Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the basic concepts disclosed and suggested by the embodiments of the present invention, all other embodiments obtained by those skilled in the art are within the scope of protection of the present invention.

[0030] Figure 1 FIG. 1 is a schematic diagram of a structure of a display panel in the prior art. Figure 1 As shown, the display panel 10 includes a first display area 11 and a second display area 12 connected to each other, and the display panel also includes a substrate 13, a light emitting unit 14 located on one side of the substrate 13, a color filter unit 15 located on the side of the light emitting unit 14 away from the substrate 13, and a shading unit 16 located between adjacent color filter units 15; along the direction from the first display area 11 to the second display area 12, the first display area 11 of the display panel 10 is a flat area, and the second display area 12 is a curved area. When the bending degree is greater than the bending degree of the first display area 11, there is a difference in the deflection direction of the light emitted from the first display area 11 and the light emitted from the second display area 12, and then a serious color cast problem occurs with the change of viewing angle, which seriously affects the display effect.

[0031] To solve the above technical problems, an embodiment of the present invention provides a display panel, comprising: a first display area and a second display area connected to each other, wherein the curvature of the bending at the light emitting surface of the first display area is smaller than the curvature of the bending at the light emitting surface of the second display area; the display panel also comprises: a substrate; a light emitting unit located on one side of the substrate, wherein the light emitting unit comprises a first light emitting unit located in the first display area and a second light emitting unit located in the second display area; a color filter layer located on a side of the light emitting unit away from the substrate, wherein the color filter layer comprises a plurality of color filter units; a light shielding layer located on one side of the color filter unit, wherein the light shielding layer comprises a plurality of first light shielding units located in the first display area and a plurality of second light shielding units located in the second display area; the first light shielding unit comprises a first surface close to a side of the substrate and a second surface away from a side of the substrate, wherein the coverage area of ​​the first surface is smaller than the coverage area of ​​the second surface along the thickness direction of the display panel; the second light shielding unit comprises a third surface close to a side of the substrate and a fourth surface away from a side of the substrate, wherein the coverage area of ​​the third surface is larger than the coverage area of ​​the fourth surface along the thickness direction of the display panel. By reasonably adjusting the shapes of the first shading unit located in the first display area and the second shading unit located in the second display area, the light emitting angle of the light emitted through the first display area is made the same as or similar to the light emitting angle of the light emitted through the second display area, thereby reducing the display difference between the first display area and the second display area and ensuring the display uniformity of the display panel.

[0032] The above is the core idea of ​​the present invention. The technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Figure 2 A schematic diagram of the structure of a display panel provided by an embodiment of the present invention, Figure 3 A schematic diagram of the structure of another display panel provided by an embodiment of the present invention is shown in FIG. Figure 2 and Figure 3As shown, the display panel 100 includes: a first display area 101 and a second display area 102 which are connected to each other, the curvature of the first display area 101 at the light emitting surface is smaller than the curvature of the second display area 102 at the light emitting surface, and there is a part of the display area in the display panel that can be bent toward its light emitting side or away from its light emitting side, and the curvature is the degree to which the curved surface deviates from the plane, and the greater the curvature of the curved surface, the greater the curvature of the curved surface. The display panel 100 further includes: a base substrate 103; a light emitting unit 104 located on one side of the base substrate 103, the light emitting unit 104 including a first light emitting unit 1041 located in the first display area 101 and a second light emitting unit 1042 located in the second display area 102; a color filter layer 105 located on a side of the light emitting unit 104 away from the base substrate 103, the color filter layer 105 including a plurality of color filter units 1051; a light shielding layer 106 located on one side of the color filter unit 1051, the light shielding layer 106 including a plurality of first light shielding units 107 located in the first display area 101 and a plurality of first light shielding units 108 located in the second display area 102; The display panel 100 includes a plurality of second shading units 108 in the domain 102; the first shading unit 107 includes a first surface 109 close to the side of the substrate 103 and a second surface 110 away from the side of the substrate 103, and along the thickness direction of the display panel 100, the coverage area of ​​the first surface 109 is smaller than the coverage area of ​​the second surface 110; the second shading unit 108 includes a third surface 111 close to the side of the substrate 103 and a fourth surface 112 away from the side of the substrate 103, and along the thickness direction of the display panel 100, the coverage area of ​​the third surface 111 is larger than the coverage area of ​​the fourth surface 112.

[0034] The display panel 100 includes a first display area 101 and a second display area 102 connected to each other. The curvature of the light-emitting surface of the first display area 101 is smaller than the curvature of the light-emitting surface of the second display area 102. The first display area 101 is a plane area, that is, the curvature of the first display area 101 is 0, and the second display area 102 is a curved area. The display panel 100 may include other numbers of first display areas and second display areas 102. The embodiment of the present invention does not specifically limit the number of the first display areas 101 and the second display areas 102. The color filter layer 105 is located on the side of the light-emitting unit 104 away from the base substrate 103. The color filter layer 105 in the first display area 101 and the second display area 102 includes a plurality of color filter units 1051. The color filter unit 1051 may include a red color filter unit, a green color filter layer and a blue color filter layer to ensure the color purity of the emitted light. The light shielding layer 106 can be arranged between adjacent color filter units 1051 and located on the side of the color filter layer 105 close to the base substrate 103 or on the side of the color filter layer 105 far from the base substrate 103. The specific arrangement can be selected according to actual design requirements, and the embodiment of the present invention does not specifically limit it. At the same time, the light shielding layer 106 can be a single-layer structure or a double-layer structure to ensure the light shielding effect, thereby realizing the adjustment of the exit angle of the exit light. Figure 2 As shown, the shading unit is exemplarily located on the side of the color filter layer 105 away from the base substrate 103, and the shading unit is a single-sided structure. Figure 3As shown, the shading unit is exemplarily located between adjacent color filter units 1051, and the shading unit is a single-sided structure. Specifically, a first shading unit 107 is provided corresponding to the first display area 101, and the first shading unit 107 includes a first surface 109 close to the side of the substrate 103 and a second surface 110 away from the side of the substrate 103. Along the thickness direction of the display panel 100, the coverage area of ​​the first surface 109 is smaller than the coverage area of ​​the second surface 110, and the second surface 110 between adjacent first shading units 107 defines the light emitting range of the corresponding light emitting unit 104; a second shading unit 108 is provided corresponding to the second display area 102, and the second shading unit 108 includes a third surface 111 close to the side of the substrate 103 and a fourth surface 112 away from the side of the substrate 103. Along the thickness direction of the display panel 100, the coverage area of ​​the third surface 111 is larger than the coverage area of ​​the fourth surface 112, and the fourth surface 112 between adjacent second shading units 108 defines the light emitting range of the corresponding light emitting unit 104. Since the curvature of the light emitting surface of the first display area 101 is smaller than that of the light emitting surface of the second display area 102, in order to avoid the light emitting area of ​​the second display area 102 from being deflected as the curvature of the curvature increases, resulting in a decrease in the display brightness of the second display area 102, the shape of the first shading unit 107 is adjusted to be different from the shape of the second shading unit 108, so that the light emitted by the first light emitting unit located between adjacent first shading units 107 and the second light emitting unit located between adjacent second shading units 108 have the same or similar light emitting angles, thereby making the first display area 101 and the second display area 102 have the same display brightness, avoiding display deviation at different viewing angles, and ensuring the display effect of the display panel 100.

[0035] The embodiment of the present invention ensures that the light output brightness of the first display area is the same as the light output brightness of the second display area by reasonably setting the shapes of the first shading unit located in the first display area and the second shading unit located in the second display area, thereby avoiding display deviation at different viewing angles and ensuring the normal display effect of the display panel.

[0036] Continue to refer Figure 2 and Figure 3Optionally, in any plane perpendicular to the light emitting surface of the display panel 100, the first light emitting unit 1041 includes a first side 113 away from one side of the base substrate 103 and perpendicular to the first direction (the Y direction shown in the figure), a second side 114 close to the first light shielding unit 107 and intersecting with the first side 113, and a first intersection A1 connecting the first side 113 and the second side 114, the first light shielding unit 107 includes a third side 115 away from one side of the base substrate 103 and perpendicular to the first direction, a fourth side 116 close to the second side 114 and intersecting with the third side 115, and a second intersection A2 connecting the third side 115 and the fourth side 116, and the angle between the first intersection A1 and the second intersection A2 and the first direction is a first angle θ1; the second The light emitting unit 1042 includes a fifth side 117 away from one side of the base substrate 103 and perpendicular to the first direction, a sixth side 118 close to the second light shading unit 108 and intersecting with the fifth side 117, and a third intersection A3 connecting the fifth side 117 and the sixth side 118. The second light shading unit 108 includes a seventh side 119 away from one side of the base substrate 103 and perpendicular to the first direction, an eighth side 120 close to the sixth side 118 and intersecting with the seventh side 119, and a fourth intersection A4 connecting the seventh side 119 and the eighth side 120. The angle between the line between the third intersection A3 and the fourth intersection A4 and the first direction is the second angle θ2, satisfying θ1-θ2≤5°; wherein the first direction is the thickness direction of the display panel 100 in the first display area 101.

[0037] Among them, in any plane perpendicular to the light emitting surface of the display panel 100, that is, in any plane parallel to the first direction, the difference between the first angle between the line between the first intersection A1 of the first light emitting unit 1041 and the second intersection A2 of the first light shielding unit 107 and the first direction and the second angle between the line between the third intersection A3 of the second light emitting unit 1042 and the fourth intersection A4 of the second light shielding unit 108 and the first direction is between 0° and 5°, that is, the edge light emitted through the first light emitting unit 1041 passes through the first intersection A2 of the first light shielding unit 107 corresponding thereto. The angle of the edge emission of the second surface 110 is the same or similar to the angle of the edge light emitted by the second light emitting unit 1042 through the edge of the fourth surface 112 of the corresponding second shading unit 108, so that the range of the light emitted by the first light emitting unit 1041 of the first display area 101 and the second light emitting unit 1042 of the second display area 102 is the same or similar, and the display effect of the second display area 102 of the display panel 100 is the same or similar to the display effect of the first display area 101, thereby ensuring the display uniformity of the display panel 100.

[0038] Continue to refer Figure 2 and Figure 3, optionally, the first angle θ1 is equal to the second angle θ2.

[0039] To ensure that the first display area 101 and the second display area 102 have the same display effect, the first angle θ1 is equal to the second angle θ2, and the display effect of each part of the display panel 100 is consistent, thereby improving the user experience.

[0040] Optional, Figure 4 A schematic diagram of the structure of another display panel provided by an embodiment of the present invention is shown in FIG. Figure 4 As shown, along the first direction, the extension height of the first light shielding unit 107 is greater than the extension height of the second light shielding unit 108.

[0041] Among them, the extension height of the first shading unit 107 can be adjusted to be greater than the extension height of the second shading unit 108 in the first direction, and the second shading unit 108 is thinned, so that the exit angle of the light emitted through the first shading unit 107 is smaller than the exit angle of the light emitted through the second shading unit 108, thereby ensuring that in the direction from the first display area 101 to the second display area 102, as the bending curvature changes, by controlling the extension height of the shading unit, the first angle θ1 in the first shading unit 107 and the second angle θ2 in the second shading unit 108 are achieved, satisfying θ1-θ2≤5°.

[0042] Optional, Figure 5 A schematic diagram of the structure of another display panel provided by an embodiment of the present invention is shown in FIG. Figure 5 As shown, along the first direction, the second light-shielding unit 108 includes a first sub-light-shielding unit 1081 located on the side of the color filter layer 105 close to the base substrate 103 and a second sub-light-shielding unit 1082 located on the side of the color filter layer 105 away from the base substrate 103; along the first direction, the first sub-light-shielding unit 1081 and the second sub-light-shielding unit 1082 at least partially overlap.

[0043] Among them, the second shading unit 108 located in the second display area 102 is set to a double-layer structure, the first sub-shading unit 1081 is located on the side of the color filter layer 105 close to the base substrate 103, and the second sub-shading unit 1082 is located on the side of the color filter layer 105 away from the base substrate 103. By setting the first sub-shading unit 1081 and the second sub-shading unit 1082, the adjustment of the light output angle of the outgoing light of the second display area 102 is further improved. In the first direction, the first sub-shading unit 1081 and the second sub-shading unit 1082 at least partially overlap, and the coverage area of ​​the first sub-shading unit 1081 is larger than the coverage area of ​​the second sub-shading unit 1082. For example, Figure 5As shown, the projection area of ​​the second sub-shading unit 1082 completely falls within the projection area of ​​the first sub-shading unit 1081, and the first sub-shading unit 1081 and the second sub-shading unit 1082 are between adjacent color filter units 1051. It is ensured that as the curvature of the display panel 100 changes, the shapes and coverage areas of the first sub-shading unit 1081 and the second sub-shading unit 1082 are reasonably adjusted, and then the light emitted by the second light emitting unit 1042 is adjusted, so that the display effect of the second display area 102 is the same as or similar to that of the first display area 101.

[0044] Figure 6 for Figure 5 A partial enlarged view of Figure 5 and Figure 6 As shown, optionally, the first sub-shading unit 1081 includes a ninth side 121 away from one side of the base substrate 103 and perpendicular to the first direction, a tenth side 122 close to the sixth side 118 and intersecting with the ninth side 121, and a fifth intersection A5 connecting the ninth side 121 and the tenth side 122, and the angle between the line connecting the third intersection A3 and the fifth intersection A5 and the first direction is a third angle θ3; the second sub-shading unit 1082 includes an eleventh side 123 away from one side of the base substrate 103 and perpendicular to the first direction, a twelfth side 124 close to the sixth side 118 and intersecting with the eleventh side 123, and a sixth intersection A6 connecting the eleventh side 123 and the twelfth side 124, and the angle between the line connecting the third intersection A3 and the sixth intersection A6 and the first direction is a fourth angle θ4, wherein θ3≥θ4.

[0045] Among them, since the coverage area of ​​the first sub-shading unit 1081 is larger than the coverage area of ​​the second sub-shading unit 1082, in order to prevent the light emitted through the edge of the second light emitting unit 1042 from being absorbed by the first sub-shading unit 1081, affecting the light emission range of the second light emitting unit 1042. A third angle θ3 formed by a line connecting the third intersection A3 connecting the fifth side 117 and the sixth side 118 in the second light emitting unit 1042 and the fifth intersection A5 connecting the ninth side 121 and the tenth side 122 in the first sub-light shading unit 1081 and the first direction is greater than a fourth angle θ4 formed by a line connecting the third intersection A3 connecting the fifth side 117 and the sixth side 118 in the second light emitting unit 1042 and the sixth intersection A6 connecting the eleventh side 123 and the twelfth side 124 in the second sub-light shading unit 1082 and the first direction, so that the large-angle edge light emitted by the second light emitting unit 1042 will not be blocked by the first sub-light shading unit 1081, thereby ensuring the emission range of the light emitted from the second display area 102, thereby achieving the same or similar display effect as the first display area 102.

[0046] Optional, Figure 7 A schematic diagram of the structure of another display panel provided by an embodiment of the present invention, Figure 8 for Figure 7 A partial enlarged view of Figure 7 and Figure 8 As shown, the first sub-light shielding unit 1081 includes a side wall 125 close to the second light output unit 1042, the side wall 125 intersects with the first direction, and the angle between the side wall 125 and the first direction is a fifth angle θ5, wherein θ5≥θ2.

[0047] Among them, in any plane perpendicular to the light emitting surface of the display panel 100, the side wall 125 of the first sub-shading unit 1081 close to the second light emitting unit 1042 is tilted, that is, the angle between the side wall 125 and the first direction forms a certain angle, so as to ensure the light emitting effect of the second light emitting unit 1042, and the second angle θ2 between the line between the third intersection A3 connecting the fifth side 117 and the sixth side 118 in the second light emitting unit 1042 and the fourth intersection A4 connecting the seventh side 119 and the eighth side 120 in the second light emitting unit 1042 and the first direction is greater than or equal to the fifth angle θ5 between the side wall 125 and the first direction, wherein the fourth intersection A4 and the above-mentioned Figure 5 The sixth intersection point A6 in the same position is the same intersection point, and the second angle θ2 is the same as the above Figure 5 The fourth angle θ4 in the figure is the same angle at the same position. Further, the fifth angle θ5 can be controlled to satisfy 45°≤θ5≤75°, so as to minimize the edge light emitted by the second light emitting unit 1042 from being absorbed by the first sub-shading unit 1081, thereby ensuring the display effect of the second display area 102.

[0048] Optional, Fig. 9 A schematic diagram of the structure of another display panel provided by an embodiment of the present invention is shown in FIG. Fig. 9 As shown, the first sub-light-shielding unit 1081 includes a first sub-light-shielding unit 1083 and a first sub-light-shielding unit 1084, and the first sub-light-shielding unit 1083 is located on the side of the first sub-light-shielding unit 1084 close to the first display area 101; along the second direction (such as the X direction in the figure), the width of the first sub-light-shielding unit 1083 is smaller than the width of the first sub-light-shielding unit 1084; the second sub-light-shielding unit 1082 includes a second sub-light-shielding unit 1085 and a second sub-light-shielding unit 1086, and the second sub-light-shielding unit 1085 is located on the side of the second sub-light-shielding unit 1086 close to the first display area 101; along the second direction, the width of the second sub-light-shielding unit 1085 is greater than the width of the first sub-light-shielding unit 1084; wherein the second direction is parallel to the plane where the substrate 103 is located and intersects with the first direction.

[0049] In order to further control the display effect of the second display area 102, along the second direction, the second direction is parallel to the plane where the base substrate 103 is located. Since the display panel 100 has a certain thickness, when the display panel 100 is bent along the side away from the light emitting direction, the bending degree of the light emitting surface side of the display panel 100 is significantly greater than the bending degree of the side of the base substrate 103. At this time, the base substrate 103 and the light emitting unit 104 located on one side of the base substrate 103 extend in a direction perpendicular to the first direction as an example. As the curvature of the second display area 102 increases, the widths of the first sub-shading unit 1081 and the second sub-shading unit 1082 can be adjusted to ensure that the light emitting ranges of each second light emitting unit 1042 are as similar as possible. The first sub-light-shielding unit 1081 includes a first sub-light-shielding unit 1083 and a first sub-light-shielding unit 1084. Along the second direction, the width of the first sub-light-shielding unit 1083 is smaller than the width of the first sub-light-shielding unit 1084, and the width of the first sub-light-shielding unit 1081 gradually increases; the second sub-light-shielding unit 1082 includes a second sub-light-shielding unit 1085 and a second sub-light-shielding unit 1086. The width of the second sub-light-shielding unit 1085 is larger than the width of the first sub-light-shielding unit 1084, and the width of the second sub-light-shielding unit 1082 gradually decreases. The spacing between the second sub-shading units 1082 limits the light emitting range of the corresponding second light emitting unit 1042. Therefore, as the curvature of the second display area 102 increases, the spacing between adjacent first sub-shading units 1081 and the spacing between the second sub-shading units 1082 are controlled to ensure that in the second display area 102, the second angle θ2 in different second shading units 108 is as consistent as possible, and then makes it and the first angle θ1 in the first shading unit 107 satisfy θ1-θ2≤5°, so as to achieve display uniformity of the display panel 100.

[0050] Optional, Fig.10 A schematic diagram of the structure of another display panel provided by an embodiment of the present invention is shown in FIG. Fig.10 As shown, along the first direction, the first light-shielding unit 107 includes a third sub-light-shielding unit 1071 located on the side of the color filter layer 105 close to the base substrate 103 and a fourth sub-light-shielding unit 1072 located on the side of the color filter layer 105 away from the base substrate 103; along the first direction, the third sub-light-shielding unit 1071 and the fourth sub-light-shielding unit 1072 at least partially overlap.

[0051] Among them, the first shading unit 107 located in the first display area 101 is set to a double-layer structure, the third sub-shading unit 1071 is located on the side of the color filter layer 105 close to the base substrate 103, and the fourth sub-shading unit 1072 is located on the side of the color filter layer 105 away from the base substrate 103. By setting the third sub-shading unit 1071 and the fourth sub-shading unit 1072 to adjust the light output angle of the first display area 101, in the first direction, the third sub-shading unit 1071 and the fourth sub-shading unit 1072 at least partially overlap, and the coverage area of ​​the fourth sub-shading unit 1072 is greater than the coverage area of ​​the third sub-shading unit 1071. For example, Figure 8 As shown, the projection area of ​​the fourth sub-shading unit 1072 completely covers the projection area of ​​the third sub-shading unit 1071. By making the third shading unit of the first shading unit 107 and the first shading unit 107 of the second shading unit 108 in the same layer, the fourth sub-shading unit 1072 of the first shading unit 107 and the second sub-shading unit 1082 of the second shading unit 108 in the same layer, and the first sub-shading unit 1081 and the third sub-shading unit 1071 are both located between adjacent color filter units 1051, the existence of the shading unit can be ensured, the leveling effect of the color filter unit 1051 can be ensured, and the uniformity of the light emitted through the color filter unit 1051 can be achieved.

Since the first display area 101 is a plane area, the width W1 of the third sub-shading unit 1073 and the width W2 of the third sub-shading unit 1074 are reasonably controlled to meet The width W3 of the fourth shading unit 1075 and the width W4 of the fourth shading unit 1076 satisfy This allows the adjacent third sub-shading units 1071 and the adjacent fourth sub-shading units 1072 to be as consistent as possible, thereby allowing the first angle θ1 in the first shading unit 107 to be consistent in the first display area 101 , thereby ensuring the display effect of the first display area 101 .

[0055] Among them, since the coverage area of ​​the fourth sub-shading unit 1072 in the first display area 101 is larger than the coverage area of ​​the third sub-shading unit 1071, and the coverage area of ​​the first sub-shading unit 1081 in the second display area 102 is larger than the coverage area of ​​the second sub-shading unit 1082, the maximum width of the fourth sub-shading unit 1072 in the first display area 101 can be reasonably controlled to be larger than the maximum width of the first sub-shading unit 1081 in the second display area 102, so as to ensure that the light emitted through the light output unit 104 is consistently reflected by the internal metal wiring in the display panel 100, thereby ensuring the display effect of the display panel 100.

[0056] Optional, Fig.11 A schematic diagram of the structure of another display panel provided by an embodiment of the present invention is shown in FIG.

[0057] The third sub-shading unit 1071 located in the first display area 101 and the first sub-shading unit 1081 in the second display area 102 are both located in the same layer and are both located between adjacent color filter units 1051. The width W5 of the first sub-shading unit 1081 and the width W6 of the third sub-shading unit 1071 can be adjusted to meet Along the second direction, the widths of the first sub-shading unit 1081 and the third sub-shading unit 1071 are as similar as possible, and along the thickness direction of the display panel 100, the extended heights are also the same, thereby improving the leveling effect of the color filter layer 105 during the preparation process, ensuring the thickness uniformity of the color filter layer 105, and further ensuring the display effect of the display panel 100.
