[0047] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0048] The embodiment of the present application provides a display panel, which includes: the safety protection component, the display screen and the control circuit in any of the above embodiments, the display screen includes a packaging layer and a substrate; the safety protection component is located on a side of the packaging layer away from the substrate;

[0049] The control circuit is used to obtain a voltage value required to be input by the security protection component in response to an anti-peeping mode switching instruction of the security protection component; the security protection component includes electronic ink and multiple ink filling layers;

[0050] The security protection component is used to receive a voltage value and control the flow of electronic ink between multiple ink filling layers so that the security protection component is in different anti-peeping modes; the display brightness of the display screen in the display panel is different in different anti-peeping 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 a packaging layer and a substrate. The safety protection component is located on a side of the packaging layer away from the substrate.

[0052] In one embodiment, the display screen further includes a light-emitting layer, the light-emitting layer includes a plurality of light-emitting units, and the safety protection component is disposed around each light-emitting unit.

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

[0054] In practical applications, the control device in the electronic device can receive and respond to the anti-peeping mode switching instruction of the security protection component, obtain the voltage value that the security protection component needs to input, 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 anti-peeping modes.

[0055] Optionally, at the same time, the electronic ink may be arranged into (ie flow into) at least one ink filling layer; different anti-peeping modes may correspond to different ones after the electronic ink is arranged in different ink filling layers.

[0056] In the embodiment of the present application, when the security protection component is in different anti-peeping modes, the display brightness of the display screen is different. The higher the display brightness of the display screen, the lower the power consumption of the electronic device; the lower the display brightness of the display screen, the higher the power consumption of the electronic device.

[0057] In one embodiment, the display panel further comprises: a touch encapsulation layer, a polarizer layer and a cover layer; the touch encapsulation layer, the polarizer layer and the cover layer are sequentially arranged above the safety protection component. Figure 1 Shown are the display screen, safety protection components (first electrode layer, second electrode layer and static layer), touch packaging layer, polarizer layer and cover layer in the display panel; and a setting position relationship diagram among the touch packaging layer, polarizer layer and cover layer.

[0058] In the embodiment of the present application, the touch encapsulation (TOE) layer is used to respond to the touch of a finger on the display screen; the polarizer (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; the cover layer can resist external impact and directly contact the finger.

[0059] In an embodiment of the present application, the control circuit in the display panel can flexibly control and switch different anti-peeping modes of the security protection component according to the actual application scenario. In particular, since the display brightness of the display screen in the display panel is different in different anti-peeping modes, this can avoid the display brightness of the display screen being maintained at a low display brightness for a long time, the touch recognition function of the display screen being not sensitive enough at a low display brightness, and causing certain health hazards to the user's eyes at a low display brightness. Therefore, in the actual application of the display screen, the display brightness of the display screen can be adjusted by flexibly switching different anti-peeping modes of the security protection component, thereby improving the sensitivity of the touch recognition function of the display screen, 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, which can further increase the wide applicability of the display panel.

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

[0061] Among them, at least one ink filling layer among the multiple ink filling layers is used to receive the voltage value required by the security protection component in different anti-peeping modes 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 anti-peeping modes.

[0062] In the embodiment of the present application, the display screen may be an organic light-emitting diode (OLED) type display screen, wherein the components from the bottom to the top of the display screen are a substrate, a base, a driving circuit layer, a light-emitting layer, a conductive layer, and a packaging layer.

[0063] The security protection component may be a privacy film or electronic paper, and the security protection component has a privacy protection function; the security protection component may include electronic ink and a plurality of different ink filling layers, and the ink filling layers may include at least two. Optionally, at the same time, the electronic ink may be arranged in (i.e., flow into) at least one ink filling layer; different privacy protection modes may be different after the electronic ink is arranged in different ink filling layers.

[0064] In the embodiment of the present application, when the security protection component is in different anti-peeping modes, the display brightness of the display screen is different. The higher the display brightness of the display screen, the lower the power consumption of the electronic device; the lower the display brightness of the display screen, the higher the power consumption of the electronic device.

[0065] It should be noted here that a control circuit can be set in the electronic device. The control circuit can be set on the original PCB board set in the electronic device, or it can be set on a brand new PCB board and then built into the electronic device. At the same time, the above control circuit is connected to the metal wire of the security protection component to achieve communication connection. Specifically, the control circuit can respond to the anti-peeping mode switching instruction of the security protection component in the display panel, obtain the voltage value required to be input by the security protection component, and then input the corresponding voltage value to the security protection component.

[0066] In practical applications, the composition structure of the above-mentioned security protection component may include, from bottom to top, the first PE protective film layer, the PET layer, the anti-peeping structure layer, the PET layer, the AG hardened layer and the second PE protective film layer. Among them, the first PE protective film layer and the second PE protective film layer are both the outermost structures of the security protection component, and have good waterproofness and sealing properties; the PET layer has excellent physical and mechanical properties, excellent electrical insulation, creep resistance, fatigue resistance, friction resistance, and good dimensional stability; the AG hardened layer has high wear resistance, high light transmittance, high sensitivity, and is not easy to leave fingerprints, dust, oil stains, etc., and is easy to clean, which can effectively eliminate strong glare, improve the outdoor use of electronic equipment, and have special optical properties to prevent ultraviolet and infrared penetration; the anti-peeping structure layer can be understood as a blind, which is used to change the wide viewing angle of the display screen into a narrow viewing angle by controlling the light angle, and is achieved through a parallel grating structure (blind), so that light at a certain angle cannot pass through the display screen and reflect back to the display screen, so as to achieve the effect of an anti-peeping display screen and reduce the display angle of the display screen.

[0067] Simply put, the above-mentioned anti-peeping structure layer can limit the visible area of ​​the display screen to effectively prevent the leakage of information output on the display screen. For example, if the visible area of ​​the display screen is 60 (that is, users at any position within 30 degrees to the left and right of the main user can see the information output on the display screen), then the range outside 30 degrees to the left and right of the main user is the anti-peeping range, and users at any position within this range can only see the display screen as a dark patch, that is, other areas outside the visible area are all anti-peeping areas, which can effectively prevent information leakage.

[0068] In an embodiment of the present application, the security protection component includes: electronic ink and multiple ink filling layers; each ink filling layer is connected and arranged, 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 anti-peeping modes to control the electronic ink to flow between the multiple ink filling layers, and the display brightness of the electronic device display screen is different in different anti-peeping modes; this embodiment can flexibly switch different anti-peeping modes of the security protection component according to the application scenario, wherein, since the display brightness of the electronic device display screen is different in different anti-peeping modes, it can avoid the problem that the display brightness of the display screen is maintained at a low display brightness for a long time, the touch recognition function of the electronic device display screen is not sensitive enough at a low display brightness, and the low display brightness causes certain health hazards to the user's eyes. Therefore, in the actual application process, the display brightness of the electronic device display screen can be adjusted by flexibly switching different anti-peeping modes of the security protection component, thereby improving the sensitivity of the touch recognition function of the electronic device display screen, the health hazards caused to the user's eyes, and the power consumption of the electronic device, so as to improve the performance of the electronic device, and this design method can greatly improve the wide applicability of the security protection component.

[0069] In one embodiment, different anti-peeping modes include multiple different anti-peeping degree modes; multiple ink filling layers include multiple different electrode layers, and the electrode layers are arranged in parallel; at least one of the electrode layers is used to receive a voltage value to control the electronic ink to flow into at least one layer, so that the security protection component is in different anti-peeping degree modes accordingly.

[0070] Among them, the multiple ink filling layers in the security protection component may include multiple different electrode layers, and the electrode layers can be arranged in parallel and perpendicular to the light-emitting layer of the display screen; the anti-peeping ranges of different anti-peeping modes in the above-mentioned multiple different anti-peeping modes are different, and the anti-peeping angles corresponding to different anti-peeping ranges are all greater than 0.

[0071] It should be noted here that the above-mentioned security protection component has multiple different anti-peeping modes, and different anti-peeping modes include multiple different anti-peeping degree modes; in the embodiment of the present application, when the electronic ink is arranged in different electrode layers, the corresponding anti-peeping degree modes of the security protection component are different, wherein, when the security protection component is in the anti-peeping degree mode with the minimum anti-peeping range, the electronic ink flows to a corresponding electrode layer (that is, the electronic ink is arranged in a corresponding electrode layer), and no electronic ink is arranged in any electrode layer except this electrode layer in all electrode layers; when the security protection component is in the anti-peeping degree mode with other anti-peeping ranges, the electronic ink flows to the corresponding two electrode layers (that is, the electronic ink is arranged in the corresponding two electrode layers), and no electronic ink is arranged in any electrode layer except these two electrode layers in all electrode layers.

[0072] In the embodiment of the present application, the anti-peeping degree mode of the minimum anti-peeping range of the security protection component corresponds to one electrode layer, and the anti-peeping degree modes of other anti-peeping ranges of the security protection component all correspond to two electrode layers.

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

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

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

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

[0077] In actual 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 method can block the light emitted by the light-emitting layer through the first electrode layer when the electronic ink is arranged in the first electrode layer, thereby putting the security protection component in the first anti-peeping mode, or, when the electronic ink is arranged in the second electrode layer, block the light emitted by the light-emitting layer through the second electrode layer, thereby putting the security protection component in the second anti-peeping mode.

[0078] Optionally, the size of the first electrode layer of the display panel and the second electrode layer of the display panel in the vertical direction of the light-emitting layer of the display panel are different, that is, the size (i.e., height) of the first electrode layer is different from the size of the second electrode layer. In the embodiment of the present application, the size of the first electrode layer is smaller than the size of the second electrode layer. It should be noted here that since the size of the first electrode layer is smaller, the range of light blocked when the electronic ink is arranged in the first electrode layer is smaller; since the size of the second electrode layer is larger, the range of light blocked when the electronic ink is arranged in the second electrode layer is larger. Naturally, the anti-peeping range of the first anti-peeping mode is smaller than the anti-peeping range of the second anti-peeping mode.

[0079] Among them, the anti-peeping angle corresponding to the anti-peeping range of the first anti-peeping degree mode can be 20 degrees, 25 degrees, 40 degrees, etc. Correspondingly, the anti-peeping angle corresponding to the anti-peeping range of the second anti-peeping degree mode can be 27 degrees, 35 degrees, 48 ​​degrees, etc. In the embodiment of the present application, the anti-peeping angle corresponding to the anti-peeping range of the first anti-peeping degree mode is equal to 30 degrees, and the anti-peeping angle corresponding to the anti-peeping range of the second anti-peeping degree mode is equal to 60 degrees.

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

[0081] It should be noted here that the second electrode layers are respectively arranged on both sides of the first electrode layer, so that when the electronic ink flows into the second electrode layers, the security protection component can only play an anti-peeping role for users within the anti-peeping range corresponding to the second anti-peeping mode, and will not play an anti-peeping role for users within the anti-peeping range corresponding to the first anti-peeping mode. In this way, the corresponding anti-peeping functions of the security protection component in the first anti-peeping mode and the second anti-peeping mode are independent of each other and are not affected by each other.

[0082] Among them, 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 the corresponding part of the light and cannot be emitted through the electrode layer. At this time, the maximum angle of the light emitted by the light-emitting layer will be reduced. Naturally, the anti-peeping range of the security protection component will become smaller.

[0083] like Figure 2 The figure shows the flow of electronic ink from the safety protection component to the first electrode layer. Figure 2 Each shaded rectangle in the figure represents a light-emitting layer in the display screen. Each light-emitting layer can emit blue light, red light, and yellow light. The arrow line segment indicates the direction of the corresponding light emitted by the light-emitting layer. The range on both sides of the thin arrow line segment is Figure 2 The anti-peeping range of the security protection component in the figure, the range within the thin arrow line segment is the visible range of the security protection component; the four rectangular blocks on both sides of the shaded rectangle represent the same security protection component, and the black solid rectangle represents the first electrode layer in the security protection component, the hollow rectangles on both sides of the first electrode layer represent the second electrode layer, and the horizontal hollow rectangle represents the static layer. Among them, the thick arrow line segment is perpendicular to the light-emitting layer, and the angle between the thin arrow line segment and the thick arrow line segment represents the maximum visible angle (that is, the maximum angle of the light emitted by the light-emitting layer), and all ranges within the maximum visible angle are called the maximum visible range of the security protection component (which can be understood as a cone of the maximum visible angle with the thick arrow line segment and the orthocenter of the light-emitting layer as the origin). If the maximum visible angle is 60 degrees, the anti-peeping range of the security protection component can be all ranges outside the 60-degree cone with the thick arrow line segment and the orthocenter of the light-emitting layer as the origin.

[0084] Figure 3 Shown Figure 2 A diagram showing the flow of electronic ink from the safety protection component to the second electrode layer. Figure 3 The angle between the medium-thin arrow segment and the thick arrow segment represents the maximum viewing angle. Figure 4 Shown Figure 2 A diagram showing the flow of electronic ink from the safety protection component to the stationary layer. Figure 4 All areas above the middle static layer and the luminous layer are within the visible range of the safety protection components.

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

[0086] In an embodiment of the present application, different anti-peeping modes include multiple different anti-peeping degree modes, and the multiple ink filling layers in the security protection component include multiple different electrode layers. The electrode layers are arranged in parallel, and at least one of the electrode layers is used to receive a voltage value to control the flow of electronic ink into at least one layer, so that the security protection component is in different anti-peeping degree modes accordingly. On this basis, the display brightness of the electronic device display 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 method of the security protection component in this embodiment can greatly improve the wide applicability of the security protection component.

[0087] In one embodiment, the multiple ink filling layers in the safety protection component further include a stationary layer, and the stationary layer is vertically connected to each electrode layer.

[0088] In an embodiment of the present application, the above-mentioned multiple ink filling layers may include a static layer; the static layer is used to dynamically arrange the electronic ink, that is, the electronic ink can flow into the static layer for arrangement, and can also flow into at least one electrode layer (not in the static layer) for arrangement.

[0089] In actual applications, the stationary layer and each electrode layer are vertically connected. Therefore, even if the electronic ink is arranged in the stationary layer, the stationary layer will not block the light emitted by the light-emitting layer. When the electronic ink flows into the stationary layer, the safety protection component is in a non-peeping mode. Optionally, the non-peeping mode can also be understood as a peeping mode in which the peeping angle of the peeping range is 0 degrees, that is, a peeping mode in which the angle of the visible area is 90 degrees.

[0090] In an embodiment of the present application, the multiple ink filling layers in the security protection component also include a static layer, which is vertically connected to each electrode layer. This design method can make the electronic ink flow between the static layer and each electrode layer to dynamically control the security protection component to switch between different anti-peeping modes and no anti-peeping mode. When the security protection component is applied to electronic devices, this can not only reduce the degree of health damage to the user's eyes caused by using electronic devices, but also reduce the power consumption of the electronic device to a certain extent. On the basis of increasing the display brightness of the display screen, the sensitivity of the touch recognition function of the display screen can also be improved, thereby improving the performance of the electronic device during the use of the electronic device, improving the user experience, and further increasing the wide applicability of the electronic device. Therefore, this design method of the security protection component in this embodiment can greatly improve the wide applicability of the security protection component.

[0091] In the display field, display devices are widely used in electronic devices for outputting display-related information such as images, videos, and text. In practical applications, electronic devices are usually used in public places, so it is particularly important to protect the information output by the electronic devices. In the related art, a security protection component is mainly set on the display screen of the electronic device to protect the information output by itself. However, in the process of using the security protection component in the related art, the display brightness of the electronic device display screen is low, which makes the power consumption of the electronic device high, thereby causing the problem of low performance of the electronic device. Based on this, an embodiment of the present application provides a display brightness control method, which can avoid the problem that the display brightness of the display screen is always maintained at the lowest display brightness. The display brightness of the electronic device display screen can be flexibly adjusted during the use of the electronic device, thereby reducing the power consumption of the electronic device to a certain extent and improving the performance of the electronic device.

[0092] The display brightness control method provided in the embodiment of the present application can be applied to electronic devices, which can be devices with display functions such as smart phones, smart watches, smart bracelets, tablet computers, laptops, personal computers, and televisions. The specific form of the electronic device is not limited in this embodiment. The specific process of the display brightness control method will be specifically introduced in the following embodiment, and the specific process of the display brightness control method will be introduced with the execution subject being the electronic device.

[0093] like Figure 5 FIG. 1 is a flow chart of a display brightness control method provided in an embodiment of the present application. The method may include the following steps:

[0094] S100, in response to an anti-peeping mode switching instruction of a security protection component in a display panel, obtaining a voltage value to be input by the security protection component, wherein the security protection component includes electronic ink and a plurality of ink filling layers.

[0095] In an embodiment of the present application, the electronic device includes a display panel and a safety protection component, the display panel includes a display screen, 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; the safety protection component can be based on the optical principle of a blind to achieve an anti-peeping function, and the safety protection component can be understood as an anti-peeping film or electronic paper. Among them, the safety protection component has an anti-peeping function; the safety protection component can include electronic ink and multiple different ink filling layers, and the ink filling layer can include at least two. In an embodiment of the present application, the electronic ink can be black particles.

[0096] In actual applications, the electronic device can receive an anti-peeping mode switching instruction of a security protection component attached to the electronic device display screen input by a main user, and can also detect the distance and angle of each user around the main user from the electronic device based on a built-in distance sensor and angle sensor, and then determine whether there is at least one secondary user among the users based on the distance and / or angle of each user from the electronic device. If so, it indicates that the information output by the display screen has protection requirements relative to the secondary users. At this time, the anti-peeping mode switching instruction of the security protection component can be automatically generated based on the angle of each secondary user from the electronic device.

[0097] Optionally, the main user can be understood as the user who directly uses the electronic device; the main user can input the anti-peeping mode switching instruction in the form of voice, gesture, touch screen, button, keyboard, etc. In the process of using the electronic device, the main user can determine whether there is at least one side user among the users according to the distance and / or angle of the users around him from the electronic device. If there is, it indicates that the information output by the display screen has protection requirements relative to the side user. At this time, the anti-peeping range of the security protection component for the side user can be determined according to the angle of each side user from the electronic device, and then the anti-peeping mode switching instruction corresponding to the security protection component is input to the electronic device according to the anti-peeping range.

[0098] The anti-peeping range of the security protection component for the side user may include the anti-peeping angle of the security protection component for the side user, and the anti-peeping angle may be equal to the angle between the side user and the electronic device. Optionally, the angle between the side user and the electronic device may be equal to the angle between the line between the main user and the electronic device and the angle between the electronic device and the side user. It should be noted here that there may be multiple users around the main user, and the multiple users may include at least one side user, and the main user has the purpose of anti-peeping each side user.

[0099] In actual 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, the user can be determined as a bystander; if the distance between the user and the electronic device is greater than the preset distance threshold and the angle between the user and the electronic device is less than the preset angle threshold, the user can be determined as a bystander; if the distance between the user and the electronic device is less than the preset distance threshold and the angle between the user and the electronic device is greater than the preset angle threshold, the user can be determined as a bystander.

[0100] Among them, after the electronic device receives or obtains the anti-peeping mode switching instruction of the security protection component, it can instruct the electronic device to switch from the current anti-peeping mode to another anti-peeping mode; different anti-peeping modes have different anti-peeping ranges. Specifically, the electronic device can respond to the anti-peeping mode switching instruction of the security protection component in the display panel, and first obtain the voltage value required to be input by the security protection component. Optionally, the voltage value required to be input by the above-mentioned security protection component can be a positive voltage value or a negative voltage value.

[0101] It should be noted here that during the use of electronic devices, different anti-peeping 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 requirements for the information output from the display screen; optionally, different anti-peeping modes may include an anti-peeping mode with a large anti-peeping range and an anti-peeping mode with a small anti-peeping range.

[0102] S200. According to the voltage value, control the electronic ink to flow between the multiple ink filling layers so that the security protection component is in different anti-peeping modes; the display brightness of the electronic device display screen is different in different anti-peeping modes.

[0103] Specifically, the electronic device can control the input of a corresponding voltage value to the security protection component according to the voltage value to control the electronic ink to flow between multiple ink filling layers, so that the security protection component switches from the current anti-peeping mode to a different anti-peeping mode. Optionally, at the same time, the electronic ink can be arranged in (i.e., flow into) at least one ink filling layer; different ink filling layers have different corresponding anti-peeping modes after the electronic ink is arranged.

[0104] In the embodiment of the present application, when the security protection component is in different anti-peeping modes, the display brightness of the electronic device display screen is different. The higher the display brightness of the electronic device display screen, the lower the power consumption of the electronic device; the lower the display brightness of the electronic device display screen, the higher the power consumption of the electronic device.

[0105] The technical solution in the embodiment of the present application can dynamically control the electronic ink in the security protection component to flow between multiple ink filling layers in the security protection component in response to the anti-peeping mode switching instruction of the security protection component in the display panel during the use of the electronic device, so that the security protection component is in different anti-peeping modes at different times; the method can flexibly switch different anti-peeping modes of the security protection component according to the application scenario of the electronic device, wherein, since the display brightness of the electronic device display screen is different in different anti-peeping modes, this can avoid the problem that the display brightness of the display screen is always maintained at a low display brightness, the touch recognition function of the electronic device display screen is not sensitive enough at a low display brightness, and the low display brightness causes certain health hazards to the user's eyes. Therefore, in the process of using the electronic device, the display brightness of the electronic device display screen can be adjusted by flexibly switching different anti-peeping modes of the security protection component, thereby improving the sensitivity of the touch recognition function of the electronic device display screen, the health hazards caused 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, and further increasing the wide use of the electronic device.

[0106] The following is a description of a process of controlling the flow of electronic ink between multiple ink filling layers according to the voltage value. In one embodiment, the multiple ink filling layers in the security protection component include multiple different electrode layers, and the different anti-peeping modes include multiple different anti-peeping degree modes; the steps in S200 may include:

[0107] According to the voltage value, at least one of the multiple different electrode layers is controlled to reach the voltage value 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 different anti-peeping modes accordingly.

[0108] Among them, the multiple ink filling layers in the security protection component may include multiple different electrode layers, and the electrode layers can be arranged in parallel and perpendicular to the light-emitting layer of the display screen; the anti-peeping ranges of different anti-peeping modes in the above-mentioned multiple different anti-peeping modes are different, and the anti-peeping angles corresponding to different anti-peeping ranges are all greater than 0.

[0109] It should be noted here that the above-mentioned security protection component has multiple different anti-peeping modes, and different anti-peeping modes include multiple different anti-peeping degree modes; in the embodiment of the present application, when the electronic ink is arranged in different electrode layers, the corresponding anti-peeping degree modes of the security protection component are different, wherein, when the security protection component is in the anti-peeping degree mode with the minimum anti-peeping range, the electronic ink flows to a corresponding electrode layer (that is, the electronic ink is arranged in a corresponding electrode layer), and no electronic ink is arranged in any electrode layer except this electrode layer in all electrode layers; when the security protection component is in the anti-peeping degree mode with other anti-peeping ranges, the electronic ink flows to the corresponding two electrode layers (that is, the electronic ink is arranged in the corresponding two electrode layers), and no electronic ink is arranged in any electrode layer except these two electrode layers in all electrode layers.

[0110] In the embodiment of the present application, the anti-peeping degree mode of the minimum anti-peeping range of the security protection component corresponds to one electrode layer, and the anti-peeping degree modes of other anti-peeping ranges of the security protection component all correspond to two electrode layers.

[0111] Among them, at any time, the electronic device can control at least one electrode layer among multiple different electrode layers to reach a voltage value according to the voltage value, so as to control the electronic ink to flow into the at least one electrode layer.

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

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

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

[0115] In an embodiment of the present application, the 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 anti-peeping modes, namely a first anti-peeping mode and a second anti-peeping mode; the anti-peeping ranges of the first anti-peeping mode and the second anti-peeping mode are different.

[0116] In actual 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 method can block the light emitted by the light-emitting layer through the first electrode layer when the electronic ink is arranged in the first electrode layer, thereby putting the security protection component in the first anti-peeping mode, or, when the electronic ink is arranged in the second electrode layer, block the light emitted by the light-emitting layer through the second electrode layer, thereby putting the security protection component in the second anti-peeping mode.

[0117] Optionally, the first electrode layer and the second electrode layer of the display panel have different sizes in the vertical direction of the light-emitting layer of the display panel, that is, the size (i.e., height) of the first electrode layer is different from the size of the second electrode layer. In the embodiment of the present application, the size of the first electrode layer is smaller than the size of the second electrode layer. It should be noted here that since the size of the first electrode layer is smaller, the range of light blocked when the electronic ink is arranged in the first electrode layer is smaller; since the size of the second electrode layer is larger, the range of light blocked when the electronic ink is arranged in the second electrode layer is larger. Naturally, the anti-peeping range of the first anti-peeping mode is smaller than the anti-peeping range of the second anti-peeping mode.

[0118] The technical solution in the embodiment of the present application controls at least one of the multiple different electrode layers in the security protection component to reach a voltage value according to the voltage value, so as to control the electronic ink to flow into at least one layer, and when the electronic ink flows to different electrode layers in the security protection component, the security protection component is in different anti-peeping modes accordingly; during the use of the electronic device, the above method can dynamically control the electronic ink in the security protection component to flow 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 to different anti-peeping modes, and then flexibly adjust the display brightness of the electronic device display screen, which can reduce the power consumption of the electronic device to a certain extent and improve the performance of the electronic device.

[0119] Another process of controlling the flow of electronic ink between multiple ink filling layers according to the voltage value is described below. In one embodiment, the multiple ink filling layers include a stationary layer, and the steps in S200 may include:

[0120] The current voltage value of the security protection component is adjusted to the voltage value to control the electronic ink to flow completely into the static layer; when the electronic ink flows into the static layer, the security protection component is correspondingly in a non-peeping mode.

[0121] In an embodiment of the present application, the above-mentioned multiple ink filling layers may include a static layer; the static layer is used to dynamically arrange the electronic ink, that is, the electronic ink can flow into the static layer for arrangement, and can also flow into at least one electrode layer (not in the static layer) for arrangement.

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

[0123] It should be noted that the voltage value of the safety protection component may include the sub-voltage value that needs to be input to each electrode layer in the safety protection component during the use of the electronic device; in the embodiment of the present application, the sub-voltage value of each electrode layer may 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 absorb the electronic ink, and the electronic ink can all flow to the static layer.

[0124] In practical applications, the stationary layer is vertically connected to each electrode layer, and the stationary layer is located on the side of the encapsulation layer away from the substrate. Therefore, even if the electronic ink is arranged in the stationary layer, the stationary layer will not block the light emitted by the light-emitting layer. When the electronic ink flows into the stationary layer, the safety protection component is in a non-peeping mode. Optionally, the non-peeping mode can also be understood as a peeping angle mode in which the peeping range is 0.

[0125] The technical solution in the embodiment of the present application adjusts the current voltage value of the security protection component to a voltage value to control the electronic ink to flow completely into the static layer of the security protection component, so that the security protection component is in a non-peeping mode accordingly; the above method can dynamically control the security protection component to switch between different anti-peeping modes and the non-peeping mode. After controlling the security protection component to switch to the non-peeping mode, the display brightness of the electronic device display screen will increase relative to before, which can not only reduce the degree of health damage to the user's eyes caused by using electronic devices, but also reduce the power consumption of the electronic device to a certain extent, and on the basis of increasing the display brightness of the display screen, the sensitivity of the touch recognition function of the display screen can also be improved, thereby improving the performance of the electronic device during the use of the electronic device, improving the user experience, and further increasing the wide applicability of the electronic device.

[0126] In one embodiment, the anti-peeping mode switching instruction carries an anti-peeping identifier; before executing the step of obtaining the voltage value required to be input by the security protection component in the above S100, such as Figure 6 As shown, the above method may further include the following steps:

[0127] S110: Determine a corresponding anti-peeping mode according to the anti-peeping identifier, wherein the corresponding anti-peeping mode is a mode with different degrees of anti-peeping or a mode without anti-peeping.

[0128] In practical applications, there is a one-to-one correspondence between different anti-peeping marks and different anti-peeping modes. Optionally, the anti-peeping mark may be an anti-peeping angle corresponding to the anti-peeping range.

[0129] Specifically, the electronic device can respond to the anti-peeping mode switching instruction of the security protection component, and then determine the anti-peeping mode corresponding to the anti-peeping mode switching instruction based on the one-to-one correspondence between different anti-peeping identifiers and different anti-peeping modes and the anti-peeping identifier carried in the anti-peeping mode switching instruction.

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

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

[0132] In another implementation, the electronic device can search the anti-peeping mode corresponding to the anti-peeping mode switching instruction in the mapping relationship, and then determine the voltage value corresponding to the anti-peeping mode in the mapping relationship as the voltage value that the security protection component needs to input when the security protection component is in the corresponding anti-peeping mode. Optionally, the above mapping relationship may include a correspondence between different anti-peeping modes and different voltage values ​​that the security protection component needs to input.

[0133] The technical solution in the embodiment of the present application determines the corresponding anti-peeping mode according to the anti-peeping identifier, and obtains the voltage value that the security protection component needs to input when the security protection component is in the corresponding anti-peeping mode according to the corresponding anti-peeping mode; the method can obtain the voltage value that the security protection component needs to input when the anti-peeping mode switching instruction corresponds to the anti-peeping mode according to the anti-peeping identifier in the anti-peeping mode switching instruction, and on this basis, the security protection component can be directly and quickly controlled to be in different anti-peeping modes, thereby improving the timeliness of adjusting the display brightness of the electronic device display.

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

[0135] (1) In response to an anti-peeping mode switching instruction of a security protection component in a display panel, obtaining a voltage value required to be input by the security protection component; the security protection component includes a plurality of ink filling layers and electronic ink;

[0136] (2) Determine the corresponding anti-peeping mode according to the anti-peeping identifier carried in the anti-peeping mode switching instruction; the corresponding anti-peeping mode is a mode with different anti-peeping degrees or a mode without anti-peeping;

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

[0138] (4) According to the voltage value, the electronic ink is controlled to flow between the multiple ink filling layers so that the security protection component is in different anti-peeping modes; the display brightness of the display screen is different in different anti-peeping modes; the multiple ink filling layers include multiple different electrode layers and a static layer;

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

[0140] The above-mentioned different privacy protection modes include multiple privacy protection modes with different privacy protection levels; the first mode may include:

[0141] (41) controlling at least one of the plurality of different electrode layers to reach a voltage value according to the voltage value, so as to control the electronic ink to flow into the at least one layer; when the electronic ink flows to different electrode layers, the security protection component is in a correspondingly different anti-peeping mode;

[0142] The plurality of different electrode layers include a first electrode layer and a second electrode layer, and the different privacy protection modes include a first privacy protection mode and a second privacy protection mode; when the electronic ink flows to different electrode layers, the security protection component is in different privacy protection 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 anti-peeping mode, or when the electronic ink flows into the second electrode layer, the security protection component is in the second anti-peeping mode; the first electrode layer and the second electrode layer are both 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 anti-peeping range of the first anti-peeping mode is smaller than the anti-peeping range of the second anti-peeping mode;

[0144] The above different privacy protection modes include no privacy protection mode, and the second mode may include:

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