All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The embodiment of the invention provides a control method of a display screen, the display screen and electronic equipment, wherein the electronic equipment can comprise equipment such as a mobile phone, a computer, a tablet computer and the like, and the details are respectively described below.
Referring to fig. 1, fig. 1 specifically illustrates an electronic device 100 according to an embodiment of the present invention, which includes a cover plate 101, a display screen 102, a circuit board 103 provided with a chip (not shown in the figure), a battery 104, a housing 105, an emitting electrode M, and a receiving electrode N, wherein an accommodating cavity is formed between the display screen 102 and the housing 105, and the circuit board 103 and the battery 104 are installed in the accommodating cavity. The transmitting electrode M and the receiving electrode N are located below the display screen 102, and the chip is electrically connected with the transmitting electrode M and the receiving electrode N through wires so as to transmit or receive electric signals. When the transmitting electrode M transmits an electrical signal, an induced electric field is formed between the transmitting electrode M and the receiving electrode N, and the receiving electrode N can receive the induced signal in the induced electric field.
In this embodiment, the working modes of the display screen 102 include a floating mode and a contact mode, the floating mode is a mode in which a human body can realize a touch function without touching the display screen 102, and the contact mode is a mode in which the human body needs to touch the display screen 102 to realize the touch function. When the voltage value of the transmitting electrode M is greater than or equal to a first preset threshold, the working mode of the display screen 102 is in a floating mode; when the voltage value of the transmitting electrode M is smaller than a first preset threshold, the operation mode of the display screen 102 is in a touch mode.
Specifically, first, the chip may obtain the electric quantity information of the electronic device 100 and the current working mode of the display screen 102, and if the electric quantity information is smaller than a third preset threshold and the current working mode is the floating mode, the chip may generate a mode switching signal; if the electric quantity information is greater than or equal to the third preset threshold and the current working mode is the contact mode, the chip may generate a mode switching signal according to the currently active application information of the electronic device 100. Then, when a mode switching signal is detected, the chip may further control the display screen 102 to switch from the current operating mode to another operating mode, that is, if the current operating mode is the contact mode, the chip increases the voltage of the emitter electrode M to a first preset threshold value, so that the operating mode of the display screen 102 is switched to the suspension mode, at this time, the display screen 102 may perform screen off or screen on according to the number of preset waveforms in the sensing signal received by the receiver electrode N, for example, when the number is less than a certain value, the display screen 102 is off, and when the number is greater than the certain value, the display screen 102 is on; if the current operating mode is the floating mode, the chip reduces the voltage of the emitter electrode M to be less than a first predetermined threshold, so that the operating mode of the display screen 102 is switched to the touch mode.
As can be seen from the above description, in the display screen 102 and the electronic device 100 provided in this embodiment, the display screen 102 includes the floating mode and the contact mode, and when the mode switching signal is detected, the working mode of the display screen 102 is switched from the current working mode to another working mode, so that the display screen 102 can be freely switched between the contact touch mode and the non-contact touch mode, and the method is simple and has a wide application range.
On the basis of the display screen and the electronic device described in the above embodiments, the present invention further provides a control method of a display screen, please refer to fig. 2, the control method of a display screen is applied to an electronic device, the electronic device includes a display screen, the working mode of the display screen includes a floating mode and a touch mode, and the control method may include:
and S101, acquiring the current working mode of the display screen.
In this embodiment, the current working mode is one of a floating mode and a contact mode, where the floating mode is a touch mode in which a human body can realize a touch function without touching a display screen, and the contact mode is a touch mode in which a human body needs to touch a display screen to realize a touch function. The obtaining operation of the current working mode may be real-time obtaining, or may be triggered and executed according to a user operation, for example, when a user starts to make a call or finishes making a call, the obtaining operation of the current working mode may be triggered and executed, which may be specifically determined according to an actual requirement.
And S102, generating a mode switching signal according to the current working mode.
For example, before the step S102, the method may further include:
acquiring current electric quantity information of the electronic equipment;
and generating a mode switching signal based on the electric quantity information and the current working mode.
In this embodiment, the electric quantity information may include a specific numerical value, and may also include an electric quantity state indicating how much electric quantity is, and the electric quantity state may include three states of a high electric quantity, a medium electric quantity, and a low electric quantity.
For example, the step "generating the mode switching signal based on the electric quantity information and the current operating mode" may specifically include:
if the electric quantity information is smaller than a third preset threshold value and the current working mode is the suspension mode, generating a mode switching signal;
if the electric quantity information is larger than or equal to a third preset threshold value and the current working mode is a contact mode, acquiring currently active application information of the electronic equipment; and when the application information is a preset application, generating a mode switching signal.
In this embodiment, the electric quantity information may include an electric quantity value, which may be expressed in a percentage form, such as 30%, 40%, and the like. The preset application may be determined according to actual requirements, and may be a telephone application, for example. When the electric quantity value is lower than the third preset threshold value, the electric quantity of the electronic equipment is low at the moment, and because the electric quantity value required to be consumed in the floating mode is far larger than that required to be consumed in the contact mode, under the condition of low electric quantity, if the current working mode is the floating mode, the mode switching signal can be generated, otherwise, the mode switching signal does not need to be generated. When the electric quantity value is greater than or equal to the third preset threshold value, it is indicated that the electric quantity of the electronic device is sufficient to meet the requirement of the floating mode, at this time, the use condition of the current application needs to be further analyzed, and the mode switching signal can be generated only when the current active application is a preset application, wherein the current active application refers to a currently running application and is not a background running application.
S103, switching the working mode of the display screen from the current working mode to another working mode according to the mode switching signal.
For example, the display screen is provided with an emitting electrode, and the switching of the working mode of the display screen from the current working mode to another working mode according to the mode switching signal includes:
if the current working mode is the contact mode, increasing the voltage of the transmitting electrode to a first preset threshold value so as to switch the working mode of the display screen to the suspension mode;
if the current working mode is the suspension mode, the voltage of the transmitting electrode is reduced to be smaller than a first preset threshold value, so that the working mode of the display screen is switched to a contact mode.
In this embodiment, the first preset threshold may be determined according to an actual requirement, for example, may be determined according to a sensing sensitivity of a display screen, and generally, the more sensitive the sensing is, the larger the first preset threshold is. Preferably, the voltage of the transmitting electrode can be increased in various ways, for example, by adjusting the duty ratio of a transistor in a designated circuit (such as a touch screen driving circuit), or by connecting other boosting circuits.
For example, the display screen may further include a receiving electrode, and in this case, after "forming an induced electric field between the receiving electrode and the transmitting electrode and increasing the voltage of the transmitting electrode to a first preset threshold" in the above step, the method may further include:
acquiring an induction signal received by the receiving electrode in an induction electric field;
calculating the number of preset waveforms in the induction signal;
and controlling the display screen to be off or on according to the number.
In this embodiment, when the voltage of the transmitting electrode is increased to the first preset threshold, the induced electric field is formed above the display screen, the induced signal is mainly formed in the induced electric field by a signal wave (a transmitting signal) transmitted by the transmitting electrode, the transmitting signal may be a periodically changing wave signal, the waveform of the wave signal may be rectangular, triangular or other shapes, and the like, and under a normal condition, the waveform of the induced signal is consistent with the waveform of the transmitting signal. The transmitting electrodes and the receiving electrodes are usually arranged oppositely, the number and the installation position of the transmitting electrodes and the receiving electrodes can be determined according to actual requirements, the number determines the number of signal waves transmitted at a single moment, and the installation position determines the position of an induced electric field.
It should be noted that the sensing signal may be a wave signal received within a specified time period, or may be a wave signal received at a specified time, and the preset waveform may be set to a certain section of waveform or a certain point within a complete cycle in the sensing signal, and may be specifically determined according to an actual requirement, for example, when the sensing signal is a wave signal within a specified time period, the preset waveform may be a line segment, and when the sensing signal is a wave signal at a specified time, the preset waveform may be a point whose amplitude is not 0.
For example, the step of "controlling the display screen to turn off or turn on according to the number" may specifically include:
judging whether the number is smaller than a second preset threshold value;
if so, controlling the display screen to be off;
if not, controlling the display screen to light.
In this embodiment, ideally, the number of waves in the transmission signal is the same as the number of waves in the sensing signal. Referring to fig. 3 and 4, since the human body is conductive, if the human body is located in the induced electric field (i.e. close to the screen), a part of the induced signal is guided to the ground, so that the number of the waves in the induced signal is smaller than the number of the waves in the transmitted signal, and considering that when a human body part (such as a human face) is close to the screen, a certain approaching area exists, so that if the human body is located in the induced electric field, a minimum difference value exists between the number of the waves in the induced signal and the number of the waves in the transmitted signal, and the closer the human body part is to the screen, the larger the approaching area is, the larger the difference value is. The second predetermined threshold may be determined according to the number of electrodes in the transmitting electrode or the receiving electrode and the minimum difference, that is, the second predetermined threshold may be determined according to the number of waves in the transmitting signal and the minimum difference, which may be a difference between the number of waves in the transmitting signal and the minimum difference, for example, if the minimum difference is 50, when the number of waves in the transmitting signal is 200, the second predetermined threshold may be 150.
Specifically, when the total number of the preset waveforms is detected to be smaller than the second preset threshold, it is indicated that the number of the sensing signals guided away by the human body is large, the human body is close to the display screen, for example, a user is making a call through a mobile phone, and at this time, in order to avoid misoperation caused by the fact that the user touches the display screen with a finger, the backlight of the display screen can be turned off, so that touch sensing of the display screen is stopped. When the total number of the preset waveforms is detected to be larger than or equal to the second preset threshold value, it is indicated that the induction signals guided away by the human body are less, and the human body and the display screen are in a far-away state, for example, a user browses new short messages or checks time in the process of making a call, at the moment, in order to facilitate the operation of the user, a backlight lamp of the display screen can be lightened, and touch induction of the display screen is started.
It should be noted that, the control method for turning off and turning on the display screen provided by this embodiment needs to set a screen opening and a proximity sensor (for example, an infrared sensor) to realize proximity and distance determination, so as to control the turning off and turning on of the display screen, and can be realized through software control.
As can be seen from the above, the control method of the display screen provided in this embodiment is applied to an electronic device including a display screen, where the working mode of the display screen includes a suspension mode and a contact mode, and the current working mode of the display screen is obtained, and a mode switching signal is generated according to the current working mode, and then according to the mode switching signal, the working mode of the display screen is switched from the current working mode to another working mode, so that the display screen can be freely switched between contact touch and non-contact touch without setting a sensor and a screen opening, and further, automatic control of screen turn-off and screen turn-on of the display screen is realized.
