The electronic device may be a computer device such as a smart phone, a tablet computer, a palm computer, a notebook computer, or a desktop computer.
Referring to fig. 1, fig. 1 is a schematic flow chart of a content display method according to an embodiment of the present disclosure. The flow of the content display method provided by the embodiment of the application can be as follows:
101. detecting the content to be occluded in the current content displayed on the screen.
In the embodiment of the application, the screen surface of the electronic device is covered with an electrochromic assembly, and the electrochromic assembly comprises a plurality of electrochromic units, or the electrochromic assembly consists of a plurality of electrochromic units. It should be noted that, for the number of electrochromic elements included in the electrochromic device, the number is not specifically limited in the embodiments of the present application, and can be set by a person skilled in the art according to actual needs.
For example, referring to fig. 2, in the embodiment of the present application, the electrochromic device covered on the screen surface of the electronic device includes 66 electrochromic cells in total 6 × 11.
The electrochromic is a phenomenon that the optical properties (such as reflectivity, light transmittance and absorption rate) of the material are changed stably and reversibly in color/transparency under the action of an external electric field. Materials with electrochromic properties may be referred to as electrochromic materials. The electrochromic unit in the embodiment of the present application is made of electrochromic materials.
Referring to fig. 3, the electrochromic cell may include two conductive layers stacked on each other, and a color-changing layer, an electrolyte layer, and an ion storage layer disposed between the two conductive layers.
Among them, the conductive layer may be a transparent conductive layer, which has excellent conductivity and good optical transmittance. The transparent conductive layer may be made of Indium Tin Oxide (ITO), tin oxide (SnO2), Antimony Tin Oxide (ATO), and the like.
The color-changing layer is a core layer of the electrochromic unit and is also a generation layer of color-changing reaction. The material of the color-changing layer may be classified into an inorganic electrochromic material and an organic electrochromic material according to types. The inorganic electrochromic material may be tungsten trioxide (WO3), nickel oxide (NiO), or the like. The organic electrochromic material mainly comprises polythiophene and derivatives thereof, viologen, tetrathiafulvalene, metal phthalocyanine compounds and the like.
The electrolyte layer is composed of a special conductive material such as a liquid electrolyte material containing a solution of lithium perchlorate, sodium perchlorate, or the like, or may be a solid electrolyte material.
The ion storage layer plays a role in storing charges in the electrochromic unit, namely corresponding counter ions are stored when the material of the electrochromic layer undergoes an oxidation-reduction reaction, so that the charge balance of the whole electrochromic unit is ensured.
Referring to fig. 4, when a certain voltage is applied to the two transparent conductive layers of the electrochromic cell, the material of the color-changing layer of the electrochromic cell undergoes an oxidation-reduction reaction under the voltage, so that a color/transparency change occurs.
For example, when no voltage (or 0V) is applied to the two transparent conductive layers of the electrochromic cell, the electrochromic cell will be in a transparent state, when the voltage applied between the two transparent conductive layers is changed from 0V to 1.2V, the electrochromic cell will be in a black color, when the voltage applied between the two transparent conductive layers is changed from 1.2V to-1.2V, the electrochromic cell will be changed from black color to transparent, and so on.
It should be noted that the current content displayed on the screen does not refer to a certain content, and may be any content in the electronic device, such as picture content and text content stored in the electronic device, as well as short message content and instant messaging information content received in real time, and the like.
In the embodiment of the application, the electronic equipment detects the current content displayed on the screen of the electronic equipment in real time according to a preset detection rule so as to detect whether the current content contains the content to be shielded. For example, the electronic device may detect sensitive content including password information, identity information of a user, and the like as content to be blocked; for another example, the electronic device may detect, as the content to be occluded, the content selected by the selection operation according to the selection operation input by the owner, and the like.
102. And determining a target area covering the content to be blocked in the electrochromic component.
In the embodiment of the application, when the electronic device detects that the current content displayed on the screen has the content to be blocked, a target area covering the content to be blocked in the electrochromic assembly is further determined according to a screen area corresponding to each electrochromic unit in the electrochromic assembly, and the target area may be formed by one electrochromic unit or by a combination of a plurality of electrochromic units.
For example, referring to fig. 5, a target area covering a content to be blocked in an electrochromic component determined by an electronic device is formed by an electrochromic unit filled with black in a diagram; for another example, referring to fig. 6, a target area covering a content to be blocked in an electrochromic component determined by an electronic device is formed by four electrochromic cells filled with black in a diagram.
103. And switching the target area in the electrochromic assembly from a transparent state to a coloring state to shield the content to be shielded.
In the embodiment of the present application, each electrochromic unit in the electrochromic device is initially in a transparent state. After the electronic equipment determines a target area covering the content to be shielded from the electrochromic assembly, one or more electrochromic units forming the target area are switched from a transparent state to a coloring state.
The color of the electrochromic unit forming the target area after being colored is not particularly limited in the embodiment of the present application, and may be preset by a person skilled in the art according to actual needs, for example, the color may be set to black, so that after the electrochromic unit forming the target area is switched to a colored state by the electronic device, the electrochromic unit forming the target area will be black, and thus, the to-be-shielded content displayed on the screen will be shielded by these black electrochromic units.
As can be seen from the above, in the electronic device in the embodiment of the present application, the surface of the screen is covered with the electrochromic component, and the electronic device may first detect the content to be blocked from the current content displayed on the screen, then determine the target area in the electrochromic component, which covers the content to be blocked, and finally switch the target area in the electrochromic component from the transparent state to the colored state, so as to block the content to be blocked, and prevent others from viewing the content. Therefore, the technical scheme provided by the application can improve the safety of the display content of the electronic equipment.
In one embodiment, the "detecting content to be occluded in the current content of the screen display" includes:
(1) detecting a first pressing operation on a screen;
(2) and determining a first pressing position of the first pressing operation, and determining the content which is positioned in a preset range of the first pressing position in the current content displayed on the screen as the content to be shielded.
As an optional implementation manner, in the embodiment of the present application, content to be occluded in current content displayed on a screen is detected according to a user operation.
In the embodiment of the application, the electronic equipment is provided with the pressure sensor for detecting the pressing operation, and the pressure sensor can be arranged below the screen, so that when the screen displays, the electronic equipment can detect the pressing operation on any position of the screen through the arranged pressure sensor.
When the electronic equipment detects the content to be shielded in the current content displayed on the screen, the electronic equipment receives the pressing operation on the screen through the set pressure sensor in real time, and the detected pressing operation is recorded as a first pressing operation.
For example, when the user finds that there is a sensitive content that is not wanted to be viewed by others and other people can see the screen of the electronic device in the current content displayed on the screen of the electronic device, the user can press the sensitive content displayed on the screen with a finger, and accordingly, the electronic device receives a first pressing operation input by pressing the screen with the finger of the user.
After receiving the first pressing operation on the screen, the electronic equipment further determines a pressing position of the first pressing operation, and records the pressing position as the first pressing position. After the first pressing position of the first pressing operation is determined, the electronic equipment determines the content in the preset range of the first pressing position in the current content displayed on the screen as the content to be shielded.
It should be noted that, as to the size and the shape of the preset range, a person skilled in the art can set the preset range according to actual needs, which is not specifically limited in the embodiment of the present application, for example, the preset range may be set to be a circular area range with a first pressing position as a center of a circle and a radius of 64 pixels; for another example, the preset range may be a square area range having a diagonal length of 64 pixels and the first pressing position as a center, and the like.
In one embodiment, "switching a target area in an electrochromic assembly from a transparent state to a colored state" includes:
(1) determining a pressure value of the first pressing operation;
(2) determining a first target color corresponding to the pressure value according to the pressure value and a preset corresponding relation between the pressure value and the color;
(3) the target area in the electrochromic assembly is controlled to display a first target color.
It should be noted that, in the embodiment of the present application, the electronic device is preset with the corresponding relationship between the pressure value and the color, and the electronic device can be set by a person skilled in the art according to actual needs, which is not specifically limited by the embodiment of the present application, for example, the color corresponding to the pressure value interval (0N, 5N) can be set to be red, and the color corresponding to the pressure value interval (5N, + ∞) can be set to be black.
When the electronic equipment switches a target area in the electrochromic assembly from a transparent state to a coloring state, a pressure value of a first pressing operation is determined firstly, then a first target color corresponding to the pressure value is determined according to the pressure value and a corresponding relation between a preset pressure value and a color, and finally an electrochromic unit forming the target area is controlled to be in the first target color.
For example, assuming that the determined pressure value of the first pressing operation is 8N, the electronic device further determines that the first target color corresponding to the pressure value "8N" is black, and supplies a voltage of 1.2V to the electrochromic cell forming the target area, so that the electrochromic cell forming the target area is colored and appears black.
In one embodiment, after "switching the target area in the electrochromic device from the transparent state to the colored state", the method further includes:
(1) detecting a second pressing operation on the screen;
(2) determining a second pressing position of the second pressing operation, and judging whether the second pressing position is located within the preset range;
(3) if so, switching the target area in the electrochromic component from the colored state to the transparent state.
In the embodiment of the application, a scheme for canceling the occlusion display is continuously provided. After the target area in the electrochromic assembly is switched from the transparent state to the colored state, namely after the displayed content to be shielded is shielded, the electronic device receives the pressing operation on the screen through the arranged pressure sensor in real time, and the detected pressing operation is recorded as a second pressing operation.
For example, when a user finds that there is sensitive content that is not wanted to be viewed by others and that others can see the screen of the electronic device in the current content displayed on the screen of the electronic device, the user can press the sensitive content displayed on the screen with a finger to control the electronic device to shield the sensitive content through the electrochromic component. Then, when the other person leaves, the user can press the shielded and displayed sensitive content through the finger, and accordingly, the electronic device receives a second pressing operation input by pressing the screen through the finger of the user.
After receiving the second pressing operation on the screen, the electronic equipment further determines the pressing position of the second pressing operation, and records the pressing position as the second pressing position. After the second pressing position of the second pressing operation is determined, the electronic equipment judges whether the second pressing position is located within the preset range, if yes, the second pressing position is determined as the triggering operation for triggering the cancellation of the shielding display, and at the moment, the electrochromic unit forming the target area is switched from the coloring state to the transparent state.
For example, the electrochromic cell forming the target area is black after being switched from the transparent state to the colored state, and when the second operation is a trigger operation for triggering the undone of the shielding display, the electronic device supplies a voltage of-1.2V to the electrochromic cell forming the target area, so that the electrochromic cell forming the target area is switched from the colored state to the transparent state, that is, from black to transparent.
In one embodiment, the step of detecting the content to be occluded in the current content displayed on the screen includes:
(1) identifying whether a preset user and other users except the preset user exist in a visual range of a screen;
(2) and if so, determining the privacy content of the associated preset user in the current content displayed on the screen as the content to be blocked.
As an optional implementation manner, in the embodiment of the present application, the electronic device automatically identifies content to be occluded in the current content displayed on the screen.
In the embodiment of the application, when the electronic device displays the screen, whether a preset user (which may be a user owner or an authorized user authorized by the user owner) or other users except the preset user exists in a visual range of the screen is identified in real time. The electronic equipment can identify whether the preset user and other users exist in the visual range of the screen through the front camera, and can also identify whether the preset user and other users exist in the visual range of the screen through the microphone.
When the preset user and other users are identified to be in the visual range of the screen, the electronic equipment determines the privacy content of the preset user in the current content displayed by the screen, and determines the privacy content as the content to be shielded. For example, when the preset user is the owner, the electronic device determines the current content displayed on the screen and the privacy content associated with the owner as the content to be blocked, and when the preset user is the authorized user, the electronic device determines the current content displayed on the screen and the privacy content associated with the authorized user as the content to be blocked.
The privacy content may be preset by a preset user according to actual needs, which is not specifically limited in the embodiment of the present application, for example, an owner may set an image including the owner as the privacy content.
In the embodiment of the application, the electronic device is further provided with a privacy content setting interface, which is used for receiving privacy content setting information input by a preset user and configuring detection conditions associated with the preset user according to the received privacy content setting information, so that after the preset user and other users in a screen visual range are identified, the privacy content associated with the preset user is detected in current content displayed on a screen by using the detection conditions associated with the detected preset user and serves as the content to be shielded.
In one embodiment, "identifying whether a preset user, a user other than the preset user, exists within the visual range of the screen" includes:
(1) acquiring a real-time image through a front camera;
(2) acquiring a face image in a real-time image, and judging whether the acquired face image contains a face image of a preset user and other face images;
(3) if yes, determining that the preset user and other users corresponding to other face images exist in the visual range.
As an optional implementation manner, the electronic device may recognize whether a preset user and a related user of the preset user exist in a visual range of the current application through the front-facing camera.
In the embodiment of the application, the electronic equipment performs shooting operation through the front camera in real time so as to shoot a real-time image corresponding to the visual range of the screen. After the real-time image is obtained by shooting, the electronic device performs face detection on the real-time image by using a face detection algorithm (such as an AdaBoost method, a classification regression tree method, a neural network method, and the like), so as to obtain a face image in the real-time image. It should be noted that, as to what face detection algorithm is used, the embodiment of the present application does not specifically limit this, and a person skilled in the art can select this according to actual needs.
After the face image in the real-time image is acquired, the acquired face image is compared with a preset face image associated with the preset user. The preset face image is a face image of a preset user acquired in advance, and if the similarity between the acquired face image and the preset face image reaches a preset similarity (the value of the preset similarity can be set by a person skilled in the art according to actual needs, which is not specifically limited in the embodiment of the present application, for example, the preset similarity can be set to 90%), the face image is determined to be the face image corresponding to the preset user, it is determined that the preset user exists in the visual range of the screen at this time, and if other face images are acquired from the real-time image, it is determined that other users corresponding to the other face images also exist in the visual range of the screen at this time.
In one embodiment, "switching a target area in an electrochromic assembly from a transparent state to a colored state" includes:
(1) acquiring the area percentage of the other face images in the real-time image;
(2) determining a distance value corresponding to the area percentage according to the acquired area percentage and a preset corresponding relation between the area percentage and the distance value;
(3) determining a second target color corresponding to the distance value according to the determined distance value and a preset corresponding relation between the distance value and the color;
(4) and controlling the target area in the electrochromic assembly to display a second target color.
It should be noted that, in the embodiment of the present application, the electronic device is preset with the corresponding relationship between the distance value and the color, and the corresponding relationship can be set by a person skilled in the art according to actual needs, and the embodiment of the present application does not specifically limit this, for example, the color corresponding to the distance value interval (0,1 m) may be set to be black, and the color corresponding to the distance value interval (1m, infinity) may be set to be red.
In addition, the corresponding relation between the area percentage and the distance value is preset in the electronic equipment. It is easy to understand that, for the same object, the distance values of the object from the front-facing camera of the electronic device are different, and the area percentages of the image areas of the object in the images at different distances, which are obtained by shooting by the electronic device, in the whole image will also be different. Therefore, in the embodiment of the application, the electronic device may shoot the same object placed at different known distance values through the front camera, and calculate the area percentage corresponding to the object corresponding to each known distance value, so as to obtain the corresponding relationship between the area percentage and the distance value.
When the electronic equipment switches the target area in the electrochromic component from a transparent state to a coloring state, firstly, the area percentage of the other face images in the real-time image is acquired; then, according to the obtained area percentage and the corresponding relation between the preset area percentage and the distance value, determining the distance value corresponding to the area percentage, namely the distance value from the current user to the other users; and determining a second target color corresponding to the distance value according to the determined distance value and the preset corresponding relation between the distance value and the color. For example, assuming that the determined current distance value from the other users is 80cm, the electronic device further determines that the second target color corresponding to the distance value of "80 cm" is black, and supplies a voltage of 1.2V to the electrochromic cells forming the target area, so that the electrochromic cells forming the target area are colored and appear black.
It should be noted that, when there are a plurality of other users, the electronic device may determine a distance value with a minimum value from among distance values from the plurality of other users, determine a corresponding second target color according to the distance value with the minimum value and a preset correspondence between the distance value and the color, and control a target area in the electrochromic assembly to display the second target color.
In addition, after the electronic equipment controls a target area in the electrochromic assembly to display a second target color, a real-time image is acquired in real time through the front camera, the acquired real-time image is recorded as a second real-time image, face recognition is carried out on the second real-time image, and if the fact that the second real-time image only comprises the face image of the preset user is recognized, the electrochromic unit forming the target area is controlled to be switched from a coloring state to a transparent state.
For example, after the electrochromic cell forming the target area is black (i.e. the second target color is black) after being switched from the transparent state to the colored state, if it is recognized that the second real-time image only includes the facial image of the preset user, the electronic device provides a voltage of-1.2V to the electrochromic cell forming the target area, so that the electrochromic cell forming the target area is switched from the colored state to the transparent state, i.e. from black to transparent.
Referring to fig. 7, fig. 7 is another schematic flow chart of a content display method according to an embodiment of the present disclosure, and as shown in fig. 7, the content display method may include:

When the electronic equipment displays a screen, the pressing operation of the screen is received by the arranged pressure sensor in real time, and the detected pressing operation is recorded as a first pressing operation.
For example, when the user finds that there is a sensitive content that is not wanted to be viewed by others and other people can see the screen of the electronic device in the current content displayed on the screen of the electronic device, the user can press the sensitive content displayed on the screen with a finger, and accordingly, the electronic device receives a first pressing operation input by pressing the screen with the finger of the user.
202. And determining a first pressing position of the first pressing operation, and determining the content which is positioned in a preset range of the first pressing position in the current content displayed on the screen as the content to be shielded.

After the first pressing position of the first pressing operation is determined, the electronic equipment determines the content in the preset range of the first pressing position in the current content displayed on the screen as the content to be shielded.
It should be noted that, as to the size and the shape of the preset range, a person skilled in the art can set the preset range according to actual needs, which is not specifically limited in the embodiment of the present application, for example, the preset range may be set to be a circular area range with a first pressing position as a center of a circle and a radius of 64 pixels; for another example, the preset range may be a square area range having a diagonal length of 64 pixels and the first pressing position as a center, and the like.
