[0043] Optionally, the first light emitting piece 12 and the second light emitting piece 13 can be controlled to emit light by the same driving piece, or can be independently arranged, and are not limited.

[0044] In an implementation manner, the pixel structure 10 further comprises a first encapsulation adhesive layer 113, which is arranged between the first light emitting piece 12, the second light emitting piece 13 and the light shielding layer 14. The material of the first encapsulation adhesive layer 113 can be optical grade epoxy resin encapsulation adhesive with high light transmission rate, high refractive index and low viscosity.

[0048] Optionally, the pixel structure 10 further comprises a driving member for sending signals to control the brightness and color of the first light emitting member 12 and the second light emitting member 13. If the driving member is tightly integrated with the first back plate 111, the accuracy and stability of signal transmission can be ensured, thereby improving the display quality of the pixel structure 10. In addition, integrated design can also reduce electromagnetic interference and noise, further improving the display performance of the pixel structure 10.

[0049] Optionally, the size of the first light transmission area 141 and the second light transmission area 142 is the same.

[0050] The pixel structure 10 of the present application can make the corresponding display panel 100 realize multiple viewing angles and display different pictures in a limited space range.

[0051] Reference can be made to Figure 1In an embodiment, the first back plate 111 is opposite to the light shielding layer 14 in a first direction X, the first light emitting part 12 is opposite to the second light transmission area 142 in the first direction X, and the second light emitting part 13 is opposite to the first light transmission area 141 in the first direction X. The first light emitting part 12 has a first light emitting surface 121, and the second light emitting part 13 has a second light emitting surface 131. The first light emitting surface 121 has an angle with the surface of the light shielding layer 14 facing the light emitting part, and at least part of the perpendicular line of the first light emitting surface 121 passes through the first light transmission area 141. The second light emitting surface 131 has an angle with the surface of the light shielding layer 14 facing the light emitting part, and at least part of the perpendicular line of the second light emitting surface 131 passes through the second light transmission area 142. The interval between the first light emitting surface 121 and the second light emitting surface 131 in a second direction Y gradually increases in the direction close to the light shielding layer 14, and the second direction Y is the direction opposite to the first light emitting part 12 and the second light emitting part 13.

[0052] Optionally, the first light emitting part 12 comprises a first light emitting layer 122, and the first light emitting layer 122 is used for emitting light. The first light emitting layer 122 can be a MQWs light emitting layer composed of a structure of multiple alternating thin layers and barrier layers. When the first light emitting part 12 is used for emitting red light, the material of the first light emitting layer 122 can be a phosphor material, specifically, red fluorophore, PTPP, DCJTB, Tz-Gl, etc., without limitation. When the first light emitting part 12 is used for emitting green light, the material of the first light emitting layer 122 can be a phosphor material, specifically, Alaq3, TDETE, Coumarin, NpGl, etc., without limitation. When the first light emitting part 12 is used for emitting blue light, the material of the first light emitting layer 122 can be a fluorescent material, a phosphor material, etc., without limitation.

[0053] The structure and material of the second light emitting part 13, the second light emitting surface 131 and the second light emitting layer 132 can refer to the first light emitting part 12, without limitation.

[0054] The first light emitting surface 121 and the second light emitting surface 131 are in an overall flared shape. In this way, the corresponding field of view angles of the first light emitting part 12 and the second light emitting part 13 can meet the oblique viewing angle of the offset relative to the center of the display panel 100, and meet the multi-viewing angle display requirement of the display panel 100.

[0055] The first light emitting surface 121 and the second light emitting surface 131 can be in an overall flared shape. Figure 1 In an embodiment, the angle between the perpendicular line of the first light emitting surface 121 and the second direction Y is α, and the angle between the perpendicular line of the second light emitting surface 131 and the second direction Y is β, which satisfies: 30°≤α≤60°, 30°≤β≤60°.

[0056] Optionally, α can be 30°, 35°, 40°, 45°, 50°, 55°, 60°, etc., without limitation.

[0057] Optionally, β can be 30°, 35°, 40°, 45°, 50°, 55°, 60°, etc., without limitation.

[0058] When 30°≤α≤60° and 30°≤β≤60°, the user can view the picture from both sides of the display panel 100 corresponding to the pixel structure 10, thereby expanding the viewing angle of the display panel 100; when α<30° and / or β<30°, the field of view corresponding to the light transmitted through the first light transmission area 141 and / or the second light transmission area 142 is too narrow, which is not conducive to the user to view the display panel 100; when α>60° and / or β>60°, the field of view corresponding to the light transmitted through the first light transmission area 141 and / or the second light transmission area 142 tends to the middle of the display panel 100, which is easy to cause poor display effect in the middle region of the display panel 100.

[0059] For reference Figure 1 In an embodiment, the pixel structure 10 further comprises a support frame 15, which is arranged on the first back plate 111. The support frame 15 has a receiving space, and the first light emitting element 12 and the second light emitting element 13 are fixed in the receiving space.

[0060] The support frame 15 is used to protect the first light emitting element 12 and the second light emitting element 13 from external environment, and at the same time support the first light emitting element 12 and the second light emitting element 13.

[0061] The support frame 15 is composed of one or more layers of insulating material, which is used to isolate the first light emitting element 12 and the second light emitting element 13 from direct contact with external circuits and environment, thereby improving the stability and reliability of the first light emitting element 12 and the second light emitting element 13. In addition, the support frame 15 can also prevent the first light emitting element 12 and the second light emitting element 13 from being mechanically damaged or chemically corroded during manufacturing and packaging. The support frame 15 can be inorganic insulating material, organic insulating material, etc., without limitation.

[0062] A plurality of support frames 15 are arranged on the first back plate 111, or a plurality of support frames 15 can be connected in sequence.

[0063] The support frame 15 can also connect the first light emitting element 12 and the second light emitting element 13, without limitation.

[0064] The support frame 15 is arranged to support the first light emitting element 12 and the second light emitting element 13, so that the first light emitting surface 121 and the second light emitting surface 131 have an included angle with the surface of the light shielding layer 14 facing the light emitting element, thereby making the perpendicular line of the first light emitting surface 121 and the second light emitting surface 131 have an included angle with the second direction Y, thereby generating a display picture corresponding to the viewing angle.

[0065] Referring to Figure 1 In an embodiment, in a cross section parallel to the first direction X and the second direction Y, the first light-transmitting region 141 has a trapezoidal cross-sectional shape, and the size of the first light-transmitting region 141 in the second direction Y gradually increases from the direction of the first back plate 111 away from the light-blocking layer 14.

[0066] Correspondingly, in a cross section parallel to the first direction X and the second direction Y, the second light-transmitting region 142 has a trapezoidal cross-sectional shape, and the size of the second light-transmitting region 142 in the second direction Y gradually increases from the direction of the first back plate 111 away from the light-blocking layer 14.

[0067] Specifically, the first light-transmitting region 141 has an isosceles trapezoidal cross-sectional shape, and the light-blocking region 144 is formed between the first light-transmitting region 141 and the second light-transmitting region 142, and the cross-sectional shape of the light-blocking region 144 is complementary to the shapes of the first light-transmitting region 141 and the second light-transmitting region 142.

[0068] When there are multiple pixel structures 10, the multiple pixel structures 10 share the light-blocking layer 14 and the first back plate 111. The multiple first light-emitting pieces 12 and the multiple second light-emitting pieces 13 are arranged alternately in the second direction Y, and adjacent two pixel structures 10 share a first light-transmitting region 141 or a second light-transmitting region 142.

[0069] In this way, the trapezoidal first light-transmitting region 141 can be arranged correspondingly to the obliquely arranged first light-emitting surface 121, so that the corresponding display effect of the first light-emitting piece 12 is good.

[0070] Referring to Figure 3 In an embodiment, the pixel structure 10 further includes a third light-emitting piece 16, which is arranged on the side of the light-blocking layer 14 away from the first light-emitting piece 12. In the orthographic projection in the first direction X, the third light-emitting piece 16 is located between the first light-transmitting region 141 and the second light-transmitting region 142.

[0071] Optionally, the pixel structure 10 further includes a second back plate 112, a second encapsulation adhesive layer 114, and a first protective layer 115, which are sequentially stacked in the first direction X, and the surface of the second back plate 112 away from the third light-emitting piece 16 is connected with the light-blocking layer 14.

[0072] The first protective layer 115 is a transparent film layer, and the material of the first protective layer 115 can be polycarbonate (PC), polyethylene terephthalate (PET), polytetrafluoroethylene (PTFE), etc., without limitation.

[0073] Optionally, the first light emitting member 12, the second light emitting member 13 and the third light emitting member 16 can be controlled to emit light by the same driving member, or can be independently set, without limitation.

[0074] The material of the substrate of the second back plate 112 can be glass, polycarbonate (PC), acrylonitrile-butadiene-styrene (ABS), ITO (indium tin oxide) film, silicon dioxide, amorphous silicon film, etc., without limitation. Specifically, the substrate of the second back plate 112 is prepared by using a glass substrate and a TGV (Through-Glass Via) glass via technology. The second back plate 112 can also be integrally arranged with the driving member corresponding to the third light emitting member 16.

[0075] The material of the second encapsulation adhesive layer 114 can be an optical grade epoxy resin encapsulation adhesive with high light transmittance, high refractive index and low viscosity.

[0076] Optionally, in the orthographic projection in the first direction X, the third light emitting member 16 is located between the first light transmission area 141 and the second light transmission area 142, and the third light emitting member 16 is spaced apart from the first light transmission area 141 and the second light transmission area 142.

[0077] In this way, the third light emitting member 16 is a front view viewing angle of the display panel 100 compared with the first light emitting member 12 and the second light emitting member 13, so the display panel 100 corresponding to the pixel structure 10 is added. The field of view angle is expanded, and the viewing angle of the display panel 100 corresponding to the pixel structure 10 is expanded, so that the display panel 100 in a limited range can display more viewing angles.

[0078] For reference Figure 4 , Figure 5 and Figure 6 In an embodiment, the direction opposite to the light shielding layer 14 of the first back plate 111 is the first direction X, the first light emitting member 12 and the second light emitting member 13 are oppositely spaced apart, and the direction opposite to the first light emitting member 12 and the second light emitting member 13 is the second direction Y.

[0079] In the orthographic projection in the first direction X, the first light emitting member 12 and the first light transmission area 141 are spaced apart in the third direction Z, the second light emitting member 13 and the second light transmission area 142 are spaced apart in the third direction Z, the first light transmission area 141 and the second light transmission area 142 are spaced apart in the second direction Y and the third direction Z, and the first direction X, the second direction Y and the third direction Z intersect each other.

[0080] Optionally, in the orthographic projection in the first direction X, the first light emitting member 12 and the first light transmission area 141 are correspondingly arranged. Specifically, the cross-sectional shape of the first light emitting member 12 is rectangular, and the cross-sectional shape of the first light transmission area 141 is correspondingly rectangular; the cross-sectional shape of the first light emitting member 12 is circular, and the cross-sectional shape of the first light transmission area 141 is correspondingly circular, without limitation.

[0081] Optionally, in the orthographic projection in the first direction X, the first light emitting member 12 is parallel to the first light transmission area 141, and the second light emitting member 13 is parallel to the second light transmission area 142.

[0082] Reference can be made to Figure 7 Optionally, the surface of the light shielding layer 14 facing away from the first light emitting member 12 and the second light emitting member 13 is provided with a second protective layer 18, the second protective layer 18 is a transparent film layer, and the material of the second protective layer can be polycarbonate (PC), polyethylene terephthalate (PET), polytetrafluoroethylene (PTFE), etc., without limitation.

[0083] In this way, the relative positions of the first light transmission area 141 and the first light emitting member 12, and the second light transmission area 142 and the second light emitting member 13 are limited, and the oblique viewing angle offset from the center of the display panel 100 can still be met, and the multi-viewing angle display requirement of the display panel 100 can be met.

[0084] Reference can be made to Figure 4 , Figure 5 and Figure 6 In an embodiment, the pixel structure 10 further includes a fourth light emitting member 17, the fourth light emitting member 17 is arranged between the first light emitting member 12 and the second light emitting member 13; and the light shielding layer 14 further includes a third light transmission area 143, the third light transmission area 143 is arranged opposite to the fourth light emitting member 17 in the first direction X.

[0085] Optionally, in the orthographic projection in the first direction X, the third light transmission area 143 overlaps the fourth light emitting member 17.

[0086] Optionally, in the orthographic projection in the first direction X, the first light transmission area 141 and the second light transmission area 142 are symmetrical compared to the third light transmission area 143; and the first light emitting member 12 and the second light emitting member 13 are symmetrical compared to the fourth light emitting member 17.

[0087] Optionally, the first light emitting member 12, the second light emitting member 13, and the fourth light emitting member 17 can be controlled to emit light by the same driving member, or can be independently arranged, without limitation.

[0088] In this way, the fourth light emitting member 17 is a front view viewing angle of the display panel 100 compared to the first light emitting member 12 and the second light emitting member 13, and therefore the corresponding field of view of the display panel 100 of the pixel structure 10 is increased, and the viewing angle of the corresponding display panel 100 of the pixel structure 10 is enlarged, so that the display panel 100 in a limited range can display more viewing angles.

[0089] The pixel structure 10 of the embodiment only adopts the structure of one back plate and light emitting pieces, each light emitting piece corresponds to a light transmission area, and different light transmission areas are arranged at different positions of the light shielding layer 14 above the light emitting pieces to realize the display of pictures with different viewing angles and meet the requirement of corresponding display pictures with different viewing angles.

[0090] For reference Figure 1 , Figure 3 and Figure 5 , the application provides a display panel 100 comprising a plurality of pixel structures 10 according to any one of the preceding embodiments, the first back plates 111 of the plurality of pixel structures 10 are integrated structures, and the light shielding layers 14 of the plurality of pixel structures 10 are integrated structures.
