However, these films have low transmittance, which affects the user's visual experience. Furthermore, thick films can easily render fingerprints on electronic devices ineffective, preventing users from unlocking or making payments, thus impacting the user experience. Furthermore, anti-peeping films restrict their use in certain environments, making it difficult to share content displayed on electronic device screens with friends. Summary of the Invention

[0059] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, like numbers in different figures represent like or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present invention, as detailed in the appended claims.

[0060] In the related art, in order to solve the problems existing in anti-peeping films, electronic manufacturers have proposed an anti-peeping film, including an upper electrode layer and a lower electrode layer arranged one above the other, and a plurality of first adjustment layers and second adjustment layers arranged in sequence between the upper electrode layer and the lower electrode layer. The width of the first adjustment layer is greater than the width of the second adjustment layer. When powered on, the transmittance of the first adjustment layer is lower than the first threshold, and the second threshold of the second adjustment layer is greater than the second threshold. The second threshold is greater than or equal to the first threshold, thereby achieving an anti-peeping effect. However, the anti-peeping effect of the above method is not ideal, and setting the first adjustment and second adjustment layers with different thresholds makes the screen have different transmittances, which affects the user's viewing experience. At the same time, if the area of ​​the upper electrode layer and the lower electrode layer is too large, it affects the display area of ​​the screen. If the area is too small, the electrical connection is unstable and easily fails, and the anti-peeping effect cannot be achieved. When the anti-peeping film is set on the screen, it is easy to collapse, affecting the flatness of the screen.

[0061] The present disclosure proposes an anti-peeping screen, including an anti-peeping layer, the anti-peeping layer including a plurality of spaced support portions and a plurality of spaced conductive color-changing portions, the support portions and the conductive color-changing portions being alternately arranged in sequence along a first preset direction. The conductive color-changing portion includes a color-changing film layer, the color-changing film layer being made of an electrochromic material, and the color-changing film layer changes color when energized. The present disclosure utilizes the alternate arrangement of the support portions and the conductive color-changing portions to provide a supporting effect for the conductive color-changing portion, thereby preventing the conductive color-changing portion from collapsing and ensuring that the conductive color-changing portion can be used normally. By utilizing the conductive color-changing portion to change color when energized, the transmittance of the screen is reduced, the user's privacy is protected, and an anti-peeping function is achieved.

[0062] In an exemplary embodiment, Figure 1 、 Figure 2As shown, the anti-peeping screen includes an anti-peeping layer 1, which includes a plurality of spaced support portions 11 and a plurality of spaced conductive color-changing portions 12. The support portions 11 and the conductive color-changing portions 12 are arranged along a first preset direction (refer to Figure 1 The support portion 11 is connected to the conductive color changing portion 12, and the support portion 11 (refer to Figure 1 The height of the conductive color-changing portion along the second preset direction (as shown in the Y-axis) is the same as the height of the conductive color-changing portion, and the second preset direction is perpendicular to the first preset direction.

[0063] When other structures of the privacy screen are covered on the privacy layer 1, the support portion 11 can provide support for the conductive color-changing portion 12, preventing the conductive color-changing portion 12 from collapsing and ensuring the flatness of the conductive color-changing portion 12. The support portion 11 is made of, for example, transparent glass material, so that the support portion 11 has good light transmittance and supporting strength.

[0064] In this embodiment, if Figure 1 、 Figure 2 As shown, the conductive color-changing portion 12 includes a color-changing film layer 121 made of an electrochromic material. When powered, the color-changing film layer 121 changes color. The electrochromic material can be inorganic or organic. Inorganic electrochromic materials include transition metal oxides such as tungsten oxide, molybdenum oxide, nickel oxide, cobalt oxide, and Prussian blue. Organic electrochromic materials include conductive polymers such as polyaniline, polythiophene, polypyrrole, viologens, and bipyridine. The specific choice of inorganic or organic electrochromic material depends on the actual design.

[0065] In this embodiment, if Figure 1-Figure 3 As shown, the voltage generated in the energized state is inversely proportional to the transmittance of the color-changing film layer 121. When a positive voltage is applied to the color-changing film layer 121, its transmittance decreases. The color-changing film layers 121 within the multiple conductive color-changing sections 12 act as vertical shields spaced apart from each other, separating adjacent conductive color-changing sections 12 from each other and forming blind spots to achieve a privacy protection function. When the color-changing film layer 121 is not energized, it is colorless and has high transmittance, thereby increasing the screen's visible range and ensuring the proper brightness and transmittance of the privacy screen.

[0066] In this embodiment, if Figure 1 、 Figure 2As shown, the color-changing film layer 121 includes a first color-changing film body 1211 and a second color-changing film body 1212. There is a preset distance between the first color-changing film body 1211 and the second color-changing film body 1212, and the preset distance is 0.25mm-10mm. When the anti-peeping function is activated, the preset distance formed between the first color-changing film body 1211 and the second color-changing film body 1212 limits the viewing angle α between the first color-changing film body 1211 and the second color-changing film body 1212. Within the viewing angle α, the user can normally view the interface displayed on the anti-peeping screen. Beyond the viewing angle α, it is a non-visible area, which meets the user's anti-peeping needs and improves the security of personal privacy. Among them, the viewing angle α can be, for example, 25°-60°.

[0067] In the initial design stage, the viewing angle α between the first color-changing film 1211 and the second color-changing film 1212 can be adjusted by adjusting the preset distance formed between the first color-changing film 1211 and the second color-changing film 1212 .

[0068] In an exemplary embodiment, Figure 2 As shown, the privacy screen includes an anti-peeping layer 1, which includes multiple supporting portions 11 and multiple conductive color-changing portions 12. The conductive color-changing portions 12 include a color-changing film layer 121, which includes a first color-changing film body 1211 and a second color-changing film body 1212. The arrangement of the supporting portions 11 and the conductive color-changing portions 12, as well as the specific structure of the conductive color-changing portions 12, have been described in detail in the above embodiments and will not be repeated here.

[0069] The difference in this embodiment is that Figure 2 As shown, the conductive color-changing portion 12 includes a transparent adhesive layer 122 and two first conductive units 123, which are connected by the transparent adhesive layer 122. The transparent adhesive layer 122 can increase the adhesion with other structural layers of the privacy screen, improving the connection effect. The transparent adhesive layer 122 can be made of transparent OCA (Optically Clear Adhesive), for example, to ensure colorless transparency, high light transmittance, good bonding strength, and a controlled thickness, uniform spacing, UV resistance, and long-term use without yellowing, peeling, or deterioration.

[0070] Each first conductive unit 123 is connected to the corresponding support part 11 respectively. The height of the first conductive unit 123 along the second preset direction is the same as the height of the support part 11, which increases the effective connection area between the first conductive unit 123 and the color-changing film layer 121, ensuring that the color-changing film layer 121 can change color normally when powered on.

[0071] In this embodiment, if Figure 2As shown, the first color-changing film 1211 is disposed within one of the first conductive units 123, and the second color-changing film 1212 is disposed within the other first conductive unit 123. Voltage is applied to the first color-changing film 1211 and the second color-changing film 1212 through the first conductive units 123. The first conductive units 123 can be made of materials such as copper and platinum to provide good electrical conductivity.

[0072] The first conductive unit 123 includes two first electrode layers, and the first color-changing film 1211 is sandwiched between the two first electrode layers of one of the first conductive units 123 .

[0073] In one example, the two first electrode layers are the first positive electrode layer 1231 and the first negative electrode layer 1232, the first color-changing film body 1211 has a first side and a second side, the first positive electrode layer 1231 is attached to the first side of the first color-changing film body 1211, and the first negative electrode layer 1232 is attached to the second side of the first color-changing film body 1211, or the first positive electrode layer 1231 is attached to the second side of the first color-changing film body 1211, and the first negative electrode layer 1232 is attached to the first side of the first color-changing film body 1211, forming a complete circuit.

[0074] The second color-changing film 1212 is sandwiched between two first electrode layers of another first conductive unit 123 . The specific configuration is the same as in the above example and will not be repeated here.

[0075] In the privacy screen of this embodiment, the first color-changing film 1211 and the second color-changing film 1212 are respectively sandwiched in the corresponding first conductive unit 123, and the first color-changing film 1211 and the second color-changing film 1212 are controlled separately, making the color change more reliable.

[0076] In an exemplary embodiment, Figure 1 As shown, the privacy screen includes an anti-peeping layer 1, which includes multiple supporting portions 11 and multiple conductive color-changing portions 12. The conductive color-changing portions 12 include a color-changing film layer 121, which includes a first color-changing film body 1211 and a second color-changing film body 1212. The arrangement of the supporting portions 11 and the conductive color-changing portions 12, as well as the specific structure of the conductive color-changing portions 12, have been described in detail in the above embodiments and will not be repeated here.

[0077] The difference in this embodiment is that the conductive color-changing portion 12 includes a conductive medium layer 124 and two second electrode layers 125. The second electrode layers 125 can be made of materials such as copper and platinum to have good conductivity. The conductive medium layer 124 is a conductive electrolyte.

[0078] The first color-changing film 1211 and the second color-changing film 1212 are disposed between the two second electrode layers 125 . The first color-changing film 1211 is connected to the second color-changing film 1212 via the conductive medium layer 124 , thereby achieving electrical conductivity of the first color-changing film 1211 and the second color-changing film 1212 .

[0079] In an example, Figure 1 As shown, the two second electrode layers 125 are respectively a second positive electrode layer 1251 and a second negative electrode layer 1252, forming a complete circuit. The second positive electrode layer 1251 is fixedly connected to the first color-changing film 1211 and the corresponding support portion 11, respectively, and the second positive electrode layer 1251 is fixedly connected to the second color-changing film 1212 and the corresponding support portion 11, respectively, simplifying the anti-peep screen structure.

[0080] The anti-peeping screen in this embodiment simplifies the anti-peeping screen structure and improves operability.

[0081] In an exemplary embodiment, Figure 1 、 Figure 2 As shown, the privacy screen 1 includes a supporting substrate 13. Multiple support portions 11 and multiple conductive color-changing portions 12 are stacked on the supporting substrate 13 along a second predetermined direction to prevent overflow of the conductive medium layer 124 or the transparent adhesive layer 122 and affect other structures. The supporting substrate 13 is made of, for example, glass to improve its transmittance and ensure proper operation of the privacy screen.

[0082] In this embodiment, if Figure 1 、 Figure 2 、 Figure 6 As shown, the anti-peeping screen includes a display screen, which is fixedly connected to the anti-peeping layer 1 to realize the anti-peeping function of the display screen.

[0083] In an example, refer to Figure 4 As shown, the display screen can be, for example, an OLED screen 2 (Organic Light-Emitting Diode), also known as an organic electric laser display or an organic light-emitting semiconductor (Organic Electroluminescence Display, OLED). The OLED screen 2 is a current-type organic light-emitting device, which is a phenomenon of luminescence caused by the injection and recombination of carriers, and the luminous intensity is proportional to the injected current. Under the action of the electric field, the holes generated by the anode and the electrons generated by the cathode of the OLED screen 2 will move, and are injected into the hole transport layer and the electron transport layer respectively, and migrate to the light-emitting layer. When the two meet in the light-emitting layer, energy excitons are generated, thereby exciting the light-emitting molecules to ultimately produce visible light, thereby realizing the display function of the display screen.

[0084] The OLED screen 2 includes a first cover layer 21, a first polarizing layer 22, a first light-transmitting layer 23, a light-emitting layer 24, and a substrate layer 25, which are stacked in sequence along a second preset direction. The first cover layer 21 is made of glass, the first polarizing layer 22 is a polarizer, the first light-transmitting layer 23 is ENACP glass, which has high strength and impact resistance, and the substrate layer 25 is TFT glass.

[0085] The anti-peep layer 1 can be arranged between any two adjacent layers of the OLED screen 2. For example, the anti-peep layer 1 can be arranged between the first cover layer 21 and the first polarizing layer 22, or the anti-peep layer 1 can also be arranged between the first polarizing layer 22 and the first light-transmitting layer 23, as long as the anti-peep layer 1 is located above the light-emitting layer 24.

[0086] In another example, refer to Figure 5 As shown, the display screen may be an LCD screen 3, which is a liquid crystal display (LCD).

[0087] The LCD screen 3 includes a second cover layer 31, a second polarizing layer 32, a second light-transmitting layer 33, a liquid crystal layer 34, a third light-transmitting layer 35, a third polarizing layer 36, and a backlight module 37, which are stacked in sequence along a second predetermined direction. The second cover layer 31 is made of glass, the second polarizing layer 32 and the third polarizing layer 36 are both polarizers, and the liquid crystal layer 34 is an L / C liquid crystal cell.

[0088] The LCD screen 3 has a liquid crystal layer 34 placed between the second light-transmitting layer 33 and the third light-transmitting layer 35. The third light-transmitting layer 35 is provided with TFTs (thin-film transistors), and the second light-transmitting layer 33 is provided with color filters. The rotation direction of the liquid crystal molecules is controlled by changing the signal and voltage on the TFT, thereby controlling whether polarized light is emitted from each pixel to achieve the display purpose.

[0089] Among them, the anti-peep layer 1 can be arranged between any two adjacent layers of the LCD screen 3. For example, the anti-peep layer 1 can be arranged between the second cover layer 31 and the second polarizing layer 32, or the anti-peep layer 1 can be arranged between the third light-transmitting layer 35 and the third polarizing layer 36, as long as it is located above the backlight module 37.

[0090] The privacy screen proposed in this disclosure controls the transmittance of the color-changing film by controlling the input voltage, thereby improving the security of the display interface, enhancing privacy, and preventing peeping from nearby people. Compared to conventional adhesive privacy films, this disclosure can reduce the impact of the privacy layer on screen brightness during normal use, improving the user experience.

[0091] The color-changing film layer has a preset distance between the first and second color-changing film bodies, which limits the viewing angle between the first and second color-changing film bodies. By adjusting the preset distance, the viewing angle can be adjusted to provide a more suitable viewing angle for the user.

[0092] Anti-peeping screens can be used in different types of display screens, have strong applicability, meet the versatility of anti-peeping screens, and enhance market competitiveness.

[0093] The present disclosure also provides an electronic device, which includes an anti-peeping screen as described in any of the above embodiments, thereby realizing an anti-peeping function of the electronic device and improving the security of the electronic device. The electronic device may be, for example, a mobile phone, a tablet computer, a wearable device, etc.

[0094] This disclosure also provides an anti-peeping method for an electronic device with an anti-peeping screen, such as a mobile phone, tablet computer, or wearable device. The electronic device includes an anti-peeping screen, a front-facing camera module, and a control chip. The anti-peeping screen includes an anti-peeping layer. The control chip is electrically connected to the anti-peeping screen, enabling the control chip to control the anti-peeping screen.

[0095] like Figure 7 As shown, the anti-peeping method in this embodiment includes:

[0096] S110: Obtain a start instruction input by a user.

[0097] In this step, the control chip obtains a startup instruction input by the user, wherein the startup instruction can be a startup instruction for turning on the anti-peeping layer or a startup instruction for turning off the anti-peeping layer.

[0098] S120 : Based on the startup instruction, supply power to the anti-privacy layer included in the anti-privacy screen to start an anti-privacy function of the anti-privacy layer.

[0099] In this step, the control chip determines the operating mode of the privacy layer based on the startup command. If the startup command is to turn on the privacy layer, power is supplied to the privacy layer, applying a positive voltage to activate the privacy layer's privacy protection function and reduce the viewing angle of the privacy screen. If the startup command is to turn off the privacy layer, power is stopped to disable the privacy layer's privacy protection function and increase the viewing angle of the privacy screen.

[0100] The method in this embodiment is based on a startup instruction, and supplies power to the privacy protection layer to apply a voltage to determine the transmittance of the privacy protection layer. The method is simple to execute and easy to operate.

[0101] The present disclosure also provides an anti-peeping method applicable to electronic devices having an anti-peeping layer, such as mobile phones, tablet computers, and wearable devices. The electronic device includes an anti-peeping screen, a control chip, and a front camera module. The anti-peeping screen includes an anti-peeping layer and a display screen, and the front camera module is disposed below the display screen to facilitate image capture. The control chip is electrically connected to the anti-peeping screen and the front camera module, respectively, enabling the control chip to control the front camera module and the anti-peeping screen.

[0102] like Figure 8 As shown, the anti-peeping method in this embodiment includes:

[0103] S210: Acquire facial information.

[0104] In this step, the front camera module is used to collect all facial information within a preset range, and the control chip obtains the facial information collected by the front camera. Wherein, the preset range is, for example, the maximum visible range of the display screen.

[0105] S220: Compare the facial information with pre-stored information to identify the facial information.

[0106] In this step, the control chip compares the facial information with pre-stored information to identify the facial information. The pre-stored information may be, for example, the facial information of the owner that has been pre-entered into the electronic device.

[0107] During the recognition process, if the number of facial information captured by the control chip exceeds a preset number, it can directly determine that a peeper is present. Alternatively, the control chip can compare all facial information with pre-stored information one by one, and if at least one facial information does not match the pre-stored information, it can determine that a peeper is present.

[0108] S230: When the recognition is successful, a prompt message is issued.

[0109] In this step, if the control chip successfully recognizes the device, it will issue a prompt to inquire whether to enable the anti-peeping layer. The prompt may be displayed on the display screen in the form of a pop-up window, and the content of the instruction may be, but is not limited to, whether to enable "anti-peeping mode" or "privacy mode" for the user to select.

[0110] S240: Receive a start instruction input based on the prompt information.

[0111] In this step, the control chip receives a startup instruction input based on the prompt information. The startup instruction input based on the prompt information can be based on, for example, a user selection of "yes", a user selection of "no", or a user selection of "on".
