[0049] Optionally, the first light-transmitting area 141 and the second light-transmitting area 142 have the same size.

[0050] The pixel structure 10 of the present application is provided with a first light-emitting element 12 and a second light-emitting element 13, and a first light-transmitting area 141 and a second light-transmitting area 142 are correspondingly provided on the light-shielding layer 14, and the viewing angles corresponding to the light transmitted through the first light-transmitting area 141 and the second light-transmitting area 142 do not overlap, so that users with different viewing angles can all view the corresponding pictures from the display panel 100 corresponding to the pixel structure 10, that is, within a limited space, the pixel structure 10 can enable the corresponding display panel 100 to achieve multiple viewing angles and display requirements corresponding to different pictures.

[0051] For reference Figure 1In one embodiment, the direction in which the first back plate 111 and the light shielding layer 14 are opposite to each other is the first direction X, the first light emitting element 12 and the second light-transmitting area 142 are opposite to each other in the first direction X, and the second light emitting element 13 and the first light-transmitting area 141 are opposite to each other in the first direction X. The first light emitting element 12 has a first light emitting surface 121, and the second light emitting element 13 has a second light emitting surface 131. The first light emitting surface 121 and the surface of the light shielding layer 14 facing the light emitting element have an angle, and at least part of the vertical line of the first light emitting surface 121 passes through the first light-transmitting area 141. The second light emitting surface 131 and the surface of the light shielding layer 14 facing the light emitting element have an angle, and at least part of the vertical line of the second light emitting surface 131 passes through the second light-transmitting area 142. The distance between the first light emitting surface 121 and the second light emitting surface 131 in the second direction Y gradually increases in the direction close to the light shielding layer 14. The second direction Y is the direction in which the first light emitting element 12 and the second light emitting element 13 are opposite to each other.

[0052] Optionally, the first light-emitting element 12 includes a first light-emitting layer 122, and the first light-emitting layer 122 is used to emit light. The first light-emitting layer 122 may be an MQWs light-emitting layer, and the MQWs light-emitting layer is composed of a structure composed of multiple alternating thin layers and barrier layers. When the first light-emitting element 12 is used to emit red light, the material of the first light-emitting layer 122 may be a phosphorescent material, specifically rubrene, PTPP, DCJTB, Tz-Gl, etc., without limitation. When the first light-emitting element 12 is used to emit green light, the material of the first light-emitting layer 122 may be a phosphorescent material, specifically Al aq3, TDETE, Coumar in, NpG l, etc., without limitation. When the first light-emitting element 12 is used to emit blue light, the material of the first light-emitting layer 122 may be a fluorescent material, a phosphorescent material, etc., without limitation.

[0053] The structures and materials of the second light-emitting element 13 , the second light-emitting surface 131 and the second light-emitting layer 132 may refer to the first light-emitting element 12 and are not limited thereto.

[0054] The first light emitting surface 121 and the second light emitting surface 131 are flared as a whole, so that the viewing angles corresponding to the first light emitting element 12 and the second light emitting element 13 can meet the oblique viewing angle offset relative to the center of the display panel 100, meeting the multi-viewing angle display requirements of the display panel 100.

[0055] For reference Figure 1 In one 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, satisfying: 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] α corresponds to the viewing angle provided by the first light-emitting element 12 and the light passing through the first light-transmitting area 141, and β corresponds to the viewing angle provided by the second light-emitting element 13 and the light passing through the second light-transmitting area 142. 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 viewing angle corresponding to the light passing through the first light-transmitting area 141 and / or the second light-transmitting area 142 is too narrow, which is not conducive to the user viewing the display panel 100; when α>60° and / or β>60°, the viewing angle corresponding to the light passing through the first light-transmitting area 141 and / or the second light-transmitting area 142 tends to the middle of the display panel 100, which easily leads to poor display effect corresponding to the middle area of ​​the display panel 100.

[0059] For reference Figure 1 In one embodiment, the pixel structure 10 further includes a support frame 15, which is disposed 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 member 12 and the second light emitting member 13 from being damaged by the external environment, and at the same time support the first light emitting member 12 and the second light emitting member 13 .

[0061] The support frame 15 is composed of one or more layers of insulating material, and is used to isolate the first light-emitting element 12 and the second light-emitting element 13 from direct contact with the external circuit and the 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 mechanical damage or chemical corrosion during the manufacturing and packaging process. The support frame 15 can be an inorganic insulating material, an organic insulating material, etc., without limitation.

[0062] The plurality of support frames 15 are disposed at intervals on the first back plate 111 , or the plurality of support frames 15 may be connected in sequence.

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

[0064] A support frame 15 is provided to support the first light emitting component 12 and the second light emitting component 13, so that the first light emitting surface 121 and the second light emitting surface 131 have an angle with the surface of the shading layer 14 facing the light emitting component, so that the perpendicular line of the first light emitting surface 121 and the second light emitting surface 131 can have an angle with the second direction Y, thereby generating a display picture of the corresponding viewing angle.

[0065] For reference Figure 1 In one embodiment, in a cross section parallel to both the first direction X and the second direction Y, the cross-sectional shape of the first light-transmitting area 141 is a trapezoid, and the size of the first light-transmitting area 141 in the second direction Y gradually increases from the first back plate 111 toward the light-shielding layer 14.

[0066] Correspondingly, in the cross section parallel to both the first direction X and the second direction Y, the cross section of the second light-transmitting area 142 is a trapezoid, and the size of the second light-transmitting area 142 in the second direction Y gradually increases from the first back plate 111 toward the light shielding layer 14 .

[0067] Specifically, the cross-sectional shape of the first light-transmitting area 141 is an isosceles trapezoid. A light-shielding area 144 is formed between the first light-transmitting area 141 and the second light-transmitting area 142 . The cross-sectional shape of the light-shielding area 144 is complementary to the shapes of the first light-transmitting area 141 and the second light-transmitting area 142 .

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

[0069] In this way, the trapezoidal first light-transmitting area 141 can be arranged corresponding to the inclined first light-emitting surface 121 , so that the display image corresponding to the first light-emitting element 12 has a good display effect.

[0070] For reference Figure 3 In one embodiment, the pixel structure 10 further includes a third light emitting element 16, which is disposed on a side of the light shielding layer 14 facing away from the first light emitting element 12. In the orthographic projection in the first direction X, the third light emitting element 16 is located between the first light transmitting area 141 and the second light transmitting area 142.

[0071] Optionally, the pixel structure 10 also includes a second backplane 112, a second encapsulation adhesive layer 114 and a first protective layer 115. In the first direction X, the second backplane 112, the third light-emitting element 16, the second encapsulation adhesive layer 114 and the first protective layer 115 are stacked in sequence, and the surface of the second backplane 112 facing away from the third light-emitting element 16 is connected to the shading 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 element 12, the second light-emitting element 13 and the third light-emitting element 16 can be controlled to emit light by the same driving element, or can be independently provided 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 TGV (Through-Glass Via) glass through hole technology. The second back plate 112 can also be an integrated layout of the driving component corresponding to the third light-emitting component 16.

[0075] The material of the second packaging adhesive layer 114 can be an optical grade epoxy resin packaging 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 element 16 is located between the first light-transmitting area 141 and the second light-transmitting area 142 , and there is a gap between the third light emitting element 16 and the first light-transmitting area 141 and the second light-transmitting area 142 .

[0077] With such arrangement, the third light-emitting element 16 is a front-viewing angle of the display panel 100 compared to the first light-emitting element 12 and the second light-emitting element 13, thereby increasing the field of view angle of the display panel 100 corresponding to the pixel structure 10, thereby expanding the viewing angle of the display panel 100 corresponding to the pixel structure 10, and allowing the display panel 100 to display more viewing angles within a limited range.

[0078] For reference Figure 4 , Figure 5 and Figure 6 In one embodiment, the direction in which the first back plate 111 and the light shielding layer 14 are opposite to each other is a first direction X, the first light emitting element 12 and the second light emitting element 13 are arranged relatively spaced apart, and the direction in which the first light emitting element 12 and the second light emitting element 13 are opposite to each other is a second direction Y;

[0079] In the orthographic projection on the first direction X, the first light-emitting element 12 and the first light-transmitting area 141 are spaced apart in the third direction Z, the second light-emitting element 13 and the second light-transmitting area 142 are spaced apart in the third direction Z, the first light-transmitting area 141 and the second light-transmitting 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 on the first direction X, the shapes of the first light-emitting element 12 and the first light-transmitting area 141 are correspondingly arranged. Specifically, if the cross-sectional shape of the first light-emitting element 12 is rectangular, the cross-sectional shape of the first light-transmitting area 141 is correspondingly rectangular; if the cross-sectional shape of the first light-emitting element 12 is circular, the cross-sectional shape of the first light-transmitting area 141 is correspondingly circular, without limitation.

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

[0082] For reference Figure 7 Optionally, a second protective layer 18 is provided on the surface of the shading layer 14 facing away from the first light-emitting element 12 and the second light-emitting element 13. The second protective layer 18 is a transparent film layer. 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-transmitting area 141 and the first light-emitting element 12, the second light-transmitting area 142 and the second light-emitting element 13 are limited, and the offset oblique viewing angle relative to the center of the display panel 100 can still be met, thereby meeting the multi-viewing angle display requirements of the display panel 100.

[0084] For reference Figure 4 , Figure 5 and Figure 6 In one embodiment, the pixel structure 10 further includes a fourth light-emitting element 17, which is disposed between the first light-emitting element 12 and the second light-emitting element 13; the light-shielding layer 14 further includes a third light-transmitting area 143, which is disposed opposite to the fourth light-emitting element 17 in the first direction X.

[0085] Optionally, in the orthographic projection in the first direction X, the third light-transmitting area 143 overlaps with the fourth light-emitting element 17 .

[0095] Optionally, the display device also includes a control panel, an interface, a power supply, other components, etc.

[0096] The control board is suitable for receiving signals (such as video signals) from external devices and converting them into signals that can be understood by the driving circuit. The control board can also be used for image processing to optimize the display effect of the image.
