Description

Technical Field

[0001] This application relates to the field of display technology, and more particularly to a display panel and display device. Background Technology

[0002] Today, consumers are significantly more aware of the privacy and security of display devices. In scenarios such as public transportation and workplaces, the risk of screen information being spied on by others is receiving increasing attention. Privacy protection displays have gradually transformed from high-end add-ons into essential features for the general public. People are no longer just pursuing display quality and a smooth experience; their demand for controllable viewing angles and side-view protection is growing stronger. The privacy protection effect directly affects the user's sense of security when using a display device and their purchasing decisions, and has also become an important indicator for measuring the overall competitiveness of display devices.

[0003] To achieve a privacy protection effect, privacy pixels need to be added. Since privacy pixels require additional area, the aperture ratio of the pixels decreases, which in turn reduces the lifespan of the pixels.

Detailed Implementation

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0024] An embodiment of this application provides a display panel, which includes normal pixels and privacy pixels. The normal pixels include a plurality of normal sub-pixels, each including a first normal sub-pixel that emits a first color light and a second normal sub-pixel that emits a second color light. The privacy pixels include a plurality of privacy sub-pixels, each including a first privacy sub-pixel that emits a first color light and a second privacy sub-pixel that emits a second color light. In adjacent normal pixels and privacy pixels, the extending direction of the line connecting the centers of the first normal sub-pixel and the adjacent first privacy sub-pixel intersects with the extending direction of the line connecting the centers of the second normal sub-pixel and the adjacent second privacy sub-pixel, and is perpendicular to the thickness direction of the display panel.

[0025] In the embodiments of this application, by making the extension direction of the line connecting the center of the first normal sub-pixel and the adjacent first privacy sub-pixel intersect with the extension direction of the line connecting the center of the second normal sub-pixel and the adjacent second privacy sub-pixel, the first privacy sub-pixel and the adjacent second privacy sub-pixel can be staggered while ensuring that the minimum spacing between the first privacy sub-pixel and the adjacent second privacy sub-pixel remains unchanged. This is beneficial to increase the area of ​​the normal pixel and / or the privacy pixel, thereby improving the lifespan of the normal pixel and / or the privacy pixel.

[0026] Please see Figure 1 , Figure 1 The above view is a top view of a display panel provided in an embodiment of this application. The display panel 100 has a display area AA, which is an area used to display a screen.

[0027] In some embodiments, such as Figure 1 As shown, the display panel 100 also includes a non-display area NA, which is located around the display area AA. The non-display area NA is an area for placing peripheral circuits, which may include, but are not limited to, gate drive circuits.

[0028] Please see Figure 2 and Figure 3 , Figure 2 An enlarged schematic diagram of point a in the first type of display panel provided for an embodiment of this application. Figure 3 This is a schematic diagram of a privacy pixel in a first type of display panel provided in an embodiment of the present application. The display panel 100 includes a plurality of normal pixels P1 and a plurality of privacy pixels P2. The normal pixels P1 include a plurality of normal sub-pixels SP1, which include a first normal sub-pixel SP11 that emits a first color light and a second normal sub-pixel SP12 that emits a second color light. The privacy pixels P2 include a plurality of privacy sub-pixels SP2, which include a first privacy pixel SP21 that emits a first color light and a second privacy pixel SP22 that emits a second color light.

[0029] In embodiments of this application, the first color light and the second color light are different colors, and are respectively one of red light, green light and blue light. For example, the first color light is blue light and the second color light is one of green light or red light; or, the first color light is green light and the second color light is one of red light or blue light; or, the first color light is red light and the second color light is one of green light or blue light.

[0030] In some embodiments, in adjacent normal pixels P1 and privacy pixels P2, the extension direction of the line connecting the center of the first normal sub-pixel SP11 and the adjacent first privacy sub-pixel SP21 intersects the extension direction of the line connecting the center of the second normal sub-pixel SP12 and the adjacent second privacy pixel SP22, and is perpendicular to the thickness direction of the display panel.

[0031] It should be noted that the centers of the first normal sub-pixel SP11, the first privacy sub-pixel SP21, the second normal sub-pixel SP12, and the second privacy sub-pixel SP22 are virtual and do not actually exist. For example, the center of the first normal sub-pixel SP11 refers to the geometric center of its orthographic projection onto the reference plane, and the center of the first privacy sub-pixel SP21 refers to its orthographic projection onto the reference plane. The centers of the other normal and privacy sub-pixels are similar, and will not be elaborated upon here.

[0032] Please see Figure 2 and Figure 3 In adjacent normal pixels P1 and privacy pixels P2, the center line connecting the first normal sub-pixel SP11 and the adjacent first privacy sub-pixel SP21 extends along the first direction D1, and the center line connecting the second normal sub-pixel SP12 and the adjacent second privacy pixel SP22 extends along the second direction D2. The first direction D1 and the second direction D2 intersect and are perpendicular to the thickness direction of the display panel.

[0033] By making the extension direction of the center line connecting the first normal sub-pixel SP11 and the adjacent first privacy sub-pixel SP21 different from the center line connecting the second normal sub-pixel SP12 and the adjacent second privacy sub-pixel SP22, the first privacy sub-pixel SP21 and the adjacent second privacy sub-pixel SP22 can be staggered while ensuring that the minimum spacing between the first privacy sub-pixel SP21 and the second privacy sub-pixel SP22 remains unchanged. This is beneficial to increase the area of ​​at least one of the first normal sub-pixel SP11, the first privacy sub-pixel SP21, the second normal sub-pixel SP12, and the second privacy sub-pixel SP22, thereby improving the lifespan of the normal pixel and / or the privacy pixel.

[0034] It should be noted that there is a correlation between the area of ​​a subpixel and its lifetime. The smaller the subpixel area, the faster its lifetime decays, resulting in a significant reduction in lifetime. Therefore, increasing the subpixel area is beneficial for improving the lifetime of the light-emitting part.

[0035] Please see Figure 2 and Figure 3 To achieve the privacy protection effect and due to manufacturing precision limitations, there is a minimum spacing between adjacent privacy sub-pixels; that is, the spacing between any two adjacent privacy sub-pixels must be greater than this minimum spacing. When two privacy sub-pixels are arranged along the row direction X, the spacing between them in the row direction X must be greater than or equal to the minimum spacing. When two privacy sub-pixels are staggered in the row direction X, the diagonal spacing between them must be greater than or equal to the minimum spacing. In this case, the spacing between them in the row direction X is reduced, and can be less than the minimum spacing. Therefore, the size occupied by two adjacent privacy sub-pixels in the row direction X can be reduced.

[0036] In some embodiments, the display panel 100 has a first display mode and a second display mode. In the first display mode, at least the normal pixel P1 emits light. In the second display mode, the normal pixel P1 does not emit light, while the privacy pixel P2 emits light.

[0037] In some embodiments, the first display mode is a non-peeping display mode, which does not have a peeping effect. In the first display mode, the normal pixel P1 emits light to display the image, while the peeping pixel P2 may or may not emit light. The second display mode is a peeping display mode, which has a peeping effect. In the second display mode, the normal pixel P1 does not emit light, while the peeping pixel P2 emits light. The maximum light emission angle of the peeping sub-pixel in the peeping pixel P2 is smaller than the maximum light emission angle of the normal sub-pixel in the normal pixel P1, thus reducing the light emission of the peeping pixel P2 from a side view, resulting in a darker image that is less likely to be observed by a bystander from a side view, thereby achieving the peeping display mode.

[0038] In some embodiments, please refer to Figure 4 The display panel includes an array substrate 2 and an anode layer, a pixel definition layer 3, a light-emitting layer 1, a common layer, a cathode layer, an encapsulation layer 4, a touch layer 5, at least one light-shielding layer 6, and at least one planarization layer 7 disposed on the array substrate 2.

[0039] In some embodiments, the pixel definition layer 3 has a plurality of pixel openings, and the anode layer includes a plurality of patterned anodes, each pixel opening exposing the anode located below.

[0040] In some embodiments, the film structure of both normal pixels and privacy pixels includes a hole injection layer, a hole transport layer, an electron transport layer, an electron injection layer, and a light-emitting layer that emits a corresponding color. The hole transport layer, hole injection layer, electron transport layer, and electron injection layer are film layers that cover the entire surface and can be shared by both normal pixels and privacy pixels; they can also be referred to as common layers. The light-emitting layer is a film layer in which light-emitting material is deposited into the corresponding pixel opening using a metal mask. In special cases, the light-emitting layer may be formed not only in the pixel opening but also in the area near the pixel opening.

[0041] In some embodiments, please refer to Figure 4 The encapsulation layer 4 is a thin-film encapsulation structure, which includes a first inorganic encapsulation layer 401, an organic encapsulation layer 402, and a second inorganic encapsulation layer 403 stacked sequentially.

[0042] In some embodiments, please refer to Figure 4 The touch layer 5 includes at least one touch metal layer and touch insulating layers disposed on the upper and lower sides of the touch metal layer. For example, the touch layer 5 includes a first touch insulating layer, a first touch metal layer, a second touch insulating layer, a second touch metal layer, and a third touch insulating layer stacked sequentially.

[0043] In some embodiments, the light-shielding layer 6 includes a plurality of light-shielding portions 61, the orthographic projection of each light-shielding portion 61 on the reference plane surrounds the orthographic projection of a corresponding privacy sub-pixel on the reference plane, so as to limit the large-angle light emission of the privacy sub-pixel.

[0044] In some embodiments, please refer to Figures 2 to 4 The orthographic projection of the light-shielding part 61 on the reference plane is a closed ring structure. The orthographic projection of each light-shielding part 61 on the reference plane completely surrounds the orthographic projection of the corresponding sub-pixel on the reference plane, so as to limit the large-angle light emitted by the anti-spy sub-pixel in all directions, thereby achieving a 360-degree anti-spy effect.

[0045] In some embodiments, please refer to Figure 4The display panel includes a multi-layer light-shielding layer 6 and a multi-layer planarization layer 7. The multi-layer light-shielding layer 6 includes a first light-shielding layer 601, a second light-shielding layer 602, and a third light-shielding layer 603. The multi-layer planarization layer 7 includes a first planarization layer 701, a second planarization layer 702, a third planarization layer 703, a fourth planarization layer 704, and a fifth planarization layer 705. The first light-shielding layer 601 is disposed on the touch layer 5. The first planarization layer 701 and the second planarization layer 702 are stacked sequentially on the touch layer 5 and the first light-shielding layer 601. The second light-shielding layer 602 is disposed on the second planarization layer 702. The third planarization layer 703 and the fourth planarization layer 704 are stacked sequentially on the second light-shielding layer 602 and the second planarization layer 702. The third light-shielding layer 603 is disposed on the fourth planarization layer 704. The fifth planarization layer 705 is disposed on the third light-shielding layer 603 and the fourth planarization layer 704. The first light-shielding layer 601, the second light-shielding layer 602, and the third light-shielding layer 603 are all provided with light-shielding parts 61 arranged around the sub-pixels. The light-shielding parts in the first light-shielding layer 601 overlap with the corresponding light-shielding parts in the second light-shielding layer 602 and the third light-shielding layer 603 in the thickness direction of the display panel to form a multi-layer light-shielding structure in the thickness direction, blocking the large-angle light emitted by the privacy light-emitting part, thereby achieving the privacy effect.

[0046] In some embodiments, the number of light-shielding layers in the display panel is not limited to the three layers in the above embodiments; the display panel may also have one, two, or three or more light-shielding layers. In some embodiments, the display panel includes multiple data lines and multiple scan lines (not shown in the figure). The multiple data lines extend in the column direction Y and are spaced apart along the row direction X. The multiple scan lines extend in the row direction X and are spaced apart along the column direction Y. The first direction D1 is parallel to the extension direction of the scan lines or data lines.

[0047] In some embodiments, please refer to Figures 1 to 3 The first direction D1 is parallel to the extension direction of the data line, that is, the first direction D1 is parallel to the column direction Y. In practical applications, the first direction D1 can also be parallel to the extension direction of the scan line, that is, the first direction D1 is parallel to the row direction X.

[0048] In some embodiments, please refer to Figure 2 and Figure 3 In the adjacent normal pixel P1 and privacy pixel P2, the second normal sub-pixel SP12 is located on the side of the second privacy sub-pixel SP22 away from the first privacy sub-pixel SP21. This allows the second normal sub-pixel SP12 to be away from the first privacy pixel SP21, preventing the light emitted by the second normal sub-pixel SP12 from being blocked by the light-shielding part above the first privacy pixel SP21.

[0049] In some embodiments, the center distance between the first normal sub-pixel SP11 and the adjacent first privacy sub-pixel SP21 is greater than the center distance between the second normal sub-pixel SP12 and the adjacent second privacy sub-pixel SP22.

[0050] Please see Figure 2 and Figure 3 The center distance between the first normal sub-pixel SP11 and the adjacent first privacy sub-pixel SP21 is the first distance s1, and the center distance between the second normal sub-pixel SP12 and the adjacent second privacy sub-pixel SP22 is the second distance s2. The first distance s1 is greater than the second distance s2. This can increase the spacing between the first normal sub-pixel SP11 and the first privacy sub-pixel SP21 in the first direction D1, so as to increase the area of ​​the first normal sub-pixel SP11 and the first privacy sub-pixel SP21, thereby improving the lifespan of the first normal sub-pixel SP11 and the first privacy sub-pixel SP21.

[0051] In some embodiments, in adjacent normal pixels P1 and privacy pixels P2, the light-emitting material of at least one normal sub-pixel SP1 is continuously disposed with the light-emitting material of the adjacent privacy sub-pixel SP2 with the same light-emitting color, and covers the area between the normal sub-pixel SP1 and the adjacent privacy sub-pixel SP2 with the same light-emitting color.

[0052] In some embodiments, please refer to Figures 2 to 4 The light-emitting layer 1 includes a plurality of first light-emitting material portions 11. Figure 2 The area indicated by the dashed box is the orthographic projection shape of the first light-emitting material part 11 on the reference plane. The orthographic projection of the first light-emitting material part 11 on the reference plane covers the area between the orthographic projections of the first normal sub-pixel SP11 and the adjacent first privacy sub-pixel SP21 on the reference plane. The reference plane is parallel to the light-emitting surface of the display panel.

[0053] In some embodiments, the first normal sub-pixel SP11 and the adjacent first privacy sub-pixel SP21 share the same opening in the metal mask to deposit the light-emitting material. Figure 2 The orthographic projection shape of the first light-emitting material part 11 on the reference plane is the shape of the same opening in the metal mask shared by the first normal sub-pixel SP11 and the adjacent first privacy sub-pixel SP21.

[0054] In some embodiments, please refer to Figure 4The first normal sub-pixel SP11 has a first normal light-emitting portion 111, which is the light-emitting material of the first normal sub-pixel SP11. The first privacy sub-pixel SP21 has a first privacy light-emitting portion 112, which is the light-emitting material of the first privacy sub-pixel SP21. The first normal light-emitting portion 111 and the adjacent first privacy light-emitting portion 112 belong to different parts of the same first light-emitting material portion 11. The portion of the first light-emitting material portion 11 that contacts the anode of the first normal sub-pixel SP1 can be considered as the first normal light-emitting portion 111, and the portion of the first light-emitting material portion 11 that contacts the anode of the first privacy sub-pixel SP21 can be considered as the first privacy light-emitting portion 112. In actual operation, only the first normal light-emitting portion 111 and the first privacy light-emitting portion 112 emit light in the first light-emitting material portion 11; the portion of the first light-emitting material portion 11 between the first normal light-emitting portion 111 and the first privacy light-emitting portion 112 does not emit light.

[0055] In some embodiments, in adjacent normal pixels P1 and privacy pixels P2, the luminescent material of at least one normal sub-pixel SP1 and the adjacent privacy sub-pixel SP2 with the same luminescent color covers the first region A1.

[0056] In some embodiments, please refer to Figures 2 to 4 The first region A1 includes a first sub-region A11. The luminescent material of the first normal sub-pixel SP11 and the first privacy sub-pixel SP21 covers the first sub-region A11, that is, the first luminescent material part 11 completely overlaps with the first sub-region A11, and the first normal sub-pixel SP11 and the first privacy sub-pixel SP21 are located within the first sub-region A11.

[0057] In some embodiments, please refer to Figures 2 to 4 The light-emitting layer 1 includes a plurality of second light-emitting material portions 12. Figure 2 The area indicated by the dashed box is the orthographic projection shape of the second light-emitting material part 12 on the reference plane. The orthographic projection of the second light-emitting material part 12 on the reference plane covers the area between the orthographic projections of the second normal sub-pixel SP12 and the adjacent second privacy sub-pixel SP22 on the reference plane. The reference plane is parallel to the light-emitting surface of the display panel.

[0058] In some embodiments, the second normal sub-pixel SP12 and the adjacent second privacy sub-pixel SP22 share the same opening in the metal mask to deposit the light-emitting material. Figure 2 The orthographic projection shape of the second light-emitting material part 12 on the reference plane is the shape of the same opening in the metal mask shared by the second normal sub-pixel SP12 and the adjacent second privacy sub-pixel SP22.

[0059] In some embodiments, the second normal sub-pixel SP12 has a second normal light-emitting portion, and the second privacy sub-pixel SP22 has a second privacy light-emitting portion (not shown in the figure). The second normal light-emitting portion and the adjacent second privacy light-emitting portion belong to different parts of the same second light-emitting material portion 12. The portion of the second light-emitting material portion 12 that contacts the anode of the second normal sub-pixel SP12 can be regarded as the second normal light-emitting portion 121, and the portion of the second light-emitting material portion 12 that contacts the anode of the second privacy sub-pixel SP22 can be regarded as the second privacy light-emitting portion 122. In actual operation, only the second normal light-emitting portion 121 and the second privacy light-emitting portion 122 emit light in the second light-emitting material portion 12; the first light-emitting material portion 11 between the second normal light-emitting portion 121 and the second privacy light-emitting portion 122 does not emit light.

[0060] In some embodiments, please refer to Figure 2 and Figure 3 The first region A1 includes a second sub-region A12. The luminescent material of the second normal sub-pixel SP12 and the second privacy sub-pixel SP22 covers the second sub-region A12, that is, the second luminescent material part 12 completely overlaps with the second sub-region A12, and the second normal sub-pixel SP12 and the second privacy sub-pixel SP22 are located within the second sub-region A12.

[0061] In some embodiments, the area of ​​the first normal sub-pixel SP11 is larger than the area of ​​the second normal sub-pixel SP12, and the area of ​​the first privacy sub-pixel SP21 is larger than the area of ​​the second privacy sub-pixel SP22. This increases the area of ​​the first normal sub-pixel SP11 and the first privacy sub-pixel SP21, thereby improving their lifespan.

[0062] In some embodiments, the area of ​​the first normal sub-pixel SP11 refers to the area of ​​the light-emitting region of the first sub-pixel SP11. The areas of other normal sub-pixels and privacy sub-pixels are also the same, and will not be elaborated here.

[0063] In some embodiments, the light-emitting part with the fastest lifespan decay among the three colors can be designated as the first normal sub-pixel SP11 and the first privacy sub-pixel SP21. For example, the blue light-emitting part typically decays the fastest, so the light-emitting color of the first normal sub-pixel SP11 and the first privacy sub-pixel SP21 can be set to blue, and the light-emitting color of the second normal sub-pixel SP12 and the second privacy sub-pixel SP22 can be either red or green.

[0064] In some embodiments, normal pixel P1 further includes a third normal sub-pixel SP13 that emits a third color light, and privacy pixel P2 further includes a third privacy sub-pixel SP23 that emits a third color light. The extension direction of the center line connecting the first normal sub-pixel SP11 and the adjacent first privacy sub-pixel SP21 intersects the extension direction of the center line connecting the third normal sub-pixel SP13 and the adjacent third privacy sub-pixel SP23, and is perpendicular to the thickness direction of the display panel.

[0065] Please see Figure 2 and Figure 3 In adjacent normal pixels P1 and privacy pixels P2, the center line connecting the first normal sub-pixel SP11 and the adjacent first privacy sub-pixel SP21 extends along the first direction D1, and the center line connecting the third normal sub-pixel SP13 and the adjacent third privacy sub-pixel SP23 extends along the third direction D3. The first direction D1 intersects the third direction D3 and is perpendicular to the thickness direction of the display panel.

[0066] By making the extension direction of the center line connecting the third normal sub-pixel SP13 and the third privacy sub-pixel SP23 non-parallel to the extension direction of the center line connecting the first normal sub-pixel SP11 and the first privacy sub-pixel SP21, the first privacy sub-pixel SP21 and the adjacent third privacy sub-pixel SP23 can be staggered while ensuring that the minimum spacing between the first privacy sub-pixel SP21 and the adjacent third privacy sub-pixel SP23 remains unchanged. This is beneficial to increase the area of ​​at least one of the first normal sub-pixel SP11, the first privacy sub-pixel SP21, the third normal sub-pixel SP13 and the third privacy sub-pixel SP23, thereby increasing the area of ​​the lifespan of the normal pixel and / or the privacy pixel, and thus increasing the lifespan of the light-emitting part and / or the privacy light-emitting part.

[0067] In some embodiments, please refer to Figure 2 and Figure 3 In the adjacent normal pixel P1 and privacy pixel P2, the third normal sub-pixel SP13 is located on the side of the third privacy sub-pixel SP23 that is away from the first privacy sub-pixel SP21. This keeps the third normal sub-pixel SP13 away from the first privacy sub-pixel SP21, preventing the light emitted by the third normal sub-pixel SP13 from being blocked by the light-shielding part above the first privacy sub-pixel SP21.

[0068] In some embodiments, the center distance between the first normal sub-pixel SP11 and the adjacent first privacy sub-pixel SP21 is greater than the center distance between the third normal sub-pixel SP13 and the adjacent third privacy sub-pixel SP23.

[0069] Please see Figure 2 and Figure 3The center distance between the first normal sub-pixel SP11 and the adjacent first privacy sub-pixel SP21 is the first distance s1, and the center distance between the third normal sub-pixel SP13 and the adjacent third privacy sub-pixel SP23 is the third distance s3. The first distance s1 is greater than the third distance s3. This can increase the spacing between the first normal sub-pixel SP11 and the first privacy sub-pixel SP21 in the first direction D1, so as to increase the area of ​​the first normal sub-pixel SP11 and the first privacy light-emitting part 112, thereby improving the lifespan of the first normal light-emitting part 111 and the first privacy sub-pixel SP21.

[0070] In some embodiments, the light-emitting material of the third normal sub-pixel SP13 and the light-emitting material of the third privacy sub-pixel SP23 are continuously disposed and cover the area between the third normal sub-pixel SP13 and the third privacy sub-pixel SP23.

[0071] In some embodiments, please refer to Figure 2 and Figure 3 The light-emitting layer 1 includes a third light-emitting material portion 13 adjacent to the first light-emitting material portion 11 and the second light-emitting material portion 12. Figure 2 The area indicated by the dashed box is the orthographic projection shape of the third light-emitting material part 13 on the reference plane. The orthographic projection of the third light-emitting material part 13 on the reference plane covers the area between the orthographic projections of the third normal sub-pixel SP13 and the adjacent third privacy sub-pixel SP23 on the reference plane. In some embodiments, the third normal sub-pixel SP13 and the adjacent third privacy sub-pixel SP23 share the same opening of the metal mask for evaporating light-emitting material. Figure 2 The orthographic projection shape of the third light-emitting material part 13 on the reference plane is the shape of the same opening of the metal mask plate shared by the third normal sub-pixel SP13 and the adjacent third privacy sub-pixel SP23.

[0072] In some embodiments, please refer to Figure 2 and Figure 3 The third normal sub-pixel SP13 has a third normal light-emitting portion 131, and the third privacy-protecting sub-pixel SP23 has a third privacy-protecting light-emitting portion 132. The third normal light-emitting portion 131 and the adjacent third privacy-protecting light-emitting portion 132 belong to different parts of the same third light-emitting material portion 13. The portion of the third light-emitting material portion 13 that contacts the anode of the third normal sub-pixel SP13 can be considered as the third normal light-emitting portion 131, and the portion of the third light-emitting material portion 13 that contacts the anode of the third privacy-protecting sub-pixel SP23 can be considered as the third privacy-protecting light-emitting portion 132. In actual operation, only the third normal light-emitting portion 131 and the third privacy-protecting light-emitting portion 132 emit light in the third light-emitting material portion 13; the portion of the third light-emitting material portion 13 between the third normal light-emitting portion 131 and the third privacy-protecting light-emitting portion 132 does not emit light.

[0073] In some embodiments, please refer to Figure 2 and Figure 3 The multiple first regions A1 also include a third sub-region A13, where the luminescent material of the third normal sub-pixel SP13 and the third privacy sub-pixel SP23 covers the third sub-region A13, that is, the third luminescent material part 13 completely overlaps with the third sub-region A13, and the third normal sub-pixel SP13 and the third privacy sub-pixel SP23 are located within the third sub-region A13.

[0074] In some embodiments, the area of ​​the first normal sub-pixel SP11 is larger than the area of ​​the third normal sub-pixel SP23, and the area of ​​the first privacy sub-pixel SP21 is larger than the area of ​​the third privacy sub-pixel SP23. This increases the area of ​​the first normal sub-pixel SP11 and the first privacy sub-pixel SP21, thereby improving their lifespan.

[0075] It should be noted that the light-emitting part with the fastest lifespan decay among the three colors can be designated as the first normal sub-pixel SP11 and the second privacy sub-pixel SP21. For example, since the blue light-emitting part typically decays the fastest, the light-emitting color of the first normal sub-pixel SP11 and the second privacy sub-pixel SP21 can be set to blue. The light-emitting color of the second normal sub-pixel SP12 and the second privacy sub-pixel SP22 can be either red or green, and the light-emitting color of the third normal sub-pixel SP13 and the third privacy sub-pixel SP23 can be either red or blue.

[0076] In some embodiments, the angle between the extension direction of the center line connecting the first normal sub-pixel SP11 and the adjacent first privacy sub-pixel SP21 and the extension direction of the center line connecting the second normal sub-pixel SP12 and the adjacent second privacy sub-pixel SP22 is greater than or equal to 30 degrees and less than or equal to 90 degrees.

[0077] In one embodiment, please refer to Figure 2 and Figure 3 There is a first angle a1 between the first direction D1 and the second direction D2. The first angle a1 is equal to 90 degrees, that is, the first direction D1 is perpendicular to the second direction D2. In this way, while keeping the minimum distance between the first privacy light-emitting part SP21 and the adjacent second privacy light-emitting part SP22 unchanged, the first privacy sub-pixel SP21 and the adjacent second privacy sub-pixel SP22 can be staggered, so as to increase the area of ​​the first privacy sub-pixel SP21 and the first normal sub-pixel SP11, thereby improving the lifespan of the first privacy sub-pixel SP21 and the first normal sub-pixel SP11.

[0078] In some embodiments, the angle between the extension direction of the center line connecting the first normal sub-pixel SP11 and the adjacent first privacy sub-pixel SP21 and the extension direction of the center line connecting the third normal sub-pixel SP13 and the adjacent third privacy sub-pixel SP23 is greater than or equal to 30 degrees and less than or equal to 90 degrees.

[0079] In one embodiment, please refer to Figure 2 and Figure 3 The first direction D1 and the third direction D3 have a second included angle a2, which is equal to 90 degrees. That is, the first direction D1 is perpendicular to the third direction D3, and the third direction D3 is parallel to the second direction D2. In this way, while keeping the minimum distance between the first privacy light-emitting part SP21 and the adjacent third privacy light-emitting part SP23 unchanged, the first privacy sub-pixel SP21 and the adjacent third privacy sub-pixel SP23 can be staggered, so as to increase the area of ​​the first privacy sub-pixel SP21 and the first normal sub-pixel SP11, thereby improving the lifespan of the first privacy sub-pixel SP21 and the first normal sub-pixel SP11.

[0080] In some embodiments, please refer to Figure 2 Multiple first normal sub-pixels SP11 and multiple first privacy sub-pixels SP21 are alternately arranged in the same column along the column direction Y of the display panel. Multiple second privacy sub-pixels SP22 and multiple third privacy sub-pixels SP23 are alternately arranged in a column adjacent to the column where the first privacy sub-pixels SP21 are located, along the column direction Y. Multiple second normal sub-pixels SP12 and multiple third normal sub-pixels SP13 are alternately arranged in a column adjacent to the column where the second privacy sub-pixels SP22 are located, along the column direction Y. The extension direction of the line connecting the center of the first normal sub-pixel and the adjacent first privacy sub-pixel is parallel to the column direction Y.

[0081] In some embodiments, please refer to Figure 2 and Figure 3 Multiple first normal sub-pixels SP11 and multiple first privacy sub-pixels SP21 are arranged alternately in the same column along the column direction Y of the display panel. Multiple second privacy sub-pixels SP22 and multiple third privacy sub-pixels SP23 are arranged alternately in the column direction Y in a column adjacent to the column where the first privacy sub-pixels SP21 are located. Multiple second normal sub-pixels SP12 and multiple third normal sub-pixels SP13 are arranged alternately in the column direction Y in a column adjacent to the column where the second privacy sub-pixels SP22 are located.

[0082] In some embodiments, in adjacent normal pixels P1 and privacy pixels P2, the area enclosed by the first privacy sub-pixel SP21, the second privacy sub-pixel SP22, and the third privacy sub-pixel SP23 does not overlap with the area enclosed by the first normal sub-pixel SP11, the second normal sub-pixel SP12, and the third normal sub-pixel SP13.

[0083] Please see Figure 2 and Figure 3 The center lines connecting the first normal sub-pixel SP11, the second normal sub-pixel SP12, and the third normal sub-pixel SP13 form a first virtual triangle VT1, and the center lines connecting the first privacy sub-pixel SP21, the second privacy sub-pixel SP22, and the third privacy sub-pixel SP23 form a second virtual triangle VT2. Both the first virtual triangle VT1 and the second virtual triangle VT2 are acute triangles. The area enclosed by the first normal sub-pixel SP11, the second normal sub-pixel SP12, and the third normal sub-pixel SP13 can be considered as the area where the first virtual triangle VT1 is located, and the area enclosed by the first privacy sub-pixel SP21, the second privacy sub-pixel SP22, and the third privacy sub-pixel SP23 is the area where the second virtual triangle VT2 is located.

[0084] It should be noted that the first virtual triangle VT1 and the second virtual triangle VT2 are virtual graphics and do not actually exist. By setting the centers of the first privacy pixel SP21, the second privacy pixel SP22, and the third privacy pixel SP23 at the three vertices of the second virtual triangle, and making the second virtual triangle an acute triangle, the first privacy pixel SP21 and the second privacy pixel SP22 can be offset in the row direction X. At the same time, the first privacy pixel SP21 and the third privacy pixel SP23 can also be offset in the row direction X. While ensuring that the minimum spacing between the first privacy pixel SP21 and the second privacy pixel SP22 remains unchanged, the first privacy pixel... While keeping the minimum spacing between sub-pixel SP21 and the third privacy sub-pixel SP23 unchanged, the first privacy sub-pixel SP21 can be moved closer to the second privacy sub-pixel SP22 and the third privacy sub-pixel SP23 in the row direction X, thereby saving a certain amount of space in the row direction X. The saved space can be contributed to other privacy light-emitting parts and / or normal light parts, thereby increasing the area of ​​other privacy light-emitting parts and / or normal light parts. By increasing the area of ​​privacy light-emitting parts and / or normal light parts, the lifespan of privacy light-emitting parts and / or normal light parts can be improved.

[0085] By ensuring that the area enclosed by the first privacy sub-pixel SP21, the second privacy sub-pixel SP22, and the third privacy sub-pixel SP23 does not overlap with the area enclosed by the first normal sub-pixel SP11, the second normal sub-pixel SP12, and the third normal sub-pixel SP13, the first virtual triangle VT1 and the second virtual triangle VT2 can be prevented from being separated by other privacy sub-pixels or normal sub-pixels. This makes the three privacy sub-pixels of the second virtual triangle VT2 adjacent, which is more conducive to the synthesis of white light. Similarly, making the three normal light-emitting parts in the first virtual triangle VT1 adjacent is also more conducive to the synthesis of white light, thereby improving the color fringing problem in the displayed image.

[0086] In some embodiments, please refer to Figure 2 The centers of multiple normal pixels P1 are arranged in the same column along the column direction Y of the display panel, and the centers of multiple privacy pixels P2 are arranged in a column adjacent to the column where the center of the normal pixels P1 is located; and / or, the centers of multiple normal pixels P1 are arranged in the same row along the row direction X of the display panel, and the centers of multiple privacy pixels P2 are arranged in a row adjacent to the row where the center of the normal pixels P1 is located.

[0087] It should be noted that the center of the normal pixel P1 is the geometric center of the first virtual triangle VT1, and the center of the privacy pixel P2 is the geometric center of the second virtual triangle VT2. By arranging the centers of the normal pixel P1 and the privacy pixel P2 in a staggered manner, not only can the color fringing problem in the displayed image be improved, but the pixel density of the display panel can also be increased.

[0088] Please see Figure 5 and Figure 6 , Figure 5 This is an enlarged view of point a in the second type of display panel provided for an embodiment of this application. Figure 6 A schematic diagram of a privacy pixel in a second type of display panel provided for an embodiment of this application, the structure of which is similar to... Figures 1 to 4 The structure of the first type of display panel shown is roughly the same, except that: the second direction D2 is different from the row direction X; and / or, the third direction D3 is different from the row direction X.

[0089] In some embodiments, please refer to Figure 5 and Figure 6 The first included angle α1 between the first direction D1 and the second direction D2 is greater than or equal to 30 degrees and less than 90 degrees. For example, the first included angle α1 can be 30 degrees, 40 degrees, 45 degrees, 50 degrees, 60 degrees, 70 degrees, 80 degrees, 85 degrees, or 87 degrees, etc. By tilting the second normal sub-pixel SP12 and the adjacent second privacy sub-pixel SP22, since the second normal sub-pixel SP12 and the adjacent second privacy sub-pixel SP22 share the same opening of the metal mask for evaporating organic light-emitting material, the center distance between the second normal sub-pixel SP12 and the adjacent second privacy sub-pixel SP22 can be increased. While keeping the minimum spacing between the second normal sub-pixel SP12 and the adjacent second privacy sub-pixel SP22 unchanged, the area of ​​the second normal sub-pixel SP12 and the adjacent second privacy sub-pixel SP22 can be increased, thereby improving the lifespan of the second normal sub-pixel SP12 and the adjacent second privacy sub-pixel SP22.

[0090] In some embodiments, the first included angle α1 between the first direction D1 and the second direction D2 is greater than or equal to 30 degrees and less than or equal to 80 degrees. This allows for an increase in the area of ​​the second normal sub-pixel SP12 and the adjacent second privacy sub-pixel SP22 while maintaining the minimum spacing between them. This, in turn, can improve the lifespan of the second normal sub-pixel SP12 and the adjacent second privacy sub-pixel SP22.

[0091] In some embodiments, among adjacent normal pixels P1 and privacy pixels P2, at least one normal sub-pixel SP1 and an adjacent privacy sub-pixel SP2 with the same emission color are respectively located near two diagonal vertices of the first region A1.

[0092] In some embodiments, please refer to Figure 5 and Figure 6 The second normal sub-pixel SP12 and the adjacent second privacy sub-pixel SP22 are located within the corresponding second sub-region A12, which is rectangular. The second normal sub-pixel SP12 and the adjacent second privacy sub-pixel SP22 are positioned close to the two opposite corner vertices of the second sub-region A12. This maximizes the center distance between the second normal sub-pixel SP12 and the adjacent second privacy sub-pixel SP22, thereby increasing their area and ultimately improving their lifespan.

[0093] In some embodiments, among adjacent normal pixels P1 and privacy pixels P2, the centers of at least one normal sub-pixel SP1 and an adjacent privacy sub-pixel SP2 with the same emission color are located on the same diagonal of the first region A1.

[0094] In some embodiments, please refer to Figure 7 , Figure 7 A schematic diagram of a privacy pixel in a third type of display panel provided for an embodiment of this application, the structure of which is similar to... Figure 6 The display panels shown have roughly the same structure, the difference being that the second normal sub-pixel SP12 and the adjacent second privacy sub-pixel SP22 are located within the corresponding second sub-region A12. The second sub-region A12 is rectangular, and the centers of the second normal sub-pixel SP12 and the adjacent second privacy sub-pixel SP22 are located on one of the diagonals of the second sub-region A12. This maximizes the center distance between the second normal sub-pixel SP12 and the adjacent second privacy sub-pixel SP22, thereby further increasing the area of ​​the second normal sub-pixel SP12 and the adjacent second privacy sub-pixel SP22, and thus further improving their lifespan.

[0095] In some embodiments, please refer to Figure 5 and Figure 6 The second included angle α2 between the first direction D1 and the third direction D3 is greater than or equal to 30 degrees and less than 90 degrees. For example, the second included angle α2 can be 30 degrees, 40 degrees, 45 degrees, 50 degrees, 60 degrees, 70 degrees, 80 degrees, 85 degrees, or 87 degrees, etc. By tilting the third normal sub-pixel SP13 and the adjacent third privacy sub-pixel SP23, since the third normal sub-pixel SP13 and the adjacent third privacy sub-pixel SP23 share the same opening of the metal mask for evaporating organic light-emitting material, the center distance between the third normal sub-pixel SP13 and the adjacent third privacy sub-pixel SP23 can be increased. While ensuring that the minimum spacing between the third normal sub-pixel SP13 and the adjacent third privacy sub-pixel SP23 remains unchanged, the area of ​​the third normal sub-pixel SP13 and the adjacent third privacy sub-pixel SP23 can be increased, thereby improving the lifespan of the third normal sub-pixel SP13 and the adjacent third privacy sub-pixel SP23.

[0096] In some embodiments, the second included angle α2 between the first direction D1 and the third direction D3 is greater than or equal to 30 degrees and less than or equal to 80 degrees. Thus, while maintaining the minimum spacing between the third normal sub-pixel SP13 and the adjacent third privacy sub-pixel SP23, the area of ​​the third normal sub-pixel SP13 and the adjacent third privacy sub-pixel SP23 can be increased, thereby improving their lifespan.

[0097] In some embodiments, please refer to Figure 5 and Figure 6 The third normal sub-pixel SP13 and the adjacent third privacy sub-pixel SP23 are located within the corresponding third sub-region A13, which is rectangular. The third normal sub-pixel SP13 and the adjacent third privacy sub-pixel SP23 are positioned close to the two opposite corner vertices of the third sub-region A13. This maximizes the center distance between the third normal sub-pixel SP13 and the adjacent third privacy sub-pixel SP23, thereby increasing their area and ultimately improving their lifespan.

[0098] In some embodiments, please refer to Figure 7The third normal sub-pixel SP13 and the adjacent third privacy sub-pixel SP23 are located within the corresponding third sub-region A13. The third sub-region A13 is rectangular, and the center of the third normal sub-pixel SP13 and the adjacent third privacy sub-pixel SP23 is located on one of the diagonals of the third sub-region A13. This maximizes the center distance between the third normal sub-pixel SP13 and the adjacent third privacy sub-pixel SP23, thereby further increasing the area of ​​the third normal sub-pixel SP13 and the adjacent third privacy sub-pixel SP23 and thus further improving their lifespan.

[0099] In some embodiments, the angle between the first direction D1 and the second direction D2 is equal to the angle between the first direction D1 and the third direction D3.

[0100] Please see Figure 5 and Figure 6 The first included angle a1 and the second included angle a2 are equal. For example, the first included angle a1 and the second included angle a2 are both 30 degrees; or, the first included angle a1 and the second included angle a2 are both 45 degrees; or, the first included angle a1 and the second included angle a2 are both 80 degrees, etc.

[0101] In some embodiments, the angle between the first direction D1 and the second direction D2 may not be equal to the angle between the first direction D1 and the third direction D3. The first angle a1 can be greater than the second angle a2, or the first angle a1 can be less than the second angle a2. The values ​​of the first angle a1 and the second angle a2 only need to be between 30 degrees and 80 degrees to increase the area of ​​the second normal sub-pixel SP12, the second privacy sub-pixel SP22, the third normal sub-pixel SP13, and the third privacy sub-pixel SP23, thereby improving their lifespan.

[0102] Based on the display panel provided in the above embodiments of this application, embodiments of this application also provide a display device. Please refer to [link to relevant documentation]. Figure 8 , Figure 8 This is a schematic diagram of the structure of a display device provided in an embodiment of this application.

The display panel 100 can be any of the display panels provided in the above embodiments, and can achieve the same technical effects as the display panels provided in the above embodiments, which will not be described in detail here.

[0103] In some embodiments, the display device 1000 may be any product or component with display function, such as a mobile phone, tablet computer, television, monitor, laptop computer, digital photo frame, or navigator.

[0104] The beneficial effects of the embodiments of this application are as follows: The embodiments of this application provide a display panel and a display device. The display panel includes normal pixels and privacy pixels. The normal pixels include a first normal sub-pixel that emits a first color light and a second normal sub-pixel that emits a second color light. The privacy pixels include a first privacy sub-pixel that emits a first color light and a second privacy sub-pixel that emits a second color light. By making the extension direction of the center line connecting the center of the first normal sub-pixel and the adjacent first privacy sub-pixel intersect with the extension direction of the center line connecting the center of the second normal sub-pixel and the adjacent second privacy sub-pixel, the first privacy sub-pixel and the adjacent second privacy sub-pixel can be staggered while ensuring that the minimum spacing between the first privacy sub-pixel and the adjacent second privacy sub-pixel remains unchanged. This is beneficial to increasing the area of ​​the normal pixels and the privacy pixels, thereby improving the lifespan of the normal pixels and / or the privacy pixels.
