Description

Technical Field

Currently, the common writing display devices on the market can meet people's needs in terms of writing response time, screen size, etc. However, with the development of the economy, users' demand for anti-peeping of display devices has gradually emerged. In some usage scenarios, people need the display screen of the display device to be visible only to themselves and have anti-peeping properties.

[0003] At present, common writing display devices all achieve anti-peeping of the display screen by sticking an anti-peep film on the display panel. Although anti-peeping is achieved to a certain extent, it also greatly reduces the user's own experience and is not suitable for anti-peeping settings for larger-sized devices. At the same time, the anti-peeping effect of the anti-peeping film cannot enter the anti-peeping mode on demand according to the different demands of users in different scenarios, because once the anti-peeping film is attached, the display panel will always be in the anti-peeping mode. If you want to exit the anti-peeping mode, you can only tear off the anti-peeping film, and the flexibility of switching between the anti-peeping mode and the non-anti-peeping mode is poor.

[0061] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0062] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0063] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present application, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0064] In order to realize the anti-peeping function of the writing display device, in the related technology, the anti-peeping effect of the display screen is achieved by sticking an anti-peeping film on the display panel of the writing display device. However, on the one hand, the anti-peeping film is not intelligent, and has the same anti-peeping effect for both the user and other people, which will greatly reduce the user's own experience; on the other hand, the principle of the anti-peeping film is to block the light from the side by adding a light-blocking grille, but it will also reduce the light obtained from the front angle, which is not suitable for the anti-peeping setting of larger-sized devices; on the other hand, the anti-peeping film is not intelligent, and its anti-peeping effect cannot turn on the anti-peeping mode according to different scenes or different user needs, and the switching flexibility between the anti-peeping mode and the non-anti-peeping mode is poor; on the other hand, adding an anti-peeping film to the writing display device will increase the production process and cost of the writing display device.

[0065] Based on the above-mentioned defects of realizing the anti-peeping effect of the writing display device through the anti-peeping film, the inventor of the present application creatively proposes to realize the anti-peeping effect of the writing display device without adding the anti-peeping film. Based on this, the present application only realizes the anti-peeping effect through the conventional components of the writing display device, such as the writing pen and the display board. Further, in order to achieve the technical effect that the above-mentioned anti-peeping film cannot achieve, the inventor of the present application creatively proposes that when the display board is in the working mode, it automatically confirms whether the anti-peeping function needs to be turned on based on the position information of the writing pen and the environmental information of the writing display device, and can automatically turn on the anti-peeping function when the preset conditions are met, without the user having to operate other accessories or function options, so that the anti-peeping mode of the display board is controllable. On the one hand, compared with the unintelligent and uncontrollable nature of the anti-peeping film, the anti-peeping method proposed in the present application can determine whether to turn on the anti-peeping according to the position of the writing pen and the environmental information of the writing display device, and has intelligence and controllability; on the other hand, compared with the problem that the anti-peeping film is not suitable for large-size display, the writing display device of the present application does not add any accessories, is not restricted by the use of large size, and has no process increase and cost increase.

[0066] It should be noted that the anti-peeping control method of the present application is implemented by an anti-peeping control system, such as a controller, etc. The anti-peeping control system can be set on a writing display device, such as a display board or a writing pen, and can also be set on an external accessory of the writing display device, without specific limitation. In the present application, the anti-peeping control system is set on a display board as an example to explain the specific implementation method.

[0067] This application first proposes a method for controlling the anti-peeping of a writing display device, such as Figure 1 As shown, Figure 1 It is a flowchart of the first embodiment of the anti-peeping control method for a display device of the present application.

[0068] The writing display device includes a display panel and a writing pen. The anti-peeping control method of this embodiment specifically includes the following steps:

[0069] Step S11: when the display panel is in working mode, obtaining the position information of the writing pen on the display panel.

[0070] Specifically, in an application scenario, the working modes are, for example, the screen is not turned off, the screen is not locked, or the writing state, etc. In these working modes, the anti-peeping control system obtains the position information of the writing pen on the display board. Specifically, the position information can be the projection position information of the writing pen on the display board, or the position information of the tip of the writing pen on the display board, etc.

[0071] Optionally, the display panel may be an LCD screen or an electronic ink (E-ink) screen, without limitation.

[0072] Step S12: Determine the environmental information of the writing display device.

[0073] Specifically, environmental information may include various scene information such as public scenes, meeting scenes, etc. In an application scenario, multiple environmental information scenes can be preset in the anti-peeping control system for users to choose from, or the environmental information of the writing display device can be identified through other methods.

[0074] Step S13: Control the display panel to enter the anti-peeping mode based on the environmental information and the position information.

[0075] Specifically, the anti-peeping control system can determine whether the display panel automatically enters the anti-peeping mode based on environmental information and the position information of the writing pen on the display panel. For example, when the anti-peeping control system detects that the writing pen is in a flat state and the position information of the pen tip remains unchanged within a preset time, and detects that the writing display device is in a public scene, the display panel can be controlled to enter the anti-peeping mode to prevent the display screen of the display panel from being spied on by others.

[0076] In other embodiments, the execution order of step S11 and step S12 may not be limited.

[0077] This embodiment uses the above method to enable the display panel in the working mode to automatically confirm whether the anti-peeping function needs to be turned on based on the position information of the writing pen and the environmental information of the writing display device, and automatically turn on the anti-peeping function when the preset conditions are met, without the need for the user to operate other accessories or function options. Compared with the anti-peeping film, the anti-peeping mode of the display panel of this embodiment is controllable and not permanent. It can enter the anti-peeping mode on demand based on the user's different demands in different scenarios, that is, environmental information. Therefore, it can improve the controllability and flexibility of the anti-peeping control of the writing display device and improve the user experience. Therefore, this embodiment can improve the flexibility, controllability and convenience of the anti-peeping control of the writing display device and improve the user experience.

[0078] Optionally, in this embodiment, step S13 may be performed by Figure 2 The method shown is implemented as, Figure 2 The method shown specifically includes steps S21 to S23:

[0079] Step S21: Determine whether the writing pen is in a flat state based on the position information.

[0080] Specifically, the anti-peeping control system can first determine the central axis of the writing pen based on the position information of the writing pen on the display board, and then determine whether the central axis is parallel to the display surface of the display board. If the central axis is parallel to the display surface of the display board, the anti-peeping control system determines that the writing pen is in a flat state.

[0081] The anti-peeping control system may first obtain the first coordinate information of the pen tip and the second coordinate information of the pen tail, and then obtain the central axis of the writing pen based on the first coordinate information and the second coordinate information.

[0082] This embodiment determines the central axis of the writing pen based on the position information of the writing pen on the display board, and determines whether the writing pen is in a flat state based on the relationship between the central axis and the display surface of the display board. This can improve the accuracy of judging the flat state of the writing pen, improve the flexibility of anti-peep control of the writing display device, and improve the user experience.

[0083] Optionally, the anti-peeping control system can first determine the angle between the writing pen and the display surface of the display panel based on the position information of the writing pen on the display panel, and then compare the angle with a preset angle. If the angle is less than the preset angle, the anti-peeping control system determines that the writing pen is in a flat state.

[0084] Specifically, the anti-peeping control system may set a preset angle, and when the angle between the tip of the writing pen and the display surface of the display panel is smaller than the preset angle, the anti-peeping control system determines that the writing pen is in a flat state.

[0085] Optionally, the preset angle may be a minimum tilt angle detectable by the writing display device. For example, if the minimum tilt angle detectable by the writing display device is 2°, 2° may be set as the preset angle.

[0086] In an application scenario, such as Figure 3 As shown, there is an angle A between the writing pen 260 and the display panel 261, and the angle A is in the range of 0° to 90°. When the angle is 90°, the writing pen 260 is perpendicular to the display panel 261. According to experiments, the minimum tilt angle of the writing pen 260 that can be perceived by the display panel 261 can be determined, that is, when the tilt angle A of the writing pen 260 is less than the minimum tilt angle, the display panel 261 will not be able to detect the exact angle of the angle A or can only read the value of the minimum tilt angle. Therefore, the minimum tilt angle can be used as the preset angle of the display panel 261, that is, when the display panel 261 detects the value of the minimum tilt angle or fails to detect the angle (at this time, the position information of the pen tip can be obtained), it is determined that the writing pen 260 is in a flat state.

[0087] For example, according to experiments, it can be determined that the minimum tilt angle of the writing pen 260 that the display panel 261 can perceive is 2°, and 2° is set as the preset angle. When the tilt angle A of the writing pen 260 is less than 2°, the display panel 261 can only detect and read the angle value of the minimum tilt angle of 2°. Based on this, it can be determined that the writing pen 260 is in a flat state.

[0088] In another application scenario, the preset angle can also be set to a first angle value greater than the above-mentioned minimum tilt angle (for example, if the minimum tilt angle is 2°, 5° can be set as the preset angle). Then, when the angle A between the tip of the writing pen 260 and the display surface of the display panel 261 is less than the first angle value (that is, when the angle A is less than 5°), it is determined that the writing pen 260 is in a flat state.

[0089] This embodiment determines the angle between the writing pen 260 and the display surface of the display panel 261 through the position information of the writing pen 260 on the display panel 261, and based on the relationship between this angle and the preset angle, it can determine whether the writing pen 260 is in a flat state. This can improve the accuracy of judging the flat state of the writing pen 260, improve the flexibility of the anti-peep control of the writing display device, and improve the user experience.

[0090] In one embodiment, when the display panel is in working mode, the anti-peeping control system obtains position information of the writing pen on the display panel, and can determine the central axis of the writing pen based on the position information, and then can determine the angle between the central axis and the display surface of the display panel based on the central axis.

[0091] For the method of obtaining the central axis, please refer to the above embodiment.

[0092] In one embodiment, when the display panel is in working mode, the anti-peeping control system obtains position information of the writing pen on the display panel, and based on this position information, the first coordinate information of the tip of the writing pen and the second coordinate information of the tail of the writing pen can be determined, and based on the first coordinate information and the second coordinate information, the angle between the writing pen and the display surface of the display panel can be determined.

[0093] The above-mentioned coordinate information may include coordinate point information or vector coordinate information, etc.

[0094] If the writing pen is in a flat state, the process proceeds to step S22.

[0095] Step S22: Determine whether the writing pen is in a stationary state based on the position information.

[0096] The anti-peeping control system determines that the writing pen is in a flat state, and then further determines whether the writing pen is in a stationary state based on the position information.

[0097] Specifically, the static state determination method can monitor the pen tip coordinates by algorithm filtering and other methods. If there is a slight fluctuation in the first coordinate information of the pen tip, the slight fluctuation in the first coordinate information of the pen tip is ignored, and the pen tip is still determined to be in a static state. Other determination methods can also be used in other embodiments.

[0098] Specifically, Figure 4 As shown, steps S41 to S42 are used to implement step S22.

[0099] Step S41: based on the position information, obtain the third coordinate information of the pen tip at the previous moment and the fourth coordinate information at the current moment.

[0100] Step S42: If the difference between the third coordinate information and the fourth coordinate information is within the threshold range, it is determined that the writing pen is in a stationary state.

[0101] For example, in one application scenario, when the display panel is in working mode, the anti-peeping control system obtains the position information of the writing pen on the display panel, and can determine whether the writing pen is in a flat state based on this position information. If the anti-peeping control system determines that the writing pen is in a flat state, it further obtains the third coordinate information of the tip of the writing pen at the previous moment and the fourth coordinate information at the current moment based on the position information. If the difference between the third coordinate information and the fourth coordinate information is within the threshold range, it is determined that the writing pen is in a stationary state.

[0102] Because during the use of the writing pen, the movement of the pen tip can better represent the working state of the writing pen than the pen tail, therefore, this embodiment determines that the writing pen is in a stationary state by determining that the pen tip is in a stationary state, which can improve the accuracy of judging the stationary state of the writing pen; further, this embodiment filters the slight fluctuations of the pen tip position in the above manner, which can improve the writing pen's ability to prevent accidental touches, thereby further improving the accuracy of judging the stationary state of the writing pen.

[0103] Optionally, this application can also be Figure 5 The method shown implements step S22, Figure 5 The method shown specifically includes steps S51 to S52:

[0104] Step S51: determining whether the coordinate information of the pen tip of the writing pen floats within a preset value range within a preset time period based on the position information.

[0105] Step S52: If the coordinate information of the pen tip of the writing pen floats within a preset value range within a preset time period, it is determined that the writing pen is in a stationary state.

[0106] For example, in one application scenario, when the display panel is in working mode, the anti-peeping control system obtains the position information of the writing pen on the display panel, and based on this position information, it can determine whether the writing pen is in a flat state. If the writing pen is in a flat state, it can be determined based on the position information whether the coordinate information of the pen tip of the writing pen floats within a preset numerical range within a preset time length. If the coordinate information of the pen tip of the writing pen floats within a preset numerical range within a preset time length, it is determined that the writing pen is in a stationary state.

[0107] Because during the use of the writing pen, the movement of the pen tip can better represent the working state of the writing pen than the pen tail, therefore, this embodiment can improve the accuracy of judging the stationary state of the writing pen by judging that the pen tip is in a stationary state; further, if the pen tip fluctuates slightly within a preset time length, that is, it is within a preset value range, then it is determined that the writing pen is stationary, which can improve the writing pen's ability to prevent accidental touches, thereby further improving the accuracy of judging the stationary state of the writing pen.

[0108] If the writing pen is in the flat state and is in a stationary state, the process proceeds to step S23.

[0109] Step S23: Control the display panel to enter the anti-peeping mode based on the environmental information.

[0110] The anti-peeping control system can determine whether the writing pen is in a flat state based on the position information. If the writing pen is in a flat state and it is further determined that the writing pen is in a stationary state, the display panel is controlled to enter the anti-peeping mode based on the environmental information.

[0111] If the writing pen is in a flat and stationary state, the anti-peeping control system determines that the writing pen is not in use. At this time, the anti-peeping function can be enabled without affecting the user's use of the writing display device. At this time, the anti-peeping control system further determines whether it is really necessary to control the display panel to enter the anti-peeping mode based on environmental information.

[0112] Optionally, in this embodiment, step S23 may be performed by Figure 6 The method shown is implemented, Figure 6 The method shown specifically includes steps S61 to S62:

[0113] Step S61: Determine the scene information of the display panel based on the environmental information.

[0114] Step S62: If the scene information is a conference scene, the display panel is controlled to enter an anti-peeping mode.

[0115] For example, in one application scenario, when the display panel is in working mode, the anti-peeping control system obtains the position information of the writing pen on the display panel; further, the anti-peeping control system determines the environmental information of the writing display device; further, the anti-peeping control system can determine whether the writing pen is in a flat state based on the position information. If the writing pen is in a flat state, and the anti-peeping control system further determines that the writing pen is in a stationary state, then the scene information of the display panel is determined based on the environmental information. If the scene information is a meeting scene, the display panel is controlled to enter the anti-peeping mode.

[0116] The anti-peeping control system determines that the writing display device is in a flat and stationary state based on the writing pen, and further determines that the scene information is a meeting scene before controlling the display panel to enter the anti-peeping mode. Because in the meeting scene, the display screen information of the display panel is relatively important, and there are other people in the meeting scene. Therefore, after determining that the writing pen is in a flat and stationary state and further determining that it is in a meeting scene, the display panel is controlled to enter the anti-peeping mode. This can improve the flexibility, scene applicability and convenience of the anti-peeping control of the writing display device, and improve the user experience.

[0117] Optionally, in this embodiment, step S23 can also be performed by Figure 7 The method shown is implemented, Figure 7The method shown specifically includes steps S71 to S73:

[0118] Step S71: Determine the scene information of the display panel based on the environmental information.

[0119] The specific implementation of step S71 can refer to step S61 and will not be repeated here.

[0120] Step S72: If the scene information includes a public scene, the encryption instructions of the display panel are monitored.

[0121] Step S73: In response to the encryption instruction, control the display panel to enter the anti-peeping mode.

[0122] For example, in one application scenario, when the display board is in working mode, the position information of the writing pen on the display board is obtained; further, the environmental information of the writing display device is determined; further, based on the position information, it can be determined whether the writing pen is in a flat state; if the writing pen is in a flat state, and it is further determined that the writing pen is in a stationary state, then the scene information of the display board is determined based on the environmental information; if the scene information includes a public scene, the encryption instructions of the display board are monitored, and the display panel is controlled to enter the anti-peeping mode in response to the encryption instructions. This enables the writing display device to further monitor the encryption instructions when it is necessary to further refer to the scene information as a public scene based on the fact that the writing pen is in a flat state and in a stationary state. Only when the encryption instructions are detected is the display panel controlled to enter the anti-peeping mode. This can improve the flexibility, scene applicability and convenience of the anti-peeping control of the writing display device, and improve the user experience.

[0123] It should be noted that the implementation method of step S23 may include one or more of the above methods at the same time. For example, when the writing display device is in a flat and stationary state based on the writing pen, and further refers to the scene information that it is a conference scene, the display panel is controlled to enter the anti-peeping mode. Alternatively, when the writing display device is in a flat and stationary state based on the writing pen, and further refers to the scene information that it is a public scene, the display panel is controlled to enter the anti-peeping mode in response to an encryption instruction. The two methods do not conflict.

[0124] Optionally, step S13 can also be performed by Figure 8 The method shown is implemented, Figure 8 The method shown specifically includes steps S81 to S82:

[0125] Step S81: Determine whether the writing pen is in a stationary state based on the position information.

[0126] Specifically, the specific implementation of step S81 can refer to the above Figure 4 , Figure 5The embodiment implements determining whether the writing pen is in a stationary state based on the position information, which will not be described in detail here.

[0127] Step S82: If the writing pen is in a stationary state, the display panel is controlled to enter an anti-peeping mode based on environmental information.

[0128] Specifically, the specific implementation of step S82 can refer to the above Figure 6 , Figure 7 The embodiment realizes controlling the display panel to enter the anti-peeping mode based on environmental information, which will not be described in detail here.

[0129] The setting of step S81 to step S82 can determine whether the writing pen is in a stationary state through position information. If so, the display panel is controlled to enter the anti-peeping mode based on the environmental information. Therefore, through this method, the display panel automatically confirms whether the anti-peeping function needs to be turned on based on the stationary state of the writing pen and the environmental information of the writing display device, and can automatically turn on the anti-peeping function when the preset conditions are met. The user does not need to operate other accessories or function options. When the writing pen is in a stationary state, the display panel is controlled to enter the anti-peeping mode based on the environmental information. It can respond to the user's usage scenarios more intelligently. For example, when the writing pen is in a stationary state, it is usually when the user does not need to use the writing pen. Therefore, this method can improve the flexibility and convenience of the anti-peeping control of the writing display device and improve the user's usage experience.

[0130] Optionally, step S13 can also be performed by Fig. 9 The method shown is implemented, Fig. 9 The method shown specifically includes steps S91 to S93:

[0131] Step S91: Determine whether the projection of the writing pen on the display panel is located in the display area of ​​the display panel based on the position information.

[0132] Optionally, it can be determined based on the position information that the projection of the tip of the writing pen on the display panel and the projection of the tail of the writing pen on the display panel are located in the display area of ​​the display panel, and then it is determined that the writing pen is located in the display area of ​​the display panel.

[0133] For example, in one application scenario, when the display panel is in working mode, the position information of the writing pen on the display panel is obtained, and based on the specific position information of the writing pen on the display panel, it can be determined that the projection of the tip of the writing pen on the display panel and the projection of the tail of the writing pen on the display panel are both located in the display area of ​​the display panel. In this case, it can be determined that the writing pen is located in the display area of ​​the display panel, which can improve the accuracy of the writing display device's judgment on whether the writing pen is located in the display area of ​​the display panel, thereby improving the accuracy of turning on the anti-peep mode.

[0134] Optionally, it can also be determined based on the position information that the projection of the tip of the writing pen on the display panel is located in the display area and the projection of the tail of the pen on the display panel is located in the non-display area of ​​the display panel, thereby determining that the writing pen is located in the display area of ​​the display panel.

[0135] For example, in an application scenario, when the display panel is in working mode, the position information of the writing pen on the display panel is obtained, and based on the specific position information of the writing pen on the display panel, it can be determined that the projection of the writing pen tip on the display panel and the projection of the pen tail on the display panel are located in the non-display area of ​​the display panel, and based on this, it can be determined that the writing pen is located in the display area of ​​the display panel. For example, when the writing pen tip is on the display panel, but the projection of the writing pen tail on the display panel is located in the non-display area of ​​the display panel, it can still be determined that the writing pen is located in the display area of ​​the display panel.

[0136] Based on step S92: if the projection of the writing pen on the display panel is located in the display area, it is determined based on the position information whether the writing pen is in a flat state.

[0137] This embodiment first determines whether the writing pen is in the display area, and then determines the horizontal state of the writing pen, which can avoid the writing pen being in other areas causing the determination of the writing pen state.

[0138] The specific implementation of step S92 can refer to the method of determining whether the writing pen is in a flat state based on the position information in step S21, which will not be repeated here.

[0139] Step S93: If the writing pen is in a flat state, the display panel is controlled to enter an anti-peeping mode based on environmental information.

[0140] For details on the implementation of step S93, please refer to the above Figure 6 , Figure 7 The embodiment realizes controlling the display panel to enter the anti-peeping mode based on environmental information, which will not be described in detail here.

[0141] Optionally, it is also possible to determine whether the projection of the writing pen on the display panel is located in the display area of ​​the display panel based on the position information; if the projection of the writing pen on the display panel is located in the display area, it is determined whether the writing pen is in a stationary state based on the position information; if it is in a stationary state, the display panel is controlled to enter an anti-peeping mode based on environmental information.

[0142] The method for determining the static state can be found in Figure 4 , Figure 5 For example, please refer to the above Figure 6 , Figure 7 The embodiment realizes controlling the display panel to enter the anti-peeping mode based on environmental information, which will not be described in detail here.

[0143] Optionally, in this embodiment, controlling the display panel to enter the anti-peeping mode may be achieved by controlling the display panel to render an anti-peeping effect on the current display interface based on environmental information.

[0144] Specifically, the display panel can be controlled to render an anti-peeping effect on the current display interface to implement the anti-peeping mode. This method is convenient and fast, and can improve the flexibility of turning on the anti-peeping mode. In another embodiment, the anti-peeping effect can be rendered only on the creative interface in the current display interface, which is not specifically limited.

[0145] Optionally, in the present embodiment, the anti-peeping effect of rendering the current display interface based on the environmental information controlling the display panel can be achieved by performing Gaussian blur processing, translucent processing, blinds processing or horizontal mirroring processing on the current display interface based on the environmental information controlling the display panel so that the current display interface displays the corresponding target rendering effect; or it can be achieved by performing screen saver processing on the current display interface based on the environmental information controlling the display panel.

[0146] Specifically, you can choose any one of the processing methods to control the display panel to render an anti-peeping effect on the current display interface, or you can render different anti-peeping effects on the current display interface according to different environmental information. For example, in a public scene, you can control the display panel to perform screen saver processing on the current display interface; or, multiple processing methods can also be set as user-selectable to improve user experience; or, you can choose any one of the processing methods to render an anti-peeping effect on the current display interface, or you can use multiple processing methods to render the anti-peeping effect on the current display interface in different areas. For example, you can control the display panel to perform Gaussian blur processing on a part of the current display interface and perform translucent processing on another part of the interface.

[0147] Specifically, taking note-taking applications as an example, Gaussian blur processing refers to automatically performing Gaussian blur processing on the content created by the user in the display interface, while the UI elements (such as toolbar buttons) remain unchanged. For details, please refer to Figure 10 to Figure 11 , Fig.10 This is a schematic diagram of the display panel before the anti-peeping mode of this application is activated. Fig.11 It is a display schematic diagram of the display panel of the present application in the Gaussian blur processing anti-peeping mode.

[0148] Specifically, taking note-taking applications as an example, semi-transparency processing refers to automatically performing semi-transparency processing on the content created by the user in the display interface, such as increasing the transparency from 0% to 50%, or 78%, or 96%, etc. The specific transparency value can be set by the user. For details, please refer to Fig.12 , Fig.12 It is a display schematic diagram of the display panel of the present application in a semi-transparent anti-peeping mode.

[0149] Specifically, taking note-taking applications as an example, the blinds processing refers to the automatic blinds effect processing of the user-created content in the display interface. Specifically, the page will generate countless parallel thin stripes. The height of the thin stripes can be adjusted, such as 11px or 12px, etc. The spacing of the thin stripes is the same as the height. The thin stripes cover the content created by the user to achieve an anti-peeping effect. For details, please refer to Fig.13 , Fig.13 It is a display schematic diagram of the display panel of the present application in the blinds processing anti-peeping mode.

[0150] Specifically, taking note-taking applications as an example, horizontal mirroring means automatically flipping the content created by the user in the display interface horizontally, so that others cannot easily read it and achieve an anti-peeping effect. Fig.14 , Fig.14 It is a display schematic diagram of the display panel of the present application in the horizontal mirror processing anti-peep mode.

[0151] Specifically, taking note applications as an example, screen saver processing means covering the entire page with a screen saver to achieve an anti-peeping effect. Fig.15 , Fig.15 It is a display schematic diagram of the display panel of the present application in the screen saver processing anti-peep mode.

[0152] In other embodiments, for different application software in the writing display device, the anti-peeping mode may be to perform anti-peeping processing on the entire page.

[0153] In other embodiments, for different application software in the writing display device, the user can customize whether the anti-peeping mode requires the entire page to be anti-peeping processed or only the creative area in the page to be processed.

[0154] Optionally, the display panel is controlled based on the environmental information to render the anti-peeping effect on the current display interface. Fig.16 Similarly, step S23 can be implemented by Fig.16 The method shown is implemented as follows, Fig.16 The method shown specifically includes step S161 and step S163:

[0155] Step S161: Determine the scene information of the display panel based on the environmental information.

[0156] The specific implementation of step S161 can refer to step S61, which will not be repeated here.

[0157] Step S162: Obtain a target rendering effect corresponding to the scene information.

[0158] Step S163: Control the display panel to render the current display interface based on the target rendering effect.

[0159] For example, in an application scenario, when the display panel is in working mode, the position information of the writing pen on the display panel is obtained; further, the environmental information of the writing display device is determined; further, based on the environmental information and the position information, the display panel is controlled to enter the anti-peeping mode (the specific implementation method can refer to the above method), wherein the specific implementation of the anti-peeping mode can first obtain the target rendering effect corresponding to the scene information, and then control the display panel to render the current display interface based on the target rendering effect, that is, control the display panel to enter the anti-peeping mode. For example, the target rendering effect corresponding to the public scene can be set to screen saver processing, then when the environmental information is a public scene, the corresponding target rendering effect (i.e., screen saver processing) is obtained, and then the display panel is controlled to render the current display interface through the screen saver processing.

[0160] The settings of step S161 and step S163 can control the display panel to enter different target rendering effects based on different scene information, that is, enter different forms of anti-peeping modes, which can improve the scene applicability of the anti-peeping control method and improve the user experience.

[0161] Optionally, the screen saver processing of the current display interface by controlling the display panel based on the environmental information can be specifically performed by Fig.17 Similarly, step S23 can be implemented by Fig.17 The method shown is implemented as follows, Fig.17 The method shown specifically includes step S171 and step S174:

[0162] Step S171: Determine the projection area of ​​the writing pen on the display area of ​​the display panel based on the position information.

[0163] For example, in one application scenario, based on the position information, the projection area of ​​the writing pen on the display panel can be determined by determining the projection of the pen tip on the display panel and / or the projection of the pen tail on the display panel; the position area of ​​the writing pen can also be obtained through the coordinates of the pen tip, the orientation of the pen tip, and the length of the writing pen that comes standard with the product.

[0164] Step S172: Determine the scene information of the display panel based on the environmental information.

[0165] The specific implementation of step S172 can refer to step S61 and will not be repeated here.

[0166] Step S173: Obtain a target rendering effect corresponding to the scene information.

[0167] The specific implementation of step S173 can refer to step S162 and will not be repeated here.

[0168] Step S174: Displaying a ripple pattern in an area adjacent to the projection area.

[0169] Specifically, the ripple pattern can be a dynamic diffusion effect, for details, please refer to Figure 18 to Figure 19 , Fig.18 This is a display schematic diagram of the display panel of the present application in the corrugated anti-peeping mode; Fig.19 This is another display schematic diagram of the display panel of the present application in the corrugated anti-peep mode.

[0170] Optionally, the ripple diffusion direction can be set to diffuse outwards with the area where the writing pen is located as the diffusion center.

[0171] Step S171 and step S174 achieve a screen saver effect by displaying a ripple pattern in an area adjacent to the projection area, allowing the user to more intuitively feel the effect that "the position of the pen can be sensed by the writing display device", thereby increasing the user's favorability towards the anti-peeping mode and improving the user's usage experience.

[0172] In one embodiment, the user can freely preset the anti-peeping effect of rendering the current display interface in the anti-peeping mode. For example, the user presets Gaussian blur processing for the current display interface in the anti-peeping mode; for another example, the user presets semi-transparent processing for the current display interface in the anti-peeping mode.

[0173] The choice of multiple interface anti-peeping rendering methods can provide users with rich and diverse anti-peeping effects, improve the flexibility and controllability of anti-peeping control methods, and improve the user experience.

[0174] Optionally, the anti-peeping control method provided in this embodiment is not limited to the size of the writing display device. For example, it can be applied to common 6-inch to 13.3-inch writing display devices on the market, such as 9.7-inch, 10.2-inch, 8-inch and other sizes.

[0175] In other embodiments, similar improvements may be made to the anti-peeping control method for the writing display device, and the details will not be repeated here.

[0176] The present application further proposes a method for controlling a writing display device from peeping, such as Fig. 20 As shown, Fig. 20 1 is a flow chart of the second embodiment of the anti-peeping control method for a writing display device of the present application. The writing display device of the present embodiment includes a display board and a writing pen, and the anti-peeping control method of the present embodiment specifically includes the following steps:

[0177] Step S201: when the display panel is in working mode, obtaining position information of the writing pen on the display panel.

[0178] Please refer to step S11 for the specific implementation, which will not be described in detail here.

[0179] Step S202: Determine the environmental information of the writing display device.

[0180] Please refer to step S12 for the specific implementation, which will not be described in detail here.

[0181] Step S203: Determine whether the writing pen is in a stationary state based on the position information.

[0182] Please refer to the above Figure 4 , Figure 5 The embodiment implements determining whether the writing pen is in a stationary state based on the position information, which will not be described in detail here.

[0183] If the writing pen is in a stationary state, the process proceeds to step S204: determining the scene information of the display panel based on the environmental information.

[0184] Specifically, the specific implementation of step S204 can refer to step S61, which will not be repeated here.

[0185] Step S205: If the scene information includes a public scene, the display panel is controlled to enter an anti-peeping mode.

[0186] The settings of steps S201 to S205 can enable the writing display device to control the display panel to enter the anti-peeping mode only when the writing pen is in a stationary state and further refers to the scene information that it is a public scene. This can improve the flexibility, scene applicability and convenience of the anti-peeping control of the writing display device, and improve the user experience.

[0187] In other embodiments, similar improvements may be made to the anti-peeping control method for the writing display device, and the details will not be repeated here.

[0188] The present application further proposes a method for controlling a writing display device from peeping, such as Fig.21 As shown, Fig.21 1 is a flow chart of the third embodiment of the anti-peeping control method for a writing display device of the present application. The writing display device of this embodiment includes a display board and a writing pen, and the anti-peeping control method of this embodiment specifically includes the following steps:

[0189] Step S211: When the display panel is in working mode, whether an anti-peeping instruction is detected.

[0190] Specifically, in an application scenario, in a working mode such as a screen-on state, a screen-unlocked state, or a writing state, the writing display device monitors whether an anti-peeping instruction is detected during use.

[0191] Optionally, in step S211, the anti-peeping instruction includes but is not limited to an anti-peeping button instruction, an anti-peeping gesture instruction or an anti-peeping timing instruction.

[0192] Specifically, the anti-peeping button instruction can be to click the anti-peeping button on the display panel (the button position and clicking method are not limited); the anti-peeping gesture instruction can be obtained through the sensor of the writing display device or other methods, and the gesture is not limited; the anti-peeping timing instruction can be to maintain the first posture of the writing pen for a preset time.

[0193] If the anti-peeping instruction is detected, the process proceeds to step S212: controlling the display panel to enter the anti-peeping mode.

[0194] For example, the display panel may respond to an anti-peeping button command to control the display panel to enter the anti-peeping mode; for another example, the display panel may respond to an anti-peeping gesture command to control the display panel to enter the anti-peeping mode; for another example, the display panel may respond to an anti-peeping timing command to control the display panel to enter the anti-peeping mode.

[0195] In other embodiments, the specific number and sequence of anti-peeping instructions are not limited. Specifically, it can be set that two or more of the different anti-peeping instructions such as anti-peeping button instructions, anti-peeping gesture instructions, and anti-peeping timing instructions appear at the same time to meet the triggering condition, that is, trigger the display panel to enter the anti-peeping mode. For example, the display panel can respond to the anti-peeping gesture instruction and the anti-peeping timing instruction to control the display panel to enter the anti-peeping mode.

[0196] If no anti-peeping instruction is detected, the process proceeds to step S213: when the display panel is in working mode, obtaining the position information of the writing pen on the display panel.

[0197] The specific implementation of step S213 can refer to step S11 and will not be repeated here.

[0198] Step S214: Determine the environmental information of the writing display device.

[0199] The specific implementation of step S214 can refer to step S12 and will not be repeated here.

[0200] Step S215: Control the display panel to enter the anti-peeping mode based on the environmental information and the position information.

[0201] The specific implementation of step S215 can refer to step S13 and will not be repeated here.

[0202] The settings of step S211 to step S215 can control the display panel to enter the anti-peeping mode through the anti-peeping instruction. In the absence of the anti-peeping instruction, the display panel can be controlled to enter the anti-peeping mode by referring to the environmental information and position information. This can improve the judgment accuracy of the anti-peeping control method, reduce the risk of misjudgment, and improve the user experience.

[0203] In other embodiments, similar improvements may be made to the anti-peeping control method for the writing display device, and the details will not be repeated here.

[0204] The present application further proposes a method for controlling a writing display device from peeping, such as Fig. 22 As shown, Fig. 22 1 is a flowchart of a fourth embodiment of the anti-peeping control method for a writing display device of the present application. The writing display device of this embodiment includes a display board and a writing pen, and the anti-peeping control method of this embodiment specifically includes the following steps:

[0205] Step S221: when the display panel is in working mode, obtain the position information of the writing pen on the display panel.

[0206] The specific implementation of step S221 can refer to step S11 and will not be repeated here.

[0207] Step S222: Determine the environmental information of the writing display device.

[0208] The specific implementation of step S222 can refer to step S12 and will not be repeated here.

[0209] Step S223: Acquire the gesture instruction executed by the user on the display panel.

[0210] Specifically, the gesture instruction can be obtained through a sensor of the writing display device or other methods, and is not limited to gestures.

[0211] Step S224: Control the display panel to enter the anti-peeping mode based on the gesture command, environmental information, and position information.

[0212] Furthermore, the display panel can be controlled to enter the anti-peeping mode based on gesture instructions, environmental information, and position information. For example, in one application scenario, when the display panel is in working mode, the position information of the writing pen on the display panel is obtained; further, the environmental information of the writing display device is determined; further, the gesture instructions executed by the user on the display panel are obtained, and then the display panel is controlled to enter the anti-peeping mode based on the gesture instructions, environmental information, and position information. This can improve the accuracy of judging whether to enter the anti-peeping mode.

[0213] Optionally, in this embodiment, step S224 may be performed by Fig.23 The method shown is implemented, Fig.23 The method shown specifically includes steps S231 to S235:

[0214] Step S231: Determine the scene information of the display panel based on the environmental information.

[0215] Specifically, the specific implementation of step S231 can refer to step S61, which will not be repeated here.

[0216] Step S232: If the scene information is preset scene information, determine whether the projection of the writing pen on the display panel is located in the display area of ​​the display panel based on the position information.

[0217] Step S233: Determine whether the writing pen is in a flat state based on the position information.

[0218] The specific implementation of step S233 can refer to the method of determining whether the writing pen is in a flat state based on the position information in step S21, which will not be repeated here.

[0219] It should be noted that there is no restriction on the order of step S233, step S231 and step S232. For example, the scene information can be determined first (i.e., executing step S231), and then whether the writing pen is in a flat state can be determined based on the position information. For another example, step S231 and step S232 can be executed at the same time as step S233.

[0220] Step S234: In response to the projection of the writing pen on the display panel being located in the display area and determining that the writing pen is in a flat state, parsing the gesture instruction.

[0221] Step S235: In response to the gesture instruction being an anti-peeping gesture instruction, controlling the display panel to enter an anti-peeping mode.

[0222] The setting of steps S231 to S235 allows the writing display device to refer to whether the writing pen is in a flat state and whether the projection of the writing pen on the display panel is located in the display area of ​​the display panel and the gesture command only when the preset scene information is met, and control the display panel to enter the anti-peeping mode based on this, which can improve the flexibility and convenience of the anti-peeping control method.

[0223] It should be noted that in other embodiments, there is no restriction on the order of determining whether the writing pen is in a flat state and whether the projection of the writing pen on the display board is located in the display area of ​​the display board. That is, it is possible to first determine whether the writing pen is in a flat state, and then determine whether the projection of the writing pen on the display board is located in the display area of ​​the display board.

[0224] Optionally, in this embodiment, step S224 can also be performed by Fig.24 The method shown is implemented, Fig.24 The method shown specifically includes steps S241 to S245:

[0225] Step S241: Determine the scene information of the display panel based on the environmental information.

[0226] The specific implementation of step S241 can refer to step S231 and will not be repeated here.

[0227] Step S242: If the scene information is preset scene information, determine whether the projection of the writing pen on the display panel is located in the display area of ​​the display panel based on the position information.

[0228] The specific implementation of step S242 can refer to step S232 and will not be repeated here.

[0229] Step S243: Determine whether the writing pen is in a stationary state based on the position information.

[0230] The specific implementation of step S243 can be found in the above Figure 4 , Figure 5 The embodiment implements determining whether the writing pen is in a stationary state based on the position information, which will not be described in detail here.

[0231] It should be noted that there is no restriction on the order of step 243, step S241 and step S242. For example, the scene information can be determined first (i.e., executing step S241), and then whether the writing pen is in a stationary state can be determined based on the position information. For another example, step S241 and step S242 can be executed while step S243 is also executed at the same time.

[0232] Step S244: In response to the projection of the writing pen on the display panel being located in the display area and determining that the writing pen is in a stationary state, parsing the gesture instruction.

[0233] Step S245: In response to the gesture instruction being an anti-peeping gesture instruction, controlling the display panel to enter an anti-peeping mode.

[0234] The setting of steps S241 to S245 allows the writing display device to refer to whether the writing pen is in a stationary state and whether the projection of the writing pen on the display panel is located in the display area of ​​the display panel and the gesture instruction only when the preset scene information is met, and control the display panel to enter the anti-peeping mode based on this, which can improve the flexibility and convenience of the anti-peeping control method.

[0235] It should be noted that in other embodiments, there is no restriction on the order of determining whether the writing pen is in a stationary state and whether the projection of the writing pen on the display board is located in the display area of ​​the display board. That is, it is possible to first determine whether the writing pen is in a stationary state, and then determine whether the projection of the writing pen on the display board is located in the display area of ​​the display board.

[0236] In other embodiments, similar improvements may be made to the anti-peeping control method for the writing display device, and the details will not be repeated here.

[0237] The present application further proposes a method for controlling a writing display device from peeping, such as Fig.25 As shown, Fig.25 1 is a flowchart of the fifth embodiment of the anti-peeping control method for a writing display device of the present application. The writing display device of this embodiment includes a display board and a writing pen, and the anti-peeping control method of this embodiment specifically includes the following steps:

[0238] Step S251: When the display panel is in working mode, obtain the position information of the writing pen on the display panel.

[0239] The specific implementation method can refer to step S11, which will not be described in detail here.

[0240] Step S252: Determine the environmental information of the writing display device.

[0241] The specific implementation method can refer to step S12, which will not be described in detail here.

[0242] Step S253: Control the display panel to enter the anti-peeping mode based on the environmental information and the position information.

[0243] The specific implementation method can refer to step S13, which will not be described in detail here.

[0244] Step S254: obtaining the dynamic position information of the writing pen on the display panel in the anti-peeping mode.

[0245] Step S255: controlling the display panel to exit the anti-peeping mode based on the dynamic position information of the writing pen in the anti-peeping mode.

[0246] For example, in one application scenario, when the display panel is in anti-peeping mode, the position information of the writing pen can be monitored, that is, the dynamic position information of the writing pen on the display panel can be obtained. When the dynamic position information meets the preset conditions, the display panel is controlled to exit the anti-peeping mode. For example, when the writing pen exits the static state, the display panel can be controlled to exit the anti-peeping mode. This method triggers the action naturally, does not require additional operations (such as clicking buttons, etc.), and is eye-catching, improving the user experience; and this setting method is not limited to the size of the device, and does not require the user to remove certain accessories for the display device (such as tearing off the anti-peeping film, etc.), which is convenient and quick.

[0247] Optionally, the motion state of the pen tip of the writing pen can be determined based on the dynamic position information of the writing pen in the anti-peeping mode; in response to the motion state being a non-stationary state, the display panel is controlled to exit the anti-peeping mode. For example, it can be detected whether the coordinate information of the pen tip of the writing pen changes, or whether the change of the coordinate information of the pen tip of the writing pen exceeds a preset range. If it exceeds the preset range, it can be determined that the motion state of the pen tip of the writing pen is a non-stationary state.

[0248] Because during the use of the writing pen, the movement of the pen tip can better represent the working state of the writing pen than the pen tail, the present embodiment determines the dynamic position information of the writing pen in the anti-peeping mode through the movement state of the writing pen tip, and can control the display panel to exit the anti-peeping mode based on the movement state of the writing pen tip being a non-stationary state, thereby improving the accuracy of judging the non-stationary state of the writing pen.

[0249] In other embodiments, similar improvements may be made to the anti-peeping control method for the writing display device, and the details will not be repeated here.

[0250] The present application further proposes a method for controlling a writing display device from peeping, such as Fig.26 As shown, Fig.26 1 is a flowchart of the sixth embodiment of the anti-peeping control method for a writing display device of the present application. The writing display device of this embodiment includes a display board and a writing pen, and the anti-peeping control method of this embodiment specifically includes the following steps:

[0251] Step S261: When the display panel is in working mode, obtain the position information of the writing pen on the display panel.

[0252] The specific implementation method can refer to step S11, which will not be described in detail here.

[0253] Step S262: Determine the environmental information of the writing display device.

[0254] The specific implementation method can refer to step S12, which will not be described in detail here.

[0255] Step S263: Control the display panel to enter the anti-peeping mode based on the environmental information and the position information.

[0256] The specific implementation method can refer to step S13, which will not be described in detail here.

[0257] Step S264: Obtaining an anti-peeping release instruction in the anti-peeping mode.

[0258] Step S265: controlling the display panel to exit the anti-peeping mode based on the anti-peeping release instruction.

[0259] The anti-peeping mode release command can be used to release the anti-peeping mode of the display panel. For example, the anti-peeping mode release command can be to click any area of ​​the display panel with one or more fingers (the number of clicks is not limited) to exit the anti-peeping mode; or to exit the anti-peeping mode through a fixed gesture, which is not limited.

[0260] The settings of step S261 to step S265 can enable the display panel to automatically exit the anti-peeping mode based on the anti-peeping release instruction, thereby improving the flexibility of the anti-peeping control of the writing display device and improving the user experience.

[0261] In other embodiments, similar improvements may be made to the anti-peeping control method for the writing display device, and the details will not be repeated here.
