[0069] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in combination with the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0070] Embodiment 1

[0071] Figure 1 FIG. 1 is a schematic diagram of a structure of a display panel according to an embodiment of the present invention. Figure 1As shown, the present embodiment provides a display panel, which includes a display substrate 10 and an anti-peeping component 20, the display substrate 10 has a plurality of light-emitting units 11, the anti-peeping component 20 is arranged on the light-emitting side of the display substrate 10, the anti-peeping component 20 has a first anti-peeping layer 21 and a second anti-peeping layer 22 which are arranged in sequence along a direction away from the display substrate 10, the first anti-peeping layer 21 has a plurality of first light-transmitting areas 211 which are arranged at intervals, the plurality of first light-transmitting areas 211 correspond one-to-one to the plurality of light-emitting units 11, and the orthographic projection of the first light-transmitting area 211 on the display substrate 10 covers the corresponding light-emitting units 11; the second anti-peeping layer 22 has a plurality of second light-transmitting areas 221 which are arranged at intervals, the plurality of second light-transmitting areas 221 correspond one-to-one to the plurality of light-emitting units 11, and the orthographic projection of the second light-transmitting area 221 on the display substrate 10 covers the corresponding light-emitting units 11.

[0072] In this field, a commonly used anti-peeping method is usually to set an anti-peeping component on the packaging layer. The anti-peeping component usually includes an anti-peeping layer. The color-changing area of ​​the anti-peeping layer is located at the bottom of the anti-peeping layer, and the thickness of the color-changing area is relatively thin. Part of the large-angle light is emitted, and the viewing angle is large, which leads to poor anti-peeping effect.

[0073] In response to the above problems, the present embodiment improves the structure of the anti-peeping component 20, which includes a first anti-peeping layer 21 and a second anti-peeping layer 22 stacked together, wherein the first anti-peeping layer 21 has a plurality of first light-transmitting areas 211 spaced apart, and the second anti-peeping layer 22 has a plurality of second light-transmitting areas 221 spaced apart, and the orthographic projections of the first light-transmitting areas 211 and the second light-transmitting areas 221 on the display substrate 10 cover the corresponding light-emitting units 11.

[0074] In this embodiment, the second privacy protection layer 22 is located on the side of the first privacy protection layer 21 away from the display substrate 10. Part of the light emitted by the light-emitting unit 11 is emitted through the first light-transmitting area 211, and part of the large-angle light emitted through the first light-transmitting area 211 is directly emitted to the non-light-transmitting area of ​​the second privacy protection layer 22. This part of the large-angle light is absorbed by the second privacy protection layer 22, reducing the emission of large-angle light, thereby reducing the user's viewing angle and improving the privacy protection effect. It can also be understood that since two privacy protection layers are provided in this embodiment, the total thickness of the privacy protection component is increased, thereby increasing the total thickness of the color-changing area, reducing the user's viewing angle and improving the privacy protection effect.

[0075] In addition, since the first anti-peep layer 21 transmits light only in the first light-transmitting area 211, and the second anti-peep layer 22 transmits light only in the second light-transmitting area 221, and blocks light at other positions, in order to further ensure the display effect of the display panel, the present invention corresponds multiple first light-transmitting areas 211 to multiple light-emitting units 11 one by one, and at the same time corresponds multiple second light-transmitting areas 221 to multiple light-emitting units 11 one by one, and the orthographic projection of each first light-transmitting area 211 on the display substrate 10 covers the corresponding light-emitting unit 11, and the orthographic projection of each second light-transmitting area 221 on the display substrate 10 covers the corresponding light-emitting unit 11. That is, the light emitted by each light-emitting unit 11 in a direction perpendicular to the display substrate 10 can pass through the first light-transmitting area 211 and the second light-transmitting area 221, so as to avoid the first anti-peep layer 21 and the second anti-peep layer 22 blocking the effective light, so as to improve the display effect of the display panel. During specific configuration, the size of the first light-transmitting area 211 and the second light-transmitting area 221 can be made greater than or equal to the size of the corresponding light-emitting unit, thereby ensuring that the orthographic projection of the first light-transmitting area 211 on the display substrate 10 covers the corresponding light-emitting unit 11, and the orthographic projection of each second light-transmitting area 221 on the display substrate 10 covers the corresponding light-emitting unit 11.

[0076] It should be noted that the orthographic projection of the first light-transmitting area 211 on the display substrate 10 covers the corresponding light-emitting unit 11, including two situations: one is that the orthographic projection of the first light-transmitting area 211 on the display substrate 10 covers and exceeds the corresponding light-emitting unit 11; the other is that the orthographic projection of the first light-transmitting area 211 on the display substrate 10 coincides with the corresponding light-emitting unit 11. The orthographic projection of the second light-transmitting area 221 on the display substrate 10 covers the corresponding light-emitting unit 11, including two situations: one is that the orthographic projection of the second light-transmitting area 221 on the display substrate 10 covers and exceeds the corresponding light-emitting unit 11; the other is that the orthographic projection of the second light-transmitting area 221 on the display substrate 10 coincides with the corresponding light-emitting unit 11.

[0077] Preferably, the orthographic projection of the first light-transmitting area 211 on the display substrate 10 covers and exceeds the corresponding light-emitting unit 11, and the orthographic projection of the second light-transmitting area 221 on the display substrate 10 covers and exceeds the corresponding light-emitting unit 11. In other words, the size of the first light-transmitting area 211 and the second light-transmitting area 221 is larger than the corresponding light-emitting unit 11, so as to ensure that the nearly vertical light emitted by the light-emitting unit 11 can pass through the first light-transmitting area 211 and the second light-transmitting area 221, so as to ensure the display effect of the display panel.

[0078] In addition, the anti-peeping component 20 in this embodiment may also include other anti-peeping layers in addition to the first anti-peeping layer 21 and the second anti-peeping layer 22. No specific limitation is made here. It is only necessary to ensure that the anti-peeping component 20 has at least two anti-peeping layers.

[0079] The display panel provided in this embodiment increases the total thickness of the color changing area of ​​the anti-peeping component by setting the first anti-peeping layer 21 and the second anti-peeping layer 22, thereby reducing the emission of some large-angle light, reducing the viewing angle, and improving the anti-peeping effect. In addition, the double-layer anti-peeping layer can improve the absorption of large-angle light, prevent large-angle light from being emitted from adjacent light-emitting units 11, and further reduce the risk of cross-color. In addition, since the first light-transmitting area 211 and the second light-transmitting area 221 both cover the corresponding light-emitting unit 11, it is ensured that the light emitted nearly vertically by the light-emitting unit 11 can pass through the first light-transmitting area 211 and the second light-transmitting area 221 to emit the display panel, so that users who look directly at the display panel can observe the displayed image, while users who look at the display panel from the side at a large angle cannot see the displayed image, thereby achieving the purpose of anti-peeping.

[0080] It should be noted that, with the direction perpendicular to the display panel as 0 degrees and the direction parallel to the display panel as 90 degrees, the aforementioned nearly vertical light refers to greater than or equal to 0 degrees and less than or equal to 30 degrees, for example, 30 degrees, 20 degrees, 10 degrees, 5 degrees. The aforementioned high-angle light refers to greater than or equal to 30 degrees, for example, 50 degrees, 60 degrees, 70 degrees, 80 degrees, 90 degrees. The aforementioned high-angle side view refers to the angle between the human eye and the 0-degree direction being greater than 30 degrees.

[0081] On the basis of the above embodiment, the anti-peeping component 20 may further include a first anti-peeping conductive layer 23, a second anti-peeping conductive layer 24 and a third anti-peeping conductive layer 25, the first anti-peeping conductive layer 23 is located between the first anti-peeping conductive layer 21 and the display substrate 10; the second anti-peeping conductive layer 24 is located between the first anti-peeping conductive layer 21 and the second anti-peeping conductive layer 22, and the first anti-peeping conductive layer 21 switches between a light-transmitting state and a non-light-transmitting state according to the voltage applied between the first anti-peeping conductive layer 23 and the second anti-peeping conductive layer 24; the third anti-peeping conductive layer 25 is located on a side of the second anti-peeping conductive layer 22 away from the second anti-peeping conductive layer 24, and the second anti-peeping conductive layer 22 switches between a light-transmitting state and a non-light-transmitting state according to the voltage applied between the second anti-peeping conductive layer 24 and the third anti-peeping conductive layer 25.

[0082] Since the first anti-peeping layer 21 and the second anti-peeping layer 22 both have a light-transmitting state and a non-light-transmitting state, when the first anti-peeping layer 21 and the second anti-peeping layer 22 are in the light-transmitting state, users at different viewing angles can all know the displayed information. At this time, the display panel does not have an anti-peeping effect. Please refer to Figure 1 ,in Figure 1 Schematic diagram of the structure of the display panel when it is in a non-peeping state. When the first anti-peeping layer 21 and the second anti-peeping layer 22 are in a non-light-transmitting state, the anti-peeping component 20 can filter out light with a large viewing angle, and only retains small-angle light emitted nearly vertically, so that users at a large viewing angle cannot receive the image displayed by the display panel. At this time, the display panel has an anti-peeping effect. Please refer to Figure 2 ,in, Figure 2 Therefore, by setting the first anti-peeping layer 21 and the second anti-peeping layer 22 to have a light-transmitting state and a non-light-transmitting state, the display panel has a variety of different display effects, making the display panel suitable for a variety of scenarios.

[0083] Since the first anti-peeping layer 21 and the second anti-peeping layer 22 are separated by the second anti-peeping conductive layer 24 , the distance between the first anti-peeping layer 21 and the second anti-peeping layer 22 is increased, which is beneficial to reducing the viewing angle and improving the anti-peeping effect.

[0084] like Figures 1 to 8 As shown, the first light-transmitting region 211 is spaced apart from the first target film layer, and the first target film layer includes at least one of the first anti-peeping conductive layer 23 and the second anti-peeping conductive layer 24. The second light-transmitting region 221 is spaced apart from the second target film layer, and the second target film layer includes at least one of the second anti-peeping conductive layer 24 and the third anti-peeping conductive layer 25.

[0085] Specifically, the discoloration position of the first privacy protection layer 21 is on the surface of one side of the first privacy protection layer 21, see Figure 2 . That is to say, the surface of the first peep-proof layer 21 in contact with the first peep-proof conductive layer 23 or the second peep-proof conductive layer 24 is a discoloration surface, and the discoloration surface will only change color when it contacts the first peep-proof conductive layer 23 or the second peep-proof conductive layer 24. The first light-transmitting area 211 is spaced from the first target film layer to prevent the first peep-proof layer 21 from becoming non-transparent at the first light-transmitting area 211, so as to prevent the first light-transmitting area 211 from blocking light. The discoloration position of the second peep-proof layer 22 is on the surface of one side of the second peep-proof layer 22, that is, the surface of the second peep-proof layer 22 in contact with the second peep-proof conductive layer 24 or the third peep-proof conductive layer 25 is a discoloration surface, and the discoloration surface will only change color when it contacts the second peep-proof conductive layer 24 or the third peep-proof conductive layer 25. The second light-transmitting area 221 is spaced from the second target film layer to prevent the second peep-proof layer 22 from becoming non-transparent at the second light-transmitting area 221, so as to prevent the second light-transmitting area 221 from blocking light.

[0086] It should be noted that when the surface where the first peep-proof layer 21 contacts the first peep-proof conductive layer 23 is a discolorable surface, the first target film layer includes the first peep-proof conductive layer 23. When the surface where the first peep-proof layer 21 contacts the second peep-proof conductive layer 24 is a discolorable surface, the first target film layer includes the second peep-proof conductive layer 24. When the surface where the second peep-proof layer 22 contacts the second peep-proof conductive layer 24 is a discolorable surface, the second target film layer includes the second peep-proof conductive layer 24, and when the surface where the second peep-proof layer 22 contacts the third peep-proof conductive layer 25 is a discolorable surface, the second target film layer includes the third peep-proof conductive layer 25.

[0087] exist Figure 2 In the specific embodiment shown, the surface of the first peep-proof layer 21 in contact with the first peep-proof conductive layer 23 is a color-changing surface, and the first peep-proof layer 21 is spaced apart from the first peep-proof conductive layer 23 at the position of the first light-transmitting area 211, and the first peep-proof layer 21 can be in contact with the second peep-proof conductive layer 24 at the position of the first light-transmitting area 211, or can be spaced apart, and no specific restrictions are made here. The surface of the second peep-proof layer 22 in contact with the third peep-proof conductive layer 25 is a color-changing surface, and the second peep-proof layer 22 is spaced apart from the third peep-proof conductive layer 25 at the position of the second light-transmitting area 221, and the second peep-proof layer 22 can be in contact with the second peep-proof conductive layer 24 at the position of the second light-transmitting area 221, or can be spaced apart, and no specific restrictions are made here.

[0088] like Figures 1 to 8 As shown, the anti-peeping component 20 further includes a first optical adhesive layer 30 for isolating the first anti-peeping layer 21 from the first anti-peeping conductive layer 23. The first optical adhesive layer 30 is located between the first anti-peeping layer 21 and the first anti-peeping conductive layer 23, and the orthographic projection of the first optical adhesive layer 30 on the display substrate 10 coincides with the orthographic projection of the first light-transmitting area 211 on the display substrate 10, so that the first optical adhesive layer 30 separates the first anti-peeping layer 21 from the first anti-peeping conductive layer 23 in the first light-transmitting area 211, thereby ensuring light transmission at the first light-transmitting area 211.

[0089] like Figures 1 to 8 As shown, the anti-peeping component 20 further includes a second optical adhesive layer 40 for isolating the second anti-peeping layer 22 from the third anti-peeping conductive layer 25. The second optical adhesive layer 40 is located between the second anti-peeping layer 22 and the third anti-peeping conductive layer 25, and the orthographic projection of the second optical adhesive layer 40 on the display substrate 10 coincides with the orthographic projection of the second light-transmitting area 221 on the display substrate 10, so that the second optical adhesive layer 40 separates the second anti-peeping layer 22 from the third anti-peeping conductive layer 25 in the second light-transmitting area 221, thereby ensuring light transmission at the second light-transmitting area 221.

[0090] As a preferred embodiment, based on the above embodiment, the first optical adhesive layer 30 includes a plurality of first adhesive blocks 31, the plurality of first adhesive blocks 31 are embedded in the first anti-peeping layer 21, and the first adhesive blocks 31 are in contact with the first anti-peeping conductive layer 23, see Figures 1 to 8. The first glue block 31 separates the first peep-proof layer 21 from the first peep-proof conductive layer 23 in the first light-transmitting area 211, so that the first peep-proof layer 21 is light-transmitting at the first glue block 31. In addition, the first glue block 31 is in contact with the first peep-proof conductive layer 23, which is beneficial to the production of the first glue block 31 and the subsequent leveling. A plurality of second glue blocks 41 are embedded in the third peep-proof conductive layer 25, and the second glue block 41 is in contact with the second peep-proof layer 22. The second glue block 41 separates the second peep-proof layer 22 from the third peep-proof conductive layer 25 in the second light-transmitting area 221, so that the second peep-proof layer 22 is light-transmitting at the second glue block 41. In addition, such a setting process is simple, which is beneficial to the production of the second glue block 41 and the third peep-proof conductive layer 25.

[0091] For example, see Figure 1 and Figure 2 The first privacy layer 21 has a plurality of first grooves 212, each of which is filled with a first glue block 31, and the first glue block 31 is in contact with the first privacy conductive layer 23. The second optical adhesive layer 40 includes a plurality of second glue blocks 41, which are embedded in the third privacy conductive layer 25, and the second glue blocks 41 are in contact with the second privacy layer 22. It can be understood that the surface of the third privacy conductive layer 25 facing the second privacy layer 22 has a plurality of fourth grooves 251, and each second glue block 41 is correspondingly embedded in each fourth groove 251.

[0092] In a specific implementation, the first optical adhesive layer 30 can be formed on the first privacy-preventing conductive layer 23 by a single patterning process, and the second optical adhesive layer 40 can be formed on the second privacy-preventing layer 22 by a single patterning process.

[0100] As an optional solution, based on the above embodiment, the display panel further includes a touch electrode, and the first anti-peeping conductive layer 23 or the third anti-peeping conductive layer 25 is in the same layer as the touch electrode. This arrangement enables the display panel to have both an anti-peeping function and a touch function, and the first anti-peeping conductive layer 23 or the third anti-peeping conductive layer 25 can be manufactured simultaneously with the touch electrode, which is conducive to simplifying the manufacturing process. For example, the touch electrode is used as the first anti-peeping conductive layer 23. For another example, the touch electrode is used as the third anti-peeping conductive layer 25.

[0101] As an optional solution, based on the above embodiment, the first anti-peeping conductive layer 23 is connected to the third anti-peeping conductive layer 25. This arrangement is conducive to applying the same voltage to the first anti-peeping conductive layer 23 and the third anti-peeping conductive layer 25, and is conducive to controlling the first anti-peeping layer 21 and the second anti-peeping layer 22 to switch between the light-transmitting state and the non-light-transmitting state.

A portion of the second anti-peeping conductive layer 24 is coated on one side of the first anti-peeping layer 21, so that the second anti-peeping conductive layer is electrically connected to the structure on the display substrate 10.

[0103] In addition, the first anti-peeping layer 21 and the second anti-peeping layer 22 may be connected or not connected, and there is no specific limitation here. It only needs to ensure that the display panel can play an anti-peeping effect in the anti-peeping state.

[0104] As an optional solution, based on the above embodiment, the first privacy layer 21 and the second privacy layer 22 include organic color-changing materials. The use of mail color-changing materials has a simple manufacturing process and is conducive to forming the first optical adhesive layer 30 and the second optical adhesive layer 40 by patterning process.

[0105] On the basis of the above embodiment, the display substrate 10 further includes a base substrate 12 and a pixel defining layer 13 disposed on the base substrate 12, the pixel defining layer 13 having a plurality of pixel openings 131, and a portion of the light emitting unit 11 is located in the pixel openings 131. The light emitting unit 11 includes a first electrode 111, a light emitting layer 112, and a second electrode 113, the first electrode 111 being located between the pixel defining layer 13 and the base substrate 12, the light emitting layer 112 being located in the pixel openings 131, and the second electrode 113 being disposed on a side of the light emitting layer 112 away from the first electrode 111.

[0106] On the basis of the above-mentioned embodiment, the second electrodes 113 of the plurality of light-emitting units 11 are an integrally formed structure.

[0107] exist Figure 1 In the specific embodiment shown, the display substrate 10 further includes an encapsulation layer 14 , which is disposed on a side of the second electrode 113 away from the base substrate 12 , and the peek-proof component 20 is disposed on a side of the encapsulation layer 14 away from the base substrate 12 .

[0108] Specifically, the encapsulation layer 14 includes a first encapsulation sublayer 141 and a second encapsulation sublayer 142.

The first encapsulation sublayer 141 and the second encapsulation sublayer 142 can be organic encapsulation layers or inorganic encapsulation layers, and no specific limitation is made here.

[0109] On the basis of the above embodiment, the display substrate 10 further includes a third optical adhesive layer 15 , which is disposed between the encapsulation layer 14 and the anti-peeping component 20 , so as to facilitate the connection between the display substrate 10 and the anti-peeping component 20 .

[0110] Embodiment 2

[0111] This embodiment provides a display device, which can be an OLED display device and a television with an OLED display device, a digital camera, a mobile phone, a tablet computer, a smart watch, an e-book, a navigator, or any other product or component with a display function.

[0112] The display device comprises: the display panel of the above-mentioned embodiment 1. The structure, function and implementation of the display panel are the same as those of the embodiment 1, and will not be described in detail here.

[0113] The display device of this embodiment includes a display panel. By setting a first anti-peep layer 21 and a second anti-peep layer 22 in the display panel, the total thickness of the color changing area of ​​the anti-peep component is increased, thereby reducing the emission of part of the large-angle light, reducing the viewing angle, and improving the anti-peep effect. In addition, the double-layer anti-peep layer can improve the absorption of large-angle light, prevent large-angle light from being emitted from adjacent light-emitting units 11, and further reduce the risk of cross-color. In addition, since the first light-transmitting area 211 and the second light-transmitting area 221 both cover the corresponding light-emitting unit 11, it is ensured that the light emitted nearly vertically by the light-emitting unit 11 can pass through the first light-transmitting area 211 and the second light-transmitting area 221 to emit the display panel, so that users who look directly at the display panel can observe the displayed image, while users who look at the display panel from the side at a large angle cannot see the displayed image, thereby achieving the purpose of anti-peeping.

[0114] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
