[0033] DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application. In addition, it should be understood that the specific embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In the present application, the orientation words such as "upper" and "lower" generally refer to the upper and lower in the actual use or working state of the device, and specifically refer to the direction of the drawing surface in the drawings; and "inner" and "outer" refer to the outline of the device.

[0035] The present application provides a display panel and a display device, which are described in detail below. It should be noted that the description order of the following embodiments is not limited as the preferred order of the embodiments.

[0036] First, the present application provides a display panel, as shown in Figures 1 to 5 The display panel 100 includes a substrate 110, the substrate 110 has opposite first and second sides 111 and 112, the first side 111 includes a plurality of side-by-side arranged light emitting areas 113, the light emitting areas 113 are correspondingly provided with light emitting sources of the display panel 100, and at the same time, a line structure is formed inside the substrate 110, the line structure is connected with the light emitting sources in the light emitting areas 113 to control the light emitting of the corresponding light emitting sources, thereby regulating the display mode of the display panel 100.

[0037] Among them, as shown in Figure 6 and Figure 7As shown, the first side 111 of the substrate 110 is formed with a first positioning structure 114, and the first positioning structure 114 is arranged in a spaced manner with the light emitting area 113. By forming the first positioning structure 114 on the first side 111 of the substrate 110, the positioning and connection of the substrate 110 and other functional film layers are facilitated, and deviation in the connection of the other functional film layers and the substrate 110 is avoided. In addition, the first positioning structure 114 is arranged in a spaced manner with the light emitting area 113, which can avoid the first positioning structure 114 from interfering with the light emitting effect of the light emitting area 113, thereby affecting the display effect of the display panel 100.

[0038] As shown, Figures 1 to 3 The display panel 100 includes a color conversion layer 120, which is arranged opposite to the first side 111 of the substrate 110. The color conversion layer 120 includes a plurality of color conversion areas 121 arranged side by side, and the color conversion areas 121 are arranged in a corresponding manner with the light emitting areas 113. The color conversion layer 120 is mainly used for color conversion of light emitted by the light emitting source in the light emitting area 113 on the substrate 110, so that the light emitted by the light emitting source is converted into a target color after passing through the corresponding color conversion area 121 on the color conversion layer 120, thereby achieving different display requirements of the display panel 100.

[0039] The color conversion layer 120 is formed with a second positioning structure 122 on the side facing the first side 111. The second positioning structure 122 is arranged in a corresponding manner with the first positioning structure 114, and the second positioning structure 122 is connected with the first positioning structure 114. By forming the second positioning structure 122 on the color conversion layer 120, when the color conversion layer 120 is laminated with the substrate 110, the second positioning structure 122 can be connected in a corresponding manner with the first positioning structure 114, so that the color conversion areas 121 correspond one by one with the light emitting areas 113, and light crosstalk caused by misalignment between the color conversion areas 121 and the light emitting areas 113 is avoided, thereby affecting the display effect of the display panel 100.

[0040] Since the color conversion areas 121 are arranged in a corresponding manner with the light emitting areas 113, the second positioning structure 122 is arranged in a corresponding manner with the first positioning structure 114, and the first positioning structure 114 is arranged in a spaced manner with the light emitting area 113, i.e. the second positioning structure 122 is also arranged in a spaced manner with the color conversion area 121, thereby avoiding the second positioning structure 122 from interfering with the light emitting effect of the light emitting area 113 and affecting the display effect of the display panel 100.

[0041] It should be noted that the light emitting region 113 corresponds to a blue light source, and the corresponding color conversion region 121 on the color conversion layer 120 can be a red conversion region, a green conversion region and a blue conversion region, so that the light emitted by the blue light source is red light, green light and blue light after passing through the color conversion layer 120, and then mixed to form different target colors to meet the different display requirements of the display panel 100.

[0042] The red conversion region corresponds to a red quantum dot coating, and the red quantum dot emits red light under the excitation of the blue light source; the green conversion region corresponds to a green quantum dot coating, and the green quantum dot emits green light under the excitation of the blue light source; and the blue conversion region can not be coated, so that the blue light source directly passes through the region to form blue light.

[0043] It should be noted that the blue conversion region can also correspond to a blue quantum dot coating, and the light emitting source can also use other color light sources, which are not limited here, as long as the light emitting source of the light emitting region 113 can form red light, green light and blue light after passing through the color conversion region 121 on the color conversion layer 120 to realize the different display requirements of the display panel 100.

[0044] The display panel 100 in the embodiment of the application includes a substrate 110 and a color conversion layer 120, the substrate 110 has opposite first and second sides 111 and 112, the first side 111 includes a plurality of side-by-side light emitting regions 113, the first side 111 is formed with a first positioning structure 114, the first positioning structure 114 is arranged apart from the light emitting region 113, the color conversion layer 120 is arranged opposite to the first side 111 of the substrate 110, the color conversion layer 120 includes a plurality of side-by-side color conversion regions 121, the color conversion region 121 is arranged corresponding to the light emitting region 113, the color conversion layer 120 is formed with a second positioning structure 122 on the side facing the first side 111, the second positioning structure 122 is arranged corresponding to the first positioning structure 114, and the second positioning structure 122 is connected with the first positioning structure 114. Through the corresponding connection of the first positioning structure 114 and the second positioning structure 122, the color conversion region 121 on the color conversion layer and the light emitting region 113 on the substrate 110 can be arranged corresponding, avoiding the color conversion region 121 and the light emitting region 113 from being dislocated to cause light crosstalk, thereby ensuring the display effect of the display panel 100.

[0045] Optionally, as Figures 1 to 3As shown, the first positioning structure 114 is protruded on the first side 111, the second positioning structure 122 is protruded on a side of the color conversion layer 120 facing the first side 111, and a side of the first positioning structure 114 facing the second positioning structure 122 is connected with a side of the second positioning structure 122 facing the first positioning structure 114. That is, both the first positioning structure 114 and the second positioning structure 122 are in a protruded manner, and the first positioning structure 114 and the second positioning structure 122 can not only play a positioning role of making the light emitting area 113 and the color conversion area 121 correspondingly arranged, but also play a supporting role on the substrate 110 and the color conversion layer 120. By designing the thickness of the first positioning structure 114 and the second positioning structure 122, the gap size between the light emitting area 113 and the corresponding color conversion area 121 can be adjusted, so as to realize the adjustment of the light emitting angle of the display panel 100.

[0046] In some embodiments, as Figure 2 As shown, a first positioning hole 1141 is formed on a side of the first positioning structure 114 facing the second positioning structure 122, and the second positioning structure 122 is inserted into the first positioning hole 1141 to connect the second positioning structure 122 with the first positioning structure 114. By providing the first positioning hole 1141 on the first positioning structure 114, the relative position of the second positioning structure 122 with the first positioning structure 114 is more stable after the second positioning structure 122 is inserted into the first positioning hole 1141, so as to avoid the relative movement between the first positioning structure 114 and the second positioning structure 122 during the manufacturing or use of the display panel 100, thereby reducing the risk of crosstalk of the light emitted by the light emitting area 113 after passing through the color conversion area 121, and further improving the display effect of the display panel 100.

[0047] In some embodiments, as

[0048] In some embodiments, as Figure 3As shown, the second positioning structure 122 is provided with a second positioning hole 1221 on the side facing the first positioning structure 114, and the first positioning structure 114 is inserted into the second positioning hole 1221 to connect the first positioning structure 114 and the second positioning structure 122. By providing the second positioning hole 1221 on the second positioning structure 122, the relative position of the first positioning structure 114 and the second positioning structure 122 is more stable after the first positioning structure 114 is inserted into the second positioning hole 1221, avoiding the relative movement between the first positioning structure 114 and the second positioning structure 122 during the manufacturing or use of the display panel 100, thereby reducing the risk of crosstalk of the light emitted by the light emitting area 113 after passing through the color conversion area 121, and improving the display effect of the display panel 100.

[0049] In the above embodiments, the first positioning structure 114 can be directly inserted into the second positioning hole 1221, i.e., the orthographic projection of the first positioning structure 114 on the first side 111 is located inside the orthographic projection of the second positioning structure 122 on the first side 111; or the first positioning structure 114 is provided with a second positioning portion on the side facing the second positioning structure 122, and the second positioning portion is inserted into the second positioning hole 1221, so that the orthographic projection of the first positioning structure 114 on the first side 111 can coincide with the orthographic projection of the second positioning structure 122 on the first side 111, thereby facilitating the corresponding arrangement of the color conversion area 121 and the light emitting area 113, and avoiding the influence of the first positioning structure 114 and the second positioning structure 122 on the light emitting effect of the light emitting area 113.

[0050] In some embodiments, the first positioning structure 114 is provided with a first positioning hole 1141 on the side facing the second positioning structure 122, and the second positioning structure 122 is provided with a first positioning portion on the side facing the first positioning structure 114; at the same time, the second positioning structure 122 is provided with a second positioning hole 1221 on the side facing the first positioning structure 114, and the first positioning structure 114 is provided with a second positioning portion on the side facing the second positioning structure 122. The first positioning portion is inserted into the first positioning hole 1141, and the second positioning portion is inserted into the second positioning hole 1221 to connect the first positioning structure 114 and the second positioning structure 122.

[0051] The above structure design makes the first positioning structure 114 and the second positioning structure 122 capable of being clamped with each other, thereby improving the stability of the relative position of the first positioning structure 114 and the second positioning structure 122, avoiding the misalignment of the light emitting area 113 and the color conversion area 121 during the manufacturing or use of the display panel 100, reducing the risk of crosstalk of the light emitted by the light emitting area 113 after passing through the color conversion area 121, and improving the display effect of the display panel 100.

[0052] Optionally, as shown in FIG. 6, the first positioning structure 114 is provided with a first positioning hole 1141 on the side facing the second positioning structure 122, and the second positioning structure 122 is provided with a first positioning portion on the side facing the first positioning structure 114.Figure 4 As shown, the first side 111 of the substrate 110 is partially recessed to form a first positioning structure 114, and a second positioning structure 122 protrudes from the side of the color conversion layer 120 facing the first side 111. The second positioning structure 122 is inserted into the first positioning structure 114 so that the second positioning structure 122 is connected to the first positioning structure 114. That is, the first positioning structure 114 is a positioning groove provided on the first side 111 of the substrate 110, and the second positioning structure 122 is a positioning part protruding from the color conversion layer 120. The positioning connection between the substrate 110 and the color conversion layer 120 is achieved through the mutual cooperation between the positioning part and the positioning groove. At the same time, it can also prevent the light-emitting area 113 and the color conversion area 121 from being misaligned during the manufacturing or use of the display panel 100, reduce the risk of crosstalk of the light emitted by the light-emitting area 113 after passing through the color conversion area 121, and thus improve the display effect of the display panel 100.

[0053] In some embodiments, such as Figure 5 As shown, the color conversion layer 120 has a recessed portion on one side facing the first side 111 to form a second positioning structure 122. The first positioning structure 114 protrudes from the first side 111 and is inserted into the second positioning structure 122 to connect the first positioning structure 114 and the second positioning structure 122. That is, the second positioning structure 122 is a positioning groove provided on the color conversion layer 120, and the first positioning structure 114 is a positioning part protruding from the first side 111 of the substrate 110. The positioning connection between the substrate 110 and the color conversion layer 120 is achieved through the mutual cooperation between the positioning part and the positioning groove. At the same time, it can also prevent the light-emitting area 113 and the color conversion area 121 from being misaligned during the manufacturing or use of the display panel 100, reduce the risk of crosstalk of the light emitted by the light-emitting area 113 after passing through the color conversion area 121, and thus improve the display effect of the display panel 100.

[0054] In other embodiments, a positioning groove and a positioning portion are simultaneously formed on the first side surface 111 of the substrate 110 to form a first positioning structure 114. A positioning groove and a positioning portion are also simultaneously formed on the side of the color conversion layer 120 facing the first side surface 111 to form a second positioning structure 122. During connection, the positioning portion in the first positioning structure 114 is inserted into the positioning groove in the second positioning structure 122, and the positioning portion in the second positioning structure 122 is inserted into the positioning groove in the first positioning structure 114. This allows the first positioning structure 114 and the second positioning structure 122 to engage with each other, which helps to improve the stability of the relative positions of the first positioning structure 114 and the second positioning structure 122. This avoids misalignment of the light-emitting area 113 and the color conversion area 121 during the manufacturing or use of the display panel 100, reduces the risk of crosstalk of the light emitted from the light-emitting area 113 after passing through the color conversion area 121, and thus improves the display effect of the display panel 100.

[0055] Optionally, the first positioning structure 114 is located between two adjacent light emitting regions 113, and the second positioning structure 122 is located between two adjacent color conversion regions 121. Since the first positioning structure 114 and the second positioning structure 122 are correspondingly arranged, by arranging the first positioning structure 114 between two adjacent light emitting regions 113 and arranging the second positioning structure 122 between two adjacent color conversion regions 121, it is helpful to ensure the relative arrangement between the light emitting region 113 and the color conversion region 121 when the first positioning structure 114 and the second positioning structure 122 are connected, and to reduce the risk of misalignment between the light emitting region 113 and the color conversion region 121 during the manufacturing process of the display panel 100.

[0056] In some embodiments, a first positioning structure 114 is arranged between any two adjacent light emitting regions 113, a second positioning structure 122 is arranged between any two adjacent color conversion regions 121, and the first positioning structure 114 and the second positioning structure 122 are connected one by one. By arranging the first positioning structure 114 between any two adjacent light emitting regions 113 and arranging the second positioning structure 122 between any two adjacent color conversion regions 121, any one light emitting region 113 and the corresponding color conversion region 121 can be positioned by the corresponding first positioning structure 114 and second positioning structure 122, thereby further reducing the risk of misalignment between the light emitting region 113 and the color conversion region 121 during the manufacturing process of the display panel 100.

[0057] It should be noted that the arrangement position and arrangement manner of the first positioning structure 114 and the second positioning structure 122 can be adjusted according to actual manufacturing and use conditions, as long as the arrangement of the first positioning structure 114 and the second positioning structure 122 can avoid misalignment between the light emitting region 113 and the color conversion region 121 during the manufacturing or use of the display panel 100, which is not specially limited here.

[0058] Optionally, the material of the first positioning structure 114 and the second positioning structure 122 in the embodiments of the present application has thermoplasticity, that is, when the first positioning structure 114 is protruded on the first side 111 of the substrate 110 and the second positioning structure 122 is protruded on the side of the color conversion layer 120 facing the first side 111 during the manufacturing process of the display panel 100, the first positioning structure 114 and the second positioning structure 122 can be melted by heating, and then integrated by cooling, thereby realizing the connection of the first positioning structure 114 and the second positioning structure 122.

[0059] When the first positioning structure 114 is provided with the first positioning hole 1141 on the side facing the second positioning structure 122, and the second positioning structure 122 is inserted into the first positioning hole 1141; or when the second positioning structure 122 is provided with the second positioning hole 1221 on the side facing the first positioning structure 114, and the first positioning structure 114 is inserted into the second positioning hole 1221; or when the first positioning structure 114 is provided with the first positioning hole 1141 on the side facing the second positioning structure 122, the second positioning structure 122 is provided with the first positioning part on the side facing the first positioning structure 114, the second positioning structure 122 is provided with the second positioning hole 1221 on the side facing the first positioning structure 114, the first positioning structure 114 is provided with the second positioning part on the side facing the second positioning structure 122, and the first positioning part is inserted into the first positioning hole 1141 and the second positioning part is inserted into the second positioning hole 1221, since the first positioning structure 114 and the second positioning structure 122 are connected in a clamping manner, the fusion of the first positioning structure 114 and the second positioning structure 122 is more beneficial when the first positioning structure 114 and the second positioning structure 122 are heated, thereby improving the stability of the relative position of the first positioning structure 114 and the second positioning structure 122.

[0060] Optionally, the material of the first positioning structure 114 and the second positioning structure 122 in the embodiment of the application includes a magnetic material, and the side of the first positioning structure 114 facing the second positioning structure 122 is adsorbed together with the side of the second positioning structure 122 facing the first positioning structure 114. That is, the material of the first positioning structure 114 and the second positioning structure 122 is a magnetic material, and when the color conversion layer 120 is connected to the substrate 110, the connection of the first positioning structure 114 and the second positioning structure 122 can be realized through the mutual attraction between the first positioning structure 114 and the second positioning structure 122. This arrangement makes the connection between the first positioning structure 114 and the second positioning structure 122 more flexible and convenient, which helps to simplify the process procedure of the display panel 100.

[0061] The material of the first positioning structure 114 and the second positioning structure 122 can be a permanent magnet or other material with magnetism, and the specific material type can be selected according to design requirements, which is not specially limited here, as long as the effective adsorption of the first positioning structure 114 and the second positioning structure 122 is ensured.

[0062] Optionally, the material of the first positioning structure 114 and the second positioning structure 122 in the embodiments of the present application includes a light shielding material, that is, the first positioning structure 114 and the second positioning structure 122 can shield the light emitted by the light emitting sources in the two adjacent light emitting areas 113 while positioning the positions of the light emitting area 113 and the corresponding color conversion area 121, so as to further prevent the light crosstalk between the two adjacent light emitting areas 113, thereby improving the display effect of the display panel 100.

[0063] The first positioning structure 114 surrounds the light emitting area 113, and the second positioning structure 122 surrounds the color conversion area 121, that is, the first positioning structure 114 shields between any two adjacent light emitting areas 113, the second positioning structure 122 shields between any two adjacent color conversion areas 121, and the first positioning structure 114 is connected with the second positioning structure 122, so as to shield the two adjacent light emitting areas 113, avoid the light crosstalk between the light emitting sources in the two adjacent light emitting areas 113, and further improve the display effect of the display panel 100.

[0064] It should be noted that, in addition to the heating and melting and then cooling and fusing mode and the magnetic adsorption mode, the first positioning structure 114 and the second positioning structure 122 in the embodiments of the present application can also directly coat a bonding layer on the side of the first positioning structure 114 facing the second positioning structure 122 and the side of the second positioning structure 122 facing the first positioning structure 114, and realize the connection of the first positioning structure 114 and the second positioning structure 122 through the bonding effect between the bonding layers.

[0065] In addition, the first positioning structure 114 and the second positioning structure 122 can also be directly connected by vacuum adsorption. The specific connection mode of the first positioning structure 114 and the second positioning structure 122 can be selected according to actual design requirements, which is not specially limited here, as long as the first positioning structure 114 and the second positioning structure 122 can be effectively connected to avoid misalignment of the light emitting area 113 and the corresponding color conversion area 121 during the manufacturing or use of the display panel 100.
