Technical Field
[0001] This application relates to the field of display technology, and more specifically to a display panel and display device. Background Technology
[0002] In the application of display panels, including automotive display panels, the display panel located in the passenger seat needs to have the function of preventing the display from affecting the driver's view, preventing driving interference, and improving safety during the journey. Summary of the Invention
[0003] In view of this, this application provides a display panel and a display device to help solve the above problems.
[0004] In a first aspect, embodiments of this application provide a display panel, including: a substrate;
[0005] The lens layer includes a lens group, which includes multiple lenses. The surface of the lens away from the substrate protrudes towards the light-emitting surface of the display panel.
[0006] The light-emitting layer is located between the lens layer and the substrate. The light-emitting layer includes sub-pixels. In a direction perpendicular to the plane of the display panel, at least one lens group overlaps with the sub-pixels. The extension length of the lens group along a first direction is greater than the extension length of the sub-pixels along the first direction. The extension length of the lens group along a second direction is greater than the extension length of the sub-pixels along the second direction. Both the first and second directions are parallel to the plane of the display panel, and the second direction intersects the first direction.
[0007] Secondly, embodiments of this application provide a display device, including a display panel as provided in the first aspect.
[0008] In this embodiment, the display panel includes a lens layer, which facilitates focusing the light emitted from the light-emitting layer, enabling the display panel to provide a privacy protection effect at certain angles and increasing its applicability in the privacy protection field. Furthermore, including multiple lenses in the same lens group allows for the reduction of the height of individual lenses by utilizing the combined effect of multiple lenses; it avoids the risk of compromising the thinness of the display panel by setting the lens too high to improve light processing when only one lens is included in the lens group. Moreover, the distribution of multiple smaller lenses in the lens layer not only improves the thinness of the display panel when privacy protection is included but also enhances the light processing effect of the lens layer, maximizing the uniformity of light distribution by altering the optical path, thereby improving the display effect and enhancing the user's visual experience. Furthermore, this embodiment includes a lens group covering the sub-pixels, ensuring that all light emitted from the sub-pixels towards the display panel passes through the lens group before exiting, preventing any light from being missed and improving the light processing effect from the sub-pixels, further enhancing the privacy protection performance of the display panel.

[0055] Figure 1 This is a plan view of a display panel provided in an embodiment of this application. Figure 2 An embodiment provided in this application Figure 1 A cross-sectional view along the A-A' direction.
[0056] This application embodiment provides a display panel 100, combined with... Figure 1 , Figure 2 As shown, the display panel 100 includes a substrate 10, and multiple film layers of the display panel 100 are fabricated on one side of the substrate 10. The display panel 100 also includes a lens layer 20, which includes a lens group 20A. The lens group 20A includes multiple lenses 20A1, and the surface of the lenses 20A1 away from the substrate 10 protrudes towards the light-emitting surface of the display panel 100. Optionally, the lenses 20A1 in the lens group 20A are convex lenses. Including multiple lenses in a lens group 20A is beneficial to improving the light processing effect of the lens group 20A and to avoiding the risk of a single light processing path when there is only one lens 20A1.
[0057] The display panel 100 also includes a light-emitting layer 30 located between the lens layer 20 and the substrate 10. Specifically, the lens layer 20 is fabricated on the side of the light-emitting layer 30 facing the light-emitting surface of the display panel 100, allowing the emitted light from the light-emitting layer 30 to pass through the lens layer 20. When the light emitted from the light-emitting layer 30 passes through the lens layer 20, it passes through multiple lenses 20A1 in the lens group 20A, which focus the light.
[0058] In applications such as driving, using a lens layer 20 in the display panel 100 shown in the passenger seat position helps to focus the light emitted from the light-emitting layer 30, preventing the light from being too scattered and affecting the driver's visibility.
[0059] The light-emitting layer 30 includes a sub-pixel 30A. At least one lens group 20A overlaps with the sub-pixel 30A in a direction perpendicular to the plane of the display panel 100. Optionally, one lens group covers one sub-pixel 30A. The extension length of the lens group 20A along a first direction X1 is greater than the extension length of the sub-pixel 30A along the first direction X1, and the extension length of the lens group 20A along a second direction X2 is greater than the extension length of the sub-pixel 30A along the second direction X2. The lens group 20A completely covers the sub-pixel 30A. Both the first direction X1 and the second direction X2 are parallel to the plane of the display panel 100, and the second direction X2 intersects the first direction X1.
[0060] In this embodiment, the display panel 100 includes a lens layer 20, which facilitates focusing the light emitted from the light-emitting layer 30 using the lens layer 20. This allows the display panel 100 to have a privacy protection effect at a certain angle, increasing its applicability in the privacy protection field. Furthermore, including multiple lenses 20A1 in the same lens group 20A allows for the combined effect of multiple lenses 20A1 to reduce the height of a single lens 20A1. This avoids the risk of the lens 20A1 being set too high to improve its light processing effect when the lens group 20A includes only one lens 20A1, which could negatively impact the thinness and lightness of the display panel 100. Moreover, the distribution of multiple smaller lenses 20A1 in the lens layer 20A not only improves the thinness and lightness of the display panel when including the privacy protection function, but also enhances the light processing effect of the lens layer 20A. By changing the optical path, it maximizes the uniformity of light distribution, improves the display effect of the display panel 100, and enhances the user's visual experience. Furthermore, in this embodiment, the lens group 20A is set to cover the sub-pixel 30A, which is beneficial to ensure that all light emitted from the sub-pixel 30A toward the display panel 100 passes through the lens group 20A before being emitted, avoiding the omission of some light, which is beneficial to improving the light processing effect of the sub-pixel 30A and further improving the privacy performance of the display panel 100.
[0061] Figure 3 This is a planar schematic diagram of a lens group for comparison reference provided in an embodiment of this application.
[0062] In one embodiment of this application, reference continues to be made to... Figure 1 , Figure 2 As shown, in the same lens group 20A, two adjacent lenses 20A1 at least partially overlap.
[0063] To better illustrate the technical solution of this application, a lens schematic diagram is provided for comparison with the embodiments of this application. Figure 3 . refer to Figure 3As shown in Figure (a), when the lens 20A1 is circular, even though multiple lenses 20A1 are arranged relatively closely together, it is conceivable that some gaps will exist between the circular structures. These gaps will expose part of the light-emitting layer 30, thus posing a risk that the light emitted from part of the light-emitting layer 30 cannot be altered in its optical path, which is detrimental to improving the privacy protection effect of the display panel 100. Alternatively, continue to refer to... Figure 3 As shown in Figure (b), when the lens 20A1 is square, the surface of the square lens protrudes towards the light-emitting surface of the display panel 100. When multiple lenses 20A1 are arranged close together without overlapping, the lens structure in the edge region between two adjacent lenses 20A1 has a smaller degree of protrusion, resulting in poor light processing in this area. There is a risk that the light emitted from this edge region will have a smaller change in its optical path, which is also detrimental to improving the privacy protection effect of the display panel 100.
[0064] In the embodiments of this application, reference continues to be made to Figures 1-2 As shown, by setting adjacent lenses 20A1 in the same lens group 20A to at least partially overlap, gaps between multiple adjacent lenses 20A1 in the prepared lens group 20A are avoided. This helps ensure the coverage effect of the lens group 20A on the sub-pixel 30, ensuring that all light emitted from the sub-pixel 30 passes through the lens group 20A before exiting, thus improving the thoroughness of light processing by the lens layer 20. Furthermore, at least partial overlap of adjacent lenses 20A1 also helps avoid the risk of poor light processing at the edges between lenses 20A1, increasing the probability that light can pass through areas where the light path is more significantly altered, thereby improving the performance of the lens group 20A and enhancing the privacy protection capability of the display panel 100.
[0065] Figure 4 Another embodiment provided in this application Figure 1 A cross-sectional view along the A-A' direction. Figure 5 Another embodiment provided in this application Figure 1 A cross-sectional view along the A-A' direction. Figure 6 Another embodiment provided in this application Figure 1 A cross-sectional view along the A-A' direction.
[0066] In one embodiment of this application, combined with Figure 1 , Figures 4-6As shown, along the direction perpendicular to the plane of the display panel 100, the maximum height of the portion of lens 20A1 located in lens layer 20 is H. Considering that the surface of lens layer 20 facing the light-emitting layer 30 is parallel to the horizontal coordinate axis X and perpendicular to the vertical coordinate axis Y, the surface of lens layer 20 facing the light-emitting layer 30 can be set as a horizontal plane, and the overlap position coordinates of two adjacent lenses 20A1 can be set as (0, D1), -1 H≤D1≤(4 / 5) H ensures that the overlapping position coordinates of two adjacent lenses 20A1 are within a preset range, which helps to improve the feasibility of the embodiments of this application and to adjust the preparation of the lens 20A1 in an applicable way, thereby improving the light processing effect of the lens group 20A and improving the privacy protection effect of the display panel 100.
[0067] Optionally, such as Figure 4 As shown, the coordinates of the overlap position of two adjacent lenses 20A1 are set to (0, -1). H), such that a portion of the lens 20A1 is located in the film layer between the lens layer 20 and the sub-pixel 30A in the light-emitting layer 30. Optionally, an encapsulation layer 40 is also included between the lens layer 20A1 and the sub-pixel 30A. The encapsulation layer 40 can be used to flatten the surface of the sub-pixel 30A and protect the sub-pixel 30A from damage such as water and oxygen erosion. The encapsulation layer 40 has a certain thickness, and the light emitted from the sub-pixel 30A needs to pass through the encapsulation layer 40 before reaching the lens layer 20A1. Therefore, in this embodiment, setting the overlapping position of the two lenses 20A1 to occupy part of the space of the encapsulation layer 40 below the lens layer 20 is beneficial to allow at least some light to reach the lens 20A1 and be processed earlier, and is also beneficial to reduce light loss and improve the display effect of the display panel 100.
[0068] Optionally, such as Figure 5 As shown, the coordinates of the overlapping position of two adjacent lenses 20A1 are set to (0, (1 / 2). H).
[0069] Optionally, such as Figure 6 As shown, the coordinates of the overlapping position of two adjacent lenses 20A1 are set to (0, (4 / 5). H) helps to avoid the overlapping position of two adjacent lenses 20A1 being too high, causing the part between two adjacent lenses 20A1 to be close to the plane. This helps to avoid the position between two adjacent lenses 20A1 having a good effect on changing the light path and ensuring the light processing capability of lens group 20A.
[0070] Figure 7 Another method provided for embodiments of this application is along Figure 1 A cross-sectional view along the A-A' direction.
[0071] In one embodiment of this application, such as Figure 7 As shown, along the adjacent direction of two adjacent lenses 20A1, the maximum width of lens 20A1 is D, and the maximum width of the overlapping part 20A2 of two adjacent lenses 20A1 along the adjacent direction of two adjacent lenses 20A1 is D2, 0≤D2≤(4 / 5). D.
[0072] In this embodiment, setting the width D2 of the overlap 20A2 between two adjacent lenses 20A1 within a preset range is beneficial for providing a feasible solution for this embodiment. It also helps avoid gaps between adjacent lenses 20A1, thus ensuring that the lens group 20A completely covers the sub-pixel 30A. Furthermore, the overlap 20A2 between adjacent lenses 20A improves the light processing effect of the lens group 20A, ensuring that light emitted from the edge of the lens 20A1 still has a noticeably altered light path, thereby improving the privacy protection effect of the display panel 100.
[0073] Figure 8 This is a planar schematic diagram of a lens assembly provided in an embodiment of this application. Figure 9 This is a planar schematic diagram of another lens assembly provided in an embodiment of this application.
[0074] In one embodiment of this application, combined with Figure 1 , Figure 8 , Figure 9 As shown, the lens group 20A includes multiple lenses 20A1 arranged along the first direction X1 and / or along the second direction X2. In this embodiment, one lens group 20A corresponds to one sub-pixel as an example for illustration.
[0075] Optionally, such as Figure 8 As shown, the lens group 20A includes multiple lenses 20A1 arranged along the first direction X1. Based on the above embodiment, it can be seen that the extension lengths of the lens group 20A in both the first direction X1 and the second direction X2 are greater than the extension lengths of the sub-pixel 30 in both directions X1 and X2. Therefore, when multiple lenses 20A1 are arranged along the first direction X1, the diameter of the lens 20A1 in the second direction X2 can be set to be greater than the extension length of the sub-pixel 30A in the second direction X2.
[0076] Optionally, such as Figure 9 As shown, the lens group 20A includes multiple lenses 20A1 arranged along the second direction X2. Based on the above, it can be seen that the diameter of the lens 20A1 in the first direction X1 can be set to be greater than the extension length of the sub-pixel 30 in the first direction X1.
[0077] Optionally, continue to refer to Figure 1As shown, the lens group 20A includes multiple lenses 20A1 arranged along the first direction X1 and the second direction X2. This allows for more flexible adjustment of the fabrication position of each lens 20A1 in the lens group 20A according to the size of the sub-pixel 30A, so that the lens group 20A can better cover the sub-pixel 30.
[0078] In one embodiment of this application, reference continues to be made to... Figure 1 , Figure 2 As shown, lens group 20A includes a first type lens group 20AA, which includes multiple first type lenses 20AA1. Sub-pixel 30A includes first type sub-pixels 30A1, and the first type lens group 20AA and the first type sub-pixels 30A1 overlap. In this embodiment, the first type lens group 20AA is configured to process the emitted light from the first type sub-pixels 30A1, thereby changing the light path of the emitted light from the first type sub-pixels 30A1 through the first type lenses 20AA1.
[0079] The surface of the first type of lens 20AA1 away from the substrate 10 is curved in the first direction X1, and the surface of the first type of lens 20AA1 away from the substrate 10 is also curved in the second direction X2, so that the first type of lens 20AA1 is a convex lens and its surface has a focusing effect on light in multiple directions, which is beneficial to realizing the privacy function of the lens layer 20.
[0080] In one embodiment of this application, reference is made to Figure 2 As shown, having multiple identical first-type lenses 20AA1 within the same first-type lens group 20AA helps to unify the light processing effect of each first-type lens 20AA1, improves the uniformity of light emitted from various positions within the first-type lens group 20AA, and enhances the display effect. Furthermore, the identical structure of multiple first-type lenses 20AA1 within the same first-type lens group 20AA reduces the difficulty of manufacturing the first-type lens group 20AA and increases its manufacturing efficiency.
[0081] Figure 10 This is a plan view of yet another display panel provided in an embodiment of this application. Figure 11 An embodiment provided in this application Figure 10 A cross-sectional view along the B-B' direction.
[0082] In one embodiment of this application, combined with Figure 10 , Figure 11As shown, by setting at least some of the first-type lenses 20AA1 in the same first-type lens group 20AA to have different structures, it is beneficial to adjust the light emission path more flexibly by cooperating with the first-type lenses 20AA1 with different structures; and it is also beneficial to achieve different processing effects for light emitted from different positions, and to adjust the light emission path more precisely, thereby improving the light processing effect of the lens layer 20. Optionally, as Figure 10 As shown, at least some of the first-class lenses 20AA1 in the same first-class lens group 20AA have different diameters.
[0083] In one embodiment of this application, reference continues to be made to... Figure 10 , Figure 11 As shown, in the same first type lens group 20AA, the diameter of the first type lens 20AA1 near the edge of the first type sub-pixel 30A1 is larger than the diameter of the first type lens 20AA1 away from the edge of the first type sub-pixel 30A1. When the first type sub-pixel 30A1 emits light, some of the light rays have a larger emission angle, which is not conducive to achieving privacy protection for the display panel 100.
[0084] In this embodiment, the diameter of the first-type lens 20AA1 near the edge of the first-type sub-pixel 30A1 is larger than the diameter of the first-type lens 20AA1 away from the edge of the first-type sub-pixel 30A1. This improves the coverage of the first-type lens group 20AA over the edge of the first-type sub-pixel 30A1, ensuring that light rays with larger emission angles can also pass through the first-type lens 20AA1, and alters the optical path, reducing the emission angle of the light. Furthermore, the larger diameter of the first-type lens 20AA1 near the edge of the first-type sub-pixel 30A1 enhances the ability of the first-type lens 20AA1 near the edge of the first-type sub-pixel 30A1 to focus light, thereby improving the focusing effect of the first-type lens group 20AA.
[0085] Figure 12 An embodiment provided in this application Figure 10 A cross-sectional view along the B-B' direction.
[0086] In one embodiment of this application, combined with Figure 10 , Figure 12 As shown, in the same first type lens group 20AA, the thickness of the first type lens 20AA1 near the edge of the first type sub-pixel 30A1 in the plane direction perpendicular to the display panel 100 is greater than the thickness of the first type lens 20AA1 far from the edge of the first type sub-pixel 30A1 in the plane direction perpendicular to the display panel 100.
[0087] In this embodiment, the first type lens 20AA1 near the edge of the first type sub-pixel 30A1 is made thicker in the direction perpendicular to the plane of the display panel 100. This is beneficial because, in addition to focusing the light, the first type lens 20AA1 located at the edge of the first type sub-pixel 30A1 can also block some light rays with a large emission angle. This allows the light rays with a large emission angle to pass through the first type lens 20AA1 located at the edge of the first type sub-pixel 30A1 again, thereby achieving secondary focusing.
[0088] Figure 13 This is a plan view of yet another display panel provided in an embodiment of this application. Figure 14 An embodiment provided in this application Figure 13 A cross-sectional view along the C-C' direction.
[0089] In one embodiment of this application, combined with Figure 13 , Figure 14 As shown, the plurality of first-class sub-pixels 30A1 include first-class first-color sub-pixels 30A11, first-class second-color sub-pixels 30A12, and first-class third-color sub-pixels 30A13. Optionally, the first-class first-color sub-pixels 30A11, first-class second-color sub-pixels 30A12, and first-class third-color sub-pixels 30A13 proposed in the embodiments of this application are respectively red sub-pixels, green sub-pixels, and blue sub-pixels.
[0090] The first lens group 20AA, which at least partially overlaps with the first-color sub-pixel 30A11, includes multiple first-color first lenses 20AA11; the first lens group 20AA, which at least partially overlaps with the second-color sub-pixel 30A12, includes multiple second-color first lenses 20AA12; and the first lens group 20AA, which at least partially overlaps with the third-color sub-pixel 30A13, includes multiple third-color first lenses 20AA13. This ensures that the light emitted from all three color sub-pixels can pass through the lenses before being emitted, which helps to guarantee the overall privacy protection effect of the display panel 100.
[0091] In this embodiment, the first type of first lens 20AA11, the first type of second lens 20AA12, and the first type of third lens 20AA13 are structurally identical, which helps to reduce the difficulty of fabricating the lens 20A1 in the lens layer 20 and improve the fabrication efficiency of multiple lenses 20A1. Furthermore, setting the lens types covering different color sub-pixels to have the same structure helps to improve the light path processing effect of the first type of first lens 20AA11, the first type of second lens 20AA12, and the first type of third lens 20AA13 on the three color sub-pixels 30A1 respectively, improving the display uniformity of the display panel 100 including the lens layer 20, thereby improving the display effect of the display panel 100.
[0092] Figure 15 This is a plan view of yet another display panel provided in an embodiment of this application. Figure 16 An embodiment provided in this application Figure 15 A cross-sectional view along the D-D' direction.
[0093] In one embodiment of this application, combined with Figure 15 , Figure 16 As shown, the plurality of first-type sub-pixels 30A1 include first-type first-color sub-pixels 30A11, first-type second-color sub-pixels 30A12, and first-type third-color sub-pixels 30A13. Optionally, the first-type first-color sub-pixels 30A11, first-type second-color sub-pixels 30A12, and first-type third-color sub-pixels 30A13 proposed in this application embodiment are red sub-pixels, green sub-pixels, and blue sub-pixels, respectively. The first-type lens group 20AA, which at least partially overlaps with the first-type first-color sub-pixels 30A11, includes a plurality of first-type first lenses 20AA11; the first-type lens group 20AA, which at least partially overlaps with the first-type second-color sub-pixels 30A12, includes a plurality of first-type second lenses 20AA12; and the first-type lens group 20AA, which at least partially overlaps with the first-type third-color sub-pixels 30A13, includes a plurality of first-type third lenses 20AA13.
[0094] In this embodiment, the structures of the first type first lens 20AA11, the first type second lens 20AA12, and the first type third lens 20AA13 are different. It is understood that the light-emitting areas of the first type first color sub-pixel 30A11, the first type second color sub-pixel 30A12, and the first type third color sub-pixel 30A13 in the display panel 100 can be different. Therefore, when fabricating the lens 20A1 on the corresponding color sub-pixel 30A11, the structures of the first type first lens 20AA11, the first type second lens 20AA12, and the first type third lens 20AA13 can be adaptively set according to the size of the different color sub-pixels 30A11, improving the light path processing effect of the first type first lens 20AA11, the first type second lens 20AA12, and the first type third lens 20AA13 on the first type first color sub-pixel 30A11, the first type second color sub-pixel 30A12, and the first type third color sub-pixel 30A13, respectively.
[0095] Optionally, such as Figure 15 , Figure 16 As shown, the first type of third color sub-pixel 30A13 has a larger light-emitting area than the first type of first color sub-pixel 30A11, the first type of second color sub-pixel 30A12, and the first type of third color sub-pixel 30A13, which can adaptably increase the diameter of the first type of third lens 20AA13.
[0096] Figure 17 This is a plan view of yet another display panel provided in an embodiment of this application. Figure 18 An embodiment provided in this application Figure 17 A cross-sectional view along the E-E' direction. Figure 19 This is a plan view of yet another display panel provided in an embodiment of this application. Figure 20 A method provided for this application Figure 19 A cross-sectional view along the F-F' direction.
[0097] In one embodiment of this application, combined with Figures 17-20 As shown, the lens group 20A in the display panel 100 also includes a second type of lens group 20AB, which includes at least one second type of lens 20AB1.
[0098] Continue to refer to Figure 17 , Figure 19 As shown, sub-pixel 30A also includes a second type of sub-pixel 30A2, and the second type of lens group 20AB overlaps with the second type of sub-pixel 30A2.
[0099] Optionally, such as Figure 17 , Figure 18As shown, the lens group 20A included in the display panel 100 is a second type of lens group 20AB, and the second type of lens group 20AB covers the second type of sub-pixel 30A2.
[0100] Optionally, such as Figure 19 , Figure 20 As shown, the display panel 100 includes a first type of lens group 20AA and a second type of lens group 20AB, and the first type of lens group 20AA covers the first type of sub-pixel 30A1, and the second type of sub-pixel 20AB covers the second type of sub-pixel 30A2.
[0101] In the embodiments of this application, such as Figure 17 As shown, the lens group 20A in the display panel 100 also includes a second type of lens group 20AB. The second type of lens 20AB1 in the second type of lens group 20AB includes at least a first portion 20AB11. The surface of the first portion 20AB11 away from the substrate 10 extends along the first direction X1. This facilitates the inclusion of different types of lenses 20A in the display panel 100, thereby enabling the display panel 100 to adapt to changes in the light path under different usage scenarios. Furthermore, since the first portion 20AB11 of the second type of lens 20AB1 extends along the first direction X1, it is possible that the light emitted from the light-emitting layer in the first direction X1 will not have its light path altered, making the second type of lens 20AB1 suitable for scenarios requiring specific light processing.
[0102] Or, such as Figure 19 As shown, the display panel 100 includes a first type of lens group 20A1 and a second type of lens group 20B. The second type of lens 20AB1 in the second type of lens group 20AB includes at least a first portion 20AB11, the surface of which the first portion 20AB11 extends away from the substrate 10 along a first direction X1. The display panel 100 also includes a first type of sub-pixel 30A1 and a second type of sub-pixel 30A2. This allows for different light path processing effects from different sub-pixels 30A in the display panel 100 using different lens groups, making the display panel 100 suitable for more application scenarios. For example, when the display panel 100 requires high privacy protection, the first type of sub-pixel 30A1 is used for display. In this case, the first type of lens group 20A1 can produce a good focusing effect on the light emitted from the first type of sub-pixel 30A1. When the privacy protection conditions of the display panel 100 are not strict, the second type of sub-pixel 30A2 display can be used. At this time, the second type of lens group 20B can selectively focus the light emitted from the second type of sub-pixel 30B, thereby making the privacy protection direction of the display panel 100 adjustable.
[0103] Figure 21 This is a plan view of another display panel provided in an embodiment of this application.
[0104] In one embodiment of this application, such as Figure 21 As shown, the first portion 20AB11 of the second type lens 20AB1 extends along the second direction X2 on the surface away from the substrate 10. Optionally, the first portion 20AB11 of the second type lens 20AB1 extends in a straight line along the first direction X1 and also in a straight line along the second direction X2, which is beneficial to make the surface of the second type lens 20AB1 away from the substrate 10 planar. This application embodiment uses a display panel 100 including a first type sub-pixel 30A1 and a second type sub-pixel 30A2 as an example for illustration.
[0105] As can be seen from the above embodiments, the surface of the first type of sub-pixel 30A1 is covered by the first type of lens group 20AA, and the surface of the first type of lens 20AA1 in the first type of lens group 20AA extends along the first direction X1 and the second direction X2, so that when the first type of sub-pixel 30A1 is displayed, the light emitted by the first type of sub-pixel 30A1 can be focused, so that when the display panel 100 needs to enter the privacy mode, the first type of sub-pixel 30A1 can be selected to work.
[0106] In this embodiment, the display panel 100 further includes a second type of sub-pixel 30A2. The surface of the second type of lens 20AB1 covering the surface of the second type of sub-pixel 30A2 extends linearly along a first direction X1 and a second direction X2. This allows the surface of the second type of sub-pixel 30A2 to also be covered with a lens, but selectively alters the optical path of the light emitted from the second type of sub-pixel 30A2. This technical solution allows the display panel 100 to be used in situations where there is no privacy protection or only a targeted privacy protection direction, in which case the second type of sub-pixel 30A2 can operate. Furthermore, after providing a lens covering the surface of the first type of sub-pixel 30A1 in the display panel 100, a lens is also correspondingly prepared on the surface of the second type of sub-pixel 30A2. This improves the structural regularity of the display panel 100 and, when the first type of sub-pixel 20A1 and the second type of sub-pixel 30A2 operate simultaneously, reduces the difference in light output brightness between the two, improving the display effect of the display panel 100.
[0107] In one embodiment of this application, reference continues to be made to... Figure 17 , Figure 19As shown, the surface of the first portion 20AB11 of the second type lens 20AB1, away from the substrate 10, is curved in the second direction X2. Furthermore, the curved surface of the first portion 20AB11 of the second type lens 20AB1, away from the substrate 10, convexes towards the light-emitting surface of the display panel 100 in the second direction X2. Considering that the surface of the first portion 20AB11 extends in the first direction X1, it can be seen that the first portion 20AB11 of the second type lens 20AB1 can focus the light emitted from the second type sub-pixel 30A2 in the second direction X2.
[0108] In this embodiment, the surface of the first portion 20AB11 of the second type lens 20AB1, away from the substrate 10, is curved in the second direction X2. This allows the second type lens 20AB1 to change the optical path of the light emitted from the second type sub-pixel 30A2 in the second direction X2. This enables the second type sub-pixel 30A2 of the display panel 100 to focus the light scattered in the second direction X2 as much as possible when it is working, making it easier to apply the display panel 100 in targeted privacy scenarios. For example, when the display panel 100 is used in the automotive display field, if it is located near the windshield in the second direction X2, some of the light emitted by the display panel 100 will be projected onto the windshield, potentially affecting the driver's ability to observe road conditions. Therefore, this embodiment uses the surface of the second type sub-pixel 30A2 to cover the second type lens 20AB1. This prevents the light emitted from the second type sub-pixel 30A2 from being projected onto the windshield in the second direction X2, thereby improving the clarity of the driver's view of road conditions and enhancing driving safety.
[0109] Figure 22 An embodiment provided in this application Figure 19 The projection view of the second type of lens in the image.
[0110] In one embodiment of this application, combined with Figure 19 , Figure 22 As shown, the projected area of the first portion 20AB11 of the second type lens 20AB1 in the first direction X1 is different from the projected area of the first portion 20AB11 in the second direction X2. In conjunction with the above embodiments, it can be seen that the curved surface extending along the first direction X1 and along the second direction X2 of the first portion 20AB11 is a surface, and the second type lens 20AB1 can be configured as a columnar structure with a curved surface away from the substrate 10.
[0111] like Figure 22 As shown in Figure (a), the projection shape of the first part 20AB11 of the second type lens 20AB1 in the first direction X1 is fan-shaped, as shown in Figure (a). Figure 22As shown in Figure (b), the projection shape of the first part 20AB11 of the second type lens 20AB1 in the second direction X2 is rectangular.
[0112] Figure 23 This is a plan view of yet another display panel provided in an embodiment of this application. Figure 24 An embodiment provided in this application Figure 23 A cross-sectional view along the G-G' direction.
[0113] In one embodiment of this application, combined with Figure 23 , Figure 24 As shown, the second type lens 20AB1 also includes a second portion 20AB12. Optionally, the first portion 20AB11 and the second portion 20AB12 of the second type lens 20AB1 are continuous structures. Along the first direction X1, the second portion 20AB12 is located on the side of the first portion 20AB11 near at least one edge of the second type lens 20AB1. That is, the second portion 20AB12 of the second type lens 20AB1 is located at the edge portion of the second type lens 20AB1.
[0114] In this embodiment, the surface of the second portion 20AB12 away from the substrate 10 is curved in the first direction X1. This allows the light emitted from the second portion 20AB12 toward the edge of the second type of sub-pixel 30A2 to have its optical path altered, reducing the scattered light from the edge portion of the second type of sub-pixel 30A2 in the first direction X1. This ensures that both the first type of sub-pixel 30A1 and the second type of sub-pixel 30A2 in the display panel 100 can be displayed using the second portion 20AB12, providing a privacy protection effect in the first direction X1. Furthermore, when the display panel 100 includes the first type of sub-pixel 30A1 and the second type of sub-pixel 30A2, optionally, the first type of sub-pixel 30A1 and the second type of sub-pixel 30A2 are adjacent in the first direction X1. This helps prevent the emitted light from the second type of sub-pixel 30A2 from affecting the emitted light from the first type of sub-pixel 30A1, and also helps prevent crosstalk between the first type of sub-pixel 30A1 and the second type of sub-pixel 30A2, improving the display effect of the display panel 100.
[0115] Figure 25 This is a planar schematic diagram of a second type of lens group provided in an embodiment of this application. Figure 26 This is a plan view of yet another type of second lens group provided in an embodiment of this application. Figure 27 This is a planar schematic diagram of another type of lens group provided in an embodiment of this application.
[0116] In one embodiment of this application, combined with Figures 25-27As shown, the second type lens group 20AB includes at least two second type lenses 20AB1. The second type lenses 20AB1 in the same second type lens group 20AB are arranged along a first direction X1, and / or, the second type lenses 20AB1 in the same second type lens group 20AB are arranged along a second direction X2. This embodiment of the application uses one second type lens group 20AB covering one second type sub-pixel 30A2 as an example for illustration. In this embodiment, setting the number of second type lenses 20AB1 in the second type lens group 20AB to be greater than or equal to 2 is beneficial for increasing the number of second type lenses 20AB1 in the same second type lens group 20AB, thereby reducing the size of a single second type lens 20AB1 and avoiding the risk of increasing the thickness of the display panel 100 due to a large height of the second type lens group 20AB. Furthermore, setting multiple second type lenses 20AB1 facilitates the flexible alteration of the light path through the cooperation of multiple second type lenses 20AB1.
[0117] In one embodiment of this application, reference is made to Figures 25-27 As shown, the multiple second-type lenses 20AB1 in the same second-type lens group 20AB have the same structure, which helps to reduce the difficulty of manufacturing multiple second-type lenses 20AB1, thereby improving the working efficiency of manufacturing second-type lenses 20AB1, and thus improving the manufacturing efficiency of display panel 100.
[0118] Figure 28 An embodiment provided in this application Figure 19 A cross-sectional view along the H-H' direction.
[0119] In one embodiment of this application, combined with Figure 19 , 28 As shown, at least some of the second-type lenses 20AB1 in the same second-type lens group 20AB have different structures. Optionally, the height of the second-type lens 20AB1 located at the edge of the second-type lens group 20AB is greater than the height of the second-type lens 20AB1 located in the middle part of the second-type lens group 20AB.
[0120] In this embodiment, setting at least some of the second-type lenses 20AB1 in the same second-type lens group 20AB to have different structures is beneficial to improving the structural diversity of the second-type lenses 20AB1. The second-type lenses 20AB1 with different structures have different focusing capabilities for light. Therefore, the emitted light of the second-type sub-pixel 30A2 processed by the second-type lenses 20AB1 with different structures is beneficial to improving the accuracy of the second-type lens group 20AB in changing the optical path of the emitted light of the second-type sub-pixel 30A2, thereby improving the privacy performance of the display panel 100.
[0121] Figure 29A flowchart illustrating the working mode of a display panel provided in an embodiment of this application.
[0122] In one embodiment of this application, such as Figure 29 As shown, the display panel 100 includes a first operating mode M1 and a second operating mode M2. When the display panel 100 is in the first operating mode M1, the first type of sub-pixel 30A1 is turned on and the second type of sub-pixel 30A2 is turned off. When the display panel 100 is in the second operating mode M2, both the first type of sub-pixel 30A1 and the second type of sub-pixel 30A2 are turned on. In this embodiment, the first operating mode M1 is a privacy mode and the second operating mode M2 is a non-privacy mode, as an example for explanation. When the display panel 100 is applied in the automotive field, it can be applied to a passenger-side display screen. Optionally, when the display panel 100 is operating in the first operating mode M1, corresponding to the vehicle being in motion, from the driver's perspective, it is not easy to receive the light emitted by the first type of sub-pixel 30A1. When the display panel 100 is operating in the second operating mode M2, corresponding to the vehicle not being in motion, from the driver's perspective, it is easier to receive the light emitted by the display panel 100.
[0123] In this embodiment, when the display panel 100 is in the first working mode M1, the first type of sub-pixel 30A1 is turned on. At this time, the light emitted from the first type of sub-pixel 30A1 can be focused by the first type of lens 20AA, allowing the display content of the display panel 100 to be clearly viewed by the passenger, making it less likely for the driver to observe the display content. This helps reduce the impact of the display panel 100 on the driver, thereby reducing the risk of distracting the driver and improving vehicle safety. When the display panel 100 is in the second working mode M2, both the first type of sub-pixel 30A1 and the second type of sub-pixel 30A2 are turned on, which increases the number of pixels on the display panel 100 during operation, thereby improving the display effect of the display panel 100 and enhancing the viewing experience for the driver at a wide viewing angle.
[0124] Figure 30 A flowchart illustrating the working mode of another display panel provided in this application embodiment.
[0125] In one embodiment of this application, such as Figure 30 As shown, the display panel 100 is configured to include a first working mode M1 and a second working mode M2. When the display panel 100 is in the first working mode M1, the first type of sub-pixel 30A1 is turned on and the second type of sub-pixel 30A2 is turned off. And when the display panel 100 is in the second working mode M2, the first type of sub-pixel 30A1 is turned off and the second type of sub-pixel 30A2 is turned on.
[0126] In this embodiment, the description is based on the example of a first working mode M1 being a privacy mode and a second working mode M2 being a non-privacy mode. When the display panel 100 is applied in the automotive field, it can be used as a passenger-side display screen. Optionally, when the display panel 100 is operating in the first working mode M1, corresponding to the vehicle being in motion, the driver's perspective makes it difficult to receive the light emitted from the first type of sub-pixel 30A1. When the display panel 100 is operating in the second working mode M2, corresponding to the vehicle not being in motion, the driver's perspective makes it easier to receive the light emitted from the display panel 100.
[0127] In this embodiment, when the display panel 100 is in the first working mode M1, the first type of sub-pixel 30A1 is turned on. At this time, the light emitted from the first type of sub-pixel 30A1 can be focused by the first type of lens 20AA, allowing the display content of the display panel 100 to be clearly viewed by the passenger, making it difficult for the person in the driver's seat to observe the display content. This helps reduce the impact of the display panel 100 on the driver, thereby reducing the risk of distracting the driver and improving vehicle safety. When the display panel 100 is in the second working mode M2, the first type of sub-pixel 30A1 is turned off and the second type of sub-pixel 30A2 is turned on. This allows the second type of sub-pixel 30A2, which has a weaker anti-peeping effect on the driver's seat, to be turned on, allowing the person in the driver's seat to view the display panel 100 normally. Furthermore, setting only one type of sub-pixel 30A to be turned on in a single working mode helps reduce the energy consumption of the display panel 100.
[0128] Figure 31 This is a schematic diagram of a pixel circuit provided in an embodiment of this application.
[0129] In one embodiment of this application, the display panel 100 further includes a pixel circuit 50 located on the side of the light-emitting layer 30 facing the substrate 10. The pixel circuit 50 is used to generate a light-emitting driving current and transmit the light-emitting driving current to the sub-pixel 30A located in the light-emitting layer 30, thereby driving the sub-pixel 30A to emit light.
[0130] like Figure 31 As shown, the same pixel circuit 50 is electrically connected to the first type of sub-pixel 30A1 and the second type of sub-pixel 30A2. This allows the pixel circuit 50 to simultaneously control both the first type of sub-pixel 30A1 and the second type of sub-pixel 30A2, which helps reduce the number of pixel circuits 50 and thus improves the thinness and lightness of the display panel 100. Optionally, the first type of sub-pixel 30A1 and the second type of sub-pixel 30A2 electrically connected to the same pixel circuit 50 have the same emission color.
[0131] The pixel circuit 50 includes a first light-emitting control module 50A, a second light-emitting control module 50B, and a third light-emitting control module 50C. The control terminal of the first light-emitting control module 50A is electrically connected to the first light-emitting signal line E1, its first terminal is electrically connected to the first power supply voltage PVDD, and its second terminal is electrically connected to the first terminal of the second light-emitting control module 50B. When the first light-emitting signal line E1 transmits a valid signal, the pixel circuit 50 operates in the light-emitting stage. At this time, the first power supply voltage PVDD drives the pixel circuit 50 to operate, transmitting the first power supply voltage PVDD to the first light-emitting control module 50A. The first light-emitting control module 50A transmits the received first power supply voltage PVDD to the driving transistor Md, which generates a light-emitting driving current. The light-emitting driving current generated by the driving transistor Md then flows to either the first type of sub-pixel 30A1 or the second type of sub-pixel 30A2.
[0132] The control terminal of the second light-emitting control module 50B in the pixel circuit 50 is also electrically connected to the first light-emitting signal line E1, and the second terminal is electrically connected to the first type of sub-pixel 30A1. The control terminal of the third light-emitting control module 50C is electrically connected to the second light-emitting signal line E2, the first terminal is electrically connected to the second terminal of the first light-emitting control module 50A, and the second terminal is electrically connected to the second type of sub-pixel 30A2.
[0133] In this embodiment, when the display panel 100 is in the first operating mode M1, the first light-emitting signal line E1 transmits a valid signal to control the first light-emitting control module 50A and the second light-emitting control module 50B to turn on, and the second light-emitting signal line E2 transmits an invalid signal to control the third light-emitting control module 50C to turn off. When the display panel 100 is in the second operating mode M2, both the first light-emitting signal line E1 and the second light-emitting signal line E2 transmit valid signals, and all three light-emitting control modules 50A, 50B, and 50C are turned on. This facilitates the display panel 100 controlling the first type of sub-pixel 30A1 to turn on and the second type of sub-pixel 30A2 to turn off in the first operating mode M1, and the display panel 100 controlling both the first type of sub-pixel 30A and the second type of sub-pixel 30B to turn on in the second operating mode M2.
[0134] In addition, such as Figure 31 As shown, the pixel circuit 50 provided in this embodiment further includes:
[0135] The data writing module 50D receives the data voltage Vdata and transmits it to the driving transistor Md. The transmitted value of the data voltage Vdata is related to the brightness of the first type of sub-pixel 30A1 and the second type of sub-pixel 30A2.
[0136] The first reset module 50E is used to reset the gate of the driving transistor Md before the driving transistor Md receives the data voltage, and transmits the first reset voltage Vref1 to the gate of the driving transistor Md to ensure the accuracy of the light-emitting driving current generated by the driving transistor Md.
[0137] The threshold writing module 50F is used to compensate the threshold voltage of the driving transistor Md to the gate of the driving transistor Md.
[0138] The second reset module 50G is used to reset the first type of sub-pixel 30A1 before it receives the light-emitting driving current, and transmits the second reset voltage Vref2 to the first pole of the first type of sub-pixel 30A1 to ensure the accuracy of the light-emitting brightness of the first type of sub-pixel 30A1.
[0139] The third reset module 50H is used to reset the second type sub-pixel 30A2 before it receives the light-emitting driving current. It transmits the third reset voltage Vref3 to the first electrode of the second type sub-pixel 30A2 to ensure the accuracy of the light-emitting brightness of the second type sub-pixel 30A2.
[0140] Figure 32 This is a schematic diagram of another pixel circuit provided in an embodiment of this application.
[0141] In one embodiment of this application, such as Figure 32 As shown, the display panel 100 also includes a pixel circuit 50, which is located on the side of the light-emitting layer 30 facing the substrate 10. The same pixel circuit 50 is electrically connected to both the first type of sub-pixel 30A1 and the second type of sub-pixel 30A2. The pixel circuit 50 includes a first light-emitting control module 50A, a second light-emitting control module 50B, and a third light-emitting control module 50C. The control terminal of the first light-emitting control module 50A is electrically connected to the first light-emitting signal line E1, its first terminal is electrically connected to the first power supply voltage PVDD, and its second terminal is electrically connected to the first terminal of the second light-emitting control module 50B. The control terminal of the second light-emitting control module 50B is electrically connected to the third light-emitting signal line E3, and its second terminal is electrically connected to the first type of sub-pixel 30A1. The control terminal of the third light-emitting control module 50C is electrically connected to the second light-emitting signal line E2, its first terminal is electrically connected to the second terminal of the first light-emitting control module 50A, and its second terminal is electrically connected to the second type of sub-pixel 30A2. In the pixel circuit 50, the first light-emitting signal line E1, the second light-emitting signal line E2, and the third light-emitting signal line E3 are set to control the first light-emitting control module 50A, the second light-emitting control module 50B, and the third light-emitting control module 50C, respectively. This helps to improve the accuracy of controlling the switches of each module in the pixel circuit 50 and to control the working state of different light-emitting modules more flexibly.
[0142] Optionally, the first type of sub-pixel 30A1 and the second type of sub-pixel 30A2, which are electrically connected simultaneously by the same pixel circuit 50, emit the same color.
[0143] In this embodiment, when the display panel 100 is in the first operating mode M1, the first light-emitting signal line E1 transmits a valid signal to control the first light-emitting control module 50A to turn on, the third light-emitting signal line E3 transmits a valid signal to control the second light-emitting control module 50B to turn on, and the second light-emitting signal line E2 transmits an invalid signal to control the third light-emitting control module 50C to turn off. When the display panel 100 is in the second operating mode M2, the first light-emitting signal line E1 transmits a valid signal, the second light-emitting signal line E2 transmits a valid signal, and the third light-emitting signal line E3 also transmits a valid signal, and the first light-emitting control module 50A, the second light-emitting control module 50B, and the third light-emitting control module 50C are all turned on. This is beneficial for the display panel 100 to control the first type of sub-pixel 30A1 to turn on and the second type of sub-pixel 30A2 to turn off in the first operating mode M1, and to control both the first type of sub-pixel 30A1 and the second type of sub-pixel 30A2 to turn on in the second operating mode M2.
[0144] Alternatively, when the display panel 100 is in the second operating mode M2, the first light-emitting signal line E1 transmits a valid signal, the second light-emitting signal line E2 transmits a valid signal, and the third light-emitting signal line E3 transmits a non-valid signal. The first light-emitting control module 50A and the third light-emitting control module 50C are turned on, and the second light-emitting control module 50B is turned off. This is beneficial for the display panel 100 to control the first type of sub-pixel 30A1 to be turned on and the second type of sub-pixel 30A2 to be turned off in the first operating mode M1, and can also control the display panel 100 to control the first type of sub-pixel 30A1 to be turned off and only the second type of sub-pixel 30A2 to be turned on in the second operating mode M2.
[0145] In one embodiment of this application, reference continues to be made to... Figure 19As shown, along the first direction X1, first-type sub-pixels 30A1 and second-type sub-pixels 30A2 are arranged alternately. This alternating arrangement of the first-type sub-pixels 30A1 (which offer stronger privacy protection) and the second-type sub-pixels 30A2 (which offer weaker privacy protection) along the first direction X1 in the display panel 100 helps to achieve a more uniform distribution of the first-type sub-pixels 30A1 and second-type sub-pixels 30A2, resulting in a more uniform display effect when the first-type sub-pixels 30A1 and second-type sub-pixels 30A2 are working separately, thus improving the working effect of the display panel 100. Furthermore, the alternating arrangement of the first-type sub-pixels 30A1 and second-type sub-pixels 30A2 allows the pixel circuit 50 to simultaneously control both types of sub-pixels 30A1 and 30A2. When the pixel circuit 50 is electrically connected to both types of sub-pixels 30A1 and 30A2 simultaneously, the wiring complexity between the pixel circuit 50 and either the first-type sub-pixels 30A1 or the second-type sub-pixels 30A2 is reduced.
[0146] Figure 33 This is a plan view of another display panel provided in an embodiment of this application.
[0147] In one embodiment of this application, such as Figure 33 As shown, along the second direction X2, the first type of sub-pixels 30A1 and the second type of sub-pixels 30A2 are arranged alternately. This alternating arrangement of the first type of sub-pixels 30A1 (which provides stronger privacy protection) and the second type of sub-pixels 30A2 (which provides weaker privacy protection) along the second direction X2 in the display panel 100 helps to achieve a more uniform distribution of the first type of sub-pixels 30A1 and the second type of sub-pixels 30A2, resulting in a more uniform display effect when the first type of sub-pixels 30A1 and the second type of sub-pixels 30A2 are working separately, thus improving the working effect of the display panel 100. Furthermore, the alternating arrangement of the first type of sub-pixels 30A1 and the second type of sub-pixels 30A2 along the second direction X2 helps to ensure that the distances of the first type of sub-pixels 30A1 and the second type of sub-pixels 30A2 from the edge of the display panel 100 along the first direction X1 are equal, which improves the viewing effect of the display panel 100 from the driver's position along the first direction X1.
[0148] Figure 34 This is a plan view of another display panel provided in an embodiment of this application.
[0149] In one embodiment of this application, such as Figure 34As shown, the light-emitting layer 30 includes a plurality of pixel units 30C arranged in an array. Each pixel unit 30C includes a first sub-pixel unit 30C1 and a second sub-pixel unit 30C2. The first sub-pixel unit 30C1 and the second sub-pixel unit 30C2 are arranged along a first direction X1. The first sub-pixel unit 30C1 includes a first type of first color sub-pixel 30A11, a second type of first color sub-pixel 30A21, a first type of second color sub-pixel 30A12, and a second type of second color sub-pixel 30A22 arranged sequentially along a second direction X2. The second sub-pixel unit 30C2 includes a first type of third color sub-pixel 30A13 and a second type of third color sub-pixel 30A23 arranged along a second direction X2.
[0150] like Figure 34 As shown, in this embodiment, the first type of first color sub-pixel 30A11, the first type of second color sub-pixel 30A12, the first type of third color sub-pixel 30A13, the second type of first color sub-pixel 30A21, the second type of second color sub-pixel 30A22, and the second type of third color sub-pixel 30A23 are located in the same pixel unit 30C. This makes the sub-pixel positions of each color more compact, which is beneficial to improving the white balance of each pixel unit 30C in the display panel 100 during display and reducing the circuit complexity of the pixel circuit 50 simultaneously connecting the first type of sub-pixel 30A1 and the second type of sub-pixel 30A2. Furthermore, by further improving the uniformity of the arrangement of the first type of sub-pixel 30A1 and the second type of sub-pixel 30A2, the display effect of the display panel 100 is improved.
[0151] Figure 35 This is a plan view of another display panel provided in an embodiment of this application.
[0152] In one embodiment of this application, such as Figure 35 As shown, the light-emitting layer 30 includes first-type pixel units A30 and second-type pixel units B30 arranged alternately along a first direction X1 and a second direction X2. The first-type pixel unit A30 includes multiple first-type sub-pixels 30A1 of different colors, and the second-type pixel unit B30 includes multiple second-type sub-pixels 30B of different colors.
[0153] In the embodiments of this application, the proposed alternating arrangement of the first type of pixel unit A30 and the second type of pixel unit B30 is beneficial to improving the arrangement diversity of the first type of sub-pixel 30A1 and the second type of sub-pixel 30B, which is beneficial to improving the applicability of the technical solution of this application and providing more ways to prepare the first type of sub-pixel 30A1 and the second type of sub-sub-pixel 30A2 in different application scenarios of display panel 100.
[0154] In one embodiment of this application, reference continues to be made to... Figure 34 , Figure 35As shown, the first type of sub-pixel 30A1 includes a first type of third color sub-pixel 30A13 and the second type of sub-pixel 30A2 includes a second type of third color sub-pixel 30A23. The first type of third color sub-pixel 30A13 and the second type of third color sub-pixel 30A23 are arranged alternately along the second direction X2.
[0155] In this embodiment, the spacing between adjacent first-type third-color sub-pixels 30A13 and second-type third-color sub-pixels 30A23 in the second direction X2 is the same. This is beneficial for achieving a more uniform distribution of the first-type third-color sub-pixels 30A13 and second-type third-color sub-pixels 30A23 fabricated on the display panel 100, and for improving the display effect when both the first-type third-color sub-pixels 30A13 and second-type third-color sub-pixels 30A23 are working. Furthermore, setting the spacing between the first-type third-color sub-pixels 30A13 and second-type third-color sub-pixels 30A23 to be the same helps to improve the structural regularity of the display panel 100 and reduce the fabrication difficulty of the display panel 100.
[0156] Figure 36 This is a plan view of yet another display panel provided in an embodiment of this application. Figure 37 This is a plan view of another display panel provided in an embodiment of this application.
[0157] In one embodiment of this application, such as Figure 36 , Figure 37 As shown, the first type of sub-pixel 30A1 includes a first type of third color sub-pixel 30A13 and the second type of sub-pixel 30A2 includes a second type of third color sub-pixel 30A23. The first type of third color sub-pixel 30A13 and the second type of third color sub-pixel 30A23 are arranged alternately along the second direction X2.
[0158] In this embodiment, the spacing between at least some of the adjacent first-type third-color sub-pixels 30A13 and second-type third-color sub-pixels 30A23 in the second direction X2 is different. This is beneficial for optimizing the color uniformity of the entire display panel 100 by adjusting the spacing between the first-type third-color sub-pixels 30A13 and second-type third-color sub-pixels 30B3. For example, when both the first-type third-color sub-pixels 30A13 and second-type third-color sub-pixels 30A23 are blue sub-pixels, excessively concentrated blue light may cause discomfort to the eyes. Increasing the spacing between the blue sub-pixels can reduce the concentration effect of blue light, making the color distribution more uniform, thereby reducing visual fatigue.
[0159] In one embodiment of this application, the lens 20A is either a plano-convex lens or a biconvex lens, which is beneficial for providing relevant technicians with a variety of selectable lens 20A structures and improving the applicability of the embodiments of this application.
[0160] Figure 38 Another embodiment provided in this application Figure 19 A cross-sectional view along the F-F' direction.
[0161] In one embodiment of this application, combined with Figure 19 , Figure 38 As shown, the display panel 100 also includes a cover plate 60, which is located on the side of the lens layer 20 facing the light-emitting surface of the display panel 100.
[0162] In this embodiment, the refractive index of the first type lens 20AA1 is set to be greater than that of the cover plate 60, and the refractive index of the second type lens 20AB1 is greater than that of the cover plate 60. This is beneficial to avoid the risk of a large degree of emission angle deviation after the light passing through the lens layer 20 passes through the cover plate 60, while protecting the display panel 100 with the cover plate 60. This improves the stability of the light emission angle after the lens layer 20 is processed, and ensures the privacy protection effect of the display panel 100.
[0163] Figure 39 This is a plan view of a display device provided in an embodiment of this application.
[0164] This application provides a display device 200, such as... Figure 39 As shown, the display device 200 includes a display panel 100 as provided in the above embodiments.
[0165] In the display device 200, the display panel 100 includes a lens layer 20, which facilitates the focusing of light emitted from the light-emitting layer 30 by the lens layer 20. This allows the display panel 100 to provide a privacy protection effect at a certain angle, increasing its applicability in the privacy protection field. Furthermore, including multiple lenses 20A1 in the same lens group 20A allows for the utilization of the combined effect of multiple lenses 20A1, making it possible to reduce the height of a single lens 20A1. This avoids the risk of compromising the thinness and lightness of the display panel 100 when only one lens 20A1 is included in the lens group 20A, which might require setting the lens 20A1 too high to improve its light processing effect. Moreover, the distribution of multiple smaller lenses 20A1 in the lens layer 20A not only improves the thinness and lightness of the display panel 100 when privacy protection is included, but also enhances the light processing effect of the lens layer 20A. By altering the optical path, it maximizes the uniformity of light distribution, improving the display effect of the display panel 100 and enhancing the user's visual experience. Furthermore, in this embodiment, the lens group 20A is set to cover the sub-pixel 30A, which is beneficial to ensure that all light emitted from the sub-pixel 30A toward the display panel 100 passes through the lens group 20A before being emitted, avoiding the omission of some light, which is beneficial to improving the light processing effect of the sub-pixel 30A and further improving the privacy performance of the display panel 100.
[0166] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
