and the second direction are perpendicular. Of course, the embodiments of the present disclosure include but are not limited to this, and the first direction and the second direction can also be non-perpendicular.
[0094] In some examples, as shown in FIG. 1, in the plurality of first sub-pixel rows 161, the plurality of first pixel spacer rows 1615 are uniformly distributed. For example, one first pixel spacer row 1615 is arranged every four first sub-pixel rows 161. Of course, the embodiments of the present disclosure include but are not limited to this.
[0095] In some examples, as shown in FIG. 1, in the plurality of first sub-pixel columns 171, the plurality of first pixel spacer columns 1715 are uniformly distributed. For example, one first pixel spacer column 1715 is arranged every four first sub-pixel columns 171. Of course, the embodiments of the present disclosure include but are not limited to this.
[0096] In some examples, as shown in FIG. 1, the first spacers 131 in two first pixel spacer rows 1615 adjacent in the second direction are aligned in the second direction, i.e., the respective first spacers 131 in the two first pixel spacer rows 1615 adjacent in the second direction are located on a straight line extending along the second direction.
[0097] In some examples, as shown in FIG. 1, the second spacers 132 in the first pixel spacer columns 1715 adjacent in the first direction are aligned in the first direction, i.e., the respective second spacers 132 in the first pixel spacer columns 1715 adjacent in the first direction are located on a straight line extending along the first direction.
[0098] In some examples, as shown in FIG. 1, the plurality of sub-pixels 120 includes a plurality of second sub-pixel rows 162 and a plurality of second sub-pixel columns 172, each second sub-pixel row 162 includes a plurality of second color sub-pixels 120B arranged alternately along the first direction, each second sub-pixel column 172 includes a plurality of second color sub-pixels 120B arranged alternately along the second direction, the plurality of second sub-pixel rows 162 are arranged along the second direction, and the plurality of second sub-pixel columns 172 are arranged along the first direction.
[0099] In some examples, as shown in FIG. 1, the plurality of second sub-pixel rows 162 includes a plurality of second pixel spacer rows 1625, each second pixel spacer row 1625 includes a second spacer 132 located between second color sub-pixels 120B adjacent in the first direction, and the plurality of second sub-pixel columns 172 includes a plurality of second pixel spacer columns 1725, each second pixel spacer column 1725 includes a first spacer 131 located between second color sub-pixels 120B adjacent in the second direction.
[0100] In the display substrate provided in the embodiments of the present disclosure, since each second pixel spacer row 1625 includes a second spacer 132 located between second color sub-pixels 120B adjacent in the first direction, and each second pixel spacer column 1725 includes a first spacer 131 located between second color sub-pixels 120B adjacent in the second direction, for the second color sub-pixels, part of the second color sub-pixels are provided with a second spacer in the first direction, and part of the second color sub-pixels are provided with a first 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 direction or the second direction, and one of the first spacers and the second spacers cannot effectively support the FMM, since the displacement of the other direction is small, the other one of the first spacers and the second spacers can still effectively support the FMM, thereby avoiding the FMM scratching the film layer structure of the plurality of sub-pixels on the display substrate, such as the organic light-emitting layer, and further avoiding various defects.
[0101] In some examples, as shown in FIG. 1, the plurality of first sub-pixel rows 161 and the plurality of second sub-pixel rows 162 are arranged alternately in the second direction, and the plurality of first sub-pixel columns 171 and the plurality of second sub-pixel columns 172 are arranged alternately in the first direction.
[0102] In some examples, as shown in FIG. 1, in the plurality of second sub-pixel rows 162, the plurality of second pixel spacer rows 1625 are uniformly distributed. For example, one second pixel spacer row 1625 is arranged every four second sub-pixel rows 162. Of course, embodiments of the present disclosure include but are not limited to this.
[0103] In some examples, as shown in FIG. 1, in the plurality of second sub-pixel columns 172, the plurality of second pixel spacer columns 1725 are uniformly distributed. For example, one second pixel spacer column 1725 is arranged every four second sub-pixel columns 172. Of course, embodiments of the present disclosure include but are not limited to this.
[0104] In some examples, as shown in FIG. 1, the second spacers 132 in two adjacent second pixel spacer rows 1625 in the second direction are aligned in the second direction, i.e., the corresponding second spacers 132 in two adjacent second pixel spacer rows 1625 in the second direction are located on a straight line extending in the second direction.
[0105] In some examples, as shown in FIG. 1, the first spacers 131 in the adjacent second pixel spacer columns 1725 in the first direction are aligned in the first direction, i.e., the corresponding first spacers 131 in the adjacent second pixel spacer columns 1725 in the first direction are located on a straight line extending in the first direction. FIG. 2 is a plan view of another display substrate provided by an embodiment of the present disclosure. As shown in FIG. 2, the display substrate 100 includes a substrate 110, a plurality of sub-pixels 120 on the substrate 110, and a plurality of spacers 130, each of which is located in a spacing region between adjacent sub-pixels 120. The plurality of sub-pixels 120 includes first color sub-pixels 120A, second color sub-pixels 120B, and third color sub-pixels 120C. The first color sub-pixels 120A are configured to emit light of a first color, the second color sub-pixels 120B are configured to emit light of a second color, and the third color sub-pixels 120C are configured to emit light of a third color. When forming the organic light-emitting layer of each sub-pixel 120, the plurality of spacers 130 can be used to support an extremely fine metal mask; in addition, the organic light-emitting layers of the first color sub-pixels 120A, the second color sub-pixels 120B, and the third color sub-pixels 120C are usually formed using different extremely fine metal masks.
[0106] For example, the first color can be red, the wavelength range of which can be 620-750 nm, the second color can be green, the wavelength range of which can be 495-570 nm, and the third color can be blue, the wavelength range of which can be 450-495 nm.
[0107] As shown in FIG. 2, the display substrate 100 includes a first virtual quadrilateral region A, and the plurality of spacers 130 includes a first spacer 131 and a second spacer 132, one first spacer 131 and one second spacer 132 are respectively located at a first vertex P11 and a second vertex P12 of the first virtual quadrilateral region A; the first vertex P11 and the second vertex P12 are adjacent, or the first vertex P11 and the second vertex P12 are located at two ends of the same edge of the first virtual quadrilateral region A. Two first color sub-pixels 120A are located at two corners of the first virtual quadrilateral region A where the first vertex P11 and the second vertex P12 are located.
[0108] In the display substrate provided in the embodiments of the present disclosure, since the first vertex and the second vertex of the first virtual quadrilateral region are respectively provided with the first spacer and the second spacer, and the two corners where the first vertex and the second vertex are located are provided with the two first color sub-pixels, for the two first color sub-pixels provided at the two corners where the first vertex and the second vertex are located, one of the two first color sub-pixels is provided with the first spacer in the first direction, and the other is provided with the second spacer in the second direction. That is, one of the two first color sub-pixels is adjacent to the first spacer in the first direction, and the other is adjacent to the second spacer in the second direction. When the FMM used to form the first color sub-pixel and the display substrate are misaligned in the first direction or the second direction, and one of the first spacer and the second spacer of the first vertex and the second vertex of the first virtual quadrilateral region cannot effectively support the FMM, since the displacement of the misalignment in the other direction is small, the other of the first spacer and the second spacer can still effectively support the FMM, thereby avoiding the FMM scratching the film layer structure, such as the organic light-emitting layer, of the plurality of sub-pixels on the display substrate, and further avoiding various defects.
[0109] In some examples, as shown in FIG. 2, the plurality of sub-pixels 120 includes a first pixel group 141 and a second pixel group 142; the first pixel group 141 includes the first color sub-pixel 120A and the third color sub-pixel 120C arranged in the first direction and the two second color sub-pixels 120B arranged in the second direction, and the second pixel group 142 includes the two second color sub-pixels 120B arranged in the first direction and the first color sub-pixel 120A and the third color sub-pixel 120C arranged in the second direction. It can be seen that the types and quantities of the sub-pixels in the first pixel group 141 and the second pixel group 142 are the same, but the arrangement manners are different.
[0110] In some examples, as shown in FIG. 2, the first spacers 131 are located in the spacing regions surrounded by the first color sub-pixels 120A, the second color sub-pixels 120B and the third color sub-pixels 120C in the first pixel group 141, and the second spacers 132 are located in the spacing regions surrounded by the first color sub-pixels 120A, the second color sub-pixels 120B and the third color sub-pixels 120C in the second pixel group 142. That is, the first spacers 131 and the second spacers 132 are in different environments.
[0111] In the display substrate provided in this example, for the first color sub-pixels in the first pixel group, the first spacers are located on one side of the first color sub-pixels in the first direction, and for the first color sub-pixels in the second pixel group, the second spacers are located on one side of the first color sub-pixels in the second direction. When the FMM used to form the first color sub-pixels and the display substrate are misaligned in the first direction or the second direction, and one of the first spacers and the second spacers cannot effectively support the FMM, due to the smaller displacement of the misalignment in the other direction, the other of the first spacers and the second spacers can still effectively support the FMM, thereby avoiding the FMM scratching the film layer structure of the plurality of sub-pixels on the display substrate, and further avoiding various malfunctions.
[0112] Similarly, for the third color sub-pixels in the first pixel group, the first spacers are located on one side of the third color sub-pixels in the first direction, and for the third color sub-pixels in the second pixel group, the second spacers are located on one side of the third color sub-pixels in the second direction. When the FMM used to form the third color sub-pixels and the display substrate are misaligned in the first direction or the second direction, and one of the first spacers and the second spacers cannot effectively support the FMM, due to the smaller displacement of the misalignment in the other direction, the other of the first spacers and the second spacers can still effectively support the FMM, thereby avoiding the FMM scratching the film layer structure of the plurality of sub-pixels on the display substrate, and further avoiding various malfunctions.
[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, and for the second color sub-pixel in the second pixel group, the second spacer is located on one side of the second color sub-pixel in the first direction. When the FMM used to form the second color sub-pixel and the display substrate are misaligned in the first direction or the second direction, and one of the first spacer and the second spacer cannot effectively support the FMM, due to the smaller displacement of the other direction caused by the misalignment, the other one of the first spacer and the second spacer can still effectively support the FMM, thereby avoiding the FMM from scratching the film layer structure of the plurality of sub-pixels on the display substrate, and further avoiding various defects.
[0114] In some examples, as shown in FIG. 2, the first spacer 131 and the second spacer 132 are different in size. For example, the size of the first spacer 131 is greater than the size of the second spacer 132. As described above, due to the different environments in which the first spacer 131 and the second spacer 132 are located, the space at the location of the first spacer 131 is larger, and therefore the size of the first spacer 131 can be set to be greater than the size of the second spacer 132, so that the first spacer 131 can make full use of the spacing area in the first pixel group 141, and the first spacer 131 can support the FMM in a larger range, thereby further reducing the risk of the FMM scratching the film layer structure of the plurality of sub-pixels on the display substrate.
[0115] In some examples, as shown in FIG. 2, the first spacer 131 and the second spacer 132 are different in shape. As described above, due to the different environments in which the first spacer 131 and the second spacer 132 are located, the first spacer 131 and the second spacer 132 can be set to specific shapes according to the environment in which they are located, so as to make full use of the spacing area in the first pixel group 141 and the second pixel group 142.
[0116] For example, as shown in FIG. 2, the first spacer 131 is rectangular in shape, and the second spacer 132 is circular in shape. Of course, the embodiments of the present disclosure include but are not limited to this, and the shapes of the first spacer and the second spacer can be set according to actual conditions. It should be noted that the shape of the spacer described above refers to the planar shape of the spacer, that is, the shape of the orthogonal projection of the spacer on the substrate.
[0117] In some examples, as shown in FIG. 2, the plurality of spacers 130 includes a third spacer 133 and a fourth spacer 134, which are respectively located at a third vertex P13 and a fourth vertex P14 of the first virtual quadrilateral region A, the third vertex P13 and the fourth vertex P14 are adjacent, or the third vertex P13 and the fourth vertex P14 are located at two end points 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 FIG. 2, two first color sub-pixels 120A are located at two corners where the third vertex P13 and the fourth vertex P14 of the first virtual quadrilateral region A are located. Since the adjacent first vertex and the adjacent second vertex of the first virtual quadrilateral region are respectively provided with the first spacer and the second spacer, the adjacent third vertex and the adjacent fourth vertex are respectively provided with the third spacer and the fourth spacer, and the four corners where the first vertex, the second vertex, the third vertex and the fourth vertex of the first virtual quadrilateral region are located are provided with four first color sub-pixels, for the four first color sub-pixels located at the four corners where the first vertex, the second vertex, the third vertex and the fourth vertex are located, a first one of the four first color sub-pixels is provided with the first spacer on a first side in the first direction, a second one of the four first color sub-pixels is provided with the third spacer on a second side in the first direction, a third one of the four first color sub-pixels is provided with the second spacer on a third side in the second direction, and a fourth one of the four first color sub-pixels is provided with the fourth spacer on a fourth side in the second direction. When the FMM used to form the first color sub-pixel and the display substrate are misaligned in the first direction to the first side, and the first spacer cannot effectively support the FMM, the second spacer, the third spacer and the fourth spacer can also effectively support the FMM, thereby avoiding the FMM scratching the film layer structure, such as the organic light-emitting layer, of the plurality of sub-pixels on the display substrate, and further avoiding various defects. Similarly, when misalignment in other directions occurs, the FMM can also avoid scratching the film layer structure of the plurality of sub-pixels on the display substrate, which will not be described herein.
[0119] In some examples, as shown in FIG. 2, the plurality of sub-pixels 120 includes a third pixel group 143 and a fourth pixel group 144, the arrangement of the sub-pixels 120 in the fourth pixel group 144 is mirror-symmetrical to the arrangement of the sub-pixels 120 in the second pixel group 142 with respect to a first virtual straight line extending along the first direction, and the arrangement of the sub-pixels 120 in the third pixel group 143 is mirror-symmetrical to the arrangement of the sub-pixels 120 in the first pixel group 141 with respect to a second virtual straight line extending along the second direction. That is, the third pixel group 143 includes the third color sub-pixels 120C and the first color sub-pixels 120A arranged along the first direction and the two second color sub-pixels 120B arranged along the second direction, and the fourth pixel group 144 includes the two second color sub-pixels 120B arranged along the first direction and the third color sub-pixels 120C and the first color sub-pixels 120A arranged along the second direction.
[0120] In some examples, as shown in FIG. 2, the third spacers 133 are located in the spacing regions surrounded by the first color sub-pixels 120A, the second color sub-pixels 120B and the third color sub-pixels 120C in the third pixel group 143, and the fourth spacers 134 are located in the spacing regions surrounded by the first color sub-pixels 120A, the second color sub-pixels 120B and the third color sub-pixels 120C in the fourth pixel group 144.
[0121] In the display substrate provided in this example, since the first spacers, the second spacers, the third spacers and the fourth spacers are respectively located in the first pixel group, the second pixel group, the third pixel group and the fourth pixel group, for the plurality of first color sub-pixels on the display substrate, there are four orientation settings of spacers, that is, some first color sub-pixels are provided with spacers on the first side in the first direction, some first color sub-pixels are provided with spacers on the second side in the second direction, some first color sub-pixels are provided with spacers on the third side in the second direction, and some first color sub-pixels are provided with spacers on the fourth side in the second direction. Therefore, when the FMM for forming the first color sub-pixels and the display substrate are misaligned in one orientation and cause some spacers to be unable to effectively support the FMM, the spacers in other orientations can still effectively support the FMM, thereby avoiding the FMM scratching the film layer structure of the plurality of sub-pixels on the display substrate, and further avoiding various defects.
[0122] In some examples, as shown in FIG. 2, the third spacers 133 and the fourth spacers 134 are different in size. For example, the third spacers 133 are larger in size than the fourth spacers 134. As described above, since the third spacers 133 and the fourth spacers 134 are in different environments, the third spacers 133 are in a larger space, and thus the third spacers 133 can be set to be larger in size than the fourth spacers 134, so that the third spacers 133 can fully utilize the space in the third pixel group 143, and the third spacers 133 can support the FMM in a larger range, thereby further reducing the risk of the FMM scratching the film layer structure of the plurality of sub-pixels on the display substrate.
[0123] In some examples, as shown in FIG. 2, the first spacers 131 and the third spacers 133 are substantially equal in size, and the second spacers 132 and the fourth spacers 134 are substantially equal in size.
[0124] In some examples, as shown in FIG. 2, the third spacers 133 and the fourth spacers 134 are different in shape. As described above, since the third spacers 133 and the fourth spacers 134 are in different environments, the third spacers 133 and the fourth spacers 134 can be set to specific shapes according to the environments, so as to fully utilize the space in the third pixel group 143 and the fourth pixel group 144.
[0125] For example, as shown in FIG. 2, the third spacers 133 are rectangular in shape, and the fourth spacers 134 are circular in shape. Of course, the embodiments of the present disclosure include but are not limited to this, and the shapes of the third spacers and the fourth spacers can be set according to actual conditions.
[0126] In some examples, on the basis of the embodiment shown in FIG. 2, the display substrate can only include the first spacers and the third spacers which are larger in size, and the second spacers and the fourth spacers are not provided, thereby reducing the density of the spacers.
[0127] In some examples, as shown in FIG. 2, the display substrate 100 can also include a second virtual quadrilateral area B, a third virtual quadrilateral area C, and a fourth virtual quadrilateral area D. The second virtual quadrilateral area B, the third virtual quadrilateral area C, and the fourth virtual quadrilateral area D are described in the related description of FIG. 1, and will not be described here.
[0128] In some examples, as shown in FIG. 2, each spacer 130 is disposed adjacent to four sub-pixels 120, and there is no other sub-pixel between the spacer 130 and the adjacent sub-pixels 120. In this way, the spacer can be disposed in the area surrounded by the four sub-pixels, thereby fully utilizing the space on the display substrate.
[0129] In some examples, as shown in FIG. 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 FIG. 2, 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 region between two first pixel partition structures 151 and two second pixel partition structures 152.
[0131] In the display substrate provided in this example, the display substrate 100 can employ a tandem light-emitting technology, i.e., the light-emitting layer 122 of each sub-pixel 120 can include multiple light-emitting sub-layers and charge generation layers between the light-emitting sub-layers. Thus, the display substrate 100 can have higher light-emitting brightness and service life. When the display substrate 100 employs the tandem light-emitting technology, the thickness of the light-emitting layer is larger, and the height is higher. On the other hand, the pixel partition structure 150 can partition the charge generation layers of adjacent sub-pixels 120 to prevent crosstalk. Each spacer 130 is located in the region between two first pixel partition structures 151 and two second pixel partition structures 152, the size of the spacer is further limited, and the thickness of the light-emitting layer is also larger, so when the FMM is not supported enough, it is more likely to scratch the light-emitting layer 122, causing various defects. In this case, by employing the design scheme of the spacer provided in the embodiments of the present disclosure, the display substrate can still avoid the FMM scratching the film layer structure, such as the organic light-emitting layer, of multiple sub-pixels on the display substrate when employing the tandem light-emitting technology, thereby avoiding various defects, so as to have higher display performance while having higher yield.
[0132] FIG. 3A is a partial enlarged schematic view of a display substrate provided in an embodiment of the present disclosure; and FIG. 3B is a partial enlarged schematic view of another display substrate provided in an embodiment of the present disclosure.
[0133] As shown in FIG. 3A, the display substrate 100 includes a substrate 110, a plurality of sub-pixels 120 on the substrate 110, and a plurality of spacers 130, each of which is 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 can include an anode 121, a light-emitting layer 122, and a pixel opening 123 located within a pixel defining layer, the light-emitting layer 122 being 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 a fine metal mask (FMM).
[0134] As shown in FIG. 3A, when the FMM and the display substrate 100 are misaligned in the second direction Y, the spacers 130 can come into contact with the opening edges of the FMM, causing scratches, thereby generating particulate matter, and light-emitting display of the sub-pixels. On the other hand, when the FMM and the display substrate 100 are misaligned in the second direction Y by a large distance, the spacers 130 can fall into the opening edges of the FMM, failing to support the FMM, thereby causing the FMM to scratch the light-emitting layer 122, resulting in various defects.
[0135] As shown in FIG. 3A, the display substrate 100 can employ a tandem light-emitting technology, i.e., the light-emitting layer 122 of each sub-pixel 120 can include a plurality of light-emitting sub-layers and a charge generation layer between the light-emitting sub-layers. Thus, the display substrate 100 can have higher light-emitting brightness and service life. When the display substrate 100 employs the tandem light-emitting technology, the thickness of the light-emitting layer is larger, and the height is higher. On the other hand, in order to block the charge generation layers of adjacent sub-pixels 120 and prevent crosstalk, the display substrate 100 is also provided with a pixel blocking structure 150. In this way, the size of the spacers is further limited, and the thickness of the light-emitting layer is also larger, so that when the FMM is insufficiently supported, it is more likely to scratch the light-emitting layer 122, resulting in various defects. In this case, by employing the design scheme of the spacers provided in the embodiments of the present disclosure, the display substrate can still avoid the FMM scratching the film layer structure of the plurality of sub-pixels on the display substrate, such as the organic light-emitting layer, while employing the tandem light-emitting technology, thereby avoiding the generation of various defects, so as to have higher display performance while having higher yield.
[0136] As shown in FIG. 3B, the size of the spacers 130 adopted by the display substrate 100 is larger than that of the spacers 130 in FIG. 3A, so that the spacers can support the FMM in a larger range, thereby further reducing the risk of the FMM scratching the film layer structure of the plurality of sub-pixels on the display substrate.
[0137] FIG. 4 is a schematic diagram of another display substrate provided by an embodiment of the present disclosure. As shown in FIG. 4, the display substrate 100 includes a substrate 110, a plurality of sub-pixels 120 on the substrate 110, and a plurality of spacers 130, each of which is located in a spacing region between adjacent sub-pixels 120. The plurality of sub-pixels 120 includes first color sub-pixels 120A, second color sub-pixels 120B, and third color sub-pixels 120C. The first color sub-pixels 120A are configured to emit light of a first color, the second color sub-pixels 120B are configured to emit light of a second color, and the third color sub-pixels 120C are configured to emit light of a third color. When forming the organic light-emitting layer of each sub-pixel 120, the plurality of spacers 130 can be used to support an extremely fine metal mask; in addition, the organic light-emitting layers of the first color sub-pixels 120A, the second color sub-pixels 120B, and the third color sub-pixels 120C are usually formed using different extremely fine metal masks.
[0138] For example, the first color described above can be red, the wavelength range of which can be 620-750 nanometers, the second color can be green, the wavelength range of which can be 495-570 nanometers, and the third color can be blue, the wavelength range of which can be 450-495 nanometers.
[0139] As shown in FIG. 4, the display substrate 100 includes a first virtual quadrilateral region A, the plurality of spacers 130 includes a first spacer 131 and a second spacer 132, and one first spacer 131 and one second spacer 132 are located at a first vertex P11 and a second vertex P12 of the first virtual quadrilateral region A, respectively. The first vertex P11 and the second vertex P12 are adjacent, or the first vertex P11 and the second vertex P12 are located at two ends of the same edge of the first virtual quadrilateral region A. Two first color sub-pixels 120A are located at two corners of the first virtual quadrilateral region A at which the first vertex P11 and the second vertex P12 are located.
[0140] As shown in FIG. 4, the plurality of spacers 130 further includes a third spacer 133 and a fourth spacer 134, one first spacer 133 and one second spacer 134 are respectively located at a third vertex P13 and a fourth vertex P14 of the first virtual quadrilateral region A; the third vertex P13 and the fourth vertex P14 are adjacent, or the third vertex P13 and the fourth vertex P14 are located at two ends of the same edge of the first virtual quadrilateral region A. Two second color sub-pixels 120B are respectively located at two corner portions where the third vertex P13 and the fourth vertex P14 of the first virtual quadrilateral region A are located.
[0141] In the display substrate provided by the embodiments of the present disclosure, since the first vertex and the second vertex of the first virtual quadrilateral region are respectively provided with the first spacer and the second spacer, and the two corner portions where the first vertex and the second vertex are located are provided with the two first color sub-pixels, for the two first color sub-pixels provided at the two corner portions where the first vertex and the second vertex are located, one of the two first color sub-pixels is provided with the first spacer in the first direction, and the other is provided with the second spacer in the second direction. That is, one of the two first color sub-pixels is adjacent to the first spacer in the first direction, and the other is adjacent to the second spacer in the second direction. When the FMM used to form the first color sub-pixel and the display substrate are misaligned in the first direction or the second direction, and one of the first spacer and the second spacer of the adjacent first vertex and the second vertex of the first virtual quadrilateral region cannot effectively support the FMM, since the displacement of the misalignment in the other direction is small, the other one of the first spacer and the second spacer can still effectively support the FMM, thereby avoiding the FMM scratching the film layer structure, such as the organic light-emitting layer, of the plurality of sub-pixels on the display substrate, and further avoiding various defects.
[0142] Similarly, since the third and fourth adjacent vertices of the first virtual quadrilateral region are respectively provided with the third and fourth spacers, and the two corners where the third and fourth vertices are located are provided with two second color sub-pixels, for the two second color sub-pixels provided at the two corners where the third and fourth vertices are located, one of the two second color sub-pixels is provided with the third spacer in the first direction, and the other is provided with the fourth spacer in the second direction. That is, one of the two second color sub-pixels is adjacent to the third spacer in the first direction, and the other is adjacent to the fourth spacer in the second direction. When the FMM used to form the second color sub-pixel and the display substrate are misaligned in the first direction or the second direction, and one of the third and fourth spacers of the third and fourth adjacent 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 third and fourth spacers can still effectively support the FMM, thereby avoiding the FMM scratching the film layer structure, such as the organic light-emitting layer, of the plurality of sub-pixels on the display substrate, and further avoiding various defects.
[0143] In summary, in the display substrate shown in FIG. 4, the two opposite edges of the first virtual quadrilateral region A are respectively provided with two colors of sub-pixels. Thus, the spacers of the four vertices of the first virtual quadrilateral region A can effectively support the FMM of the two colors of sub-pixels.
[0144] In some examples, as shown in FIG. 4, the plurality of sub-pixels 120 includes 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 first color sub-pixels 120A and third color sub-pixels 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 first color sub-pixels 120A and third color sub-pixels 120C arranged along the second direction; the arrangement of sub-pixels 120 in the fourth pixel group 144 is mirror-symmetrical 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-symmetrical 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. That is, the third pixel group 143 includes third color sub-pixels 120C and first color sub-pixels 120A arranged along the first direction and two second color sub-pixels 120B arranged along the second direction, and the fourth pixel group 144 includes two second color sub-pixels 120B arranged along the first direction and third color sub-pixels 120C and first color sub-pixels 120A arranged along the second direction. It can be seen that the types and quantities of sub-pixels in the first pixel group 141, the second pixel group 142, the third pixel group 143, and the fourth pixel group 144 are the same, but the arrangement manners are different.
[0145] In some examples, as shown in FIG. 4, the first spacer 131 is located in a spacing 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 in a spacing 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 in a spacing 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 a spacing 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. That is, the first spacer 131, the second spacer 132, the third spacer 133, and the fourth spacer 134 are in different environments.
[0146] In some examples, as shown in FIG. 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 FIG. 4, the first virtual quadrilateral region A is a parallelogram.
[0148] In some examples, as shown in FIG. 4, the length of the virtual edge on which the first vertex P11 and the second vertex P12 of the first virtual quadrilateral region A are located is greater than the size of the N first color sub-pixels 120A in the extension direction of the virtual edge, and N is greater than or equal to 2. That is, the range or size of the first virtual quadrilateral region can be set as needed.
[0149] In some examples, as shown in FIG. 4, the display substrate 100 includes a second virtual quadrilateral region B, a first spacer 131 and a second spacer 132 are respectively located at a fifth vertex P21 and a sixth vertex P22 of the second virtual quadrilateral region B, the fifth vertex P21 and the sixth vertex P22 are adjacent, or are located at two end points of the same edge of the second virtual quadrilateral region B. Two second color sub-pixels 120B are located at the two corners on which 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 the embodiments of the present disclosure, since the adjacent fifth vertex and the sixth vertex of the second virtual quadrilateral region are respectively provided with the first spacer and the second spacer, and the two corners on which the fifth vertex and the sixth vertex are located are provided with the two second color sub-pixels, for the two second color sub-pixels provided at the two corners on which the fifth vertex and the sixth vertex are located, one of the two second color sub-pixels is provided with the first spacer in the first direction, and the other is provided with the second spacer in the second direction. That is, 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 direction or the second direction, and one of the first spacer and the second spacer of the adjacent fifth vertex and the sixth vertex of the second virtual quadrilateral region cannot effectively support the FMM, since the displacement of the other direction is small, the other of the first spacer and the second spacer can still effectively support the FMM, thereby avoiding the FMM scratching the film layer structure, such as the organic light-emitting layer, of the plurality of sub-pixels on the display substrate, and further avoiding various defects.
[0151] In some examples, as shown in FIG. 4, the second virtual quadrilateral region B is in the shape of a parallelogram. The two corners on which the other two vertices of the second virtual quadrilateral region B are located are provided with two second color sub-pixels 120B.
[0152] In some examples, as shown in FIG. 4, the display substrate 100 includes a third virtual quadrilateral region C, a first spacer 131 and a second spacer 132 are respectively located at a seventh vertex P31 and an eighth vertex P32 of the third virtual quadrilateral region C, the seventh vertex P31 and the eighth vertex P32 are adjacent or are two end points of a same virtual side of the third virtual quadrilateral region C. Two third color sub-pixels 120C are located at two corners where the seventh vertex P31 and the eighth vertex P32 of the third virtual quadrilateral region C are located. It should be noted that the rectangular blocks shown as A, B, C and D in FIG. 4 are not actual structures, but schematically show the ranges of the above-mentioned various virtual quadrilateral regions; and the edges of the above-mentioned various virtual quadrilateral regions are defined by the above-mentioned vertices or the centers of the spacers, rather than the rectangular blocks shown as A, B, C and D.
[0153] In the display substrate provided in the embodiments of the present disclosure, since the first spacer and the second spacer are respectively arranged at the adjacent seventh vertex and eighth vertex of the third virtual quadrilateral region, and the two corners where the seventh vertex and the eighth vertex are located are provided with the two second color sub-pixels, for the two third color sub-pixels arranged at the two corners where the seventh vertex and the eighth vertex are located, one of the two third color sub-pixels is provided with the first spacer in the first direction, and the other is provided with the second spacer in the second direction. That is, 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 direction or the second direction, and one of the first spacer and the second spacer of the adjacent seventh vertex and eighth vertex of the third virtual quadrilateral region cannot effectively support the FMM, since the displacement of the misalignment in the other direction is small, the other of the first spacer and the second spacer can still effectively support the FMM, thereby avoiding the FMM scratching the film layer structure, such as the organic light-emitting layer, of the plurality of sub-pixels on the display substrate, and further avoiding various defects.
[0154] In some examples, as shown in FIG. 4, the third virtual quadrilateral region C has a shape of a parallelogram. The two corners where the other two vertices of the second virtual quadrilateral region B are located are provided with the two third color sub-pixels 120C.
[0155] In some examples, as shown in FIG. 4, the length of the virtual side where the seventh vertex P31 and the eighth vertex P32 of the third virtual quadrilateral region C are located is greater than the size of the N third color sub-pixels 120C in the extension direction of the virtual side, and the value of N is greater than or equal to 2. 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 FIG. 4, the display substrate 100 can further include a fourth virtual quadrilateral region D, a first spacer 131 and a second spacer 132 are respectively located at a ninth vertex P41 and a tenth vertex P42 of the fourth virtual quadrilateral region D, the ninth vertex P41 and the tenth vertex P42 are adjacent or are two end points of a same virtual side of the fourth virtual quadrilateral region D. Two second color sub-pixels 120B are located at 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 as A, B, C and D in FIG. 4 are not actual structures, but schematically show the ranges of the above-mentioned various virtual quadrilateral regions; and the edges of the above-mentioned various virtual quadrilateral regions are defined by the above-mentioned vertices or the centers of the spacers, rather than the rectangular blocks shown as A, B, C and D.
[0157] In the display substrate provided in the embodiments of the present disclosure, since the first spacer and the second spacer are respectively arranged at the adjacent ninth vertex and tenth vertex of the fourth virtual quadrilateral region, and the two second color sub-pixels are arranged at the two corners where the ninth vertex and the tenth vertex are located, for the two second color sub-pixels arranged at the two corners where the ninth vertex and the tenth vertex are located, one of the two second color sub-pixels is arranged with the first spacer in the first direction, and the other is arranged with the 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 for forming the third color sub-pixel and the display substrate are misaligned in the first direction or the second direction, and one of the first spacer and the second spacer of the adjacent ninth vertex and tenth vertex of the fourth virtual quadrilateral region cannot effectively support the FMM, since the displacement of the misalignment in the other direction is small, the other of the first spacer and the second spacer can still effectively support the FMM, thereby avoiding the FMM scratching the film layer structure, such as the organic light-emitting layer, of the plurality of sub-pixels on the display substrate, and further avoiding various defects.
[0158] In some examples, as shown in FIG. 4, the fourth virtual quadrilateral region D has a shape of a parallelogram. Two first color sub-pixels 120A are arranged at the corners where the other two vertices of the fourth virtual quadrilateral region D are located.
[0159] In some examples, as shown in FIG. 4, each spacer 130 is arranged adjacent to four sub-pixels 120, and there is no other sub-pixel between the spacer 130 and the adjacent sub-pixels 120. In this way, the spacer can be arranged in the region surrounded by the four sub-pixels, thereby fully utilizing the space on the display substrate.
[0160] In some examples, as shown in FIG. 4, each spacer 130 is located between corners of four sub-pixels 120 arranged adjacently, rather than between edges of adjacent sub-pixels.
[0161] In some examples, as shown in FIG. 4, 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 first color sub-pixels 120A, second color sub-pixels 120B, and third color sub-pixels 120C; each spacer 130 is located in a 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 includes a plurality of first color sub-pixels 120A and a plurality of third color sub-pixels 120C arranged alternately in a first direction, each first sub-pixel column 171 includes a plurality of first color sub-pixels 120A and a plurality of third color sub-pixels 120C arranged alternately in a second direction, the plurality of first sub-pixel rows 161 are arranged in the second direction, the plurality of first sub-pixel columns 171 are arranged in the first direction, and the first direction and the second direction intersect. The plurality of spacers 130 described above includes first spacers 131 and second spacers 132.
[0162] As shown in FIG. 4, the plurality of first sub-pixel rows 161 includes a plurality of first pixel spacer rows 1615, each first pixel spacer row 1615 includes a first spacer 131 located between a first color sub-pixel 120A and a third color sub-pixel 120C adjacent in the first direction; and the plurality of first sub-pixel columns 171 includes a plurality of first pixel spacer columns 1715, each first pixel spacer column 1715 includes a second spacer 132 located between a first color sub-pixel 120A and a third color sub-pixel 120C adjacent in the second direction.
[0163] In the display substrate provided in the embodiments of the present disclosure, since each first pixel spacer row 1615 includes the first spacers 131 located between the first color sub-pixels 120A and the third color sub-pixels 120C adjacent in the first direction, and each first pixel spacer column 1715 includes the second spacers 132 located between the first color sub-pixels 120A and the third color sub-pixels 120C adjacent in the second direction, for the first color sub-pixels, part of the first color sub-pixels are provided with the first spacers in the first direction, and part of the first color sub-pixels are provided with the second spacers in the second direction. When the FMM for forming the first color sub-pixels and the display substrate are misaligned in the first direction or the second direction, and one of the first spacers and the second spacers cannot effectively support the FMM, since the displacement of the misalignment in the other direction is small, the other one of the first spacers and the second spacers can still effectively support the FMM, thereby avoiding the FMM from scratching the film layer structure, such as the organic light-emitting layer, of multiple sub-pixels on the display substrate, and further avoiding various defects.
[0164] Similarly, for the third color sub-pixels, part of the third color sub-pixels are provided with the first spacers in the first direction, and part of the third color sub-pixels are provided with the second spacers in the second direction. When the FMM for forming the third color sub-pixels and the display substrate are misaligned in the first direction or the second direction, and one of the first spacers and the second spacers cannot effectively support the FMM, since the displacement of the misalignment in the other direction is small, the other one of the first spacers and the second spacers can still effectively support the FMM, thereby avoiding the FMM from scratching the film layer structure, such as the organic light-emitting layer, of multiple sub-pixels on the display substrate, and further avoiding various defects.
[0165] For example, the first direction and the second direction are perpendicular. Of course, the embodiments of the present disclosure include but are not limited to this, and the first direction and the second direction can also be non-perpendicular.
[0166] In some examples, as shown in FIG. 4, in the plurality of first sub-pixel rows 161, the plurality of first pixel spacer rows 1615 are unevenly distributed. For example, two adjacent first pixel spacer rows 1615 are directly adjacent, and another two adjacent first pixel spacer rows 1615 are arranged with one first sub-pixel row 161 in between. In this way, the display substrate can further reduce the risk of scratching.
[0167] In some examples, as shown in FIG. 4, in the plurality of first sub-pixel columns 171, the plurality of first pixel spacer columns 1715 are unevenly distributed. For example, two adjacent first pixel spacer columns 1715 are arranged with one first sub-pixel column 171 in between, and another two adjacent first pixel spacer columns 1715 are directly adjacent. In this way, the display substrate can further reduce the risk of scratching.
[0168] In some examples, as shown in FIG. 4, the first spacers 131 in two first pixel spacer rows 1615 adjacent in the second direction are staggered, i.e., the corresponding first spacers 131 in the two first pixel spacer rows 1615 adjacent in the second direction are not located on the same straight line extending along the second direction.
[0169] In some examples, as shown in FIG. 4, the second spacers 132 in the first pixel spacer columns 1715 adjacent in the first direction are staggered, i.e., the corresponding second spacers 132 in the first pixel spacer columns 1715 adjacent in the first direction are not located on the same straight line extending along the first direction.
[0170] In some examples, as shown in FIG. 4, the plurality of sub-pixels 120 includes a plurality of second sub-pixel rows 162 and a plurality of second sub-pixel columns 172, each second sub-pixel row 162 includes a plurality of second color sub-pixels 120B arranged alternately along the first direction, each second sub-pixel column 172 includes a plurality of second color sub-pixels 120B arranged alternately along the second direction, the plurality of second sub-pixel rows 162 are arranged along the second direction, and the plurality of second sub-pixel columns 172 are arranged along the first direction.
[0171] In some examples, as shown in FIG. 4, the plurality of second sub-pixel rows 162 includes a plurality of second pixel spacer rows 1625, each second pixel spacer row 1625 includes a second spacer 132 located between second color sub-pixels 120B adjacent in the first direction, and the plurality of second sub-pixel columns 172 includes a plurality of second pixel spacer columns 1725, each second pixel spacer column 1725 includes a first spacer 131 located between second color sub-pixels 120B adjacent in the second direction.
[0172] In the display substrate provided in the embodiments of the present disclosure, since each second pixel spacer row 1625 includes a second spacer 132 located between second color sub-pixels 120B adjacent in the first direction, and each second pixel spacer column 1725 includes a first spacer 131 located between second color sub-pixels 120B adjacent in the second direction, for the second color sub-pixels, part of the second color sub-pixels are provided with a second spacer in the first direction, and part of the second color sub-pixels are provided with a first spacer in the second direction. When the FMM used to form the second color sub-pixels and the display substrate are staggered in the first direction or the second direction, and one of the first spacers and the second spacers cannot effectively support the FMM, since the displacement of the other direction is small, the other one of the first spacers and the second spacers can still effectively support the FMM, thereby avoiding the FMM scratching the film layer structure of the plurality of sub-pixels on the display substrate, such as the organic light-emitting layer, and further avoiding various defects.
[0173] In some examples, as shown in FIG. 4, the plurality of first sub-pixel rows 161 and the plurality of second sub-pixel rows 162 are arranged alternately in the second direction, and the plurality of first sub-pixel columns 171 and the plurality of second sub-pixel columns 172 are arranged alternately in the first direction.
[0174] In some examples, as shown in FIG. 4, in the plurality of second sub-pixel rows 162, the plurality of second pixel spacer rows 1625 are distributed unevenly. In this way, the display substrate can further reduce the risk of scratching.
[0175] In some examples, as shown in FIG. 4, in the plurality of second sub-pixel columns 172, the plurality of second pixel spacer columns 1725 are distributed unevenly. In this way, the display substrate can further reduce the risk of scratching.
[0176] In some examples, as shown in FIG. 4, the second spacers 132 in two adjacent second pixel spacer rows 1625 in the second direction are misaligned, i.e., the corresponding second spacers 132 in two adjacent second pixel spacer rows 1625 in the second direction are not located on the same straight line extending in the second direction.
[0177] In some examples, as shown in FIG. 4, the first spacers 131 in the adjacent second pixel spacer columns 1725 in the first direction are misaligned, i.e., the corresponding first spacers 131 in the adjacent second pixel spacer columns 1725 in the first direction are not located on the same straight line extending in the first direction.
[0178] FIG. 5 is a plan view of another display substrate according to an embodiment of the present disclosure. As shown in FIG. 5, the display substrate 100 includes a substrate 110, a plurality of sub-pixels 120 on the substrate 110, and a plurality of spacers 130, each of which is located in a spacing region between adjacent sub-pixels 120. The plurality of sub-pixels 120 includes first color sub-pixels 120A, second color sub-pixels 120B, and third color sub-pixels 120C. The first color sub-pixels 120A are configured to emit light of a first color, the second color sub-pixels 120B are configured to emit light of a second color, and the third color sub-pixels 120C are configured to emit light of a third color. When forming the organic light-emitting layer of each sub-pixel 120, the plurality of spacers 130 can be used to support an extremely thin metal mask; in addition, the organic light-emitting layers of the first color sub-pixels 120A, the second color sub-pixels 120B, and the third color sub-pixels 120C are usually formed using different extremely thin metal masks.
[0179] For example, the first color can be red, the wavelength range of which can be 620-750 nm, the second color can be green, the wavelength range of which can be 495-570 nm, and the third color can be blue, the wavelength range of which can be 450-495 nm.
[0180] As shown in FIG. 5, the display substrate 100 includes a first virtual quadrilateral area A, and the plurality of spacers 130 includes a first spacer 131 and a second spacer 132; the shape of the first virtual quadrilateral area A is trapezoidal; one first spacer 131 and one second spacer 132 are respectively located at a first vertex P11 and a second vertex P12 of the first virtual quadrilateral area A, the first vertex P11 and the second vertex P12 are adjacent, or the first vertex P11 and the second vertex P12 are located at two ends of the same edge of the first virtual quadrilateral area A; one first spacer 131 and one second spacer 132 are respectively located at a third vertex P13 and a fourth vertex P14 of the first virtual quadrilateral area A, the third vertex P13 and the fourth vertex P14 are adjacent, or the third vertex P13 and the fourth vertex P14 are located at two ends of the same edge of the first virtual quadrilateral area A; four second color sub-pixels 120B are located at two corners of the first virtual quadrilateral area A where the first vertex P11, the second vertex P12, the third vertex P13 and the fourth vertex P14 are located.
[0181] In the display substrate provided in the embodiments of the present disclosure, since the first vertex, the second vertex, the third vertex and the fourth vertex of the first virtual quadrilateral area are respectively provided with the first spacer and the second spacer, and the two corners where the four vertices are located are provided with the four second color sub-pixels, for the four second color sub-pixels, the spacers are arranged in four directions. When the FMM used to form the second color sub-pixel and the display substrate are misaligned in the first direction or the second direction, and one of the four spacers cannot effectively support the FMM, the other spacers can still effectively support the FMM, thereby avoiding the FMM scratching the film layer structure, such as the organic light-emitting layer, of the plurality of sub-pixels on the display substrate, and further avoiding various defects.
[0182] In some examples, as shown in FIG. 5, the plurality of sub-pixels 120 includes a first pixel group 141 and a second pixel group 142; the first pixel group 141 includes the first color sub-pixel 120A and the third color sub-pixel 120C arranged along the first direction and the two second color sub-pixels 120B arranged along the second direction, and the second pixel group 142 includes the two second color sub-pixels 120B arranged along the first direction and the first color sub-pixel 120A and the third color sub-pixel 120C arranged along the second direction. It can be seen that the types and quantities of the sub-pixels in the first pixel group 141 and the second pixel group 142 are the same, but the arrangement manners are different.
[0183] In some examples, as shown in FIG. 5, the first spacers 131 and the third spacers 133 are located in the spacing regions surrounded by the first color sub-pixels 120A, the second color sub-pixels 120B and the third color sub-pixels 120C in the first pixel group 141, and the second spacers 132 and the fourth spacers 134 are located in the spacing regions surrounded by the first color sub-pixels 120A, the second color sub-pixels 120B and the third color sub-pixels 120C in the second pixel group 142.
[0184] In the display substrate provided in this example, for the first color sub-pixels in the first pixel group, the first spacers are located on one side of the first color sub-pixels in the first direction, and for the first color sub-pixels in the second pixel group, the second spacers are located on one side of the first color sub-pixels in the second direction. When the FMM used to form the first color sub-pixels and the display substrate are misaligned in the first direction or the second direction, and one of the first spacers and the second spacers cannot effectively support the FMM, due to the smaller displacement of the misalignment in the other direction, the other one of the first spacers and the second spacers can still effectively support the FMM, thereby avoiding the FMM from scratching the film layer structure of the plurality of sub-pixels on the display substrate, and further avoiding various malfunctions.
[0185] Similarly, for the third color sub-pixels in the first pixel group, the first spacers are located on one side of the third color sub-pixels in the first direction, and for the third color sub-pixels in the second pixel group, the second spacers are located on one side of the third color sub-pixels in the second direction. When the FMM used to form the third color sub-pixels and the display substrate are misaligned in the first direction or the second direction, and one of the first spacers and the second spacers cannot effectively support the FMM, due to the smaller displacement of the misalignment in the other direction, the other one of the first spacers and the second spacers can still effectively support the FMM, thereby avoiding the FMM from scratching the film layer structure of the plurality of sub-pixels on the display substrate, and further avoiding various malfunctions.
[0186] Similarly, for the second color sub-pixels in the first pixel group, the first spacers are located on one side of the second color sub-pixels in the second direction, and for the second color sub-pixels in the second pixel group, the second spacers are located on one side of the second color sub-pixels in the first direction. When the FMM used to form the second color sub-pixels and the display substrate are misaligned in the first direction or the second direction, and one of the first spacers and the second spacers cannot effectively support the FMM, due to the smaller displacement of the misalignment in the other direction, the other one of the first spacers and the second spacers can still effectively support the FMM, thereby avoiding the FMM from scratching the film layer structure of the plurality of sub-pixels on the display substrate, and further avoiding various malfunctions.
[0187] FIG. 6A is a schematic view of a cross section of a spacer; FIG. 6B is a schematic view of a plan of another spacer according to an embodiment of the present disclosure; and FIG. 6C is a schematic view of a cross section of another spacer along line AB in FIG. 6B according to an embodiment of the present disclosure. As shown in FIG. 6A, since the spacer is usually formed of an organic material, there is a ramping at the edge of the spacer, so that the height of the edge portion of the spacer is lower, and the supporting effect is weaker. As shown in FIG. 6B and FIG. 6C, the spacer 130 includes a plurality of sub-spacer portions 1305 arranged at intervals. Thus, by arranging the spacer as a plurality of sub-spacer portions 1305 arranged at intervals, the edge portion of the spacer 130 also has a higher height, so that the edge portion of the spacer also has a better supporting effect. It should be noted that the plurality of sub-spacer portions described above can share a base, or can be independently arranged. The embodiments of the present disclosure are not limited here. In addition, the spacer shown in FIG. 6B and FIG. 6C can be applied to any one of the spacers in FIG. 1 to FIG. 5.
[0188] For example, as shown in FIG. 6B, the spacer 130 includes four sub-spacer portions 1305 arranged at intervals, and the four sub-spacers 1305 form a 2*2 matrix. Of course, the embodiments of the present disclosure include but are not limited to this. FIG. 7 is a schematic view of a display device according to an embodiment of the present disclosure. As shown in FIG. 7, the display device 500 includes the display substrate 100 provided by any one of the examples described above. Thus, the display device can also effectively avoid the FMM scratching the film layer structure of the plurality of sub-pixels on the display substrate, such as the organic light-emitting layer, and further avoid various malfunctions.
[0189] In some examples, the display device can adopt a stacked light-emitting technology, so as to have a higher light-emitting brightness and a longer service life.
[0190] In some examples, the display device described above can be any product or component having a display function, such as a television, a digital camera, a mobile phone, a watch, a tablet computer, a notebook computer, a navigator, etc., and the embodiments of the present disclosure are not limited thereto.
[0191] The following points need to be explained:
[0192] (1) In the drawings of the embodiments of the present disclosure, only the structures related to the embodiments of the present disclosure are involved, and other structures can be referred to the general design.
[0193] (2) The features in the same embodiment and different embodiments of the present disclosure can be combined with each other without conflict.
