[0002] In order to achieve the anti-peeping function during use, some existing display panels are equipped with an anti-peeping film inside, which limits the light emission direction of the screen through an ultra-fine shutter-like grid structure to reduce the brightness at a wide viewing angle. However, this type of anti-peeping function is achieved through a hardware anti-peeping film, and the strength cannot be adjusted or turned off, resulting in the display panel being unable to switch between the anti-peeping state and the shared state, and the flexibility is poor. The structural form that combines the collimated backlight and the anti-peeping screen has a poor display effect in the shared state.

[0003] Therefore, there is an urgent need for a display panel that can flexibly switch between a sharing state and an anti-peeping state, and a corresponding display device. Summary of the invention

[0007] The display panel can switch between an anti-peeping state and a sharing state. In the sharing state, the refractive index of the liquid crystal layer is greater than the refractive index of the dimming structure layer, and the difference is greater than 0.1. In the anti-peeping state, the difference between the refractive index of the liquid crystal layer and the refractive index of the dimming structure layer is less than or equal to 0.1.

The first and second substrate components are respectively provided with a first electrode layer and a second electrode layer. An electric field can be formed between the two electrode layers and drive the liquid crystal molecules in the liquid crystal layer to deflect, thereby changing the refractive index of the liquid crystal layer to achieve switching between a shared state and an anti-peeping state. A dimming structure layer is provided in the first substrate component. In the shared state, the refractive index of the liquid crystal layer is greater than the refractive index of the dimming structure layer.

For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0036] The features and exemplary embodiments of various aspects of the present application will be described in detail below.In addition, the features, structures, or characteristics described below may be combined in any suitable manner in one or more embodiments.

[0037] With the development of display technology and the popularization of display devices, users' demand for anti-peeping function of display panels is gradually increasing. Existing display devices usually adopt the method of attaching anti-peeping film or combining collimated backlight with anti-peeping screen to achieve anti-peeping. That is, when displaying, it will be possible to limit the light output angle of the display device so that the angle between it and the direction perpendicular to the light output surface is within a certain range, reducing the possibility of others other than the user viewing the displayed content from the side.

[0038] On this basis, the inventors found that in display devices with attached privacy films, the privacy films usually adopt a structure similar to a louver grid, with multiple ultra-fine slits to limit the direction of the emitted light. The privacy films are usually bonded to the display screen, which is not convenient for repeated connection and removal, resulting in the display device being unable to switch between the privacy state and the shared state. The display device using a collimated backlight and a privacy screen has the problem of poor display effect at a large viewing angle in the shared state, similar to the privacy film.

[0039] In order to solve the above technical problems, the embodiments of the present application provide a display panel and a display device, which can conveniently switch between an anti-peeping state and a sharing state, and can also improve the display effect in the sharing state.

[0040] Further, in order to better understand the present application, Figures 1 to 13 The display panel and the display device provided in the embodiments of the present application are described in detail.

[0041] Please also read Figures 1 to 3 , Figure 1 is a schematic diagram of the structure of a display panel provided by an embodiment of the present application, Figure 2 is a schematic diagram of the structure of an anti-peeping component provided by an embodiment of the present application, Figure 3 It is a structural schematic diagram of an anti-peeping component provided in another embodiment of the present application.

[0042] In a first aspect, an embodiment of the present application provides a display panel 100, including a stacked display component 10 and an anti-peeping component 20, wherein the anti-peeping component 20 includes a first substrate component 21, a second substrate component 22, and a liquid crystal layer 23 located between the first substrate component 21 and the second substrate component 22; wherein the first substrate component 21 includes a first substrate 211, a dimming structure layer 212, and a first electrode layer 213 stacked in sequence, the second substrate component 22 includes a second substrate 221 and a second electrode layer 222 stacked in sequence, and the first substrate component 21 includes a first substrate 211, a dimming structure layer 212, and a first electrode layer 213 stacked in sequence, and the second substrate component 22 includes a second substrate 221 and a second electrode layer 222 stacked in sequence. An electrode layer 213 is arranged opposite to the second electrode layer 222, and an extension direction of at least a portion of the surface of the dimming structure layer 212 facing the first electrode layer 213 intersects with an extension direction of the surface of the first substrate 211; the display panel 100 can switch between an anti-peeping state and a sharing state. In the sharing state, the refractive index of the liquid crystal layer 23 is greater than the refractive index of the dimming structure layer 212, and the difference is greater than 0.1. In the anti-peeping state, the difference between the refractive index of the liquid crystal layer 23 and the refractive index of the dimming structure layer 212 is less than or equal to 0.1.

[0043] The embodiment of the present application provides a display panel 100, which includes a display component 10 for providing an image display function and an anti-peeping component 20 for providing a wide viewing angle anti-peeping function, which are stacked. The anti-peeping component 20 further includes a first substrate component 21 and a second substrate component 22 that are arranged opposite to each other, and a liquid crystal layer 23 accommodated therebetween, and the liquid crystal layer 23 can change the refractive index accordingly according to the intensity of the electric field applied thereto.

[0044] Furthermore, the first substrate assembly 21 includes a first substrate 211, a dimming structure layer 212, and a first electrode layer 213 which are stacked. The first substrate 211 may be a substrate with a high transmittance, such as glass or PI (Polyimide), the dimming structure layer 212 is used to adjust the refraction direction of light passing through the layer at the interface, and the first electrode layer 213 is used as a side electrode for forming an electric field. The dimming structure layer 212 may be made of a material with a high transmittance that is the same as the common material of the planarization layer, and the first electrode layer 213 and the second electrode layer 222 may be made of transparent metal oxide materials such as ITO (Indium Tin Oxides).

[0045] Correspondingly, the second substrate assembly 22 further includes a second substrate 221 and a second electrode layer 222 which are stacked. The material and thickness of the second substrate 221 can be the same as those of the first substrate 211 to facilitate processing. The first substrate 211 and the second substrate 221 can be arranged parallel to each other to form a liquid crystal layer 23 with uniform thickness between the two substrate assemblies. The second electrode is arranged opposite to the first electrode to form an electric field between the two that can act on the liquid crystal layer 23, thereby changing the overall refractive index of the liquid crystal layer 23 by changing the posture of the liquid crystal molecules.

[0046] Specifically, the first electrode and the second electrode are arranged opposite to each other, that is, the first electrode and the second electrode are arranged on the side of the first substrate 211 and the second substrate 221 close to each other, and the first electrode is arranged on the side of the dimming structure layer 212 facing the second electrode, thereby reducing the dimming structure layer 212 to reduce the blocking of the electric field between the first electrode and the second electrode, reducing the voltage required to drive the liquid crystal, and thus reducing the power consumption of the anti-peeping component 20. Either the first substrate assembly 21 or the second substrate assembly 22 can be arranged close to the display component 10, and the present application does not make any specific limitation here.

[0047] Optionally, the side surface of the dimming structure layer 212 facing the first electrode may be a curved surface or an inclined surface, that is, the extension direction of the side surface may at least partially intersect with the extension direction of the first substrate 211, for example, the dimming structure layer 212 is configured to include a plurality of microlens units or a plurality of prism units, etc., so that the collimated light in a specific state can be refracted at the side surface of the dimming structure layer 212 facing the first electrode to widen the light output angle. Here, the collimated light refers to the light whose transmission direction is parallel to the thickness direction Z of the display panel 100.

[0048] On this basis, by applying an electric signal to the first electrode layer 213 and the second electrode layer 222, an electric field can be formed between the two to deflect the liquid crystal molecules in the liquid crystal layer 23. Since the liquid crystal molecules have a birefringence characteristic, the refractive index of the liquid crystal layer 23 formed by them is affected by the relationship between the direction of light passing through and the position of the liquid crystal molecules. When the refractive index of the liquid crystal layer 23 is the long-axis refractive index of the liquid crystal molecules and when it is the short-axis refractive index, its value is different. Therefore, the refractive index of the liquid crystal layer 23 can be changed by deflecting the liquid crystal molecules to achieve switching between the anti-peeping state and the sharing state.

[0049] Specifically, in the shared state, an electric field is applied and the refractive index of the liquid crystal layer 23 is adjusted so that there is a large difference between it and the refractive index of the dimming structure layer 212, for example, a difference greater than 0.1. At this time, the collimated light passing through the dimming structure layer 212 can be refracted at the interface between the dimming structure layer 212 and the first electrode layer 213 and / or the interface between the first electrode layer 213 and the liquid crystal layer 23, and the outgoing light beam is deflected to both sides, thereby widening the viewing angle in the shared state. For example, light with a viewing angle within ±30° can be diverged to an area outside ±30°, so that a good display effect can be obtained even at a large viewing angle on the side.

[0050] When the light is diffused by the difference in refractive index between the liquid crystal layer 23 and the dimming structure layer 212, the influence of the first electrode layer 213 on the light path can be temporarily ignored. The reason is that, on the one hand, the thickness of the first electrode layer 213 is relatively thin, usually only a thin film layer of tens of nanometers, and its thickness can be selected as about 50nm, for example, while the thickness of the dimming structure layer 212 can be selected as several microns, and the difference between the two is relatively large. As a result, the thin film layer can be arranged in a conformal manner with the surface of the dimming structure layer 212 facing the first electrode layer 213, and has little influence on the light path. On the other hand, the first electrode layer 213 is usually made of a transparent metal oxide conductor material, and its refractive index is usually close to that of the dimming structure layer 212, for example, it can be selected as about 1.5, thereby further reducing the influence of refraction on the collimated light.

[0051] On this basis, taking the case where the surface of the dimming structure layer 212 facing the first electrode layer 213 is an arc surface, the collimated light incident from below has an angle with the normal at the incident point of the arc surface, and refraction occurs at this point. Further taking the case where the refractive index of the liquid crystal layer 23 is greater than the refractive index of the dimming structure layer 212 as an example, according to the calculation formula of light refraction n1sinθ1=n2sinθ2, it can be known that the refractive index n2 of the liquid crystal layer 23 is greater than the refractive index n1 of the dimming structure layer 212, then the angle θ2 between the propagation path of the light in the liquid crystal layer 23 and the normal is smaller than the angle θ1 between the propagation path of the light in the dimming structure layer 212 and the normal, that is, the propagation direction of the light changes from being parallel to the thickness direction Z of the display panel 100 to being inclined in the direction close to the normal, thereby widening the light emitting area and increasing the brightness at a large viewing angle in the shared state.

[0052] Correspondingly, in the anti-peeping state, an electric field is applied and the refractive index of the liquid crystal layer 23 is adjusted to make it the same or close to the refractive index of the dimming structure layer 212. For example, it can have a difference less than or equal to 0.1. At this time, the collimated light does not refract or refracts with a small deviation at the interface between the dimming structure layer 212 and the first electrode layer 213, thereby reducing the possibility of light diverging outward and realizing the corresponding anti-peeping function.

[0053] The display panel 100 in the embodiment of the present application is provided with an anti-peeping component 20, wherein the refractive index of the liquid crystal layer 23 therebetween can be changed through the substrate components on both sides, thereby conveniently switching between the anti-peeping state and the shared state. At the same time, in the shared state, the brightness at a large viewing angle can be improved, and the display effect can be improved. Furthermore, by arranging the first electrode layer 213 on the side of the dimming structure layer 212 facing the second electrode layer 222, the influence of the dimming structure layer 212 on the electric field strength can be reduced, thereby reducing the voltage required to drive the liquid crystal molecules to deflect, and reducing the power consumption of the display panel 100.

[0054] Please also read Figures 4 to 6 , Figure 4 is a schematic diagram of the structure of the second electrode layer provided by an embodiment of the present application, Figure 5 is a schematic structural diagram of a first electrode layer provided in one embodiment of the present application, Figure 6 It is a schematic diagram of the structure of the second electrode layer provided in another embodiment of the present application.

[0055] In some optional embodiments, at least one of the first electrode layer 213 and the second electrode layer 222 is provided with a plurality of hollow portions 214 penetrating along the thickness direction Z of the display panel 100 , and the plurality of hollow portions 214 are arranged at intervals.

[0056] In the anti-peeping component 20, the first electrode layer 213 and the second electrode layer 222 are arranged opposite to each other and are used to form an electric field. On this basis, at least one of the first electrode layer 213 and the second electrode layer 222 can be provided with a hollow portion 214 to achieve its own patterning and form an inclined electric field between the first electrode layer 213 and the second electrode layer 222.

[0057] Specifically, taking the second electrode layer 222 provided with a hollow portion 214 as an example, the hollow portion 214 may be in a circular hole shape, a square hole shape, a strip shape or an irregular shape, etc., and a plurality of hollow portions 214 are arranged at intervals from each other, and may be evenly distributed on the second electrode layer 222. The hollow portion 214 is arranged to penetrate the second electrode layer 222 along the thickness direction Z, and the hollow portion 214 may be a hole-shaped structure formed by being surrounded by the electrode layer, or the hollow portion 214 may divide the electrode layer into a plurality of sub-electrodes.

[0058] Optionally, after the liquid crystal molecules in the liquid crystal layer 23 are aligned, each liquid crystal molecule may have a certain pre-tilt angle, including a positive pre-tilt angle and a negative pre-tilt angle. On this basis, if the first electrode layer 213 and the second electrode layer 222 are both surface electrodes arranged on the front side and are completely facing each other, the electric field formed is usually a vertical electric field with a direction perpendicular to the electrode layer. Under the action of the vertical electric field, liquid crystal molecules with different pre-tilt angles are prone to partial positive warping and partial negative warping. The arrangement disorder problem, which leads to the appearance of "snowflakes" and other poor display phenomena. By providing a hollow portion 214 in at least one of the first electrode layer 213 and the second electrode layer 222, a tilted electric field can be formed between the two electrode layers through hollowing, thereby improving the display effect.

[0059] In some optional embodiments, the plurality of hollow portions 214 extend along the first direction X and are arranged at intervals along the second direction Y, and the first direction X intersects the second direction Y; or, the plurality of hollow portions 214 are arranged in an array.

[0060] In the embodiment where the hollow portions 214 are provided, in order to make the distribution of the hollow portions 214 more uniform, the multiple hollow portions 214 can be extended parallel to each other along the first direction X, and arranged at intervals in the second direction Y, and can further be arranged at equal intervals, and the first direction X and the second direction Y intersect and can be mutually perpendicular. The extension dimension of the hollow portion 214 in the first direction X can be the same or similar to the extension dimension of the substrate assembly on which it is provided, so that the electrode layer forms a plurality of strip-shaped sub-electrodes. Alternatively, the hollow portion 214 can have a shorter extension dimension in the first direction X, and the multiple hollow portions 214 can be arranged at intervals in the first direction X.

[0061] It is understood that, in the display panel 100, the dimming structure layer 212 may include a plurality of circular microlens units, or the dimming structure layer 212 may include a plurality of cylindrical lenses / prism structures extending in a certain direction. In the embodiment where the dimming structure layer 212 includes a cylindrical lens / prism structure and at least one of the two electrode layers is provided with a hollow portion 214, each cylindrical structure may extend along the first direction X or the second direction Y correspondingly.

[0062] Optionally, the hollow portion 214 may also be a plurality of hole-like structures arranged in an array, which may be square holes, round holes, polygonal holes, etc. This application does not make any specific limitation, as long as it is easy to process.

[0063] By providing the hollow portions 214 in the shape of strips or holes arranged in an array, the electrode layer can be easily processed while being evenly distributed.

[0064] In some optional embodiments, the hollow portion 214 includes a first hollow portion 2141 and a second hollow portion 2142 respectively arranged on the first electrode layer 213 and the second electrode layer 222, and along the thickness direction Z, the orthographic projection of the first hollow portion 2141 and the orthographic projection of the second hollow portion 2142 are at least partially staggered with each other.

[0065] In the embodiment of the present application, the first electrode layer 213 and the second electrode layer 222 may be provided with a hollow portion 214 at the same time, that is, the hollow portion 214 may include a first hollow portion 2141 provided in the first electrode layer 213 and a second hollow portion 2142 provided in the second electrode layer 222 at the same time. The shapes and sizes of the two hollow portions 214 may be the same or different. Preferably, the first hollow portion 2141 and the second hollow portion 2142 have the same or similar shapes and sizes.

[0066] Furthermore, the first hollow portion 2141 and the second hollow portion 2142 can be staggered to minimize the area of ​​the region where the first electrode layer 213 and the second electrode layer 222 are directly opposite to each other and form a vertical electric field. At the same time, the first electrode layer 213 and the second electrode layer 222 are orthographically projected along the thickness direction Z of the display panel 100, and the orthographic projections of the first hollow portion 2141 and the second hollow portion 2142 can be at least partially staggered, and can further be completely staggered. By making the hollow portions 214 on both sides not completely opposite to each other, the possibility of too low electric field strength in a certain area and insufficient liquid crystal deflection can be reduced.

[0067] By providing the hollow portions 214 in both electrode layers and making the two hollow portions 214 at least partially non-opposite to each other, the display effect of the display panel 100 can be further improved on the basis of forming an inclined electric field.

[0068] In some optional embodiments, the first hollow portion 2141 and the second hollow portion 2142 both extend along the first direction X and are arranged at intervals in the second direction Y. In the second direction Y, the extension dimension of the first hollow portion 2141 is the same as the extension dimension of the second hollow portion 2142, and the spacing between adjacent first hollow portions 2141 is the same as the spacing between adjacent second hollow portions 2142.

[0069] In the embodiment where the first electrode layer 213 and the second electrode layer 222 are respectively provided with the first hollow portion 2141 and the second hollow portion 2142 , the two hollow portions 214 may be selected to have the same shape structure.

[0070] Specifically, the first hollow portion 2141 and the second hollow portion 2142 can be selected to be strip structures that extend along the first direction X and are spaced apart in the second direction Y, and the dimensions of the two hollow portions 214 in the second direction Y, that is, the width, can be the same, and the interval between adjacent first hollow portions 2141 and the interval between adjacent second hollow portions 2142 can be the same, so that the first electrode layer 213 and the second electrode layer 222 are easy to process, and at the same time, it is easy to adjust the area of ​​the region where the two hollow portions 214 are set opposite each other.

[0071] Exemplarily, in an embodiment where the dimming structure layer 212 includes a cylindrical lens / prism structure and both electrode layers are provided with a hollow portion 214, the first hollow portion 2141 and the second hollow portion 2142 can have the same or similar shapes and sizes, and the misalignment size of the first hollow portion 2141 and the second hollow portion 2142 on both sides of the liquid crystal layer 23 can be the same or similar to the spacing between adjacent cylindrical lenses / prisms, for example, it can be greater than 0 and less than 2μm.

[0072] In some optional embodiments, the angle between at least a portion of the surface of the dimming structure layer 212 facing the first electrode layer 213 and the thickness direction Z of the display panel 100 is less than 90°; the dimming structure layer 212 includes a plurality of dimming microstructures 2121, and the surface of the dimming microstructure 2121 facing the liquid crystal layer 23 is an arc-shaped surface, or the surface of the dimming microstructure 2121 facing the liquid crystal layer 23 is a plane, and the angle between the extension direction of the plane and the thickness direction Z is greater than 0° and less than 90°.

[0073] The dimming structure layer 212 in the anti-peeping component 20 is used to cause the collimated light to be refracted at its interface or at the boundary of the liquid crystal layer 23 toward the dimming microstructure 2121. As a result, the side surface of the dimming structure layer 212 facing the liquid crystal layer 23 can have an angle less than 90° with the thickness direction Z, so that there is a certain angle between the collimated light and the normal of the side surface, thereby causing the collimated light to be refracted.

[0074] Specifically, the dimming structure layer 212 may include a plurality of dimming microstructures 2121, which may be lenses so that the surface facing the liquid crystal layer 23 is a curved surface, or the dimming microstructures 2121 may be prisms with a triangular or polygonal cross-section so that the surface facing the liquid crystal layer 23 is a slope.

[0075] Further, in the embodiment where the aforementioned surface is a curved surface and the dimming microstructure 2121 is a lens unit, the dimming microstructure 2121 may be a plano-convex lens or a Fresnel lens convex toward the direction of the liquid crystal layer 23. Alternatively, in the embodiment where the aforementioned surface is a curved surface and the dimming microstructure 2121 is a cylindrical lens, the dimming microstructure 2121 may be a cylindrical plano-convex lens.

[0076] By providing a plurality of dimming microstructures 2121 , the scattering effect of the dimming structure layer 212 on collimated light can be easily adjusted, and the dimming structure layer 212 can be easily processed.

[0077] Please also read Figure 7 and Figure 8 , Figure 7 is a structural diagram of an anti-peeping component provided by another embodiment of the present application, Figure 8 It is a structural schematic diagram of a dimming structure layer provided in one embodiment of the present application.

[0078] In some optional embodiments, the plurality of dimming microstructures 2121 extend along a third direction P and are arranged at intervals along a fourth direction Q, the third direction P intersects with the fourth direction Q, and in a cross-section perpendicular to the third direction P, the cross-sectional shape formed by the dimming microstructure 2121 is a semicircle, a semi-ellipse or an isosceles triangle.

[0079] Optionally, the dimming microstructure 2121 may have a longer extension dimension in its own extension direction, specifically, it may extend along the third direction P and be arranged at intervals in the fourth direction Q, the third and fourth directions Q intersect, and may further be mutually perpendicular. It is understood that, in this embodiment, by taking a cross-sectional graph of the dimming microstructure 2121 through a cross section perpendicular to the third direction P, the structural surface graphs at various locations in the same dimming microstructure 2121 may be selected to be the same or different.

[0080] In the embodiment where the first electrode layer 213 and / or the second electrode layer 222 is provided with a hollow portion 214 and the hollow portion 214 extends along the first direction X, the first direction X and the third direction P may be parallel or perpendicular to each other.

[0081] Exemplarily, the cross-sectional shape of the dimming microstructure 2121 may be an isosceles triangle, and the base of the isosceles triangle is arranged toward the first substrate 211, so that the dimming microstructure 2121 is in the form of a cylindrical prism as a whole. Alternatively, the cross-sectional shape of the dimming microstructure 2121 may be semicircular or semi-elliptical and have the same area and shape everywhere, so that the dimming microstructure 2121 is in the form of a convex lens structure of a semi-cylinder or a semi-elliptical column as a whole. Alternatively, the cross-sectional shape of the dimming microstructure 2121 may be semicircular or semi-elliptical and have different shapes and sizes everywhere, so that the dimming microstructure 2121 includes a plurality of sub-lens structures arranged in sequence along the third direction P, and the orthographic projection of each sub-lens structure in the thickness direction Z may be circular.

[0082] By configuring the dimming microstructure 2121 to have a semicircular or semi-elliptical cross section, the dimming microstructure 2121 can have a good scattering effect. By configuring the dimming microstructure 2121 to have a triangular cross section, the dimming microstructure 2121 can be easily processed.

[0083] In some optional embodiments, in the fourth direction Q, the extended dimension of the dimming microstructure 2121 is 4 μm to 16 μm, the spacing between adjacent dimming microstructures 2121 is 0 to 2 μm, and in the thickness direction Z, the extended dimension of the dimming microstructure 2121 is 2 μm to 8 μm.

[0084] Optionally, in an embodiment where the dimming microstructures 2121 extend along the third direction P and are arranged in the fourth direction Q, the width of each dimming microstructure 2121 along the fourth direction Q may be 4 μm to 16 μm, and the thickness along the thickness direction Z may be 2 μm to 8 μm, so that each dimming microstructure 2121 has a suitable volume. At the same time, the spacing between adjacent dimming microstructures 2121 may be 0 to 2 μm, so as to save processing costs while improving the scattering effect of collimated light and further improving the display effect.

[0085] Furthermore, the dimming microstructure 2121 is orthographically projected along the thickness direction Z, and the orthographic projection formed at the position where the dimming microstructure 2121 has the largest thickness is recorded as the highest line. Then, the interval between the highest lines of two adjacent dimming microstructures 2121 may be 8 μm to 12 μm.

[0086] In some optional embodiments, the refractive index of the dimming structure layer 212 is 1.5-1.6, and the refractive index of the liquid crystal layer 23 is 1.5-1.9.

[0087] In the anti-peeping component 20, the refractive index of the dimming structure layer 212 can be adjusted by adjusting the manufacturing material thereof, and its specific refractive index can be selected to be between 1.5 and 1.6, so as to adjust the refractive index of the liquid crystal layer 23 to match the refractive index of the dimming structure layer 212. Accordingly, the refractive index of the liquid crystal layer 23 can be selected to be between 1.5 and 1.9, and can be adjusted within this range according to the influence of the electric field.

[0088] Optionally, the liquid crystal layer 23 may have an e-light refractive index n e and the refractive index of o light n o , where n e Can be 1.7~1.9, n o It can be 1.5 to 1.7.

[0089] By limiting the refractive index of the dimming structure layer 212 and the refractive index of the liquid crystal layer 23 , it is possible to match the refractive indexes of the two so that the anti-peeping component 20 can be switched between the anti-peeping state and the sharing state by applying an electric field to the liquid crystal layer 23 .

[0090] In some optional embodiments, the dimming structure layer 212 is provided with a plurality of dimming microstructures 2121 and one or more supporting portions 2122, and in the thickness direction Z of the display panel 100, the extension dimension of the supporting portion 2122 is greater than or equal to the extension dimension of the dimming microstructure 2121; the display panel 100 also includes a supporting member 24, and the supporting member 24 is arranged in the liquid crystal layer 23, and in the thickness direction Z, the two ends of the supporting member 24 are respectively abutted against the first electrode layer 213 and the second electrode layer 222, and the orthographic projection of the supporting member 24 is located within the contour range of the orthographic projection of the supporting portion 2122.

[0091] In order to maintain an appropriate distance between the first substrate assembly 21 and the second substrate assembly 22, a support portion 2122 may also be provided in the dimming structure layer 212. The support portion 2122 is used to support the support member 24. The opposite side ends of the support member 24 in the thickness direction Z may respectively abut against the second substrate assembly 22 and the support portion 2122 in the dimming structure layer 212.

[0092] Specifically, the dimming structure layer 212 may include a plurality of dimming microstructures 2121 and one or more supporting portions 2122. The projection of the supporting portion 2122 along the thickness direction Z may be rectangular, circular, elliptical or polygonal, etc. The size of the supporting portion 2122 in the thickness direction Z may be greater than or equal to the size of the dimming microstructure 2121. It may be further selected that the thickness of the supporting portion 2122 is flush with the maximum thickness of the dimming microstructure 2121 to facilitate processing and abutment with the support member 24.

[0093] The support member 24 is used to form a support in the thickness direction Z between the first electrode assembly and the second electrode assembly, and its size in the thickness direction Z can be set according to the required size of the liquid crystal layer 23. The support member 24 is arranged on the support portion 2122, and along the thickness direction Z, the orthographic projection of the support portion 2122 covers the orthographic projection of the support member 24. By providing the support portion 2122 and making the support member 24 abut against it, the stability of the support can be improved, and the possibility of the dimming structure layer 212 being compressed and broken can be reduced.

[0094] In some optional embodiments, the plurality of dimming microstructures 2121 extend along a third direction P and are arranged at intervals along a fourth direction Q, and the third direction P intersects with the fourth direction Q; in the thickness direction Z, the orthographic projection of each of the supporting portions 2122 is connected to the orthographic projections of the plurality of dimming microstructures 2121, and the orthographic projection area of ​​the supporting portion 2122 is greater than the orthographic projection area of ​​the supporting member 24.

[0095] In an embodiment where the dimming structure layer 212 includes multiple dimming microstructures 2121 and each dimming microstructure 2121 extends along the third direction P and is arranged along the fourth direction Q, the support portion 2122 can have a certain extension dimension in both the third direction P and the fourth direction Q, so that the same support portion 2122 can be connected to multiple dimming microstructures 2121 at the same time.

[0096] Specifically, the support portion 2122, the support member 24 and the dimming microstructure 2121 are all projected along the thickness direction Z, and the orthographic projection area of ​​the support portion 2122 is larger than the orthographic projection area of ​​the support member 24. The orthographic projection of the support portion 2122 is connected to the orthographic projections of the multiple dimming microstructures 2121 and covers the orthographic projection of the support member 24.

[0097] By configuring the support portion 2122 to have a larger area, the alignment requirement between the support member 24 and the support portion 2122 can be reduced, thereby reducing the processing difficulty of the display panel 100 and improving the reliability.

[0098] See also Fig. 9 , Fig. 9 It is a schematic diagram of the structure of a display panel provided in another embodiment of the present application.

[0099] In some optional embodiments, the display panel 100 also includes a backlight assembly 30, the anti-peeping assembly 20 is arranged between the display assembly 10 and the backlight assembly 30, the display assembly 10 includes a first polarizer 11 and a second polarizer 12, the second polarizer 12 is arranged between the first polarizer 11 and the anti-peeping assembly 20, and a third polarizer 25 is arranged on the side of the anti-peeping assembly 20 facing the backlight assembly 30; wherein the polarization axis of the first polarizer 11 intersects with the polarization axis of the second polarizer 12, and the polarization axis of the second polarizer 12 is parallel to the polarization axis of the third polarizer 25.

[0100] The display panel 100 in the embodiment of the present application may be optionally a liquid crystal display panel 100, and is provided with a backlight assembly 30 for providing a light source. In this case, the anti-peeping assembly 20 may be arranged between the backlight assembly 30 and the display assembly 10, so that the light emitted by the backlight assembly 30 is adjusted by the anti-peeping assembly 20 and then incident on the display assembly 10.

[0101] In this embodiment, in order to realize the control of the displayed image, the display component 10 may include a first polarizer 11 and a second polarizer 12, which may be arranged at intervals in the thickness direction Z, and a liquid crystal structure and electrodes for controlling the liquid crystal structure are sandwiched therebetween. The second polarizer 12 is arranged on the side of the first polarizer 11 close to the anti-peep component 20, and the polarization axis of the first polarizer 11 intersects with the polarization axis of the second polarizer 12, and may be further arranged to be perpendicular to each other, so as to realize the function of liquid crystal display.

[0102] Furthermore, a third polarizer 25 may be provided on the side of the anti-peeping component 20 facing the backlight component 30, and the polarization axis of the third polarizer 25 is parallel to the polarization axis of the second polarizer 12. Thus, light is emitted from the backlight component 30 toward the side of the anti-peeping component 20, and after passing through the third polarizer 25, it becomes polarized light with a polarization direction parallel to the polarization axis of the third polarizer 25. In the anti-peeping state, since the liquid crystal molecules are in a tilted and warped state, the polarization state of the collimated light passing through the liquid crystal layer 23 remains unchanged, that is, the original polarization direction is maintained, and it can pass through the second polarizer 12 smoothly; and the polarization state of the obliquely emitted light will change after passing through the liquid crystal layer 23, and will be absorbed at the second polarizer 12, further improving the anti-peeping effect.

[0103] By disposing a third polarizer 25 whose polarization axis is parallel to the second polarizer 12 on the side of the anti-peeping component 20 facing the backlight component 30, the light passing through the anti-peeping component 20 can be further screened so that the inclined light is absorbed and the collimated light is emitted normally, thereby further improving the anti-peeping effect.

[0104] In some optional embodiments, the first substrate assembly 21 is disposed between the second substrate assembly 22 and the backlight assembly 30 .

[0105] In the anti-peeping assembly 20, the first substrate assembly 21 and the second substrate assembly 22 are arranged opposite to each other, and the first substrate assembly 21 is provided with a dimming structure layer 212. In the embodiment in which the backlight assembly 30 is provided, the first substrate assembly 21 can be provided on the side closer to the backlight assembly 30, so that the first substrate assembly 21 is provided below the liquid crystal layer 23. This facilitates the processing to form the dimming structure layer 212, and in the embodiment in which the support portion 2122 and the support member 24 are provided, it is convenient to align the support member 24 with the support portion 2122.

[0106] In some optional embodiments, the display panel 100 also includes an anti-peep film, which is sandwiched between the anti-peep component 20 and the backlight component 30; the anti-peep film includes a plurality of micro-gap structures extending parallel to each other, and the dimming structure layer 212 includes a plurality of dimming microstructures 2121 extending parallel to each other, and the extension direction of the micro-gap structure is parallel to the extension direction of the dimming microstructure 2121.

[0107] The display panel 100 in the embodiment of the present application may further include an anti-peeping film, which is disposed on the side of the anti-peeping component 20 facing the backlight component 30 and may be provided with a plurality of mutually parallel micro-slit structures, so that the light can be further corrected in the direction of the emitted light when it is emitted through the micro-slit structures, thereby further improving the anti-peeping effect. Along the thickness direction Z, the orthographic projection of the anti-peeping film can cover the orthographic projection of the area used for display in the display component 10.

[0108] In an embodiment where the dimming structure layer 212 includes a plurality of dimming microstructures 2121 extending along the third direction P and arranged along the fourth direction Q, these micro-slit structures may optionally also extend along the third direction P so that the diffusion and convergence directions of the light correspond to each other.

[0109] See also Fig.10 , Fig.10 This is a schematic diagram of the structure of a display panel provided in yet another embodiment of the present application.

[0110] In some optional embodiments, the display panel 100 also includes a backlight assembly 30, the anti-peeping assembly 20 is arranged on the side of the display assembly 10 away from the backlight assembly 30, the display assembly 10 includes a first polarizer 11 and a second polarizer 12, and the second polarizer 12 is arranged on the side of the first polarizer 11 away from the anti-peeping assembly 20; in the shared state, the arrangement direction of the liquid crystal molecules in the liquid crystal layer 23 is perpendicular to the polarization axis of the first polarizer 11 and parallel to the polarization axis of the second polarizer 12.

[0111] Different from the above-mentioned embodiment in which the anti-peeping component 20 is disposed between the backlight component 30 and the display component 10, the backlight component 30 in the display panel 100 can also be disposed on the side of the display component 10 away from the backlight component 30. In this embodiment, the display component 10 can be provided with a first polarizer 11 and a second polarizer 12 similar to the above-mentioned embodiment to realize the corresponding liquid crystal display function.

[0112] In this embodiment, the alignment of the liquid crystal molecules in the liquid crystal layer 23 can be adjusted so that they are in a posture perpendicular to the first polarizer 11 in the shared state. As a result, the display panel 100 in this embodiment can widen the viewing angle and improve the brightness at a large viewing angle by refraction of collimated light at the dimming structure layer 212 in the shared state. At this time, the liquid crystal molecules are in a "lying" state perpendicular to the polarization axis of the first polarizer 11 and parallel to the polarization axis of the second polarizer 12. The incident light is parallel to the short axis of the liquid crystal molecules. It can be regarded that the liquid crystal layer 23 has only one refractive index, and no birefringence occurs at the liquid crystal layer 23, so the light can be emitted normally.

[0113] In contrast, in the anti-peeping state, collimated light passes through the dimming structure layer 212 and can be considered as not refracted. However, since the direction of the inclined light is neither parallel nor perpendicular to the long axis of the liquid crystal molecules, birefringence will occur, causing ghosting at a large viewing angle from the side, thereby blurring the displayed image seen from the side, thereby achieving the anti-peeping function.

[0114] Please also read Fig.11 and Fig.12 , Fig.11 is a schematic diagram of the structure of a display panel provided by another embodiment of the present application, Fig.12 It is a structural schematic diagram of a display panel provided in yet another embodiment of the present application.

[0115] In some optional embodiments, the display panel 100 further includes a control component 40 , the control component 40 includes a display chip 41 and an anti-peeping chip 42 , the display chip 41 is electrically connected to the display component 10 , and the anti-peeping chip 42 is electrically connected to the anti-peeping component 20 .

[0116] In order to achieve control of the display component 10 and the anti-peeping component 20, the display panel 100 can also include a control component 40, which further includes a display chip 41 for controlling the display component 10 and an anti-peeping chip 42 for controlling the anti-peeping component 20. The two can be optionally set independently of each other and electrically connected through a flexible circuit board.

[0117] Specifically, the display chip 41 can be directly bound and set on the substrate of the display component 10 and electrically connected to the display component 10 to control the display of the image in the display component 10. The anti-peeping chip 42 can be set on the flexible circuit board and electrically connected to the anti-peeping component 20 to apply electrical signals to the first electrode layer 213 and the second electrode layer 222.

[0118] By providing the control component 40 , the display component 10 and the anti-peeping component 20 can be controlled separately, thereby improving signal accuracy and control reliability.

[0119] In some optional embodiments, the display panel 100 also includes a power supply, and the anti-peeping chip 42 is used to control the power supply to provide a constant electric signal to one of the first electrode layer 213 and the second electrode layer 222, and to provide a first electric signal to the other, so that the display panel 100 switches to an anti-peeping state; the anti-peeping chip 42 is also used to control the power supply to provide a constant electric signal to one of the first electrode layer 213 and the second electrode layer 222, and to provide a second electric signal to the other, so that the display panel 100 switches to a shared state; the liquid crystal layer 23 includes positive liquid crystal, and the voltage difference of the first electric signal is greater than the voltage difference of the second electric signal.

[0120] The display panel 100 may further include a power supply, which may be a lithium battery, for supplying power to the display component 10 and the anti-peeping component 20. Under the control of the anti-peeping chip 42, the power supply provides a constant electric signal to one of the first electrode layer 213 and the second electrode layer 222, and the other provides a first electric signal or a second electric signal, so as to form an electric field through the difference between the constant electric signal and the first / second electric signal, wherein the first / second electric signal can be set according to the required electric field strength.

[0121] Furthermore, positive liquid crystal is preferably used in the liquid crystal layer 23. The voltage required for the positive liquid crystal to switch to the shared state is lower than the voltage required to switch to the anti-peeping state, and the voltages required in the anti-peeping state and the shared state are relatively small, which can reduce the power consumption of the anti-peeping component 20 and the display panel 100.

[0122] For example, if the liquid crystal layer 23 uses positive liquid crystal, the voltage difference between the shared state and the anti-peeping state and the reference voltage is 1V and 3V respectively; if the liquid crystal layer 23 uses negative liquid crystal, the voltage difference between the shared state and the anti-peeping state and the reference voltage is 5V and 2V respectively. Therefore, the use of positive liquid crystal can effectively reduce the power consumption of the display panel 100.

For details, please refer to the specific description of the display panel 100 in the above embodiments, and this embodiment will not be repeated here.
