[0003] In order to improve light extraction efficiency, the industry has developed the CFOT (Color Filter on TFT) structure in existing OLED display panels. The CFOT structure requires the setting of multiple organic film layers, which leads to a reduction in light extraction efficiency and seriously affects the display effect. Summary of the Invention

The first encapsulation layer includes a barrier setting area, and the barrier setting area does not overlap with the pixel opening along a first direction. A raised baffle structure is located on the side of the first encapsulation layer away from the substrate and in the baffle setting area. The raised baffle structure is in the form of a closed ring, and the inner sidewall of the raised baffle structure forms a receiving groove with the surface of the first encapsulation layer. A color filter layer is located on the side of the display layer away from the substrate. The color filter layer includes a color resist structure, which is disposed corresponding to the light-emitting element.

It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0013] Figure 1 This is a schematic diagram of the structure of a display panel provided in an embodiment of the present invention. Figure 2 This is a schematic diagram of another display panel structure provided in an embodiment of the present invention. Figure 3 This is a schematic diagram of another display panel structure provided in an embodiment of the present invention, such as... Figures 1-3As shown, the display panel includes: a substrate 10; a pixel defining layer 11 located on one side of the substrate 10, the pixel defining layer 11 including a plurality of pixel openings 12; a plurality of light-emitting elements 13, the light-emitting elements 13 being located within the pixel openings 12; a first encapsulation layer 14 located on the side of the pixel defining layer 11 away from the substrate 10, the first encapsulation layer 14 including a barrier setting area 15 along a first direction Z, the barrier setting area 15 not overlapping with the pixel openings 12; a raised barrier structure 16 located on the side of the first encapsulation layer 14 away from the substrate 10 and located within the barrier setting area 15, the raised barrier structure 16 being a closed ring, the inner sidewall 60 of the raised barrier structure 16 forming a receiving groove with the surface of the first encapsulation layer 14; and a color filter layer 17 located on the side of the display layer away from the substrate 10, the color filter layer 17 including a color resist structure 18, the color resist structure 18 being correspondingly disposed with the light-emitting elements 13, and the color resist structure 18 being at least partially located within the receiving groove, wherein the first direction Z is the thickness direction of the display panel.

[0014] The substrate 10 may include a substrate 19 and a driving circuit 20 located on one side of the substrate 19. The substrate 19 may be a rigid substrate or a flexible substrate, and the specific material of the substrate 19 may be selected according to actual design requirements. This embodiment of the invention does not impose specific limitations. The driving circuit 20 may be a 2T1C circuit, i.e., a circuit with two thin-film transistors and one storage capacitor, or a 7T1C circuit, i.e., a circuit with seven thin-film transistors and one storage capacitor, etc. This embodiment of the invention does not impose limitations on the specific structure of the driving circuit 20. The driving circuit 20 is electrically connected to the light-emitting element 13 and is used to provide driving signals to the light-emitting element 13, thereby ensuring normal display. The display panel also includes a pixel definition layer, which includes an open area and a non-open area. The open area includes a plurality of pixel openings 12, and the light-emitting element 13 is formed within the pixel opening 12. The pixel opening 12 defines the opening area of ​​the light-emitting element 13. The light-emitting element 13 includes a first electrode, a light-emitting layer, and a second electrode. The first electrode is electrically connected to the driving circuit 20, thereby achieving electrical connection between the light-emitting element 13 and the driving circuit 20, ensuring that the driving circuit 20 drives the light emission for display, and realizing the display function of the display panel. A first encapsulation layer 14 is also provided on the side of the light-emitting element 13 away from the substrate 10. The first encapsulation layer 14 can be prepared by chemical vapor deposition of inorganic materials such as silicon nitride and silicon oxide. The first encapsulation layer 14 plays a certain barrier role, effectively preventing the intrusion of external water and oxygen, and preventing the light-emitting layer in the light-emitting element 13 from failing. The first encapsulation layer 14 includes a barrier setting area 15. Along the first direction Z, the barrier setting area 15 does not overlap with the pixel opening 12, which can be understood as the barrier setting area 15 surrounding the pixel opening 12. The display panel also includes a raised barrier structure 16 located on the side of the first encapsulation layer 14 away from the substrate 10 and located in the barrier setting area 15. The raised barrier structure 16 can be prepared by patterning or etching processes. The raised baffle structure 16 is a closed ring. The inner sidewall 60 of the raised baffle structure 16 forms a receiving groove with the surface of the first encapsulation layer 14, and then fills the receiving groove with a color resist structure 18. The color resist structure 18 can improve the color purity of the light emitted by the light-emitting element 13 and ensure the display effect of the display panel. The color resist structure 18 can be prepared by inkjet printing process using organic color resist material. The color filter layer 17 includes color resist structures 18 of different colors. The color resist structures 18 of different colors can include red color resist structure, green color resist structure and blue color resist structure. The light-emitting element 13 includes red light-emitting element, green light-emitting element and blue light-emitting element. The red color resist structure is correspondingly set with the red light-emitting element, the green color resist structure is correspondingly set with the green light-emitting element, and the blue color resist structure is correspondingly set with the blue light-emitting element to ensure the color display effect of the display panel. The raised baffle structure 16 can be correspondingly set with the light-emitting element 13 of different colors. The raised baffle structure 16 can correspondingly support the color resist structure 18 of different colors. For example, Figure 2 and Figure 3 As shown, the raised retaining wall structure 16 can be integrally installed, or as... Figure 1 As shown, the raised barrier structures 16 can be set independently. The setting of the raised barrier structures 16 can avoid crosstalk between color resist structures 18 of different colors, ensuring the display effect of the display panel. A color filter layer 17 is formed directly on the side of the first encapsulation layer 14 away from the substrate 10, and then the second encapsulation layer 21, touch film layer 22, etc. are prepared. Compared with the prior art, this effectively reduces the number of film layers in the display panel, reduces the overall thickness of the display panel, improves the light emission efficiency of the display panel, and ensures the display effect of the display panel.

[0015] In this embodiment of the invention, a raised barrier structure is formed on the side of the first encapsulation layer away from the substrate and in the barrier setting area. The raised barrier structure is in the form of a closed ring. The inner sidewall of the raised barrier structure forms a receiving groove with the surface of the first encapsulation layer, and a color resist structure is placed in the receiving groove. This effectively reduces the film layer of the display panel, reduces the overall thickness of the display panel, improves the light emission efficiency of the display panel, and ensures the display effect of the display panel.

[0016] Optional, continue to refer to Figure 2 and Figure 3 As shown, the first encapsulation layer 14 is integrally formed with the raised retaining wall structure 16.

[0017] The raised barrier structure 16 can be formed simultaneously during the fabrication of the first encapsulation layer 14, simplifying the process and reducing costs. Furthermore, the first encapsulation layer 14 and the raised barrier structure 16 form an integrated structure, resulting in a tighter connection between them and ensuring the quality and reliability of the display panel.

[0018] Optional, continue to refer to Figure 3 As shown, the first encapsulation layer 14 also includes a groove structure 141, the projection of which is located between adjacent raised retaining wall structures 16.

[0019] Considering the fluidity of the color resist structure 18 in the inkjet printing process, a groove structure 141 can also be provided in the first encapsulation layer 14. The groove structure 141 is located between adjacent raised baffle structures 16, and the raised baffle structures 16 corresponding to each color resist structure 18 are independently set. The presence of the groove structure 141 can bear the overflow during the fabrication process of the color resist structure 18, reduce crosstalk between the color resist structures 18, and ensure the display effect of the display panel. The depth of the groove structure 141 is less than or equal to the height of the raised baffle structure 16. The depth of the groove structure 141 can be set according to actual design requirements, and this embodiment of the invention does not impose specific limitations.

[0020] Optional, continue to refer to Figure 1Along the second direction X, the width of the raised retaining wall structure 16 is w, where w > 1 μm. The second direction X is parallel to the plane where the substrate 10 is located and intersects with the first direction Z.

[0021] The width of the raised retaining wall structure 16 can be at least greater than 1μm to ensure the structural stability of the raised retaining wall structure 16, thereby ensuring its capacity to accommodate the color resist structure 18 and reducing the risk of crosstalk between the color resist structures 18.

[0022] Optional, continue to refer to Figure 1 Along the first direction Z, the height of the raised retaining wall structure 16 is h, where h > 0.5 μm.

[0023] The height of the raised baffle structure 16 can also be limited. The height of the raised baffle structure 16 is set to be greater than 0.5μm to ensure that the closed receiving groove formed by the raised baffle structure 16 has a certain side wall area, thereby ensuring its receiving effect on the color resist structure 18, so that the color resist structure 18 has a certain thickness and improves the purity of the displayed color.

[0024] Optional, continue to refer to Figures 1-3 Along the first direction Z, the upper surface of the raised retaining wall structure 16 is flush with the upper surface of the color resist structure 18.

[0025] The recessed area formed by the raised baffle structure 16 is filled with a color resist structure 18. During the manufacturing process, the upper surface of the raised baffle structure 16 is controlled to be flush with the upper surface of the color resist structure 18 to prevent the color resist structure 18 from overflowing out of the raised baffle structure 16 and reduce the risk of display crosstalk.

[0026] Optional, Figure 4 This is a schematic diagram of another display panel structure provided in an embodiment of the present invention, such as... Figure 4 As shown, along the first direction Z, the upper surface of the color resist structure 18 is higher than the upper surface of the raised barrier structure 16; the color resist structure 18 includes a first color resist portion 180, which covers at least a portion of the upper surface of the raised barrier structure 16.

[0027] In this process, the color resist structure 18 also overlaps with the upper surface of the raised barrier structure 16. Along the first direction Z, the first color resist portion 180 of the color resist structure 18 covers at least part of the upper surface of the raised barrier structure 16, ensuring that the raised barrier structure 16 can provide a certain support for the color resist structure 18, and also ensuring the surface flatness of the color resist structure 18, improving color purity, and ensuring the display effect of the display panel.

[0028] Optional, continue to refer to Figure 4 Along the second direction X, the width of the raised retaining wall structure 16 is w, and the width of the first color resist structure 181 is w1, wherein... The second direction X is parallel to the plane where the substrate 10 is located and intersects with the first direction Z.

[0029] Specifically, the width of the first color resist structure 181 is greater than or equal to one-third the width of the raised barrier structure 16 to ensure the overlap between the first color resist structure 181 and the upper surface of the raised barrier structure 16. The width of the first color resist structure 181 is less than or equal to one-half the width of the raised barrier structure 16 to prevent the first color resist structure 181 from extending beyond the upper surface of the raised barrier structure 16, reducing the risk of color resist crosstalk and ensuring the display effect of the display panel.

[0030] Optional, Figure 5 This is a schematic diagram of another display panel structure provided in an embodiment of the present invention, such as... Figure 5 As shown, the raised retaining wall structure 16 includes at least two rings of raised retaining wall substructures 160, which are concentrically nested and spaced apart.

[0031] The raised baffle structure 16 includes at least two rings of raised baffle substructures 160. These multiple rings of raised baffle substructures 160 form a multi-layered overflow prevention structure, achieving step-by-step interception of the color resist structure 18. The number of raised baffle substructures 160 can be selected according to actual design requirements, and this embodiment of the invention does not impose a specific limitation. The spacing between adjacent raised baffle substructures 160 can be the same or different, and this spacing can be selected according to actual design requirements, and this embodiment of the invention does not impose a specific limitation. For example, the raised baffle structure 16 includes two rings of raised baffle substructures 160. The two rings of raised baffle substructures 160 are concentrically nested and spaced apart, ensuring that the overflowing color resist structure 18 can be absorbed by the spacing between adjacent raised baffle substructures 160 in different directions. This avoids crosstalk between color resist structures 18 of different colors, reduces the risk of color resist crosstalk, and ensures the display effect of the display panel.

[0032] Optional, Figure 6 This is a schematic diagram of another display panel structure provided in an embodiment of the present invention, such as... Figure 6 As shown, along the second direction X, the height of at least two rings of raised retaining wall substructures 160 gradually increases. The second direction X is parallel to the plane where the substrate 10 is located and intersects with the first direction Z.

[0033] For example, when the raised barrier structure 16 includes two raised barrier substructures 160, the height of the three raised barrier substructures 160 gradually increases along the second direction X and along the central region of the color resist structure 18 toward the edge region. The overflowing color resist material can be blocked by the multiple raised barrier substructures 160, which can further reduce the risk of color resist crosstalk.

[0034] Optional, continue to refer to Figure 5 and Figure 6 At least two raised barrier substructures 160 include a first raised barrier substructure 1601 and a second raised barrier substructure 1602. Along the second direction X, the second raised barrier substructure 1602 is located on the side of the first raised barrier substructure 1601 away from the color resist structure 18. The height of the first raised barrier substructure 1601 is h1, and the height of the second raised barrier substructure 1602 is h2, where h1≤h2. The second direction X is parallel to the plane where the substrate 10 is located and intersects with the first direction Z.

[0035] Where at least two concentric raised retaining wall substructures 160 include a first raised retaining wall substructure 1601 and a second raised retaining wall substructure 1602, such as Figure 5 As shown, the height of the first raised retaining wall substructure 1601 and the height of the second raised retaining wall substructure 1602 can be the same. The first raised retaining wall substructure 1601 and the second raised retaining wall substructure 1602 can be manufactured simultaneously, reducing the manufacturing difficulty. Figure 6 As shown, the height of the first raised barrier substructure 1601 and the height of the second raised barrier substructure 1602 can be different. The height of the first raised barrier substructure 1601 is less than the height of the second raised barrier substructure 1602. The overflow color resist structure 18 can be blocked by the second raised barrier substructure 1602 with a higher height, further reducing the risk of color resist crosstalk.

[0036] Optional, Figure 7 This is a schematic diagram of another display panel structure provided in an embodiment of the present invention, such as... Figure 3 and Figure 7 As shown, the plurality of pixel openings 12 include at least a first pixel opening 121 and a second pixel opening 122, the area of ​​the first pixel opening 121 being larger than the area of ​​the second pixel opening 122; the plurality of light-emitting elements 13 include at least a first light-emitting element 131 located in the first pixel opening 121 and a second light-emitting element 132 located in the second pixel opening 122; the raised baffle structure 16 includes a first raised baffle structure 161 corresponding to the first light-emitting element 131 and a second raised baffle structure 162 corresponding to the second light-emitting element 132; along the first direction Z, the projected area of ​​the first raised baffle structure 161 is larger than the projected area of ​​the second raised baffle structure 162.

[0037] The pixel opening 12 includes a first pixel opening 121 and a second pixel opening 122. The area of ​​the first pixel opening 121 corresponding to the first light-emitting element 131 is larger than the area of ​​the second pixel opening 122 corresponding to the second light-emitting element 132. In this case, the projected area of ​​the first raised baffle structure 161 corresponding to the first light-emitting element 131 is larger than the projected area of ​​the second raised baffle structure 162 corresponding to the second light-emitting element 132. For example, when the width of the first raised baffle structure 161 is the same as the width of the second raised baffle structure 162, the diameter of the first raised baffle structure 161 is larger than the diameter of the second raised baffle structure 162. The first receiving groove formed by the first raised baffle structure 161 is used to receive the first color resist structure 181 corresponding to the first light-emitting element 131, and the second receiving groove formed by the second raised baffle structure 162 is used to receive the second color resist structure 182 corresponding to the second light-emitting element 132. By rationally setting the dimensions of the first raised baffle structure 161 and the second raised baffle structure 162, the accommodating effect of the first raised baffle structure 161 on the first color resist structure 181 and the accommodating effect of the second raised baffle structure 162 on the second color resist structure 182 can be ensured. Along the first direction Z, the projection of the first color resist structure 181 can cover the first pixel opening 121 of the first light-emitting element 131, and the projection of the second color resist structure 182 can cover the second pixel opening 122 of the second light-emitting element 132, effectively improving the color purity of the light emitted by the first light-emitting element 131 and the second light-emitting element 132, and ensuring the display effect of the display panel.

[0038] In addition, the plurality of pixel openings 12 also include a third pixel opening 123, and the area of ​​the second pixel opening 122 is larger than the area of ​​the third pixel opening 123; the plurality of light-emitting elements 13 also include a third light-emitting element 133 located in the third pixel opening 123; the raised baffle structure 16 includes a third raised baffle structure 163 corresponding to the third light-emitting element 133; along the first direction Z, the projected area of ​​the second raised baffle structure 162 is larger than the projected area of ​​the third raised baffle structure 163, and the third receiving groove formed by the third raised baffle structure 163 is used to receive the third color resist structure 183 corresponding to the third light-emitting element 133, effectively improving the color purity of the light emitted by the third light-emitting element 133.

[0039] Optional, Figure 8 This is a schematic diagram of another display panel structure provided in an embodiment of the present invention. Figure 9 This is a schematic diagram of another display panel structure provided in an embodiment of the present invention, such as... Figure 8 and Figure 9 As shown, the inner wall 60 of the raised retaining wall structure 16 is an arc-shaped curved surface or an inclined surface.

[0040] Among them, the inner wall 60 of the raised retaining wall structure 16 can be as follows: Figure 8The curved surface shown, or as Figure 9 The inclined surface shown has an inner wall 60 with a certain curvature or inclination angle, which is conducive to the flow of color resist material during the preparation process, reduces the preparation difficulty, and ensures the preparation effect of color resist structure 18.

[0041] Optional, Figure 10 This is a schematic diagram of another display panel structure provided in an embodiment of the present invention. Figure 11 This is a schematic diagram of another display panel structure provided in an embodiment of the present invention. Figure 12 This is a schematic diagram of another display panel structure provided in an embodiment of the present invention. Figure 13 This is a schematic diagram of another display panel structure provided in an embodiment of the present invention. Figure 10 , Figure 11 , Figure 12 and Figure 13 As shown, along the first direction Z, the projected shape of the raised retaining wall structure 16 is a circular ring, a rectangular ring, or an elliptical ring.

[0042] Where, along the first direction Z, such as Figure 10 As shown, when the pixel opening 12 is circular, the projected shape of the raised barrier structure 16 can be annular; as Figure 11 As shown, when the pixel opening 12 is rectangular, the projected shape of the raised retaining wall structure 16 can be a rectangular ring; as Figure 12 As shown, when the pixel opening 12 is elliptical, the projected shape of the raised retaining wall structure 16 can be an elliptical ring.

[0043] like Figure 13 As shown, when the raised barrier structure 16 includes two raised barrier substructures 160, the projected shapes of the two raised barrier substructures 160 can be the same, both being circular, rectangular, or elliptical rings; or the projected shapes of the two raised barrier substructures 160 can be different. When the projected shape of the first raised barrier substructure 160 is circular, the projected shape of the second raised barrier substructure 160 can be rectangular. Compared to both raised barrier substructures 160 being circular, the second raised barrier substructure 160 being rectangular results in a larger spacing between adjacent raised barrier substructures 160, which can accommodate more color resist material overflow, effectively suppress the risk of color resist crosstalk, and improve the display effect of the display panel.
