Detailed Description
The core of the invention is to provide a touch screen display control method and a touch screen display control system for a mobile terminal, which ensure the normal operation of a user on the mobile terminal when the mobile terminal and external communication equipment perform NFC data interaction.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
In the following description, specific details are set forth in order to provide a thorough understanding of the present invention. The invention can be implemented in a number of ways different from those described herein and similar generalizations can be made by those skilled in the art without departing from the spirit of the invention. The invention is therefore not limited to the specific implementations disclosed below.
Referring to fig. 1, fig. 1 is a flowchart illustrating a touch screen display control method for a mobile terminal according to an embodiment of the present invention.
A specific embodiment of the present invention provides a touch screen display control method for a mobile terminal, including:
s11: the method comprises the steps of obtaining the touch interference range of a magnetic field generated by an NFC coil of the mobile terminal to a touch screen of the mobile terminal when the mobile terminal and external communication equipment perform NFC interaction, and defining the touch interference range as a touch interference area.
S12: and reducing the display area of the touch screen, wherein no overlapping area exists between the reduced current display area and the touch interference area.
Taking a mobile terminal as an example of a smart phone, when a user normally operates the smart phone, the smart phone is normally displayed in a full screen mode. When the rear cover of the mobile phone is a metal shell, the mobile phone performs NFC interaction with external communication equipment through one side of the touch screen. If the external communication device is an IC card, the IC card needs to be moved to the screen of the mobile phone so that the IC card can complete NFC interaction with the mobile phone. And when communication equipment such as IC-cards and the like and the mobile terminal carry out NFC interaction, the NFC coil of the mobile terminal can generate a certain magnetic field, the magnetic field generates interference on the touch screen within a certain range, the touch screen is disturbed in touch operation and the like, and manual operation of a user can be influenced. Therefore, in the embodiment, the interference range of the magnetic field generated by the NFC coil to the touch screen during NFC interaction is firstly acquired, and then the display area of the touch screen is reduced, so that the display area of the touch screen is separated from the interference range, and thus the magnetic field of the NFC coil does not interfere with the operation interface of the touch screen, thereby ensuring normal operation of the user on the mobile terminal when the mobile terminal and the external communication device perform NFC data interaction. If when the external communication equipment is an IC card, the effective touch range is correspondingly reduced due to the reduction of the display area, and the touch operation range is reduced, namely, the touch failure of the part of the NFC coil which affects the touch is avoided, and the touch operation range and the effectively touched display area are not interfered with each other, so that a user can normally operate the touch screen to write, recharge, transfer or pay the IC card and other communication equipment.
It should be noted that, in this document, the "display area" refers to an effective touch area of the mobile terminal, that is, an area where a user can manually perform a touch operation.
On the basis of the above embodiment, acquiring a touch interference range of a magnetic field generated by an NFC coil of the mobile terminal to a touch screen of the mobile terminal when the mobile terminal and an external communication device perform NFC interaction, and defining the touch interference range as a touch interference area includes: acquiring a magnetic field intensity signal of a magnetic field generated by an NFC coil of the mobile terminal when the mobile terminal and external communication equipment perform NFC interaction; and positioning the NFC coil according to the magnetic field intensity signal, judging the touch interference range of the magnetic field to the touch screen of the mobile terminal, and defining the touch screen area corresponding to the touch interference range of the magnetic field to the touch screen of the mobile terminal as a touch interference area.
In the present embodiment, a method of acquiring a touch interference area is specifically described. When the external communication equipment and the mobile terminal perform the NFC interaction, the relative positions of the external communication equipment and the mobile terminal are random, so that the magnetic fields generated by the NFC coil of the mobile terminal are different during each interaction, and the touch interference areas are different under the normal condition. In this embodiment, by obtaining a magnetic field intensity signal of a magnetic field generated by a current NFC coil, a position of the NFC coil can be located according to the magnitude of the magnetic field intensity signal, and a touch interference range is determined, so as to define a touch interference area during current NFC interaction.
In the present embodiment, after the touch interference area is determined, the display area of the touch screen may be controlled to be adaptively reduced as long as the display area and the touch interference area do not overlap each other.
It should be noted that, in this embodiment, it is only preferable to determine the touch interference range by acquiring the magnetic field strength signal of the NFC coil, and the touch interference range may also be acquired by other methods; or directly judging the maximum interference range of the NFC coil to the touch screen under the common condition, and controlling the display area of the touch screen to be out of the maximum interference range when NFC interaction is carried out each time.
Further, in an embodiment of the present invention, acquiring a magnetic field strength signal of a magnetic field generated by an NFC coil of a mobile terminal when the mobile terminal and an external communication device perform NFC interaction includes: acquiring an NFC starting signal of the mobile terminal; judging whether the mobile terminal is in an NFC interaction state with external communication equipment or not; and if so, acquiring a magnetic field intensity signal of a magnetic field generated by the NFC coil of the mobile terminal.
The magnetic field intensity signal of the NFC coil of the mobile terminal is acquired in real time and processed, so that corresponding hardware for realizing the method is always in a standby state, and meaningless power consumption is caused. In the embodiment, the magnetic field intensity signal is acquired only when the NFC starting signal of the mobile terminal is acquired and the NFC interaction with the external communication device is determined. That is, when the mobile terminal starts the NFC function, the flow of the touch screen display control method provided in each of the above embodiments is triggered, so that power consumption can be greatly reduced.
In one embodiment of the present invention, reducing a display area of a touch screen, where there is no overlapping area between a reduced current display area and a touch interference area, includes: acquiring a touch normal area without an overlapped area in the touch screen and the touch interference area according to the touch interference area; and controlling the display area of the touch screen to be reduced to a preset position of the touch normal area.
In this embodiment, the display area of the touch screen may be controlled to be reduced to a preset position of the normal display area of the touch screen according to a preset program or the like. For example, when the NFC coil is located at the upper portion of the mobile terminal, the reduced current display area is close to the lower right side of the entire touch screen.
In this embodiment, after the display area is reduced, the position of the display area on the touch screen may be changed according to the operation of the user on the touch screen, for example, when the display area is reduced to the lower right side of the touch screen, and when the user clicks a blank area of the display area (i.e., an area without any application in the display area), the display area moves correspondingly with the movement of the user's finger until the user's finger leaves the touch screen.
Further, the method further includes, after the display area of the touch screen is reduced and there is no overlapping area between the reduced current display area and the touch interference area: judging whether the mobile terminal and external communication equipment are disconnected from NFC interaction or not; and if so, controlling the touch screen to restore the full-screen display.
In the embodiment, when the mobile terminal is disconnected from the NFC interaction with the external communication device, full-screen display is resumed, so that the mobile terminal resumes a normal use state, and a user can conveniently operate and use the mobile terminal.
Referring to fig. 2, fig. 2 is a schematic structural diagram of a touch screen display control system for a mobile terminal according to an embodiment of the present invention.
Accordingly, an embodiment of the present invention further provides a touch screen display control system for a mobile terminal, including: the system comprises an acquisition module 1, a processing module and a display module, wherein the acquisition module 1 is used for acquiring the touch interference range of a touch screen of the mobile terminal caused by a magnetic field generated by an NFC coil of the mobile terminal when the mobile terminal and external communication equipment perform NFC interaction, and defining the touch interference range as a touch interference area; and the control module 2 is used for reducing the display area of the touch screen, and the reduced current display area and the touch interference area do not have an overlapping area.
In this embodiment, when the mobile terminal needs to perform NFC interaction with an external communication device, the interference range of the magnetic field generated by the NFC coil to the touch screen is acquired through the acquisition module, and then the display area of the touch screen is reduced through the control module, so that the display area of the touch screen is separated from the interference range, and thus the magnetic field of the NFC coil does not generate interference influence on the operation interface of the touch screen, and normal operation of the user on the mobile terminal is ensured when the mobile terminal performs NFC data interaction with the external communication device.
Referring to fig. 3, fig. 3 is a schematic diagram of a touch screen display control state of a mobile terminal using a touch screen display control system for the mobile terminal according to an embodiment of the present invention.
In one embodiment of the present invention, the obtaining module includes: the magnetic sensing unit is used for acquiring a magnetic field intensity signal of a magnetic field generated by an NFC coil of the mobile terminal when the mobile terminal and external communication equipment perform NFC interaction; and the processing unit is used for positioning the NFC coil according to the magnetic field intensity signal, judging the touch interference range of the magnetic field to the touch screen of the mobile terminal, and defining the touch screen area corresponding to the touch interference range of the magnetic field to the touch screen of the mobile terminal as a touch interference area.
In the present embodiment, as shown in fig. 3, a mobile phone will be described as an example of a mobile terminal. A magnetic sensing unit 11 is arranged in the mobile terminal to detect a magnetic field intensity signal of a magnetic field generated by an NFC coil of the mobile terminal when the mobile terminal and external communication equipment perform NFC interaction. In fig. 3, the area 31 is a touch interference area of the NFC coil on the touch screen, and the area 32 is a reduced current display area. Since a magnetic sensor is installed in a large number of mobile terminals such as mobile phones, and an inherent magnetic sensor can be used as a magnetic sensing unit, it is not necessary to install the magnetic sensor separately, and the magnetic sensing unit can be installed separately as needed to obtain a magnetic field intensity signal of the NFC coil. The processing unit in this embodiment may directly adopt the processor of the mobile terminal or separately provide a processor.
When the external communication equipment and the mobile terminal perform the NFC interaction, the relative positions of the external communication equipment and the mobile terminal are random, so that the magnetic fields generated by the NFC coil of the mobile terminal are different during each interaction, and the touch interference areas are different under the normal condition. In this embodiment, by obtaining a magnetic field intensity signal of a magnetic field generated by a current NFC coil, a position of the NFC coil can be located according to the magnitude of the magnetic field intensity signal, and a touch interference range is determined, so as to define a touch interference area during current NFC interaction.
In one embodiment of the present invention, a magnetic force sensing unit includes: the first acquiring subunit is used for acquiring an NFC starting signal of the mobile terminal; the judging subunit is used for judging whether the mobile terminal is in an NFC interaction state with external communication equipment; and the second acquiring subunit is used for acquiring a magnetic field intensity signal of a magnetic field generated by the NFC coil of the mobile terminal when the judging subunit judges that the mobile terminal and the external communication equipment are in the NFC interaction state.
In this embodiment, the magnetic sensing unit is configured to enable other functional modules of the entire display control system to be in a standby state, and only when the NFC start signal of the mobile terminal is obtained and the NFC interaction with the external communication device is determined, the magnetic field strength signal is obtained, so as to trigger the operation of each functional module in the system. Namely, when the mobile terminal is in a bright screen state, the NFC function is started, the data or the WLAN is started, the real-time interaction application is started, when the external communication equipment moves to the position range of the NFC function part of the touch screen of the mobile terminal, the real-time interaction is carried out, and at the moment, the magnetic field intensity signal of the NFC coil is acquired.
In one embodiment of the invention, the control module comprises: the acquisition unit is used for acquiring a touch normal area without an overlapped area in the touch screen and the touch interference area according to the touch interference area; and the control unit is used for controlling the display area of the touch screen to be reduced to a preset position of the touch normal area.
In this embodiment, the control module may acquire information of an entire touch area of a touch screen of the mobile terminal, for example, position information of the entire touch area in a dot matrix manner. When the magnetic field intensity signal of the NFC coil is acquired, the touch interference area and the whole touch area can be compared, so that a normal touch area is obtained, and then the display area of the touch screen is controlled to be reduced, so that the whole display interface is located in the normal touch area.
In one embodiment of the present invention, the display control system further includes: and the judging module is used for judging whether the mobile terminal and the external communication equipment are disconnected from NFC interaction. And the execution module is used for controlling the touch screen to restore the full screen display when the judgment module judges that the NFC interaction between the mobile terminal and the external communication equipment is disconnected.
In the embodiment, when the mobile terminal is disconnected from the NFC interaction with the external communication device, full-screen display is resumed, so that the mobile terminal resumes a normal use state, and a user can conveniently operate and use the mobile terminal.
In summary, according to the touch screen display control method and system for the mobile terminal provided by the present invention, when the mobile terminal needs to perform NFC interaction with an external communication device, firstly, an interference range of a magnetic field generated by an NFC coil to the touch screen during the NFC interaction is obtained, and then, a display area of the touch screen is reduced, so that the display area of the touch screen is separated from the interference range, and thus, the magnetic field of the NFC coil does not generate an interference influence on an operation interface of the touch screen, thereby ensuring normal operation of a user on the mobile terminal when the mobile terminal performs NFC data interaction with the external communication device.
