[0031] The present application is described in detail below with reference to the accompanying drawings and optional embodiments. It should be noted that, under the premise of no conflict, the embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0032] like Figure 1 As shown, as a first embodiment of the present application, a display panel 100 is disclosed, wherein the display panel 100 includes a first substrate 110 and a second substrate 120 arranged opposite to each other, and an anti-peeping layer 130 arranged between the first substrate 110 and the second substrate 120, and the display panel 100 also includes a plurality of anti-peeping components 200, wherein the plurality of anti-peeping components 200 are arranged in the anti-peeping layer 130, and each of the anti-peeping components 200 includes a hollow shell 210 and an anti-peeping body 220 arranged in the hollow shell 210, The hollow shell 210 is provided with a plurality of driving electrodes 211, and the anti-peeping body 220 is provided with a mirror coating 221 and a charged part 222, and the charged part 222 is spaced apart from the mirror coating 221. The plurality of driving electrodes 211 are energized to drive the charged part 222 to rotate the anti-peeping body 220, so as to control the rotation of the mirror coating 221, thereby realizing the anti-peeping display and normal display of the display panel 100; wherein, the anti-peeping body 220 is opaque and non-reflective, and is made of a black light-absorbing material.

[0033] The display panel 100 of this embodiment controls whether the driving electrode 211 in the hollow housing 210 is energized. After the driving electrode 211 is energized, the electric field generated by the driving electrode 211 attracts the charged portion 222 to rotate the anti-peeping body 220, so as to control the position of the mirror coating 221 on the anti-peeping body 220, thereby controlling the direction in which the light incident from the outside into the display panel 100 is reflected by the mirror coating 221. When the display panel 100 is an anti-peeping display, the mirror coating 221 can reflect the light to the side viewing angle of the user, and the people around the user cannot fully view the display content of the display panel 100; when When the display panel 100 is in normal display, the mirror coating 221 is controlled to rotate so that external light is irradiated onto the anti-peeping body 220, so that the light cannot be reflected. People around the user can view the display content of the display panel 100, and the user can switch the display mode of the display panel 100 to anti-peeping display or normal display according to actual usage needs; it should be noted that the user's side viewing angle generally refers to the viewing angle of people around the user, such as the left side, right side and other directions of the user. After the anti-peeping body 220 is rotated to a specific position, the mirror coating 221 reflects the light from the outside that is incident on the display panel 100 to that direction.

[0034] like Figure 2 and Figure 3As shown, as the second embodiment of the present application, which is a further improvement of the first embodiment of the present application, a display panel 100 is disclosed, wherein the anti-peeping layer 130 includes a driving circuit layer 131, a pixel definition layer 132 and a light-emitting component 133, wherein the driving circuit layer 131 is arranged on the first substrate 110, and the pixel definition layer 132 and the light-emitting component 133 are arranged on the driving circuit layer 131, and the pixel definition layer 132 divides a plurality of sub-pixel areas 140, wherein the sub-pixel area 140 includes a first sub-pixel area 141 and a second sub-pixel area 142, and the first sub-pixel area 141 and the second sub-pixel area 142 are arranged at intervals, and the anti-peeping component 200 is arranged in the first sub-pixel area 141, and the light-emitting component 133 is arranged in the second sub-pixel area 142, and the light-emitting component 133 includes an anode layer 134, a light-emitting layer 134 arranged in sequence, and a 135 and a cathode layer 136, the anode layer 134 is arranged on the driving circuit layer 131, the light-emitting layer 135 is arranged on the anode layer 134, the cathode layer 136 is arranged on the light-emitting layer 135, a first encapsulation layer 150 is arranged in the first sub-pixel area 141, and the first encapsulation layer 150 is provided with a groove for installing the anti-peeping component 200, and the anti-peeping component 200 is arranged in the groove, the anti-peeping layer 130 also includes a second encapsulation layer 151, the second encapsulation layer 151 is arranged on the pixel definition layer 132, and covers the cathode layer 136, the pixel definition layer 132, the anti-peeping component 200 and the first encapsulation layer 150, and the second substrate 120 is arranged on the second encapsulation layer 151; in this embodiment, the area of ​​the first sub-pixel area 141 is smaller than the area of ​​the second sub-pixel area 142.

[0035] The anti-peeping component 200 is disposed in the first sub-pixel region 141, and the light-emitting component 133 is disposed in the second sub-pixel region 142, and the area of ​​the first sub-pixel region 141 is smaller than the area of ​​the second sub-pixel region 142. The aperture ratio of the display panel 100 is related to the area of ​​the first sub-pixel region 141. The smaller the area of ​​the first sub-pixel region 141, the larger the aperture ratio of the display panel 100. Conversely, in this embodiment, the aperture ratio of the display panel 100 is increased by reducing the area of ​​the first sub-pixel region 141 as much as possible.

[0036] A first encapsulation layer 150 is provided on the first sub-pixel area 141, and a groove for installing the peep-proof component 200 is provided on the first encapsulation layer 150. The peep-proof component 200 is arranged in the groove to be installed in the first sub-pixel area 141, so that the upper and lower sides of the display panel 100 of this embodiment can be better made of the bonding film layer, which is convenient for the production of the display panel 100; wherein, the first encapsulation layer 150 is provided with a via hole, and the driving electrode 211 on the hollow shell 210 of the peep-proof component 200 is connected to the driving circuit layer 131 through the via hole, so that the hollow shell 210 of the peep-proof component 200 can be driven by the driving circuit layer 131. The driving electrode 211 is controlled to be on and off, thereby driving the anti-peeping body 220 to rotate, and the driving circuit layer 131 can be connected to a control IC dedicated to controlling the driving electrode 211; in this embodiment, the second sub-pixel area 142 is a normal display pixel, and the first sub-pixel area 141 is an area between two normal display pixels; wherein, in order to enable the mirror coating 221 on the anti-peeping body 220 to reflect light, the first encapsulation layer 150, the second encapsulation layer 151, the hollow shell 210, and the driving electrode 211 are all transparent, and the driving electrode 211 can be transparent ITO;

[0037] Furthermore, in this embodiment, the cross section of the hollow shell 210 is circular, the plurality of driving electrodes 211 are arranged in a circular array in the hollow shell 210, and the plurality of driving electrodes 211 are symmetrically arranged along the central axis of the hollow shell 210, such as Figure 3 As shown, the charged portion 222 of the peeping body 220 is positively charged, the number of the driving electrodes 211 is set to an even number, and the driving electrodes 211 are arranged opposite to each other in pairs; when it is necessary to drive the peeping body 220 to rotate to adjust the position of the mirror coating 221, the two opposite driving electrodes 211 are energized at the same time, one driving electrode 211 is positively charged, and the other driving electrode 211 is negatively charged. The positively charged driving electrode 211 and the negatively charged driving electrode 211 form an electric field, which attracts the charged portion 222 of the peeping body 220 to rotate toward the negatively charged driving electrode 211, and finally the positively charged charged portion 222 will stay at the negatively charged driving electrode 211, thereby driving the peeping body 220 to rotate, as shown in FIG. Figure 4As shown, the anti-peeping body 220 rotates to adjust the position of the mirror coating 221, so that the display panel 100 can be switched between anti-peeping display and normal display; in general, this embodiment can drive the anti-peeping ball set in the hollow shell 210 to rotate by controlling the on and off of the driving electrode 211, so as to adjust the position of the mirror coating 221 to achieve the switching of the display panel 100 between anti-peeping display and normal display; it should be noted that the charged part 222 of the anti-peeping body 220 can also be a negative charge. When the two opposite driving electrodes 211 are energized, the charged part 222 of the anti-peeping body 220 will be attracted to rotate toward the positively charged driving electrode 211.

[0038] In this embodiment, the anti-peeping body 220 can have two structural settings, namely a spherical structure and a cylindrical structure, which will be described below respectively:

[0039] like Figure 6 As shown, the anti-peeping body 220 is a spherical structure, and the hollow shell 210 is also a corresponding spherical structure. In one of the first sub-pixel areas 141, at least one anti-peeping component 200 is provided, and the anti-peeping components 200 are evenly distributed in the first sub-pixel area 141. The anti-peeping component 200 can achieve anti-peeping in any direction. For example, taking the light-emitting surface of the display panel 100 as the front side as an example, it can achieve anti-peeping in four directions of the left side, the right side, the upper side and the lower side, or even the upper left, the lower left, the upper right and the lower right. It only needs to set a corresponding driving electrode 211 at the corresponding position of the hollow shell 210 to drive the anti-peeping body 220 to rotate to a specific position, and the anti-peeping angle range is wide; and a plurality of anti-peeping components 200 can be provided, and a plurality of anti-peeping components 200 can be arranged, for example, arranged along the extension direction of the data line of the display panel 100, so that each first sub-pixel area 141 of the display panel 100 can reflect a certain amount of light, thereby achieving a better anti-peeping effect;

[0040] like Figure 7 As shown, the anti-peeping body 220 is a cylindrical structure, and the hollow shell 210 is also a corresponding cylindrical structure. In one of the first sub-pixel areas 141, the anti-peeping component 200 is provided with a and is arranged parallel to the extension direction of the data line of the display panel 100. In this embodiment, the extension direction of the data line parallel to the display panel 100 is as follows Figure 7In the Y-axis direction shown, taking the light-emitting surface of the display panel 100 as the front side as an example, anti-peeping in both the left and right directions can be achieved. It is only necessary to set the corresponding driving electrode 211 at the corresponding position of the hollow shell 210 to drive the anti-peeping body 220 to rotate to a specific position. The anti-peeping body 220 is a cylindrical structure, so that only one anti-peeping component 200 is required to be set in a first sub-pixel area 141 to reflect a certain amount of light and achieve a better anti-peeping effect. Compared with the above-mentioned spherical anti-peeping body 220, the steps of installing the anti-peeping component 200 are simpler.

[0041] Further, in this embodiment, the mirror coating 221 may be provided at multiple locations, or only at one location. When the mirror coating 221 is provided at only one location, if it is desired to simultaneously achieve left and right side peep-proofing, the anti-peep body 220 needs to be controlled by the driving electrode 211 to rotate at a high frequency, so that the mirror coating 221 of the anti-peep body 220 switches back and forth between the left and right sides. For example, the mirror coating 221 is controlled to face the left side at 1 / 60 second. Figure 3 As shown in (a), at 2 / 60 seconds, the mirror coating 221 is controlled to face the right side, as shown in FIG. Figure 3 As shown in (b), the cycle is repeated in this way, thereby realizing simultaneous peeping protection on both sides; the mirror coating 221 may also be provided at two locations, the two mirror coatings 221 are arranged adjacent to each other, and are symmetrically arranged along the charged portion 222. When the display panel 100 needs to be peeping-proof, the peeping protection body 220 is controlled by driving the electrode 211 to rotate the charged portion 222 to the side close to the first substrate 110, so that the two mirror coatings 221 can respectively reflect the light incident from the outside into the display panel 100 to the left and right sides, thereby realizing simultaneous peeping protection on both sides. Compared with setting only one mirror coating 221, it is not necessary to control the anti-peeping body 220 to rotate at high frequency to achieve multi-directional simultaneous anti-peeping, and the energy consumption required for anti-peeping is lower; of course, it can also be simultaneous anti-peeping in three directions or four directions. In this case, the anti-peeping body 220 is a spherical structure, and mirror coatings 221 corresponding to the number of anti-peeping directions are set, thereby achieving simultaneous anti-peeping in three sides, four sides or even multiple sides; designers can select and design the number of mirror coatings 221 on the anti-peeping body 220 according to actual needs, and there is no restriction here.

[0042] Furthermore, different colors of color resists or fluorescent powders may be disposed on the mirror coating 221 to realize different colors of emitted light, so that the reflected light forms a mixed color effect. Compared with the mirror coating 221 that only reflects white light, the light color is richer and the anti-peeping effect is better. Among them, the fluorescent powder can absorb ultraviolet or blue light and emit light autonomously to achieve the mixing of light to form mixed color light.

[0043] like Figure 5 As shown, the anti-peeping layer 130 includes a light shielding layer 137, and the light shielding layer 137 is provided at multiple locations, and the multiple light shielding layers 137 are respectively provided corresponding to the multiple anti-peeping components 200; wherein, in the direction from the first substrate 110 to the second substrate 120, the projection of the light shielding layer 137 covers the anti-peeping component 200, and the light shielding layer 137 is provided directly above the anti-peeping component 200. When the anti-peeping body 220 rotates, if the mirror coating 221 rotates to the side facing the second substrate 120, the light reflected by the mirror coating 221 will be reflected by the light shielding layer 13 7 is used to block the messy light from being emitted from the front viewing angle of the display panel 100. In general, the display panel 100 of this embodiment prevents the light from being reflected from the mirror coating 221 to the front viewing angle and affecting the user's viewing experience by disposing the light-shielding layer 137 just above the anti-peeping component 200. Of course, the light-shielding layer 137 may not be disposed on the anti-peeping layer 130, and a light-shielding layer 137 may be coated on one side of the hollow shell 210 close to the second substrate 120 to absorb the light at the front viewing angle emitted to the display panel 100 to prevent the visibility at the front viewing angle from being reduced.

[0044] Further, such as Figure 5 As shown, a filter layer 138 is also provided on the anti-peep layer 130. The filter layer 138 is arranged on the second packaging layer 151 and corresponds to the light-emitting component 133. The filter layer 138 is used to store the light of the light-emitting component 133 and also can reduce the reflection of the external ambient light. The filter layer 138 is a color resistance layer.

[0045] like Figure 3As shown, the hollow shell 210 is further provided with an insulating layer 212, and the insulating layer 212 is arranged to cover the driving electrode 211 to prevent the driving electrode 211 from directly contacting the charged part 222 of the anti-peeping body 220, resulting in electrical neutralization and inability to rotate, that is, the anti-peeping body 220 and the driving electrode 211 are arranged at an interval, wherein the insulating layer 212 is a transparent insulating layer 212, so that the light from the outside that enters the display panel 100 can pass through the insulating layer 212 and enter the mirror coating 221 of the anti-peeping body 220 to form a reflection; at the same time, in order to make the anti-peeping body 220 rotate better, a lubricating liquid 230 is provided between the insulating layer 212 and the anti-peeping body 220 The lubricating liquid 230 is an insulating lubricating liquid 230, and the density of the lubricating liquid 230 is greater than the density of the peeping body 220. The peeping body 220 is subjected to the buoyancy of the lubricating liquid 230 to overcome its own gravity, so that the peeping body 220 can be suspended in the hollow shell 210, thereby avoiding direct contact with the insulating layer 212 of the hollow shell 210, reducing the contact area and reducing friction, thereby making the rotation of the peeping body 220 easier; in this embodiment, the peeping body 220 can be a solid structure or a hollow structure. Compared with the peeping body 220 with a solid structure, the peeping body 220 with a hollow structure can reduce the weight of the peeping body 220, making the rotation of the peeping body 220 easier.

[0046] When manufacturing the peeping body 220 and the hollow shell 210, the peeping body 220 needs to be made of micron-level materials, and the mirror coating 221 and the charged part 222 are respectively plated on both sides of the peeping body 220. The charged part 222 is a charged layer. First, surface modification is performed on one side of the peeping body 220 to prepare the charged layer. After the preparation is completed, the charged layer is fixed under the action of an external electric field, and then the mirror coating 221 is plated to complete the manufacture of the peeping body 220. Among them, the mirror coating 221 and the charged part 222 can be opposite sides, or they can be not opposite sides, and they can be adjacent sides.
