[0048] Although the terms first, second, third, etc. can be used in the text to describe multiple elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms can only be used to distinguish an element, component, region, layer or section from another region, layer or section. Unless the context clearly indicates otherwise, terms such as "first", "second" and other numerical terms do not imply order or sequence when used in the text.

[0050] like Figures 1 to 4As shown, according to an embodiment of the present application, a display panel 1 is proposed, including a substrate 11 , a plurality of sub-pixels 12 , a first dimming layer 13 and a second dimming layer 14 . A plurality of sub-pixels 12 are formed on one side of a substrate 11, and the plurality of sub-pixels 12 include a first type of sub-pixel 121 and a second type of sub-pixel 122. A surface of the first type of sub-pixel 121 close to the substrate 11 forms a first acute angle a1 with the substrate 11, and a surface of the second type of sub-pixel 122 close to the substrate 11 forms a second acute angle a2 with the substrate 11. The opening of the first acute angle a1 is directed toward a first direction D, and the opening of the second acute angle a2 is directed toward a second direction U. The first direction D is parallel to and opposite to the second direction U, and are respectively parallel to the substrate 11. The edge of the sub-pixel 12 includes a first tangent point N1 and a second tangent point N2 formed tangent to the second direction U. The second tangent point N2 is located on one side of the first tangent point N1 along a third direction R. The third direction R is parallel to the substrate 11 and the third direction R is perpendicular to the first direction D. The edge of the sub-pixel 12 includes a first edge portion L1 and a second edge portion L2 located between the first tangent point N1 and the second tangent point N2. The first edge portion L1 and the second edge portion L2 are arranged along the first direction D. The first dimming layer 13 is formed on the side of the sub-pixel 12 away from the substrate 11, and the first dimming layer 13 includes a plurality of focusing structures 130. The focusing structures 130 are formed around at least part of the sub-pixels 12. The focusing structures 130 include a first type of focusing structure 131 formed around a first type of sub-pixel 121. In the orthographic projection along the thickness direction of the substrate 11, the length of the first type of focusing structure 131 projected on the first edge portion L1 along the first direction D is greater than the length of the first type of focusing structure 131 projected on the second edge portion L2 along the second direction U, and / or the focusing structure 130 includes a second type of focusing structure 132 formed around a second type of sub-pixel 122. In the orthographic projection along the thickness direction of the substrate 11, the length of the second type of focusing structure 132 projected on the second edge portion L2 along the second direction U is greater than the length of the second type of focusing structure 132 projected on the first edge portion L1 along the first direction D. The second dimming layer 14 is formed on a side of the first dimming layer 13 away from the substrate 11 . The refractive index of the first dimming layer 13 is lower than that of the second dimming layer 14 .

[0051] The display panel 1 provided herein includes a substrate 11, a plurality of sub-pixels 12, and a light-focusing structure 130. The color shift of the display panel can be detected along four directions: a first direction D, a second direction U, a fourth direction L, and a third direction R, to evaluate the color shift of the display panel 1. The first direction D, the third direction R, the second direction U, and the fourth direction L are arranged counterclockwise, with two adjacent directions in the counterclockwise direction perpendicular to each other. The first direction D is parallel to and opposite to the second direction U, and the fourth direction L is parallel to and opposite to the third direction R. If the attenuation of the sub-pixels 12 in these four directions is inconsistent, asymmetric color shift will occur.

[0052] In the display panel 1, the sub-pixels 12 are formed on one side of the substrate 11. Due to the difference in the flatness of the film layer under different sub-pixels 12, the multiple sub-pixels 12 can be divided into a first type of sub-pixels 121 and a second type of sub-pixels 122. The first type of sub-pixels 121 and the second type of sub-pixels 122 have different inclination directions. Specifically, the surface of the first type of sub-pixel 121 close to the substrate 11 forms a first acute angle a1 with the substrate 11, and the surface of the second type of sub-pixel 122 close to the substrate 11 forms a second acute angle a2 with the substrate 11. The first acute angle a1 is the same as the first acute angle a2. The opening is oriented in the first direction D, and the opening at the second acute angle a2 is oriented in the second direction U. This results in the first type of sub-pixel 121 having a lower attenuation in the second direction U than the second type of sub-pixel 122 in the second direction U. Furthermore, the attenuation of the first type of sub-pixel 121 in the second direction U is lower than its attenuation in the first direction D, while the attenuation of the second type of sub-pixel 122 in the second direction U is higher than its attenuation in the first direction D. This can easily cause the display panel 1 to have asymmetric color shift in the first direction D and the second direction U. In the display panel 1 provided in the present application, a light-concentrating structure 130 is provided on the side of the sub-pixel 12 facing away from the substrate 11 to increase the attenuation on the side of the sub-pixel 12 with lower attenuation, thereby improving the asymmetric color shift.

[0053] Specifically, in the display panel 1 provided herein, the edge of the subpixel 12 includes a first tangent point N1 and a second tangent point N2 formed tangent to the second direction U. The second tangent point N2 is located on the side of the first tangent point N1 along the third direction R. That is, the first tangent point N1 is the end of the edge of the subpixel 12 closest to the fourth direction L, and the second tangent point N2 is the end of the edge of the subpixel 12 closest to the third direction R. The edge of the subpixel 12 includes a first edge portion L1 and a second edge portion L2 located between the first tangent point N1 and the second tangent point N2. The first edge portion L1 and the second edge portion L2 are arranged along the first direction D. In the subpixel 12, light emitted in the first direction D is primarily emitted from the second edge portion L2, and light emitted in the second direction U is primarily emitted from the first edge portion L1. The first dimming layer 13 and the second dimming layer 14 are sequentially arranged on the side of the sub-pixel 12 away from the substrate 11. The refractive index of the first dimming layer 13 is lower than the refractive index of the second dimming layer 14. The first dimming layer 13 and the second dimming layer 14 cooperate to adjust the large-angle light emitted by the sub-pixel 12 to improve the light extraction efficiency at the normal viewing angle and accelerate the attenuation of the large-angle light. The first dimming layer 13 includes a plurality of focusing structures 130. The plurality of focusing structures 130 include a first-type focusing structure 131 formed around the first-type sub-pixel 121. In the orthographic projection along the thickness direction of the substrate 11, the length of the first-type focusing structure 131 projected on the first edge portion L1 along the first direction D is greater than the length of the first-type focusing structure 131 projected on the second edge portion L2 along the second direction U. Since the length of the first-type focusing structure 131 projected on the edge portion of the sub-pixel 12 along the preset direction is greater, the adjustment effect of the first-type focusing structure 131 in this direction is better, and since the attenuation of the first-type sub-pixel 121 in the second direction U is greater than the projection length of the first-type focusing structure 131 on the edge portion L2 The attenuation degree is less than the attenuation degree in the first direction D, and the light output on the second direction U side is mainly emitted by the first edge portion L1. Therefore, by setting the length of the projection of the first type of focusing structure 131 on the first edge portion L1 along the first direction D to be larger, the first type of focusing structure 131 can have a greater attenuation adjustment effect on the second direction U, and the attenuation degree in the second direction U is improved, thereby reducing the attenuation difference between the first direction D and the second direction U of the first type of sub-pixel 121, and further reducing the difference between the attenuation degree of the first type of sub-pixel 121 in the second direction U and the attenuation degree of the second type of sub-pixel 122 in the second direction U, so as to improve the color deviation problem.

[0054] In the orthographic projection along the thickness direction of the substrate 11, the length of the first type of light-focusing structure 131 projected on the first edge portion L1 along the first direction D is specifically: Figure 4 is the orthographic projection along the thickness direction of the substrate 11. The dotted line C1 and the dotted line C2 represent the overlapping range of the projection of the first type of light-focusing structure 131 on the first edge portion L1 along the first direction D. Figure 4The projection of the first type of light-concentrating structure 131 along the first direction D onto the first edge portion L1 can cover the first edge portion L1. Therefore, the length of the projection of the first type of light-concentrating structure 131 along the first direction D onto the first edge portion L1 is the same as the length of the first edge portion L1. The distance between the intersection point N1 of the dotted line C1 and the first edge portion L1 and the intersection point X0 of the two straight lines in the first edge portion L1 is the first length, and the distance between the intersection point N2 of the dotted line C2 and the first edge portion L1 and the intersection point X0 of the two straight lines in the first edge portion L1 is the second length. The length of the projection of the first type of light-concentrating structure 131 along the first direction D onto the first edge portion L1 is the sum of the first length and the second length. Figure 5 As shown, Figure 5 The dotted line C1 and the dotted line C2 are the positive projections along the thickness direction of the substrate 11, and represent the overlapping range of the projection of the first type of light-focusing structure 131 on the first edge portion L1 along the first direction D and the first edge portion L1. The projection of the first type of light-focusing structure 131 on the first edge portion L1 along the first direction D does not cover the first edge portion L1, wherein the distance between the intersection X1 of the dotted line C1 and the first edge portion L1 and the two straight line intersections X0 in the first edge portion L1 is the first length, the distance between the intersection X2 of the dotted line C2 and the first edge portion L1 and the two straight line intersections X0 in the first edge portion L1 is the second length, and the length of the projection of the first type of light-focusing structure 131 on the first edge portion L1 along the first direction D is the sum of the first length and the second length.

[0055] Specifically, one of the length of the first type light-concentrating structure 131 projected on the first edge portion L1 along the first direction D and the length of the first type light-concentrating structure 131 projected on the second edge portion L2 along the second direction U may be zero.

[0056] And / or, the focusing structure 130 includes a second type of focusing structure 132 formed around the second type of sub-pixel 122, and in the orthographic projection along the thickness direction of the substrate 11, the length of the second type of focusing structure 132 projected on the second edge portion L2 along the second direction U is greater than the length of the second type of focusing structure 132 projected on the first edge portion L1 along the first direction D. Since the length of the second type of focusing structure 132 projected on the edge portion of the sub-pixel 12 along the preset direction is greater, the adjustment effect of the second type of focusing structure 132 in this direction is better, and since the attenuation degree of the second type of sub-pixel 122 in the first direction D is less than that in the first direction D, Regarding the attenuation degree in the two directions U, the light output on the first direction D side is mainly emitted by the second edge portion L2. Therefore, by setting the length of the projection of the second type of focusing structure 132 on the second edge portion L2 along the second direction U to be larger, the second type of focusing structure 132 can have a greater attenuation adjustment effect on the first direction D, thereby improving the attenuation degree in the first direction D, thereby reducing the attenuation difference between the first direction D and the second direction U of the second type of sub-pixel 122, and further reducing the difference in the attenuation degree of the second type of sub-pixel 122 in the first direction D and the attenuation degree of the first type of sub-pixel 121 in the first direction D, thereby improving the color deviation problem.

[0057] Specifically, one of the length of the second type light-concentrating structures 132 projected on the second edge portion L2 along the second direction U and the length of the second type light-concentrating structures 132 projected on the first edge portion L1 along the first direction D may be zero.

[0058] That is, in the display panel 1 provided in the present application, the color deviation problem is improved by reducing the difference between the attenuation degree of the first type sub-pixel 121 in the second direction U and the attenuation degree of the second type sub-pixel 122 in the second direction U, and / or reducing the difference between the attenuation degree of the second type sub-pixel 122 in the first direction D and the attenuation degree of the first type sub-pixel 121 in the first direction D, thereby improving the display effect of the display panel 1.

[0059] In one possible implementation, Figure 2 As shown, the sub-pixel 12 includes a first electrode, a light-emitting layer, and a second electrode stacked in a direction away from the substrate 11. The first electrode of the first type sub-pixel 121 forms a first acute angle a1 with the substrate 11 on its surface near the substrate 11, while the first electrode of the second type sub-pixel 122 forms a second acute angle a2 with the substrate 11 on its surface near the substrate 11. The opening at the first acute angle a1 faces the first direction D, while the opening at the second acute angle a2 faces the second direction U. The first electrode of the first type sub-pixel 121 and the first electrode of the second type sub-pixel 122 have different inclination directions, resulting in different inclination directions between the first type sub-pixel 121 and the second type sub-pixel 122.

[0060] Specifically, if Figure 2As shown, in the first type of sub-pixel 121, the distance between the end closest to the second direction U and the substrate 11 is a first distance H1, and the distance between the end closest to the first direction D and the substrate 11 is a first distance, the first distance is smaller than the second distance, and the difference between the first distance and the second distance is 0.03 μm to 0.08 μm. In the second type of sub-pixel 122, the distance between the end closest to the second direction U and the substrate 11 is a third distance, and the distance between the end closest to the first direction D and the substrate 11 is a fourth distance, the fourth distance is smaller than the third distance, and the difference between the fourth distance and the third distance is 0.06 μm to 0.08 μm.

[0061] In the above embodiment, if Figure 3 As shown, the multiple sub-pixels 12 include at least three colors of sub-pixels 12, the multiple sub-pixels 12 include different first color sub-pixels 123, second color sub-pixels 124 and third color sub-pixels 125, the first type of sub-pixels 121 include first color sub-pixels 123, and the second type of sub-pixels 122 include second color sub-pixels 124 and third color sub-pixels 125.

[0062] The first color sub-pixel 123 may be a green sub-pixel 12 , the second color sub-pixel 124 may be a blue sub-pixel 12 , and the third color sub-pixel 125 may be a red sub-pixel 12 .

[0063] Specifically, the shape of the orthographic projection of the sub-pixel 12 on the substrate 11 can be a regular shape, such as a rectangle, a circle, a polygon, etc., or an irregular shape, which is not particularly limited in this application.

[0064] When it is a rectangle and the two opposite sides of the rectangle are parallel to the first direction D, the number of the first tangent point N1 and the second tangent point N2 can be multiple, and any one of the first tangent point N1 and any one of the second tangent point N2 can be used to divide the first edge portion L1 and the second edge portion L2.

[0065] In one possible implementation, Figure 3 and Figure 4 As shown, the light-concentrating structure 130 includes a first type of light-concentrating structure 131 , and the first type of light-concentrating structure 131 is disposed around at least a portion of the first edge portion L1 .

[0066] In the above-described method, the first-type light-concentrating structure 131 can be disposed only around at least a portion of the first edge portion L1, and not around the second edge portion L2. This allows light emitted from the side of the first edge portion L1 to be adjusted, thereby increasing the attenuation rate and degree of the first-type sub-pixels 121 in the second direction U, thereby reducing the color shift difference between the first-type sub-pixels 121 in the first direction D and the second direction U. Furthermore, because the attenuation degree of the first-type sub-pixels 121 in the second direction U is less than the attenuation degree of the second-type sub-pixels 122 in the second direction U, by increasing the attenuation rate and degree of the first-type sub-pixels 121 in the second direction U through the first-type light-concentrating structure 131, the difference in attenuation degree between the first-type sub-pixels 121 and the second-type sub-pixels 122 in the second direction U can be reduced, thereby improving the color shift problem of the display panel 1.

[0067] In one possible implementation, Figure 3 and Figure 4 As shown, the first type of light-concentrating structure 131 includes a strip structure arranged around a portion of the first type of sub-pixel 121 in the circumferential direction, or as shown in FIG. Figure 6 As shown, the first type of light-concentrating structure 131 includes a plurality of first type of light-concentrating portions 1311 , and the plurality of first type of light-concentrating portions 1311 are arranged along a portion of the circumference of the first type of sub-pixel 121 .

[0068] In the above embodiment, the first type of focusing structure 131 includes a strip structure arranged around a portion of the first type of sub-pixel 121 in the circumferential direction. The design of the strip structure can, on the one hand, enable the length of the projection of the first type of focusing structure 131 on the first edge portion L1 along the first direction D to be set to be larger, and on the other hand, it can facilitate preparation.

[0069] In the above embodiment, the first-type light-focusing structure 131 includes a plurality of first-type light-focusing portions 1311, and the plurality of first-type light-focusing portions 1311 are arranged along a portion of the circumference of the first-type sub-pixel 121, and there are gaps between adjacent first-type light-focusing portions 1311. Therefore, on the one hand, the first-type light-focusing portions 1311 can be evenly distributed so as to make the adjustment effect more uniform. On the other hand, it is convenient to control the overall adjustment degree of the first-type light-focusing structure 131 under the premise of uniform adjustment, so as to reduce the attenuation difference of light in the first direction D and the second direction U of the first-type sub-pixel 121.

[0070] Specifically, when the first type of light-focusing structure 131 includes multiple first type of light-focusing portions 1311, the length of the first type of light-focusing structure 131 projected on the first edge portion L1 along the first direction D is the sum of the lengths of the projections of each first type of light-focusing portion 1311 along the first direction D on the first edge portion L1.

[0071] In one possible implementation, Figure 7As shown, the focusing structure 130 includes a first-type focusing structure 131, which is arranged around the circumference of the first-type sub-pixel 121. The first-type focusing structure 131 includes a first part 1312 and a second part 1313. The first part 1312 is a strip structure arranged around a part of the circumference of the first-type sub-pixel 121, and the second part 1313 includes a plurality of first-type focusing portions 1311, and the plurality of first-type focusing portions 1311 are arranged along a part of the circumference of the first-type sub-pixel 121.

[0072] In the above embodiment, the first-type light-concentrating structure 131 can include either a first portion 1312 distributed along a strip or multiple first-type light-concentrating portions 1311 distributed at intervals. Within the same distribution range, the first portion 1312 of the strip structure receives a wider range of side-view light, thereby enhancing the attenuation level. The first-type light-concentrating portions 1311 distributed at intervals have gaps between them, allowing side-view light to propagate through the gaps. As a result, the first-type light-concentrating portions 1311 distributed at intervals have a smaller reception range for side-view light, thereby enhancing the attenuation level less. Therefore, a strip structure or multiple first-type light-concentrating portions 1311 distributed at intervals can be configured according to specific adjustment requirements in different directions.

[0073] In one possible embodiment, Figure 7 As shown, the first portion 1312 is disposed around the first edge portion L1 , and the second portion 1313 is disposed around the second edge portion L2 .

[0074] In the above embodiment, since the attenuation degree of the first type sub-pixel 121 in the second direction U is less than its attenuation degree in the first direction D, the first part 1312 is arranged around the first edge portion L1 and the second part 1313 is arranged around the second edge portion L2, so that the adjustment effect on the second direction U can be greater than the adjustment effect on the first direction D, thereby reducing the difference between the attenuation degree of the first type sub-pixel 121 in the second direction U and its attenuation degree in the first direction D, thereby improving color deviation.

[0075] In one possible implementation, Figure 7 As shown, the light-concentrating structure 130 further includes a third light-concentrating structure 133 formed around the second sub-pixel 122 . The third light-concentrating structure 133 is a ring-shaped structure disposed around the second sub-pixel 122 .

[0076] In the above embodiment, the light-concentrating structure 130 may include a first-type light-concentrating structure 131 and a third-type light-concentrating structure 133. The first-type light-concentrating structure 131 is formed around the first-type sub-pixel 121, and the third-type light-concentrating structure 133 is formed around the second-type sub-pixel 122. The third-type light-concentrating structure 133 is used to fully surround the second-type sub-pixel 122, converting the light emitted from the second-type sub-pixel 122 at a side angle to light emitted at a front angle, thereby increasing the amount of light emitted at the front angle and improving the brightness of the display panel 1. The first-type light-concentrating structure 131 having a first portion 1312 and a second portion 1313 may also be used. The first-type light-concentrating structure 131 can reduce the difference between the attenuation of the first-type sub-pixel 121 in the second direction U and its attenuation in the first direction D, thereby improving color shift. At the same time, since the attenuation degree of the first type of sub-pixel 121 in the first direction D will be greater than the attenuation degree of the second type of sub-pixel 122 in the first direction D, the third type of focusing structure 133 is set, and the third type of focusing structure 133 is strip-shaped on the second edge side of the second type of sub-pixel 122, and the adjustment effect is strong, the attenuation speed of the second type of sub-pixel 122 in the first direction D can be increased. By setting the second part 1313, the second part 1313 is set around the second edge portion L2 of the first type of sub-pixel 121, including a plurality of spaced first type focusing portions 1311, and the adjustment effect of the plurality of first type focusing portions 1311 is weaker than that of the third type of focusing structure 133 with a strip structure, thereby reducing the difference in the attenuation degree of the first type of sub-pixel 121 in the first direction D and the attenuation degree of the second type of sub-pixel 122 in the first direction D, thereby improving the color deviation.

[0077] In one possible implementation, Figure 8 and Figure 9 As shown, the light-concentrating structure 130 includes a second type of light-concentrating structure 132 , and the second type of light-concentrating structure 132 is disposed around at least a portion of the second edge portion L2 .

[0078] In the above embodiment, the second-type light-concentrating structure 132 may be disposed only around at least a portion of the second edge portion L2 of the second-type sub-pixel 122, and not around the first edge portion L1 of the second-type sub-pixel 122. Thus, light emitted from the second-type sub-pixel 122 is only regulated from the second edge portion L2, thereby increasing the attenuation rate and degree of the second-type sub-pixel 122 in the first direction D, thereby reducing the color shift difference between the second-type sub-pixel 122 in the first direction D and the second direction U. Furthermore, because the attenuation degree of the second-type sub-pixel 122 in the first direction D is less than the attenuation degree of the first-type sub-pixel 121 in the first direction D, by increasing the attenuation rate and degree of the second-type sub-pixel 122 in the first direction D via the second-type light-concentrating structure 132, the difference between the attenuation degree of the second-type sub-pixel 122 in the first direction D and the attenuation degree of the first-type sub-pixel 121 in the first direction D can be reduced, thereby improving the color shift problem of the display panel 1.

[0079] In one possible implementation, Figure 9 As shown, the second type of light-concentrating structure 132 includes a strip structure arranged around a portion of the second type of sub-pixel 122 in the circumferential direction, or as shown in FIG. Figure 10 As shown, the second type of light-concentrating structure 132 includes a plurality of second type of light-concentrating portions 1321 , and the plurality of second type of light-concentrating portions 1321 are arranged along a portion of the circumference of the second type of sub-pixel 122 .

[0080] In the above embodiment, the second type of focusing structure 132 includes a strip structure arranged around a portion of the second type of sub-pixel 122 in the circumferential direction. The design of the strip structure can, on the one hand, enable the length of the second type of focusing structure 132 projected on the second edge portion L2 along the second direction U to be set to be larger, and on the other hand, it can be easily prepared.

[0081] In the above embodiment, the second-type light-focusing structure 132 includes a plurality of second-type light-focusing portions 1321, and the plurality of second-type light-focusing portions 1321 are arranged along a portion of the circumference of the second-type sub-pixel 122, and there are gaps between adjacent second-type light-focusing portions 1321. Therefore, on the one hand, the second-type light-focusing portions 1321 can be evenly distributed so as to make the adjustment effect more uniform. On the other hand, it is convenient to control the overall adjustment degree of the second-type light-focusing structure 132 under the premise of uniform adjustment, so as to reduce the attenuation difference of the light in the first direction D and the second direction U of the second-type sub-pixel 122.

[0082] Specifically, when the second type of light-focusing structure 132 includes multiple second type of light-focusing portions 1321, the length of the second type of light-focusing structure 132 projected on the second edge portion L2 along the second direction U is the sum of the lengths of the projections of each second type of light-focusing portion 1321 along the second direction U on the second edge portion L2.

[0083] In one possible implementation, Figure 11As shown, the focusing structure 130 includes a second type of focusing structure 132, and the second type of focusing structure 132 includes a third part 1322 and a fourth part 1323 arranged along a third direction R and spaced apart. The third part 1322 includes a first sub-part 1324 arranged around a part in the first edge and a second sub-part 1325 arranged around a part in the second edge. In the orthographic projection along the thickness direction of the substrate 11, the length of the first sub-part 1324 is smaller than the length of the second sub-part 1325; the fourth part 1323 includes a third sub-part 1326 arranged around a part in the first edge and a fourth sub-part 1327 arranged around a part in the second edge. In the orthographic projection along the thickness direction of the substrate 11, the length of the third sub-part 1326 is smaller than the length of the fourth sub-part 1327.

[0084] In the above embodiment, in the orthographic projection along the thickness direction of the substrate 11, by setting the length of the first sub-portion 1324 to be smaller than the length of the second sub-portion 1325, and setting the length of the third sub-portion 1326 to be smaller than the length of the fourth sub-portion 1327, the length of the second type of light-focusing structure 132 projected on the second edge portion L2 along the second direction U can be made greater than the length of the second type of light-focusing structure 132 projected on the first edge portion L1 along the first direction D, so that the regulating effect of the second type of light-focusing structure 132 on the attenuation degree of light output in the second direction U is smaller than the regulating effect on the attenuation degree of light output in the first direction D, so that the attenuation degree of the second type of sub-pixel 122 in the second direction U is greater than the attenuation degree in the first direction D, and the difference between the attenuation degree of the second type of sub-pixel 12 in the second direction U and the attenuation degree of the first direction D is reduced through the above adjustment.

[0085] At the same time, since the third part 1322 and the fourth part 1323 can simultaneously adjust the light output of the second type sub-pixel 122 in the fourth direction L and the third direction R, the second type sub-pixel 12 can have a greater attenuation degree and a greater reduction in the light output in the first direction D, the fourth direction L and the third direction R, and a smaller attenuation degree and a smaller reduction in the light output in the second direction U, thereby improving the brightness ratio of the second type sub-pixel 12 in the second direction U, so that the brightness change trend in the second direction U matches the brightness change trend in the first direction D, the fourth direction L and the third direction R, thereby reducing color deviation.

[0086] In one possible implementation, Figure 11 As shown, the third portion 1322 and the fourth portion 1323 are symmetrically arranged along the first direction D and the second direction U, respectively, to achieve symmetrical adjustment of light emission of the second type of sub-pixels 122 and improve the display effect.

[0087] In one possible implementation, Figure 11As shown, the third portion 1322 includes a strip structure arranged around a portion of the second type of sub-pixel 122 in the circumferential direction, or as shown in FIG. Figure 12 As shown, the third portion 1322 includes a plurality of second-type light-focusing portions 1321, and the plurality of second-type light-focusing portions 1321 are arranged along a portion of the second-type sub-pixel 122 in the circumferential direction; the fourth portion 1323 includes a strip structure arranged around a portion of the second-type sub-pixel 122 in the circumferential direction, or the fourth portion 1323 includes a plurality of second-type light-focusing portions 1321, and the plurality of second-type light-focusing portions 1321 are arranged along a portion of the second-type sub-pixel 122 in the circumferential direction.

[0088] In the above embodiment, the third part 1322 and the fourth part 1323 respectively include a strip structure arranged around a portion of the second type sub-pixel 122 in the circumferential direction. The design of the strip structure can, on the one hand, enable the second sub-part 1325 and the fourth sub-part 1327 in the third part 1322 and the fourth part 1323 to have a larger length projected on the second edge part L2 along the second direction U, and enable the first sub-part 1324 and the third sub-part 1326 in the third part 1322 and the fourth part 1323 to have a larger length projected on the first edge part L1 along the first direction D; on the other hand, it can facilitate preparation.

[0089] In the above embodiment, the third part 1322 and the fourth part 1323 respectively include a plurality of second-type focusing portions 1321, and the plurality of second-type focusing portions 1321 are arranged along a portion of the circumference of the second-type sub-pixel 122, and there are gaps between adjacent second-type focusing portions 1321. Therefore, on the one hand, the second-type focusing portions 1321 can be evenly distributed so as to make the adjustment effect more uniform. On the other hand, it is convenient to control the overall adjustment degree of the second-type focusing structure 132 under the premise of uniform adjustment, so as to reduce the attenuation difference of light in the first direction D and the second direction U of the second-type sub-pixel 122.

[0090] Specifically, when the second-type light-focusing structure 132 includes multiple second-type light-focusing portions 1321, the length of the second-type light-focusing structure 132 projected on the second edge portion L2 along the second direction U is the sum of the lengths of the projections of each second-type light-focusing portion 1321 along the second direction U on the second edge portion L2, and the length of the second-type light-focusing structure 132 projected on the first edge portion L1 along the first direction D is the sum of the lengths of the projections of each second-type light-focusing portion 1321 along the first direction D on the first edge portion L1.

[0091] In one possible implementation, Figure 8 As shown, the functional layer 15 is further included and is located on the side of the sub-pixel 12 facing away from the substrate 11 . The light-concentrating structure 130 is formed on the side of the functional layer 15 facing away from the substrate 11 .

[0092] In the above embodiment, if Figure 8As shown, the functional layer 15 includes an encapsulation layer 151, which is used to encapsulate the sub-pixels 12 and may include an inorganic layer, an organic base layer, and an inorganic layer stacked in a direction away from the substrate 11. The organic layer can play a flattening role, so that the side of the encapsulation layer 151 facing away from the substrate 11 is a flat surface. The focusing structure 130 is formed on the side of the encapsulation layer 151 facing away from the substrate 11. On the one hand, it can form the focusing structure 130 on a flat surface, improving the performance of the focusing structure 130. On the other hand, it can ensure the encapsulation effect of the encapsulation layer 151 on the sub-pixels 12, thereby ensuring the luminous yield of the sub-pixels 12.

[0093] like Figure 13 As shown, the functional layer 15 may further include a touch layer 152 located on a side of the encapsulation layer 151 facing away from the substrate 11 , and the light-concentrating structure 130 may be formed on a side of the touch layer 152 facing away from the substrate 11 .

[0094] The second dimming layer 14 is disposed in contact with the first dimming layer 13 to ensure that light is converged when it enters the high refractive index medium from the low refractive index medium.

[0095] In a feasible embodiment, the focusing structure 130 is arranged to protrude from the side surface of the substrate 11 to the side away from the substrate 11, so as to achieve a focusing effect on the side view light, so as to convert the side view light into the front view light, thereby increasing the attenuation speed.

[0096] In one possible implementation, Figure 13 、 Figure 14 and Figure 15 As shown, the cross-sectional shape of the light-concentrating structure 130 along the thickness direction of the substrate 11 is semicircular, triangular, or trapezoidal. A hemispherical structure with a semicircular cross-section can converge light through the arcuate surface corresponding to the semicircle. A prismatic structure with a trapezoidal or triangular cross-section can converge light through the inclined side surfaces. Furthermore, light-concentrating structures 130 with these shapes are easy to manufacture, have a high yield, and are easily controlled in terms of parameters.

[0097] The present application also provides a display device 2, such as Figure 16 As shown, it includes any one of the display panels 1 provided in the above embodiments.

[0098] In the display device 2, since the display panel 1 adopts the focusing structure 130 to uniformly adjust the attenuation speed of light emitted from the sub-pixel 12 in different directions, the color deviation problem can be improved, thereby improving the display effect of the display panel 1, and further improving the performance of the display device 2, which helps to improve the user experience.

[0099] The display device 2 can be a mobile terminal such as a mobile phone or a laptop computer, or a fixed terminal such as a television or a computer monitor, or can also be a wearable device such as a watch, etc., and this application does not make any special restrictions.

[0100] The above are merely preferred embodiments of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
