Background technique

With the development of information technology, mobile terminals such as mobile phones have become indispensable electronic products for people's life and work.

At present, the design of all-metal shells for mobile terminals such as mobile phones is becoming more and more common. Metal shells can improve the safety of mobile terminals and are less likely to be greatly damaged when they are dropped or hit. However, since metal has a shielding effect on electrical communication signals, some communication components of a mobile terminal with an all-metal casing cannot perform data interaction with external devices through the metal casing. NFC (near-field communication technology) devices have been widely used in mobile terminals such as mobile phones, which greatly facilitate people's lives. NFC devices perform data interaction with external communication devices through their own NFC coils. Due to the full metal shell It also has a shielding effect on the NFC device.

However, when the NFC device interacts with external communication equipment, the screen area of the mobile terminal between the NFC coil and the external communication equipment will be disturbed by the magnetic field generated when the two interact. , the operation of the disturbed area of the touch screen will be greatly affected, so that the user cannot normally operate the mobile terminal.

Therefore, how to ensure the normal operation of the mobile terminal by the user when the mobile terminal interacts with the external communication device for NFC data is a technical problem currently to be solved by those skilled in the art.

detailed description

The core of the present invention is to provide a touch screen display control method and system for a mobile terminal, which ensures the normal operation of the mobile terminal by the user when the mobile terminal interacts with external communication devices for NFC data.

In order to make the above objects, features and advantages of the present invention more comprehensible, the specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

In the following description, specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways than those described here, and those skilled in the art can make similar extensions without departing from the connotation of the present invention. Accordingly, the invention is not limited to the specific implementations disclosed below.

Please refer to FIG. 1 , which is a flow chart of a touch screen display control method for a mobile terminal provided by a specific 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: Obtain the touch interference range of the touch screen of the mobile terminal by the magnetic field generated by the NFC coil of the mobile terminal when the mobile terminal interacts with the external communication device through NFC, and define it as a touch interference area.

S12: Reduce the display area of the touch screen, and there is no overlapping area between the reduced current display area and the touch interference area.

Taking the mobile terminal as an example of a smart phone, when the user normally operates the mobile phone, usually the smart phone is displayed in full screen. Because when the back cover of the mobile phone is a metal shell, the mobile phone performs NFC interaction with the external communication device 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 the NFC interaction with the mobile phone. When communication devices such as IC cards interact with the mobile terminal through NFC, the NFC coil of the mobile terminal will generate a certain magnetic field, which will interfere with the touch screen within a certain range, causing random touch operations on the touch screen, etc. will be affected. Therefore, in this embodiment, first obtain the interference range of the magnetic field generated by the NFC coil to the touch screen during NFC interaction, and then reduce the display area of the touch screen so that the display area of the touch screen is out of the interference range, so that the magnetic field of the NFC coil will not Interference affects the touch screen operation interface, thereby ensuring the normal operation of the mobile terminal by the user when the mobile terminal and the external communication device perform NFC data interaction. For example, when the external communication device is an IC card, due to the narrowing of the display area, the effective touch range is correspondingly reduced, which reduces the touch operation range, that is to say, the touch effect of the NFC coil on the touch is invalid, which is different from the effective touch display area. Interference, the user can normally operate the touch screen to write cards, recharge, transfer or pay for communication devices such as IC cards.

It should be noted that the "display area" herein refers to the effective touch area of the mobile terminal, that is, the area where the user can artificially perform touch operations.

On the basis of the above-mentioned embodiments, when the mobile terminal interacts with external communication devices through NFC, the touch interference range of the magnetic field generated by the NFC coil of the mobile terminal on the touch screen of the mobile terminal is obtained, and is defined as the touch interference area, including: obtaining the mobile terminal and The magnetic field strength signal of the magnetic field generated by the NFC coil of the mobile terminal when the external communication device performs NFC interaction; locate the NFC coil according to the magnetic field strength signal, and determine the touch interference range of the magnetic field to the touch screen of the mobile terminal, and define the impact of the magnetic field on the touch screen of the mobile terminal The touch screen area corresponding to the touch interference range is the touch interference area.

In this embodiment, the manner of acquiring the touch interference area is specifically described. When the external communication device and the mobile terminal perform NFC interaction, since the relative position of the external communication device and the mobile terminal is random, the magnetic field generated by the NFC coil of the mobile terminal is different for each interaction, so the touch interference area is usually The case is different. In this embodiment, by acquiring the magnetic field strength signal of the magnetic field generated by the current NFC coil, the position of the NFC coil can be located according to the magnitude of the magnetic field strength signal, and the touch interference range can be determined to define the current touch interference during NFC interaction area.

It should be noted that in this embodiment, after the touch interference area is determined, the display area of the touch screen can be controlled to shrink adaptively, as long as the display area and the touch interference area do not overlap.

It should also be noted that in this embodiment, the touch interference range is preferably determined only by obtaining the magnetic field strength signal of the NFC coil, and the touch interference range can also be obtained in other ways; Interference range, and every time NFC interaction is performed, the display area of the touch screen is controlled to be outside the maximum interference range.

Further, in one embodiment of the present invention, obtaining the magnetic field strength signal of the magnetic field generated by the NFC coil of the mobile terminal when the mobile terminal interacts with the external communication device through NFC includes: obtaining the NFC activation signal of the mobile terminal; Whether it is in the NFC interaction state with the external communication device; if so, obtain the magnetic field strength signal of the magnetic field generated by the NFC coil of the mobile terminal.

Obtaining and processing the magnetic field strength signal of the NFC coil of the mobile terminal in real time will keep the corresponding hardware for implementing the method in a standby state, resulting in unnecessary power consumption. In this embodiment, the magnetic field strength signal is acquired only when the NFC activation signal of the mobile terminal is acquired and it is determined to perform NFC interaction with an external communication device. That is, when the mobile terminal turns on the NFC function, the process of the touch screen display control method provided in the above embodiments is triggered, which can greatly reduce power consumption.

In one embodiment of the present invention, reducing the display area of the touch screen, and the reduced current display area does not overlap with the touch interference area includes: obtaining the information of the touch screen and the touch interference area that do not overlap according to the touch interference area Touch the normal area; control the display area of the touch screen to shrink to the preset position of the touched normal area.

In this embodiment, the display area of the touch screen can be controlled to shrink to the 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 on the upper part of the mobile terminal, the reduced current display area is close to the lower right side of the entire touch screen.

It should be noted that, in this embodiment, after the display area is reduced, the position of the display area on the touch screen can be changed accordingly according to the user's operation on the touch screen, such as adaptively shrinking the display area to the lower right side of the touch screen, When the user clicks on a blank area of the display area (that is, an area without any application in the display area), as the user's finger moves, the display area moves accordingly until the user's finger leaves the touch screen.

Further, after reducing the display area of the touch screen, and there is no overlapping area between the reduced current display area and the touch interference area, it also includes: judging whether the mobile terminal and the external communication device disconnect the NFC interaction; if so, then control the touch screen to restore the full screen show.

In this embodiment, when the mobile terminal disconnects from the NFC interaction with the external communication device, the full-screen display is resumed, so that the mobile terminal returns to the normal use state, so that the user can operate and use it.

When the external communication device and the mobile terminal perform NFC interaction, since the relative position of the external communication device and the mobile terminal is random, the magnetic field generated by the NFC coil of the mobile terminal is different for each interaction, so the touch interference area is usually The case is different.
