[0047] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0048] This application provides a display panel, which includes: a security protection component, a display screen, and a control circuit as described in any of the above embodiments. The display screen includes an encapsulation layer and a substrate. The security protection component is located on the side of the encapsulation layer away from the substrate.

[0049] The control circuit is used to obtain the voltage value required by the security protection component in response to the privacy mode switching command of the security protection component; the security protection component includes electronic ink and multiple ink filling layers;

[0050] The security protection component receives voltage values ​​and controls the flow of electronic ink between multiple ink-filled layers to enable the security protection component to operate in different privacy modes; the display brightness of the screen in the display panel varies in different privacy modes.

[0051] The electronic device may include a display panel, which includes a safety protection component, a display screen, and a control circuit. The display screen includes an encapsulation layer and a substrate, and the safety protection component is located on the side of the encapsulation layer away from the substrate.

[0052] In one embodiment, the display screen further includes a light-emitting layer comprising a plurality of light-emitting units, and safety protection components are arranged around each light-emitting unit.

[0053] In this embodiment of the application, the light-emitting layer in the display screen includes multiple light-emitting units, and the safety protection component can be disposed between every two adjacent light-emitting units in each light-emitting unit in the display panel, that is, the safety protection component is disposed around each light-emitting unit.

[0054] In practical applications, the control device in an electronic device can receive and respond to the privacy mode switching command of the security protection component, obtain the voltage value required by the security protection component, and then input the corresponding voltage value to the security protection component based on the voltage value. Correspondingly, the security protection component generates a corresponding electric field according to the received voltage value to control the flow of electronic ink between multiple ink filling layers, so that the security protection component is in different privacy modes.

[0055] Optionally, at the same time, the electronic ink can be arranged into (i.e. flow into) at least one ink filling layer; the privacy protection mode corresponding to the arrangement of electronic ink in different ink filling layers is different.

[0056] In this embodiment, the display brightness varies depending on the privacy mode of the security protection component. Higher display brightness results in lower power consumption for the electronic device; conversely, lower display brightness results in higher power consumption.

[0057] In one embodiment, the display panel further includes: a touch encapsulation layer, a polarizer layer, and a cover layer; the touch encapsulation layer, polarizer layer, and cover layer are sequentially disposed above the safety protection component. Figure 1 The diagram shows the display screen, safety protection components (first electrode layer, second electrode layer, and static layer), touch encapsulation layer, polarizer layer, and cover plate layer in the display panel; and the positional relationship between the touch encapsulation layer, polarizer layer, and cover plate layer.

[0058] In this embodiment, the Touch Encapsulation (TOE) layer is used to respond to touch input from a finger on the display screen; the Polarizing Film (POL) layer is used to selectively allow light emitted through the display screen to pass through so that the display screen outputs a corresponding image; and the cover plate layer can resist external impacts and directly contact the finger.

[0059] In this embodiment, the control circuit in the display panel can flexibly control and switch different privacy modes of the security protection components according to the actual application scenario. Since the display brightness of the display screen is different in different privacy modes, this can avoid the problems of the display brightness being maintained at a low level for a long time, the touch recognition function of the display screen being less sensitive at low display brightness, and the health hazards to the user's eyes at low display brightness. Therefore, in the actual application of the display screen, the display brightness can be adjusted by flexibly switching different privacy modes of the security protection components, thereby improving the sensitivity of the display screen's touch recognition function, reducing the health hazards to the user's eyes and the power consumption of the electronic device, improving the performance of the electronic device, and improving the user experience, further increasing the versatility of the display panel.

[0060] The specific structure of the security protection component in the display panel is described below. In one embodiment, the security protection component in the display panel includes: electronic ink and multiple ink filling layers; the ink filling layers are connected to each other.

[0061] At least one of the multiple ink filling layers is used to receive the voltage value required by the security protection component in different privacy modes, so as to control the flow of electronic ink between the multiple ink filling layers; the display brightness of the display screen in the display panel is different in different privacy modes.

[0062] In this embodiment, the display screen can be an organic light-emitting diode (OLED) type display screen. The structure of the display screen, from bottom to top, consists of a substrate, a base layer, a driving circuit layer, a light-emitting layer, a conductive layer, and an encapsulation layer.

[0063] The aforementioned security protection component can be a privacy film or electronic paper, and it has a privacy protection function. The security protection component can include electronic ink and multiple different ink-filling layers, with at least two ink-filling layers. Optionally, at any given time, the electronic ink can be arranged (i.e., flow into) at least one ink-filling layer; the privacy protection modes corresponding to the arrangement of electronic ink in different ink-filling layers are different.

[0064] In this embodiment, the display brightness varies depending on the privacy mode of the security protection component. Higher display brightness results in lower power consumption for the electronic device; conversely, lower display brightness results in higher power consumption.

[0065] It should be noted that a control circuit can be incorporated into the electronic device. This control circuit can be installed on the original PCB board within the electronic device, or it can be installed on a new PCB board and integrated into the device. Furthermore, this control circuit is connected to the metal wires of the security protection component to achieve a communication connection. Specifically, in response to the privacy mode switching command of the security protection component on the display panel, the control circuit can obtain the voltage value required by the security protection component and then input the corresponding voltage value to the security protection component.

[0066] In practical applications, the aforementioned security protection component, from bottom to top, can include a first PE protective film layer, a PET layer, a privacy screen layer, a PET layer, an AG hardening layer, and a second PE protective film layer. The first and second PE protective film layers are the outermost layers of the security protection component, possessing excellent waterproof and sealing properties. The PET layer exhibits excellent physical and mechanical properties, superior electrical insulation, creep resistance, fatigue resistance, abrasion resistance, and dimensional stability. The AG hardening layer is highly wear-resistant, highly transparent, highly sensitive, and resistant to fingerprints, dust, and oil stains, making it easy to clean. It effectively eliminates strong glare, improving the outdoor usability of electronic devices, and its special optical properties prevent ultraviolet and infrared penetration. The privacy screen layer can be understood as a louver, used to narrow the viewing angle of the display screen by controlling the angle of light. This is achieved through a parallel arrangement of grating structures (louvers), preventing light at certain angles from passing through and reflecting back to the display screen, thus achieving the function of a privacy screen and reducing the display angle.

[0067] In simple terms, the aforementioned privacy screen layer restricts the visible area of ​​the display screen to effectively prevent the leakage of information output on the screen. For example, if the visible area of ​​the display screen is 60 degrees (meaning any user within a 30-degree radius to the left and right of the main user can see the information output on the screen), then the area outside the 30-degree radius to the left and right of the main user is the privacy screen area. Any user within this area will only see a completely black screen. In other words, the area outside the visible area is the privacy screen area, which can effectively prevent information leakage.

[0068] In this embodiment, the security protection component includes: electronic ink and multiple ink filling layers; the ink filling layers are connected to each other, and at least one of the multiple ink filling layers is used to receive the voltage value required by the security protection component in different privacy modes, so as to control the flow of electronic ink between the multiple ink filling layers. The display brightness of the electronic device screen is different in different privacy modes. This embodiment can flexibly switch different privacy modes of the security protection component according to the application scenario. Since the display brightness of the electronic device screen is different in different privacy modes, it can avoid the problems of the display brightness of the screen being maintained at a low display brightness for a long time, the touch recognition function of the electronic device screen being not sensitive enough under low display brightness, and the health hazards to the user's eyes under low display brightness. Therefore, in practical applications, the display brightness of the electronic device screen can be adjusted by flexibly switching different privacy modes of the security protection component, thereby improving the sensitivity of the touch recognition function of the electronic device screen, the health hazards to the user's eyes, and the power consumption of the electronic device, so as to improve the performance of the electronic device. Moreover, this design can greatly improve the versatility of the security protection component.

[0069] In one embodiment, the different privacy modes include multiple different privacy modes; the multiple ink filling layers include multiple different electrode layers, which are arranged in parallel with each other; at least one of the electrode layers is used to receive a voltage value to control the flow of electronic ink into the at least one layer, so that the security protection component is in a different privacy mode.

[0070] The multiple ink-filling layers in the security protection component may include multiple different electrode layers, and each electrode layer may be arranged in parallel and perpendicular to the light-emitting layer of the display screen; the privacy protection range of the multiple privacy protection modes is different, and the privacy protection angle corresponding to the different privacy protection ranges is greater than 0.

[0071] It should be noted that the aforementioned security protection component has multiple different privacy protection modes, and these different privacy protection modes include multiple different privacy protection levels. In this embodiment, the privacy protection mode of the security protection component is different when electronic ink is arranged in different electrode layers. Specifically, when the security protection component is in the privacy protection mode with the minimum privacy protection range, the electronic ink flows to one corresponding electrode layer (i.e., electronic ink is arranged in one corresponding electrode layer), and no electronic ink is arranged in any of the other electrode layers except for this one electrode layer. When the security protection component is in the privacy protection mode with other privacy protection ranges, the electronic ink flows to two corresponding electrode layers (i.e., electronic ink is arranged in two corresponding electrode layers), and no electronic ink is arranged in any of the other electrode layers except for these two electrode layers.

[0072] In the embodiments of this application, the privacy mode of the minimum privacy range of the security protection component corresponds to one electrode layer, and the privacy mode of the other privacy ranges of the security protection component corresponds to two electrode layers.

[0073] In practical applications, if at least one of the multiple different electrode layers reaches a voltage value, electronic ink can flow into that at least one electrode layer.

[0074] It should be noted that the voltage value of the safety protection component may include the sub-voltage values ​​that need to be input to each electrode layer in the safety protection component during the use of the electronic device. In this embodiment, the sub-voltage value of at least one electrode layer can be a positive voltage value, while the sub-voltage values ​​of other electrode layers can be 0 or negative voltage values. In practical applications, if the sub-voltage value of an electrode layer is positive, the electrode layer can absorb electronic ink, and the electronic ink can flow into the electrode layer; if the sub-voltage value of an electrode layer is 0 or negative, the electrode layer does not absorb electronic ink, and the electronic ink can flow entirely into the other electrode layers.

[0075] Among them, when the security protection component is in different privacy protection modes, the voltage values ​​input to different electrode layers can be different; when the security protection component switches from one privacy protection mode to another privacy protection mode, that is, the electronic ink flows from at least one electrode layer corresponding to one privacy protection mode to at least one electrode layer corresponding to another privacy protection mode.

[0076] In one embodiment, multiple different electrode layers include a first electrode layer and a second electrode layer, which are arranged in parallel and are both perpendicular to the light-emitting layer of the display screen. The first electrode layer and the second electrode layer of the display panel have different dimensions in the vertical direction of the light-emitting layer of the display panel.

[0077] In practical applications, the first electrode layer and the second electrode layer are arranged in parallel, and both the first electrode layer and the second electrode layer are perpendicular to the light-emitting layer of the display screen. This design allows the security protection component to be in a first privacy mode when electronic ink is arranged in the first electrode layer, by blocking the light emitted by the light-emitting layer through the first electrode layer. Alternatively, when electronic ink is arranged in the second electrode layer, the light emitted by the light-emitting layer is blocked through the second electrode layer, thereby allowing the security protection component to be in a second privacy mode.

[0078] Optionally, the dimensions of the first electrode layer and the second electrode layer of the display panel are different in the vertical direction of the light-emitting layer of the display panel. That is, the dimensions (i.e., height) of the first electrode layer are different from the dimensions of the second electrode layer. In this embodiment, the example is that the dimensions of the first electrode layer are smaller than those of the second electrode layer. It should be noted that because the first electrode layer is smaller, the area of ​​light blocking when electronic ink is arranged in the first electrode layer is smaller; because the second electrode layer is larger, the area of ​​light blocking when electronic ink is arranged in the second electrode layer is larger. Naturally, the privacy protection range of the first privacy protection mode is smaller than that of the second privacy protection mode.

[0079] The privacy angle corresponding to the privacy range of the first privacy mode can be 20 degrees, 25 degrees, 40 degrees, etc., and correspondingly, the privacy angle corresponding to the privacy range of the second privacy mode can be 27 degrees, 35 degrees, 48 ​​degrees, etc. In this embodiment, the example is that the privacy angle corresponding to the privacy range of the first privacy mode is equal to 30 degrees and the privacy angle corresponding to the privacy range of the second privacy mode is equal to 60 degrees.

[0080] In one embodiment, there are multiple second electrode layers, each with the same size. The size of the second electrode layer is larger than that of the first electrode layer. The first electrode layer is disposed in the middle of the stationary layer, and each second electrode layer is disposed on both sides of the first electrode layer.

[0081] It should be noted that by placing each of the second electrode layers on both sides of the first electrode layer, when the electronic ink flows into each of the second electrode layers, the security protection component can only protect users within the privacy range corresponding to the second privacy mode, and will not protect users within the privacy range corresponding to the first privacy mode. This allows the corresponding privacy functions of the security protection component in the first privacy mode and the second privacy mode to be independent of each other and not affect each other.

[0082] The light-emitting layer in the display screen can emit light at different angles in all directions. However, if electronic ink is arranged in the corresponding electrode layer, it will block a portion of the light from passing through the electrode layer. At this time, the maximum angle of the light emitted by the light-emitting layer will be reduced, and naturally, the privacy protection range of the security protection component will be reduced.

[0083] like Figure 2 The diagram shown illustrates the flow of electronic ink from the safety protection component to the first electrode layer. Figure 2 Each shaded rectangle represents a light-emitting layer in the display screen, and each layer can emit blue, red, and yellow light. The arrow segments indicate the direction in which the corresponding light is emitted by the light-emitting layer, and the range on both sides of the thin arrow segments is... Figure 2 The privacy protection range of the central security component is defined as follows: the area within the thin arrow segment represents the visible range of the security component; the four rectangles on either side of the shaded rectangle represent the same security component, with the solid black rectangle representing the first electrode layer, the hollow rectangles on either side of the first electrode layer representing the second electrode layer, and the horizontal hollow rectangle representing the static layer. The thick arrow segment is perpendicular to the light-emitting layer; therefore, the angle between the thin and thick arrow segments represents the maximum visible angle (i.e., the maximum angle of light emitted by the light-emitting layer). The entire range within this maximum visible angle is called the maximum visible range of the security component (which can be understood as a cone with the orthocenter of the thick arrow segment and the light-emitting layer as its origin). If the maximum visible angle is 60 degrees, then the privacy protection range of the security component can be the entire range outside the 60-degree cone with the orthocenter of the thick arrow segment and the light-emitting layer as its origin.

[0084] Figure 3 Shown Figure 2 A diagram illustrating the flow of electronic ink from the safety protection component to the second electrode layer. Figure 3 The angle between the thin arrow segment and the thick arrow segment indicates the maximum visible angle. Figure 4 Shown Figure 2 A diagram illustrating the flow of electronic ink to the settling layer in a safety protection component. Figure 4 All areas above the middle static layer and the light-emitting layer are within the visible range of the safety protection components.

[0085] In addition, in actual design, the static layer and the light-emitting layer are not located on the same horizontal plane, but the distance between the static layer and the light-emitting layer is very small, close to being on the same layer; the static layer is located on the side of the encapsulation layer away from the substrate.

[0086] In this embodiment, different privacy modes include multiple privacy protection modes. The multiple ink filling layers in the security protection component include multiple different electrode layers, which are arranged in parallel. At least one of the electrode layers is used to receive voltage values ​​to control the flow of electronic ink into the at least one layer, so that the security protection component is in different privacy protection modes. Based on this, the display brightness of the electronic device screen can be flexibly adjusted, which can reduce the power consumption of the electronic device to a certain extent and improve the performance of the electronic device. Therefore, this design of the security protection component in this embodiment can greatly improve the versatility of the security protection component.

[0087] In one embodiment, the plurality of ink-filled layers in the safety protection component further includes a settling layer, which is vertically connected to each electrode layer.

[0088] In the embodiments of this application, the above-mentioned plurality of ink filling layers may include a stationary layer; the stationary layer is used for dynamically arranging electronic ink, that is, the electronic ink can flow into the stationary layer for arrangement, and can also flow into at least one electrode layer (not in the stationary layer) for arrangement.

[0089] In practical applications, the stationary layer and each electrode layer are vertically connected. Therefore, even after electronic ink is arranged within the stationary layer, it will not block the light emitted by the light-emitting layer. When the electronic ink flows into the stationary layer, the security protection component is in a non-peeping mode. Optionally, the non-peeping mode can also be understood as a privacy mode where the privacy angle of the privacy range is 0 degrees, or a privacy mode where the visible area has an angle of 90 degrees.

[0090] In this embodiment, the multiple ink-filling layers in the security protection component also include a stationary layer, which is vertically connected to each electrode layer. This design allows the electronic ink to flow between the stationary layer and each electrode layer, dynamically controlling the security protection component to switch between different privacy protection modes and no privacy protection mode. When the security protection component is applied to electronic devices, this not only reduces the degree of eye health hazards caused by using electronic devices, but also reduces the power consumption of electronic devices to a certain extent. Furthermore, it increases the display brightness and improves the sensitivity of the display touch recognition function, thereby improving the performance of electronic devices, enhancing the user experience, and further increasing the versatility of electronic devices. Therefore, this design of the security protection component in this embodiment can greatly improve the versatility of the security protection component.

[0091] In the display field, display devices are widely used in electronic devices to output and display related images, videos, text, and other information. In practical applications, electronic devices are often used in public places; therefore, protecting the information output by these devices is particularly important. Related technologies primarily involve setting up security protection components on the display screen of the electronic device to safeguard its output information. However, these technologies often result in low display brightness during the use of these security protection components, leading to higher power consumption and consequently lower performance. Therefore, this application provides a display brightness control method that avoids the display brightness from consistently remaining at the minimum level. The display brightness of the electronic device can be flexibly adjusted during use, thereby reducing power consumption and improving performance to some extent.

[0092] The display brightness control method provided in this application can be applied to electronic devices, such as smartphones, smartwatches, smart bracelets, tablets, laptops, personal computers, and televisions, which have display functions. This embodiment does not limit the specific form of the electronic device. The following embodiments will describe the specific process of the display brightness control method, using an electronic device as the executing entity.

[0093] like Figure 5 The diagram shown is a flowchart illustrating a display brightness control method provided in an embodiment of this application. This method may include the following steps:

[0094] S100: In response to the privacy mode switching command of the security protection component in the display panel, obtain the voltage value required by the security protection component. The security protection component includes electronic ink and multiple ink-filling layers.

[0095] In this embodiment, the electronic device includes a display panel and a security protection component. The display panel includes a display screen, which includes an encapsulation layer and a substrate. The security protection component is located on the side of the encapsulation layer away from the substrate. The security protection component can achieve its privacy function based on the optical principle of venetian blinds; it can be understood as a privacy film or electronic paper. The security protection component has a privacy function. The security protection component can include electronic ink and multiple different ink-filling layers, with at least two ink-filling layers. In this embodiment, the electronic ink can be black particles.

[0096] In practical applications, electronic devices can receive anti-spy mode switching commands from the security protection components attached to the display screen of the main user. They can also detect the distance and angle of each user around the main user from the electronic device based on the built-in distance and angle sensors. Then, based on the distance and / or angle of each user from the electronic device, it can determine whether there is at least one secondary user among the users. If so, it indicates that the information output on the display screen has a protection requirement relative to the secondary user. At this time, the anti-spy mode switching command of the security protection components can be automatically generated based on the angle of each secondary user from the electronic device.

[0097] Optionally, the aforementioned "main user" can be understood as a user directly using the electronic device. The main user can input the privacy mode switching command via voice, gesture, touchscreen, button, keyboard, etc. During the use of the electronic device, the main user can determine whether there is at least one "side user" among the surrounding users based on their distance and / or angle from the electronic device. If so, it indicates that the information output on the display screen requires protection relative to the side user. In this case, the privacy protection range of the security component for the side user can be determined based on the angle of each side user from the electronic device, and then the privacy mode switching command corresponding to the security component can be input to the electronic device based on this privacy protection range.

[0098] The privacy protection range of the security protection component for other users can include the privacy protection angle of the security protection component for other users. This privacy protection angle can be equal to the angle between the other user and the electronic device. Optionally, the angle between the other user and the electronic device can be equal to the angle between the line connecting the main user and the electronic device and the electronic device and the other user. It should be noted that there can be multiple users around the main user, and these multiple users can include at least one other user. The main user has the purpose of preventing privacy from other users.

[0099] In practical applications, if the distance between the user and the electronic device is less than a preset distance threshold, or the angle between the user and the electronic device is less than a preset angle threshold, then the user can be identified as a bystander user; if the distance between the user and the electronic device is greater than a preset distance threshold and the angle between the user and the electronic device is less than a preset angle threshold, then the user can be identified as a bystander user; if the distance between the user and the electronic device is less than a preset distance threshold and the angle between the user and the electronic device is greater than a preset angle threshold, then the user can be identified as a bystander user.

[0100] Upon receiving or acquiring a privacy mode switching command from the security protection component, the electronic device can instruct itself to switch from the current privacy mode to another privacy mode; different privacy modes have different privacy protection ranges. Specifically, in response to the privacy mode switching command from the security protection component on the display panel, the electronic device can first acquire the voltage value that the security protection component needs to input. Optionally, the voltage value that the security protection component needs to input can be a positive voltage value or a negative voltage value.

[0101] It should be noted that during the use of electronic devices, different privacy protection modes of the security protection components in the electronic devices can be dynamically and flexibly switched according to the surrounding environment of the electronic devices and the main user's protection needs for the information output on the display screen; optionally, different privacy protection modes may include privacy protection modes with a large privacy protection range and privacy protection modes with a small privacy protection range.

[0102] S200: Based on the voltage value, control the flow of electronic ink between multiple ink filling layers to put the security protection components in different privacy modes; the display brightness of the electronic device screen is different in different privacy modes.

[0103] Specifically, the electronic device can control the input of a corresponding voltage value to the security protection component based on the voltage value, thereby controlling the flow of electronic ink between multiple ink filling layers, and enabling the security protection component to switch from the current privacy mode to different privacy modes. Optionally, at the same time, the electronic ink can be arranged (i.e. flowed) into at least one ink filling layer; the privacy modes corresponding to the arrangement of electronic ink in different ink filling layers are different.

[0104] In this embodiment, the display brightness of the electronic device's screen varies depending on the privacy protection component's state. Higher display brightness corresponds to lower power consumption, while lower display brightness results in higher power consumption.

[0105] The technical solution in this application embodiment, during the use of the electronic device, can respond to the privacy mode switching command of the security protection component in the display panel, dynamically control the flow of electronic ink in the security protection component between multiple ink filling layers in the security protection component, so that the security protection component is in different privacy modes at different times; this method can flexibly switch different privacy modes of the security protection component according to the application scenario of the electronic device. Since the display brightness of the electronic device screen is different in different privacy modes, this avoids the problems of the display brightness being constantly maintained at a low level, the touch recognition function of the electronic device screen being insufficiently sensitive at low display brightness, and the health hazards to the user's eyes at low display brightness. Therefore, during the use of the electronic device, the display brightness of the electronic device screen can be adjusted by flexibly switching different privacy modes of the security protection component, thereby improving the sensitivity of the touch recognition function of the electronic device screen, reducing the health hazards to the user's eyes and the power consumption of the electronic device, improving the performance of the electronic device, enhancing the user experience, and further increasing the widespread usability of the electronic device.

[0106] The process of controlling the flow of electronic ink between multiple ink-filling layers based on voltage values ​​is described below. In one embodiment, the multiple ink-filling layers in the security protection component include multiple different electrode layers, and the different privacy modes include multiple different privacy-prevention modes; the steps in S200 above may include:

[0107] Based on the voltage value, at least one of the multiple different electrode layers is controlled to reach the voltage value in order to control the flow of electronic ink into at least one layer; when the electronic ink flows to different electrode layers, the security protection component is in a different privacy mode.

[0108] The multiple ink-filling layers in the security protection component may include multiple different electrode layers, and each electrode layer may be arranged in parallel and perpendicular to the light-emitting layer of the display screen; the privacy protection range of the multiple privacy protection modes is different, and the privacy protection angle corresponding to the different privacy protection ranges is greater than 0.

[0109] It should be noted that the aforementioned security protection component has multiple different privacy protection modes, and these different privacy protection modes include multiple different privacy protection levels. In this embodiment, the privacy protection mode of the security protection component is different when electronic ink is arranged in different electrode layers. Specifically, when the security protection component is in the privacy protection mode with the minimum privacy protection range, the electronic ink flows to one corresponding electrode layer (i.e., electronic ink is arranged in one corresponding electrode layer), and no electronic ink is arranged in any of the other electrode layers except for this one electrode layer. When the security protection component is in the privacy protection mode with other privacy protection ranges, the electronic ink flows to two corresponding electrode layers (i.e., electronic ink is arranged in two corresponding electrode layers), and no electronic ink is arranged in any of the other electrode layers except for these two electrode layers.

[0110] In the embodiments of this application, the privacy mode of the minimum privacy range of the security protection component corresponds to one electrode layer, and the privacy mode of the other privacy ranges of the security protection component corresponds to two electrode layers.

[0111] At any given time, the electronic device can control at least one of the multiple different electrode layers to reach a voltage value based on the voltage value, so as to control the flow of electronic ink into at least one electrode layer.

[0112] It should be noted that the voltage value of the safety protection component may include the sub-voltage values ​​that need to be input to each electrode layer in the safety protection component during the use of the electronic device. In this embodiment, the sub-voltage value of at least one electrode layer can be a positive voltage value, while the sub-voltage values ​​of other electrode layers can be 0 or negative voltage values. In practical applications, if the sub-voltage value of an electrode layer is positive, the electrode layer can absorb electronic ink, and the electronic ink can flow into the electrode layer; if the sub-voltage value of an electrode layer is 0 or negative, the electrode layer does not absorb electronic ink, and the electronic ink can flow entirely into the other electrode layers.

[0113] Among them, when the security protection component is in different privacy protection modes, the voltage values ​​input to different electrode layers can be different; when the security protection component switches from one privacy protection mode to another privacy protection mode, that is, the electronic ink flows from at least one electrode layer corresponding to one privacy protection mode to at least one electrode layer corresponding to another privacy protection mode.

[0114] In one embodiment, multiple different electrode layers include a first electrode layer and a second electrode layer, and different privacy modes include a first privacy mode and a second privacy mode; when electronic ink flows to different electrode layers, the security protection component is in a different privacy mode, including at least one of the following: when electronic ink flows into the first electrode layer, the security protection component is in a first privacy mode; or, when electronic ink flows into the second electrode layer, the security protection component is in a second privacy mode; wherein, both the first electrode layer and the second electrode layer are perpendicular to the light-emitting layer of the display screen, the dimensions of the first electrode layer and the second electrode layer of the display panel are different in the vertical direction of the light-emitting layer of the display panel, and the privacy range of the first privacy mode is smaller than the privacy range of the second privacy mode.

[0115] In this embodiment of the application, multiple different electrode layers include a first electrode layer and a second electrode layer; correspondingly, the above-mentioned security protection component can be in two different privacy protection modes, namely a first privacy protection mode and a second privacy protection mode; the privacy protection range of the first privacy protection mode and the second privacy protection mode is different.

[0116] In practical applications, the first electrode layer and the second electrode layer are arranged in parallel, and both the first electrode layer and the second electrode layer are perpendicular to the light-emitting layer of the display screen. This design allows the security protection component to be in a first privacy mode when electronic ink is arranged in the first electrode layer, by blocking the light emitted by the light-emitting layer through the first electrode layer. Alternatively, when electronic ink is arranged in the second electrode layer, the light emitted by the light-emitting layer is blocked through the second electrode layer, thereby allowing the security protection component to be in a second privacy mode.

[0117] Optionally, the dimensions of the first electrode layer and the second electrode layer of the display panel are different in the vertical direction of the light-emitting layer of the display panel. That is, the dimensions (i.e., height) of the first electrode layer are different from the dimensions of the second electrode layer. In this embodiment, the example is that the dimensions of the first electrode layer are smaller than those of the second electrode layer. It should be noted that because the first electrode layer is smaller, the area of ​​light blocking when electronic ink is arranged in the first electrode layer is smaller; because the second electrode layer is larger, the area of ​​light blocking when electronic ink is arranged in the second electrode layer is larger. Naturally, the privacy protection range of the first privacy protection mode is smaller than that of the second privacy protection mode.

[0118] The technical solution in this application embodiment controls at least one of the multiple different electrode layers in the security protection component to reach a voltage value based on the voltage value, so as to control the electronic ink to flow into at least one layer. When the electronic ink flows to different electrode layers in the security protection component, the security protection component is in different privacy modes. During the use of the electronic device, the above method can dynamically control the flow of electronic ink in the security protection component between different electrode layers in the security protection component according to the application scenario of the electronic device, so as to flexibly switch the security protection component in different privacy modes, thereby flexibly adjusting the display brightness of the electronic device screen, which can reduce the power consumption of the electronic device to a certain extent and improve the performance of the electronic device.

[0119] The following describes another process for controlling the flow of electronic ink between multiple ink-filling layers based on the voltage value. In one embodiment, the multiple ink-filling layers include a stationary layer, and the steps in S200 described above may include:

[0120] Adjust the current voltage value of the security protection component to the specified voltage value to control all electronic ink flow into the static layer; when the electronic ink flows into the static layer, the security protection component is in the non-peeping mode.

[0121] In the embodiments of this application, the above-mentioned plurality of ink filling layers may include a stationary layer; the stationary layer is used for dynamically arranging electronic ink, that is, the electronic ink can flow into the stationary layer for arrangement, and can also flow into at least one electrode layer (not in the stationary layer) for arrangement.

[0122] Specifically, the electronic device can adjust the current voltage value of the safety protection component to a voltage value, that is, reduce the current voltage value of the safety protection component to that voltage value, so as to control all the electronic ink to flow into the settling layer.

[0123] It should be noted that the voltage value of the safety protection component may include the sub-voltage values ​​that need to be input to each electrode layer in the safety protection component during the use of the electronic device; in this embodiment, the sub-voltage value of each electrode layer can be 0 or a negative voltage value. Optionally, if the sub-voltage value of the electrode layer is 0 or a negative voltage value, the electrode layer does not adsorb electronic ink, and the electronic ink can flow entirely to the settling layer.

[0124] In practical applications, the stationary layer and each electrode layer are vertically connected, and the stationary layer is located on the side of the encapsulation layer furthest from the substrate. Therefore, even after electronic ink is arranged within the stationary layer, it will not block the light emitted by the light-emitting layer. When the electronic ink flows into the stationary layer, the security protection component is in a privacy-free mode. Optionally, the privacy-free mode can also be understood as a privacy-free mode where the privacy angle of the privacy range is 0.

[0125] The technical solution in this application embodiment adjusts the current voltage value of the security protection component to a voltage value that controls all electronic ink to flow into the static layer of the security protection component, so that the security protection component is in a non-peeping mode. The above method can dynamically control the security protection component to switch between different peeping modes and non-peeping modes. After the security protection component switches to the non-peeping mode, the display brightness of the electronic device screen will increase compared to before. This can not only reduce the degree of health hazards to the user's eyes caused by using electronic devices, but also reduce the power consumption of electronic devices to a certain extent. Furthermore, on the basis of increased display brightness, the sensitivity of the touch recognition function of the display screen can also be improved, thereby improving the performance of electronic devices during use, enhancing the user experience, and further increasing the widespread usability of electronic devices.

[0126] In one embodiment, the privacy mode switching command carries a privacy flag; before performing the step of obtaining the voltage value required for the security protection component in S100 above, such as Figure 6 As shown, the above method may further include the following steps:

[0127] S110. Determine the corresponding privacy mode based on the privacy label. The corresponding privacy mode can be a different level of privacy mode or no privacy mode.

[0128] In practical applications, there is a one-to-one correspondence between different privacy protection symbols and different privacy protection modes. Optionally, the aforementioned privacy protection symbols can be privacy protection angles corresponding to the privacy protection range.

[0129] Specifically, the electronic device can respond to the privacy mode switching command of the security protection component, and then determine the privacy mode corresponding to the privacy mode switching command based on the one-to-one correspondence between different privacy icons and different privacy modes and the privacy icon carried in the privacy mode switching command.

[0130] S120. According to the corresponding privacy mode, obtain the voltage value that the security protection component needs to input when the security protection component is in the corresponding privacy mode.

[0131] In one implementation, the electronic device can pre-train an algorithm model, and then input the privacy mode corresponding to the privacy mode switching command into a voltage value acquisition model. The voltage value acquisition model outputs the voltage value that the security protection component needs to input when it is in the corresponding privacy mode. Optionally, the voltage value acquisition model can be composed of at least one combination of convolutional neural network model, fully connected neural network model, long short-term memory neural network model, and recurrent recurrent neural network model.

[0132] In another implementation, the electronic device can look up the privacy mode corresponding to the privacy mode switching command in the mapping relationship, and then determine the voltage value corresponding to the privacy mode in the mapping relationship as the voltage value that the security protection component needs to input when it is in the corresponding privacy mode. Optionally, the above mapping relationship can include the correspondence between different privacy modes and different voltage values ​​that the security protection component needs to input.

[0133] The technical solution in this application embodiment determines the corresponding privacy mode based on the privacy icon, and obtains the voltage value that the security protection component needs to input when it is in the corresponding privacy mode. This method can obtain the voltage value that the security protection component needs to input when it is in the privacy mode corresponding to the privacy mode in the privacy mode switching instruction based on the privacy icon in the privacy mode switching instruction. On this basis, the security protection component can be directly and quickly controlled to be in different privacy modes, thereby improving the timeliness of adjusting the display brightness of the electronic device screen.

[0134] In one embodiment, this application also provides a display brightness control method, which includes the following steps:

[0135] (1) In response to the privacy mode switching command of the security protection component in the display panel, obtain the voltage value required by the security protection component; the security protection component includes multiple ink filling layers and electronic ink;

[0136] (2) Determine the corresponding privacy mode based on the privacy icon carried in the privacy mode switching command; the corresponding privacy mode is a different privacy mode or no privacy mode;

[0137] (3) According to the corresponding privacy mode, obtain the voltage value that the security protection component needs to input when the security protection component is in the corresponding privacy mode.

[0138] (4) Based on the voltage value, control the electronic ink to flow between multiple ink filling layers so that the security protection components are in different privacy modes; the display brightness of the display screen is different in different privacy modes; the multiple ink filling layers include multiple different electrode layers and a stationary layer;

[0139] The steps in step (4) above can be implemented in two ways:

[0140] The different privacy modes mentioned above include multiple privacy levels; the first method may include:

[0141] (41) Based on the voltage value, control at least one of the multiple different electrode layers to reach the voltage value so as to control the electronic ink to flow into at least one layer; when the electronic ink flows to different electrode layers, the security protection component is in a different privacy mode accordingly;

[0142] The system comprises multiple different electrode layers, including a first electrode layer and a second electrode layer, and different privacy modes, including a first privacy mode and a second privacy mode. When electronic ink flows to different electrode layers, the security protection component operates in different privacy modes, including at least one of the following:

[0143] When the electronic ink flows into the first electrode layer, the security protection component is in the first privacy mode, or when the electronic ink flows into the second electrode layer, the security protection component is in the second privacy mode; both the first electrode layer and the second electrode layer are perpendicular to the light-emitting layer of the display screen, the size of the first electrode layer is smaller than the size of the second electrode layer, and the privacy range of the first privacy mode is smaller than the privacy range of the second privacy mode.

[0144] The different privacy modes mentioned above include no privacy mode, and the second method can include:

[0145] (42) Adjust the current voltage value of the security protection component to the voltage value to control all the electronic ink to flow into the stationary layer; when the electronic ink flows into the stationary layer, the security protection component is in the non-peeping mode.
