For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0042] In the process of preparing the display panel, a display panel motherboard 10 including a plurality of panel areas 200 is usually provided, and each film layer of the display panel is prepared at the stage of the display panel motherboard 10, and then the display panel motherboard 10 is cut so that each panel area 200 forms a single display panel, that is, the area where the panel area 200 is located is the area where the display panel is subsequently formed. The display panel motherboard 10 includes a second substrate 400, and a structure for supporting the second substrate 400 is usually provided in the display panel, such as a pixel definition layer 240, a support column 250, etc., but the support force for the second substrate 400 in the gap between two adjacent panel areas 200 is insufficient, resulting in the second substrate 400 being easily deformed at the portion corresponding to the gap between the two panel areas 200, and the deformation extends to the panel area 200 to affect the display effect of the final display panel, so that display defects such as Newton rings appear on the display panel.

[0043] In order to solve the above technical problems, this application is proposed. In order to better understand this application, Figures 1 to 17 The display panel motherboard, the mask plate and the method for preparing the display panel motherboard according to the embodiments of the present application are described in detail.

[0044] Please also read Figure 1 to Figure 2 , Figure 1 A schematic diagram of the structure of a display panel motherboard 10 provided in an embodiment of the present application is shown in FIG. Figure 2 yes Figure 1 Cross-sectional view at AA in the middle.

[0045] like Figure 1 and Figure 2As shown, an embodiment of the first aspect of the present application provides a display panel motherboard 10, which includes: a first substrate 100; a plurality of panel areas 200, which are arranged on one side of the first substrate 100, and the plurality of panel areas 200 are distributed at intervals; at least one supporting component 300, which is arranged on one side of the first substrate 100, and the supporting component 300 includes a supporting structure 310, and at least one supporting structure 310 is located between at least two adjacent panel areas 200.

[0046] In the display panel motherboard 10 provided in the embodiment of the present application, the display panel motherboard 10 includes a first substrate 100, a panel area 200, a support assembly 300 and a cutting area P1, and a plurality of panel areas 200 are spaced apart and distributed on one side of the first substrate 100, and a single panel area 200 is used to form a single display panel. The support assembly 300 includes a support structure 310, and at least one support structure 310 is located between two adjacent panel areas 200. When the second substrate 400 is subsequently set, the support structure 310 can provide support to the second substrate 400 to improve display problems such as Newton rings caused by deformation of the second substrate 400, and can improve the display effect of the display panel.

[0047] Optionally, the display panel further includes a cutting area P1, which is located between the support structure 310 and the panel area 200. When the motherboard is cut along the cutting area to form a single display panel, the support structure 310 can be removed to improve the influence of the support structure 310 on the size of the display panel frame area, thereby further improving the display effect of the display panel.

[0048] The display panel motherboard 10 can be cut in the cutting area P1 to form multiple display panels. The cutting area P1 is an area used for subsequent cutting and does not constitute a specific structural limitation on the display panel motherboard 10 of the present application. Figure 1 Only part of the cutting area P1 is shown in the figure. Other cutting areas P1 can also be set in the gap on the side of the support structure 310 on the display panel motherboard 10 away from the panel area 200. Optionally, each panel area 200 is correspondingly provided with a cutting area P1, and the panel area 200 is cut in the cutting area P1 to form a single display panel.

[0049] To simplify the content, each of the following embodiments has a cutting area P1 , and the cutting area P1 is located between the support structure 310 and the panel area 200 .

[0050] Optionally, at least one supporting structure 310 may be provided between at least two adjacent panel areas 200. For example, a supporting structure 310 may be provided between any two adjacent panel areas 200, or a supporting structure 310 may be provided between a group of two adjacent panel areas 200, for example, the panel areas 200 are arranged in two rows, and each row is provided with a plurality of panel areas 200, and the supporting structure 310 is located between the two rows.

[0051] Optional, such as Figure 2 As shown, the motherboard of the display panel further includes a second substrate 400, which is covered on the side of the support structure 310 away from the first substrate 100. Due to the existence of the support structure 310, the deformation of the second substrate 400 in the panel area 200 can be improved, thereby improving the display effect of the display panel.

[0052] The second substrate 400 may be a cover plate or other structures. For example, the second substrate 400 is a glass cover plate.

[0053] like Figure 2 As shown, an array film layer is disposed on one side of the first substrate 100. The array film layer is a related film layer in the related art, such as an active layer, a gate layer, a source-drain layer, an insulating layer, etc., which will not be described in detail here. After the metal layer in the array film layer is patterned, there may or may not be a metal layer between the two panel areas 200.

[0054] Optionally, the sizes of the plurality of panel areas 200 may be the same. Alternatively, the sizes of at least two of the plurality of panel areas 200 may be different. Optionally, the shapes of the plurality of panel areas 200 may be the same. Alternatively, the shapes of at least two of the plurality of panel areas 200 may be different.

[0055] In some optional embodiments, please continue to refer to Figure 1 The panel area 200 includes a first panel area 201 and a second panel area 202, and the first panel area 201 and the second panel area 202 have different shapes. By setting the first panel area 201 and the second panel area 202 of different shapes on the display panel motherboard 10, display panels of different shapes can be prepared, which can enrich the setting methods of the display panel.

[0056] Optionally, the orthographic projection area of ​​the first panel region 201 on the first substrate 100 is smaller than the orthographic projection area of ​​the second panel region 202 on the first substrate 100. That is, the sizes of the first panel region 201 and the second panel region 202 having different shapes may be different.

[0057] There are many ways to arrange the multiple panel areas 200. The multiple panel areas 200 can be arranged in disorder, or the multiple panel areas 200 can be arranged in rows and columns. For example, when the multiple panel areas 200 include the above-mentioned first panel area 201 and the second panel area 202, the first panel area 201 is provided with multiple, and the multiple first panel areas 201 are spaced apart along the first direction Y to form a first sub-area L1, and at least one first sub-area L1 is provided along the second direction X; the second panel area 202 is provided with multiple, and the multiple second panel areas 202 are spaced apart along the first direction Y to form a second sub-area L2; and at least one second sub-area L2 is provided along the second direction X; wherein the first direction Y intersects with the second direction X. Specifically, as Figure 1 As shown, two first sub-areas L1 are provided, three second sub-areas L2 are provided, and the first direction Y is perpendicular to the second direction X.

[0058] In these optional embodiments, a plurality of first panel areas 201 of the same size are arranged at intervals to form a first sub-area L1, and a plurality of second panel areas 202 of the same size are arranged at intervals to form a second sub-area L2, so that the arrangement of the plurality of panel areas 200 is more scientific and regular, and a greater number of panel areas 200 can be set. When the second substrate 400 is subsequently set, the force on the panels in the same row is more balanced, which can better improve the display problem of Newton rings and improve the display effect of the display panel.

[0059] Optionally, along the first direction Y, a plurality of first panel areas 201 are arranged at equal intervals; a plurality of second panel areas 202 are arranged at equal intervals, so that the forces on the first panel areas 201 and the second panel areas 202 are more balanced and arranged more evenly.

[0060] Optionally, each first panel area 201 in the first sub-area L1 is arranged in one-to-one correspondence with each second panel area 202 in the second sub-area L2, so that the forces on the first panel area 201 and the second panel area 202 are more balanced.

[0061] Optionally, the first sub-region L1 and the second sub-region L2 are arranged side by side along the second direction X, and the center of the first panel area 201 and the corresponding center of the second panel area 202 are arranged at intervals along the second direction X, that is, the center of the first panel area 201 and the center of the second panel area 202 correspond to each other, and the first panel area 201 and the second panel area 202 are arranged in the center, which can further improve the force on the first panel area 201 and the second panel area 202.

[0062] In other embodiments, a plurality of first panel areas 201 in the first sub-area L1 are arranged correspondingly to a second panel area 202 in the second sub-area L2. Of course, the plurality here may not be an integer.

[0063] In some optional embodiments, please continue to refer to Figure 1 The support structure 310 includes a first support portion 311 , and the first support portion 311 is located between the adjacent first sub-region L1 and the second sub-region L2 .

[0064] In these optional embodiments, a first supporting portion 311 is provided between the first sub-region L1 and the second sub-region L2, which can improve the Newton ring problem caused by the different shapes of the first panel area 201 and the second panel area 202, resulting in different supporting forces of the first panel area 201 and the second panel area 202 on the second substrate 400.

[0065] There are many ways to set the first support portion 311, for example, Figure 1 As shown, the first support portion 311 is extended along the first direction Y and is arranged corresponding to the plurality of first panel areas 201, which can simplify the shape of the first support portion 311. Figure 3 As shown, a plurality of first support portions 311 are provided, and the plurality of first support portions 311 are arranged at intervals along the first direction Y, and each first support portion 311 is located between the corresponding first panel areas 201 and second panel areas 202, and each first support portion 311 is used to improve the display problem between each first panel area 201 and each second panel area 202.

[0066] Optionally, the width of the first support portion 311 is 0.4 mm to 0.5 mm. For example, the width of the first support portion 311 is 0.4 mm, 0.43 mm, 0.45 mm, 0.46 mm or 0.5 mm, etc. This can improve the supporting capacity of the first support portion 311 due to its insufficient width, and can also improve the space occupied by the first support portion 311 due to its excessive width, which affects the number of panel areas 200 on the display panel motherboard 10. When the first support portion 311 extends along the first direction Y, the width direction of the first support portion 311 can be the second direction X, that is, the width of the first support portion 311 in the second direction X is 0.4 mm to 0.5 mm.

[0067] Optionally, the number of the first sub-region L1 may be one, and the first sub-region L1 is located on one side of the second sub-region L2 in the second direction X; or, the number of the first sub-region L1 is two, and the two first sub-regions L1 are located on both sides of the plurality of second sub-regions L2 in the second direction X. Of course, in other embodiments, more than two may be provided, and the adjustment may be made according to actual conditions.

[0068] In some optional embodiments, such as Figure 4As shown, along the first direction Y, there is a first distance between two adjacent first panel areas 201, and a second distance between two adjacent second panel areas 202, the first distance is greater than the second distance, and the support structure 310 further includes a second support portion 312, which is located between at least two adjacent first panel areas 201 in the first sub-area L1.

[0069] In the embodiment provided in the present application, the distance between two adjacent first panel areas 201 is relatively large, and the supporting force between the two adjacent first panel areas 201 is insufficient, which causes the second substrate 400 to be easily deformed. By setting a second supporting portion 312 between the two adjacent first panel areas 201, the supporting force for the second substrate 400 can be increased, and the deformation of the second substrate 400 can be improved, thereby changing the display problems such as Newton rings caused by the deformation of the second substrate 400.

[0070] Optionally, the number of the first panel areas 201 in the first sub-area L1 may be more than three, more than two gaps may be formed between more than two first panel areas 201, and the second support portion 312 may be disposed in the gap between any two first panel areas 201. Alternatively, the second support portion 312 is disposed between at least one group of two adjacent first sub-areas L1.

[0071] When the number of the second supporting portions 312 disposed between two adjacent first panel areas 201 can be one or more, for example, Figure 4 As shown, at least one second support portion 312 may be disposed between two adjacent first panel areas 201 in the first sub-area L1, or as shown in FIG. Figure 5 As shown, more than two second supporting portions 312 are located between two adjacent first panel areas 201 .

[0072] Optional, such as Figure 5 As shown, when two or more second support parts 312 are provided between two adjacent first panel areas 201, the spacing between two adjacent second support parts 312 is 3 mm to 5 mm. For example, the spacing between two adjacent second support parts 312 is 3 mm, 3.6 mm, 4.0 mm, 4.8 mm, 5 mm, etc., to improve the problem that the spacing between two adjacent second support parts 312 is too small and difficult to manufacture, and the problem that the spacing between two adjacent second support parts 312 is too large and causes insufficient support force.

[0073] Optionally, the width of the second support portion 312 is 0.4 mm to 0.5 mm. For example, the width of the second support portion 312 in the first direction Y is 0.4 mm, 0.43 mm, 0.45 mm, 0.46 mm, 0.5 mm, etc. This can improve the supporting capacity of the second support portion 312 due to its insufficient width, and can also improve the space occupied by the second support portion 312 due to its excessive width, which affects the number of panel areas 200 on the display panel motherboard 10.

[0074] Optionally, the area where multiple first panel areas 201 are located is the first area, that is, at least one first sub-area L1 constitutes the first area; the first area is provided with at least one, and the area where multiple second panel areas 202 are located is the second area, that is, at least one second sub-area L2 constitutes the second area; the first area is located on one side of the second area, and the second support portion 312 is located in the first area.

[0076] In these optional embodiments, the first area where the first panel area 201 is located is located on one side of the second area where the second panel area 202 is located, and the second support portion 312 is located in the first area to improve the problem of insufficient supporting force caused by the large distance between two adjacent first panel areas 201 in the first area.

[0077] Optionally, the number of the first regions may be one, and the first region is located on one side of the second region in the second direction X or in the first direction Y. Alternatively, the number of the first regions may be two, and the two first regions are located on both sides of the second region in the second direction X or in the first direction Y.

For example, the number of the support components 320 is two, and the two support components 320 can be respectively arranged on two sides of the central area Q1 in the first direction Y or the second direction X. Or, as Figure 5 As shown, the support members 320 may be disposed around the central area Q1.

For example, the distance between the support structure 310 and the adjacent packaging unit 210 is 1 mm, 3 mm, 5 mm, 6 mm, 10 mm, etc.

[0086] Optionally, the orthographic projection of the packaging unit 210 on the first substrate 100 is a ring, and the shape of the packaging unit 210 is adapted to the shape of the panel area 200. For example, the packaging unit 210 can be determined based on the morphology of the orthographic projection of the panel area 200 on the first substrate 100, such as the inner and outer boundaries of the ring-shaped packaging unit 210 are circular or elliptical, the inner and outer boundaries of the ring-shaped packaging unit 210 are rectangular ring structures, or the inner and outer boundaries of the ring are runway-shaped, etc.

[0087] In these optional embodiments, the packaging unit 210 is used to encapsulate the light-emitting elements in the panel area 200, and the distance between the support structure 310 and the adjacent packaging unit 210 is less than or equal to 10 mm, so that the distance between the support structure 310 and the panel area 200 is closer, and the support structure 310 can provide better support to the second substrate 400, thereby better improving the display effect of the panel area 200 affected by the deformation of the second substrate 400.

[0088] Optionally, the material of the packaging unit 210 may include glass powder, and the packaging unit 210 and the second substrate 400 are sintered and connected by the glass powder to improve the sealing effect.

[0089] Optionally, the packaging unit 210 includes a first packaging unit 211 corresponding to the first panel area 201, and the distance between the support structure 310 and the adjacent first packaging unit 210 is 3 mm to 5 mm. For example, the distance between the support structure 310 and the adjacent first packaging unit 211 is 3 mm, 3.2 mm, 3.8 mm, 4.4 mm, 5 mm, etc., to improve the packaging effect of the first packaging unit 211 affected by the small distance between the support structure 310 and the first packaging unit 211, and also to improve the space waste caused by the large distance between the support structure 310 and the first packaging unit 211.

[0090] Optionally, the packaging unit 210 includes a second packaging unit 212 corresponding to the second panel area 202, and the distance between the support structure 310 and the adjacent second packaging unit 212 is 7 mm to 8 mm. For example, the distance between the support structure 310 and the adjacent second packaging unit 212 is 7 mm, 7.2 mm, 7.5 mm, 7.8 mm, 8 mm, etc., so as to improve the packaging effect of the first packaging unit 211 affected by the small distance between the support structure 310 and the second packaging unit 212, and also to improve the space waste caused by the large distance between the support structure 310 and the second packaging unit 212.

[0091] Optionally, the orthographic projection area of ​​the first panel area 201 on the first substrate 100 is smaller than the orthographic projection area of ​​the second panel area 202 on the first substrate 100, and the distance between the support structure 310 and the adjacent first package unit 211 is smaller than the distance between the support structure 310 and the adjacent second package unit 212, that is, the distance between the support structure 310 and the first package unit 211 in the first panel area 201 with a smaller area is smaller, so as to improve the influence of the support structure 310 on the first package unit 211 caused by manufacturing errors. In addition, since the area of ​​the first panel area 201 is small, the distance between two adjacent first panel areas 201 can be set larger, and the supporting effect is poor, so the distance between the support structure 310 and the first package unit 211 can be appropriately smaller.

[0092] Optional, please continue to Figure 7 The panel area 200 further includes a binding area 220, which is located on a side of the packaging unit 210 away from the panel area 200. When the support structure 310 and the binding area 220 are located on the same side of the same panel area 200, the distance between the support structure 310 and the corresponding binding area 220 is 1 mm to 2 mm. For example, the distance between the support structure 310 and the corresponding binding area 220 is 1 mm, 1.2 mm, 1.3 mm, 1.5 mm, 1.8 mm, 2 mm, etc., to improve the influence of the support structure 310 on the binding area 220.

[0093] Optionally, the binding area 220 is used to bind devices such as flexible circuits.

[0094] In some optional embodiments, such as Figure 8 As shown, along the first direction Y, there is a first gap between two adjacent first panel areas 201, and the width of the first gap in the first direction Y is the third distance; along the first direction Y, there is a second gap between two adjacent second panel areas 202, and the width of the second gap in the first direction Y is the fourth distance, and the third distance is greater than the fourth distance; the support structure 310 is located in the first gap.

[0095] In these optional embodiments, the third distance is greater than the fourth distance, that is, the width of the first gap is greater than the width of the second gap, so that the support force of the first gap at the position of the second substrate 400 is insufficient, and the second substrate 400 is easily deformed at the position corresponding to the first gap. The support structure 310 is located in the first gap, which can improve the problem of easy deformation of the second substrate 400 due to the excessive distance between the two adjacent first panel areas 201.

[0096] Optionally, the support structure 310 in the first gap may be the second support portion 312. When the support assembly 300 includes the second support portion 312, the support assembly 300 may also include the first support portion 311 and / or the third support portion 313, or the support assembly 300 may not include the first support portion 311 and / or the third support portion 313. Optionally, the support structure 310 may include one or both of the first support portion 311 and the second support portion 312.

[0097] The support structure 310 in the first gap is arranged in the same manner as the second support portion 312. For example, at least one support structure 310 is arranged in the first gap. Alternatively, more than two support structures 310 are arranged between two adjacent first panel areas 201. That is, one or more support structures 310 may be arranged between two adjacent first panel areas 201.

[0098] Optionally, when more than two support structures 310 are provided between two adjacent first panel areas 201, the spacing between two adjacent support structures 310 is 3 mm to 5 mm. For example, the spacing between two adjacent support structures 310 is 3 mm, 3.6 mm, 4.0 mm, 4.8 mm, 5 mm, etc., to improve the problem that the spacing between two adjacent support structures 310 is too small and difficult to prepare, and the spacing between two adjacent support structures 310 is too large and causes insufficient support force.

[0099] Optionally, the width of the support structure 310 is 0.4 mm to 0.5 mm. For example, the width of the support structure 310 is 0.4 mm, 0.43 mm, 0.45 mm, 0.46 mm, and 0.5 mm. This can improve the supporting capacity of the support structure 310 due to its insufficient width, and can also improve the space occupied by the support structure 310 due to its excessive width, which affects the number of panel areas 200 on the display panel motherboard 10.

[0100] Optional, such as Fig. 9As shown, the display panel motherboard 10 has a plurality of packaging units 210, and the packaging units 210 include the first packaging units 210 arranged corresponding to the first panel area 201, and the distance between the support structure 310 and the adjacent first packaging units 210 is 3 mm to 5 mm. For example, the distance between the support structure 310 and the adjacent first packaging units 211 is 3 mm, 3.2 mm, 3.8 mm, 4.4 mm, 5 mm, etc., so as to improve the packaging effect of the first packaging unit 211 affected by the small distance between the support structure 310 and the first packaging unit 211, and also improve the space waste caused by the large distance between the support structure 310 and the first packaging unit 211.

[0101] Optionally, please refer to the above, the orthographic projection of the packaging unit 210 on the first substrate 100 is located within the orthographic projection of the corresponding panel area 200 on the first substrate 100, and the orthographic projection of the packaging unit 210 on the first substrate 100 is a ring, and the shape of the ring can be determined according to the morphology of the orthographic projection of the panel area 200 on the first substrate 100, for example, the inner and outer boundaries of the ring are circular or elliptical, the inner and outer boundaries of the ring are rectangular ring structures, or the inner and outer boundaries of the ring are runway-shaped, etc.

By arranging the support structure 310 in the edge area Q2, a more stable support can be provided from the edge area Q2 to the second substrate 400, thereby improving the problem that the second substrate 400 is easily deformed in the edge area Q2.

[0104] In some optional embodiments, the width of the support structure 310 is 0.4 mm to 0.5 mm, for example, the width of the support structure 310 is 0.4 mm, 0.43 mm, 0.45 mm, 0.46 mm, 0.5 mm. This can improve the supporting capacity of the support structure 310 due to its insufficient width, and can also improve the space occupied by the support structure 310 due to its excessive width, which affects the number of panel areas 200 on the display panel motherboard 10.

[0105] There are many ways to set the material of the support structure 310, for example, Figure 2 and Fig.10 As shown, the display panel motherboard 10 includes a packaging unit 210, and the materials of the support structure 310 and the packaging unit 210 both include glass powder. The support structure 310 and the packaging unit 210 both contain the same components, so that the support structure 310 can not only have sufficient rigidity and strength, but also the support structure 310 and the packaging unit 210 can be prepared and formed in the same process steps, which can simplify the preparation process of the support structure 310. The packaging unit 210 can be a packaging frame structure, and the second substrate 400 and the packaging unit 210 can be sintered and connected.

The material of the support structure 310 is the same as that of the support column 250, so that the support structure 310 and the support column 250 can be prepared and formed in the same process step, which can simplify the preparation process of the support structure 310.

[0107] In other embodiments, the material of the support structure 310 may also include metal, organic material, etc., as long as the support structure 310 has sufficient height and supporting force.

[0110] Optionally, the pixel definition layer 240 has a first surface 241 away from the first substrate 100, and the distance between the first surface 241 and the first substrate 100 is a first spacing distance; the support structure 310 has a second surface 310a away from the first substrate 100, and the distance between the second surface 310a and the first substrate 100 is a second spacing distance; the difference between the first spacing distance and the second spacing distance is less than or equal to 350nm. For example, the difference between the first spacing distance and the second spacing distance is 40nm, 150nm, 220nm, 320nm, 350nm, etc.

[0111] In these optional embodiments, the difference between the first spacing distance and the second spacing distance is less than or equal to 350 nm, that is, the height of the pixel definition layer 240 relative to the first substrate 100 and the height of the support structure 310 relative to the first substrate 100 are close, and the height of the film layer in the panel area 200 and the height of the support structure 310 are close, so that the support structure 310 and the pixel definition layer 240 can cooperate to support the second substrate 400, and can provide more balanced support to the second substrate 400, thereby better improving the deformation problem of the second substrate 400.

[0112] Optionally, the first spacing distance is greater than or equal to the second spacing distance, so as to improve the yield of the display panel formed in the panel area 200 due to the large spacing between the second substrate 400 and the pixel definition layer 240 due to the large second spacing distance.

[0113] Optionally, the difference between the first spacing distance and the second spacing distance is greater than or equal to 50 nm. For example, the difference between the first spacing distance and the second spacing distance is 10 nm, 14 nm, 23 nm, 38 nm, 50 nm, etc., so that the first spacing distance and the second spacing distance are closer, and a more balanced support can be provided to the second substrate 400, and the deformation problem of the second substrate 400 can be better improved.

For example, the difference between the third spacing distance and the second spacing distance is 40nm, 150nm, 220nm, 320nm, 350nm, etc.

[0115] In these optional embodiments, when the display panel motherboard 10 includes support columns 250, the support columns 250 of the panel area 200 are used to support the second substrate 400, and the height difference between the support structure 310 and the first substrate 100 is closer to the height difference between the support columns 250 and the first substrate 100, which can make the height of the film layer in the panel area 200 and the height of the support structure 310 closer, so that the support structure 310 and the pixel definition layer 240 can cooperate to support the second substrate 400, and can provide more balanced support to the second substrate 400, thereby better improving the deformation problem of the second substrate 400.

[0116] Optionally, the third spacing distance is greater than or equal to the second spacing distance, so as to improve the yield of the display panel formed in the panel area 200 due to the large spacing between the second substrate 400 and the supporting pillar 250 caused by the large second spacing distance.

[0117] Optionally, the difference between the third spacing distance and the second spacing distance is less than or equal to 50 nm. For example, the difference between the third spacing distance and the second spacing distance is 10 nm, 14 nm, 23 nm, 38 nm, 50 nm, etc., so that the third spacing distance and the second spacing distance are closer, which can provide more balanced support to the second substrate 400 and better improve the deformation problem of the second substrate 400.

[0118] Optionally, please refer to the above, the display panel motherboard 10 may further include a second substrate 400, the second substrate 400 is located on the side of the pixel definition layer 240 away from the first substrate 100, and the second substrate 400 covers the support structure 310. Optionally, a film layer such as a polarizer may be provided on the side of the second substrate 400 away from the pixel definition layer 240. Optionally, the second substrate 400 covers a plurality of panel areas 200, that is, the plurality of panel areas 200 share the same second substrate 400, and a plurality of display panels are formed by cutting the display panel motherboard on the side of the second substrate 400 away from the first substrate 100.

[0119] In the actual production process, the evaporated organic light-emitting material and the electrode part are prepared as a whole layer, such as a common layer and a cathode layer. Then the organic light-emitting material and the electrode material are stacked on the side of the pixel definition layer 240 or the support column 250 in the above embodiment away from the first substrate 100. Due to their relatively small thickness and process fluctuations, the judgment is mainly based on the height of the side of the pixel definition layer 240 or the support column 250 away from the first substrate 100 and the side of the support structure 310 away from the first substrate 100.

[0120] Of course, in a specific embodiment, since the cathode layer is located on the side of the common layer away from the substrate, and the cathode layer is away from the fourth surface of the first substrate 100, the distance between the fourth surface and the first substrate 100 is the fifth spacing distance; the support structure 310 has a second surface 310a away from the first substrate 100, and the distance between the second surface 310a and the first substrate 100 is the second spacing distance; the difference between the fifth spacing distance and the second spacing distance is less than or equal to 350nm.

[0121] Optionally, the difference between the fifth spacing distance and the second spacing distance is less than or equal to 50 nm. For example, the difference between the fifth spacing distance and the second spacing distance is 10 nm, 14 nm, 23 nm, 38 nm, 50 nm, etc., so that the fifth spacing distance and the second spacing distance are closer, which can provide more balanced support to the second substrate 400 and better improve the deformation problem of the second substrate 400.

[0122] In some optional embodiments, such as Figures 11 to 15 As shown, a plurality of panel areas 200 are distributed in an array along the first direction Y and the second direction X, and the support structure 310 is located between two adjacent panel areas 200 along the first direction Y and / or the second direction X. The support structure 310 can provide support to the second substrate 400 between two adjacent panel areas 200 along the first direction Y and / or the second direction X.

[0123] Optionally, the panel area 200 has a first shaped edge 260, the support structure 310 has a second shaped edge 310b facing the corresponding adjacent panel area 200, and the first shaped edge 260 and the second shaped edge 310b are conformal. In these optional embodiments, the first shaped edge 260 and the second shaped edge 310b are conformal, that is, the first shaped edge 260 and the second shaped edge 310b are arranged at equal intervals, so that the shape of the support structure 310 is more compatible with the shape of the panel area 200, which can better improve the problem of easy deformation of the side cover plate of the panel area 200.

[0124] There are many ways to set the first profiled edge 260, for example, Fig.11 As shown, the panel area 200 is circular, and the first profiled edge 260 is arc-shaped. Fig.13 As shown, the panel area 200 is in a racetrack shape, and the first profiled edge 260 may also be in an arc shape.

The second irregular edge 310b is adapted to the shape of the first irregular edge 260, and the second irregular edge 310b can also be in an arc shape, an arc shape or a folded line shape. In other embodiments, the first irregular edge 260 and the second irregular edge 310b can be a combination of a straight line and a curve.

[0125] Optionally, the support structure 310 has two second irregular edges 310b facing the corresponding adjacent panel areas 200 located on both sides thereof. Fig.11 As shown, the four support structures 310 located in the clearance gap Q3 can be integrally arranged, and when the two panel areas 200 are located on both sides of the support structure 310 in the first direction Y, the support structure 310 has two second special-shaped edges 310b located on both sides of itself in the first direction Y. Alternatively, when the two panel areas 200 are located on both sides of the support structure 310 in the second direction X, the support structure 310 has two second special-shaped edges 310b located on both sides of itself in the second direction X. The support structure 310 can improve the force of the cover plate near the panel areas 200 located on both sides thereof, and better improve the problem of easy deformation of the cover plate.

[0126] Optional, such as Fig.11 and Fig.12 As shown, one or more support structures 310 are located between two adjacent panel areas 200. By providing one or more support structures 310 between two adjacent panel areas 200, the problem of easy deformation caused by uneven force on the cover plate can be better improved.

[0127] Optionally, four panel areas 200 are enclosed to form a clearance gap Q3, and at least one support structure 310 is located in the clearance gap Q3. The pixel definition layer 240 is arranged in the four adjacent panel areas 200, and each of them can provide support to the cover plate. However, the clearance gap Q3 formed by the four adjacent panel areas 200 is easy to deform the cover plate due to lack of support. The support structure 310 is arranged in the clearance gap Q3 to improve the problem of easy deformation of the cover plate.

[0128] Optionally, four support structures 310 are located in the clearance gap Q3, and each support structure 310 has a second special-shaped edge 310b facing each panel area 200. This can better improve the problem of easy deformation of the cover plate.

[0129] In some optional embodiments, the height of the support structure 310 is 4 mm to 6 mm. For example, the height of the support structure 310 is 4 mm, 4.3 mm, 4.5 mm, 4.8 mm, 5.3 mm, 5.6 mm, 5.9 mm, 6 mm, etc., to improve the problem that the height of the support structure 310 is too small, affecting its supporting capacity, and the height of the support structure 310 is too large, resulting in a gap between the panel area 200 and the cover plate.

[0130] In some optional embodiments, such as Figure 2 and Fig.10 As shown, there is a second spacing distance between the surface of the support structure 310 away from the substrate and the first substrate 100; the display panel motherboard 10 also includes a plurality of packaging units 210, the orthographic projection of the packaging unit 210 on the first substrate 100 is located within the orthographic projection of the corresponding panel area 200 on the first substrate 100, and the orthographic projection of the packaging unit 210 on the first substrate 100 is annular, and the annular shape can be determined according to the morphology of the orthographic projection of the panel area 200 on the first substrate 100, for example, the inner and outer boundaries of the annular are circular or elliptical, the inner and outer boundaries of the annular are rectangular annular structures, or the inner and outer boundaries of the annular are runway-shaped, etc.; there is a fourth spacing distance between the surface of the packaging unit 210 away from the substrate and the first substrate 100, and the second spacing distance is greater than or equal to the fourth spacing distance. The support structure 310 can provide more stable support to the cover plate to improve the gap between the support structure 310 and the cover plate when the second spacing distance is less than the fourth spacing distance, which affects the supporting function of the support structure 310.

[0131] like Figures 1 to 15As shown, the embodiment of the first aspect of the present application further provides a display panel motherboard 10, the display panel motherboard 10 comprises: a first substrate 100; a plurality of panel areas 200, which are arranged on one side of the first substrate 100, and the plurality of panel areas 200 are distributed at intervals; at least one supporting assembly 300, which is arranged on one side of the first substrate 100, and the supporting assembly 300 comprises a supporting structure 310 located between two adjacent panel areas 200; wherein the display panel motherboard 10 further comprises a plurality of pixel definition layers 240, and the pixel definition layers 240 are arranged corresponding to the panel areas 200, and The orthographic projection of the pixel definition layer 240 on the first substrate 100 is located within the orthographic projection of the panel area 200 on the first substrate 200, and the pixel definition layer 240 has a first surface 241 away from the side of the first substrate 100, and the distance between the first surface 241 and the first substrate 100 is a first spacing distance; the support structure 310 has a second surface 310a away from the side of the first substrate 100, and the distance between the second surface 310a and the first substrate 100 is a second spacing distance; the absolute value of the difference between the first spacing distance and the second spacing distance is a first threshold.

[0132] In the display panel motherboard 10 provided in the embodiment of the present application, the display panel motherboard 10 includes a first substrate 100, a plurality of panel areas 200 and at least one supporting assembly 300.

The supporting assembly 300 includes a supporting structure 310, and at least one supporting structure 310 is located between two adjacent panel areas 200. When the second substrate 400 is subsequently set, the supporting structure 310 can provide support to the second substrate 400 to improve display problems such as Newton rings caused by deformation of the second substrate 400, and can improve the display effect of the display panel. There is a first spacing distance between the pixel definition layer 240 and the first substrate 100 in the panel area 200, and there is a second spacing distance between the support structure 310 and the first substrate 100. The absolute value of the difference between the first spacing distance and the second spacing distance is a first threshold, so that the difference between the first spacing distance and the second spacing distance is small. The pixel definition layer 240 and the support structure 310 can cooperate to provide good support to the second substrate 400, thereby better improving the deformation problem of the cover.
