Specifically, the configuration signal lines (configuration channel, cc) in the USB interface 106 (e.g., USB type-c interface) of the electronic device 100 may detect the current sent by the power adapter, and enable current transfer between the electronic device 100 and the power adapter.
It should be noted that, in fig. 1, the electronic device 100 is connected to the power adapter through the USB interface 106 as an example, in practical application, the electronic device 100 may also be connected to the power adapter through other manners, for example, the electronic device 100 is connected to the power adapter through a wireless manner (wifi, bluetooth, etc.), or is connected to the power adapter through other types of charging interfaces.

In this embodiment of the present application, the polarizing film set includes a plurality of polarizing films, and the polarizing directions of the polarizing films of each layer are preset to be different, that is, the preset viewing angle of the mobile phone is the maximum value.

It will be appreciated by those skilled in the art that the internal structure of the terminal device shown in fig. 1 does not constitute a limitation of the terminal device, and may include more or less components than illustrated, or may combine certain components, or may be arranged in different components.
Embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
The embodiment of the application provides a method for adjusting a visual angle, and in combination with the embodiment in fig. 3, the method includes:
in step 301, a touch screen of an electronic device receives a touch operation of a user, where the touch operation is used to request adjustment of a visual angle of the touch screen.
The touch operation may be a sliding operation for adjusting the visual angle control, or a clicking operation. For example, as shown in fig. 4, a visual angle adjustment control is provided in the setting of the mobile phone operating system, and when the user drags or slides the progress block, the adjustment of the visual angle can be triggered.
In other possible embodiments, the above touch operation may be replaced by a voice command or other operations, which are not listed in the embodiments of the present application.
In step 302, in response to the touch operation, the processor of the electronic device adjusts the polarization direction of the polarization film group in the touch screen.
Specifically, a processor of the electronic device adjusts the polarization direction of the polarization film group by adjusting the voltage of a circuit module connected to the polarization film group in the touch screen. Illustratively, as the voltage increases, the number of polarizing films in the polarizing film group having the same polarization direction as the first direction decreases, and the viewing angle increases; when the voltage decreases, the number of polarizing films having the same polarization direction as the first direction in the polarizing film group increases, and the viewing angle becomes smaller.
The first direction refers to a line of sight direction within a normal visual field of a user of the electronic device. Illustratively, as shown in fig. 5A, when the user of the mobile phone holds the mobile phone normally, the line of sight direction of the user is a first direction, and the second direction and the third direction shown in fig. 5A are other line of sight directions different from the first direction. As shown in fig. 5B, assuming that the polarizing film group in the display screen of the electronic device includes three layers of polarizing films, the polarization direction of the first layer of polarizing film a is preset to be the first direction, the polarization direction of the second layer of polarizing film B is preset to be the second direction, and the polarization direction of the third layer of polarizing film c is the third direction, when the user reduces the screen visibility, the polarization direction of the second layer of polarizing film B can be made to be the first direction by adjusting the voltage value.
Thus, in one possible embodiment, when step 301 requests an increase in the viewing angle, the processor control voltage of the electronic device is increased so that the number of polarizing films in the polarizing film set having the same polarization direction as the first direction is reduced to achieve that the viewing angle is increased; when step 301 requests a decrease in the viewing angle, the processor control voltage of the electronic device is decreased, so that the number of polarizing films in the polarizing film set having the same polarization direction as the first direction is increased, to achieve that the viewing angle is decreased.
In one possible embodiment, when the touch operation is used to request adjustment of the visual angle of the touch screen to the maximum value, the voltage value is zero, that is, the polarization function of the electronic device is in the off state; when the touch operation is used for requesting to adjust the visual angle of the touch screen to the minimum value, the voltage value is the maximum value, that is, the polarization function of the electronic device is in an on state. In other words, the user can achieve the purpose of turning on or off the polarization function by adjusting the visual angle to be a value.
As shown in fig. 6, it is assumed that the mobile phone in the figure is integrated with the above-mentioned visibility angle adjusting function, and when the mobile phone is set to a higher visibility angle, or the privacy protecting function of the screen is not started, the peeper can clearly view the content on the display screen of the user from other directions, as shown in fig. 6A; when the mobile phone is set with a medium visual angle, the peeper can barely check the content on the display screen of the user from other directions, as shown in fig. 6B; when the cell phone is set at a low visual angle, the peeper cannot view the content on the user display screen from other directions, as shown in fig. 6C.
From the above, the embodiment of the application uses the characteristics of the polarizing film, that is, natural light can be converted into polarized light through the polarizing film, so that the visual angle of light can be adjusted by using the polarizing films corresponding to different polarization directions. Compared with the prior art, the polarizing film in the embodiment of the application is built in the screen, can be a combination of one or more polarizing films, is an active design, is not a passive remedy measure stuck on the screen, and the polarizing characteristics of the polarizing films can be controlled through electric signals to realize the effects of opening and closing or different-sized view angles.
Based on the above method for adjusting the visibility angle of the terminal device, the embodiment of the application also provides an electronic device, which can be used to execute the method for adjusting the visibility angle of the terminal device shown in fig. 3. As shown in fig. 7, the terminal device 700 includes a processor 701 and a display 702.
The display 702 is configured to receive a touch operation from a user, where the touch operation is used to request adjustment of a visual angle of the touch screen.
The processor 701 is configured to obtain a touch event corresponding to the touch operation from the display screen, and adjust a polarization direction of a polarization film group in the touch screen in response to the touch operation; when the touch operation is used for requesting to increase the visual angle, the number of polarizing films with the same polarizing direction as the first direction in the polarizing film group is reduced; when the touch operation is used for requesting to reduce the visual angle, the number of polarizing films with the same polarizing direction as the first direction in the polarizing film group is increased.
In a possible embodiment, the electronic device determines a voltage value corresponding to the adjusted visibility angle according to the touch operation request; and adjusting the voltage of the electric signal connected with the polarizing film group to the voltage value so as to adjust the polarization direction of the polarizing film group in the touch screen.
In a possible embodiment, when the touch operation is used for requesting to adjust the visual angle of the touch screen to a maximum value, the voltage value is zero, and the polarization function of the electronic device is in a closed state; when the touch operation is used for requesting to adjust the visual angle of the touch screen to the minimum value, the voltage value is the maximum value, and the polarization function of the electronic equipment is in an on state.
In one possible embodiment, the touch screen includes a glass panel, a polarizing film set including at least one polarizing film, a touch panel, and a display panel, the polarizing film set being located at a lower layer of the glass panel and at an upper layer of the touch panel.
In one possible embodiment, the set of polarizing films has linear polarization characteristics, and different polarizing films of the set of polarizing films are preset to different polarization directions.
In one possible embodiment, the touch operation is used to adjust a sliding operation or a clicking operation of the visual angle control.
