DETAILED DESCRIPTION

Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

FIG1 is a schematic diagram of the structure of an LCD display module. As shown in FIG1 , an LCD display module may include: a backlight source, a lower polarizer, an array glass substrate, a liquid crystal layer, a color filter, and an upper polarizer; wherein red (R, red), green (G, green), blue (B, blue) and other sub-pixels are formed on the color filter. Adjacent red, green, blue and other sub-pixels can form a pixel, and the light transmittance corresponding to each sub-pixel is controlled by adjusting the voltage of the liquid crystal layer, so that each pixel presents a corresponding color, and thus a number of pixels ultimately form various display contents such as text and pictures presented on the LCD display module.

It can be seen that when a user sees the displayed content on the display component of an electronic device, it can actually be understood that the user sees a combination of several pixels displayed on the display component. Of course, the above only uses the LCD display module as an example. In fact, various types of display components such as OLED all use similar "pixel" combination principles to realize content display, which will not be repeated here.

Therefore, the "wide viewing angle" in the related technology described in the background technology part can be understood as: when a user views the display component of an electronic device at a large angle, he can still see the pixels displayed on the display component (these pixels constitute the display content). This ensures that multiple users can view the display content of the electronic device at different angles respectively, and the viewing effect will not be affected by changes in angle.

However, although the "wide viewing angle" optimizes the display and sharing effects of electronic devices on displayed content, it also means that the displayed content on each user's electronic device is more easily viewed by other users, thereby increasing the risk of private content being peeped and leaked.

Therefore, the present disclosure reduces the risk of private content being viewed by peeping by limiting the viewing angle of pixels on the display component; this is described in detail below with reference to the accompanying drawings.

FIG. 2 is a flow chart of a display method according to an exemplary embodiment. As shown in FIG. 2 , the method is used in an electronic device, and a parallax barrier layer is provided in front of a display component of the electronic device. The method may include the following steps:

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

In this embodiment, the user can set the display mode of the electronic device according to their own needs. The display mode may include a "private display mode". In this private display mode, the technical solution of the present invention can be used to protect the privacy of the displayed content and prevent it from being peeped by others.

In step 204, when in a predefined private display mode, the parallax barrier layer is enabled to form a parallax barrier located at a preset area; and the content display mode of the display component is adjusted so that the displayed content at the preset area is located within a visible area on the display component corresponding to the parallax barrier.

In this embodiment, the enabling control method of the parallax barrier layer may adopt means in the related art, which will not be described in detail here.

In this embodiment, a parallax barrier layer is provided in front of the display component of the electronic device, and the content display method of the display component is reasonably adjusted, so that the visible range of the displayed content can be limited by the parallax barrier layer, thereby ensuring that the displayed content cannot be viewed at will, which helps to improve the privacy of the electronic device.

For example, as shown in FIG3 , assuming that the owner of the electronic device (or other authorized user) is located at C1 and another user is located at C2, the parallax barrier layer is located in the “front” of the display component, that is, facing the user (i.e., the top in FIG3 ); wherein, a number of parallax barriers are formed on the parallax barrier layer (marked as black areas in the parallax barrier layer in FIG3 ), and the user can only view the corresponding pixels on the display component through the gaps between adjacent parallax barriers (marked as black areas on the display component in FIG3 ). Then, through the reasonable configuration of the parallax barrier layer and the reasonable adjustment of the display content on the display component, as shown in FIG3 , the owner at C1 can just see through the gaps between the parallax barriers and fully view all the display content on the display component, while the user at C2 cannot view or cannot fully view the corresponding display content, so these display contents are invisible or unreadable to the user at C2, thereby ensuring the privacy of the owner's information.

1. Configuration of parallax barrier layer

In the technical solution of the present disclosure, as an exemplary embodiment, the visible area on the display component corresponding to the parallax barrier can be determined based on the first structural specifications of the parallax barrier, the second structural specifications of the display component, and the relative position relationship between the parallax barrier, the display component and the user observation area.

For example, Figure 4 is a schematic diagram of the principle of a private display according to an exemplary embodiment. As shown in Figure 4, the first structural specifications of the parallax barrier may include: the overall specifications of the parallax barrier layer (not shown in the figure), the individual specifications of each parallax barrier b1, b2, b3, etc., and the gap specifications between adjacent parallax barriers b1, b2, b3, etc.; the second structural specifications of the display component may include: the overall specifications of the display component, etc.; the relative position relationship between the parallax barrier, the display component and the user observation area may include: the interval d1 between the parallax barrier layer and the display component, the interval d2 between the parallax barrier layer and the user observation area, the specifications d3 of the user observation area itself, etc.

Then, since the parallax barrier layer and the display component are both physical components on the electronic device, after the hardware specifications of the electronic device are determined, the first structural specifications of the parallax barrier, the second structural specifications of the display component, the relative position relationship between the parallax barrier and the display component, etc. can all be determined; for example, as shown in Figure 4, it can be determined that the interval between the parallax barrier layer and the display component is d1, and it can be determined that the parallax barrier on the parallax barrier layer is at b1, b2, b3, etc.

As for the user observation area, including the specification d3 of the user observation area itself and the interval d2 between the user observation area and the parallax barrier layer, etc., it is related to the actual situation of the user and cannot be determined according to the hardware specifications of the electronic device. Then, based on the method of determining the information related to the user observation area, the present disclosure provides the following display scheme:

1) Static display

As an exemplary embodiment, the user observation area can be a predefined preset area; in other words, it can be assumed in advance that a gap d2 is formed between the user observation area where the user is located and the parallax barrier layer, and the width of the user observation area is d3, that is, d2 and d3 are both predefined values, so that according to the above parameters, the corresponding visible area on the display component can be determined, including areas A1, A2, A3, etc. shown in Figure 4.

For example, as shown in Figure 4, since the parallax barrier layer is located between the user observation area and the display component, and the parallax barrier is in the shape of a fence, the visible area formed is a plurality of separated interval areas, wherein the position of each interval area can be determined in the following manner: a first straight line is formed by a first side endpoint on the user observation area and a second side endpoint of any parallax barrier interval (i.e., the interval between adjacent parallax barriers) (for example, in Figure 4, a straight line formed by the left side endpoint on the user observation area and the right side endpoint of the interval corresponding to b1 and b2), and a second straight line is formed by a second side endpoint on the user observation area and a first side endpoint of any parallax barrier interval (for example, in Figure 4, a straight line formed by the right side endpoint on the user observation area and the left side endpoint of the interval corresponding to b1 and b2). Then, the area between the corresponding two points on the display component of the first straight line and the second straight line is respectively, that is, the visible area corresponding to any parallax barrier interval (for example, in Figure 4, the visible area formed by the interval corresponding to b1 and b2 is area A1).

Then, since the various visible areas formed on the display component are separated from each other, the display content in the preset area can be split according to the spacing size between the optical fences constituting the parallax barrier; wherein the visible area is formed by the spacing between adjacent optical fences; and then, the split display content is displayed in the visible area. As shown in FIG. 4 , the display content originally displayed continuously can be split into visible areas such as areas A1, A2, and A3, so as to facilitate viewing by users in the user observation area, and since at least a portion of the visible area is non-visible relative to a position outside the user observation area, users outside the user observation area can be prevented from peeking at the display content.

Take Figures 5A-5B as an example. As shown in Figure 5A, assuming that the display content is a circle, when the user switches the display mode to the private display mode, the vertical parallax barrier layer on the electronic device is enabled, forming multiple vertical, mutually separated parallax barriers and visible areas as shown in Figure 5B (Figure 5B is only for illustration and does not limit the specific specifications and proportions); then, by cutting the circle as the display content into patterns of corresponding specifications, it can be displayed in the corresponding visible area.

Among them, since there is a gap between adjacent visible areas, when the display content is displayed in the visible area, it may expand along the arrangement direction of the visible area (i.e., the left and right direction shown in Figure 5B), causing the display content to "overflow" the screen area of the electronic device along the arrangement direction. Therefore, the display content that was originally only on one screen can be expanded to multiple screens (for example, the left and right screens in Figure 5B), allowing the user to view all the display content by sliding the page.

2) Dynamic display

As another exemplary embodiment, due to differences in pupil distance, arm length, usage habits, etc. among different users, the predefined user observation area may not be applicable to all users unless all users cooperate with the usage habits of the predefined user observation area, but this will increase the learning cost of the users.

Therefore, in order to reduce the user's learning cost, the present disclosure proposes a dynamic display solution in a private display mode, wherein the electronic device can capture the current user's eye position through a front camera, and then determine the corresponding user observation area based on the eye position.

After the dynamic user observation area is determined, the visible area on the display component can be determined accordingly, so that the display content can be split and displayed. This process is the same as the process of 1) static display and will not be repeated here.

2. The shape of the parallax barrier layer

Based on different display requirements, the parallax barrier layer can be set in a variety of ways, and several cases are illustrated below.

In one embodiment, if you want to limit the user's visual range in the left and right directions of the electronic device, as shown in FIG. 5B , a parallax barrier along the longitudinal direction can be used to divide the display content into the visible area on the display component along the left and right directions.

In another embodiment, if it is desired to limit the user's visual range in the vertical direction of the electronic device, as shown in FIG6 , a parallax barrier along the lateral direction may be used to divide the display content into a visible area on the display component along the vertical direction.

In another embodiment, if it is desired to limit the user's visual range in both the left-right direction and the up-down direction of the electronic device at the same time, as shown in FIG. 7 , a dot-block parallax barrier may be used. Then, between each group of parallax barriers arranged along the vertical direction, that is, between each column of parallax barriers in FIG. 7 , the visual range limitation in the left-right direction may be achieved; and between each group of parallax barriers arranged along the horizontal direction, that is, between each row of parallax barriers in FIG. 7 , the visual range limitation in the up-down direction may be achieved.

3. Specifications of parallax barrier layer

1) Complete Barrier

In an exemplary embodiment, the parallax barrier layer can cover the display area of the display component of the electronic device, that is, the formed parallax barrier can simultaneously act on all display contents of the display component. For example, Figures 5B, 6 and 7 are all embodiments of this case.

2) Regional Barrier

In another exemplary embodiment, the parallax barrier layer may act only on a preset area on the display component; for example, the preset area for realizing private display may be a display area containing private content in the display content, such as a password input area, a dialogue display area, etc.

In one case, a static solution can be adopted, that is, the parallax barrier layer can privately display a predefined preset area, and the position of the preset area cannot be changed. For example, the possible display content can be analyzed in advance, so that the area most likely to display private content is set as the preset area; or, several areas on the display component can be directly set as the above-mentioned preset area, and an agreement can be made with the provider of the display content to ensure that the private content in the display content is displayed in the preset area.

In another case, a dynamic solution can be adopted, that is, the position of the area where the parallax barrier layer can achieve private display is not fixed and can be changed according to actual conditions. For example, as shown in Figure 8, when the user has not enabled the "private mode", the user can see the conversation content on the electronic device at a large angle; when the user enables the "private mode", the electronic device can identify the barrier area containing private content, such as the area where the "conversation content box" shown in Figure 8 is located as the barrier area, then only users in the user observation area can fully view the corresponding conversation content, while other users cannot fully view it, ensuring the privacy of the corresponding content.

4. Mode switching

In one embodiment, the user can manually switch the display mode of the electronic device according to actual needs. For example, when the user manually switches to the private display mode, the electronic device can privately display the display content of the display component through the above embodiment to prevent other users from peeping. When the user manually switches to a non-private display mode, such as a normal display mode, the electronic device can eliminate the parallax barrier, thereby adopting a wide-viewing angle display solution in the related art.

In another embodiment, the electronic device can identify the displayed content, and when the displayed content contains preset private content, the display mode of the electronic device is set to a private display mode, otherwise a non-private display mode can be used. The display content identification process can be implemented using a solution in the related art, which will not be described in detail here.
