Referring to fig. 1, fig. 1 is a schematic flow chart of an apparatus control method according to an embodiment of the present disclosure. The flow of the device control method provided by the embodiment of the application can be as follows:

101. and identifying whether a preset user and other users except the preset user exist in the visual range of the screen.

In the embodiment of the application, when the electronic device displays the screen, according to a preset identification period, when the identification period is reached each time, whether a preset user (which may be a user owner or an authorized user authorized by the user owner) and other users except the preset user exist in the visual range content of the screen is identified. The electronic device can identify whether a 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, and the like. It should be noted that, for a specific value of the identification period, a person skilled in the art may set the value according to actual needs, which is not specifically limited in the embodiment of the present application, for example, the value may be set to 1 second, so that the electronic device identifies once per second whether the preset user exists in the visual range of the screen of the electronic device, and identifies other users besides the preset user.

102. When a preset user and other users exist in the visual range of the screen, the distance value between the other users and the screen is obtained.

In the current identification period, after the electronic device completes identification of whether a preset user exists in a visual range of a screen of the electronic device and other users except the preset user, if the preset user and other users exist in the visual range of the screen of the electronic device, a distance value between the other users and the screen is further acquired, for example, the distance sensor can be used to acquire the distance value between the other users and the screen.

103. And determining the target transparency corresponding to the distance value, and adjusting the transparency of the electrochromic component to the determined target transparency so as to block other users from viewing the screen.

Referring to fig. 2, in the embodiment of the present application, an electrochromic element covers a surface of a screen of an electronic device, and the electronic device can dynamically adjust a transparency of the electrochromic element to adjust a display definition of the screen, for example, when the transparency of the electrochromic element is increased, light emitted from the screen can more penetrate through the electrochromic element and is projected into eyes of a user, so as to increase the display definition of the screen; for another example, when the transparency of the electrochromic element is reduced, less light is emitted from the screen through the electrochromic element and projected to the eyes of the user, thereby reducing the clarity of the screen display.

The operating principle of the electrochromic assembly will first be briefly described below.

The electrochromic is a phenomenon that the color/transparency of the material is changed stably and reversibly under the action of an external electric field. Materials with electrochromic properties may be referred to as electrochromic materials. The electrochromic component in the embodiment of the present application is made of electrochromic materials.

Referring to fig. 3, the electrochromic device 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 assembly 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 component, 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 component is ensured.

Referring to fig. 4, when a certain voltage is applied to the two transparent conductive layers of the electrochromic device, the material of the color-changing layer of the electrochromic device undergoes an oxidation-reduction reaction under the action of 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 device, the transparency of the electrochromic device is maximum, and when the voltage applied between the two transparent conductive layers of the electrochromic device is gradually increased, the transparency of the electrochromic device is gradually reduced until the electrochromic device is opaque.

Thus, by utilizing the characteristic that the transparency of the electrochromic component can be adjusted, when the screen is displayed with specific definition, the closer to the screen, the more the screen display can be seen, and the farther from the screen, the more the screen display can not be seen. Based on this, in the embodiment of the present application, a corresponding relationship between a distance value and a transparency is preset in an electronic device, where the corresponding relationship is used to describe: when the transparency of the electrochromic assembly is adjusted to the transparency corresponding to the distance value between the user and the screen, the user cannot see the screen display clearly, so that the effect of blocking other users from viewing the screen is achieved.

Correspondingly, in the embodiment of the application, after the electronic device obtains the distance value between the other user and the screen, the target transparency corresponding to the distance value is determined according to the preset distance value and the transparency corresponding relation, and the transparency of the electrochromic component is adjusted to be the determined target transparency, so that the other user cannot see the screen display clearly, and the preset user usually holds the electronic device for use, so that the preset user is closer to the screen than the other user, and can see the screen display clearly to a certain extent.

It should be noted that, when the electronic device adjusts the transparency of the electrochromic device according to the distance value, the electronic device may adjust between the minimum transparency and the maximum transparency of the electrochromic device, or may adjust between a transparency greater than the minimum transparency of the electrochromic device and a transparency less than the maximum transparency of the electrochromic device.

As can be seen from the above, when the electronic device in the embodiment of the application has the preset user and other users in the visual range of the screen, the transparency of the electrochromic component covered on the screen can be adjusted according to the distance value between the other users and the screen, so that the other users cannot see the screen display clearly, and the effect of shielding the other users from viewing the screen is achieved. Therefore, the technical scheme provided by the application can improve the safety of the display content of the electronic equipment.

In one embodiment, the electrochromic assembly includes a plurality of electrochromic cells, and adjusting the transparency of the electrochromic assembly to a target transparency includes:

(1) determining privacy content associated with a preset user from current content displayed on a screen;

(2) determining a target area covering the private content in the electrochromic component;

(3) determining a target electrochromic unit forming a target area from the plurality of electrochromic units;

(4) and adjusting the transparency of the target electrochromic unit to the target transparency.

As an alternative, in the embodiment of the present application, the electrochromic assembly is composed of a plurality of independently controllable electrochromic units (one electrochromic unit can be regarded as a "small" electrochromic assembly, and the structure of the electrochromic assembly is the same as that of the complete electrochromic assembly), so that the electrochromic assembly is area-controllable (one or more electrochromic units form different areas). It should be noted that, in the embodiment of the present application, the number of electrochromic units constituting the electrochromic assembly, the shape of the electrochromic unit, and the like are not specifically limited, and can be set by those skilled in the art according to actual needs. Among them, it is easily understood that the more electrochromic cells included in the electrochromic device, the more precise the zone control of the electrochromic device can be performed.

For example, referring to fig. 5, in the embodiment of the present application, the electrochromic device covered on the screen surface of the electronic device is composed of 66 electrochromic cells, 6 × 11.

In the embodiment of the application, each electrochromic unit of the electrochromic assembly is initially displayed with the maximum transparency. When the transparency of the electrochromic assembly is adjusted to the target transparency by the electronic equipment, the electronic equipment determines the privacy content of the preset user in the current content displayed on the screen, and takes the privacy content as the content to be shielded. For example, when the preset user is the owner, the electronic device uses the privacy content associated with the owner in the current content displayed on the screen as the content to be blocked, and when the preset user is the authorized user, the electronic device uses the privacy content associated with the authorized user in the current content displayed on the screen 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.

After the electronic device determines the privacy content associated with the preset user, a target area covering the privacy content in the electrochromic component is further determined according to the area corresponding relation between the electrochromic component and the screen, and a target electrochromic unit forming the target area is determined from a plurality of electrochromic units forming the electrochromic component according to the position of each electrochromic unit forming the electrochromic component, wherein the number of the determined target electrochromic units can be one or a plurality. For example, referring to fig. 6, the determined target area is an area marked with black in the drawing, as shown in fig. 6, the target area is composed of 4 electrochromic cells, and accordingly, the electronic device determines the 4 electrochromic cells constituting the target area as target electrochromic cells.

After the target electrochromic unit is determined, the electronic device can adjust the transparency of the target electrochromic unit and adjust the transparency of the target electrochromic unit to the determined target transparency, so that the private content displayed on the screen cannot be seen by other users, and other contents except the private content can be clearly seen by the preset user.

In one embodiment, the electronic device further comprises an energy conversion component for converting external energy into electrical energy, and the "adjusting the transparency of the target electrochromic cell to the target transparency" comprises:

(1) determining a target voltage corresponding to the target transparency according to a preset corresponding relation between the transparency and the voltage;

(2) and providing a target voltage for the target electrochromic unit based on the energy conversion assembly, and adjusting the transparency of the target electrochromic unit to be the target transparency through the target voltage.

It should be noted that, in the embodiment of the present application, the electronic device further includes an energy conversion component, and the energy conversion component is configured to convert external energy into electrical energy, and the embodiment of the present application is not particularly limited to the physical display form of the energy conversion component, for example, the energy conversion component may be a wireless receiving coil, and can convert external electromagnetic energy into electrical energy, so as to provide the target voltage to the target electrochromic cell; for another example, the energy conversion component may be a solar panel capable of converting external light energy into electric energy for providing the target electrochromic cell with the aforementioned target voltage, and so on.

In the embodiment of the application, when the electronic device adjusts the transparency of the target electrochromic cell, firstly, according to a preset corresponding relationship between the transparency and the voltage (which may be preset in the electronic device by a person skilled in the art according to the material characteristics of the electrochromic material used in the electrochromic cell), a voltage corresponding to the target transparency is determined, and the voltage is recorded as a target voltage for providing to the target electrochromic cell.

For example, assume that the preset correspondence between transparency and voltage is configured as: the transparency 50% corresponds to a voltage of 1V, the transparency 0 corresponds to a voltage of 3V, and if the determined target transparency is 50%, the target voltage for supplying to the target electrochromic cell may be determined to be 1V, and if the determined target transparency is 0, the target voltage for supplying to the target electrochromic cell may be determined to be 3V.

When the electronic device provides the target voltage to the target electrochromic cell, the external energy can be converted into the electric energy based on the energy conversion component, and the target voltage is provided to the target electrochromic cell through the energy conversion component. When the output voltage obtained by converting external energy by the energy conversion assembly is higher than the target voltage, the output voltage of the energy conversion assembly can be reduced by a preset voltage reduction circuit to obtain the target voltage, and the target voltage obtained by reducing the voltage is provided for the target electrochromic unit; for another example, when the output voltage obtained by converting the external energy by the energy conversion assembly is lower than the target voltage, the output voltage of the energy conversion assembly may be boosted by a preset boost circuit to obtain the target voltage, and the boosted target voltage may be provided to the target electrochromic cell.

Therefore, when the electronic equipment realizes the transparency adjustment of the target electrochromic unit through the energy conversion assembly, the electric quantity of the built-in battery is not required to be consumed, and the service life of the electronic equipment can be prolonged.

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 the real-time image, and judging whether the acquired face image contains a face image of a preset user and other face images;

(3) and when the face image of the preset user and other face images exist in the acquired face image, determining that the preset user and other users corresponding to the other face images exist in the visual range of the screen.

As an optional implementation manner, the electronic device may recognize whether a preset user and an associated user of the preset user exist in a visual range of a screen of the electronic device through a front-facing camera.

In the embodiment of the application, when whether a preset user and other users except the preset user exist in the visual range of the screen is identified, the electronic equipment performs shooting operation through the front-facing camera 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 visible range of the screen at the 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 exist in the visible range of the screen at the time.

In one embodiment, the "acquiring the distance value between the other user and the screen" includes:

(1) acquiring the area percentage of the other face images in the real-time image;

(2) determining a distance value corresponding to the acquired area percentage according to the acquired area percentage and a preset corresponding relation between the area percentage and the distance value;

(3) and taking the distance value corresponding to the area percentage as the distance value between the other users and the screen.

In the embodiment of the application, 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.

Correspondingly, when the electronic device obtains the distance value between the other user (i.e. the other user corresponding to the other face image) and the screen, first obtaining the area percentage of the other face image in the real-time image; and then 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, and taking the distance value corresponding to the area percentage as the distance value between the other users and the screen.

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, and then determine a target transparency, which needs to be adjusted, of the electrochromic component according to the distance value with the minimum value and a preset correspondence between the distance value and the transparency.

In an embodiment, "identifying whether there are a preset user and other users except the preset user within the visual range of the screen" further includes:

when the preset user does not exist in the visual range of the screen, the transparency of the electrochromic assembly is adjusted to be a first preset transparency, and the first preset transparency is smaller than or equal to the minimum transparency which can be adjusted according to the distance value.

In the current recognition period, after the electronic device recognizes whether a preset user exists in the visual range of the screen of the electronic device and other users except the preset user, if it is recognized that the preset user does not exist in the visual range of the screen, the transparency of the electrochromic component is directly adjusted to a first preset transparency, and the first preset transparency is smaller than or equal to a minimum transparency adjustable according to the distance value, for example, the first preset transparency can be set to the minimum transparency of the electrochromic component. Therefore, after the transparency of the electrochromic assembly is adjusted to be the first preset transparency by the electronic equipment, the definition of screen display is changed to be the lowest, and at the moment, any user cannot see the screen display clearly, so that the effect of completely shielding the screen display is achieved.

In an implementation manner, the apparatus control method provided in the embodiment of the present application further includes

And when only a preset user exists in the visual range of the screen, adjusting the transparency of the electrochromic assembly to a second preset transparency, wherein the second preset transparency is greater than or equal to the maximum transparency adjustable according to the distance value.

It should be noted that, in this embodiment of the application, in each recognition period, the electronic device may recognize whether the preset user and other users outside the preset user exist in the visual range of the screen of the electronic device, and correspondingly, in other recognition periods outside the "current recognition period", if the electronic device recognizes that only the preset user exists in the visual range of the screen of the electronic device, the electronic device directly adjusts the transparency of the electrochromic component to the second preset transparency, where the second preset transparency is greater than or equal to the maximum transparency that can be adjusted according to the distance value, for example, the second preset transparency may be set as the maximum transparency of the electrochromic component. Therefore, after the transparency of the electrochromic component is adjusted to the second preset transparency, the definition of the screen display is changed to be the highest, so that the highest screen display effect is provided for the preset user.

Referring to fig. 7, fig. 7 is another schematic flow chart of an apparatus control method according to an embodiment of the present disclosure, and as shown in fig. 7, the apparatus control method may include:

201. and acquiring a real-time image through a front camera.

In the embodiment of the application, when the electronic device displays the screen, according to a preset identification period, when the identification period is reached each time, whether a preset user (which may be a user owner or an authorized user authorized by the user owner) and other users except the preset user exist in the visual range content of the screen is identified. It should be noted that, for a specific value of the identification period, a person skilled in the art may set the value according to actual needs, which is not specifically limited in the embodiment of the present application, for example, the value may be set to 1 second, so that the electronic device identifies once per second whether the preset user exists in the visual range of the screen of the electronic device, and identifies other users besides the preset user.

When whether a preset user and other users except the preset user exist in the visual range of the screen is identified, the electronic equipment firstly carries out shooting operation through the front-facing camera so as to shoot and obtain a real-time image corresponding to the visual range of the screen.

202. And acquiring a face image in the real-time image, and judging whether the acquired face image contains a face image of a preset user and other face images.

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.

203. When the face image of the preset user and other face images exist in the acquired face image, it is determined that the preset user and other users corresponding to the other face images exist in the visual range of the screen.

In the embodiment of the application, when it is determined that a face image of a preset user exists in the acquired face images, the electronic device may determine that the preset user exists in the visual range of the screen at the time, and if other face images are acquired from the real-time image, determine that other users corresponding to the other face images exist in the visual range of the screen at the time.
