DETAILED DESCRIPTION

[0045] In order to enable those skilled in the art to understand the present application more clearly, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of this application.

[0046] Figure 1 For a schematic diagram of the structure of a display panel in the related art, please refer to Figure 1 The display panel includes a base substrate 10', a pixel definition layer 21', a red light emitting structure 22', a blue light emitting structure 23', a green light emitting structure 24', a first passivation layer 31', a flat layer 32', a second passivation layer 33', a buffer layer 34', a first touch metal layer 41', a touch insulating layer 42', a second touch metal layer 43', a first protective layer 50', a red film layer 61', a blue film layer 62', a green film layer 63' and a second protective layer 70'.

[0047] A driving circuit is provided on one side of the base substrate 10'. A pixel definition layer 21' is located on the side of the base substrate 10' where the driving circuit is provided. The pixel definition layer 21' has a plurality of openings 210' spaced apart from each other. A light-emitting structure is located within the opening 210' and is connected to the driving circuit. The light-emitting structure within one opening 210' can emit light of one color when driven by the driving circuit. The light-emitting structures within the plurality of openings 210' include a light-emitting structure that emits red light (i.e., a red light-emitting structure 22'), a light-emitting structure that emits blue light (i.e., a blue light-emitting structure 23'), and a light-emitting structure that emits green light (i.e., a green light-emitting structure 24').

[0048] The first passivation layer 31', planarization layer 32', second passivation layer 33', buffer layer 34', touch insulation layer 42', and first protective layer 50' are sequentially stacked on the pixel definition layer 21', covering the pixel definition layer 21', the red light-emitting structure 22', the blue light-emitting structure 23', and the green light-emitting structure 24'. The touch insulation layer 42' has a plurality of interconnecting holes 420' spaced apart from each other. The first touch metal layer 41' is located between the touch insulation layer 42' and the first protective layer 50'. The second touch metal layer 43' is located between the touch insulation layer 42' and the buffer layer 34' and extends into the interconnecting holes 420' to connect with the first touch metal layer 41'.

[0049] The red film layer 61', the blue film layer 62', and the green film layer 63' are sequentially stacked on the first protective layer 50'. The orthographic projection of the red film layer 61' on the base substrate 10' covers the orthographic projection of the pixel definition layer 21' and the red light emitting structure 22' on the base substrate 10'. The orthographic projection of the blue film layer 62' on the base substrate 10' covers the orthographic projection of the pixel definition layer 21' and the blue light emitting structure 23' on the base substrate 10'. The orthographic projection of the green film layer 63' on the base substrate 10' covers the orthographic projection of the pixel definition layer 21' and the green light emitting structure 24' on the base substrate 10'. The red film layer 61', the blue film layer 62', and the green film layer 63' are stacked directly above the pixel definition layer 21', which can replace the black matrix. Therefore, there is no need to set up a black matrix separately, which saves the black matrix formation process, reduces the process complexity and production cost, and can also improve the hue. However, in order to stack the red film layer 61', the blue film layer 62', and the green film layer 63' directly above the pixel definition layer 21', the thickness of the blue film layer 62' directly above the blue light emitting structure 23' needs to be greater than the thickness of the red film layer 61', and the thickness of the green film layer 63' directly above the green light emitting structure 24' needs to be greater than the sum of the thicknesses of the red film layer 61' and the blue film layer 62', resulting in the green film layer 63' being too thick (generally 2μm to 3μm thick), reducing the transmittance of light and affecting the light output efficiency of the product.

[0050] Figure 2 For a schematic diagram of the structure of the display panel in one or more embodiments of the present application, please refer to Figure 2 In a first embodiment of the present application, a display panel is provided, which includes a base substrate 10, multiple light-emitting structures, an encapsulation layer 27, an insulating layer 21, a first color filter layer 31, a second color filter layer 32 and a third color filter layer 33.

[0051] The base substrate 10 has a first light-emitting area 11, a second light-emitting area 12, a third light-emitting area 13, and a light-shielding area 14. The multiple light-emitting structures include a first light-emitting structure 261 located in the first light-emitting area 11, a second light-emitting structure 262 located in the second light-emitting area 12, and a third light-emitting structure 263 located in the third light-emitting area 13. The light-shielding area 14 is located between adjacent light-emitting structures. An encapsulation layer 27 covers the light-emitting structures and the light-shielding area 14. An insulating layer 21 is located on the side of the encapsulation layer 27 facing away from the base substrate 10. A boss 210 is formed on the side of the insulating layer 21 facing away from the base substrate 10. The orthographic projection of the boss 210 on the base substrate 10 is located in the third light-emitting area 13.

[0052] The first color filter layer 31 is located on the side of the insulating layer 21 away from the substrate 10. The orthographic projection of the first color filter layer 31 on the substrate 10 is located in the first light-emitting area 11 and the light-shielding area 14. The second color filter layer 32 is located on the side of the insulating layer 21 away from the substrate 10 and on the side of the first color filter layer 31 away from the substrate 10. The orthographic projection of the second color filter layer 32 on the substrate 10 is located in the second light-emitting area 12 and the light-shielding area 14. The third color filter layer 33 is located on the boss 210 and on the side of the second color filter layer 32 away from the substrate 10. The orthographic projection of the third color filter layer 33 on the substrate 10 is located in the third light-emitting area 13 and at least part of the light-shielding area 14. The plane of the surface of the first color filter layer 31 closest to the substrate 10 is located between the surface of the third color filter layer 33 closest to the substrate 10 and the substrate 10. In the light-shielding area 14, the orthographic projection of the first color filter layer 31 on the substrate 10 overlaps with the orthographic projection of the third color filter layer 33 on the substrate 10.

[0053] For example, the light-emitting structures in the first, second, and third light-emitting zones 11, 12, and 13 can emit light of different colors. That is, the first, second, and third light-emitting zones 11, 12, and 13 are light-emitting zones of different colors. For example, if the light-emitting structures in the first light-emitting zone 11 emit red light, the first light-emitting zone 11 is a red light-emitting zone. If the light-emitting structures in the second light-emitting zone 11 emit blue light, the second light-emitting zone 12 is a blue light-emitting zone. If the light-emitting structures in the third light-emitting zone 13 emit green light, the third light-emitting zone 13 is a green light-emitting zone.

[0054] The first, second, and third color filter layers 31, 32, and 33 are different colored layers. The colors of the color filter layers correspond to the colors of the light-emitting zones in which they are located. For example, if the first light-emitting zone 11 is red, the first color filter layer 31 is a red layer. If the second light-emitting zone 12 is blue, the second color filter layer 32 is a blue layer. If the third light-emitting zone 13 is green, the third color filter layer 33 is a green layer.

[0055] See also Figure 2The orthographic projection of the second color filter layer 32 located on the insulating layer 21 on the base substrate 10 is located in the second light-emitting area 12. The orthographic projection of the second color filter layer 32 located on the first color filter layer 31 on the base substrate 10 is located in the light-shielding area 14. The orthographic projection of the third color filter layer 33 located on the insulating layer 21 on the base substrate 10 is located in the third light-emitting area 13. The orthographic projection of the third color filter layer 33 located on the second color filter layer 32 on the base substrate 10 is located in the light-shielding area 14. The first color filter layer 31, the second color filter layer 32, and the third color filter layer 33 can be superimposed in the light-shielding area 14 to form a black matrix.

[0056] Compared with setting up a black matrix alone, the reflectivity of the superimposed color film is better, as shown in Table 1 below.

[0057] Table 1 Comparison of reflectivity of black matrix and superimposed color film

[0058]

[0059] The display panel includes a base substrate 10, multiple light-emitting structures, an encapsulation layer 27, an insulating layer 21, a first color filter layer 31, a second color filter layer 32, and a third color filter layer 33. The multiple light-emitting structures, encapsulation layer 27, insulating layer 21, first color filter layer 31, second color filter layer 32, and third color filter layer 33 are sequentially stacked on the base substrate 10. The first color filter layer 31 is located in the first light-emitting area 11 and the light-shielding area 14, the second color filter layer 32 is located in the second light-emitting area 12 and the light-shielding area 14, and the third color filter layer 33 is located in the third light-emitting area 13 and the light-shielding area 14. By stacking the first, second, and third color filter layers 31, 32, and 33 in the light-shielding area to form a black matrix, a separate imaging and development process is not required to form the black matrix, thereby reducing one imaging and development process, reducing process complexity and manufacturing cost. In addition, the insulating layer 21 has a boss 210 on the side away from the base substrate 10. The orthographic projection of the boss 210 on the base substrate 10 is located on the insulating layer 21 in the third light-emitting area 13. The boss 210 raises the third color filter layer 33 of the third light-emitting area 13, so that the setting surface of the third color filter layer 33 in the third light-emitting area 13 is higher than the setting surface of the first color filter layer 31 in the first light-emitting area 11. The thickness of the third color filter layer 33 in the third light-emitting area 13 does not need to be greater than the thickness of the first color filter layer 31 and the second color filter layer 32. After that, the third color filter layer 33 in the light-shielding area 14 can also be superimposed on the first color filter layer 31 and the second color filter layer 32, which is conducive to reducing the thickness of the third color filter layer 33 and improving the light extraction efficiency of the product.

[0060] In some embodiments, see Figure 2The first light-emitting area 11, the second light-emitting area 12, and the third light-emitting area 13 are spaced apart from each other, and the light-shielding area 14 can surround the first light-emitting area 11, the second light-emitting area 12, and the third light-emitting area 13. That is, the edges of the first light-emitting area 11, the edges of the second light-emitting area 12, and the edges of the third light-emitting area 13 are all surrounded by the light-shielding area 14, and the light-shielding areas 14 surrounding two adjacent light-emitting areas are connected together, so as to reserve space between the two adjacent light-emitting areas for setting the black matrix.

[0061] For example, see Figure 2 The third light-emitting area 13 can be located between the first light-emitting area 11 and the second light-emitting area 12. In this way, the third color filter layer 33 finally stacked is located between the first color filter layer 31 and the second color filter layer 32, and the overall stability of the structure is better.

[0062] In other embodiments, the second light-emitting area 12 may be located between the first light-emitting area 11 and the third light-emitting area 13 , and the first light-emitting area 11 may be located between the second light-emitting area 12 and the third light-emitting area 13 .

[0063] Illustratively, in the direction perpendicular to the base substrate 10 , the sum of the thicknesses of the first color filter layer 31 , the second color filter layer 32 and the third color filter layer 33 may be 1 μm to 6 μm, such as 1 μm, 2 μm, 3 μm, 4 μm, 5 μm, 6 μm, etc.

[0064] Figure 3 For a structural diagram of a display panel in another embodiment of the present application, please refer to Figure 3 In some embodiments, the plane of the surface of the second color filter layer 32 closest to the base substrate 10 can be located between the surface of the third color filter layer 33 closest to the base substrate 10 and the base substrate 10. Furthermore, in the light-shielding area 14, the orthographic projection of the second color filter layer 32 on the base substrate 10 overlaps with the orthographic projection of the third color filter layer 33 on the base substrate 10. In this case, the surface of the third color filter layer 33 in the third light-emitting area 13 is not only higher than the surface of the first color filter layer 31 in the first light-emitting area 11, but also higher than the surface of the second color filter layer 32 in the second light-emitting area 12. This facilitates further reducing the thickness of the third color filter layer 33 and improving the light extraction efficiency of the product.

[0065] In some embodiments, see Figure 2 and Figure 3 The first color filter layer 31 is disposed on the portion of the insulating layer 21 without the protrusions 210 (i.e., the insulating layer 21 in the first light-emitting area 11 and the light-shielding area 14). The second color filter layer 32 is disposed on the portion of the insulating layer 21 without the protrusions 210 (i.e., the insulating layer 21 in the second light-emitting area 12) and on the first color filter layer 31 in the light-shielding area 14. The third color filter layer 33 is disposed on the protrusions 210 and the second color filter layer 32 in the light-shielding area 14.

[0066] In the above embodiment, by providing a boss 210 on the side of the insulating layer 21 away from the base substrate 10, the boss 210 is located in the third light-emitting area 13, so that the setting surface of the third color filter layer 33 of the third light-emitting area 13 can be raised, so that the setting surface of the third color filter layer 33 of the third light-emitting area 13 is higher than the setting surface of the first color filter layer 31 and the setting surface of the second color filter layer 32 of the second light-emitting area 12, and even higher than the setting surface of the second color filter layer 32 of the shading area 14, which is conducive to reducing the thickness of the third color filter layer 33 and improving the light extraction efficiency of the product.

[0067] In other embodiments, the insulating layer 21 may also have a groove on the side away from the base substrate 10. The orthographic projection of the groove on the base substrate 10 is located in the first light-emitting area 11, the second light-emitting area 12, and the light-shielding area 14. The first color filter layer 31 and the second color filter layer 32 are disposed within the groove, while the third color filter layer 33 located in the third light-emitting area 13 is disposed outside the groove. The second color filter layer 32 located in the light-shielding area 14 is disposed on the first color filter layer 31, and the third color filter layer 33 located in the light-shielding area 14 is disposed on the second color filter layer 32.

[0068] For example, see Figure 3 In the direction perpendicular to the base substrate 10, the height of the boss 210 can be greater than the thickness of the first color filter layer 31. In this case, the plane where the surface of the second color filter layer 32 closest to the base substrate 10 is located is located between the surface of the third color filter layer 33 closest to the base substrate 10 and the base substrate 10, which is conducive to further reducing the thickness of the third color filter layer 33 and improving the light extraction efficiency of the product.

[0069] In other embodiments, in a direction perpendicular to the base substrate 10 , the height of the boss 210 may be smaller than the thickness of the first color filter layer 31 , or may be equal to the thickness of the first color filter layer 31 .

[0070] For example, see Figure 3 In a direction perpendicular to the base substrate 10, the height of the boss 210 can be equal to the sum of the thicknesses of the first color filter layer 31 and the second color filter layer 32. In this case, the surface of the boss 210 on which the third color filter layer 33 is disposed is coplanar with the surface of the second color filter layer 32 on which the third color filter layer 33 is disposed. The third color filter layer 33 can be laid flat on the boss 210 and the second color filter layer 32.

[0071] In other embodiments, in the direction perpendicular to the base substrate 10 , the height of the boss 210 may be less than the sum of the thicknesses of the first color filter layer 31 and the second color filter layer 32 , or may be greater than the sum of the thicknesses of the first color filter layer 31 and the second color filter layer 32 .

[0072] Figure 4 This is a structural diagram of a display panel in another embodiment of the present application. Figure 4 In one possible embodiment, the insulating layer 21 may be a first protective layer 22. The first protective layer 22 has a first high region 221 and a first low region 222. In a direction perpendicular to the base substrate 10, the thickness of the first protective layer 22 in the first high region 221 is greater than the thickness in the first low region 222.

[0073] The first low region 222 covers the first luminous region 11, the second luminous region 12, and the light-shielding region 14. The first high region 221 is located in the third luminous region 13. The first color filter layer 31 is disposed on the first protective layer 22 in the first low region 222. The second color filter layer 32 is disposed on the first protective layer 22 in the first low region 222 and the first color filter layer 31 in the light-shielding region 14. The third color filter layer 33 is disposed on the first protective layer 22 in the first high region 221 and the second color filter layer 32 in the light-shielding region 14.

[0074] In the above embodiment, the first protective layer 22 has a first high region 221 and a first low region 222 of different thicknesses. This difference in thickness between the first high region 221 and the first low region 222 allows for the formation of a boss 210 on the side of the insulating layer 21 away from the base substrate 10. The thicker first high region 221 is located in the third light-emitting region 13, while the thinner first low region 222 is located in the first light-emitting region 11, the second light-emitting region 12, and the light-shielding region 14. This ensures that the surface of the third color filter layer 33 in the third light-emitting region 13 is higher than the surface of the first color filter layer 31, the surface of the second color filter layer 32 in the second light-emitting region 12, and even higher than the surface of the second color filter layer 32 in the light-shielding region 14. This facilitates reducing the thickness of the third color filter layer 33 and improving the light extraction efficiency of the product.

[0075] For example, the first protection layer 22 may be formed of a transparent material.

[0076] Illustratively, in a direction perpendicular to the base substrate 10 , the thickness of the first protective layer 22 may be 1 μm to 6 μm, such as 1 μm, 1.5 μm, 2 μm, 2.5 μm, 3 μm, 3.5 μm, 4 μm, 4.5 μm, 5 μm, 5.5 μm, 6 μm, etc.

[0077] For example, see Figure 4 The display panel may further include a touch insulating layer 23 , a first touch metal layer 241 , and a second touch metal layer 242 . The touch insulating layer 23 is located between the first protection layer 22 and the encapsulation layer 27 . Figure 5 This is a top view of the first touch metal layer of the present application. Figure 5The touch insulation layer 23 has a connecting hole 230. The first touch metal layer 241 is located between the touch insulation layer 23 and the first protective layer 10. The first touch metal layer 241 includes a plurality of first touch sub-electrodes 91 arranged sequentially and spaced apart from each other along the first direction, and a plurality of second touch sub-electrodes 92 and a plurality of connecting electrodes 93 arranged sequentially along the second direction. The plurality of second touch sub-electrodes 92 and the plurality of connecting electrodes 93 are alternately arranged and sequentially connected to form a second touch electrode extending along the second direction. The first direction intersects the second direction, and the first touch sub-electrodes 91 and the second touch sub-electrodes 92 are spaced apart from each other. The second touch metal layer 242 is located between the touch insulation layer 23 and the encapsulation layer 27. The second touch metal layer 242 includes a plurality of bridging electrodes spaced apart from each other. A bridging electrode connects two adjacent first touch sub-electrodes through the connecting hole 230 to form a first touch electrode extending along the first direction.

[0078] For example, see Figure 4 The orthographic projection of the connecting hole 230 on the base substrate 10, the orthographic projection of the first touch metal layer 241 on the base substrate 10, and the orthographic projection of the second touch metal layer 242 on the base substrate 10 can all be located in the light shielding area 14. In this way, the black matrix can be used to shield the first touch metal layer 241 and the second touch metal layer 242, thereby avoiding affecting the display effect of the product.

[0079] Exemplarily, the touch insulating layer 23 may be formed of a transparent material.

[0080] Figure 6 This is a structural diagram of a display panel in another embodiment of the present application. Figure 6 In another possible embodiment, the insulating layer 21 may include a first protective layer 22 and a touch insulating layer 23. The touch insulating layer 23 is located on a side of the encapsulation layer 27 away from the base substrate 10. The first protective layer 22 is located on a side of the touch insulating layer 23 away from the base substrate 10.

[0081] The orthographic projection of the touch insulation layer 23 on the base substrate 10 covers the first light-emitting area 11, the second light-emitting area 12, the third light-emitting area 13, and the light-shielding area 14. The orthographic projection of the first protective layer 22 on the base substrate 10 is located in the third light-emitting area 13. The first color filter layer 31 is provided on the touch insulation layer 23, the second color filter layer 32 is provided on the touch insulation layer 23 and the first color filter layer 31 located in the light-shielding area 14, and the third color filter layer 33 is provided on the first protective layer 22 and the second color filter layer 32 located in the light-shielding area 14.

[0082] In the above embodiment, a touch insulating layer 23 and a first protective layer 22 are sequentially provided on the side of the encapsulation layer 27 away from the base substrate 10. The first protective layer 22 only partially covers the touch insulating layer 23. The thickness difference created by whether the first protective layer 22 is provided on the touch insulating layer 23 forms a boss 210 on the side of the insulating layer 21 away from the base substrate 10. The first protective layer 22 is located in the third luminescent region 13, while the portion of the touch insulating layer 23 not covered by the first protective layer 22 is located in the first luminescent region 11, the second luminescent region 12, and the light-shielding region 14. This ensures that the surface of the third color filter layer 33 in the third luminescent region 13 is higher than the surface of the first color filter layer 31, the surface of the second color filter layer 32 in the second luminescent region 12, and even higher than the surface of the second color filter layer 32 in the light-shielding region 14. This helps reduce the thickness of the third color filter layer 33 and improves the light extraction efficiency of the product.

[0083] Exemplarily, the first protection layer 22 and the touch insulating layer 23 may be formed of a transparent material.

[0084] Illustratively, in a direction perpendicular to the base substrate 10 , the thickness of the first protective layer 22 may be 1 μm to 6 μm, such as 1 μm, 1.5 μm, 2 μm, 2.5 μm, 3 μm, 3.5 μm, 4 μm, 4.5 μm, 5 μm, 5.5 μm, 6 μm, etc.

[0085] In some embodiments, see Figure 6 , the touch insulating layer 23 has a connecting hole 230 .

[0086] The display panel may also include a first touch metal layer 241 and a second touch metal layer 242. The first touch metal layer 241 is located between the touch insulation layer 23 and the first color filter layer 31. The first touch metal layer 241 includes a plurality of first touch sub-electrodes arranged sequentially and spaced apart from each other along a first direction, and a plurality of second touch sub-electrodes and a plurality of connecting electrodes arranged sequentially along a second direction. The plurality of second touch sub-electrodes and the plurality of connecting electrodes are alternately arranged and sequentially connected to form second touch electrodes extending along the second direction. The first direction intersects the second direction, and the first touch sub-electrodes and the second touch sub-electrodes are spaced apart from each other. The second touch metal layer 242 is located between the touch insulation layer 23 and the encapsulation layer 27. The second touch metal layer 242 includes a plurality of bridging electrodes spaced apart from each other. Each bridging electrode is connected to two adjacent first touch sub-electrodes via a connecting hole 230, forming a first touch electrode extending along the first direction.

[0087] For example, see Figure 6The orthographic projection of the connecting hole 230 on the base substrate 10, the orthographic projection of the first touch metal layer 241 on the base substrate 10, and the orthographic projection of the second touch metal layer 242 on the base substrate 10 can all be located in the light shielding area 14. In this way, the black matrix can be used to shield the first touch metal layer 241 and the second touch metal layer 242, thereby avoiding affecting the display effect of the product.

[0088] Figure 7 This is a structural diagram of a display panel in another embodiment of the present application. Figure 7 In another possible embodiment, the insulating layer 21 may be a touch insulating layer 23. The touch insulating layer 23 is formed of an organic encapsulation material and has a second high region 231 and a second low region 232. In a direction perpendicular to the base substrate 10, the thickness of the touch insulating layer 23 in the second high region 231 is greater than the thickness in the second low region 232.

[0089] The second lower region 232 covers the first luminous region 11, the second luminous region 12, and the light-shielding region 14. The second upper region 231 is located in the third luminous region 13. The first color filter layer 31 is disposed on the touch insulation layer 23 in the second lower region 232. The second color filter layer 32 is disposed on the touch insulation layer 23 in the second lower region 232 and the first color filter layer 31 in the light-shielding region 14. The third color filter layer 33 is disposed on the touch insulation layer 23 in the second upper region 231 and the second color filter layer 32 in the light-shielding region 14.

[0090] In the above embodiment, the touch insulating layer 23 is formed of an organic encapsulating material, which can replace the protective layer to achieve display panel encapsulation. This eliminates the need for a separate first protective layer, thus simplifying the first protective layer formation process and reducing process complexity and manufacturing costs. Furthermore, different regions of the touch insulating layer 23 can have different thicknesses. By having the touch insulating layer 23 have a second high region 231 and a second low region 232 of varying thicknesses, the thickness difference between the second high region 231 and the second low region 232 can be utilized to form a boss 210 on the side of the insulating layer 21 away from the substrate 10. The thicker second high region 231 is located in the third luminescent region 13, while the thinner second low region 232 is located in the first luminescent region 11, the second luminescent region 12, and the light-shielding region 14. This allows the surface of the third color filter layer 33 in the third luminescent region 13 to be higher than the surface of the first color filter layer 31, the surface of the second color filter layer 32 in the second luminescent region 12, and even higher than the surface of the second color filter layer 32 in the light-shielding region 14. This helps reduce the thickness of the third color filter layer 33 and improves the light extraction efficiency of the product.

[0091] For example, organic packaging materials refer to packaging materials made of polymer materials containing a carbon skeleton, including organic films, organic resins, organic silicon, organic glass, etc. Organic packaging materials mainly include polymer materials such as epoxy resin, EVA (Ethylene Vinyl Acetate Copolymer), PVB (Polyvinyl Butyral), polyolefins, silicone, and TPD (Thermoplastic Polyurethane), which can play a role in bonding, protection, and insulation during the packaging process.

[0092] Exemplarily, the touch insulating layer 23 may be formed of a transparent material.

[0093] Illustratively, in a direction perpendicular to the base substrate 10 , the touch insulating layer 23 may have a thickness of 0.5 μm to 5 μm, such as 0.5 μm, 1 μm, 1.5 μm, 2 μm, 2.5 μm, 3 μm, 3.5 μm, 4 μm, 4.5 μm, 5 μm, etc.

[0094] In some embodiments, see Figure 7 , the touch insulating layer 23 has a connecting hole 230 .

[0095] The display panel may also include a first touch metal layer 241 and a second touch metal layer 242. The first touch metal layer 241 is located between the touch insulation layer 23 and the first color filter layer 31. The first touch metal layer 241 includes a plurality of first touch sub-electrodes arranged sequentially and spaced apart from each other along a first direction, and a plurality of second touch sub-electrodes and a plurality of connecting electrodes arranged sequentially along a second direction. The plurality of second touch sub-electrodes and the plurality of connecting electrodes are alternately arranged and sequentially connected to form second touch electrodes extending along the second direction. The first direction intersects the second direction, and the first touch sub-electrodes and the second touch sub-electrodes are spaced apart from each other. The second touch metal layer 242 is located between the touch insulation layer 23 and the encapsulation layer 27. The second touch metal layer 242 includes a plurality of bridging electrodes spaced apart from each other. Each bridging electrode is connected to two adjacent first touch sub-electrodes via a connecting hole 230, forming a first touch electrode extending along the first direction.

[0096] For example, see Figure 7 The orthographic projection of the connecting hole 230 on the base substrate 10, the orthographic projection of the first touch metal layer 241 on the base substrate 10, and the orthographic projection of the second touch metal layer 242 on the base substrate 10 can all be located in the light shielding area 14. In this way, the black matrix can be used to shield the first touch metal layer 241 and the second touch metal layer 242, thereby avoiding affecting the display effect of the product.

[0097] Illustratively, in a direction parallel to the base substrate 10 , the critical dimension of the connecting hole 230 can be 2 μm to 8 μm, such as 2 μm, 2.5 μm, 3 μm, 3.5 μm, 4 μm, 4.5 μm, 5 μm, 5.5 μm, 6 μm, 6.5 μm, 7 μm, 7.5 μm, 8 μm, etc.

[0098] In some embodiments, see Figure 4 、 Figure 6 and Figure 7 The display panel may further include a pixel definition layer 25, which is located between the encapsulation layer 27 and the base substrate 10. The pixel definition layer 25 has a first opening 251, a second opening 252, and a third opening 253. The first opening 251 is located in the first light-emitting region 11, and the first light-emitting structure 261 is disposed within the first opening 251. The second opening 252 is located in the second light-emitting region 12, and the second light-emitting structure 262 is disposed within the second opening 252. The third opening 253 is located in the third light-emitting region 13, and the third light-emitting structure 263 is disposed within the third opening 253.

[0099] For example, the first light emitting structure 261, the second light emitting structure 262, and the third light emitting structure 263 may emit light of different colors. For example, the first light emitting structure 261 emits red light, the second light emitting structure 262 emits blue light, and the third light emitting structure 263 emits green light.

[0100] In some embodiments, a driving circuit may be provided on one side of the base substrate 10, and the multiple light-emitting structures, the encapsulation layer 27, and the insulating layer 21 are all located on the side of the base substrate 10 where the driving circuit is provided. The first opening 251, the second opening 252, and the third opening 253 extend to the driving circuit, respectively, and the first light-emitting structure 261, the second light-emitting structure 262, and the third light-emitting structure 263 are respectively connected to the driving circuit.

[0101] In some embodiments, see Figure 4 、 Figure 6 and Figure 7 The encapsulation layer 27 may include a first passivation layer 271, a planarization layer 272, and a second passivation layer 273. The first passivation layer 271 is located between the pixel definition layer 25 and the touch insulation layer 23, and covers the pixel definition layer 25, the first light-emitting structure 261, the second light-emitting structure 262, and the third light-emitting structure 263. The planarization layer 272 is located between the first passivation layer 271 and the touch insulation layer 23. The second passivation layer 273 is located between the planarization layer 272 and the touch insulation layer 23. The second touch metal layer 242 is located between the second passivation layer 273 and the touch insulation layer 23.

[0102] In the above embodiment, the flattening layer 272 can fill the height difference between the first opening 251, the second opening 252, and the third opening 253. The first passivation layer 271 and the second passivation layer 273 are respectively provided on both sides of the flattening layer 272 to insulate the flattening layer 272.

[0103] In some embodiments, see Figure 4 、 Figure 6 and Figure 7 The display panel may further include a buffer layer 274. The buffer layer 274 is located between the second passivation layer 273 and the touch insulating layer 23. The second touch metal layer 242 is located between the buffer layer 274 and the touch insulating layer 23. Forming the buffer layer 274 on the second passivation layer 273 first and then forming the touch insulating layer 23 on the buffer layer 274 facilitates the formation of the touch insulating layer 23.

[0104] In some embodiments, see Figure 4 、 Figure 6 and Figure 7 The display panel may further include a second protective layer 28. The second protective layer 28 is located on a side of the third color filter layer 33 away from the base substrate 10 and covers the first color filter layer 31, the second color filter layer 32, and the third color filter layer 33 to encapsulate the first color filter layer 31, the second color filter layer 32, and the third color filter layer 33.

[0105] Illustratively, in a direction perpendicular to the base substrate 10 , the thickness of the second protective layer 28 may be 1 μm to 5 μm, such as 1 μm, 1.5 μm, 2 μm, 2.5 μm, 3 μm, 3.5 μm, 4 μm, 4.5 μm, 5 μm, etc.

[0106] In some embodiments, the refractive index of the first color filter layer 31 is smaller than that of the second color filter layer 32 , and the refractive index of the second color filter layer 32 is smaller than that of the third color filter layer 33 .

[0107] In the above embodiment, the first color filter layer 31, the second color filter layer 32 and the third color filter layer 33 are stacked on the insulating layer 21 in sequence, and the refractive index of the first color filter layer 31, the second color filter layer 32 and the third color filter layer 33 increases layer by layer, which is conducive to the emission of light and improves the light extraction efficiency of the product. Therefore, they can replace the low refractive index film layer and / or the high refractive index film layer, save the formation process of the low refractive index film layer and / or the high refractive index film layer, and reduce the process complexity and production cost.

[0108] For example, the first color filter layer 31, the second color filter layer 32, and the third color filter layer 33 may be made of nanofilms. Compared with non-nanofilms, nanofilms have improved brightness attenuation and color shift, as shown in Table 2 below.

[0109] Table 2 Comparison of product performance between ordinary membrane and nano membrane

[0110]

[0111] In practical applications, the refractive indices of the first color filter layer 31 , the second color filter layer 32 , and the third color filter layer 33 can be made to show a gradient change by increasing or decreasing the amount of nanoparticles in at least one of the first color filter layer 31 , the second color filter layer 32 , and the third color filter layer 33 .

Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature.
