Referring to fig. 5, fig. 5 is a schematic flowchart illustrating a control method of an electronic device according to an embodiment of the present disclosure. The method is applied to an electronic device 100 with a display screen 20, the display screen 20 further comprises a first touch area 21 and a second touch area 22, the first touch area 21 is located at the top end of the display screen 20, and the method comprises the following steps:
When the electronic device is detected to enter a call state, touch sensitivity of the first touch area is adjusted to enable the first touch area to be in a floating touch state.
The display screen 20 may be a capacitive touch screen, and two types of capacitors, i.e., a mutual capacitor and a self capacitor, may be disposed on the capacitive touch screen. When the mutual capacitance is detected, the transverse electrodes sequentially send out excitation signals, the longitudinal electrodes simultaneously receive signals to obtain the capacitance values of the intersection points of all the transverse electrodes and the longitudinal electrodes, namely the capacitance values of the two-dimensional plane of the whole touch screen, and the coordinates of each touch point can be calculated according to the two-dimensional capacitance variation data of the touch screen, so that the real coordinates of each touch point can be calculated even if a plurality of touch points exist on the screen. Mutual capacitance can be used to realize multi-touch detection, but the electric field of mutual capacitance is so small that the signal strength is so low that very weak signals cannot be sensed, so when a sensing object (such as a user's finger) hovers on the screen, the mutual capacitance cannot sense signals. The self-capacitance is that the horizontal and vertical electrode arrays are made of ITO on the surface of the glass, the horizontal and vertical electrodes respectively form capacitance with the ground, namely the self-capacitance is the capacitance of the electrode to the ground; when a finger touches the capacitive screen, the capacitance of the finger is superposed on the capacitance of the screen body, so that the capacitance of the screen body is increased; during touch detection, the self-capacitance sequentially and respectively detects the transverse electrode array and the longitudinal electrode array, respectively determines a transverse coordinate and a longitudinal coordinate according to the change of capacitance before and after touch, and then combines the transverse coordinate and the longitudinal coordinate into a planar touch coordinate; the scanning mode of the self-capacitance is equivalent to projecting touch points on the touch screen to the X-axis direction and the Y-axis direction respectively, then calculating coordinates in the X-axis direction and the Y-axis direction respectively, and finally combining the coordinates into the coordinates of the touch points. The self-capacitance can generate a signal stronger than the mutual capacitance, and can be used for detecting a sensing object farther away, such as a sensing distance range of a finger up to 20 mm.
The display screen 20 further includes a first touch area 21 and a second touch area 22, the first touch area 21 is located at the top end of the display screen 20, and the second touch area 22 is a touch area excluding the first touch area 21 on the display screen 20.
In some embodiments, two types of capacitances are disposed on the first touch area 21, including a mutual capacitance and a self capacitance; the second touch area 22 has a capacitance, including a mutual capacitance, disposed thereon. For example, after the display screen 20 is powered on, the mutual capacitance between the first touch area 21 and the second touch area 22 is always in an active state, and the self capacitance of the first touch area 21 may be in an active state or a sleep state. For example, the self-capacitance of the first touch area 21 is generally in a sleep state, when it is detected that the electronic device 100 enters the call state, the self-capacitance of the first touch area 21 starts to be powered on, and the state is changed from the sleep state to an operating state, and the strength of the electric field signal of the self-capacitance of the first touch area 21 is enhanced to make the first touch area 21 in a floating touch state. Further, when it is detected that the electronic device 100 exits the call state, the strength of the electric field signal of the self-capacitance of the first touch area 21 is reduced or the self-capacitance of the first touch area 21 is turned off to make the first touch area 21 in the contact touch state.
In some embodiments, two capacitors are simultaneously disposed on the full screen of the display screen 20, that is, a mutual capacitor and a self capacitor are simultaneously disposed on the first touch area 21 and the second touch area 22. For example, after the display screen 20 is powered on, the mutual capacitance and the self-capacitance of the first touch area 21 and the second touch area 22 are always in the working state, and when it is detected that the electronic device 100 enters the call state, the self-capacitance of the second touch area 22 is turned off, so that only the self-capacitance of the first touch area 21 is kept in the working state, and the strength of the electric field signal of the self-capacitance of the first touch area 21 is enhanced to make the first touch area 21 in the floating touch state, and the second touch area 22 in the contact touch state.
In some embodiments, the touch sensitivity of the first touch area may be individually adjusted high, and the touch sensitivity of the second touch area may be kept unchanged.
For example, a mutual capacitance and a self capacitance are provided on the first touch area 21, and only a mutual capacitance is provided on the second touch area 22, for example, after the display screen 20 is powered on, the mutual capacitance between the first touch area 21 and the second touch area 22 is always in an operating state, and the self capacitance of the first touch area 21 may be in an operating state or a sleep state. For example, the self-capacitance of the first touch area 21 is generally in a sleep state, when it is detected that the electronic device 100 enters a call state, the self-capacitance of the first touch area 21 starts to be powered on, and is switched to an operating state from the sleep state, and the strength of the electric field signal of the self-capacitance of the first touch area 21 is enhanced to make the first touch area 21 in a floating touch state, and the strength of the electric field signal of the mutual capacitance of the second touch area 22 is kept unchanged.
For example, after the display screen 20 is powered on, the mutual capacitance and the self-capacitance of the first touch area 21 and the second touch area 22 are always in an operating state, and when it is detected that the electronic device 100 enters a call state, the strength of the electric field signal of the self-capacitance of the first touch area 21 is enhanced to make the first touch area 21 in a floating touch state, and the strength of the electric field signal of the mutual capacitance and the self-capacitance of the second touch area 22 is kept unchanged.
In some embodiments, the touch sensitivity of the first touch area may be adjusted up and the sensitivity of the second touch area may be adjusted down.
For example, a mutual capacitance and a self capacitance are provided on the first touch area 21, and only a mutual capacitance is provided on the second touch area 22, for example, after the display screen 20 is powered on, the mutual capacitance between the first touch area 21 and the second touch area 22 is always in an operating state, and the self capacitance of the first touch area 21 may be in an operating state or a sleep state. For example, the self-capacitance of the first touch area 21 is generally in a sleep state, when it is detected that the electronic device 100 enters a call state, the self-capacitance of the first touch area 21 starts to be powered on, and is switched to an operating state from the sleep state, and the electric field signal strength of the self-capacitance of the first touch area 21 is enhanced to make the first touch area 21 in a floating touch state, and the electric field signal strength of the mutual capacitance of the second touch area 22 is reduced.
For example, after the display screen 20 is powered on, the mutual capacitance and the self-capacitance of the first touch area 21 and the second touch area 22 are always in an operating state, and when it is detected that the electronic device 100 enters a call state, the strength of the electric field signal of the self-capacitance of the first touch area 21 is enhanced to make the first touch area 21 in a floating touch state, and the strength of the electric field signal of the mutual capacitance and the self-capacitance of the second touch area 22 are reduced. Or when the electronic device 100 is detected to enter the call state, the electric field signal strength of the self-capacitance of the first touch area 21 is enhanced to make the first touch area 21 in the floating touch state, and the self-capacitance of the second touch area 22 is turned off, until the electronic device 100 exits the call state, the self-capacitance of the second touch area 22 is turned on again.
And 102, detecting a distance state between a user and the first touch area through the first touch area in the floating touch state.
After the first touch area 21 enters the floating touch state, the distance state between the user and the first touch area 21 can be detected through the first touch area 21 in the floating touch state. For example, the distance state between the face or ear of the user and the first touch region 21 is detected by the first touch region 21 in the floating touch state. For example, the distance state may include a proximity state in which the face or ear of the user is detected to be in proximity to the first touch region 21. The distance state may also comprise a far state, i.e. the face or ear of the user is detected to be far away from the first touch area 21.
And 103, responding to the distance state, and controlling the electronic device to realize a control function corresponding to the distance state.
In some embodiments, the distance state comprises a proximity state, wherein the controlling the electronic device to implement the control function corresponding to the distance state in response to the distance state comprises:
and responding to the approaching state, and controlling the electronic device to close the display screen in the call process.
For example, taking a mobile phone as an example, when a user holds the mobile phone to perform a call, and the mobile phone is close to the face of the user, the display screen of the mobile phone can be directly closed in the call process in response to the proximity state, so as to save power.
For example, when the approaching state occurs, the display screen may be controlled to be locked first, and the display screen may be closed when the departing state does not occur within a few seconds after the locking of the display screen, and may be opened when the departing state occurs. The time for closing the display screen is adjusted to the time for locking the display screen for several seconds, so that the frequent switching of the screen lightening and the screen extinguishing of the display screen caused by the too frequent change of the approaching state and the far state is prevented, and the service life of the display screen is protected to a certain extent.
In some embodiments, the distance state comprises a far state, wherein the controlling the electronic device to implement the control function corresponding to the distance state in response to the distance state comprises:
and responding to the far-away state, and controlling the electronic device to open the display screen after the call is finished.
For example, taking a mobile phone as an example, when a user holds the mobile phone to perform a call, and after the call is ended and the mobile phone is far away from the face of the user, the mobile phone is controlled to open the display screen after the call is ended in response to the far-away state, so that the mobile phone is convenient for the user to use.
For example, when a far-away state occurs during a call, the display screen may be controlled to be bright but still be locked, and the display screen may be unlocked when the near state does not occur within a few seconds after the bright, so that the user may use other functions of the mobile phone during the call, such as searching for a contact phone.
All the above technical solutions can be combined arbitrarily to form the optional embodiments of the present application, and are not described herein again.
The electronic device with the display screen provided by the embodiment of the application comprises a first touch area and a second touch area, wherein the first touch area is located at the top end of the display screen, the first touch area is in a suspension touch state by adjusting the touch sensitivity of the first touch area of the display screen, the distance state between a user and the first touch area is detected through the first touch area in the suspension touch state, and the electronic device is controlled to realize a control function corresponding to the distance state in response to the distance state. The electronic device of this application embodiment is when realizing being close the function, touch sensitivity through the fixed area on adjustment display screen top is in order to realize the suspension touch-control, utilizes the touch-control signal of display screen itself to realize being close the function to improve the accuracy that electronic device control display screen put out the screen or bright screen, can realize being close the function through utilizing the display screen under the condition of leaving out proximity sensor, can improve compact structure nature, practice thrift design cost.

Mutual capacitance can be used to realize multi-touch detection, but the electric field of mutual capacitance is so small that the signal strength is so low that very weak signals cannot be sensed, so when a sensing object (such as a user's finger) hovers on the screen, the mutual capacitance cannot sense signals. The self-capacitance is that the horizontal and vertical electrode arrays are made of ITO on the surface of the glass, the horizontal and vertical electrodes respectively form capacitance with the ground, namely the self-capacitance is the capacitance of the electrode to the ground; when a finger touches the capacitive screen, the capacitance of the finger is superposed on the capacitance of the screen body, so that the capacitance of the screen body is increased; during touch detection, the self-capacitance sequentially and respectively detects the transverse electrode array and the longitudinal electrode array, respectively determines a transverse coordinate and a longitudinal coordinate according to the change of capacitance before and after touch, and then combines the transverse coordinate and the longitudinal coordinate into a planar touch coordinate; the scanning mode of the self-capacitance is equivalent to projecting touch points on the touch screen to the X-axis direction and the Y-axis direction respectively, then calculating coordinates in the X-axis direction and the Y-axis direction respectively, and finally combining the coordinates into the coordinates of the touch points. The self-capacitance can generate a signal stronger than the mutual capacitance, and can be used for detecting a sensing object farther away, such as a sensing distance range of a finger up to 20 mm.

For example, after the display screen 20 is powered on, the mutual capacitance between the first touch area 21 and the second touch area 22 is always in an active state, and the self capacitance of the first touch area 21 may be in an active state or a sleep state. For example, the self-capacitance of the first touch area 21 is generally in a sleep state, when it is detected that the electronic device 100 enters the call state, the control circuit 31 controls the self-capacitance of the first touch area 21 to start to be powered on, and switches from the sleep state to an operating state, and increases the strength of the electric field signal of the self-capacitance of the first touch area 21 to make the first touch area 21 in a floating touch state. Further, when the control circuit 31 detects that the electronic device 100 exits the call state, the control circuit 31 decreases the strength of the electric field signal of the self-capacitance of the first touch area 21 or turns off the self-capacitance of the first touch area 21 to make the first touch area 21 in the contact touch state.
In some embodiments, two capacitors are simultaneously disposed on the full screen of the display screen 20, that is, a mutual capacitor and a self capacitor are simultaneously disposed on the first touch area 21 and the second touch area 22. For example, after the display screen 20 is powered on, the mutual capacitance and the self-capacitance of the first touch area 21 and the second touch area 22 are always in the working state, when the control circuit 31 detects that the electronic device 100 enters the call state, the control circuit 31 turns off the self-capacitance of the second touch area 22, so that only the self-capacitance of the first touch area 21 is kept in the working state, and the strength of the electric field signal of the self-capacitance of the first touch area 21 is enhanced to make the first touch area 21 in the floating touch state, and the second touch area 22 in the contact touch state.
In some embodiments, the control circuit 31 can individually adjust the touch sensitivity of the first touch area 21 high and keep the touch sensitivity of the second touch area constant.
For example, a mutual capacitance and a self capacitance are provided on the first touch area 21, and only a mutual capacitance is provided on the second touch area 22, for example, after the display screen 20 is powered on, the mutual capacitance between the first touch area 21 and the second touch area 22 is always in an operating state, and the self capacitance of the first touch area 21 may be in an operating state or a sleep state. For example, the self-capacitance of the first touch area 21 is generally in a sleep state, when the control circuit 31 detects that the electronic device 100 enters a call state, the control circuit 31 controls the self-capacitance of the first touch area 21 to start to be powered on, and switches from the sleep state to an operating state, and increases the electric field signal strength of the self-capacitance of the first touch area 21 to make the first touch area 21 in a floating touch state, and keeps the electric field signal strength of the mutual capacitance of the second touch area 22 unchanged.
For example, after the display screen 20 is powered on, the mutual capacitance and the self-capacitance of the first touch area 21 and the second touch area 22 are always in an operating state, and when the control circuit 31 detects that the electronic device 100 enters a call state, the control circuit 31 enhances the electric field signal strength of the self-capacitance of the first touch area 21 to make the first touch area 21 in a floating touch state, and keeps the electric field signal strengths of the mutual capacitance and the self-capacitance of the second touch area 22 unchanged.
In some embodiments, the control circuit 31 can adjust the touch sensitivity of the first touch area 21 up and adjust the sensitivity of the second touch area 22 down.
For example, a mutual capacitance and a self capacitance are provided on the first touch area 21, and only a mutual capacitance is provided on the second touch area 22, for example, after the display screen 20 is powered on, the mutual capacitance between the first touch area 21 and the second touch area 22 is always in an operating state, and the self capacitance of the first touch area 21 may be in an operating state or a sleep state. For example, the self-capacitance of the first touch area 21 is generally in a sleep state, when the control circuit 31 detects that the electronic device 100 enters a call state, the control circuit 31 controls the self-capacitance of the first touch area 21 to start to be powered on, and switches from the sleep state to an operating state, and increases the electric field signal strength of the self-capacitance of the first touch area 21 to make the first touch area 21 in a floating touch state, and decreases the electric field signal strength of the mutual capacitance of the second touch area 22.
For example, after the display screen 20 is powered on, the mutual capacitance and the self-capacitance of the first touch area 21 and the second touch area 22 are always in an operating state, and when the control circuit 31 detects that the electronic device 100 enters a call state, the control circuit 31 increases the electric field signal strength of the self-capacitance of the first touch area 21 to make the first touch area 21 in a floating touch state, and decreases the mutual capacitance and the electric field signal strength of the self-capacitance of the second touch area 22. Or when the control circuit 31 detects that the electronic device 100 enters the call state, the control circuit 31 increases the electric field signal strength of the self-capacitance of the first touch area 21 to make the first touch area 21 in the floating touch state, and turns off the self-capacitance of the second touch area 22 until the electronic device 100 exits the call state, and then turns on the self-capacitance of the second touch area 22 again.
After the first touch area 21 enters the floating touch state, the control circuit 31 can detect the distance state between the user and the first touch area 21 through the first touch area 21 in the floating touch state. For example, the control circuit 31 detects a distance state between the face or ear of the user and the first touch region 21 through the first touch region 21 in the floating touch state. For example, the distance state may include a proximity state in which the face or ear of the user is detected to be in proximity to the first touch region 21. The distance state may also comprise a far state, i.e. the face or ear of the user is detected to be far away from the first touch area 21.
In some embodiments, the distance state includes a proximity state, wherein the control circuit 31 is configured to control the electronic device 100 to turn off the display screen 20 during a call in response to the proximity state.
For example, taking a mobile phone as an example, when a user holds the mobile phone to perform a call, and the mobile phone is close to the face of the user, the display screen of the mobile phone can be directly closed in the call process in response to the approaching state, so as to save power.
For example, when the approaching state occurs, the display screen may be controlled to be locked first, and the display screen may be closed when the departing state does not occur within a few seconds after the locking of the display screen, and may be opened when the departing state occurs. The time for closing the display screen is adjusted to the time for locking the display screen for several seconds, so that the frequent switching of the screen lightening and the screen extinguishing of the display screen caused by the too frequent change of the approaching state and the far state is prevented, and the service life of the display screen is protected to a certain extent.
In some embodiments, the distance status includes a far-away status, wherein the control circuit 31 is configured to control the electronic device 100 to open the display screen 20 after the call is ended in response to the far-away status.
For example, taking a mobile phone as an example, when a user holds the mobile phone to perform a call, and after the call is ended and the mobile phone is far away from the face of the user, the mobile phone is controlled to open the display screen after the call is ended in response to the far-away state, so that the mobile phone is convenient for the user to use.
For example, when a far-away state occurs during a call, the display screen may be controlled to be bright but still be locked, and the display screen may be unlocked when the near state does not occur within a few seconds after the bright, so that the user may use other functions of the mobile phone during the call, such as searching for a contact phone.
The electronic device 100 provided by the embodiment of the application includes a display screen 20 and a control circuit 31, where the display screen 20 includes a first touch area 21 and a second touch area 22, the first touch area 21 is located at the top end of the display screen 20, the control circuit 31 makes the first touch area 21 be in a floating touch state by adjusting the touch sensitivity of the first touch area 21 of the display screen 20, detects a distance state between a user and the first touch area 21 through the first touch area 21 in the floating touch state, and controls the electronic device 100 to implement a control function corresponding to the distance state in response to the distance state. When the electronic device 100 of the embodiment of the application realizes the proximity function, the touch sensitivity of the fixed area 21 on the top end of the display screen 20 is adjusted to realize suspension touch control, the proximity function is realized by using the touch signal of the display screen, the accuracy of controlling the display screen to be turned off or turned on by the electronic device is improved, the proximity function of the proximity sensor can be realized by using the display screen under the condition of saving the proximity sensor, the structure is compact, and the design cost is saved.
