Detailed Description

Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

Example one

Referring to fig. 1, a flowchart of a display method according to a first embodiment of the present invention is shown, where the method is applied to a mobile terminal, and a pixel unit in a screen of the mobile terminal can emit light rays in at least one direction at the same time, where the method specifically includes the following steps:

step 101, determining at least one display direction according to the eyeball position of the target user.

In order to enable the mobile terminal to display in at least one display direction according to a target user in a targeted manner, that is, actively control the display direction displayed by the mobile terminal according to the target user, the mobile terminal can achieve a better display effect for target users in different display directions, reduce the possibility that non-target users or users not in the display direction see the display content of the mobile terminal, achieve the purpose of displaying in a targeted manner, and improve the safety and privacy of display, the mobile terminal can determine at least one display direction according to the eyeball position of the target user.

The display content, which may include a concrete or abstract image, is composed of a set of light-emitting states of each pixel unit in the screen. The light emission state includes whether or not light is emitted, the color of light emission, the light emission luminance, the light emission direction, and the like.

The pixel unit is the smallest display unit in the screen.

In the embodiment of the invention, the pixel unit in the screen of the mobile terminal can have a plurality of light-emitting directions and can emit light to at least one direction simultaneously.

The target user may include a specific user meeting the preset user characteristics, and the mobile terminal may detect the user and perform identity recognition on the detected user, including determining whether the user characteristics of the user meet the preset user characteristics, and determining the user whose user characteristics meet the preset user characteristics as the target user.

The mobile terminal can acquire the image of the environment through the camera, detect whether the acquired image includes the user or not through technologies such as a face recognition technology and an iris recognition technology, and acquire the user characteristics of the detected user.

The preset user characteristics are used for screening users to determine target users, and the preset user characteristics can be determined in advance by the mobile terminal, for example, the preset user characteristics are obtained by receiving user submission.

For example, the preset user characteristic may include at least one of a fingerprint characteristic, a palm print characteristic, an iris characteristic, a face characteristic, a gender characteristic, and the like, or may include a password, a verification code, and the like.

The eyeball position can comprise the eyeball position of at least one target user, and the mobile terminal can identify the eyeball position of the user through the double cameras.

For example, a schematic view of a scene for identifying the eyeball position of a user by two cameras is shown in FIG. 2, the point A and the point B respectively represent double cameras, the point C represents an eyeball of a user, an included angle between the direction of the point A pointing to the eyeball and a plane where the screen is located is R, the recorded distance between the point C and the plane where the screen is located is h, the distance between the point A and the point C is R, the included angle between the edge of the shooting range of the camera and the plane where the screen is located is a, the distance between the point A and the point B is d, the distances between the point C and the left and right edges of the shooting range of the camera represented by the point A are X2 and X1, the distances between the point C and the left and right edges of the shooting range of the camera represented by the point B are Y1 and Y2, the distance between the point C and the projection distance A on the straight line where the point A and the point B are d1, and the distance between the point B is d 2. Since the values of X1/X2 and Y1/Y2 can be determined by the position of the eyeball in the imaging range of the camera from the camera, and d can be obtained from the storage space of the dual-camera module, according to the relevant parameters of the dual-camera module and the geometrical relationship between the above points, X1+ X2 ═ Y1+ Y2, (X1+ X2)/2+ (Y1+ Y2)/2- (X1+ Y1) ═ d, X1/X2 e, and Y1/Y2 f can be obtained, and the values of X1, X2, Y1, and Y2 can be obtained by solving, wherein X1 ═ f +1 ed/(f-e), and X2 ═ f +1) d/(f-e); and tan (a) ═ h/((X1+ X2)/2) is obtained from the angle a, that is, h ═ tan (a) ((X1+ X2)/2, since X1 and X2 have been calculated in the above, h, that is, the distance of the eyeball from the plane where the screen is located, can be obtained; and from d1 ═ X1+ X2)/2-X1, d2 ═ Y1+ Y2)/2-Y1, where X1, X2, Y1 and Y2 have been calculated above and thus, d1 and d2 are also known; r can be calculated by tan (r) ═ h/d1, so that the angle r between the eyeball and the camera and the distance h between the eyeball and the plane where the screen is located are calculated, and the positioning of the eyeball position is completed.

Since the eyeball position is already determined, the mobile terminal may determine, according to the eyeball position, direction data for a pixel unit through a direction data conversion model established in advance, the direction data being data that explains a display direction of the pixel unit.

The direction data conversion model is used for determining direction data for pixel units according to eyeball positions, and can comprise a first machine learning model or other kinds of mathematical models, and the direction data conversion model can receive input eyeball positions, calculate and output direction data for pixels.

The mobile terminal can acquire a plurality of eyeball positions and direction data aiming at the pixel units in advance, and a mathematical model is established by a modeling method such as a mathematical induction method; or training the first machine learning model by taking a plurality of eyeball positions and direction data aiming at pixel units as first samples so as to obtain the direction data conversion model.

In the embodiment of the present invention, optionally, as can be seen from the foregoing, the eyeball position may include an eyeball position of at least one target user, and therefore, in order to improve flexibility of a display mode of the mobile terminal and improve a display effect, a corresponding target user may be determined according to the eyeball position, and a direction in which the at least one target user is respectively located is determined as a display direction; alternatively, the direction in which one eyeball is present may be determined as one display direction.

In addition, in order to achieve that the mobile terminal can achieve a better display effect for any user in different display directions, the target user may include any user that can be detected by the mobile terminal, that is, the mobile terminal does not perform identity recognition on the user. Accordingly, the mobile terminal may also determine the display direction in other ways. For example, the mobile terminal may provide a display direction setting entry, and receive the submitted display direction through the display direction setting entry; alternatively, the mobile terminal may obtain at least one preset display direction (e.g., set by a manufacturer before leaving a factory) from a local storage; or, a plurality of beacons are arranged in the direction in which the image needs to be displayed in advance, the mobile terminal detects the beacons through components such as a camera or a sensor, and determines the display direction according to the detected beacons, or the mobile terminal detects the environment in which the mobile terminal is located through the camera and determines the direction in which the user is located as the display direction.

Beacons, which are used to indicate the location or direction of the beacon, can emit a specific signal that can be identified by a sensor, such as a radio frequency card. When the mobile terminal detects the beacon, if the beacon is used for explaining the position information of the beacon, the mobile terminal can acquire the position information of the mobile terminal through positioning (including satellite positioning or base station positioning), or locally acquire the position information of the mobile terminal which is stored in advance, and determine the display direction according to the position information of the beacon and the position information of the mobile terminal; if the beacon is used to specify the direction information, the display direction can be determined directly from the direction information.

For example, the mobile terminal determines three display directions, namely, a front direction, a left direction 45 degrees from the front direction, and a right direction 45 degrees from the front direction.

Step 102, controlling the pixel unit to emit light to the at least one display direction, so that the screen displays in the at least one display direction.

Because at least one display direction is determined, the display pixel unit can be controlled to emit light to the at least one display direction, so that the screen of the mobile terminal is controlled to display in the at least one display direction, that is, the display direction of the mobile terminal is actively controlled according to the target user, so that the mobile terminal can achieve a good display effect for target users in different display directions, the possibility that non-target users or users not in the display direction see the display content of the mobile terminal is reduced, the purpose of displaying in a targeted manner is achieved, and the safety and the privacy of display are improved.

The screen of the mobile terminal can be provided with a plurality of pixel units, and the screen of the mobile terminal can be displayed aiming at least one display direction by controlling the light-emitting state of each pixel unit.

The mobile terminal can control at least one area in the screen to display respectively aiming at one display direction, or display aiming at the at least one display direction at the same time.

For the structure of the screen and the corresponding control mode, reference may also be made to the related description in the following, and details are not repeated here.

In the embodiment of the present invention, optionally, as can be seen from the foregoing, in order to accurately display a content that is interested by the user to the user, achieve a purposeful purpose, improve accuracy of displaying an image, may obtain a user attribute of a target user, determine a content type corresponding to the user based on the user attribute, obtain the image according to the content type, and display the image in a display direction for the user.

The user attribute is an attribute for describing the user has, and the user attribute may include at least one of the user characteristics mentioned above, height, weight, age, occupation, purchasing power, and hobbies.

The mobile terminal may obtain the user image or scan the user with the camera to obtain the user attribute, or of course, the mobile terminal may also receive the user attribute submitted by the user.

The content type is used to describe the type of display content displayed to the user, e.g., if the displayed image is an advertisement, the content type may include a shopping orientation; if the displayed image is a movie, the content type may include a movie classification.

Wherein the shopping orientation is used to illustrate items of interest to the user.

The mobile terminal may determine the content type for the user through a second machine learning model (such as a neural network model) according to the obtained user attribute.

The second machine learning model is used for determining the content type aiming at the user according to the user attribute, including accepting the input user attribute, and calculating and outputting the content type aiming at the user. The mobile terminal can acquire a plurality of second training scripts in advance, the second training scripts comprise user attributes and corresponding content types, and the content types are determined through the machine learning model and based on the user attributes through the acquired second training scripts for training.

For example, the mobile terminal is an advertisement panel of a subway entrance, the mobile terminal acquires an image of an environment where the mobile terminal is located, the image is recognized to obtain user clothing of the user a, the clothing comprises black business suits, leather shoes and a briefcase, and the shopping orientation for the user a is determined to be formal business based on the second machine learning model according to the user clothing.

Of course, the mobile terminal may obtain the user event of the user from the data system based on the obtained user attribute, and determine the content model for the user according to the user event.

The data system may comprise a server or a cluster of servers, for example, the data system may comprise an electronic shopping platform.

The user event is used for explaining various activities performed by the user, including event time and event content, for example, the user event can comprise a shopping event and can comprise shopping time and purchased goods.

The mobile terminal may determine a content type for the user through the third machine learning model according to the user event.

The third machine learning model is used for determining the content type aiming at the user according to the user event, and comprises the steps of receiving the input user event, calculating and outputting the content type aiming at the user. The mobile terminal may collect a plurality of third training samples in advance, where the third training samples include a user event and a content type corresponding to the user, and train the content type determined by the third machine learning model according to the user event through the collected third training samples.

For example, the mobile terminal acquires an image of an environment, recognizes the image to obtain a facial image of the user a, acquires 10 sets of children clothes purchased by the user a from a certain shopping platform based on the facial image, and determines that the shopping orientation for the user a is children clothes based on the third machine learning model according to the commodities purchased by the user a.

Example two

Referring to fig. 3, a flowchart of a display method according to a second embodiment of the present invention is shown, where the method is applied in a mobile terminal, and a pixel unit in a screen of the mobile terminal can emit light rays to at least one direction at the same time, where the method specifically includes the following steps:

step 301, the mobile terminal receives a directional display mode starting operation instruction, where the directional display mode starting operation instruction is used to control the mobile terminal to display at least one display direction.

Since the size of the screen of the mobile terminal is usually limited, when displaying in at least one display direction, the display content may be displayed in one display direction through a partial area of the screen, and in practical applications, there may be a display requirement in not every direction in the at least one display direction, for example, there is no user in a certain direction of the screen, and it is needless to say that it is not necessary to display the display content in a certain direction, therefore, in order to improve the flexibility of displaying the display content, and to select a suitable display mode to display the display content according to different display scenes or requirements, and improve the display effect, the mobile terminal may determine to display in a normal mode (i.e. without specifying the display direction) according to an operation instruction of the user, or display in a directional display mode for at least one display direction, that is, if an operation instruction for starting the directional display mode is received, the directional display mode is started according to the following steps, otherwise, the display is carried out according to the normal mode.

If the display mode is the directional display mode, the mobile terminal can control the pixel units in the screen to emit light rays to a single direction, so that only a user in the direction can see the light rays of the pixel, and when the pixel units in different areas in the screen respectively emit light rays to different directions, the user in each direction can only see the light rays emitted by the pixel unit in a certain area, so that the pixel units in a plurality of areas can respectively display different display contents to each area, and display of the display contents to at least one display direction is realized. If the display mode is a normal mode, the mobile terminal may control the pixel units in the screen to scatter light around instead of emitting light in a specific direction, and at this time, users in a larger direction range of the screen (for example, in a range in front of the screen) can all see the light emitted by the pixel units.

The directional display mode starting operation instruction can be triggered by a user through preset operations such as click operation, touch operation or sliding operation.

In addition, in practical application, the mobile terminal may determine whether to start the directional display mode according to a preset display mode selection policy instead of determining whether to start the directional display mode according to whether to receive a directional display mode start operation instruction, and determine whether to display the display content in the normal mode or the directional display mode according to the directional display mode start operation instruction.

The display mode selection policy is used for the mobile terminal to determine a display mode adopted by the display content, and the display mode selection policy may be determined in advance by the mobile terminal, for example, receiving a display mode selection policy submitted by a user.

For example, the display mode selection policy may include: and if the user is detected in at least one display direction of the screen, determining to start the directional display mode if the user is detected, otherwise, not starting the directional display mode, namely displaying the display content through a common mode.

Step 302, the mobile terminal determines a first display direction and a second display direction according to the eyeball position of the target user.

In order to display to target users in two directions simultaneously, achieve the purpose of displaying in a targeted manner, and improve the safety and privacy of display, the mobile terminal can determine the first display direction and the second display direction.

The first display direction and the second display direction may be display directions for different users or orientations, respectively. The mobile terminal can determine the first display direction and the second display direction by the mode of determining at least one display direction.

Step 303, the mobile terminal controls the pixel unit to emit light rays to the first display direction and the second display direction, so that the screen displays in the first display direction and the second display direction.

In order to display for two display directions simultaneously, the mobile terminal may control the pixel units in the screen to emit light to the first display direction and the second display direction.

The first display direction and the second display direction are at least one of the foregoing display directions, and the manner of controlling the pixel unit to emit light to the at least one display direction may be referred to in the foregoing description, which is not repeated herein.

In this embodiment of the application, optionally, different display directions may have different users, that is, different display requirements, in order to accurately meet the display requirements of the different display directions, that is, to display different display contents for users in different display directions, respectively, to achieve the purpose of performing display in a targeted manner, and further improve the safety and privacy of display, the mobile terminal may emit light to the first display mode by controlling the first pixel unit, and emit light to the second display direction by controlling the second pixel unit, so as to display different display contents for the two display directions, respectively.

The first pixel unit and the second pixel unit may be pixel units of two portions in the screen, respectively. The mobile terminal may take the pixel unit of the left half of the screen as a first pixel unit and the pixel unit of the right half of the screen as a second pixel unit; or, the pixel unit group of the upper half part in the screen is taken as a first pixel unit, and the pixel unit of the lower half part in the screen is taken as a second pixel unit; alternatively, the pixel cell group of the even rows (columns) in the screen is taken as the first pixel cell, and the pixel cell of the odd rows (columns) in the screen is taken as the second pixel cell. Of course, in practical applications, the first pixel units and the second pixel units may have other distribution manners.

Because there are usually many pixels in the screen, the arrangement is dense, and the sensitivity of human eyes to images is limited, when the pixel unit group of the even rows (columns) in the screen is used as the first pixel unit, and the pixel unit of the odd rows (columns) in the screen is used as the second pixel unit, for the users in the first display direction and the second display direction, the area of the display content displayed in the screen is the same as the area of the screen, and it is not easy to perceive the partial display effect reduced due to the fewer pixel units used for displaying the display content, that is, the users in the first display direction and the second display direction can experience better display effect, that is, the display effect of the mobile terminal is further improved.

In an embodiment of the present invention, optionally, in order to ensure reliability that the mobile terminal can perform display in at least one display direction, the pixel unit includes at least one polarizer tube, each polarizer tube points to a different direction, and accordingly, the electric field intensity in each polarizer tube in the pixel unit may be controlled, so that the polarizer tube pointing to the at least one display direction transmits light.

Wherein, the device that the polarized light pipe passes through for control light, can include the liquid crystal in this polarized light pipe, when the electric field intensity in this polarized light pipe changes, the printing opacity ability of liquid crystal changes, and is corresponding, also can change through this polarized light pipe light how much, and then can send the light of different intensity.

In addition, regarding the structure of the screen and the corresponding control mode, reference may also be made to the related description in the following, and details are not repeated here.

In this embodiment of the application, optionally, in order to ensure that the same content can be displayed in different display directions, that is, to ensure that the display effect is higher for users in different display directions, and achieve the purpose of performing display in a targeted manner, and further improve the display security and privacy, the pixel unit may be controlled to emit light in the first display direction and the second display direction, that is, to display the same display content in different display directions.

The mobile terminal may control all or a part of the pixel units (such as the first pixel unit or the second pixel unit) in the screen to emit light in the first display direction and the second display direction.

In the embodiment of the invention, firstly, the pixel unit in the screen of the mobile terminal can emit light to at least one direction at the same time, and the mobile terminal can determine at least one display direction according to the eyeball position of the target user and control the pixel unit to display to the at least one display direction, so that the display direction displayed by the mobile terminal can be actively controlled according to the target user, the mobile terminal can achieve better display effect aiming at the target users in different display directions, the possibility that the non-target users or the users not in the display direction see the display content of the mobile terminal is reduced, the purpose of displaying in a targeted manner is achieved, and the display safety and privacy are improved.

Secondly, the mobile terminal can start an operation instruction based on the directional display mode, determine to display the display content through the directional display mode or the common mode, improve the flexibility of the display content, be convenient for select a proper display mode to display the display content according to different display scenes or requirements, and improve the display effect.

Secondly, the mobile terminal can control the first pixel unit to emit light to the first display mode and control the second pixel unit to emit light to the second display direction, so that different display contents can be displayed in the two display directions respectively, and the display safety and privacy are further improved.

In addition, the mobile terminal can control the pixel units to emit light rays to the first display direction and the second display direction, so that the same content can be displayed in different display directions, namely, the display effect for users in different display directions is high, and the display safety and privacy are further improved.

EXAMPLE III

Referring to fig. 4, a flowchart of a display method according to a third embodiment of the present invention is shown, where the method is applied in a mobile terminal, and a pixel unit in a screen of the mobile terminal can emit light rays in at least one direction at the same time, where the method specifically includes the following steps:

in step 401, the mobile terminal determines to start the directional display mode.

In order to improve the flexibility of display, realize the purpose of display with pertinence at the same time, improve security and privacy of the display, the mobile terminal can confirm to display according to the ordinary mode, or according to the directional display mode to display to at least one appointed display direction

The mobile terminal may determine to start the directional display mode when receiving the directional display mode start operation instruction.

In this embodiment of the application, optionally, since a mobile terminal such as a mobile phone generally belongs to a private article, it is necessary to identify a user, and determine that the user is a target user, that is, a valid user of the mobile terminal, so as to avoid problems such as data leakage, so as to avoid that a user other than the valid user of the mobile terminal perceives display content currently displayed by the mobile terminal, improve reliability of displaying only for the target user, improve security and privacy of displaying, verify the user identity of the user through face recognition, determine that the user is the target user, that is, determine to start a directional display mode if the user passes the verification, and perform the step of determining at least one display direction according to an eyeball position of the target user.

The mobile terminal can acquire a facial image of a user through the camera, and then carries out face recognition according to the facial image; or, the mobile terminal may perform face recognition in a scanning manner through a camera.

The camera may be provided in the mobile terminal or connected with the mobile terminal.

The face image includes the face of the user, but of course, other parts of the user may be included in the face image in practical applications.

In the embodiment of the present invention, optionally, in order to further improve the security and privacy of the display, the mobile terminal may periodically (for example, every 10 seconds or other specific time) authenticate the current user.

In the embodiment of the present invention, optionally, in order to ensure that the process of verifying the user identity does not interfere with the process of using the mobile terminal normally by the user, the mobile terminal may control the camera to operate in the background to perform identity authentication on the current user.

After the mobile terminal obtains the face image, user features can be extracted from the face image through technologies such as a face recognition technology or an iris recognition technology, the obtained user features are compared with preset user features, if the extracted user features accord with the preset user features, the corresponding user is determined to be a target user, namely the user identity authentication is passed, and if not, the corresponding user is determined not to be the target user, namely the user identity authentication is failed.

The user may submit a facial image of the user to the mobile terminal in advance (for example, when the mobile terminal is started for the first time), and the mobile terminal acquires the submitted facial image, extracts a user feature from the facial image according to a face recognition technology or an iris recognition technology, and stores the user feature as a preset user feature.

In this embodiment of the present invention, optionally, since the mobile terminal may detect multiple users, the mobile terminal may perform identity authentication on the detected multiple users, if all the users are successfully authenticated, step 402 is executed, and if at least one user that fails to be authenticated exists, the display screen is controlled to be turned off, or in another optional embodiment, the display screen may be controlled to be turned off when all the users fail to be authenticated, otherwise step 402 is executed.

In this embodiment of the present invention, optionally, in order to avoid that a user other than a legitimate user of the mobile terminal perceives some display contents that may relate to privacy displayed by the mobile terminal, thereby further improving the security and privacy of the display, if the content displayed on the screen of the mobile terminal is the preset privacy content, the step of determining at least one display direction according to the eyeball position of the target user may be performed together with the step of determining to start the directional display mode.

The preset privacy content may be determined in advance by the mobile terminal, for example, at least one specific storage location may be specified in advance, and the receiving user stores data to the specific storage location, where the data may be used as the preset privacy content; or, the formulated data may be marked as the preset privacy content in advance according to the privacy marking operation instruction of the user.

The privacy marking operation instruction can be triggered by a user through executing preset operation.

In the embodiment of the present invention, optionally, when displaying 3D (three-dimensional) display content, different content needs to be displayed to different eyeballs of a user to achieve a stereoscopic display effect, so that when determining that the display content is 3D display content, it may be determined to start the directional display mode.

The 3D display content may comprise multimedia content based on 3D technologies such as light, color, or time division, such as 3D movies.

The optical division method, the color division method, or the time division method are all 3D technologies, and certainly, in practical applications, other 3D technologies may also be included, and the purpose of the technology is to display two different images in the same screen, for example, simultaneously display an image with chromatic aberration, or switch and display an image with a difference according to the difference, and the two images are received by eyeballs of a user respectively, so that a 3D viewing effect is obtained.

Of course, in practical applications, it may be determined to start the directional display mode when a user 3D display operation instruction is received.

The 3D display operation instruction can be triggered by a user through executing preset operation.

In practical applications, in order to improve the efficiency of displaying images, the display content may be displayed to all detectable users in the following directions without executing step 401.

The method for displaying in at least one display direction based on the determined target user is described below by taking one target user as an example.

At least one display direction is determined based on the eyeball position of the target user, step 402.

The manner of determining at least one display direction according to the eyeball position of the target user may refer to the related description in the foregoing, and details are not repeated here.

In the embodiment of the present invention, optionally, in order to improve the reliability of displaying only for a target user and improve the safety and privacy of displaying, a first eyeball position and a second eyeball position of the target user may be detected, a direction in which the pixel unit points at the first eyeball position is determined as a first display direction, and a direction in which the pixel unit points at the second eyeball position is determined as a second display direction.

In the embodiment of the present invention, optionally, since the relative position between the user and the screen may be changed, and therefore, the eyeball position of the user may also be changed, so as to track the eyeball of the user, ensure that the user can stably and reliably see the image in the screen, further improve the display effect, and the security and privacy of the display, the mobile terminal may perform step 402 periodically or in real time.

Step 403, the mobile terminal controls the pixel unit to emit light to the at least one display direction, so that the screen displays in the at least one display direction.

In the embodiment of the present invention, optionally, in order to ensure that the same content can be displayed for different display directions, that is, to ensure that the display effect is higher for users in different display directions, and to improve the display security and privacy, the pixel unit may be controlled to emit light in the first display direction and the second display direction.

In the embodiment of the present invention, optionally, different display directions may have different users, that is, different display requirements, and in order to meet the display requirements for the different display directions and improve display security and privacy, the first pixel unit may be controlled to emit light to the first display mode, and the second pixel unit may be controlled to emit light to the second display direction.

In the embodiment of the present invention, optionally, in order to provide a naked-eye 3D visual effect, but not filter color information of a light source, different contents are output to left and right eyes, so that a displayed color is brighter and an effect is more vivid, first display content and second display content of the 3D display content may be acquired, the first display content is displayed in the first display direction based on the first pixel unit, and the second display content is displayed in the second display direction based on the second pixel unit.

The mobile terminal may obtain the 3D display content from a local storage or a server, or the mobile terminal may obtain a multimedia content that needs to be displayed on a screen from a video buffer in a multimedia playing frame, and perform format conversion on the multimedia content, thereby obtaining the 3D display content.

The multimedia playing frame is used for driving components such as a display or a loudspeaker to play according to data which is provided by an upper application program and needs to be played, wherein the data comprises images or sound, and the video buffer area is used for caching or rendering the images to be played in a screen.

In addition, in practical application, since the target user may include a plurality of users, that is, a plurality of users may all pass the authentication, the mobile terminal may thus display images to each target user separately, in the manner described above, e.g., user a and user B both authenticated, the mobile terminal determines that the direction of the first pixel unit pointing to the left eye position of the user a is a first display direction, determines that the direction of the second pixel unit pointing to the right eye position of the user a is a second display direction, determines that the direction of the third pixel unit pointing to the left eye position of the user B is a third display direction, determines that the direction of the fourth pixel unit pointing to the right eye position of the user B is a fourth display direction, thus, the 3D movie is played to the user a through the first display direction and the second display direction, and the 3D movie is played to the user B through the third display direction and the fourth display direction. The first pixel unit, the second pixel unit, the third pixel unit and the fourth pixel unit may be pixel units of an nth column, an N +1 th column, an N +2 th column and an N +3 th column in a screen, respectively, where N is a positive integer greater than or equal to 1.

For example, as shown in fig. 5, in step 501, the face information of the owner or user is entered for subsequent use, including obtaining the face information of the user by taking a picture in all directions and recording feature points; in step 502, in a default situation (i.e., the 3D peep-proof mode is not started), the screen scatters light to the surroundings through the normal mode, and surrounding users can see the content in the screen, as shown in the normal mode in fig. 6; in step 503, when the user starts the non-3D peep-proof mode, the distance between the eyeball and the screen is calculated according to the recognized eyeball position of the user, at this time, the screen light-emitting mode is changed from scattering to linear emission, and there are light-emitting points and the positions of the user eyeballs, and the content for the left and right eyes is the same, at this time, only the current user can see the content in the screen, and when the user eyeballs move, the user eyeballs are tracked, as shown in the non-3D peep-proof mode in fig. 6; in step 504, when the user starts the 3D peep-proof mode, the left-right eye difference output is performed for the output result of the previous step, so as to achieve the 3D effect.

Secondly, the mobile terminal can determine the first display direction and the second display direction according to the eyeball position of the target user, so that the display content can be displayed for the target user according to the eyeball position of the target user, the display reliability only for the target user is improved, and the display safety and privacy are further improved.

In addition, the mobile terminal can verify the identity of the user through face recognition, so that the user is displayed to the target user through the identity recognition, the reliability of displaying only the target user is improved, and the safety and the privacy of displaying are further improved.
