Description

Technical Field

[0001] This application belongs to the field of display device technology, specifically relating to a privacy display panel and a display device. Background Technology

[0002] With the increasing prevalence of mobile phones and laptops, these devices have permeated every aspect of life and work, making the protection of personal and confidential information an issue that cannot be ignored. This is especially true for mobile phones and laptops, which are associated with a large amount of personal information; leaks can have serious consequences. Currently, the most common privacy protection method is external Venetian blind film, which, while simple and convenient, severely impacts viewing experience, reducing brightness by half and producing moiré patterns. Most critically, it lacks a one-click switching function; during normal use, the wide-viewing-angle mode is unavailable, sacrificing screen sharing functionality. Therefore, a one-click switching function is the ideal privacy protection technology.

[0003] However, when implementing one-click privacy technology, OLED display panels often require additional privacy pixels and a privacy light-blocking layer positioned opposite them. The privacy light-blocking layer affects the light emission of adjacent normal display pixels. Increasing the distance between the normal display pixels and the privacy pixels significantly reduces the aperture ratio of the normal display pixels. Conversely, bringing the distance closer results in some normal display pixels being blocked while others remain unblocked, leading to viewer distortion and affecting the visual experience. Summary of the Invention

[0004] The purpose of this application is to provide a privacy display panel and display device that can almost not cause color distortion when viewing the display screen at a large angle under privacy viewing conditions, even if the brightness is blocked by a privacy light-blocking layer.

[0005] This application discloses a privacy display panel in its first aspect, comprising: a substrate on which a plurality of pixel units are arranged in an array; each pixel unit comprising: a light-emitting group, the light-emitting group comprising a privacy sub-pixel and a first display sub-pixel, a second display sub-pixel, and a third display sub-pixel with different emission colors, wherein the emission color of the privacy sub-pixel is different from at least one of the emission colors of the first display sub-pixel, the second display sub-pixel, and the third display sub-pixel, and the first display sub-pixel, the privacy sub-pixel, and the second display sub-pixel are arranged sequentially at intervals in a first direction; and a light-shielding layer disposed on the side of the light-emitting group away from the substrate. The light-shielding layer includes a privacy light-shielding part and an auxiliary light-shielding part. The orthogonal projection of the privacy light-shielding part on the substrate covers the orthogonal projection of the privacy sub-pixel on the substrate and is spaced from the orthogonal projections of the first to third display sub-pixels on the substrate. The first display sub-pixel and the second display sub-pixel are each provided with the auxiliary light-shielding part on the side away from the privacy sub-pixel in the first direction and are spaced from the orthogonal projection of the auxiliary light-shielding part on the substrate. The third display sub-pixel is provided with the auxiliary light-shielding part on both opposite sides in the first direction and is spaced from the orthogonal projection of the auxiliary light-shielding part on the substrate.

[0006] In one exemplary embodiment of this application, along a second direction, the first display sub-pixel, the privacy sub-pixel, and the second display sub-pixel are located on the same side of the third display sub-pixel in the second direction; wherein, the second direction intersects with the first direction.

[0007] In an exemplary embodiment of this application, the distance between the first display sub-pixel and the adjacent auxiliary light-shielding portion in the first direction is a first distance; the distance between the second display sub-pixel and the adjacent auxiliary light-shielding portion in the first direction is a second distance; the distance between the third display sub-pixel and the adjacent auxiliary light-shielding portion in the first direction is a third distance; and the distance between the privacy light-shielding portion and the adjacent first display sub-pixel and second display sub-pixel in the first direction is a fourth distance; wherein, the first distance, the second distance, the third distance, and the fourth distance are all equal.

[0008] In one exemplary embodiment of this application, the first display sub-pixel and the second display sub-pixel are offset from the edge of the adjacent third display sub-pixel on the side of the first direction away from the privacy sub-pixel; wherein, the auxiliary light-shielding part includes a first light-shielding block and a second light-shielding block, and the first light-shielding block and the second light-shielding block are offset from each other along the first direction; The third display sub-pixel has the first light-shielding block on both sides of the first direction, and there is a distance between the auxiliary light-shielding part and the orthogonal projection on the substrate; the first display sub-pixel and the second display sub-pixel have the second light-shielding block on the side of the first direction away from the privacy sub-pixel, and there is a distance between the second light-shielding block and the orthogonal projection on the substrate.

[0009] In an exemplary embodiment of this application, in two adjacent pixel units: along the first direction, the side of the first light-shielding block of one pixel unit is connected to the side of the first light-shielding block of the other pixel unit, and the side of the second light-shielding block of one pixel unit is connected to the side of the second light-shielding block of the other pixel unit.

[0010] In one exemplary embodiment of this application, along the second direction, the auxiliary light-shielding portion includes a first light-shielding block and a second light-shielding block spaced apart; the third display sub-pixel has the first light-shielding block on each of its opposite sides in the first direction, and has a distance between it and the orthographic projection of the auxiliary light-shielding portion on the substrate; the first display sub-pixel and the second display sub-pixel both have the second light-shielding block on the side of the first direction away from the privacy sub-pixel, and have a distance between it and the orthographic projection of the second light-shielding block on the substrate.

[0011] In one exemplary embodiment of this application, along the second direction: the opposite sides of the orthographic projection of the privacy shield on the substrate are respectively provided to protrude from the opposite sides of the orthographic projection of the first display sub-pixel and the second display sub-pixel on the substrate; wherein, the opposite sides of the orthographic projection of the first light shield on the substrate are respectively provided to protrude from the opposite sides of the third display sub-pixel; the opposite sides of the orthographic projection of the second light shield on the substrate are respectively provided to protrude from the opposite sides of the orthographic projection of the first display sub-pixel and the second display sub-pixel on the substrate.

[0012] In an exemplary embodiment of this application, along the second direction: the distances between the opposite sides of the orthographic projection of the first light-shielding block on the substrate and the opposite sides of the third display sub-pixel are both first distances; the distances between the opposite sides of the orthographic projection of the second light-shielding block on the substrate and the opposite sides of the orthographic projection of the second display sub-pixel on the substrate are both second distances; the first distance and the second distance are equal, and their range is less than or equal to 25 μm.

[0013] In one exemplary embodiment of this application, the first spacing is less than or equal to 25 μm.

[0014] A second aspect of this application discloses a display device, including a housing and the aforementioned privacy display panel, wherein the privacy display panel is connected to the housing.

[0015] The proposed solution has the following beneficial effects: In this embodiment, since the first display sub-pixel of the privacy display panel has an auxiliary light-shielding portion on the side away from the privacy sub-pixel in the first direction, and the third display sub-pixel has the same auxiliary light-shielding portion on both opposite sides in the first direction, when a user views the light emitted by the first display sub-pixel, the privacy sub-pixel, and the second display sub-pixel sequentially at a large angle along the first direction: If the second display sub-pixel is affected by the privacy shield, causing its light intensity to be weaker than that of the first and third display sub-pixels, some of the light emitted by the first and third display sub-pixels will also be blocked by the auxiliary shield, ultimately ensuring that the light intensity of the second display sub-pixel is not significantly weaker than that of the first and third display sub-pixels. This solves the color shift problem caused by the privacy shield, thereby optimizing the aperture ratio of the privacy display panel and enhancing its lifespan.

[0016] Furthermore, when a user views the light emitted by the second display sub-pixel, the privacy sub-pixel, and the first display sub-pixel in sequence at a large angle along the first direction, the principle for solving the color shift problem caused by the privacy shield is the same as when a user views the light emitted by the first display sub-pixel, the privacy sub-pixel, and the second display sub-pixel in sequence at a large angle along the first direction.

[0017] Other features and advantages of this application will become apparent from the following detailed description, or may be learned in part from practice of this application.

[0018] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application. Attached Figure Description

[0033] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided to make this application more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art.

[0034] Furthermore, the described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. Numerous specific details are provided in the following description to give a thorough understanding of embodiments of this application. However, those skilled in the art will recognize that the technical solutions of this application can be practiced without one or more of the specific details, or other methods, components, apparatuses, steps, etc., can be employed. In other instances, well-known methods, apparatuses, implementations, or operations are not shown or described in detail to avoid obscuring various aspects of this application.

[0035] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present application, and should not be construed as limiting the present application.

[0036] Example 1 like Figures 1 to 4 As shown, this embodiment discloses a privacy display panel. The privacy display panel is, for example, an OLED (organic light-emitting diode) display panel.

[0037] The display panel may include a substrate 1 and a pixel defining layer 2. The substrate 1 has a display area and a non-display area. The non-display area may be disposed around the display area. The pixel defining layer 2 may be disposed on the display area of ​​the substrate 1.

[0038] It should be understood that the display panel may also include a driving circuit layer 3, which may be formed on the substrate 1 before the pixel defining layer 2 and the pixel unit 5. This driving circuit layer 3 may include circuit structures such as thin film transistors and wiring to drive the light-emitting device 4 mentioned later to emit light, which will not be elaborated on here.

[0039] For example, substrate 1 may be a rigid substrate made of glass, but is not limited to this, and may also be a flexible substrate made of materials such as polyimide (hereinafter referred to as polyimide). In other words, the display device of this application is not limited to a rigid, inflexible panel, but may also be a flexible, bendable panel.

[0040] In addition, the substrate 1 includes a first direction a and a second direction b, wherein the first direction a intersects the second direction b.

[0041] It should be understood that the first direction a is the width direction of the substrate 1 and the second direction b is the length direction of the substrate 1; or, the first direction a is the length direction of the substrate 1 and the second direction b is the width direction of the substrate 1.

[0042] like Figure 4 As shown, the pixel defining layer 2 may have multiple pixel openings arranged at intervals and pixel defining portions located between adjacent pixel openings. In other words, the pixel defining layer 2 as a whole can be regarded as a grid-like hollow structure layer. The hollow area is the pixel opening used to form pixels in this embodiment, and the non-hollow area is the pixel defining portion in this embodiment.

[0043] For example, the surface of this pixel defining portion away from the substrate 1 is planar, and this pixel defining layer 2 can be made of materials such as PI.

[0044] It should be understood that each pixel opening in the pixel defining layer 2 is provided with a corresponding number of light-emitting devices 4. That is to say, the number of light-emitting devices 4 and the number of pixel openings can be the same.

[0045] Furthermore, the light-emitting device 4 may include a display light-emitting diode, which includes a display anode 41, a display light-emitting portion 42, and a display cathode 43 stacked sequentially.

[0046] It should be understood that the display anodes 41 of each display light-emitting diode are spaced apart from each other so that each display light-emitting diode can be driven independently. The display cathodes 43 of each display light-emitting diode can be connected to each other to form a whole surface electrode, thereby reducing processing costs.

[0047] like Figure 4As shown, the light-emitting portion 42 can be located within the pixel opening. That is, when manufacturing the display device, the pixel defining layer 2 can be fabricated first, and then the light-emitting portion 42 can be fabricated after the pixel defining layer 2 is fabricated, so that the light-emitting portion 42 is formed within the pixel opening. For example, this light-emitting portion 42 can be formed within the pixel opening by means of vapor deposition or the like.

[0048] It should be understood that the display light-emitting part 42 may include a hole injection layer, a hole transport layer, an organic light-emitting material layer, an electron transport layer and an electron injection layer stacked in sequence. The hole injection layer is in contact with the display anode 41 and the electron injection layer is in contact with the display cathode 43. However, it is not limited to this. The display light-emitting part 42 may also include only the hole transport layer, the light-emitting material layer and the electron transport layer, or other structures, depending on the actual needs.

[0049] like Figure 4 As shown, the display cathode 43 can be formed after the display light-emitting portion 42 is formed and is in contact with the display light-emitting portion 42. This display cathode 43 may include a low work function material layer comprising Li, Ca, LiF / Ca, LiF / Al, Al, Mg, Ag, Pt, Pd, Ni, Au, Nd, Ir, Cr, BaF2, Ba, their compounds or mixtures thereof. For example, the display cathode 43 may include a low work function material layer made of a mixture of Ag and Mg.

[0050] In this embodiment, the light-emitting device 4 may include various types. Different types of light-emitting devices 4 have different light-emitting colors in their display light-emitting parts 42. For example, there are red type light-emitting devices 4, green type light-emitting devices 4, blue type light-emitting devices 4, etc. Red type light-emitting device 4 refers to the light-emitting color of the display light-emitting part 42 being red, green type light-emitting device 4 refers to the light-emitting color of the display light-emitting part 42 being green, and blue type light-emitting device 4 refers to the light-emitting color of the display light-emitting part 42 being blue.

[0051] In this design, the light-emitting device 4 can be understood as a sub-pixel in the display device. Adjacent red-type light-emitting devices 4, green-type light-emitting devices 4, blue-type light-emitting devices 4, and light-emitting devices 4 whose emission color type is at least different from that of red-type, green-type, or blue-type light-emitting devices 4 can form a light-emitting group. A light-emitting group and the light-shielding layer 6 form a pixel unit 5. The light-emitting group includes a privacy sub-pixel 54, a first display sub-pixel 51, a second display sub-pixel 52, and a third display sub-pixel 53, each with a different emission color. The emission color of the privacy sub-pixel 54 is at least different from the emission color of any one of the first display sub-pixel 51, the second display sub-pixel 52, and the third display sub-pixel 53.

[0052] In some embodiments, such as Figure 1As shown, the first display sub-pixel 51 is formed by a green type light-emitting device 4, the second display sub-pixel 52 is formed by a red type light-emitting device 4, the third display sub-pixel is formed by a blue type light-emitting device 4, and the privacy sub-pixel 54 is formed by a light-emitting device 4 other than red, green, or blue type light-emitting devices 4.

[0053] In this embodiment, the privacy sub-pixel 54 is formed by a yellow-type light-emitting device 4, the first display sub-pixel 51 is formed by a green-type light-emitting device 4, the second display sub-pixel 52 is formed by a red-type light-emitting device 4, and the third display sub-pixel is formed by a blue-type light-emitting device 4.

[0054] Of course, in other embodiments, the first display sub-pixel 51, the second display sub-pixel 52, the third display sub-image, and the privacy sub-pixel 54 can also be formed by light-emitting devices 4 of other color types. As long as the first display sub-pixel 51, the second display sub-pixel 52, and the third display sub-image emit different light-emitting color types, and the privacy sub-pixel 54 emits a different light-emitting color type from any of the other three display sub-pixels, it is acceptable.

[0055] Furthermore, such as Figure 1 As shown, in this embodiment, the first display sub-pixel 51, the privacy sub-pixel 54, and the second display sub-pixel 52 are arranged sequentially at intervals along the first direction a. That is, the privacy sub-pixel 54 is located between the first display sub-pixel 51 and the second display sub-pixel 52.

[0056] It should be understood that when the privacy sub-pixel 54 is located between the first display sub-pixel 51 and the second display sub-pixel 52, the light emitted by the privacy sub-pixel 54 can be easily mixed with the light of the first display sub-pixel 51 and the second display sub-pixel 52 at the same time. Therefore, compared with the privacy sub-pixel 54 being located on one side of the first display sub-pixel 51 and the second display sub-pixel 52 as a whole, it is easier to mix the light, and ultimately the privacy display panel has a better privacy effect.

[0057] like Figure 1 As shown, after the privacy sub-pixel 54 is located between the first display sub-pixel 51 and the second display sub-pixel 52, along the first direction a, the width of the privacy sub-pixel 54 is smaller than the pixels of the first display sub-pixel 51 and the second display sub-pixel 52, so as to avoid the privacy sub-pixel 54 being too wide and thus occupying the area of ​​the opening area of ​​the pixel unit 5, resulting in a decrease in the aperture ratio.

[0058] Furthermore, in other embodiments, to accommodate the area of ​​the pixel opening in the pixel unit 5 occupied by the privacy sub-pixel 54, the privacy sub-pixel 54 can be directly disposed on the side of the pixel defining portion away from the substrate 1, thus eliminating the need to reserve too much space between the first display sub-pixel 51 and the second display sub-pixel 52 to form a pixel opening for accommodating the light-emitting device 4 of the privacy sub-pixel 54. In other words, the privacy sub-pixel 54 can be directly disposed in the non-opening area of ​​the original non-privacy display panel.

[0059] The light-shielding layer 6 is disposed on the side of the light-emitting group away from the substrate 1. The light-shielding layer 6 includes a privacy light-shielding part 61 and an auxiliary light-shielding part 62.

[0060] It should be understood that the light-shielding layer 6 can be formed of metal or non-metal. When the light-shielding layer 6 is metal, it needs to be used in conjunction with a circular polarizer and / or an anti-reflection layer. The thickness of the light-shielding layer 6 ranges from 0.1 to 0.6 μm; optionally, its thickness is 0.1 μm, 0.2 μm, 0.3 μm, 0.4 μm, 0.5 μm, or 0.6 μm. When the light-shielding layer 6 is non-metallic, its thickness ranges from 0.5 to 3 μm; optionally, its thickness is 0.5 μm, 0.55 μm, 0.79 μm, 0.8 μm, 1.2 μm, or 1.5 μm.

[0061] It is worth noting that the light-shielding layer 6 is not the same as the black matrix layer between two adjacent color resist layers. The black matrix layer between color resist layers can only be formed by stacking photoresist, and the black matrix layer between adjacent color resist layers cannot be broken between each pixel unit 5. Furthermore, the black matrix layer between adjacent color resist layers is used to prevent light mixing between adjacent pixel units 5. However, the light-shielding layer 6 of this application can be broken between each pixel unit 5, and is not limited to being formed by stacking photoresist. Its function is to reduce the luminous intensity of each sub-pixel, not to prevent light mixing between adjacent pixel units 5. Most importantly, the light-shielding layer 6 of this application can be broken between each pixel unit 5, or it can be broken within the same pixel unit 5.

[0062] In some embodiments, the privacy light-blocking part 61 and the auxiliary light-blocking part 62 are disposed on the same layer, which facilitates the use of the same photomask process to manufacture them, thereby saving costs.

[0063] It should be understood that the privacy display panel also includes an encapsulation layer 7, which is disposed on the substrate 1 and covers the light-emitting group. The privacy light-shielding part 61 and the auxiliary light-shielding part 62 can be disposed in the same layer between the encapsulation layer 7 and the light-emitting group, or they can be disposed inside the encapsulation layer 7, or they can be disposed on the side of the encapsulation layer 7 away from the substrate 1.

[0064] For example, the encapsulation layer 7 includes a first inorganic layer 71, a second inorganic layer 72, and an organic layer 73, with the organic layer 73 located between the first inorganic layer 71 and the second inorganic layer 72. Both the first inorganic layer 71 and the second inorganic layer 72 are used for water and oxygen isolation, with the first inorganic layer 71 positioned closer to the substrate 1 than the second inorganic layer 72. The privacy shielding portion 61 and the auxiliary shielding portion 62 are both located between the first inorganic layer 71 and the organic layer 73. The planarization effect of the organic layer 73 makes the side of the organic layer 73 furthest from the first inorganic layer 71 a flat surface, facilitating subsequent fabrication processes.

[0065] The orthogonal projection of the privacy shield 61 on the substrate 1 covers the orthogonal projection of the privacy sub-pixel 54 on the substrate 1, and is spaced from the orthogonal projections of the first to third display sub-pixels 53 on the substrate 1. The first display sub-pixel 51 and the second display sub-pixel 52 are each provided with an auxiliary shield 62 on the side away from the privacy sub-pixel 54 in the first direction a, and are spaced from the orthogonal projections of the auxiliary shield 62 on the substrate 1. The third display sub-pixel 53 is provided with auxiliary shield 62 on both opposite sides in the first direction a, and is spaced from the orthogonal projections of the auxiliary shield 62 on the substrate 1.

[0066] Furthermore, the area of ​​the privacy shield 61 projected onto the substrate 1 is larger than the area of ​​the privacy sub-pixel 54 projected onto the substrate 1.

[0067] It should be understood that, since the first display sub-pixel 51 of the privacy display panel has an auxiliary light-shielding part 62 on the side away from the privacy sub-pixel 54 in the first direction a, and the third display sub-pixel 53 has auxiliary light-shielding parts 62 on both opposite sides in the first direction a, when a user views the light emitted by the first display sub-pixel 51, the privacy sub-pixel 54, and the second display sub-pixel 52 sequentially at a large angle along the first direction a: If the second display sub-pixel 52 is affected by the privacy light shield 61, causing its light intensity to be weaker than that of the first display sub-pixel 51 and the third display sub-pixel 53; some of the light emitted by the first display sub-pixel 51 and the third display sub-pixel 53 will also be blocked by the auxiliary light shield 62, so that the light intensity of the second display sub-pixel 52 will not be significantly weaker than that of the first display sub-pixel 51 and the third display sub-pixel 53, thereby solving the color shift problem caused by the privacy light shield 61, so as to optimize the aperture ratio of the privacy display panel and enhance its lifespan.

[0068] Furthermore, when a user views the light emitted by the second display sub-pixel 52, the privacy sub-pixel 54, and the first display sub-pixel 51 sequentially at a large angle along the first direction a, the principle for solving the color shift problem caused by the privacy light-blocking part 61 is the same as when a user views the light emitted by the first display sub-pixel 51, the privacy sub-pixel 54, and the second display sub-pixel 52 sequentially at a large angle along the first direction a.

[0069] In this embodiment, the first display sub-pixel 51, the privacy sub-pixel 54, and the second display sub-pixel 52 are located on the same side of the third display sub-pixel 53 along the second direction b. Since the first display sub-pixel 51, the privacy sub-pixel 54, and the second display sub-pixel 52 are arranged sequentially at intervals along the first direction a, they are all positioned around the privacy sub-pixel 54. This allows the light emitted by the privacy sub-pixel 54 to mix with the light emitted by any one or more of the first display sub-pixels 51, the second display sub-pixel 52, and the third display sub-pixel 53, further enhancing the privacy protection effect.

[0070] In some embodiments, the distance between the first display sub-pixel 51 and its adjacent auxiliary light-shielding portion 62 in the first direction a is a first distance d1; the distance between the second display sub-pixel 52 and its adjacent auxiliary light-shielding portion 62 in the first direction a is a second distance d2; the distance between the third display sub-pixel 53 and its adjacent auxiliary light-shielding portion 62 in the first direction a is a third distance d3; and the distance between the privacy light-shielding portion 61 and its adjacent first display sub-pixel 51 and second display sub-pixel 52 in the first direction a is a fourth distance d4; wherein the first distance d1, the second distance d2, the third distance d3, and the fourth distance d4 are all equal.

[0071] In other words, along the first direction a: the vertical distance between the first display sub-pixel 51, the second display sub-pixel 52, the third display sub-pixel 53 and their nearest auxiliary light-shielding part 62 is equal everywhere, and is equal to the vertical distance between the first display sub-pixel 51, the second display sub-pixel 52 and their nearest privacy light-shielding part 61.

[0072] It should be understood that when the vertical distances between the first display sub-pixel 51, the second display sub-pixel 52, the third display sub-pixel 53 and their nearest auxiliary light-shielding part 62 are equal everywhere along the first direction a, and are equal to the vertical distances between the first display sub-pixel 51, the second display sub-pixel 52 and their nearest privacy light-shielding part 61, it can be achieved that even with the privacy light-shielding part 61 blocking the view at the same angle, color shift can be almost completely guaranteed, thereby achieving the design of optimizing the aperture ratio and increasing the lifespan of the privacy display panel.

[0073] For example, the values ​​of the first spacing d1, the second spacing d2, the third spacing d3, and the fourth spacing d4 are less than or equal to 25 μm.

[0074] Optionally, the values ​​of the first spacing d1, the second spacing d2, the third spacing d3, and the fourth spacing d4 are 5μm, 5.6μm, 6.5μm, 7.1μm, 8.2μm, 9.7μm, 10μm, 11μm, or 12.5μm, etc.

[0075] In this embodiment, one side of the third display sub-pixel 53 is on the same horizontal line as the side of the first display sub-pixel 51 away from the privacy sub-pixel 54; the other side of the third display sub-pixel 53 is on the same horizontal line as the side of the second display sub-pixel 52 away from the privacy sub-pixel 54. At this time, the width of the auxiliary light-shielding portion 62 is the same everywhere along the first direction a.

[0076] It should be understood that, along the first direction a, the auxiliary light-shielding portion 62 of one of two adjacent pixel units 5 and the auxiliary light-shielding portion 62 of its nearest other pixel unit 5 can be spaced apart or connected. Furthermore, along the second direction b, the orthographic projection of the auxiliary light-shielding portion 62 onto the substrate 1 is continuous; or, along the second direction b, the orthographic projection of the auxiliary light-shielding portion 62 onto the substrate 1 is disconnected from each other at the boundary of each pixel unit 5.

[0077] Example 2 like Figure 5 and Figure 6 As shown, the privacy display panel in this embodiment is largely the same as the privacy display panel in Embodiment 1, except that the auxiliary light-shielding part 62 in this embodiment is not continuous.

[0078] In this embodiment, along the second direction b, the auxiliary light-shielding portion 62 includes a first light-shielding block 621 and a second light-shielding block 622 spaced apart. The third display sub-pixel 53 has first light-shielding blocks 621 on both opposite sides in the first direction a, and these blocks are spaced apart from the orthographic projection of the auxiliary light-shielding portion 62 onto the substrate 1. The first display sub-pixel 51 and the second display sub-pixel 52 both have second light-shielding blocks 622 on the side of the first display sub-pixel 51 and the side away from the privacy sub-pixel 54 in the first direction a, and these blocks are spaced apart from the orthographic projection of the second light-shielding blocks 622 onto the substrate 1.

[0079] It is understood that within the same pixel unit 5, along the first direction a, the first light-blocking block 621 includes a first light-blocking strip 6211 and a second light-blocking strip 6212. The first light-blocking strip 6211 is located on one side of the third display sub-pixel 53, and the second light-blocking strip 6212 is located on the other side of the third display sub-pixel 53. In adjacent pixel units 5: the first light-blocking strip 6211 of one pixel unit 5 is arranged adjacent to the second light-blocking strip 6212 of another pixel unit 5, and the first light-blocking strip 6211 and the second light-blocking strip 6212 can be connected or spaced apart.

[0080] Accordingly, within the same pixel unit 5, along the first direction a, the second light-shielding block 622 includes a third light-shielding strip 6221 and a fourth light-shielding strip 6222. The third light-shielding strip 6221 is located on the side of the first display sub-pixel 51 away from the privacy sub-pixel 54, and the fourth light-shielding strip 6222 is located on the side of the second display sub-pixel 52 away from the privacy sub-pixel 54. In adjacent pixel units 5: the third light-shielding strip 6221 of one pixel unit 5 is arranged adjacent to the fourth light-shielding strip 6222 of another pixel unit 5, and the third light-shielding strip 6221 and the fourth light-shielding strip 6222 can be connected or spaced apart.

[0081] Furthermore, along the second direction b: the opposite sides of the orthographic projection of the privacy shield 61 on the substrate 1 are respectively provided to protrude from the opposite sides of the orthographic projection of the first display sub-pixel 51 and the second display sub-pixel 52 on the substrate 1.

[0082] The first light-shielding block 621 is positioned so that its two sides protrude from the opposite sides of the third display sub-pixel 53 on the substrate 1; the second light-shielding block 622 is positioned so that its two sides protrude from the opposite sides of the first display sub-pixel 51 and the second display sub-pixel 52 on the substrate 1.

[0083] It is understandable that if the first light-shielding strip 6211 and the third light-shielding strip 6221 are located on the same side, and the second light-shielding strip 6212 and the fourth light-shielding strip 6222 are located on the same side: the first light-shielding strip 6211 is set to protrude along the second direction b on the side away from the third light-shielding strip 6221 relative to the side of the third display sub-pixel 53; the first light-shielding strip 6211 is set to protrude along the second direction b on the side closer to the third light-shielding strip 6221 relative to the other side of the third display sub-pixel 53; the second light-shielding strip 6212 is set to protrude along the second direction b on the side away from the fourth light-shielding strip 6222 relative to the side of the third display sub-pixel 53; and the second light-shielding strip 6212 is set to protrude along the second direction b on the side closer to the fourth light-shielding strip 6222 relative to the other side of the third display sub-pixel 53. The third light-shielding strip 6221 is arranged to protrude along the second direction b on the side away from the first display sub-pixel 51. The third light-shielding strip 6221 is arranged to protrude along the second direction b on the side closer to the first light-shielding strip 6211 on the other side of the first display sub-pixel 51. The fourth light-shielding strip 6222 is arranged to protrude along the second direction b on the side away from the second light-shielding strip 6212 on the other side of the second display sub-pixel 52. The fourth light-shielding strip 6222 is arranged to protrude along the second direction b on the side closer to the second light-shielding strip 6212 on the other side of the second display sub-pixel 52.

[0084] In this embodiment, along the second direction b: the distance between the opposite sides of the orthographic projection of the first light-shielding block 621 on the substrate 1 and the opposite sides of the third display sub-pixel 53 is the first distance h1; that is, the distance between the first light-shielding strip 6211 and the second light-shielding strip 6212 protruding relative to the opposite sides of the third display sub-pixel 53 along the second direction b is the first distance h1.

[0085] The distances between the opposite sides of the orthographic projection of the second light-shielding block 622 on the substrate 1 and the opposite sides of the orthographic projections of the first display sub-pixel 51 and the second display sub-pixel 52 on the substrate 1 are both the second distance h2; that is, the distances between the third light-shielding strip 6221 and the opposite sides of the first display sub-pixel 51 along the second direction b, and the distances between the fourth light-shielding strip 6222 and the opposite sides of the second display sub-pixel 52 along the second direction b, are the second distance h2. The distances between the privacy light-shielding portion 61 and the opposite sides of the privacy sub-pixel 54 along the second direction b are less than h2.

[0086] In this embodiment, the first distance h1 and the second distance h2 are equal, and their range is less than or equal to 25 μm. For example, the values ​​of the first distance h1 and the second distance h2 are 5 μm, 5.6 μm, 6.5 μm, 7.1 μm, 8.2 μm, 9.7 μm, 10 μm, 11 μm, or 12.5 μm, etc.

[0087] Furthermore, along the second direction b: in two adjacent pixel units 5, the first light-shielding strip 6211 of one pixel unit 5 and the third light-shielding strip 6221 of another pixel unit 5 can also be spaced apart, and the second light-shielding strip 6212 of one pixel unit 5 and the fourth light-shielding strip 6222 of another pixel unit 5 can also be spaced apart.

[0088] Of course, in other embodiments, along the second direction b: in two adjacent pixel units 5, the first light-shielding strip 6211 of one pixel unit 5 and the third light-shielding strip 6221 of another pixel unit 5 may also be connected, and the second light-shielding strip 6212 of one pixel unit 5 and the fourth light-shielding strip 6222 of another pixel unit 5 may also be connected.

[0089] For other structures of the privacy display panel light, please refer to Embodiment 1, which will not be repeated here.

[0090] Example 3 like Figure 7 and Figure 8 As shown, the privacy display panel in this embodiment is largely the same as that in Embodiment 1, except that one side of the third display sub-pixel 53 in this embodiment is not aligned with the side of the first display sub-pixel 51 away from the privacy sub-pixel 54; the other side of the third display sub-pixel 53 is not aligned with the side of the second display sub-pixel 52 away from the privacy sub-pixel 54. Therefore, the design of the corresponding auxiliary light-shielding part 62 is different.

[0091] In this embodiment, the edges of the first display sub-pixel 51 and the second display sub-pixel 52 on the side away from the privacy sub-pixel 54 in the first direction a are offset from the edge of the adjacent third display sub-pixel 53. Correspondingly, the auxiliary light-shielding part 62 includes a first light-shielding block 621 and a second light-shielding block 622, which are offset from each other along the first direction a.

[0092] Furthermore, the third display sub-pixel 53 has a first light-shielding block 621 on each of its opposite sides in the first direction a, and is spaced from the orthogonal projection of the auxiliary light-shielding part 62 on the substrate 1. The first display sub-pixel 51 and the second display sub-pixel 52 both have a second light-shielding block 622 on the side of the first display sub-pixel 51 away from the privacy sub-pixel 54 in the first direction a, and are spaced from the orthogonal projection of the second light-shielding block 622 on the substrate 1.

[0093] It is understandable that, due to the different arrangement and area occupied by the first display sub-pixel 51, the second display sub-pixel 52, the third display sub-pixel 53, and the privacy sub-pixel 54, it may be possible that one side of the third display sub-pixel 53 along the first direction a is not aligned with the side of the first display sub-pixel 51 away from the privacy sub-pixel 54, and the other side of the third display sub-pixel 53 is not aligned with the side of the second display sub-pixel 52 away from the privacy sub-pixel 54.

[0094] At this time, by setting the first light-blocking block 621 and the second light-blocking block 622 to be staggered along the first direction a, it can be ensured that the first spacing d1, the second spacing d2 and the third spacing d3 are also equal.

[0095] It is understood that, along the first direction a, within the same pixel unit 5: the first light-blocking block 621 includes a first light-blocking strip 6211 and a second light-blocking strip 6212, the first light-blocking strip 6211 is located on one side of the third display sub-pixel 53 and close to the first display sub-pixel 51, and the second light-blocking strip 6212 is located on the other side of the third display sub-pixel 53 and close to the second display sub-pixel 52; the second light-blocking block 622 includes a third light-blocking strip 6221 and a fourth light-blocking strip 6222, the third light-blocking strip 6221 is located on the side of the first display sub-pixel 51 away from the privacy sub-pixel 54, and the fourth light-blocking strip 6222 is located on the side of the second display sub-pixel 52 away from the privacy sub-pixel 54.

[0096] For example, when the side of the first sub-pixel protrudes from the side of the third display sub-pixel 53 closest to the first sub-pixel along the first direction a, the first light-shielding strip 6211 and the third light-shielding strip 6221 are misaligned, and the distance between the first light-shielding strip 6211 and the second light-shielding strip 6212 is smaller than the distance between the third light-shielding strip 6221 and the fourth light-shielding strip 6222.

[0097] Furthermore, since each pixel unit 5 occupies the same area, and one side of the third display sub-pixel 53 is not aligned with the side of the first display sub-pixel 51 away from the privacy sub-pixel 54, and the other side of the third display sub-pixel 53 is not aligned with the side of the second display sub-pixel 52 away from the privacy sub-pixel 54, in adjacent pixel units 5: to ensure that the widths of the first light-shielding strip 6211, the second light-shielding strip 6212, the third light-shielding strip 6221, and the fourth light-shielding strip 6222 along the first direction a are all the same, the first light-shielding strip 6211 of one pixel unit 5 and the third light-shielding strip 6221 of another pixel unit 5 can be spaced apart, and the second light-shielding strip 6212 of one pixel unit 5 and the fourth light-shielding strip 6222 of another pixel unit 5 can also be spaced apart.

[0098] For other structures of the privacy display panel light, please refer to Embodiment 1 and / or Embodiment 2, which will not be repeated here.

[0099] Example 4 like Figure 9 and Figure 10 As shown, the privacy display panel in this embodiment is largely the same as the privacy display panel in embodiment three, except that the widths of the first light-blocking block 621 and the second light-blocking block 622 in the first direction a are different.

[0100] In this embodiment, the edges of the first display sub-pixel 51 and the second display sub-pixel 52 on the side away from the privacy sub-pixel 54 in the first direction a are offset from the edge of the adjacent third display sub-pixel 53. Correspondingly, the auxiliary light-shielding part 62 includes a first light-shielding block 621 and a second light-shielding block 622, which are offset from each other along the first direction a.

[0101] Furthermore, the third display sub-pixel 53 has a first light-shielding block 621 on each of its opposite sides in the first direction a, and is spaced from the orthogonal projection of the auxiliary light-shielding part 62 on the substrate 1. The first display sub-pixel 51 and the second display sub-pixel 52 both have a second light-shielding block 622 on the side of the first display sub-pixel 51 away from the privacy sub-pixel 54 in the first direction a, and are spaced from the orthogonal projection of the second light-shielding block 622 on the substrate 1.

[0102] It is understandable that, due to the different arrangement and area occupied by the first display sub-pixel 51, the second display sub-pixel 52, the third display sub-pixel 53, and the privacy sub-pixel 54, it may be possible that one side of the third display sub-pixel 53 along the first direction a is not aligned with the side of the first display sub-pixel 51 away from the privacy sub-pixel 54, and the other side of the third display sub-pixel 53 is not aligned with the side of the second display sub-pixel 52 away from the privacy sub-pixel 54.

[0103] At this time, by setting the first light-blocking block 621 and the second light-blocking block 622 to be staggered along the first direction a, it can be ensured that the first spacing d1, the second spacing d2 and the third spacing d3 are also equal.

[0104] It is understood that, along the first direction a, within the same pixel unit 5: the first light-blocking block 621 includes a first light-blocking strip 6211 and a second light-blocking strip 6212, the first light-blocking strip 6211 is located on one side of the third display sub-pixel 53 and close to the first display sub-pixel 51, and the second light-blocking strip 6212 is located on the other side of the third display sub-pixel 53 and close to the second display sub-pixel 52; the second light-blocking block 622 includes a third light-blocking strip 6221 and a fourth light-blocking strip 6222, the third light-blocking strip 6221 is located on the side of the first display sub-pixel 51 away from the privacy sub-pixel 54, and the fourth light-blocking strip 6222 is located on the side of the second display sub-pixel 52 away from the privacy sub-pixel 54.

[0105] For example, when the side of the first sub-pixel protrudes from the side of the third display sub-pixel 53 closest to the first sub-pixel along the first direction a, the first light-shielding strip 6211 and the third light-shielding strip 6221 are misaligned, and the distance between the first light-shielding strip 6211 and the second light-shielding strip 6212 is smaller than the distance between the third light-shielding strip 6221 and the fourth light-shielding strip 6222.

[0106] In this embodiment, in two adjacent pixel units 5: along the first direction a, the side of the first light-shielding block 621 of one pixel unit 5 is connected to the side of the first light-shielding block 621 adjacent to another pixel unit 5, and the side of the second light-shielding block 622 of one pixel unit 5 is connected to the side of the second light-shielding block 622 adjacent to another pixel unit 5.

[0107] It is understandable that, since each pixel unit 5 occupies the same area, and one side of the third display sub-pixel 53 is not aligned with the side of the first display sub-pixel 51 away from the privacy sub-pixel 54, and the other side of the third display sub-pixel 53 is not aligned with the side of the second display sub-pixel 52 away from the privacy sub-pixel 54, in adjacent pixel units 5: to ensure that the widths of the first light-blocking strip 6211, the second light-blocking strip 6212, the third light-blocking strip 6221, and the fourth light-blocking strip 6222 along the first direction a are all the same, wherein the first light-blocking strip 6211 of one pixel unit 5 is connected to the third light-blocking strip 6221 of another pixel unit 5, and the second light-blocking strip 6212 of one pixel unit 5 is connected to the fourth light-blocking strip 6222 of another pixel unit 5. At this time, the widths of the first light-blocking block 621 and the second light-blocking block 622 are different in the first direction a.

[0108] Example 5 like Figure 11 and Figure 12 As shown, the privacy display panel in this embodiment is largely the same as the privacy display panel in Embodiment 1, except that the auxiliary light-shielding part 62 in this embodiment is a whole surface.

[0109] In this embodiment, the auxiliary light-shielding part 62 is provided on the entire surface. By providing a plurality of arrayed openings 101 on the auxiliary light-shielding part 62, the first display sub-pixel 51, the second display sub-pixel 52, the third display sub-pixel 53 and the privacy sub-pixel 54 of each pixel unit 5 are exposed from the corresponding openings 101.

[0110] Understandably, the area of ​​the opening 101 of the auxiliary light-shielding part 62 is larger than the areas of the corresponding exposed first display sub-pixel 51, second display sub-pixel 52, third display sub-pixel 53, and privacy sub-pixel 54. In other words, the orthographic projection of the auxiliary light-shielding part 62 on the substrate 1 is spaced apart from the orthographic projections of the first display sub-pixel 51, second display sub-pixel 52, third display sub-pixel 53, and privacy sub-pixel 54 to avoid affecting the light-emitting effect.

[0111] Example 6 The second aspect of this application discloses a display device, including a housing and the aforementioned privacy display panel, wherein the privacy display panel is connected to the housing.

[0112] In this embodiment, the display device includes a laptop computer, a vehicle display, an electronic billboard, or a mobile phone, etc.
