[0024] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. The described technical solutions are only used to explain and illustrate the ideas of the present application and should not be regarded as limiting the scope of protection of the present application.

[0025] In the description of this application, it should be understood that the terms "first", "second" and similar words do not indicate any order, quantity or importance, but are only used to distinguish different technical features. The term "plurality" and similar words mean two or more, unless otherwise clearly defined.

[0026] In this application, the word "exemplary" is used to mean "serving as an example, illustration, or description." Any embodiment described as "exemplary" in this application is not necessarily to be construed as being preferred or advantageous over other embodiments. The following description is provided to enable any person skilled in the art to implement and use the present application.

[0027] The various embodiments of the present application are similar, and features in different embodiments may be combined with each other.

[0028] With the increasing popularity and application of display devices, users pay more and more attention to the protection of personal information, so the anti-peeping function is increasingly valued by users. In order to be applicable to other usage scenarios, the display device also needs to have a normal viewing angle display function. Therefore, in order to meet the user's demand for the display device in different scenarios, it is necessary to provide a display device with an anti-peeping function and a normal viewing angle display function, and the two can be flexibly switched.

[0029] In the related art, a display device with an anti-peep film attached cannot realize a normal viewing angle display function. To realize the normal viewing angle display function, the anti-peep film needs to be torn off, thus affecting the user experience.

[0030] Based on this, some embodiments disclosed in this application provide a display device, such as Figure 1 The display device 100 includes a display panel 10 , an anti-peeping component 20 , a backlight module 30 , a bottom polarizer 41 , a first polarizer 42 and a second polarizer 43 .

[0031] The display panel 10 includes: a bottom substrate 11, a top substrate 16 disposed opposite to the bottom substrate 11, and a second liquid crystal layer 14 disposed between the bottom substrate 11 and the top substrate 16. A pixel layer 12 is disposed on the bottom substrate 11, and a black matrix layer 13 and a common electrode layer 15 are disposed on the top substrate 16. The black matrix layer 13 can be disposed between the top substrate 16 and the common electrode layer 15. The pixel layer 12 includes a plurality of pixel electrodes 121. By adjusting the voltage difference between the pixel electrode 121 and the common electrode layer 15, it is possible to control whether the liquid crystal molecules in the second liquid crystal layer 14 are deflected, and further control whether the pixel corresponding to the pixel electrode 121 emits light. In this way, the display of the display panel 10 can be realized.

[0032] The bottom polarizer 41 is disposed between the display panel 10 and the backlight module 30. For example, the bottom polarizer 41 can be disposed on the surface of the light incident side of the display panel 10.

[0033] The first polarizer 42 is disposed on the surface of the light-emitting side of the display panel 10, and the polarization direction of the first polarizer 42 is perpendicular to the polarization direction of the bottom polarizer 41, that is, the light transmission axis of the first polarizer 42 is perpendicular to the light transmission axis of the bottom polarizer 41. In this way, by determining whether the liquid crystal molecules in the second liquid crystal layer 14 are deflected, the propagation direction of the light passing through the liquid crystal molecules can be adjusted, thereby realizing whether the pixel corresponding to the pixel electrode 121 emits light.

[0034] The anti-peeping component 20 includes: a first electrode layer 22, a first liquid crystal layer 23, and a first substrate 25, which are arranged in sequence on the side of the top substrate 16 away from the bottom substrate 11. A second electrode layer 24 is arranged on the first substrate 25. A second polarizer 43 is arranged on the first substrate 25, and the polarization direction of the second polarizer 43 is the same as that of the first polarizer 42. In this embodiment, the second electrode layer 24 and the second polarizer 43 are arranged on both sides of the first substrate 25.

[0035] The black matrix layer 13 includes a plurality of first light-transmitting gaps 132, the first electrode layer 22 includes a plurality of second light-transmitting gaps 222, and the second electrode layer 24 includes a plurality of third light-transmitting gaps 242. Along the thickness direction of the base substrate 11, one first light-transmitting gap 132, one second light-transmitting gap 222, and one third light-transmitting gap 242 are correspondingly arranged, and together expose one pixel electrode 121. For example, the orthographic projections of one first light-transmitting gap 132, one second light-transmitting gap 222, and one third light-transmitting gap 242 on the base substrate 11 have an overlapping region P, and the orthographic projection of one pixel electrode 121 on the base substrate 11 is located within the overlapping region P.

[0036] In some examples, the first electrode layer 22 includes a first electrode 221 , and the area other than the first electrode 221 is the second light-transmitting gap 222 ; the second electrode layer 24 includes a second electrode 241 , and the area other than the second electrode 241 is the third light-transmitting gap 242 .

[0037] For the above display device 100, when there is no voltage difference between the first electrode layer 22 and the second electrode layer 24, as shown in FIG. Figure 2 As shown, all liquid crystal molecules in the first liquid crystal layer 23 (including some liquid crystal molecules 231 between the first electrode 221 and the second electrode 241) stand vertically, so that the linear light passing through the first polarizer will not be deflected after passing through the first liquid crystal layer 23, and can continue to propagate through the second polarizer 43. In this case, whether the user 300 is at the normal viewing angle or the user 301 is at the side viewing angle (oblique viewing angle), they can all receive the light emitted from the display device 100 (such as Figure 2 As shown by the solid line with an arrow in the middle, the direction indicated by the arrow is the propagation direction of the light), so as to watch the picture displayed on the display device 100. At this time, the display device 100 is in a normal viewing angle display state, that is, the display device 100 is in a shared state.

[0038] When there is a voltage difference between the first electrode layer 22 and the second electrode layer 24, such as Figure 3 As shown, part of the liquid crystal molecules 231 between the first electrode 221 and the second electrode 241 in the first liquid crystal layer 23 tilt under the action of the electric field, so that the propagation direction of the linear light passing through the first polarizer 42 is deflected after passing through the part of the liquid crystal molecules 231, resulting in the linear light being unable to pass through the second polarizer 43. At this time, the user 300 at the normal viewing angle position can receive the light emitted from the display device 100, while the user 301 at the side viewing angle (oblique viewing angle) position cannot receive the light emitted from the display device 100. In this way, the purpose of preventing surrounding users from peeping at the content displayed on the display device 100 can be achieved, and the display device 100 is in an anti-peeping state.

[0039] It is worth noting that the liquid crystal molecules 231 may be negative liquid crystal molecules or positive liquid crystal molecules, which is not limited in the embodiments of the present application.

[0040] Therefore, the display device 100 provided in the embodiment of the present application can flexibly switch between the anti-peeping state and the normal viewing angle display state, thereby improving the user experience.

[0041] In addition, since the pixel electrode 121 is located in the overlapping area P, it can be ensured that the display device 100 has sufficient positive viewing angle light regardless of the anti-peeping state or the shared state, thereby ensuring normal use by the user. In addition, the anti-peeping component 20 can be directly manufactured on the display panel 10 in sequence, so that the thickness of the display device 100 can be reduced, which is conducive to further improving the user experience.

[0042] In some embodiments, Figure 1 As shown, the display device 100 further includes a color resist layer 131, the color resist layer includes a plurality of color resist blocks, each of which is located in a first light-transmitting gap 132 of the black matrix layer 13. For example, the plurality of color resist blocks may include a red color resist block, a blue color resist block, and a green color resist block. By providing the color resist layer, the color display of the display device 100 can be achieved.

[0043] In some examples, each of the plurality of first light-transmitting gaps 132 overlaps with a corresponding second light-transmitting gap 222 and a corresponding third light-transmitting gap 242, and the orthographic projections of the three on the base substrate 11 together form an overlapping region P, and there is always one pixel electrode 121 among the plurality of pixel electrodes 121 located within the overlapping region P.

[0044] In some examples, the number of the first light-transmitting gaps 132 , the second light-transmitting gaps 222 , and the third light-transmitting gaps 242 are equal and correspond one to one.

[0045] In some embodiments, Figure 4 As shown, the orthographic projection of the first light-transmitting gap 132 on the base substrate 11 coincides with the overlapping region P. That is, the edge of the orthographic projection of the first light-transmitting gap 132 on the base substrate 11 coincides with the boundary of the overlapping region P. In this case, the second light-transmitting gap 222 of the first electrode layer 22 and the third light-transmitting gap 242 of the second electrode layer 24 may be larger than the overlapping region P, so that the setting area of ​​the first electrode 221 or the second electrode 241 may be flexibly arranged as needed.

[0046] In some examples, the first electrode layer 22 includes a plurality of first electrodes 221 arranged side by side, and the extension direction of each first electrode 221 is perpendicular to the above-mentioned side-by-side direction. In this case, the first electrodes 221 are arranged in strips. The orthographic projection of each first electrode 221 on the base substrate 11 is located within the range of the orthographic projection of the black matrix layer 13 on the base substrate 11.

[0047] In some examples, the second electrode layer 24 includes a plurality of second electrodes 241 corresponding one-to-one to the plurality of first electrodes 221 , and an orthographic projection of each second electrode 241 on the base substrate 11 overlaps with an orthographic projection of a corresponding first electrode 221 on the base substrate 11 .

[0048] In some embodiments, Figure 1 as well as Figures 5 to 7 As shown, the edge of the first light-transmitting gap 132, the edge of the second light-transmitting gap 222, and the edge of the third light-transmitting gap 242 are all aligned. In this case, the orthographic projections of the first light-transmitting gap 132, the second light-transmitting gap 222, and the third light-transmitting gap 242 coincide with the overlapping area P, respectively. Therefore, the shapes and sizes of the first light-transmitting gap 132, the second light-transmitting gap 222, and the third light-transmitting gap 242 are respectively consistent, that is, the shapes and sizes of the first electrode layer 22, the second electrode layer 24, and the black matrix layer 13 are respectively consistent. In this way, all the liquid crystal molecules 231 directly above the black matrix layer 13 can be driven to tilt, thereby improving the dark state effect, thereby improving the anti-peeping quality of the display device 100.

[0049] In some embodiments, Figure 1 As shown, the edge of the pixel electrode 121 is at least partially aligned with the edge of the light-transmitting gap 132 , that is, the edge of the orthographic projection of the first pixel electrode 121 on the base substrate 11 and the boundary of the overlapping area P at least partially overlap.

[0050] This arrangement can, on the one hand, prevent the black matrix layer 13, the first electrode layer 22 and the second electrode layer 24 from blocking the pixel electrode 121 in the vertical direction (i.e., the thickness direction of the base substrate 11), thereby effectively ensuring that the light emitted through the pixel electrode 121 can be well emitted; on the other hand, it can also increase the area of ​​the pixel electrode 121, so that more light can be emitted in the overlapping area P.

[0051] In some examples, the edge of the orthographic projection of the pixel electrode 121 on the base substrate 11 coincides with the boundary portion of the overlapping region P. Figure 1 As shown, part of the right edge of the pixel electrode 121 coincides with part of the right boundary of the overlapping region P.

[0052] In other examples, such as Figure 5 As shown, the edge of the orthographic projection of the pixel electrode 121 on the base substrate 11 completely coincides with the boundary of the overlapping region P. In this case, the shape and size of the pixel electrode 121 are respectively the same as those of the overlapping region P, which is beneficial to increase the light emission of the display device 100.

[0053] In some embodiments, Figure 6 and Figure 7As shown, the edge of the pixel electrode 121 and the edge of the first light-transmitting gap 132 are arranged in a staggered manner, that is, the edge of the orthographic projection of the pixel electrode 121 on the base substrate 11 is located in the overlapping area P. This can effectively prevent the overlapping area P from shrinking due to the problem of alignment accuracy during the installation of the anti-peeping component 20, thereby causing the pixel electrode 121 to partially exceed the overlapping area P. Therefore, by setting the edge of the pixel electrode 121 in the overlapping area P, it is helpful to ensure that the light emitted through the pixel electrode 121 can be well emitted.

[0054] In some examples, the edge of the orthographic projection of the pixel electrode 121 on the base substrate 11 includes multiple sub-edges, the boundary of the overlapping area P includes multiple sub-boundaries corresponding to the multiple sub-edges one by one, and the spacing between the multiple sub-edges and the corresponding sub-boundaries is equal. This is conducive to reducing the adverse effects of the above-mentioned alignment accuracy problem.

[0055] In some examples, the pixel electrodes and the common electrode of the common electrode layer 15 are both transparent electrodes, so that light can pass through effectively, thereby ensuring good display performance of the display panel 10 .

[0056] In some examples, alignment film layers are provided on both sides of the second liquid crystal layer 14. The alignment film layers can be used to make the liquid crystal molecules in the second liquid crystal layer 14 have a certain pre-tilt angle, so that the deflection speed of the liquid crystal molecules is faster, which is beneficial to improving the switching of the display panel 10 between the display state or the screen-off state.

[0057] In some embodiments, Figure 1 As shown, the anti-peeping component 20 further includes a second substrate 21 , and the first polarizer 42 and the first electrode layer 22 are located on both sides of the second substrate 21 .

[0058] This arrangement allows the anti-peeping component 20 to be manufactured separately, and also allows the anti-peeping component 20 and the display panel 10 to be manufactured simultaneously on different production lines, and then the two can be installed in alignment. This helps to improve the manufacturing efficiency of the display device 100.

[0059] In some embodiments, Figure 1 As shown, the anti-peeping component 20 further includes a first alignment film layer 26 located between the first liquid crystal layer 23 and the first electrode layer 22 , and a second alignment film layer 28 located between the first liquid crystal layer 23 and the second electrode layer 24 .

[0060] The liquid crystal molecules 231 in the first liquid crystal layer 23 can be aligned by using the first alignment film layer 26 and the second alignment film layer 28, so that the liquid crystal molecules 231 in the first liquid crystal layer 23 have a certain pre-tilt angle, thereby making the deflection speed of the liquid crystal molecules 231 faster, which is beneficial to improving the switching of the display device 100 between the anti-peeping state and the sharing state.

[0061] In some examples, the alignment film layer described herein may be made of PI (Polyimide) material.

[0062] In some examples, a plastic frame 27 may be further disposed between the first alignment film layer 26 and the second alignment film layer 28. The plastic frame 27 may be used to encapsulate the first liquid crystal layer 23 in the anti-peeping component 20, thereby ensuring the stability of the first liquid crystal layer 23.

[0063] It is worth mentioning that Figures 1 to 7 The shape of the pixel electrode 121 illustrated in the figure does not limit the actual shape of the pixel electrode 121 , and is only for the convenience of illustrating the area range of the corresponding pixel electrode 121 .

[0064] Some embodiments of the present application also provide a display device, such as Figure 8 As shown, the display device 200 includes: a display panel 10 , an anti-peeping component 20 , a first polarizer 42 and a second polarizer 43 .

[0065] The display panel 10 includes a base substrate 11, a pixel layer 12 disposed on the base substrate 11, and an encapsulation layer 17 disposed on the pixel layer 12. The first polarizer 42 is disposed on the encapsulation layer 17.

[0066] The anti-peeping component 20 includes a first electrode layer 22, a first liquid crystal layer 23 and a first substrate 25 which are sequentially arranged on the first polarizer 42, and a second electrode layer 24 is arranged on the first substrate 25. In this embodiment, the second electrode layer 24 can be arranged on a side of the first substrate 25 close to the first liquid crystal layer 23.

[0067] The second polarizer 43 is disposed on the first substrate 25 , and the polarization direction of the second polarizer 43 is the same as the polarization direction of the first polarizer 42 .

[0068] The pixel layer 12 includes a plurality of pixel units 122, the first electrode layer 22 includes a plurality of second light-transmitting gaps 222, and the second electrode layer 24 includes a plurality of third light-transmitting gaps 242. One second light-transmitting gap 222 and one third light-transmitting gap 242 are correspondingly arranged, and jointly expose one pixel unit 122. That is, the orthographic projections of one second light-transmitting gap 222 and one third light-transmitting gap 242 on the base substrate 11 have an overlapping area, and the orthographic projection of one pixel unit 122 on the base substrate 11 is located in one overlapping area.

[0069] For the sake of distinction, in some embodiments or examples of the present application, the display device 100 is referred to as a first display device, and the display device 200 is referred to as a second display device.

[0070] For the above-mentioned display device 200 (i.e., the second display device), the working process of the anti-peeping state and the sharing state can refer to the description of the working process of the anti-peeping state and the sharing state of the display device 100 (i.e., the first display device), which will not be repeated here. Therefore, the display device 200 can flexibly switch between the anti-peeping state and the normal viewing angle display state (i.e., the sharing state), thereby improving the user's experience. In addition, since the pixel unit 122 is located in the overlapping area of ​​the second light-transmitting gap 222 and the third light-transmitting gap 242, it can be ensured that the display device 200 has good positive viewing angle light regardless of whether it is in the anti-peeping state or the sharing state, thereby ensuring the normal use of the user. In addition, the anti-peeping component 20 can be directly manufactured on the display panel 10 in sequence, so that the thickness of the display device 200 can be reduced, which is conducive to further improving the user's experience.

[0071] In some embodiments, Figure 8 As shown, the display panel 10 further includes a black matrix layer 13, the black matrix layer 13 is located between the first polarizer 42 and the encapsulation layer 17, and the black matrix layer 13 includes a plurality of first light-transmitting gaps 132, a first light-transmitting gap 132, a second light-transmitting gap 222, and a third light-transmitting gap 242 are correspondingly arranged and jointly expose the above-mentioned pixel unit 122. That is, the orthographic projections of the first light-transmitting gap 132, the second light-transmitting gap 222, and the third light-transmitting gap 242 on the base substrate 11 have an overlapping area P, and the orthographic projections of the above-mentioned pixel unit 122 on the base substrate 11 are located in an overlapping area P.

[0072] In this arrangement, since the pixel unit 122 is located in the overlapping area P of the first light-transmitting gap 132, the second light-transmitting gap 222 and the third light-transmitting gap 242, it can be ensured that the display device 200 has sufficient positive viewing angle light regardless of whether it is in the anti-peeping state or the sharing state, thereby ensuring normal use by the user.

[0073] In some examples, such as Figure 8 As shown, the pixel unit 122 may include a driving circuit and a light-emitting device electrically connected to the driving circuit, and the driving circuit is used to drive the light-emitting device electrically connected thereto to emit light.

[0074] In some examples, the light-emitting device may be a Micro LED (Micro Light-Emitting Diode), a Mini LED (Mini Light-Emitting Diode) or an OLED (Organic Light-Emitting Diode), and this application does not limit it. It is worth noting that when different light-emitting devices are used, the components related to or essential to the light-emitting device are not described in detail herein, and the specific configuration can be made with reference to the existing Micro LED, Mini LED or OLED.

[0075] In some embodiments, when the light-emitting device is a Micro LED or a Mini LED, the display panel 10 may further include an optical film layer located between two adjacent light-emitting devices, and the encapsulation layer 17 covers both the light-emitting device and the optical film layer.

[0076] In some examples, the optical film layer may include white ink, which can reflect the light emitted by the light-emitting device, thereby increasing the light output of the display panel 10 .

[0077] In other examples, the optical film layer may be made of a black light-absorbing material, so that the light emitted by the light-emitting device and directed toward the base substrate 11 can be absorbed, thereby improving the contrast of the display panel 10 .

[0078] In some embodiments, Figure 4 As shown, the orthographic projection of the first light-transmitting gap 132 on the base substrate 11 coincides with the overlapping region P. That is, the edge of the orthographic projection of the first light-transmitting gap 132 on the base substrate 11 coincides with the boundary of the overlapping region P. In this case, the second light-transmitting gap 222 of the first electrode layer 22 and the third light-transmitting gap 242 of the second electrode layer 24 may be larger than the overlapping region P, so that the setting area of ​​the first electrode 221 or the second electrode 241 may be flexibly arranged as needed.

[0079] In some embodiments, Figure 7As shown, the edge of the first light-transmitting gap 132, the edge of the second light-transmitting gap 222, and the edge of the third light-transmitting gap 242 are all aligned. In this case, the orthographic projections of the first light-transmitting gap 132, the second light-transmitting gap 222, and the third light-transmitting gap 242 coincide with the overlapping area P, respectively. Therefore, the shapes and sizes of the first light-transmitting gap 132, the second light-transmitting gap 222, and the third light-transmitting gap 242 are respectively consistent, that is, the shapes and sizes of the first electrode layer 22, the second electrode layer 24, and the black matrix layer 13 are respectively consistent. In this way, all the liquid crystal molecules 231 directly above the black matrix layer 13 can be driven to tilt, thereby improving the dark state effect, thereby improving the anti-peeping quality of the display device 200.

[0080] In some embodiments, Figure 8 As shown, the edge of the pixel unit 122 is at least partially aligned with the edge of the light-transmitting gap 132 , that is, the edge of the orthographic projection of the first pixel unit 122 on the base substrate 11 and the boundary of the overlapping area P at least partially overlap.

[0081] This arrangement can, on the one hand, prevent the black matrix layer 13, the first electrode layer 22 and the second electrode layer 24 from blocking the pixel unit 122 in the vertical direction (i.e., the thickness direction of the base substrate 11), thereby effectively ensuring that the light emitted through the pixel unit 122 can be well emitted; on the other hand, it can also increase the area of ​​the pixel unit 122, so that more light can be emitted from the overlapping area P.

[0082] In some examples, the edge of the orthographic projection of the pixel unit 122 on the base substrate 11 coincides with the boundary portion of the overlapping region P. Figure 8 As shown, part of the right edge of the pixel unit 122 coincides with part of the right boundary of the overlapping area P.

[0083] In other examples, such as Fig. 9 As shown, the edge of the orthographic projection of the pixel unit 122 on the base substrate 11 completely coincides with the boundary of the overlapping region P. In this case, the shape and size of the pixel unit 122 are respectively the same as those of the overlapping region P, which is beneficial to increase the light emission of the display device 200.

[0084] In some embodiments, Figure 7As shown, the edge of the pixel unit 122 is staggered with the edge of the first light-transmitting gap 132, that is, the edge of the orthographic projection of the pixel unit 122 on the base substrate 11 is located in the overlapping area P. This can effectively prevent the overlapping area P from shrinking due to the problem of alignment accuracy during the installation of the anti-peeping component 20, thereby causing the pixel unit 122 to partially exceed the overlapping area P. Therefore, by setting the edge of the pixel unit 122 in the overlapping area P, it is helpful to ensure that the light emitted through the pixel unit 122 can be well emitted.

[0085] In some embodiments, Figure 8 As shown, the display panel 10 further includes a top substrate 16 , and the black matrix layer 13 is disposed on the top substrate 16 ; the anti-peeping component 20 further includes a second substrate 21 , and the first polarizer 42 and the first electrode layer 22 are located on both sides of the second substrate 21 .

[0086] This arrangement allows the anti-peeping component 20 to be manufactured separately, and also allows the anti-peeping component 20 to be manufactured simultaneously with the display panel 10 on different production lines, and then the two can be aligned and installed. Since the black matrix layer 13 is arranged on the top substrate 16, this is conducive to the alignment of the anti-peeping component 20 and the display panel 10. Therefore, the manufacturing efficiency of the display device 200 can be effectively improved.

[0087] It is worth mentioning that Figure 8 and Fig. 9 The shape of the pixel unit 122 illustrated in the figure does not limit the actual shape of the pixel unit 122 , but is only for the convenience of illustrating the area range of the corresponding pixel unit 122 .
