[0082] The present application will be further described below in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application. In addition, it should be noted that, for the convenience of description, only the parts related to the present application are shown in the drawings, but not all the structures. Various modifications and changes can be made in the present application without departing from the spirit or scope of the present application, which will be apparent to those skilled in the art. Thus, the present application is intended to cover the modifications and variations of the present application falling within the scope of the corresponding claims (claimed technical solutions) and their equivalents. It should be noted that the embodiments provided by the present application can be combined with each other without contradiction.

[0083] Figure 1 is a schematic diagram of a display panel provided by the prior art, Figure 2 is Figure 1 is a cross-sectional schematic diagram of a display panel in the direction of aa', with reference to Figures 1-2 In the prior art, a display panel 100 that emits light at an oblique viewing angle is provided, which includes a driving substrate 10, a light emitting device 11, an encapsulation layer OC, and a lens structure 12. For the display panel 100 that needs to emit light at an oblique viewing angle, the lens structure 12 is usually made by imprinting on the light emitting side of the light emitting device 11. Generally speaking, the larger the size of the lens structure 12 and the farther the distance from the light emitting device 11, the more significant the light condensing effect. However, an excessively large lens structure 12 will significantly increase the overall thickness h, easily leading to a decrease in the precision of the imprinting process, and instead weakening the light condensing performance. This contradiction is particularly prominent in application scenarios such as head-up display (HUD) that have strict requirements on structural space and light emitting angle. Such applications often require the light source to have specific oblique light emitting characteristics, and thus need a thicker lens to realize light path regulation, but the excessively increased lens thickness h not only reduces the precision of optical preparation, but also weakens the light condensing performance, having a negative impact on the visual effect of the display panel, such as brightness attenuation, color deviation, and other problems, affecting the visual experience of the end user.

[0084] Among them, the normal viewing angle refers to the observation viewing angle perpendicular to the light emitting surface of the light emitting device, that is, 0 degrees. It can also be understood as looking at the display panel 100 along the z direction in Figure 1 the oblique viewing angle refers to the observation angle that is not perpendicular to the light emitting surface of the light emitting device, that is, from the side.

[0085] To solve the above technical problems, the inventors have provided a display panel and a display device. The display panel includes a driving substrate, a light emitting device, an encapsulation structure, and a lens structure. The light emitting device is electrically connected to one side of the driving substrate. The encapsulation structure covers a light emitting surface of the light emitting device, and includes a side surface and a bottom surface. An included angle between the side surface and the bottom surface is an obtuse angle. The lens structure is located at a side of the encapsulation structure away from the light emitting device, and includes a first lens. The first lens includes a first surface facing the side of the encapsulation structure, and the first surface is convex toward the side of the light emitting device. In a thickness direction of the display panel, the light emitting device, the first lens, and the encapsulation structure at least partially overlap.

[0086] With the above technical solution, the encapsulation structure on the light emitting side of the light emitting device is divided into multiple independent modules. The side surface of the encapsulation structure is used to collect large-angle light leakage to the lens structure, and the lens structure is used to converge light to a diagonal viewing angle. Thus, the diagonal viewing angle brightness of the display panel is improved, color cast is improved, and the diagonal viewing angle display effect of the display panel is improved.

[0087] The above is the core idea of the present application. The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0089] In the embodiments of the present application, the type of the display panel 200 includes, but is not limited to, an LED (Light Emitting Diode, LED) display panel, a Micro LED (Micro Light Emitting Diode Display, Micro LED) display panel, a Mini LED (Mini Light Emitting Diode, Mini LED) display panel, and the like. The type of the display panel is not limited in the embodiments of the present application.

[0090] The light emitting device 30 is electrically connected to one side of the driving substrate 20. The type of the light emitting device 30 includes, but is not limited to, an LED, a Micro-LED, a Mini-LED, and the like. The type of the light emitting device 30 is not limited in the embodiments of the present application.

[0091] The driving substrate 20 comprises a plurality of pixel circuits (not shown in the figure) connected with the light emitting device 30, for providing driving voltage to the light emitting device 30 to control the light emitting brightness. The pixel circuit can be a 2T1C, 4T1C, 7T1C, 7T2C, 8T1C, 8T2C, etc. circuit structure, and the pixel circuit comprises a plurality of thin film transistors (TFT), a storage capacitor, and a metal wiring, etc. film layer structure (not shown in the embodiment of the present application), which should be clear to those skilled in the art and will not be described here.

[0092] In the embodiment of the present application, the packaging structure 40 covers the light emitting surface of the light emitting device 30. The light emitting surface refers to the physical surface of the light emitting device 30 emitting light. The packaging structure 40 comprises a side surface 401 and a bottom surface 402, and the included angle between the side surface 401 and the bottom surface 402 is an obtuse angle. The material of the packaging structure 40 comprises but is not limited to an optically clear adhesive (OCA) and an optical clear resin (OCR) having light transmission. Exemplarily, the included angle between the side surface 401 and the bottom surface 402 of the packaging structure 40 is 120 degrees. The included angle between the side surface 401 and the bottom surface 402 of the packaging structure 40 can also be referred to as an inverse chamfer.

[0093] The lens structure 50 is located on the side of the packaging structure 40 away from the light emitting device 30. The material of the lens structure 50 can adopt a high refractive index transparent material, which can converge the light emitted by the light emitting device 30. The lens structure 50 comprises a first lens 51. The first lens 51 comprises a first surface M1 facing the side of the packaging structure 40, and the first surface M1 protrudes towards the side of the light emitting device 30. The first surface M1 can converge and deflect the light emitted by the light emitting device 30 to the observation viewing angle. Wherein, along the thickness direction Z of the display panel 200, the light emitting device 30, the packaging structure 40 and the first lens 51 at least partially overlap. In this way, the packaging structure 40 and the first lens 51 can converge and tilt the light emitted by the light emitting device 30. Wherein. The observation viewing angle refers to the viewing angle of the user watching the display panel, which is usually an inclined viewing angle in the HUD application. Figure 4

[0094] Compared with the prior art, the packaging structure 40 is cut into a plurality of independent module structures in the embodiment of the present application, and part of the light is recycled to the inclined viewing angle by the side surface of the packaging structure 40. Further considering that the light leakage of the light emitting device 30 usually has a large angle, the included angle between the side surface 401 and the bottom surface 402 of the packaging structure 40 is an obtuse angle. ​The obtuse angle is set. In this way, the side surface 401 is conducive to reflecting the large-view-angle light to the first surface M1, and the part of the light is emitted along the oblique viewing angle after being converged by the first lens 51, thereby realizing the functions of effectively collecting the large-view-angle light and regulating the propagation direction of the large-view-angle light, improving the utilization efficiency of the light emitted along the oblique viewing angle, enhancing the overall light performance, improving the brightness and color cast of the display panel, and finally improving the visual experience of the user.

[0095] On the basis of the above-mentioned embodiments, with reference to Figure 3 , the first lens 51 includes a first edge p1 and a second edge p2, and the first edge p1 and the second edge p2 are arranged along a first direction X and extend along a second direction Y. The first direction X and the second direction Y are perpendicular to each other and parallel to the plane on which the driving substrate 20 is located. In the embodiments of the present application, the first lens 51 can be a long strip-shaped lens structure extending along the Y direction. The packaging structure 40 corresponding to the first lens 51 includes a third edge p3 and a fourth edge p4, and the third edge p3 and the fourth edge p4 are arranged along the first direction X and extend along the second direction Y. Along the first direction X, the distance L1 between the first edge p1 and the light emitting device 30 is greater than the distance L2 between the second edge p2 and the light emitting device 30, and the distance L3 between the third edge p3 and the light emitting device 30 is less than the distance L4 between the fourth edge p4 and the light emitting device 30.

[0096] Wherein, along Figure 1 the X direction, the distance L1 refers to the minimum distance between the first edge p1 of the first lens 51 and the center of the light emitting surface of the light emitting device 30, the distance L2 refers to the maximum distance between the second edge p2 of the first lens 51 and the center of the light emitting surface of the light emitting device 30, and L1 > L2. The distance L3 refers to the maximum distance between the third edge p3 of the packaging structure 40 and the center of the light emitting surface of the light emitting device 30, and the distance L4 refers to the minimum distance between the fourth edge p4 of the packaging structure 40 and the center of the light emitting surface of the light emitting device 30, and L3 < L4. In this way, the center of the first lens 51 corresponding to the light emitting device 30, the center of the packaging structure 40, and the center of the light emitting surface of the light emitting device 30 can be arranged in a staggered manner, and the oblique viewing angle polarization control of the light emitted by the light emitting device 30 along the X direction can be realized on the premise that the light emitting device 30, the first lens 51, and the packaging structure 40 at least partially overlap.

[0097] On the basis of the above-mentioned embodiments, with reference to Figure 4 , the first lens 51 further includes a second surface M2 facing away from the packaging structure 40. Along the first direction X, the included angle between the first surface M1 and the second surface M2 includes a first bottom angle and a second bottom angle , the first bottom angle and the second bottom angle are different, that is, In the embodiment of the present application, the first lens 51 can adopt a non-axially symmetric cylindrical prism. By setting the two opposite base angles of the first lens 51 to be unequal, the asymmetric regulation of the outgoing light path is realized, thereby generating the polarizing effect along a specific direction.

[0098] In an embodiment of the present application, with reference to Figure 3 , the display panel 200 includes a plurality of light emitting devices 30 arranged in an array, and the distance D1 between two light emitting devices 30 arranged adjacent in the first direction X is greater than the distance D2 between two light emitting devices 30 arranged adjacent in the second direction Y. The first lens 51 covers the plurality of light emitting devices 30 arranged in the second direction Y in the orthographic projection of the driving substrate 20.

[0099] In the embodiment of the present application, the light emitting devices 30 of the display panel 200 can have various arrangement modes. According to the distribution characteristics of the spacing between the light emitting devices 30, the layout of the first lens 51 is reasonably set, which can not only guarantee the optical preparation precision, but also optimize the condensing performance. Specifically, the first lens 51 is designed to extend along the Y direction and cover a plurality of light emitting devices 30. This design closely combines the optical structure and device arrangement, not only reduces the preparation difficulty and improves the process feasibility, but also effectively realizes the directional deflection of the outgoing light of the plurality of light emitting devices 30 arranged in the Y direction, so that the light is emitted uniformly in the same direction, thereby significantly improving the uniformity of the light emitting angle and the light regulation effect.

[0100] Figure 5 is another schematic diagram of a display panel provided in an embodiment of the present application. In another embodiment of the present application, with reference to Figure 5 , the present application can also be provided that the first lens 51 covers the plurality of light emitting devices 30 arranged in the first direction X in the orthographic projection of the driving substrate 20. This structure design can realize the directional deflection of the outgoing light of the plurality of light emitting devices 30 arranged in the X direction, so that the light is emitted uniformly in the same direction, thereby improving the uniformity of the light emitting angle and the light regulation effect.

[0101] It should be noted that the embodiment of the present application is only exemplarily described by taking the array arrangement mode of the light emitting device 30 shown in Figure 3 . The structure of the lens structure 50 of the present application is not limited thereto.

[0102] On the basis of the above-mentioned embodiment, with reference to Figure 3 , the light emitting colors of the plurality of light emitting devices 30 are the same along the first direction X. Exemplarily, along the first direction X, the first row is all blue light emitting devices B, the second row is all green light emitting devices G, and the third row is all red light emitting devices R. Along the second direction Y, the light emitting colors of at least two light emitting devices 30 covered by the orthographic projection of the same first lens 51 on the substrate 20 are different.

[0103] Specifically, based on the arrangement of the light emitting device 30 of the existing display panel 200, the first lens 51 is designed to extend along the Y direction and cover a plurality of light emitting devices 30 of different colors. This arrangement can make light of different colors be deflected in the same direction after passing through the same first lens 51 structure, which not only helps to improve the mixing effect between light of different colors, but also effectively improves the display color deviation and other problems.

[0104] Figure 6 is a schematic diagram of another display panel provided by an embodiment of the present application, Figure 7 is Figure 6 is a cross-sectional schematic diagram of a display panel along the BB' direction in the above embodiment, Figure 8 is Figure 6 is a cross-sectional schematic diagram of another display panel along the BB' direction in the above embodiment, based on the above embodiment, with reference to Figures 6-8 , the lens structure 50 further includes a second lens 52, the second lens 52 is located between the adjacent two first lenses 51, and at least partially surrounds the first lens 51. Along the thickness direction Z of the display panel 200, the second lens 52 at least partially overlaps the packaging structure 40.

[0105] Compared with the prior art, the present application cuts the packaging structure 40 into a plurality of independent module structures, and recycles part of the large viewing angle light to the oblique viewing angle by using the side surface of the packaging structure 40, thereby improving the oblique viewing angle brightness. After the brightness is improved, the thickness h1 of the first lens 51 can be thinned, that is, h1 < h, and the second lens 52 is added between the adjacent first lenses 51, and the second lens 52 is used to further recycle the large viewing angle light to the oblique viewing angle, thereby balancing the optical loss caused by thinning. The optical parameters of the second lens 52 and the first lens 51 can be the same or different. Specifically, the present application reflects the large viewing angle light by using the side surface 401 of the packaging structure 40, and uses the second lens 52 to converge the part of the light, enhances the deflection emission brightness of the light, improves the utilization rate of the large viewing angle light, and finally improves the overall light energy utilization rate.

[0106] It should be emphasized that when the thickness h1 of the first lens 51 is thinned, it is beneficial to improve the precision and light condensing performance of the optical preparation of the first lens 51.

[0107] Based on the above embodiment, with reference to Figure 7 , the second lens 52 includes a third surface M3 facing the side of the packaging structure 40, the third surface M3 includes a convex surface n and a concave surface u connected to each other, the convex surface n is located on the side of the concave surface u close to the first lens 51, and protrudes towards the first lens 51. The included angle between the concave surface u and the side surface 401 and the bottom surface 402 of the packaging structure 40 is The convex surface n and the concave surface u form a continuous and smooth third surface M3.

[0108] In the embodiment of the present application, the second lens 52 further comprises a fourth surface M4 facing away from the packaging structure 40. Along the first direction X, the included angle between the convex surface n and the fourth surface M4 is a third bottom angle , and the included angle between the concave surface u and the fourth surface M4 is a fourth bottom angle According to the geometric relationship, The concave surface u of the second lens 52 can deflect a small-angle reflected light to the oblique viewing angle, and the convex surface n can deflect a large-angle reflected light to the oblique viewing angle. In this way, the second lens 52 can at least collect a part of the large-angle light as compensation for the thinning loss of the first lens 51, thereby improving the precision of optical preparation and the condensing performance, and enhancing the deflection and emission effect of the light.

[0109] On the basis of the above-mentioned embodiment, with reference to Figure 7 Along the thickness direction Z of the display panel 200, the thickness h1 of the first lens 51 and the thickness h2 of the second lens 52 are the same, i.e. h1 = h2.

[0110] , along the thickness direction Z of the display panel 200, the thickness h1 refers to the thickness of the first lens 51 from the first surface M1 to the second surface M2, and the thickness h2 refers to the thickness of the second lens 52 from the third surface M3 to the fourth surface M4. The above-mentioned limitation of the thickness of the first lens 51 and the second lens 52 in the embodiment of the present application is beneficial to the precision of the imprint process, can accurately control the deflection of the light path, and realizes the effective convergence of light of different viewing angles.

[0111] On the basis of the above-mentioned embodiment, with reference to Figure 8 The second lens 52 comprises a third surface M3 facing the packaging structure 40 and a fourth surface M4 facing away from the packaging structure 40, and the third surface M3 protrudes towards the light emitting device 30. Along the first direction X, the included angle between the third surface M3 and the fourth surface M4 includes a third bottom angle and a fourth bottom angle , the third bottom angle and the fourth bottom angle The first direction X is parallel to the plane in which the driving substrate 20 is located. In the embodiment, the second lens 52 and the first lens 51 can both be two non-axially symmetric cylindrical prisms, and the first surface M1 of the first lens 51 and / or the third surface M3 of the second lens 52 can be parabolic. For example, a second lens 52 with a smaller size can be directly imprinted in the gap region between two adjacent first lenses 51, and the thicknesses of the two can be different. The first lens 51 converges and deflects the small-angle light of the light-emitting device 30, and the second lens 52 converges and deflects the large-angle light reflected by the side surface 401 of the packaging structure 40.

[0112] On the basis of the above embodiment, with reference to Figure 8 , the first lens 51 further includes a second surface M2 facing away from the packaging structure 40. Along the first direction X, the included angle between the first surface M1 and the second surface M2 includes a first bottom angle and a second bottom angle . Among them, along the X direction, the first bottom angle , the second bottom angle , the third bottom angle , and the fourth bottom angle are arranged in sequence. In the embodiment, the third bottom angle of the second lens 52 is less than or equal to the first bottom angle of the first lens 51, that is, ≤ . The fourth bottom angle of the second lens 52 is less than or equal to the second bottom angle of the first lens 51, that is, ≤ . The example of the present application can narrow the width of the second lens 52 in the X direction by angle setting, and at the same time facilitate the realization of the consistent deflection direction of the second lens 52 and the first lens 51 to the light.

[0113] Among them, the included angle between the third surface M3 and the fourth surface M4 is the third bottom angle , the included angle between the convex surface n and the fourth surface M4 is the third bottom angle , the included angle between the third surface M3 and the fourth surface M4 is the fourth bottom angle , and the included angle between the concave surface u and the fourth surface M4 is the fourth bottom angle .

[0114] On the basis of the above embodiment, with reference to Figure 8 , the first bottom angle of the first lens 51 can be less than or equal to the second bottom angle , that is, ≤ , and the third bottom angle Less than or equal to the fourth base angle ,Right now ≤ For example, the first lens 51 is scaled down proportionally and set as the second lens 52, through reasonable adjustment. , , , This causes the outgoing rays to bend uniformly to the left in the diagram.

[0115] Among them, Figure 8 In the XZ plane, the cross-sectional profiles of the first surface M1 of the first lens 51 and the third surface M3 of the second lens 52 are asymmetrical curves. For example, both the first surface M1 and the third surface M3 can be parabolic surfaces, such as elliptic parabolic surfaces.

[0116] Based on the above embodiments, continue to refer to Figure 6 Along the first direction X, the width D3 of the first lens 51 is greater than the width D2 of the second lens 52. The first direction X is parallel to the plane containing the driving substrate 20. In this embodiment, by providing a smaller second lens 52 in the gap region between two adjacent first lenses 51, the second lens 52 converges the large-viewing-angle light leakage reflected from the side surface 401 of the packaging structure 40, thereby improving brightness and reducing color shift.

[0117] Figure 9 This is a schematic diagram of another display panel provided in an embodiment of this application. Figure 10 yes Figure 9 A cross-sectional schematic diagram of a display panel along the CC' direction. In another embodiment of this application, a first lens 51 may also be provided for the emitted light from a single light-emitting device 30. (Refer to...) Figure 9 and Figure 10 The first lens 51, projected onto the driving substrate 20, covers a light-emitting device 30. The center of the first lens 51 does not coincide with the center of the light-emitting device 30 along the thickness direction Z of the display panel 200.

[0118] For example, refer to Figure 9 The shape of the orthographic projection of the first lens 51 onto the driving substrate 20 is circular or elliptical. The center of the orthographic projection of the first lens 51 onto the driving substrate 20 does not coincide with the center of the orthographic projection of the light-emitting surface of the light-emitting device 30 onto the driving substrate 20. This configuration allows the first lens 51 to deflect the emitted light from the light-emitting device 30 at an oblique angle.

[0119] It should be noted that the optical relationships between the first lens 51 and the second lens 52 as defined in the above embodiments also apply to the embodiments of this application, such as the first bottom angle between the first surface M1 and the second surface M2 of the first lens 51. Second bottom angle The distance relationship between the first edge p1 and the second edge p2 of the first lens 51, the third edge p3 and the fourth edge p4 of the encapsulation structure 40 and the light-emitting device 30, etc., will not be described again in the embodiments of this application.

[0120] This application utilizes precise micro-optical processes to independently fabricate and align the first lens 51 with each individual light-emitting device 30. This lens enables precise control of the light path emitted by the light-emitting device 30, causing the light to be deflected and emitted in a preset direction. This allows for individual control of the light emission angle and the light propagation path. Simultaneously, the inverted corner of the encapsulation structure 40 converges light from a wide viewing angle to the deflection direction, thereby enhancing the overall light effect, improving the brightness of the display panel, and mitigating color shift issues, ultimately improving the user's visual experience.

[0121] Figure 11 This is a schematic diagram of another display panel provided in an embodiment of this application. Figure 12 yes Figure 11 A cross-sectional schematic diagram of a display panel along the DD' direction is shown below. Further reference is made to the above embodiment. Figure 11 and Figure 12 The first lens 51, in its orthogonal projection onto the driving substrate 20, covers a light-emitting device 30. The lens structure 50 also includes a third lens 53 and a fourth lens 54. Both the third lens 53 and the fourth lens 54 partially surround the first lens 51. Exemplarily, the orthogonal projections of the third lens 53 and the fourth lens 54 onto the substrate 20 are strip-shaped, partially surrounding the first lens 51.

[0122] refer to Figure 12 Along the first direction X, the side surface 401 of the packaging structure 40 includes a first side surface 4a and a second side surface 4b, and the included angle between the first side surface 4a and the bottom surface 402 is the first included angle. The included angle between the second side surface 4b and the bottom surface 402 is the second included angle. For example, the first side 4a and the second side 4b can be two consecutive regions of side 401.

[0123] refer to Figure 12 The third lens 53 includes a fifth surface M5 facing the side of the packaging structure 40. The fifth surface M5 protrudes towards the side of the light-emitting device 30 and towards the first included angle. The fourth lens 54 includes a sixth surface M6 facing the side of the packaging structure 40. The sixth surface M6 protrudes towards the side of the light-emitting device 30 and towards the second included angle. Specifically, with this structural design, the first portion of the light emitted from the light-emitting device 30, S1, is reflected by the first side 4a to the third lens 53, and after being converged, it is emitted along the A+ direction. The second portion of the light, S2, is converged by the third lens 53 and emitted along the A+ direction. The third portion of the light, S3, is converged by the third lens 53 and emitted along the A- direction. The fourth portion of the light, S4, is reflected by the second side 4b to the third lens 53, and after being converged, it is emitted along the A- direction, thus achieving a bidirectional focusing effect along the A+ and A- directions respectively.

[0124] Bidirectional focusing refers to the focusing of light emitted from a light-emitting device on a two-dimensional plane along different directions. The A+ direction can be... Figure 12 The positive X-direction in the XZ plane, and the A-direction can be... Figure 12 The negative direction of the X direction in the XZ plane, or the A+ direction, can be... Figure 12 The positive Y-direction in the XY plane, and the A-direction can be... Figure 12 In the XY plane, the negative direction of the Y direction is not limited to the A+ and A- directions in this embodiment of the application; the A+ and A- directions are simply different.

[0125] Figure 13 yes Figure 11 A cross-sectional schematic diagram of another display panel along the DD' direction, in another embodiment of this application, refers to... Figure 13 The third lens 53 and the fourth lens 54 can also be used Figure 7 The structural design of the second lens 51 shown, the fifth surface M5 of the third lens 53 and the sixth surface M6 of the fourth lens 54 are both composed of a convex surface n and a concave surface u, which converge and deflect light rays with a large viewing angle.

[0126] In summary, the embodiments of this application can reasonably adjust the surface shape and focusing direction of the third lens 53 and the fourth lens 54 according to the bidirectional tilt display requirements of the display panel, so as to realize the convergence and deflection of light emitted from the light-emitting device 30 in different directions with a wide viewing angle, and improve the efficiency of bidirectional tilt light emission of the light source.

[0127] Optional, see reference Figure 12 First included angle Second angle The sizes are the same. In this embodiment, the side 401 of the encapsulation structure 40 is a bevel, and all the chamfers of the bevel are basically the same. This design allows the light emitted by the light-emitting device 30 to obtain a more uniform reflection effect. For example, the first included angle Second angle The range is 90° to 120°. For example, and Both can be 100°. If the first included angle... and the second included angle less than 90°, the side surface 401 of the packaging structure 40 reflects the large-view-angle light rays to a larger exit angle, so that the purpose of exiting in the preset oblique angle direction cannot be achieved; if the first included angle and the second included angle greater than 120°, the side surface 401 of the packaging structure 40 cannot recycle the large-view-angle light rays. The present application limits the first included angle and the second included angle in the above range, so as to meet the purpose of reflecting the large-view-angle light rays to the preset oblique angle to achieve recycling.

[0128] On the basis of the above embodiment, with reference to Figures 11-13 , the third lens 53 and the fourth lens 54 at least partially overlap the packaging structure 40 along the thickness direction Z of the display panel. This design enables the light rays reflected by the side surface 401 of the packaging structure 40 to be effectively collected and converged by the third lens 53 and the fourth lens 54.

[0129] On the basis of the above embodiment, with reference to Figure 11 , the light emitting device 30 includes a first virtual axis X1, the first virtual axis X1 overlaps the center of the light emitting device 30 and extends along the first direction X. The third lens 53 and the fourth lens 54 are symmetrical about the first virtual axis X1. Through this design, the third lens 53 and the fourth lens 54 can respectively symmetrically fold and converge the light rays in the A+ and A- directions, so as to achieve efficient bidirectional light converging effect.

[0130] On the basis of the above embodiment, with reference to Figure 11 , the light emitting device 30 further includes a second virtual axis X2, the second virtual axis X2 overlaps the center of the light emitting device 30 and extends along the second direction Y. The third lens 53 and the fourth lens 54 are located on the same side of the second virtual axis X2. In this way, the third lens 53 and the fourth lens 54 can fold and converge the converged light rays in two opposite directions of the first virtual axis X1.

[0131] Figure 15 is a schematic view of another display panel provided by an embodiment of the present application, Figure 16 is a schematic view of another display panel provided by an embodiment of the present application, Figure 17 is a schematic view of another display panel provided by an embodiment of the present application, on the basis of the above embodiment, with reference to Figures 15-17The light-emitting device 30 includes a first light-emitting device 31 and a second light-emitting device 32. The light-emitting brightness of the first light-emitting device 31 at the first viewing angle is less than the light-emitting brightness of the second light-emitting device 32 at the first viewing angle. The lens structure 50 includes a first lens structure 501 and a second lens structure 502. Along the thickness direction Z of the display panel, the first lens structure 501 and the first light-emitting device 31 at least partially overlap, and the second lens structure 502 and the second light-emitting device 32 at least partially overlap.

[0132] The first viewing angle refers to the angle range at which the light-emitting surface of the light-emitting device is collected by the detector or observed by the user. For example, the included angle range of the light rays covered by the angle range with respect to the normal line of the light-emitting surface is 30-90°. It should be noted that the first viewing angle is a reference angle reasonably set based on display needs, and the embodiments of the present application do not make specific limitations.

[0133] In some embodiments, with reference to Figure 15 The first light-emitting device 31 and the second light-emitting device 32 are light-emitting devices with different light-emitting colors, for example, the first light-emitting device 31 is a red light-emitting device R, and the second light-emitting device 32 is a green light-emitting device G or a blue light-emitting device B. Due to the light-emitting characteristics of the light-emitting material of the light-emitting device 30 and the refraction characteristics of the lens refractive index to light, when the first light-emitting device 31 and the second light-emitting device 32 with different light-emitting colors are observed at the same viewing angle (the first viewing angle), there is a difference in light-emitting brightness. For example, with reference to Figure 14 As the viewing angle changes from 0 to 90° and from 0 to -90°, the large-viewing-angle light-emitting brightness of the green light-emitting device G and the blue light-emitting device B is greater than that of the red light-emitting device R. That is, the large-viewing-angle light leakage of the green light-emitting device G and the blue light-emitting device B is greater than that of the red light-emitting device R. Based on this, the present application can adjust the light path structure corresponding to the light-emitting device with more large-viewing-angle light leakage, thereby improving the light-emitting brightness at the preset inclined viewing angle.

[0134] In some embodiments, with reference to Figure 16 The first light-emitting device 31 can refer to the sum of all light-emitting devices in the first column, and the second light-emitting device 32 can refer to the sum of all light-emitting devices in the second column. When the light-emitting devices in different columns are observed at the same viewing angle (the first viewing angle), there is a difference in light-emitting brightness between the two columns.

[0135] The present application differentiates at least one parameter in the curved surface type, refractive index, and width of the lens structure 50 corresponding to the light-emitting devices with different light-emitting brightness at the same viewing angle, so as to make the brightness of different light-emitting devices consistent at the preset inclined viewing angle.

[0136] Specifically, the first lens structure 501 and the second lens structure 502 can be set to have different curvatures of the first surfaces; and / or different refractive indexes; and / or different widths in the first direction X, which is parallel to the plane where the driving substrate 20 is located.

[0137] Specifically, the first lens structure 501 and the second lens structure 502 have different curvatures of the first surfaces facing the light-emitting device 30, and different converging effects on the same angle light rays. The first lens structure 501 and the second lens structure 502 have different refractive indexes, and different converging effects on the same angle light rays. The first lens structure 501 and the second lens structure 502 have different widths in the X direction parallel to the plane where the driving substrate 20 is located, and different converging effects on the same angle light rays. Therefore, at least one of the curvatures, the refractive indexes, and the widths in the X direction parallel to the plane where the driving substrate 20 is located of the first lens structure 501 and the second lens structure 502 can be set to be different, so as to collect the large-angle light leakage, balance the light-emitting quantity of the inclined light rays emitted by the first light-emitting device 31 and the second light-emitting device 32, and avoid the problem of color deviation of the display panel.

[0138] On the basis of the above-mentioned embodiments, referring to Figure 16 and Figure 17 , the number of lenses in the first lens structure 501 is less than that in the second lens structure 502. In the embodiments of the present application, for the first light-emitting device 31 with less light leakage at a large angle (the same angle), the number of large-angle recycling lenses corresponding thereto can be reduced or removed, so as to balance the consistency of the light-emitting angle distribution of the light-emitting device and reduce the preparation cost and the lens preparation process.

[0139] Exemplarily, referring to Figure 16 , at the same inclined viewing angle, the light-emitting brightness of the first light-emitting device 31 is lower than that of the second light-emitting device 32, the first lens structure 501 corresponding to the first light-emitting device 31 comprises one first lens 51, and the second lens structure 502 corresponding to the second light-emitting device 32 comprises one first lens 51 and one second lens 52. By setting the second lens 52 at the position of the second light-emitting device 32, the large-angle light leakage of the second light-emitting device 32 is converged by the second lens 52, so that the light-emitting brightness of the first light-emitting device 31 and the second light-emitting device 32 at the preset inclined viewing angle is consistent.

[0140] Exemplarily, referring to Figure 17, the first light emitting device 31 is a red light emitting device R, and the corresponding first lens structure 501 comprises a first lens 51. The second light emitting device 32 is a green light emitting device G or a blue light emitting device B, and the corresponding second lens structure 502 comprises a first lens 51, a third lens 53 and a fourth lens 54. The third lens 53 and the fourth lens 54 are used to converge the large-angle light leakage of the second light emitting device 32, so that the light emitting brightness of the first light emitting device 31 and the second light emitting device 32 is consistent at a preset bidirectional inclined viewing angle.

[0141] On the basis of the above-mentioned embodiments, with reference to Figure 16 , along the first direction X, the width N1 of the first lens structure 501 is less than the width N2 of the second lens structure 502, that is, N1 < N2. In the embodiments of the present application, by increasing the width N2 of the second lens structure 502, more large-angle light leakage of the second light emitting device 32 is converged, so that the light emitting brightness of the first light emitting device 31 and the second light emitting device 32 is consistent at a preset inclined viewing angle.

[0142] Figure 18 is Figure 15 , on the basis of the above-mentioned embodiments, with reference to Figure 18 , the packaging structure 40 comprises a first packaging structure 41 and a second packaging structure 42; the first packaging structure 41 covers the light emitting surface of the first light emitting device 31, and the second packaging structure 42 covers the light emitting surface of the second light emitting device 32. The included angle between the side surface and the bottom surface of the first packaging structure 41 is less than the included angle between the side surface and the bottom surface of the second packaging structure 42 , . In the embodiments of the present application, by increasing the inverse chamfer of the second packaging structure 42, more large-angle light leakage of the second light emitting device 32 is reflected to the second lens structure 502 through the inclined side surface of the second light emitting device 32, so that the light emitting brightness of the first light emitting device 31 and the second light emitting device 32 is consistent at a preset inclined viewing angle.

[0143] On the basis of the above-mentioned embodiments, with reference to Figure 18 , along the thickness direction Z of the display panel 200, the thickness H1 of the first lens structure 501 is less than the thickness H2 of the second lens structure 502. In the embodiments of the present application, the thickness H1 of the first lens structure 501 can also be appropriately reduced to improve the precision of the imprint process of the first lens structure 501, improve the light convergence ability, and balance the light emitting brightness of the first light emitting device 31 and the second light emitting device 32 at a preset inclined viewing angle.

[0144] On the basis of the above-mentioned embodiments, with reference to Figure 18As shown, the packaging structure 40 also includes a top surface 403, and the area of the top surface 403 is greater than the area of the bottom surface 402. Exemplarily, the packaging structure 40 is a reverse trapezoidal structure, which is designed to facilitate the light reflected by the side surface 401 to converge to the lens structure 50.

[0145] wherein, Figures 2-17 In the above embodiment, the top surface of the packaging structure 40 is not shown, and only the Figure 18 is described by way of example.

[0146] On the basis of the above embodiment, referring to Figures 2-18 , the display panel 200 also includes a filling layer (not shown in the figure) arranged between adjacent packaging structures 40, and the refractive index of the filling layer is less than the refractive index of the packaging structure 40.

[0147] Exemplarily, the gap between adjacent packaging structures 40 can be in a vacuum state, and the extremely low refractive index characteristics thereof help to achieve total reflection of the large-view-angle light at the side surface 401 of the packaging structure 40, thereby guiding the light to the lens structure 50, and effectively enhancing the reflection effect of the inverse corner structure on the large-view-angle light. Alternatively, the gap can also be filled with a transparent material with a relatively low refractive index, such as optical glue. When the large-view-angle light reaches the interface at a large incident angle, a relatively high reflectivity can still be maintained; and when the incident angle of the light is small, more light will be transmitted, which helps to regulate the light field distribution under different viewing angles.

[0148] In addition, to further improve the optical performance, a reflective layer can be prepared on the surface of the side surface 401 of the packaging structure 40. The reflective layer can significantly increase the reflection efficiency of the large-view-angle light, ensure that more light is effectively utilized, and thus optimize the overall brightness and viewing angle performance of the display panel.
