[0045] With the continuous development of display technology, the display effects of various display panels are gradually improving. For example, organic light emitting diode (OLED) display panels and display panels using mini light emitting diode (MiniLight Emitting Diode, Mini-LED) devices or microlight emitting diode (MicroLight Emitting Diode, Micro-LED) devices have the advantages of high image quality, power saving, thin body and wide range of applications. They are widely used in various consumer electronic products such as mobile phones, televisions, personal digital assistants, digital cameras, laptops, desktop computers, etc., and have become the mainstream in display devices.

[0046] However, the performance of current display products needs to be improved.

[0047] The present application provides a display device, which may include but is not limited to mobile phones, tablets, laptops, desktops, terminals, interactive displays, digital audio and video devices, Internet of Things devices, etc. Among them, interactive displays may include interactive whiteboards, digital advertising interactive screens, and game interactive displays, etc., and Internet of Things devices may include smart home devices and smart wearable devices, etc. Among them, the display device may include a display panel, and the display device may provide a display interface and touch input through the display panel to realize corresponding functions.

[0049] The display device 1 can be an ordinary mobile phone, a feature phone or a smart phone. The smart phone can be a flat screen phone, a curved screen phone or a foldable phone, etc. The display device 1 is provided with a display panel 2, and the display panel 2 can be arranged at the head, middle or tail of the display device 1. The display panel 2 can be used for information display of the display device 1. For example, the display panel 2 can be used as the visual information display part of the display device 1.

The display device 1 can also have an outer shell, and the display panel 2 is installed in the outer shell. The outer shell can protect the display panel 2 and reduce the risk of damage to the display panel 2 by external force.

[0050] Please refer to Figure 2-Figure 5 , Figure 2 is a schematic diagram of a display panel from a first viewing angle according to one or more embodiments; Figure 3 is a schematic diagram of a display panel from a second viewing angle according to one or more embodiments; Figure 4 is based on Figure 3 The schematic structural diagram of the first conductive film of the display panel shown is in a powered-on state; Figure 5 is based on Figure 3 The structure diagram of the second conductive film of the display panel shown is in a powered-on state.

[0051] To solve the above problems, the present application provides a display panel 2, which includes an anti-peeping component 10 and a plurality of pixel units 30. The anti-peeping component 10 is arranged to form a plurality of pixel spaces 11; the plurality of pixel units 30 are arranged corresponding to the plurality of pixel spaces 11; wherein the anti-peeping component 10 includes a light-shielding fluid 12 and a first conductive film 13, the first conductive film 13 forms a receiving space 131, the light-shielding fluid 12 is located in the receiving space 131, the light-shielding fluid 12 can be sunk in the receiving space 131 when the first conductive film 13 is not powered on, so that the pixel unit 30 emits a light beam at a first output angle x1, and the light-shielding fluid 12 can be adsorbed on the surface of the first conductive film 13 when the first conductive film 13 is powered on, so that the pixel unit 30 emits a light beam at a second output angle x2, and the first output angle x1 is greater than the second output angle x2.

[0052] The anti-peeping component 10 can be surrounded to form a plurality of pixel spaces 11, and the plurality can refer to two, three, four or more numbers. The plurality of pixel spaces 11 can be spaced or connected to each other. In some application scenarios, the plurality of pixel spaces 11 can be arranged in an array. For example, the plurality of pixel spaces 11 are arranged in a matrix array. The number of pixel spaces 11 formed by the anti-peeping component 10 is six, which are evenly spaced and arranged in the form of three rows and two columns. The plurality of pixel units 30 are arranged corresponding to the plurality of pixel spaces 11, and each pixel unit 30 can be arranged corresponding to each pixel space 11. In some application scenarios, the plurality of pixel units 30 can also be arranged corresponding to a pixel space 11, for example, two pixel units 30 are arranged corresponding to the same pixel space 11, etc. It can be understood that the pixel unit 30 can emit a light beam, and the light-emitting colors of the plurality of pixel units 30 can be different. For example, the light-emitting colors of some pixel units 30 are red, the light-emitting colors of some pixel units 30 are green, and the light-emitting colors of some pixel units 30 are blue. It should be noted that the color of the light emitted by the pixel unit 30 is not limited to red, green, and blue, but may also be yellow or other colors, which are not limited here.

[0053] The anti-peeping component 10 includes a light-shielding fluid 12 and a first conductive film 13. The first conductive film 13 is formed with a receiving space 131, and the light-shielding fluid 12 is located in the receiving space 131. The light-shielding fluid 12 may have a certain color, for example, the light-shielding fluid 12 may be black. It is understandable that the light-shielding fluid 12 can block the light beam emitted by the pixel unit 30. The light-shielding fluid 12 may include but is not limited to liquid or tiny solid particles. The material of the first conductive film 13 may include but is not limited to indium tin oxide (ITO) and the like. The first conductive film 13 is a transparent material, and the light beam emitted by the pixel unit 30 can penetrate the first conductive film 13. The shape formed by the first conductive film 13 may include but is not limited to a regular trapezoid, an inverted trapezoid, a rectangle, a square, and the like.

[0054] The light-shielding fluid 12 can be sunk into the accommodating space 131 when the first conductive film 13 is not powered, so that the pixel unit 30 emits a light beam at a first output angle x1. When the first conductive film 13 is not powered, it can be considered that the attraction of the first conductive film 13 to the light-shielding fluid 12 is insufficient to cause the light-shielding fluid 12 to be adsorbed on the first conductive film 13. In some application scenarios, the first conductive film 13 has no attraction to the light-shielding fluid 12 when it is not powered. The light-shielding fluid 12 sunk into the accommodating space 131 may mean that the light-shielding fluid 12 is located at the bottom of the accommodating space 131. For example, the light-shielding fluid 12 can be sunk to the bottom of the accommodating space 131 downstream in the gravity direction under the action of its own gravity, so that when the first conductive film 13 is not powered, the pixel unit 30 emits a light beam at the first output angle x1. It can be understood that when the first conductive film 13 is not energized, the light-shielding fluid 12 may be partially located in the optical path of the light beam emitted by the pixel unit 30 and block at least part of the light beam; it may also not interfere with the optical path of the light beam emitted by the pixel unit 30, thereby not blocking the light beam emitted by the pixel unit 30, so that the light beam emitted by the pixel unit 30 is completely emitted through the first conductive film 13.

[0055] The light-shielding fluid 12 can be adsorbed on the surface of the first conductive film 13 when the first conductive film 13 is powered on, so that the pixel unit 30 emits a light beam at the second output angle x2, and the first output angle x1 is greater than the second output angle x2. When the first conductive film 13 is powered on, the attraction of the first conductive film 13 to the light-shielding fluid 12 is large enough, so that the light-shielding fluid 12 can be adsorbed on the surface of the first conductive film 13, and then part of the light beam emitted by the pixel unit 30 is blocked by the light-shielding fluid 12 after passing through the first conductive film 13, and cannot continue to emit outward, so that the pixel unit 30 can only emit a light beam through the light path that is not blocked by the light-shielding fluid 12, that is, emit a light beam at the second output angle x2. It can be understood that the second output angle x2 is smaller than the first output angle x1. It can be understood that when the display panel 2 is in the anti-peeping mode, the first conductive film 13 can be in the powered state, and when the display panel 2 is not in the anti-peeping mode, the first conductive film 13 can be in the non-powered state.

[0056] Through the above-mentioned embodiment, the anti-peeping component 10 surrounds the pixel unit 30, and the light-shielding fluid 12 in the anti-peeping component 10 can be sunk in the accommodating space 131 when the first conductive film 13 is not powered on, so that the pixel unit 30 emits a light beam at a first output angle x1. The light-shielding fluid 12 can be adsorbed on the first conductive film 13 when the first conductive film 13 is powered on, thereby blocking part of the light beam emitted by the pixel unit 30, so that the pixel unit 30 emits a light beam at a second output angle x2, and the first output angle x1 is greater than the second output angle x2. Therefore, the anti-peeping component 10 can enable the display panel 2 to display at a wide viewing angle when the first conductive film 13 is not powered on, and reduce the display viewing angle of the display panel 2 when the first conductive film 13 is powered on, thereby improving the flexibility of the anti-peeping function of the display panel 2 and reducing the risk of the picture displayed by the display panel 2 being peeped when it does not need to be shared.

[0057] In some embodiments, the anti-peeping component 10 further includes a second conductive film 14, which is disposed in the accommodation space 131, and the second conductive film 14 is spaced apart from the first conductive film 13 to cooperate with the first conductive film 13 to form an accommodation subspace 132, and the light-shielding fluid 12 is located in the accommodation subspace 132; the light-shielding fluid 12 can be sunk in the accommodation subspace 132 when the first conductive film 13 and the second conductive film 14 are not powered on, so that the pixel unit 30 emits a light beam at a first output angle x1, and the light-shielding fluid 12 can be adsorbed on the surface of the second conductive film 14 when the second conductive film 14 is powered on, so that the pixel unit 30 emits a light beam at a third output angle x3, and the first output angle x1 is greater than the third output angle x3. The material of the second conductive film 14 includes but is not limited to indium tin oxide (ITO) and the like. The second conductive film 14 is a transparent material, and the light beam emitted by the pixel unit 30 can penetrate the second conductive film 14. The second conductive film 14 is disposed in the accommodation space 131 and is spaced apart from the first conductive film 13, so that the accommodation space 131 is divided into an accommodation subspace 132 between the second conductive film 14 and the first conductive film 13, and the light-shielding fluid 12 is located in the accommodation subspace 132. The shape of the second conductive film 14 can match the shape of the first conductive film 13, and may include but is not limited to an inverted trapezoid, a regular trapezoid, a rectangle, and a square, etc. In some application scenarios, the first conductive film 13 forms a groove-shaped accommodation space 131, and the second conductive film 14 also forms a groove, and the second conductive film 14 can be spaced apart and sleeved in the accommodation space 131.

[0058] When neither the first conductive film 13 nor the second conductive film 14 is powered on, it can be considered that the attraction of the first conductive film 13 and the second conductive film 14 to the light-shielding fluid 12 is insufficient to cause the light-shielding fluid 12 to be adsorbed on the first conductive film 13 or the second conductive film 14. In some application scenarios, the first conductive film 13 and the second conductive film 14 have no attraction to the light-shielding fluid 12 when they are not powered on. The light-shielding fluid 12 is sunk in the accommodating subspace 132. For example, the light-shielding fluid 12 can be sunk to the bottom of the accommodating subspace 132 downstream in the gravity direction under the action of its own gravity, so that when the first conductive film 13 and the second conductive film 14 are not powered on, the pixel unit 30 emits a light beam at a first emission angle x1. It can be understood that when the first conductive film 13 and the second conductive film 14 are not powered on, the light-shielding fluid 12 may be partially located on the optical path of the light beam emitted by the pixel unit 30 and block at least part of the light beam; it may also not interfere with the optical path of the light beam emitted by the pixel unit 30, thereby not blocking the light beam emitted by the pixel unit 30, so that the light beam emitted by the pixel unit 30 is completely emitted through the first conductive film 13 and the second conductive film 14.

[0059] When the second conductive film 14 is energized, the attraction of the second conductive film 14 to the light-shielding fluid 12 is large enough so that the light-shielding fluid 12 can be adsorbed on the surface of the second conductive film 14, and thus part of the light beam emitted by the pixel unit 30 is blocked by the light-shielding fluid 12 after passing through the first conductive film 13, and cannot continue to emit outward, so that the pixel unit 30 can only emit the light beam through the light path that is not blocked by the light-shielding fluid 12, that is, emit the light beam at the third emission angle x3. It can be understood that the third emission angle x3 is smaller than the first emission angle x1.

[0060] It should be noted that, in some embodiments, at most one of the first conductive film 13 and the second conductive film 14 is in a powered state. For example, when the first conductive film 13 is in a powered state, the second conductive film 14 is not powered; or when the second conductive film 14 is in a powered state, the first conductive film 13 is not powered; or both the first conductive film 13 and the second conductive film 14 are not powered.

[0061] It is understandable that when the display panel 2 is in the anti-peeping mode, the first conductive film 13 or the second conductive film 14 may be in a powered state, and when the display panel 2 is not in the anti-peeping mode, the first conductive film 13 and the second conductive film 14 may be in a non-powered state.

[0062] Preferably, the first light-shielding height D1 of the light-shielding fluid 12 adsorbed on the surface of the first conductive film 13 is adjustable to adjust the size of the second exit angle x2. In the light-emitting direction of the pixel unit 30, the first conductive film 13 may have a certain height dimension, and the first light-shielding height D1 may refer to the height of the light-shielding fluid 12 adsorbed on the surface of the first conductive film 13. Exemplarily, the light-shielding fluid 12 may be adsorbed on the entire height dimension of the first conductive film 13, or may be adsorbed on only a portion of the height dimension of the first conductive film 13, thereby adjusting the blocking angle of the light-shielding fluid 12 on the light beam emitted from the pixel unit 30, and further adjusting the size of the second exit angle x2.

[0063] And / or, the second light-shielding height D2 of the light-shielding fluid 12 adsorbed on the surface of the second conductive film 14 is adjustable to adjust the size of the third exit angle x3. In the light-emitting direction of the pixel unit 30, the second conductive film 14 may have a certain height dimension, and the second light-shielding height D2 may refer to the height of the light-shielding fluid 12 adsorbed on the surface of the second conductive film 14. For example, the light-shielding fluid 12 may be adsorbed on the entire height dimension of the second conductive film 14, or may be adsorbed on only a portion of the height dimension of the second conductive film 14, thereby adjusting the blocking angle of the light-shielding fluid 12 on the light beam emitted from the pixel unit 30, and further adjusting the size of the third exit angle x3.

[0064] Preferably, the range of the third exit angle x3 is greater than the range of the second exit angle x2. It is understandable that when the second light shielding height D2 is the same as the height dimension of the second conductive film 14, the shielding angle of the light shielding fluid 12 on the light beam emitted from the pixel unit 30 is smaller than the shielding angle of the light shielding fluid 12 on the light beam emitted from the pixel unit 30 when the first light shielding height D1 is the same as the height dimension of the first conductive film 13, so the range of the third exit angle x3 may be greater than the range of the second exit angle x2. Exemplarily, when the light shielding fluid 12 completely covers the first conductive film 13, the second exit angle x2 of the pixel unit 30 may be 60 degrees, and when the light shielding fluid 12 completely covers the second conductive film 14, the third exit angle x3 of the pixel unit 30 may be 80 degrees. Thus, the exit angle of the light beam emitted from the pixel unit 30 may be adjusted by adjusting the power-on state of the first conductive film 13 and the second conductive film 14, thereby further improving the flexibility of the display panel 2 in anti-peeping.

[0065] In some embodiments, the light-shielding fluid 12 and the first conductive film 13 and the second conductive film 14 in the powered state carry different charges. Exemplarily, the light-shielding fluid 12 carries one of a positive charge and a negative charge, and the first conductive film 13 and the second conductive film 14 in the powered state carry the other of a positive charge and a negative charge. Preferably, the light-shielding fluid 12 carries a positive charge, and the first conductive film 13 and the second conductive film 14 in the powered state carry a negative charge. Preferably, the light-shielding fluid 12 is positive electronic ink. Thus, it is convenient for the light-shielding fluid 12 to be adsorbed on the first conductive film 13 in the powered state or the second conductive film 14 in the powered state.

[0066] In some embodiments, the display panel 2 includes a substrate 20, a plurality of pixel units 30 are arranged at intervals on the substrate 20, and the anti-peeping component 10 is disposed on the side of the substrate 20 facing the pixel unit 30. The substrate 20 may be a driving substrate, which may be used to drive the pixel unit 30 to emit a light beam, etc. The driving substrate may include a substrate and a driving circuit layer, wherein the substrate may be a glass substrate; or a flexible substrate, wherein the material of the flexible substrate is polyimide (PI). The driving circuit layer may be a TFT circuit layer, and the TFT circuit layer is used to drive the pixel unit 30. The specific TFT circuit layer includes a plurality of driving circuit units arranged in an array, each driving circuit unit may include a thin film transistor (TFT) device and a capacitor. Each driving circuit unit corresponds to a pixel unit 30. Thus, the substrate 20 can provide support and protection for the pixel unit 30 and the anti-peeping component 10. The TFT device is a low temperature polysilicon (LTPS) type or a metal oxide semiconductor (MOS) type, such as a metal oxide semiconductor type of indium gallium zinc oxide (IGZO). In some application scenarios, the anti-peeping component 10 can be directly disposed on a surface of the substrate 20 facing the pixel unit 30 .

[0067] Preferably, the display panel 2 further includes an encapsulation layer 40, which is arranged on the side of the substrate 20 facing the anti-peeping component 10 and covers the pixel unit 30, and the anti-peeping component 10 is arranged on the side of the encapsulation layer 40 away from the substrate 20. The encapsulation layer 40 is used to encapsulate the pixel unit 30, which is conducive to preventing the external moisture and oxygen from affecting the pixel unit 30. The encapsulation layer 40 may include a plurality of inorganic encapsulation film layers and at least one organic encapsulation film layer stacked, and the at least one organic encapsulation film layer is arranged between the plurality of inorganic encapsulation film layers, and the plurality of inorganic encapsulation films form a closed space that seals the organic encapsulation film layer. It should be understood that the inorganic encapsulation film layer can minimize or completely prevent the penetration of moisture, oxygen and / or hydrogen into the pixel unit 30 and the substrate 20. Therefore, as an embodiment, the inorganic encapsulation film layer and the organic encapsulation film layer can be alternately stacked, and the inorganic encapsulation film layer can be set as the uppermost and lowermost layers of the encapsulation unit, and the outermost inorganic encapsulation film layer can completely cover the organic encapsulation film layer, thereby forming a barrier space that can block the entry of water and oxygen. Therefore, the anti-peeping component 10 is disposed on the side of the packaging layer 40 away from the substrate 20, which can improve the packaging effect of the packaging layer 40 and reduce the risk of packaging failure.

[0068] Please refer to Figure 6 , Figure 6 is an equivalent circuit diagram of a first conductive film, a second conductive film, and a third conductive film of a display panel according to one or more embodiments.

[0069] In some embodiments, the anti-peeping component 10 further includes a third conductive film 15, which is disposed on a side of the first conductive film 13 away from the substrate 20, and the third conductive film 15 is spaced apart from the first conductive film 13 and the second conductive film 14, respectively, so as to cooperate with the first conductive film 13 and the second conductive film 14 to form an adsorption electric field. The material of the third conductive film 15 may include but is not limited to indium tin oxide (ITO) and the like. In some application scenarios, the first conductive film 13 and the second conductive film 14 may be electrically connected to the negative electrode of the corresponding driving circuit, respectively, and the third conductive film 15 may be connected to the positive electrode of the driving circuit corresponding to the first conductive film 13 and the second conductive film 14, respectively, so as to cooperate with the first conductive film 13 and the second conductive film 14 to form an adsorption electric field, so as to facilitate the light-shielding fluid 12 to be adsorbed on the surface of the first conductive film 13 and the second conductive film 14 in the energized state. Preferably, the third conductive film 15 serves as the anode of the adsorption electric field, and the first conductive film 13 and the second conductive film 14 serve as the cathode of the electric field. In some other embodiments, the first light-shielding height D1 and the second light-shielding height D2 of the light-shielding fluid 12 can be adjusted by adjusting the electric field strength of the adsorption electric field. For example, the electric field strength of the adsorption electric field can be positively correlated with the first light-shielding height D1 or the second light-shielding height D2.

[0070] In some embodiments, the anti-peeping component 10 further includes an insulating portion 16, which is disposed between the first conductive film 13 and the third conductive film 15 and between the second conductive film 14 and the third conductive film 15, so that the first conductive film 13 and the second conductive film 14 are respectively spaced from the third conductive film 15. Thus, the risk of short circuit between the first conductive film 13 or the second conductive film 14 and the third conductive film 15 can be reduced by the insulating portion 16.

[0071] Please refer to Figure 7 , Figure 7 is a first structural schematic diagram of a display panel according to one or more embodiments.

[0072] In some embodiments, the first conductive film 13 includes a bottom wall portion 133 and a side wall portion 134, the side wall portion 134 is connected to the bottom wall portion 133 and surrounds the bottom wall portion 133 to form a receiving space 131, and the second conductive film 14 abuts against the bottom wall portion 133 and is spaced apart from the side wall portion 134. The first conductive film 13 can form a groove-shaped receiving space 131 through the bottom wall portion 133 and the side wall portion 134, the second conductive film 14 abuts against the bottom wall portion 133 and is spaced apart from the side wall portion 134, and the receiving space 131 can be divided into a receiving subspace 132 between the second conductive film 14 and the side wall portion 134, and the light-shielding fluid 12 can be located in the receiving subspace 132. As a result, the light-shielding fluid 12 between the second conductive film 14 and the bottom wall portion 133 of the first conductive film 13 is reduced, the adsorption efficiency of the light-shielding fluid 12 and the first conductive film 13 and the second conductive film 14 is improved, and at the same time, the structure of the second conductive film 14 is simplified, which is convenient for production and manufacturing, and reduces production costs.

[0074] In some embodiments, the display panel 2 further includes a functional component 50, which is disposed on a side of the anti-peeping component 10 away from the substrate 20. The functional component 50 can be used to provide other functional support for the display panel 2, including but not limited to touch functions, etc. Preferably, the functional component 50 includes a touch module 51 and a display module 52, the touch module 51 is disposed on a side of the anti-peeping component 10 away from the substrate 20, and the display module 52 is disposed on a side of the touch module 51 away from the anti-peeping component 10. The touch module 51 can be used to receive touch signals, etc. Therefore, the display panel 2 can realize functions such as touch input through the functional component 50.

[0075] In some embodiments, the pixel space 11 is filled with a light-transmitting layer 110, and the light-transmitting layer 110 is located on the optical path of the light beam emitted by the pixel unit 30. The light beam emitted by the pixel unit 30 can be transmitted through the light-transmitting layer 110. Preferably, the light-transmitting layer 110 is an organic material. Exemplarily, the material of the light-transmitting layer 110 can be an organic glue. Preferably, the light-transmitting layer 110 is provided with a light-guiding portion 111, and the light-guiding portion 111 is used to converge the light beam emitted by the pixel unit 30. The material of the light-guiding portion 111 can be a material with a high refractive index, including but not limited to an organic material containing zirconium. The light-guiding portion 111 can be configured into a shape capable of converging the light beam. Exemplarily, the light-guiding portion 111 can be configured into a lens shape, so as to facilitate the adjustment of the light path of the light beam emitted by the pixel unit 30, for example, adjusting the original light path 17 originally emitted to the light-shielding fluid 12 to a converging light path 18 within the range of the second emission angle x2 or the third emission angle x3, thereby reducing the risk of the originally blocked light beam being wasted, and reducing the power consumption loss of the display panel 2 in the anti-peeping mode.

Through the above-mentioned implementation, the anti-peeping component 10 can make the pixel unit 30 emit a light beam at the first emission angle x1 or the second emission angle x2, and the first emission angle x1 is greater than the second emission angle x2. Therefore, the anti-peeping component 10 can make the display panel 2 display at a wide viewing angle when the first conductive film 13 is not powered on, and reduce the display viewing angle of the display panel 2 when the first conductive film 13 is powered on, thereby improving the flexibility of the anti-peeping function of the display panel 2 and reducing the risk of the screen displayed by the display panel 2 being peeped when it does not need to be shared.
