Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

Fig. 1 is a schematic structural diagram of an LCD display module, and as shown in fig. 1, the LCD display module may include: the array comprises a backlight source, a lower polarizer, an array glass substrate, a liquid crystal layer, a color filter, an upper polarizer and other hierarchical structures; here, red (R), green (G), blue (B), and other sub-pixels are formed on the color filter. The adjacent red, green, blue and other sub-pixels can form a pixel, and the light transmission condition corresponding to each sub-pixel is controlled by adjusting the voltage of the liquid crystal layer, so that each pixel presents corresponding color, and various display contents such as characters, pictures and the like presented on the LCD display module are finally formed by a plurality of pixels.

It can be seen that a user sees the display content from a display component of the electronic device, which in fact may be understood as the user seeing a combination of several pixels present on the display component. Of course, the above is only illustrated by the LCD display module, and actually, various types of display components such as OLED and the like all use the similar "pixel" combination principle to realize content display, and the details are not repeated here.

Therefore, the "wide viewing angle" in the related art described in the background section can be understood as: when a user views a display component of the electronic device at a large angle, the user can still see pixels (which constitute display content) presented on the display component, which ensures that multiple users can respectively view the display content of the electronic device at different angles, and the viewing effect is not affected by the angle change.

However, although the "wide viewing angle" optimizes the display and sharing effects of the electronic device on the display content, it means that the display content on the electronic device of each user is more easily viewed by other users, thereby increasing the risk of peeping and leaking the private content.

Therefore, the present disclosure reduces the risk of private content being peeked through limiting the viewing angle of the pixels on the display assembly; the following detailed description is made with reference to the accompanying drawings.

Fig. 2 is a flow chart illustrating a display method according to an exemplary embodiment, as shown in fig. 2, for use in an electronic device having a parallax barrier layer disposed in front of a display component of the electronic device, the method may include the steps of:

in step 202A, the display mode of the electronic device is determined.

In this embodiment, the electronic device may include any type of device including a display screen, such as a mobile phone, a tablet, a PC, and the like, and the disclosure is not limited thereto.

In an embodiment, the electronic device may predefine a plurality of display modes, such as a private display mode in the present disclosure, and other types of non-private display modes, so that by detecting the display mode in which the electronic device is located, the manipulation intention of the user on the electronic device may be determined; when it is detected that the electronic device is in the private display mode, it may be determined that the user wishes to control the shielding degree of the corresponding display content by adjusting the light transmittance of the content shielding area. The electronic equipment can enable a user to execute mode switching operation based on a predefined mode switching page through providing the mode switching page; alternatively, the user may also trigger an analog or physical button on the electronic device to implement the mode switching operation, which is not limited by this disclosure.

In another embodiment, the electronic device can also perform automatic detection of the display content of the display component and configure itself to the private display mode when the display content contains predefined private content, without the user manually performing the configuration operation of the display mode. Actually, a certain degree of use obstacles, such as limited viewing angle, may be brought to the user in the private display mode, so that it is difficult for the user to use the private display mode for a long time in a daily situation; meanwhile, when the user identifies the private content in the display content, a certain amount of time and energy are consumed, so that the user can hardly identify all the display content in the using process, the privacy of the display content is easily ignored, the parallax barrier layer is abandoned, and even the private content is easily peeped by other users. Therefore, the electronic equipment actively identifies the private content in the display content, and further automatically switches to the private display mode when the private content is identified, so that the user operation can be greatly simplified, the private content can be ensured to be displayed only in the private display mode, and the protection degree of the private content is greatly improved.

In step 202B, identity information of an operator of the electronic device is verified.

In this embodiment, the configuration operation of the display mode of the electronic device and the verification operation of the identity information of the operator are independent of each other, and there is no fixed precedence order or dependency relationship, which is not limited by this disclosure. Of course, in order to simplify the user operation or the processing flow, a certain execution relationship may be given between the two, for example:

in one embodiment, the electronic device may automatically initiate authentication of the operator's identity information when the electronic device is configured in the private display mode. Particularly, when the electronic device is automatically configured to be in the private display mode after detecting the private content in the display content, the electronic device is matched with the automatic start of the identity information verification of the operator, so that the private content can be ensured to be checked only by the operator who passes the identity verification, and the private content is prevented from being checked by the operator who does not pass the identity verification, thereby further improving the protection degree of the private information.

In another embodiment, the electronic device may initiate authentication of the identity information of the operator upon receiving a display mode configuration instruction for the electronic device, without requiring a user to manually initiate an authentication operation for the identity information. Then, since the display mode configuration instruction is used to instruct the electronic device to be configured in the private display mode, when the identity information of the operator is verified, the electronic device may automatically configure itself in the private display mode. For example, if the electronic device provides a mode configuration page for the display mode to the user, the user only needs to perform configuration operation on the mode configuration page to issue the display mode configuration instruction, and the electronic device automatically completes subsequent mode switching and identity verification operations, thereby facilitating simplification of user operation and reduction of user learning cost.

In this embodiment, the electronic device may obtain the identity characteristic data of the operator, and determine that the identity information of the operator is verified when the identity characteristic data matches the identity characteristic data of a user with a predefined authority. Wherein the identity data may comprise at least one of: the authentication instruction input by the operator (for example, the authentication instruction may contain predefined password information), and the specific biological characteristic information of the operator (for example, at least one of fingerprint, palm print, voice print, human face, iris, etc.).

In step 204, when the electronic device is in a predefined private display mode and the identity information of the operator of the electronic device is verified, the parallax barrier layer is enabled to form a parallax barrier at a preset area.

In this embodiment, the electronic device may enable the parallax barrier layer as a whole, wherein the preset area is a coverage area of the parallax barrier layer; for example, the coverage area may cover the entire display screen of the electronic device, or the coverage area may cover only a portion of the display screen of the electronic device, which is not limited by the present disclosure.

In this embodiment, when the parallax barrier layer includes a plurality of parallax barrier units, if the display content includes predefined private content, the electronic device may use the display area of the private content as the preset area, and enable the parallax barrier unit corresponding to the parallax barrier layer in the preset area alone without enabling the parallax barrier units in other areas.

In step 206, the content display manner of the display element is adjusted to enable the display content at the preset area to be located in a visible area of the display element corresponding to the parallax barrier, wherein the visible area is matched with the dynamic observation area of the operator.

In this embodiment, the electronic device may split the display content at the preset region according to the size of the space between the optical barriers constituting the parallax barrier; wherein the viewable area is formed by a space between adjacent optical barriers; and displaying the split display content in the visual area, so that a user in the visual area can view the split display content.

In this embodiment, the visual area may be determined according to a first structural specification of the parallax barrier, a second structural specification of the display unit, and a relative positional relationship among the parallax barrier, the display unit, and the dynamic observation area of the operator; wherein at least a portion of the viewing area is invisible relative to a location outside of the dynamic viewing area, thereby ensuring that only authorized (i.e., authenticated) operators are properly within the viewing area and clearly view the display covered by the parallax barrier, while preventing other users from peeping at the display.

The electronic equipment can determine a corresponding dynamic observation area by capturing information such as eyeball positions, eye sizes, sight focuses and the like of authorized operators; of course, other ways in the related art can be adopted to calculate the dynamic observation region, which is not limited by the present disclosure.

In this embodiment, when the electronic device has a plurality of operators and at least one of the operators fails to pass the authentication, the electronic device may reduce the legibility of the display content in the preset area, so that only the operator (usually the owner) at a close distance may clearly view the display content, and other users (usually non-owners) at a far distance may not clearly view the display content, so as to improve the privacy of the display content. In fact, even if the distance between the operator with the operation authority and the electronic device is far, which results in that the display content cannot be seen clearly after the identifiability is reduced, the operator can also watch the electronic device by approaching the electronic device or moving the electronic device to the side, and the user without the operation authority cannot easily reduce the distance between the operator and the electronic device, thereby being beneficial to further improving the information privacy and the safety.

Wherein the electronic device can reduce the recognizability of the display content at the preset area by at least one of the following ways: the display brightness at the preset area is reduced, the font size of the characters in the display content is reduced, and an interfering background element is added to the display content, which is not limited by the present disclosure.

According to the embodiment, the parallax barrier layer is arranged in front of the display component of the electronic equipment, and the content display mode of the display component is reasonably adjusted, so that the visual area of the display content can be limited by the parallax barrier layer, the display content cannot be randomly observed, and the privacy of the electronic equipment is improved. Meanwhile, identity authentication is carried out on an operator of the electronic equipment, so that only the operator who passes the identity authentication can adjust the visual area of the display content based on the parallax barrier layer, the controllability of the parallax barrier layer is improved, and the user requirements under different scenes are met.

Furthermore, the visual area of the display content is matched with the dynamic observation area of the operator, so that the display content can track and display the operator, the content viewing requirements of the same operator in different scenes and the requirements and habits of different operators in content viewing are met, the operator does not need to actively adapt to the visual area, the user operation is simplified, and the intelligent display of the electronic equipment is realized. In addition, under the scene that the number of people is large, such as buses, markets, restaurants and the like, the distance between users is small, so that the display content on the electronic equipment can be easily peeped by other users nearby, and the authorized operator can change the visual area of the display content by moving the position of the authorized operator to other users slightly deviating from the user even if the other users are very close to each other by tracking and displaying the authorized operator, so that the authorized operator can normally view the display content and avoid peeping by other users nearby.

The following describes the technical solution of the present disclosure in detail by taking the screen display of the mobile device as an example:

fig. 3 is a flow chart illustrating another display method according to an exemplary embodiment, as shown in fig. 3, for use in an electronic device having a parallax barrier layer disposed in front of a display component of the electronic device, the method may include the steps of:

in step 302, the electronic device receives a display mode configuration instruction, and configures itself to a private display mode according to the display mode configuration instruction.

In an embodiment, the electronic device may show a configuration option for a display mode on a screen (for example, located in a mode configuration page shown by the electronic device), and determine whether a display mode configuration instruction is received according to a trigger of the user on the configuration option, so as to perform a corresponding mode configuration operation.

In another embodiment, a mechanical structure may be mounted on the electronic device, for example, the mechanical structure may be in any form of a key, a toggle switch, or the like, and it may be determined whether a display mode configuration instruction is received according to an adjustment operation of a user on the mechanical structure, so as to execute a corresponding mode configuration operation. For example, when the mechanical structure is adjusted to a preset posture, such as a key is pressed or a toggle switch is dialed to a preset position, it may be determined that a display mode configuration command is received.

In step 304, the electronic device initiates authentication of the identity information of the operator upon determining that the electronic device is in the private display mode.

In this embodiment, when in the private display mode, the electronic device may automatically initiate authentication of the identity information of the operator; the authentication operation may be triggered when the electronic device detects that the non-private display mode is switched to the private display mode, or may be triggered periodically when the electronic device is in the private display mode, which is not limited by the present disclosure.

In this embodiment, the electronic device may adopt any identity authentication means in the related art to authenticate the identity information of the operator, which is not limited by this disclosure. For example, when the electronic device adopts a face or iris verification means, a front camera of the electronic device can be turned on, and the face or iris information acquired by the front camera is used as the face or iris information of the operator, and the process can be performed silently, i.e. the process is invisible to the operator; or, when the electronic device adopts a fingerprint or password input or other verification means, the user can be guided to execute the corresponding fingerprint or password input by displaying the corresponding prompt information on the screen, so that the identity information is verified.

In step 306, when the operator passes the verification of the identity information, the process proceeds to step 308, otherwise, the electronic device displays the display content normally.

In step 308, the electronic device determines a dynamic viewing area of the operator.

In this embodiment, the electronic device may perform image acquisition on the operator through the front camera, and analyze a dynamic observation area of the operator from the acquired image. For example, the electronic device may identify, from the captured image, an eyeball position, an eye size, and a gaze focus of the operator, where the eyeball position is used to determine a relative positional relationship between the eyes of the operator and the electronic device (which may refer to a display element and a parallax barrier layer on the electronic device), the eye size is used to determine a self-specification of the dynamic observation region, and the gaze focus is used to determine a viewing direction of the eyes of the operator, so that the dynamic observation region of the operator may be inferred by combining the relative positional relationship, the self-specification and the viewing direction of the dynamic observation region, and the like.

Of course, other ways for determining the dynamic observation area of the operator exist in the related art, and all the ways can be applied to the technical solution of the present disclosure, and the present disclosure does not limit this.

In step 310, the electronic device enables the parallax barrier layer and adjusts the content display mode of the display component according to the dynamic viewing area of the operator.

In this embodiment, when the operator passes the verification of the identity information, indicating that the operator is the owner (or other authorized user) of the electronic device, the electronic device may enable the parallax barrier layer and adjust the content display manner of the display component, so that the display content on the display component can only be completely viewed by the operator, but is invisible or has no readability for other users, so as to ensure the information privacy of the operator.

For example, as shown in fig. 4, assuming that the operator of the electronic device is located at C1 and another user is located at C2, then the parallax barrier layer is located "in front" of the display assembly, i.e., towards the operator (i.e., above in fig. 4); wherein, several parallax barriers (marked as black areas in the parallax barrier layer in fig. 4) are formed on the parallax barrier layer, and the corresponding pixels on the display assembly (marked as black areas on the display assembly in fig. 4) can only be seen by the user through the gaps between the adjacent parallax barriers. Then, with proper configuration of the parallax barrier layer and proper adjustment of the display content on the display element, as shown in fig. 4, the operator at C1 is just able to see through the gaps between the parallax barriers and see all of the display content on the display element completely, while the user at C2 cannot see or see the corresponding display content completely, so that these display contents are invisible or not readable by the user at C2, thereby ensuring information privacy for the operator.

In the technical solution of the present disclosure, the parallax barrier layer may be implemented in various ways, which is exemplified herein with reference to fig. 5, but the present disclosure does not limit this. As shown in fig. 5, assuming that the display component in the electronic device is an LCD display component, the parallax barrier layer may include: a plurality of display barriers arranged in front of the LCD display assembly (the exit direction of the screen light, i.e. the upper side in fig. 11), wherein each display screen comprises a liquid crystal structure layer and a polarizer which are sequentially overlapped in front of the LCD display assembly, and the polarization direction of the polarizer is different from the polarization direction of the exit light of the LCD display assembly; the liquid crystal structure layer may further include a glass electrode 1, a glass electrode 2, and a layer of liquid crystal therebetween.

Then, when any parallax barrier is enabled, the electronic device may change the rotation direction of the liquid crystal between the glass electrode 1 and the glass electrode 2 by adjusting the voltage value applied to the liquid crystal structure layer in the parallax barrier, that is, the voltage value applied between the glass electrode 1 and the glass electrode 2, so that the liquid crystal may change the polarization direction of the outgoing light of the LCD display module; when the polarization direction of the emergent light is perpendicular to the polarization direction of the polarizer in the parallax barrier, the polarizer can block the emergent light, so that a 'barrier' for the emergent light is formed.

When the electronic device performs overall enabling control on all parallax barriers in the whole parallax barrier layer, all the parallax barriers can be connected through the unified control line, and when the electronic device outputs preset voltage values to all the parallax barriers through the unified control line, all the parallax barriers can be simultaneously enabled and controlled. Of course, the parallax barriers in the parallax barrier layer may be divided into a plurality of groups, each group includes at least one parallax barrier, and each group of parallax barriers may use a separate control line, so that the electronic device may separately enable and control each group of parallax barriers, thereby implementing more refined enabling and controlling, which will be described in detail below with reference to fig. 10.

In the embodiment shown in fig. 4, point C1 is located in the viewable area of the electronic device such that an operator located at this point C1 can view the display on the electronic device in its entirety, while point C2 is located outside the viewable area such that a user located at this point C2 cannot or cannot view the display on the electronic device in its entirety. In an exemplary embodiment, the visible region on the display assembly corresponding to the parallax barrier may be determined according to a first structural specification of the parallax barrier formed by the parallax barrier layer, a second structural specification of the display assembly, and a relative positional relationship between the parallax barrier, the display assembly, and the dynamic viewing region.

For example, fig. 6 is a schematic diagram illustrating a principle of a privacy display according to an exemplary embodiment, and as shown in fig. 6, the first structural specification of the parallax barrier may include: overall specifications of the parallax barrier layers (not shown), individual specifications of each parallax barrier b1, b2, b3, etc., and gap specifications between adjacent parallax barriers b1, b2, b3, etc.; the second structural specification of the display assembly may include: the overall specification of the display module, etc.; the relative positional relationship between the parallax barrier, the display component and the dynamic viewing area may include: the spacing d1 between the parallax barrier layer and the display components, the spacing d2 between the parallax barrier layer and the user's dynamic viewing area, the specification d3 of the dynamic viewing area itself, and the like.

The parallax barrier layer and the display component are physical components on the electronic device, so that after the hardware specification of the electronic device is determined, the first structural specification of the parallax barrier, the second structural specification of the display component, the relative position relationship between the parallax barrier and the display component and the like can be determined; for example, as shown in fig. 6, it may be determined that the interval between the parallax barrier layer and the display component is d1, and it may be determined that the parallax barrier on the parallax barrier layer is at b1, b2, b3, and the like. Based on the dynamic viewing area of the operator determined in step 308, the relative positional relationship among the parallax barrier, the display unit, and the dynamic viewing area can be determined.

For example, as shown in fig. 6, since the parallax barrier layer is located between the dynamic viewing area and the display device, and the parallax barrier is in the shape of a barrier, the viewing areas are formed as a plurality of spaced areas separated from each other, wherein the position of each spaced area can be determined by: a first straight line is formed by a first side end point on the dynamic observation region and a second side end point of any parallax barrier interval (i.e. an interval between adjacent parallax barriers) (for example, in fig. 6, a straight line is formed by a left side end point on the dynamic observation region and a right side end point of an interval corresponding to b1, b 2), a second straight line is formed by a second side end point on the dynamic observation region and a first side end point of any parallax barrier interval (for example, in fig. 6, a straight line is formed by a right side end point on the dynamic observation region and a left side end point of an interval corresponding to b1, b 2), and then the first straight line and the second straight line are respectively in a region between two corresponding points on the display assembly, namely, a visible region corresponding to any parallax barrier interval (for example, in fig. 6, a visible region formed by an interval corresponding to b1, b2 is region a 1).

Then, since the respective visible regions formed on the display module are separated from each other, the display contents at the predetermined region can be split according to the size of the space between the optical barriers constituting the parallax barrier; wherein the viewable area is formed by the spacing between adjacent optical barriers; and then, displaying the split display content in the visible area. As shown in fig. 6, originally continuously displayed display content may be split into regions a1, a2, A3, and other viewable regions to facilitate viewing by a user at the dynamic viewing region, and since at least a portion of the viewable regions is invisible with respect to a position outside the dynamic viewing region, the user outside the dynamic viewing region may be prevented from peeping at the display content.

Take fig. 7A-7B as an example. As shown in fig. 7A, assuming that the display content is a circle, when the user switches the display mode to the private display mode, the parallax barrier layer in the longitudinal direction on the electronic device is enabled, and a plurality of parallax barriers and visible areas separated from each other in the longitudinal direction shown in fig. 7B are formed (fig. 7B is only for illustration and is not limited to specific specifications, proportions, etc.); then, by dividing the circle as the display content into the patterns of the corresponding specifications, it can be displayed in the corresponding visual area.

Because there is a gap between adjacent visual areas, when the display content is displayed in the visual areas, there may be a situation that the display content expands along the arrangement direction of the visual areas (i.e. the left-right direction shown in fig. 7B), which causes the display content to "overflow" the screen area of the electronic device along the arrangement direction, so that the display content that is originally only one screen can be expanded to multiple screens (for example, two screens, i.e. left and right, are included in fig. 7B), so that the user can view all the display content by sliding the page.

Further, the parallax barrier layer may take a variety of configurations based on different display requirements, as will be exemplified below for several cases. In one embodiment, if it is desired to limit the user's viewing range in the left-right direction of the electronic device, as shown in fig. 7B, a parallax barrier in the longitudinal direction may be used to divide the display content in the left-right direction within the viewing area displayed on the display component. In another embodiment, if it is desired to limit the user's visible range in the up-down direction of the electronic device, as shown in fig. 8, a parallax barrier in the lateral direction may be used to divide the display content in the up-down direction within the visible range displayed on the display component. In yet another embodiment, if it is desired to limit the visible range of the user in both the left-right direction and the up-down direction of the electronic device, as shown in fig. 9, a dot-block type parallax barrier may be employed, and the visible range limitation in the left-right direction may be achieved between groups of parallax barriers arranged in the longitudinal direction, i.e., between each column of parallax barriers in fig. 9; and the visible range limitation in the up-down direction can be realized between the parallax barriers arranged in the transverse direction in each group, i.e., between each row of the parallax barriers in fig. 9.

In this embodiment, when the electronic device is in the private display mode and the operator passes the verification of the identity information, the display content on the display component can be tracked and displayed for the operator by enabling the parallax barrier layer and adjusting the content display manner of the display component according to the dynamic observation area of the operator, without the need for the operator to actively adjust the relative position relationship with the electronic device, and the operation complexity of the operator is facilitated to be simplified.

Meanwhile, when the operator does not pass the authentication, for example, the owner (or other authorized user) of the electronic device borrows the electronic device for temporary use by the operator, if the electronic device enables the parallax barrier layer and adjusts the content display mode of the display component according to the dynamic observation area of the operator, the display component of the electronic device loses the characteristic of wide viewing angle, even only the operator can view the display content and the owner cannot view the display content, so that the electronic device is separated from the control of the owner, cannot find the private content contained in the display content in time, and cannot further take back the electronic device in time; in other words, the owner can timely find the private information in the display content by using the wide-view characteristic of the electronic equipment under the condition that the operator does not pass the identity information verification, so that the private management of the electronic equipment is facilitated by timely retrieving the electronic equipment and the like, and the information security of the electronic equipment is improved.

Fig. 10 is a flow chart illustrating yet another display method, as shown in fig. 10, for use in an electronic device having a parallax barrier layer disposed in front of a display component of the electronic device, which may include the steps of:

in step 1002, the electronic device identifies private content in the display content.

In this embodiment, the electronic device may automatically identify private content in the display content according to a default or user-defined identification rule. For example, the identification rule may identify content that meets the following conditions as private content: contain a particular privacy profile, contain a particular type of file, originate from a particular user, etc., and the disclosure is not so limited.

In step 1004, the electronic device configures itself in a private display mode when private content is identified.

In this embodiment, the electronic device can automatically configure to the private display mode after recognizing the private content, without an operator separately performing a configuration operation of the display mode. In fact, it is difficult for an operator to comprehensively check whether display content on an electronic device includes private content, because a lot of time and effort are consumed, the operator often can only find the very obvious private content, and other private content is selected to be ignored, so that the operator cannot timely configure the electronic device in a private display mode under many circumstances, and further cannot control display of the private content by enabling a parallax barrier layer and adjusting a content display mode of a display component, thereby easily causing leakage of the private content; in other words, through the automatic identification of the electronic equipment to the private content, and in combination with the automatic configuration to the private display mode, as long as the above-mentioned identification rule is precisely defined in advance, the electronic equipment can be ensured to timely and accurately identify the private content in the display content, so that the display of the private content is further controlled by enabling the parallax barrier layer and adjusting the content display mode of the display component, thereby greatly improving the protection of the private content and avoiding the private content from being easily leaked.

In step 1006, the electronic device initiates authentication of the identity information of the operator.

When the identity information of the operator is verified in step 1008, the process goes to step 1010; otherwise, the electronic equipment displays the display content normally.

In this embodiment, steps 1006-1008 can refer to steps 304-306 in the embodiment shown in fig. 3, and are not described herein again.

In step 1010, the electronic device determines, according to a display area of the private content on the display assembly, a parallax barrier unit corresponding to the display area.

In an embodiment, a static scheme may be adopted, that is, the private content is fixedly displayed in a preset area of the electronic device, that is, a position of a display area corresponding to the private content on the display assembly is fixed. For example, it is possible to analyze in advance the private content that may be displayed on the electronic device, for example, the private content may include a password input area, a dialog display area, and the like, and directly use the analyzed area as the display area of the private content.

In another embodiment, a dynamic scheme may be employed, i.e., the electronic device may dynamically identify private content within the displayed content and dynamically determine the display area of the private content on the display element. For example, 12 areas including the areas S1 to S12 shown in fig. 11 may be pre-divided on the electronic device, and when the electronic device identifies any private content, for example, the private content is the message content in the message box shown in fig. 11, the electronic device may determine the area where the message box is located and use the area as the display area of the private content, for example, the message boxes in fig. 11 are located in the areas S2 to S3, and the areas S2 to S3 may be used as the display area of the private content.

In step 1012, the electronic device determines a dynamic viewing area for the operator.

In this embodiment, for the determination method of the dynamic observation region, refer to step 308 in the embodiment shown in fig. 3, which is not described herein again.

In step 1014, the electronic device enables the parallax barrier unit and adjusts the content display mode of the display element according to the dynamic viewing area of the operator.

In this embodiment, based on the determined display area of the private content, the electronic device may further determine the parallax barriers in the parallax barrier layer that are disposed at the display area, and perform enabling control on these parallax barriers to achieve reduction of the viewing angle of the private content, thereby ensuring that the private content is only visible to an operator in the visible area.

For the embodiment shown in fig. 11, the parallax barriers in each area may be divided into one group, and a separate control line is used for each group of parallax barriers; then, when the display areas of the private content are determined to be the areas S2 to S3, the electronic device can reduce the viewing angle of the private content without affecting the "wide view" display of the display content in the other areas by enabling the parallax barrier in the areas S2 to S3 and adjusting the content display manner of the display elements for the display content in the areas S2 to S3.

It should be noted that: in the technical scheme of the disclosure, during the process of using the electronic device, an authorized operator may have other unauthorized users nearby, and these unauthorized users may be very close to the authorized operator, so that the display content on the electronic device is easily peeped.

In one case, when the electronic device performs authentication based on a human face, an iris, or the like, a plurality of operators may be detected at the same time; then, when there are a plurality of operators in the electronic device and at least one of the operators fails to pass the authentication, the electronic device may further reduce the recognizability of the display content at the preset area in a case where the viewing angle of the display content is reduced by the parallax barrier at the preset area. For example, the electronic device may employ at least one of the following: the display brightness at the preset area is reduced, the font size of the characters in the display content is reduced, and interfering background elements (including static display elements, dynamic display elements, etc.) are added to the display content, which is not limited by the present disclosure.

By reducing the identifiability of the display content, other unauthorized operators (i.e. unauthorized users) originally close to the authorized operator cannot clearly view the display content, and the authorized operator usually can clearly view the display content because the authorized operator is in the visible area; of course, the reduction of the recognizability may cause that the authorized operator cannot recognize the display content temporarily, but since the authorized operator can easily change the relative position relationship between the authorized operator and the electronic device, the authorized operator can change the relative position relationship, so that the authorized operator can carefully recognize the display content in a closer distance or under other conditions, and the normal viewing of the display content by the authorized operator is not influenced while the information security is improved.

In another case, when the electronic device does not recognize an unauthorized operator, but the authorized operator considers that the unauthorized operator has a possibility of peeping the display content, the authorized operator only needs to slightly move the position of the authorized operator, for example, slightly moving or even slightly rotating the head in a direction away from the unauthorized operator, so that the corresponding dynamic viewing area of the authorized operator changes, the electronic device may perform a follow-up display of the display content based on the change in the dynamic viewing area, thereby changing the visual area of the displayed content, so that the authorized operator can easily and conveniently display the content in the visual area of the electronic equipment without changing the position of the electronic equipment under the condition that the authorized operator slightly moves, the possibility that the display content is peeped can be quickly and effectively avoided, and normal viewing of the display content by an authorized operator cannot be influenced.
