[0045] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0046] Based on the content recorded in the background technology of this application, refer to Figure 1 , Figure 1 As a schematic diagram of the effect after the transfer of light-emitting units in the prior art, usually, the transfer of the light-emitting unit 12 is to transfer the light-emitting unit 12 to the substrate 11 by means of a stamp grab. Considering problems such as the hardness of the stamp head, inaccurate alignment angle during the transfer process, or inconsistent pad heights on the substrate 11, the light-emitting unit 12 will be in an inclined state after the transfer of the light-emitting unit 12, and the inclined directions of multiple light-emitting units 12 are the same under the same transfer process, that is, they are all inclined towards one direction; then the light emitted by the light-emitting unit 12 will also be emitted in the inclined direction, resulting in a serious color cast problem on the display panel, thereby seriously affecting the display effect of the display panel.

[0047] Based on this, a new type of display panel is provided in the embodiments of this application. Refer to Figure 2 , Figure 2Schematic diagram of the light emitted by a light-emitting unit according to an embodiment of the present invention. Taking two light-emitting units that emit light of the same color as an example, the two light-emitting units of the same color are arranged along the first direction X, and the first direction X is the direction from the center of the first light-emitting unit 02 to the center of the second light-emitting unit 02. Adjust the inclination states of the two light-emitting units 02 of the same color so that the extension directions of the orthographic projections of the two light-emitting units 02 in the first direction X intersect. That is to say, the light-emitting surfaces of the two light-emitting units 02 are inclined in different directions. As Figure 2 shown, the light emitted by the first light-emitting unit 02 can make up for the area where the second light-emitting unit 02 fails to emit light. That is, the light emitted by the light-emitting units of the same color can be complementary in different directions, thereby ensuring uniform light emission of the display panel from multiple angles and improving the display effect of the display panel.

[0048] It should be noted that the light-emitting units of the same color refer to light-emitting units that emit light of the same color. For example, light-emitting units that all emit red light, green light, or blue light.

[0049] In order to make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0050] Refer to Figure 3 , Figure 3 which is a top view schematic diagram of a display panel provided by an embodiment of the present invention.

[0051] The display panel includes:

[0052] a substrate 01, and a light-emitting unit 02 located on one side of the substrate 01.

[0053] The display panel includes a plurality of first display areas 03. The light-emitting unit 02 includes a first light-emitting unit 02a. The first display area 03 includes at least two of the first light-emitting units 02a. The two first light-emitting units 02a are arranged along the first direction X, and the orthographic projections of the two first light-emitting units 02a along the first direction X intersect.

[0054] Specifically, the light-emitting unit 02 includes, but is not limited to, light-emitting units such as Mini-LED light-emitting units or Micro-LED light-emitting units; refer to Figure 4 , Figure 4 which is a schematic diagram of the direction of the first direction in an embodiment of the present invention. The first direction X is the direction from the center of the first first light-emitting unit 02a to the center of the second first light-emitting unit 02a. Refer to Figure 5 , Figure 5Schematic diagram of the arrangement of light-emitting units for discovering technical problems provided by an embodiment of the present invention. If the inclination directions and inclination angles of the first first light-emitting unit 02a and the second first light-emitting unit 02a are the same, the front projections of the two first light-emitting units 02a in the first direction X coincide. The light emitted by the first first light-emitting unit 02a and the second first light-emitting unit 02a will also be emitted in the inclined direction. At this time, the light emitted by the two first light-emitting units 02a cannot be complementary in different directions. Therefore, in the embodiment of the present application, the two first light-emitting units 02a are arranged according to the rule that their front projections along the first direction X cross, as Figure 2 shown. Adjust the inclination states of the two same-color light-emitting units 02 so that the extension directions of the front projections of the two light-emitting units 02 in the first direction X cross. That is to say, the light-emitting surfaces of the two light-emitting units 02 are inclined in different directions. The light emitted by the first light-emitting unit 02 can make up for the area where the second light-emitting unit 02 fails to emit light. That is, the light emitted by the same-color light-emitting units can be complementary in different directions, thereby ensuring uniform light emission of the display panel from multiple angles and improving the display effect of the display panel.

[0055] It should be noted that the shape of the first display area 03 shown is only illustrated by way of example, and its specific shape will be further described in the following embodiments of the present invention. Also, two first light-emitting units 02a are taken as an example in one first display area 03, and the arrangement manner of the two first light-emitting units 02a in one first display area 03 is also only illustrated by way of example, and is not limited in the embodiments of the present invention.

[0056] Optionally, in another embodiment of the present invention, refer to Figure 6 , Figure 6 Schematic cross-sectional view of a display panel provided by an embodiment of the present invention.

[0057] The substrate 01 includes: a substrate 011, and an array layer 012 located between the substrate 011 and the light-emitting unit 02.

[0058] Specifically, the array layer 012 is also called a TFT (Thin Film Transistor) layer, and is used to control the working state of the light-emitting unit 02.

[0059] Such as Figure 6As shown, the array layer 012 includes a plurality of thin film transistors 013; wherein, each thin film transistor 013 includes an active layer 013a, a gate 013b, a source 013c, and a drain 013d. The array layer 012 further includes a gate insulating layer 014 disposed between the active layer 013a and the gate 013b, an interlayer insulating layer 015 disposed between the gate 013b and the source 013c and the drain 013d, a passivation layer 016 disposed on a side of the source 13c and the drain 13d facing away from the interlayer insulating layer 015, and a planarization layer 017 disposed on a side of the passivation layer 016 facing away from the interlayer insulating layer 015. Wherein, a registration electrode 018 is disposed on a side of the planarization layer 017 facing away from the substrate 011, and the registration electrode 018 is correspondingly connected to an electrode of the light emitting unit 02, and the registration electrode 018 is electrically connected to a corresponding electrode terminal of the thin film transistor 013.

[0060] It should be noted that the source 13c and the drain 13d are located on the same layer.

[0061] It should be noted that in the embodiments of the present invention, the thin film transistor 013 can be a P-type thin film transistor or an N-type thin film transistor. In the embodiments of the present invention, the P-type thin film transistor is taken as an example for illustration.

[0062] Its specific connection manner is as Figure 6 shown. By etching the planarization layer 017 and the passivation layer 016 to form through holes, the corresponding electrode terminals of the thin film transistor 013 are exposed, so that the registration electrode 018 and the corresponding electrode terminals of the thin film transistor 013 are in contact and electrically connected.

[0063] Optionally, as Figure 6 shown, the substrate 01 may further include a buffer layer 019 located between the substrate 011 and the array layer 012.

[0064] The buffer layer 019 includes, but is not limited to, an inorganic material layer or an organic material layer. Among them, the materials of the inorganic material layer include, but are not limited to, silicon oxide, silicon nitride, silicon oxynitride, aluminum oxide, aluminum nitride, etc., and the materials of the organic material layer include, but are not limited to, acrylic or PI, etc.

[0065] The light emitting surface of the light emitting unit 02 includes opposite first end A1 and second end A2. Taking a rectangular light emitting unit as an example for illustration, the first end A1 and the second end A2 are respectively located at opposite ends in the extending direction of the long side of the rectangle.

[0066] The distance G1 between the first end A1 and the substrate 01 is less than the distance G2 between the second end A2 and the substrate 01.

[0067] Specifically, as Figure 6 shown, the distance G1 between the first end A1 and the substrate 01 refers to the distance between the first end A1 of the light-emitting surface of the light-emitting unit 02 and the first surface of the substrate 01, and the distance between the second end A2 and the substrate 01 refers to the distance between the second end A2 of the light-emitting surface of the light-emitting unit 02 and the first surface of the substrate 01, where the first surface of the substrate 01 is the surface of the substrate 01 facing the light-emitting unit 02.

[0068] At this time, the light-emitting surface of the light-emitting unit 02 and the plane where the substrate 01 is located are in a non-parallel state, which means that the position and attitude of the light-emitting unit 02 on the substrate 01 are in an inclined state. Based on the position and attitude of the light-emitting unit 02, the same-color light-emitting units are arranged according to the rule of the positive projection intersection along the first direction X. As Figure 2 shown, the light emitted by the first light-emitting unit 02 can make up for the area where the second light-emitting unit 02 fails to emit light, that is, the light emitted by the same-color light-emitting units can be complementary in different directions, thereby ensuring uniform light emission of the display panel from multiple angles and improving the display effect of the display panel.

[0069] Optionally, in another embodiment of the present invention, refer to Figure 7 , Figure 7 which is a schematic structural diagram of a light-emitting unit provided by an embodiment of the present invention.

[0070] The light-emitting unit 02 includes a first electrode 021 and a second electrode 022. The first electrode 021 corresponds to the first end A1, and the second electrode 022 corresponds to the second end A2. Taking a rectangular light-emitting unit as an example, the first end A1 and the second end A2 are respectively located at opposite ends in the extending direction of the long side of the rectangle, and the first electrode 021 and the second electrode 022 are also respectively located at opposite ends of the long side of the rectangle, and the first electrode 021 and the first end A1 are located at the same end, and the second electrode 022 and the second end A2 are located at the same end.

[0071] The maximum distance G3 between the first electrode 021 and the light-emitting surface is less than the maximum distance G4 between the second electrode 022 and the light-emitting surface.

[0072] Specifically, the light-emitting unit 02 further includes: a substrate 023; an N-type semiconductor layer 024, an MQW (Multiple Quantum Well) layer 025, and a P-type semiconductor layer 026 sequentially located on the substrate 023.

[0073] Among them, the first electrode 021 is located on the N-type semiconductor layer 024, and the second electrode 022 is located on the P-type semiconductor layer 026. That is to say, in the embodiment of the present application, the first electrode 021 is the N electrode of the light-emitting unit 02, and the second electrode 022 is the P electrode of the light-emitting unit 02.

[0074] It should be noted that the material of the substrate 023 includes but is not limited to sapphire, aluminum nitride, silicon nitride, gallium nitride single crystal material, etc.

[0075] The N-type semiconductor layer 024 includes but is not limited to an N-type gallium nitride semiconductor layer, and the P-type semiconductor layer 026 includes but is not limited to a P-type gallium nitride semiconductor layer.

[0076] Among them, the maximum distance G3 between the first electrode 021 and the light-emitting surface refers to the distance between the first surface of the first electrode 021 and the light-emitting surface, and the maximum distance G4 between the second electrode 022 and the light-emitting surface refers to the distance between the first surface of the second electrode 022 and the light-emitting surface; the first surface of the first electrode 021 refers to the surface of the first electrode 021 on the side away from the light-emitting surface, and the first surface of the second electrode 022 refers to the surface of the second electrode 022 on the side away from the light-emitting surface.

[0077] As Figure 7 It can be seen from the light-emitting unit structure shown that the first surfaces of the first electrode 021 and the second electrode 022 are not on the same horizontal plane. After the light-emitting unit 02 is transferred, the position and attitude of the light-emitting unit 02 on the substrate 01 may be in an inclined state, that is, the light-emitting surface of the light-emitting unit 02 is not parallel to the plane where the substrate 01 is located. In the present application, based on the inclined light-emitting unit, the same-color light-emitting units are arranged according to the rule that the orthographic projections along the first direction intersect, as Figure 2 shown. The light emitted by the first light-emitting unit 02 can make up for the area where the second light-emitting unit 02 fails to emit light, that is, the light emitted by the same-color light-emitting units can be complementary in different directions, thereby ensuring uniform light emission from multiple angles of the display panel and improving the display effect of the display panel.

[0078] Optionally, in another embodiment of the present invention, referring to Figure 8 , Figure 8 is a cross-sectional schematic diagram of another display panel provided by the embodiment of the present invention.

[0079] The display panel further includes a first alignment electrode 04 and a second alignment electrode 05. The first alignment electrode 04 corresponds to the first end A1, and the second alignment electrode 05 corresponds to the second end A2.

[0080] The maximum distance G5 between the first alignment electrode 04 and the substrate 01 is less than the maximum distance G6 between the second alignment electrode 05 and the substrate 01.

[0081] Specifically, as Figure 7 and Figure 8 shown, the first alignment electrode 04 and the second alignment electrode 05 are located on one side of the substrate 01 and between the substrate 01 and the light-emitting unit 02. After the light-emitting unit 02 is transferred, the first alignment electrode 04 is welded to the first electrode 021 of the light-emitting unit 02, and the second alignment electrode 05 is welded to the second electrode 022 of the light-emitting unit 02. At this time, the first alignment electrode 04 corresponds to the first end A1 of the light-emitting surface of the light-emitting unit 02, and the second alignment electrode 05 corresponds to the second end A2 of the light-emitting surface of the light-emitting unit 02.

[0082] Among them, the maximum distance G5 between the first alignment electrode 04 and the substrate 01 refers to the distance between the first surface of the first alignment electrode 04 and the first surface of the substrate 01, and the maximum distance G6 between the second alignment electrode 05 and the substrate 01 refers to the distance between the first surface of the second alignment electrode 05 and the first surface of the substrate 01; the first surface of the first alignment electrode 04 refers to the surface of the first alignment electrode 04 facing away from the substrate 01, the first surface of the second alignment electrode 05 refers to the surface of the second alignment electrode 05 facing away from the substrate 01, and the first surface of the substrate 01 refers to the surface of the substrate 01 facing the light-emitting unit 02.

[0083] As Figure 7 and Figure 8 shown by the light-emitting unit structure and the relative position relationship with the substrate, the first surfaces of the first electrode 021 and the second electrode 022 are not on the same horizontal plane, and / or the thicknesses of the first alignment electrode 04 and the second alignment electrode 05 are different, which may cause the position and attitude of the light-emitting unit 02 on the substrate 01 to be inclined after the light-emitting unit 02 is transferred to the substrate 01, that is, the light-emitting surface of the light-emitting unit 02 is not parallel to the plane of the substrate 01. Therefore, in this application, based on the inclined light-emitting unit 02, the inclination directions of the same-color light-emitting units are coordinated during the transfer process of the light-emitting unit 02, and they are arranged according to the rule that the positive projections of the same-color light-emitting units along the first direction X intersect, as Figure 2 shown, the light emitted by the first light-emitting unit 02 can make up for the area where the second light-emitting unit 02 fails to emit light, that is, the light emitted by the same-color light-emitting units can be complementary in different directions, thereby ensuring uniform light emission from multiple angles of the display panel and improving the display effect of the display panel.

[0084] Optionally, in another embodiment of the present invention, referring toFigure 9 , Figure 9 This is a schematic layout diagram of the light-emitting units in the first display area provided by an embodiment of the present invention.

[0085] The shape of the first display area 03 is an N-sided polygon or a circle, where N≥3.

[0086] The first display area 03 includes M first light-emitting units 02a, where 2≤M≤N and M is a positive integer. The M first light-emitting units 02a are arranged along the sides of the N-sided polygon or the tangents of the circle in a first rotation direction K1, and in the first rotation direction K1, the first end A1 of the first first light-emitting unit 02a among two adjacent first light-emitting units 02a is adjacent to the second end A2 of the second first light-emitting unit 02a.

[0087] Specifically, as Figure 9 shown, assuming that the shape of the first display area 03 is a triangle, the first display area 03 includes three first light-emitting units 02a. The arrangement directions of the first first light-emitting unit 02a and the second first light-emitting unit 02a are X1, the arrangement directions of the second first light-emitting unit 02a and the third first light-emitting unit 02a are X2, and the arrangement directions of the third first light-emitting unit 02a and the first light-emitting unit 02a are X3. The three first light-emitting units 02a are arranged along the three sides of the triangle in a first rotation direction K1. The first end A1 of the first first light-emitting unit 02a is adjacent to the second end A2 of the second first light-emitting unit 02a, the first end A1 of the second first light-emitting unit 02a is adjacent to the second end A2 of the third first light-emitting unit 02a, and the first end A1 of the third first light-emitting unit 02a is adjacent to the second end A2 of the first first light-emitting unit 02a.

[0088] Referring to Figure 10 , Figure 10 This is a schematic projection diagram of two first light-emitting units in the X1 arrangement direction provided by an embodiment of the present invention. The light-emitting surfaces of the two first light-emitting units 02a are inclined in different directions. The light emitted by the first first light-emitting unit 02a can make up for the area where the second first light-emitting unit 02a fails to emit light, that is, the light emitted by the same-color light-emitting units can be complementary in different directions, thereby ensuring uniform light emission from multiple angles of the display panel and improving the display effect of the display panel.. Figure 9

[0089] Similarly, referring to Figure 11 , Figure 11 ​Another schematic diagram of the arrangement of the light-emitting units in the first display area provided by the embodiment of the present invention. The shape of the first display area 03 is a quadrilateral, and the quadrilateral can be a rectangle, a square, a parallelogram or other quadrilaterals. The first display area 03 includes four first light-emitting units 02a, and the four first light-emitting units 02a are arranged along the sides of the quadrilateral in the first rotation direction K1. The first end A1 of the first first light-emitting unit 02a is adjacent to the second end A2 of the second first light-emitting unit 02a, the first end A1 of the second first light-emitting unit 02a is adjacent to the second end A2 of the third first light-emitting unit 02a, the first end A1 of the third first light-emitting unit 02a is adjacent to the second end A2 of the fourth first light-emitting unit 02a, and the first end A1 of the fourth first light-emitting unit 02a is adjacent to the second end A2 of the first first light-emitting unit 02a. Arranged according to Figure 10 the arrangement rules shown, the positive projections of adjacent two light-emitting units along the first direction X intersect, so that the light emitted by the same-color light-emitting units can be complementary in different directions, thereby ensuring uniform light emission from multiple angles of the display panel and improving the display effect of the display panel.

[0090] Similarly, referring to Figure 12 , Figure 12 Another schematic diagram of the arrangement of the light-emitting units in the first display area provided by the embodiment of the present invention. The shape of the first display area 03 is a hexagon; referring to Figure 13 , Figure 13 Another schematic diagram of the arrangement of the light-emitting units in the first display area provided by the embodiment of the present invention. The shape of the first display area 03 is an octagon; referring to Figure 14 , Figure 14 Another schematic diagram of the arrangement of the light-emitting units in the first display area provided by the embodiment of the present invention. The shape of the first display area 03 is a circle.

[0091] It should be noted that when the shape of the first display area 03 is a circle, M first light-emitting units 02a are arranged along the tangent of the circle in the first rotation direction K1, and the first end A1 of the first of the adjacent two first light-emitting units 02a in the first rotation direction K1 is adjacent to the second end A2 of the second first light-emitting unit 02a.

[0092] That is to say, in the embodiment of the present application, the shape of the first display area 03 can be flexibly defined based on the number of light-emitting units to be arranged in each first display area 03. That is to say, the shapes of multiple first display areas 03 in the display panel can be the same or different; or based on the set shape of the first display area 03, the number of light-emitting units to be arranged in the first display area 03 can be flexibly determined; thereby improving the flexibility of the arrangement of the light-emitting units in the display area of the display panel.

[0093] It should be noted that the first rotation direction K1 can be a clockwise rotation direction or a counterclockwise rotation direction, which is not limited in the embodiments of the present application. In the drawings, only the counterclockwise direction is taken as an example for illustration.

[0094] Optionally, based on Figure 12 the first display area 03 shown, when transferring the first light-emitting unit 02a, first transfer the first first light-emitting unit 02a, and then transfer one first light-emitting unit 02a every 60° rotation, so as to achieve Figure 12 the arrangement of multiple first light-emitting units 02a in the first display area 03 shown, and the first end A1 of the first of the adjacent two first light-emitting units 02a is adjacent to the second end A2 of the second first light-emitting unit 02a; similarly, the above transfer method can also be used for other N-sided polygons or circles to transfer the light-emitting units.

[0095] That is to say, in the transfer process of the light-emitting unit 02, the above transfer method can coordinate the inclination directions of the same-color light-emitting units, and can arrange the same-color light-emitting units according to the rule that the positive projections along the first direction X intersect, as Figure 2 shown. The light emitted by the first light-emitting unit 02 can make up for the area where the second light-emitting unit 02 fails to emit light, that is, the light emitted by the same-color light-emitting units can be complementary in different directions, thereby ensuring uniform light emission from multiple angles of the display panel and improving the display effect of the display panel.

[0096] Optionally, in another embodiment of the present invention, as Figure 14 shown,

[0097] the distance between adjacent two first light-emitting units 02a is equal.

[0098] Specifically, taking the shape of the first display area as a circle as an example for illustration, the distance between adjacent two first light-emitting units 02a refers to the distance between the first end A1 of the first of the adjacent two first light-emitting units 02a and the second end A2 of the second first light-emitting unit 02a.

[0099] For example, the distance between the first end A1 of the first first light-emitting unit 02a and the second end A2 of the second first light-emitting unit 02a is Q1, and the distance between the first end A1 of the second first light-emitting unit 02a and the second end A2 of the third first light-emitting unit 02a is Q2, then Q1 = Q2.

[0100] In an embodiment of the present invention, the distance between two adjacent first light-emitting units 02a is set to be equal, that is, multiple first light-emitting units 02a are regularly arranged in the first display area 03, so as to improve the light-emitting uniformity of the first light-emitting units 02a in each first display area 03.

[0101] Optionally, in another embodiment of the present invention, referring to Figure 15 , Figure 15 is a schematic diagram of the arrangement of light-emitting units in another first display area provided by an embodiment of the present invention.

[0102] The light-emitting unit further includes: a second light-emitting unit 02b; the light-emitting color of the second light-emitting unit 02b is different from the light-emitting color of the first light-emitting unit 02a.

[0103] The first display area 03 includes the second light-emitting units 02b, and the second light-emitting units 02b are arranged along the sides of the N-sided polygon or the tangents of the circle in a second rotation direction K2, and in the second rotation direction K2, the first end A1 of the first second light-emitting unit 02b among two adjacent second light-emitting units 02b is adjacent to the second end A2 of the second second light-emitting unit 02b.

[0104] Specifically, the first light-emitting unit 02a may be a light-emitting unit that emits red light, and the second light-emitting unit 02b may be a light-emitting unit that emits green light.

[0105] As Figure 15 shown, the shape of the first display area 03 is a hexagon, the first display area 03 includes six second light-emitting units 02b, in the second rotation direction K2, the first end A1 of the first second light-emitting unit 02b among two adjacent second light-emitting units 02b is adjacent to the second end A2 of the second second light-emitting unit 02b, and is arranged according to the Figure 15 shown arrangement rule, the positive projection of two adjacent same-color light-emitting units along the first direction X intersects, and the light emitted by the first second light-emitting unit 02b can make up for the area where the second second light-emitting unit 02b fails to emit light, that is, the light emitted by the same-color light-emitting units can be complementary in different directions, thereby ensuring the uniform light emission of the display panel from multiple angles, and thus improving the display effect of the display panel.

[0106] Assume that the shape of the first display area 03 is triangular, and the first display area 03 includes three second light-emitting units 02b. The three second light-emitting units 02b are arranged along the three sides of the triangle in the second rotation direction K2. The first end A1 of the first second light-emitting unit 02b is adjacent to the second end A2 of the second second light-emitting unit 02b. The first end A1 of the second second light-emitting unit 02b is adjacent to the second end A2 of the third second light-emitting unit 02b. The first end A1 of the third second light-emitting unit 02b is adjacent to the second end A2 of the first second light-emitting unit 02b.

[0107] Assume that the shape of the first display area 03 is quadrilateral, and the quadrilateral can be a rectangle or a square or a parallelogram or other quadrilaterals. The first display area 03 includes four second light-emitting units 02b. The four second light-emitting units 02b are arranged along the sides of the quadrilateral in the second rotation direction K2. The first end A1 of the first second light-emitting unit 02b is adjacent to the second end A2 of the second second light-emitting unit 02b. The first end A1 of the second second light-emitting unit 02b is adjacent to the second end A2 of the third second light-emitting unit 02b. The first end A1 of the third second light-emitting unit 02b is adjacent to the second end A2 of the fourth second light-emitting unit 02b. The first end A1 of the fourth second light-emitting unit 02b is adjacent to the second end A2 of the first second light-emitting unit 02b.

[0108] Optionally, refer to Figure 16 , Figure 16 which is another layout schematic diagram of the light-emitting units in the first display area provided by the embodiment of the present invention. The shape of the first display area 03 is circular.

[0109] It should be noted that when the shape of the first display area 03 is circular, multiple second light-emitting units 02b are arranged along the tangent of the circle in the second rotation direction K2, and the first end A1 of the first second light-emitting unit 02b among two adjacent second light-emitting units in the second rotation direction K2 is adjacent to the second end A2 of the second second light-emitting unit 02b.

[0110] It should be noted that the second rotation direction K2 can be a clockwise rotation direction or a counterclockwise rotation direction, which is not limited in the embodiments of the present application. Only the clockwise direction is taken as an example for illustration in the figure.

[0111] It should be noted that the first rotation direction K1 and the second rotation direction K2 may be the same or different. For example, both the first rotation direction K1 and the second rotation direction K2 are clockwise rotation directions or counterclockwise rotation directions at the same time; or the first rotation direction K1 is a clockwise rotation direction and the second rotation direction K2 is a counterclockwise rotation direction; or the first rotation direction K1 is a counterclockwise rotation direction and the second rotation direction K2 is a clockwise rotation direction.

[0112] Optionally, in another embodiment of the present invention, as Figure 16 shown,

[0113] the distance between two adjacent second light-emitting units 02b is equal.

[0114] Specifically, taking the shape of the first display area 03 as a circle as an example, the distance between two adjacent second light-emitting units 02b refers to the distance between the first end A1 of the first second light-emitting unit 02b and the second end A2 of the second second light-emitting unit 02b among two adjacent second light-emitting units 02b.

[0115] For example, the distance between the first end A1 of the first second light-emitting unit 02b and the second end A2 of the second second light-emitting unit 02b is W1, and the distance between the first end A1 of the second second light-emitting unit 02b and the second end A2 of the third second light-emitting unit 02b is W2, then W1 = W2.

[0116] In the embodiment of the present invention, setting the distance between two adjacent second light-emitting units 02b to be equal, that is, arranging multiple second light-emitting units 02b regularly in the first display area 03 can improve the light-emitting uniformity of the second light-emitting units 02b in each first display area 03.

[0117] Optionally, in another embodiment of the present invention, referring to Figure 17 , Figure 17 is a schematic diagram of the arrangement of light-emitting units in another first display area provided by the embodiment of the present invention.

[0118] The second light-emitting unit 02b is located between two adjacent first light-emitting units 02a.

[0119] Specifically, taking the shape of the first display area 03 as a hexagon as an example, as Figure 17 shown, the first light-emitting unit 02a and the second light-emitting unit 02b are arranged alternately. Similarly, in the first display area 03 with other N-sided shapes and circles except hexagons, the first light-emitting unit 02a and the second light-emitting unit 02b can also be arranged according to the Figure 17 shown arrangement method, which will not be elaborated here one by one.

[0120] It should be noted that the numbers of the first light-emitting unit 02a and the second light-emitting unit 02b may be the same or different. Based on Figure 21 the shown first display area, the number of the first light-emitting units 02a is three, and the number of the second light-emitting units 02b is also three. One second light-emitting unit 02b is arranged between every two adjacent first light-emitting units 02a; when the shape of the first display area 03 is triangular, the number of the first light-emitting units 02a is two, and the number of the second light-emitting units 02b is one. At this time, the numbers of the first light-emitting unit 02a and the second light-emitting unit 02b are different; or based on Figure 21 the shown first display area 03 being hexagonal, second light-emitting units 02b may also be arranged between some adjacent first light-emitting units 02a, and not arranged between some adjacent first light-emitting units 02a. That is to say, in this application, the numbers of the first light-emitting unit 02a and the second light-emitting unit 02b can be reasonably and flexibly set based on the specific arrangement mode.

[0121] However, based on the arrangement mode in which the first light-emitting unit 02a and the second light-emitting unit 02b are arranged alternately, the light-emitting uniformity of the first light-emitting unit 02a and the second light-emitting unit 02b in each first display area 03 can be improved.

[0122] Optionally, in another embodiment of the present invention, referring to Figure 18 , Figure 18 is a schematic diagram of the arrangement of the light-emitting units in the first display area provided by the embodiment of the present invention.

[0123] The second light-emitting unit 02b is located on the side of the first light-emitting unit 02a close to the geometric center of the N-sided polygon or the circle.

[0124] Specifically, taking the shape of the first display area 03 being octagonal as an example for illustration, in the area surrounded after the first light-emitting units 02a are arranged, the second light-emitting units 02b are reasonably arranged inside the area surrounded by the first light-emitting units 02a. That is to say, the second light-emitting units 02b are closer to the geometric center of the octagon than the first light-emitting units 02a.

[0125] It should be noted that the numbers of the first light-emitting unit 02a and the second light-emitting unit 02b are not limited, and may be equal or unequal.

[0126] Similarly, in the first display areas 03 of other N-sided polygons and circles except the octagon, the first light-emitting units 02a and the second light-emitting units 02b can also be arranged according to the Figure 18 shown arrangement mode, which will not be elaborated here one by one.

[0127] Taking the shape of the first display area 03 as a circle as an example for illustration, in the area surrounded after the arrangement of the first light-emitting units 02a is completed, the second light-emitting units 02b are reasonably arranged inside the area surrounded by the first light-emitting units 02a. That is to say, the second light-emitting units 02b are closer to the geometric center of the circle compared to the first light-emitting units 02b, that is, the second light-emitting units 02b are closer to the center of the circle compared to the first light-emitting units 02a.

[0128] Optionally, in another embodiment of the present invention, referring to Figure 19 , Figure 19 is another schematic diagram of the arrangement of the light-emitting units in the first display area provided by the embodiment of the present invention.

[0129] The second light-emitting units 02b are correspondingly arranged with the gaps between two adjacent first light-emitting units 02a.

[0130] Specifically, taking the shape of the first display area 03 as a hexagon as an example for illustration, since the second light-emitting units 02b are arranged inside the area surrounded by the first light-emitting units 02a and the arrangement area is reduced, the second light-emitting units 02b can be correspondingly arranged with the gaps between two adjacent first light-emitting units 02a based on the number of the second light-emitting units 02b to be arranged. That is to say, a second light-emitting unit 02b is placed at the position opposite to the gap between two adjacent first light-emitting units 02a, so as to arrange more second light-emitting units 02b in the limited arrangement area. Similarly, in the first display area 03 with other N-sided shapes and circles except hexagons, the first light-emitting units 02a and the second light-emitting units 02b can also be arranged according to the Figure 19 shown arrangement method, which will not be elaborated here one by one.

[0131] Taking the shape of the first display area 03 as a circle as an example for illustration, the second light-emitting units 02b are arranged inside the area surrounded by the first light-emitting units 02a, and the second light-emitting units 02b are correspondingly arranged with the gaps between two adjacent first light-emitting units 02a.

[0132] Optionally, in another embodiment of the present invention, referring to Figure 20 , Figure 20 is another schematic diagram of the arrangement of the light-emitting units in the first display area provided by the embodiment of the present invention.

[0133] The light-emitting units further include: third light-emitting units 02c; the light-emitting colors of the first light-emitting units 02a, the second light-emitting units 02b, and the third light-emitting units 02c are different from each other.

[0134] The first display area 03 includes the third light-emitting unit 02c. The third light-emitting units 02c are arranged in a third rotation direction K3 along the sides of the N-sided polygon or the tangents of the circle. The first end A1 of the first third light-emitting unit 02c among two adjacent third light-emitting units 02c in the third rotation direction K3 is adjacent to the second end A2 of the second third light-emitting unit 02c.

[0135] Specifically, the first light-emitting unit 02a may be a light-emitting unit that emits red light, the second light-emitting unit 02b may be a light-emitting unit that emits green light, and the third light-emitting unit 02c may be a light-emitting unit that emits blue light.

[0136] As Figure 20 shown, the shape of the first display area 03 is a hexagon. The first display area 03 includes six third light-emitting units 02c. The first end A1 of the first third light-emitting unit 02c among two adjacent third light-emitting units 02c in the third rotation direction K3 is adjacent to the second end A2 of the second third light-emitting unit 02c. Arranged according to the Figure 20 arrangement rule shown, the positive projections of two adjacent light-emitting units of the same color along the first direction X intersect. The light emitted by the first third light-emitting unit 02c can compensate for the area where the second third light-emitting unit 02c fails to emit light. That is, the light emitted by the light-emitting units of the same color can be complementary in different directions, thereby ensuring uniform light emission from multiple angles of the display panel and improving the display effect of the display panel.

[0137] Assume that the shape of the first display area 03 is a triangle. The first display area 03 includes three third light-emitting units 02c. The three third light-emitting units 02c are arranged in a third rotation direction K3 along the three sides of the triangle. The first end A1 of the first third light-emitting unit 02c is adjacent to the second end A2 of the second third light-emitting unit 02c. The first end A1 of the second third light-emitting unit 02c is adjacent to the second end A2 of the third third light-emitting unit 02c. The first end A1 of the third third light-emitting unit 02c is adjacent to the second end A2 of the first third light-emitting unit 02c.

[0138] Assume that the shape of the first display area 03 is a quadrilateral, which can be a rectangle, a square, a parallelogram or other quadrilaterals. The first display area 03 includes four third light-emitting units 02c, and the four third light-emitting units 02c are arranged along the sides of the quadrilateral in a third rotation direction K3. The first end A1 of the first third light-emitting unit 02c is adjacent to the second end A2 of the second third light-emitting unit 02c, the first end A1 of the second third light-emitting unit 02c is adjacent to the second end A2 of the third third light-emitting unit 02c, the first end A1 of the third third light-emitting unit 02c is adjacent to the second end A2 of the fourth third light-emitting unit 02c, and the first end A1 of the fourth third light-emitting unit 02c is adjacent to the second end A2 of the first third light-emitting unit 02c.

[0139] Optionally, referring to Figure 21 , Figure 21 FIG. is a schematic diagram of the arrangement of the light-emitting units in the first display area provided by another embodiment of the present invention, and the shape of the first display area 03 is a circle.

[0140] It should be noted that when the shape of the first display area 03 is a circle, the plurality of third light-emitting units 02c are arranged along the tangent of the circle in a third rotation direction K3, and the first end A1 of the first of the two adjacent third light-emitting units 02c in the third rotation direction K3 is adjacent to the second end A2 of the second third light-emitting unit 02c.

[0141] It should be noted that the third rotation direction K3 can be a clockwise rotation direction or a counterclockwise rotation direction, which is not limited in the embodiments of the present application, and only the counterclockwise direction is taken as an example for illustration in the drawings.

[0142] It should be noted that the first rotation direction K1, the second rotation direction K2, and the third rotation direction K3 can be the same or different, which is not limited in the embodiments of the present invention.

[0143] Optionally, in another embodiment of the present invention, as Figure 21 shown,

[0144] The distance between two adjacent third light-emitting units 02c is equal.

[0145] Specifically, taking the shape of the first display area 03 as a circle as an example for illustration, the distance between two adjacent third light-emitting units 02c refers to the distance between the first end A1 of the first of the two adjacent third light-emitting units 02c and the second end A2 of the second third light-emitting unit 02c.

[0146] For example, the distance between the first end A1 of the first third light-emitting unit 02c and the second end A2 of the second third light-emitting unit 02c is E1, and the distance between the first end A1 of the second third light-emitting unit 02c and the second end A2 of the third third light-emitting unit 02c is E2, then E1 = E2.

[0147] In the embodiment of the present invention, the distances between adjacent two of the third light-emitting units 02c are set to be equal, that is, the multiple third light-emitting units 02c are regularly arranged in the first display area 03, which can improve the light-emitting uniformity of the third light-emitting units 02c in each first display area 03.

[0148] Optionally, in another embodiment of the present invention, refer to Figure 22 , Figure 22 which is another schematic diagram of the arrangement of the light-emitting units in the first display area provided by the embodiment of the present invention.

[0149] The third light-emitting unit 02c is located on the side of the second light-emitting unit 02b close to the geometric center of the N-sided shape or the circle.

[0150] Specifically, taking the shape of the first display area 03 as an octagon as an example, in the area surrounded after the arrangement of the first light-emitting units 02a, the second light-emitting units 02b are reasonably arranged inside the area surrounded by the first light-emitting units 02a. In the area surrounded after the arrangement of the second light-emitting units 02b, the third light-emitting units 02c are reasonably arranged inside the area surrounded by the second light-emitting units 02b. That is to say, the second light-emitting units 02b are closer to the geometric center of the octagon than the first light-emitting units 02a, and the third light-emitting units 02c are closer to the geometric center of the octagon than the second light-emitting units 02b.

[0151] It should be noted that the numbers of the first light-emitting unit 02a, the second light-emitting unit 02b, and the third light-emitting unit 02c are not limited and can be equal or unequal.

[0152] Similarly, in the first display areas 03 of other N-sided shapes and circles except the octagon, the first light-emitting units 02a, the second light-emitting units 02b, and the third light-emitting units 02c can also be arranged according to the Figure 22 shown arrangement method, which will not be elaborated here one by one.

[0153] Taking the shape of the first display area 03 as a circle as an example for illustration, in the area enclosed after the arrangement of the first light-emitting units 02a, the second light-emitting units 02b are reasonably arranged inside the area enclosed by the first light-emitting units 02a. In the area enclosed after the arrangement of the second light-emitting units 02b, the third light-emitting units 02c are reasonably arranged inside the area enclosed by the second light-emitting units 02b. That is to say, the second light-emitting units 02b are closer to the geometric center of the circle compared to the first light-emitting units 02a, and the third light-emitting units 02c are closer to the geometric center of the circle compared to the second light-emitting units 02b. That is, the second light-emitting units 02b are closer to the center of the circle compared to the first light-emitting units 02a, and the third light-emitting units 02c are closer to the center of the circle compared to the second light-emitting units 02b.

[0154] Optionally, in another embodiment of the present invention, referring to Figure 23 , Figure 23 is another schematic diagram of the arrangement of the light-emitting units in the first display area provided by the embodiment of the present invention.

[0155] The third light-emitting unit 02c is correspondingly arranged with the gaps between two adjacent second light-emitting units 02b.

[0156] Specifically, taking the shape of the first display area 03 as a hexagon as an example for illustration, since the third light-emitting units 02c are arranged inside the area enclosed by the second light-emitting units 02b, the arrangement area is reduced. Then, the gaps between the third light-emitting units 02c and two adjacent second light-emitting units 02b can be correspondingly set based on the number of the third light-emitting units 02c to be arranged. That is to say, a third light-emitting unit 02c is placed at the position opposite to the gap between two adjacent second light-emitting units 02b, so as to arrange more third light-emitting units 02c in the limited arrangement area. Similarly, in the first display area 03 with other N-sided shapes and circles except hexagons, the first light-emitting units 02a, the second light-emitting units 02b, and the third light-emitting units 02c can also be arranged according to the Figure 23 shown arrangement method, which will not be elaborated here one by one.

[0157] Optionally, in another embodiment of the present invention, referring to Figure 24 , Figure 24 is another schematic diagram of the arrangement of the light-emitting units in the first display area provided by the embodiment of the present invention.

[0158] The third light-emitting unit 02c is located on the side of the first light-emitting unit 02a and the second light-emitting unit 02b close to the geometric center of the N-sided shape or the circle.

[0159] Specifically, taking the shape of the first display area 03 as a hexagon as an example for illustration, the first light-emitting units 02a and the second light-emitting units 02b are alternately arranged along the sides of the hexagon, and the third light-emitting units 02c are arranged inside the enclosed area. That is to say, the distances from the first light-emitting units 02a and the second light-emitting units 02b to the geometric center of the hexagon are equal, while the third light-emitting units 02c are closer to the geometric center of the hexagon than the first light-emitting units 02a and / or the second light-emitting units 02b.

[0160] Similarly, in the first display areas 03 with other N-sided polygons and circles except for the hexagon, the first light-emitting units 02a, the second light-emitting units 02b, and the third light-emitting units 02c can also be arranged according to the Figure 24 arrangement method shown, which will not be elaborated one by one here.

[0161] Taking the shape of the first display area 03 as a circle as an example for illustration, the first light-emitting units 02a and the second light-emitting units 02b are alternately arranged along the tangents of the circle, and the third light-emitting units 02c are arranged inside the enclosed area. That is to say, the distances from the first light-emitting units 02a and the second light-emitting units 02b to the geometric center of the circle are equal, while the third light-emitting units 02c are closer to the geometric center of the circle than the first light-emitting units 02a and / or the second light-emitting units 02b, that is, the third light-emitting units 02c are closer to the center of the circle than the first light-emitting units 02a and / or the second light-emitting units 02b.

[0162] Optionally, in another embodiment of the present invention, referring to Figure 25 , Figure 25 is a schematic diagram of the arrangement of the light-emitting units in the first display area provided by the embodiment of the present invention.

[0163] The first light-emitting units 02a, the second light-emitting units 02b, and the third light-emitting units 02c are arranged in sequence along the sides of the N-sided polygon or the tangents of the circle in the fourth rotation direction K4.

[0164] Specifically, taking the shape of the first display area 03 as a hexagon as an example for illustration, the first light-emitting units 02a, the second light-emitting units 02b, and the third light-emitting units 02c are alternately arranged in sequence along the sides of the hexagon. Similarly, in the first display areas 03 with other N-sided polygons and circles except for the hexagon, the first light-emitting units 02a, the second light-emitting units 02b, and the third light-emitting units 02c can also be arranged according to the Figure 25 arrangement method shown, which will not be elaborated one by one here..

[0176] Specifically, taking the shape of the first display area 03 as a circle as an example, the first display area 03 further includes an edge area CC surrounding the light-transmitting area BB. The edge area CC is used to arrange the first light-emitting unit 02a, the second light-emitting unit 02b, and the third light-emitting unit 02c.

[0181] Wherein, λ1 > λ2.

[0182] Wherein, the size of the first light-emitting unit 02a is larger than the size of the second light-emitting unit 02b.

[0183] Specifically, the first light-emitting unit 02a can be a light-emitting unit for emitting red light, and the second light-emitting unit 02b can be a light-emitting unit for emitting green light.
