[0029] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the following will be combined with the accompanying drawings for the embodiments of the present application to make a clear and complete description of the technical solutions in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0030] Various modifications and changes can be made to the present application without departing from the spirit and scope of the present application. It is understood that such modifications and changes are intended to fall within the scope of the present application. It should be noted that the embodiments provided by the present application can be combined with each other without contradiction.

[0031] The terms used in the embodiments of the present application are only for the purpose of describing particular embodiments and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0032] The embodiments of the present application provide a display panel, the shape of the connecting portion between adjacent light emitting devices on the display layer is designed, so that the connecting portion increases the light shielding of one of the adjacent light emitting devices and reduces the light shielding of the other at a large viewing angle, thereby optimizing the large viewing angle luminance decay of different color light emitting devices, optimizing the color locus, and improving the large viewing angle color deviation problem.

[0033] FIG. 1 is a schematic view of a display panel according to an embodiment of the present application, FIG. 2 is a schematic view of a cross section of the display panel along the line A-A' in FIG. 1, and FIG. 3 is a schematic view of a partial enlargement of the display panel at a first light emitting device and a second light emitting device in FIG. 1.

[0034] Referring to FIGS. 1 and 2, the display panel includes a substrate 00 and a display layer 10 on one side of the substrate 00, the display layer 10 including a plurality of light emitting devices 1. The light emitting devices 1 include first light emitting devices 11, second light emitting devices 12, and third light emitting devices 13 having different light emitting colors. The first light emitting devices 11, the second light emitting devices 12, and the third light emitting devices 13 are each one of a red light emitting device, a green light emitting device, and a blue light emitting device, and are each different from one another. The display layer 10 further includes a pixel definition layer 14 between adjacent light emitting devices 1. The light emitting devices 1 include a first electrode 1a, a light emitting layer 1b, and a second electrode 1c stacked. Optionally, the first electrode 1a is an anode and the second electrode 1c is a cathode. The light emitting layer 1b can be different in the light emitting devices 1 of different colors. At least one functional layer 20 is provided on a side of the display layer 10 distal from the substrate 00, the functional layer 20 including a plurality of connection portions 2. As shown in the plan view of FIG. 1, the connection portions 2 are in orthographic projection between adjacent light emitting devices 1.

[0035] A driving layer 30 is provided between the display layer 10 and the substrate 00, the driving layer 30 including a pixel circuit for driving the light emitting devices 1 to emit light. An encapsulation layer 40 is further provided on the display layer 10, the encapsulation layer 40 optionally including at least one organic encapsulation layer and at least one inorganic encapsulation layer, the encapsulation layer 40 for encapsulating the light emitting devices 1.

[0036] The plurality of connection portions 2 includes at least one first connection portion 21 in orthographic projection between the first light emitting devices 11 and the second light emitting devices 12. The first light emitting devices 11 and the second light emitting devices 12 have a first virtual center line 51 therebetween, the first light emitting devices 11 and the second light emitting devices 12 being equidistant from the first virtual center line 51. As shown in FIG. 3, the first light emitting devices 11 have first straight sides 111, the second light emitting devices 12 have second straight sides 121, and the first virtual center line 51 is parallel to the first straight sides 111 when the first straight sides 111 and the second straight sides 121 are parallel to each other, the first straight sides 111 being equidistant from the first virtual center line 51 as the second straight sides 121.

[0037] As shown in FIG. 3, the first connecting part 21 comprises a first region Z1 and a second region Z2, the first region Z1 is located on the side of the first virtual center line 51 close to the first light emitting device 11, and the second region Z2 is located on the side of the first virtual center line 51 close to the second light emitting device 12. The total area of the first region Z1 is S1, and the total area of the second region Z2 is S2, S1>S2. That is, the first virtual center line 51 divides the first connecting part 21 into two parts. FIG. 3 shows the first connecting part 21 as a curve, and the second region Z2 divided by the first virtual center line 51 comprises two unconnected sub-regions, and the total area S2 is the sum of the areas of the two sub-regions. In other words, the first virtual center line 51 does not equally divide the area of the first connecting part 21, and the first connecting part 21 deviates from the first virtual center line 51, so that at least part of the first connecting part 21 is closer to the first light emitting device 11.

[0038] As the connecting part 2 is located between adjacent light emitting devices 1, as shown in FIG. 1, a plurality of connecting parts 2 are connected to form a grid, that is, the first connecting part 21 is connected to the connecting part 2 at other positions. Since the area of the first connecting part 21 located on the two sides of the first virtual center line 51 is not equal, the problem of how to define the boundary of the first connecting part 21 needs to be considered. As shown in FIG. 1, the connecting part 2 comprises a first type of connecting part 2a extending along a third direction a and a second type of connecting part 2b extending along a fourth direction b, and the third direction a and the fourth direction b intersect. Alternatively, the third direction a and the fourth direction b are perpendicular to each other. Taking the first connecting part 21 located between the first light emitting device 11 and the second light emitting device 12 as an example, the first connecting part 21 shown in FIG. 1 extends along the fourth direction b, and the first virtual center line 51 shown in FIG. 1 extends along the fourth direction b. The first connecting part 21 shown in FIG. 1 belongs to the second type of connecting part 2b, and is connected to four first type of connecting parts 2a extending along the third direction a. The first connecting part 21 shown in FIG. 1 has one contact position with each of the four first type of connecting parts 2a, that is, a total of four contact positions. The boundary of the first connecting part 21 is determined according to the two contact positions with the smallest distance on both sides along the fourth direction b. As shown in FIG. 1, the distance between the contact position W1 and the contact position W2 along the fourth direction b is the smallest, the first virtual line segment X1 extending along the third direction a passes through the contact position W1, and the second virtual line segment X2 extending along the third direction a passes through the contact position W2, and the part between the first virtual line segment X1 and the second virtual line segment X2 is the first connecting part 21.

[0039] As can be seen in the partial sectional view of Fig. 2, the first connecting portion 21 at this position is closer to the first light emitting device 11. A virtual connecting portion 2' is also shown in Fig. 2 by a dashed line, which has the same distance to the first light emitting device 11 as to the second light emitting device 12. When the connecting portion between the first light emitting device 11 and the second light emitting device 12 is the virtual connecting portion 2', the first light rays (dashed arrows in Fig. 2) emitted by the first light emitting device 11 can be emitted in a large angle direction; when the connecting portion between the first light emitting device 11 and the second light emitting device 12 is the first connecting portion 21, the second light rays (solid arrows in Fig. 2) emitted by the first light emitting device 11 can be emitted in a large angle direction. When a user views the electronic device, there is a direct view and a large angle view, the direct view direction is the direction e shown in Fig. 2 which is perpendicular to the plane of the display panel, and the large angle view direction has an angle with the direction e, for example, the angle is equal to 60°. It can be seen that the angle between the second light rays and the direction e is smaller than the angle between the first light rays and the direction e, when the virtual connecting portion 2' is provided, both the first light rays and the second light rays can be emitted in a large angle direction, and when the first connecting portion 21 is provided, the second light rays can be emitted in a large angle direction, and the first light rays are blocked by the first connecting portion 21 and cannot be emitted, which indicates that the first connecting portion 21 increases the large angle light emission blocking of the first light emitting device 11, and correspondingly, the large angle light emission blocking of the second light emitting device 12 by the first connecting portion 21 is reduced.

[0040] The display panel provided by the embodiment of the present application designs the first connecting portion 21 between the adjacent first light emitting device 11 and the second light emitting device 12. The first connecting portion 21 is arranged to have a larger area on the side of the first virtual middle line 51 closer to the first light emitting device 11. In this way, the first connecting portion 21 increases the large angle light emission blocking of the first light emitting device 11, and can also appropriately reduce the large angle light emission blocking of the second light emitting device 12. Or when the local position of the first connecting portion 21 is widened to increase the area of the first region Z1 without changing the area of the second region Z2, the first connecting portion 21 increases the large angle light emission blocking of the first light emitting device 11 without changing the large angle light emission blocking of the second light emitting device 12. The embodiment of the present application can optimize the large angle luminance decay of the first light emitting device 11 and the second light emitting device 12, improve the large angle color deviation, and improve the large angle visual effect.

[0041] As shown in FIG. 1, the display panel includes a plurality of first virtual quadrilaterals 01 and a plurality of second virtual quadrilaterals 02; four first light emitting devices 11 are respectively located at four vertex positions of the first virtual quadrilateral 01, one second light emitting device 12 or one third light emitting device 13 is located in the first virtual quadrilateral 01; two second light emitting devices 12 are located at two opposite vertex positions on the second virtual quadrilateral 02, two third light emitting devices 13 are located at the other two vertex positions on the second virtual quadrilateral 02, and one first light emitting device 11 is located in the second virtual quadrilateral 02. Among them, the first virtual quadrilateral 01 can be any one of a rectangle, a trapezoid, a rhombus, and an irregular quadrilateral. The second virtual quadrilateral 02 can also be any one of a rectangle, a trapezoid, a rhombus, and an irregular quadrilateral. The first light emitting device 11, the second light emitting device 12, and the third light emitting device 13 are respectively one of a red light emitting device, a green light emitting device, and a blue light emitting device. The light emitting device arrangement mode provided by the embodiment of the application can improve the aperture ratio of the display panel.

[0042] In the embodiment of the application, the shape of the light emitting device can be a rectangle, a circle, or a rhombus, or a deformation based on the above shapes. The shape of the light emitting device is the graphic shape of its light emitting area. In one embodiment, the first light emitting device 11 is a hexagon, and the second light emitting device 12 and the third light emitting device 13 are rectangles.

[0043] In some embodiments, the first connecting portion 21 includes opposite second and third edges; the first connecting portion 21 is located between two adjacent light emitting devices 1 with different light emitting colors, and the second and third edges are adjacent to one light emitting device 1, respectively, and the extension directions of the second and third edges are the same as the extension direction of the first connecting portion 21. Among them, at least one of the second and third edges is a curve or a broken line, the curve includes an arc, a wavy line, etc., and the broken line includes a broken line with one corner or a multi-segment broken line. That is, at least one of the second and third edges is a non-straight line. Taking the first connecting portion 21 shown in FIG. 3 as an example, it can be seen that the opposite second edge B2 and the third edge B3 of the first connecting portion 21 are both curves. In the embodiment of the application, at least one of the two opposite edges of the first connecting portion 21 is set as a curve or a broken line, so that at least part of the first connecting portion 21 deviates from the first virtual center line 51, at least part of the first connecting portion 21 is closer to the first light emitting device 11, thereby increasing the large-angle light shielding of the first connecting portion 21 to the first light emitting device 11, and also appropriately reducing the large-angle light shielding of the first connecting portion 21 to the second light emitting device 12, thereby optimizing the large-view-angle luminance decay of the first light emitting device 11 and the second light emitting device 12, improving the large-view-angle color deviation, and improving the large-view-angle visual effect.

[0044] In some embodiments, at least one of the second edge B2 and the third edge B3 of the first connecting portion 21 is a curve, and FIG. 3 schematically shows that both the second edge B2 and the third edge B3 are curves.

[0045] In another embodiment, FIG. 4 schematically shows another display panel provided by an embodiment of the present application. As shown in FIG. 4, a first connecting portion 21 is arranged between adjacent first light emitting devices 11 and second light emitting devices 12, the first connecting portion 21 has opposite second edge B2 and third edge B3, the second edge B2 is adjacent to the second light emitting device 12, the third edge B3 is adjacent to the first light emitting device 11, the second edge B2 is a straight line, and the third edge B3 is a curve, the areas of two regions of the first connecting portion 21 located on both sides of the first virtual middle line 51 are different, and the area of the region of the first connecting portion 21 located on the side of the first virtual middle line 51 close to the first light emitting device 11 is larger. When the embodiment of FIG. 4 is applied, the first connecting portion 21 can be used to increase the shielding of large-angle light emission of the first light emitting device 11 and reduce the shielding of large-angle light emission of the second light emitting device 12 by adjusting the distance between the second edge B2 and the first virtual middle line 51, thereby optimizing the large viewing angle luminance decay of the first light emitting device 11 and the second light emitting device 12. Alternatively, the first connecting portion 21 can be used to increase the shielding of large-angle light emission of the first light emitting device 11 without changing the shielding of large-angle light emission of the second light emitting device 12, thereby optimizing the large viewing angle luminance decay of the first light emitting device 11. In addition, the first connecting portion 21 shown in FIG. 4 extends in the fourth direction b, and the first virtual line segment X1 and the second virtual line segment X2 defining the boundary of the first connecting portion 21 are shown in FIG. 4 according to the related description in the embodiment of FIG. 1.

[0046] In another embodiment, the second edge B2 of the first connecting portion 21 is adjacent to the second light emitting device 12, the third edge B3 is adjacent to the first light emitting device 11, the second edge B2 is a curve, and the third edge B3 is a straight line, so that the areas of two regions of the first connecting portion 21 located on both sides of the first virtual middle line 51 are different, which is not schematically shown in the figure.

[0047] In another embodiment, the second edge B2 of the first connecting portion 21 is adjacent to the second light emitting device 12, the third edge B3 is adjacent to the first light emitting device 11, one of the second edge B2 and the third edge B3 is a polyline, and the other is a straight line, so that the areas of two regions of the first connecting portion 21 located on both sides of the first virtual middle line 51 are different, which is not schematically shown in the figure.

[0048] In some other embodiments, FIG. 5 schematically shows another display panel provided by an embodiment of the present application. As shown in FIG. 5, the second edge B2 of the first connecting portion 21 is adjacent to the second light emitting device 12, the third edge B3 is adjacent to the first light emitting device 11, and both the second edge B2 and the third edge B3 are polylines.

[0049] In some embodiments, Fig. 6 is a schematic view of another display panel according to an embodiment of the present application. As shown in Fig. 6, the second edge B2 of the first connecting part 21 is adjacent to the second light emitting device 12, and the third edge B3 of the first connecting part 21 is adjacent to the first light emitting device 11. The second edge B2 and the third edge B3 are both broken lines with one corner. In this way, the shape of the first connecting part 21 is relatively simple. In the first connecting part 21, the areas of the two regions on both sides of the first virtual middle line 51 are different, and the area of the region on the side of the first virtual middle line 51 close to the first light emitting device 11 is larger. In addition, the first virtual line segment X1 and the second virtual line segment X2 defining the boundary of the first connecting part 21 are indicated according to the related description in the embodiment of Fig. 1.

[0050] In some embodiments, as shown in Fig. 5 or Fig. 6, the shapes of the second edge B2 and the third edge B3 opposite to each other on the first connecting part 21 are the same. In this way, the shape of the first connecting part 21 is relatively simple, and the areas of the two regions on both sides of the first virtual middle line 51 are also easier to control. Therefore, the large viewing angle luminance decay of the light emitting device is easier to control.

[0051] In some embodiments, as shown in Fig. 3, the distance between the second edge B2 and the third edge B3 in the direction perpendicular to the extension direction of the first virtual middle line 51 is a constant value d. In this embodiment, the first connecting part 21 has a relatively uniform width at different positions in the extension direction of the first connecting part 21. When the first connecting part 21 has a conductive property, the resistance value of the first connecting part 21 is relatively uniform, and the electrical property of the whole functional layer is stable.

[0052] In some embodiments, Fig. 7 is a schematic view of another display panel according to an embodiment of the present application. Fig. 7 only shows the local position of one first light emitting device 11 and one second light emitting device 12. The second edge B2 of the first connecting part 21 is adjacent to the second light emitting device 12, and the third edge B3 of the first connecting part 21 is adjacent to the first light emitting device 11. As shown in Fig. 7, the first connecting part 21 includes a first sub-part 211 and a second sub-part 212. In the direction f perpendicular to the extension direction of the first virtual middle line 51, the distance between the second edge B2 and the third edge B3 in the first sub-part 211 is d1, the distance between the second edge B2 and the third edge B3 in the second sub-part 212 is d2, and d1>d2. In this embodiment, the first sub-part 211 and the second sub-part 212 have different widths. In other words, the width of the local position of the first connecting part 21 can be increased to make the local position of the first connecting part 21 closer to the first light emitting device 11, and thus the area of the region on the side of the first virtual middle line 51 close to the first light emitting device 11 in the first connecting part 21 is increased.

[0053] In some embodiments, the second edge B2 and the third edge B3 in the first connecting portion 21 are both curved lines, and the width of the first connecting portion 21 at a local position is increased to increase the area of the region in the first connecting portion 21 located on the side of the first virtual center line 51 close to the first light emitting device 11.

[0054] In some embodiments, FIG. 8 is a schematic diagram of another display panel provided by an embodiment of the present application. As shown in FIG. 8, the second edge B2 of the first connecting portion 21 is adjacent to the second light emitting device 12, and the third edge B3 of the first connecting portion 21 is adjacent to the first light emitting device 11. The second edge B2 has a first point W3, and the center O2 of the second light emitting device 12 and the first point W3 have a first line X3 therebetween. The straight line on which the first line X3 is located is perpendicular to the first virtual center line 51. The length of the portion of the first line X3 located between the second edge B2 and the second light emitting device 12 is L1. The third edge B3 has a second point W4, and the center O1 of the first light emitting device 11 and the second point W4 have a second line X4 therebetween. The straight line on which the second line X4 is located is perpendicular to the first virtual center line 51. The length of the portion of the second line X4 located between the third edge B3 and the first light emitting device 11 is L2. L1>L2. The center of the light emitting device is the geometric center of the light emitting region of the light emitting device. This embodiment at least at the position close to the center of the first light emitting device 11 and the position close to the center of the second light emitting device 11, the distance between the first connecting portion 21 and the first light emitting device 11 is smaller, which can increase the regulation range of the large-angle light shielding of the first light emitting device 11, has higher light shielding regulation freedom, and is more conducive to meeting the design requirements, thereby optimizing the large-view-angle luminance decay of the first light emitting device 11 and the second light emitting device 12.

[0055] In some embodiments, as shown in FIG. 8, in a local position of the display panel in the first direction i, the first light emitting device 11 is located between two adjacent second light emitting devices 12, and the first direction i is parallel to the plane on which the substrate is located. FIG. 8 is a top view of the display panel, and the first connecting portion 21 and its orthographic projection on the display layer 10 coincide. As can be seen from FIG. 8, the two orthographic projections of the first connecting portion 21 on the display layer 10 are located on both sides of the first light emitting device 11 in the first direction i, and the two first connecting portions 21 are axially symmetric or rotationally symmetric. Such arrangement not only facilitates the design of the shape of the first connecting portion 21 in the entire display area, but also enables the two first connecting portions 21 on both sides of the first light emitting device 11 to have substantially the same degree of regulation of the large-angle light shielding of the light emitting device, which is conducive to ensuring the uniformity of the light emitting efficiency of the same color light emitting device, thereby ensuring the uniformity of the brightness of the entire display area.

[0056] In combination with FIG. 1, part of the first light emitting device 11 is located between two second light emitting devices 12 in the third direction a, and part of the first light emitting device 11 is located between two second light emitting devices 12 in the fourth direction b. Optionally, the two first connecting portions 21 located on both sides of the first light emitting device 11 in the third direction a are axisymmetric or rotationally symmetric, and / or the two first connecting portions 21 located on both sides of the first light emitting device 11 in the fourth direction b are axisymmetric or rotationally symmetric.

[0057] In some embodiments, FIG. 9 is another schematic diagram of a display panel provided by an embodiment of the present application. As shown in FIG. 9, the display panel includes a first virtual quadrilateral 01, four first light emitting devices 11 are respectively located at the four vertexes of the first virtual quadrilateral 01, and at least part of the first virtual quadrilateral 01 is provided with a second light emitting device 12; in the first virtual quadrilateral 01, a first connecting portion 21 is arranged between the second light emitting device 12 and N of the four first light emitting devices 11, N is an integer, 1≤N≤3. In FIG. 9, N=1 is taken as an example, and the opposite two edges of the first connecting portion 21 are curved. In this embodiment, the connecting portion 2 between some adjacent first light emitting devices 11 and second light emitting devices 12 is of a conventional shape, for example, the opposite two edges of the connecting portion 2 are straight lines; the first connecting portion 21 is arranged between some adjacent first light emitting devices 11 and second light emitting devices 12, and the first connecting portion 21 is used to adjust the large-angle light shielding of the light emitting devices on both sides. The above arrangement has little change on the connecting portion 2 in the whole display area, the electrical performance of the multiple connecting portions 2 as a whole has little change, and the large viewing angle luminance decay of most first light emitting devices 11 and most second light emitting devices 12 is optimized as a whole, which plays a role in improving the large viewing angle color shift.

[0058] In some embodiments, as shown in FIG. 9, the first connecting part 21 is arranged between the partial second light emitting device 12 and the first light emitting device 11 in the first quadrant with the partial second light emitting device 12 as the origin; the first connecting part 21 is arranged between the partial second light emitting device 12 and the first light emitting device 11 in the second quadrant with the partial second light emitting device 12 as the origin; the first connecting part 21 is arranged between the partial second light emitting device 12 and the first light emitting device 11 in the third quadrant with the partial second light emitting device 12 as the origin; and the first connecting part 21 is arranged between the partial second light emitting device 12 and the first light emitting device 11 in the fourth quadrant with the partial second light emitting device 12 as the origin. For the second light emitting device 12 at different positions on the display panel, the second light emitting device 12 is taken as the origin when the four quadrants are demarcated, and the extension directions of the horizontal coordinates of the coordinate systems at different positions are the same, and the extension directions of the vertical coordinates of the coordinate systems at different positions are the same, i.e., the positive directions of the x coordinates are the same, the negative directions of the x coordinates are the same, the positive directions of the y coordinates are the same, and the negative directions of the y coordinates are the same. The connecting part 2 between some adjacent first light emitting devices 11 and second light emitting devices 12 is of a regular shape in this embodiment, and the first connecting part 21 is arranged between other adjacent first light emitting devices 11 and second light emitting devices 12, and the first connecting part 21 is used to adjust the large-angle light shielding of the light emitting devices on both sides. The arrangement as above changes the connecting part 2 in the whole display area little, and the electrical performance of the plurality of connecting parts 2 changes little as a whole. The first connecting part 21 between the second light emitting device 12 and the first light emitting device 11 in the first quadrant of the coordinate system where the second light emitting device 12 is located is a first connecting part, which can adjust the large-angle light shielding of the first light emitting device 11 in a certain direction and the large-angle light shielding of the second light emitting device 12 in a certain direction. Four kinds of first connecting parts 21 are arranged in the display panel in this embodiment, and each kind of first connecting part 21 adjusts the large-angle light shielding of a kind of first light emitting device 11 in a direction and adjusts the large-angle light shielding of a kind of second light emitting device 12 in a direction. The four kinds of first connecting parts 21 can be used to adjust the light shielding of the four kinds of first light emitting devices 11 in four directions and adjust the light shielding of the four kinds of second light emitting devices 12 in four directions. From the whole display panel, the large-angle brightness decay of the plurality of first light emitting devices 11 in four directions can be optimized, the large-angle brightness decay of the plurality of second light emitting devices 12 in four directions can be optimized, and the large visual angle color deviation can be improved.

[0059] In some embodiments, FIG. 10 is a schematic view of another display panel provided by an embodiment of the present application. As shown in FIG. 10, the second light emitting device 12 includes a first side B1 which is arc-shaped, and the second light emitting device 12 corresponds to a circumscribed virtual quadrilateral 03, and the first side B1 is tangent to the circumscribed virtual quadrilateral 03; wherein the first side B1 is adjacent to the first connecting part 21. In this embodiment, the first side B1 of the second light emitting device 12 is tangent to the circumscribed virtual quadrilateral 03, and the circumscribed virtual quadrilateral 03 can be a rectangle or a rhombus. It can be considered that the first side B1 is locally shrunk relative to the circumscribed virtual quadrilateral 03, so as to increase the distance between the first side B1 and the first light emitting device 11, which is conducive to improving the lateral leakage between the first light emitting device 11 and the second light emitting device 12, and reducing the risk of device light stealing. Moreover, the area of the second light emitting device 12 is smaller than the area of the circumscribed virtual quadrilateral 03, so that the light output of the second light emitting device 12 is reduced to a certain extent, and the large-angle light output of the second light emitting device 12 is correspondingly reduced to a certain extent. The shape of the second light emitting device 12 is designed and matched with the first connecting part 21 to optimize the large-angle brightness decay of the second light emitting device 12.

[0060] In other embodiments, FIG. 11 is a schematic view of another display panel provided by an embodiment of the present application. As shown in FIG. 11, the second light emitting device 12 includes a first side B1 which is arc-shaped, and the second light emitting device 12 corresponds to a circumscribed virtual quadrilateral 03, and the first side B1 is tangent to the circumscribed virtual quadrilateral 03; the first side B1 is a side of the second light emitting device 12 far away from the first connecting part 21.

[0061] In other embodiments, the first side B1 of part of the second light emitting device 12 is adjacent to the first connecting part 21, and the first side B1 of part of the second light emitting device 12 is a side of the second light emitting device 12 far away from the first connecting part 21. This is not shown in the schematic view.

[0062] In some embodiments, FIG. 12 is a schematic view of a partial enlarged view of the first light emitting device and the third light emitting device in FIG. 1. In combination with FIG. 1 and FIG. 12, the connecting portion 2 includes at least one second connecting portion 22, and the second connecting portion 22 is located between the adjacent first light emitting device 11 and the third light emitting device 13 in the orthographic projection of the display layer 10. The adjacent first light emitting device 11 and the third light emitting device 13 have a second virtual center line 52, and the minimum distance of the second virtual center line 52 from the first light emitting device 11 is equal to the minimum distance of the second virtual center line 52 from the third light emitting device 13. As shown in FIG. 12, the second connecting portion 22 includes a third region Z3 and a fourth region Z4, the third region Z3 is located on one side of the second virtual center line 52 close to the first light emitting device 11, and the fourth region Z4 is located on the other side of the second virtual center line 52 close to the third light emitting device 13, the total area of the third region Z3 is S3, and the total area of the fourth region Z4 is S4, wherein S3 > S4. That is, the second virtual center line 52 divides the second connecting portion 22 into two parts, and FIG. 12 schematically shows the second connecting portion 22 as a curve, and the fourth region Z4 divided by the second virtual center line 52 includes two unconnected sub-regions, and the total area S4 is the sum of the areas of the two sub-regions. In other words, the second virtual center line 52 does not equally divide the area of the second connecting portion 22, and the second connecting portion 22 deviates from the second virtual center line 52, so that at least part of the area of the second connecting portion 22 is closer to the first light emitting device 11, thereby increasing the shielding of the large-angle light emission of the first light emitting device 11. The second connecting portion 22 can be connected with other connecting portions 2, and the boundary of the second connecting portion 22 can be defined in the same way as the first connecting portion 21, which will not be described here.

[0063] In this embodiment, the second connecting portion 22 between the adjacent first light emitting device 11 and the third light emitting device 13 is designed. The first light emitting device 11 and the third light emitting device 13 have a second virtual center line 52, and the area of the second connecting portion 22 located on one side of the second virtual center line 52 close to the first light emitting device 11 is larger. Thus, the second connecting portion 22 increases the shielding of the large-angle light emission of the first light emitting device 11 and reduces the shielding of the large-angle light emission of the third light emitting device 13, thereby optimizing the large-view-angle luminance decay of the first light emitting device 11 and the third light emitting device 13, improving the large-view-angle color deviation, and improving the large-view-angle visual effect.

[0064] In FIG. 12, the second connecting portion 22 includes two opposite edges, a fourth edge B4 and a fifth edge B5, and the fourth edge B4 and the fifth edge B5 are both curves. In other embodiments, at least one of the fourth edge B4 and the fifth edge B5 is a curve or a broken line.

[0065] In some embodiments, the shape of the second connecting portion 22 is the same as the shape of the first connecting portion 21. Such a design makes the design of the plurality of connecting portions 2 relatively simple.

[0066] In some embodiments, as shown in the partial view of the display panel in FIG. 8, in the second direction j, the first light emitting device 11 is located between two adjacent third light emitting devices 13, and the second direction j is parallel to the plane on which the substrate lies. The two second connecting portions 22 are located on both sides of the first light emitting device 11 in the second direction j in the orthographic projection of the display layer 10, and the two second connecting portions 22 are axially symmetric or rotationally symmetric. Such an arrangement not only facilitates the design of the shape of the second connecting portion 22 in the entire display area, but also enables the two second connecting portions 22 on both sides of the first light emitting device 11 to have substantially the same degree of shielding control over the large-angle light emission of the light emitting device, which is conducive to ensuring the uniformity of the light emission efficiency of the same color light emitting device and thus ensuring the uniformity of the brightness of the entire display area.

[0067] In combination with FIG. 1, some first light emitting devices 11 are located between two third light emitting devices 13 in the fourth direction b, and some first light emitting devices 11 are located between two third light emitting devices 13 in the third direction a. Optionally, the two second connecting portions 22 located on both sides of the first light emitting device 11 in the third direction a are axially symmetric or rotationally symmetric, and / or the two second connecting portions 22 located on both sides of the first light emitting device 11 in the fourth direction b are axially symmetric or rotationally symmetric.

[0068] In some embodiments, FIG. 13 is a schematic view of another display panel provided by an embodiment of the present application. As shown in FIG. 13, the display panel includes a first virtual quadrilateral 01, four first light emitting devices 11 are respectively located at the four corners of the first virtual quadrilateral 01, and at least part of the first virtual quadrilateral 01 is provided with a third light emitting device 13; in the first virtual quadrilateral 01, a second connecting portion 22 is provided between the third light emitting device 13 and M of the four first light emitting devices 11, M is an integer, 1≤M≤3. In FIG. 13, M=1 is taken as an example, and the opposite two edges of the second connecting portion 22 are taken as curves for illustration. In this embodiment, the connecting portion 2 between some adjacent first light emitting devices 11 and third light emitting devices 13 is of a conventional shape, for example, the opposite two edges of the connecting portion 2 are straight lines; the second connecting portion 22 is provided between other adjacent first light emitting devices 11 and third light emitting devices 13, and the second connecting portion 22 is used to adjust the large-angle light emission shielding of the light emitting devices on both sides. Such an arrangement has little impact on the connecting portion 2 in the entire display area, and the overall electrical performance of the multiple connecting portions 2 changes little. Moreover, from the overall perspective, the large viewing angle luminance decay of most first light emitting devices 11 and most third light emitting devices 13 is optimized, which plays a role in improving the large viewing angle color deviation.

[0069] In some embodiments, as shown in FIG. 13, the second connecting portion 22 is arranged between the partial third light emitting device 13 and the first light emitting device 11 in the first quadrant with the partial third light emitting device 13 as the origin; the second connecting portion 22 is arranged between the partial third light emitting device 13 and the first light emitting device 11 in the second quadrant with the partial third light emitting device 13 as the origin; the second connecting portion 22 is arranged between the partial third light emitting device 13 and the first light emitting device 11 in the third quadrant with the partial third light emitting device 13 as the origin; and the second connecting portion 22 is arranged between the partial third light emitting device 13 and the first light emitting device 11 in the fourth quadrant with the partial third light emitting device 13 as the origin. From the perspective of the display panel as a whole, the large-angle luminance decay of the plurality of first light emitting devices 11 in the four directions can be optimized, and the large-angle luminance decay of the plurality of third light emitting devices 13 in the four directions can also be optimized, which can improve the large-viewing-angle color deviation.

[0070] In some embodiments, the third light emitting device 13 includes a sixth side, the sixth side is arc-shaped, the third light emitting device 13 corresponds to a circumscribed virtual quadrilateral, and the sixth side is tangent to the circumscribed virtual quadrilateral corresponding to the third light emitting device 13. That is, the shape of the third light emitting device 13 can be the same as that of the second light emitting device 12 in FIG. 10. Such an arrangement can increase the distance between the third light emitting device 13 and the first light emitting device 11, which is conducive to improving the lateral leakage between the first light emitting device 11 and the third light emitting device 13 and reducing the risk of device light stealing. At the same time, the large-angle luminance decay of the third light emitting device 13 can also be optimized through the cooperation of the design of the shape of the third light emitting device 13 and the second connecting portion 22.

[0071] In some embodiments, the first light emitting device 11 is a green light emitting device, and one of the second light emitting device 12 and the third light emitting device 13 is a red light emitting device, and the other is a blue light emitting device. The embodiments of the present application can design the first connecting portion 21 and / or the second connecting portion 22 according to the differences in the large-angle luminance decay of light emitting devices of different colors, so as to adjust the large-angle light shielding of light emitting devices of different colors to different degrees, thereby improving the large-viewing-angle color deviation.

[0072] In some embodiments, the functional layer 20 includes a functional electrode, and the functional electrode includes a mesh structure formed by the cross connection of the plurality of first-type connecting portions 2a and the plurality of second-type connecting portions 2b as shown in FIG. 1.

[0073] Optionally, the functional layer 20 includes a touch layer for realizing the touch function of the display panel. The touch layer includes a touch electrode, and the touch electrode includes the plurality of first-type connecting portions 2a and the plurality of second-type connecting portions 2b.

[0074] In some embodiments, FIG. 14 is a schematic view of another display panel according to an embodiment of the present application, which shows a schematic view of a touch layer in a partial position of the display panel. As shown in FIG. 14, the touch layer 60 includes first electrode blocks 61 and second electrode blocks 62, a plurality of first electrode blocks 61 are connected to form a first touch electrode 611, and a plurality of second electrode blocks 62 are connected to form a second touch electrode 622. The extending direction of the first touch electrode 611 and the extending direction of the second touch electrode 622 are perpendicular to each other. Two adjacent second electrode blocks 62 are connected to each other by a connecting line 63, and two adjacent first electrode blocks 61 are connected to each other by a bridge line 64. The first electrode blocks 61, the second electrode blocks 62 and the connecting line 63 are located in the same layer, the first electrode blocks 61 and the bridge line 64 are located in different layers, and the first electrode blocks 61 and the bridge line 64 are connected by a via (not shown in FIG. 14) penetrating through an insulating layer. The bridge line 64 can be made of the same material as the first electrode blocks 61. Alternatively, the material of the first electrode blocks 61 includes metal, and the bridge line 64 is made of a transparent material.

[0075] The first electrode blocks 61 include a plurality of connection portions 2 as shown in FIG. 1, and the second electrode blocks 62 include a plurality of connection portions 2 as shown in FIG. 1. In the embodiment of the present application, at least part of the connection portions 2 in the touch electrode are designed, and the connection portions 2 are used to adjust the large-angle light emission of the light emitting device, to optimize the large-angle luminance decay of the light emitting device of different colors, to optimize the color locus, and to improve the large-angle color deviation.

[0076] In some embodiments, the bridge line 64 includes a first connection portion 21. In some embodiments, the bridge line 64 further includes a second connection portion 22. The connection portions 2 on the bridge line 64 are designed to optimize the large-angle luminance decay of the light emitting device and to improve the large-angle color deviation.

[0077] In some embodiments, as shown in FIG. 2, the pixel definition layer 40 has a plurality of openings K, and the light emitting device 1 is located in the openings K. In a direction parallel to the plane in which the substrate 00 is located, the distance between the edge of the first connection portion 21 and the opening K is D. In a direction perpendicular to the first virtual center line 51 and parallel to the plane in which the substrate 00 is located, the width of the first light emitting device 11 is r, and the vertical distance between the first connection portion 21 and the plane in which the light emitting device 1 is located is h. The distance between the first connection portion 21 and the light emitting surface of the light emitting device 1 is represented by h, such as the surface of the second electrode 1c.

[0078] The minimum distance of the edge of the first connecting part 21 from the opening K in a direction parallel to the plane where the substrate 00 is located is d3; d3≥(h / tan20°)-r. Thus, the maximum value of the angle between the critical light rays (such as the second light ray shown by the solid arrow in Fig. 2) emitted by the first light emitting device 11 at a large angle and the normal direction is close to 70°, and θ is about 20°, which can meet the needs of users to view at a large angle. Moreover, the distance of the edge of the first connecting part 21 from the opening K is large enough, and the first connecting part 21 can shield the light emitted by the first light emitting device 11 at a large angle to optimize the brightness decay of the first light emitting device 11 at a large angle, while ensuring that the amount of light emitted by the first light emitting device 11 in the normal direction is not affected, thereby ensuring that the brightness of the first light emitting device 11 is less affected, which is conducive to reducing power consumption.
