[0059] It should be noted that the field-weighted adjustment method for touchscreens in touch mode provided in this application can be applied to terminals, such as smartphones, computers, tablets, smart TVs, smartwatches, portable computer terminals, and desktop computers. For ease of explanation, this application uses a terminal as the implementing entity for illustration, wherein the terminal has a built-in touchscreen function module and an NFC module.

[0060] The technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0061] Referring to Figure 1, this application first provides an embodiment of a field-weighted adjustment method for a touchscreen in a touch state, which includes:

[0062] S101. After the touch screen function module detects that the touch screen has received a touch operation, it sends a first indication information to the NFC module. The first indication information is used to indicate that the touch screen is in a touch state.

[0063] In addition to the logic processing module, the terminal described in this application also includes an NFC module and a touchscreen function module. When the touchscreen function module detects that the touchscreen has been touched, it sends first indication information to the NFC module based on the touch operation. The first indication information is generated by the touchscreen function module based on the touch operation received by the touchscreen.

[0064] The NFC module determines that the touchscreen is in a touch state based on the first indication information. When the NFC module undergoes a field strength transition, the touchscreen module may encounter anomalies in reading the user's touch operation. This typically manifests as the touchscreen reading a swipe action instead of a tap, or incorrect tap coordinate readings. To avoid this, after a touch operation occurs, the touchscreen module generates the first indication information based on the touch operation and sends it to the NFC module. This allows the NFC module to understand the current interaction state between the touchscreen module and the user, enabling it to provide subsequent feedback based on the touch operation.

[0065] S102 After receiving the first indication information, the NFC module keeps the current field strength switch state unchanged.

[0066] The NFC module receiving the first indication information indicates that the NFC module obtains that the current touch screen is in a touch state. In order to avoid the field strength change affecting the reading of the touch screen on the touch action, the NFC module maintains the current field strength switch state when the touch screen is in the touch operation state, that is, if the current NFC module field strength switch state is on, the NFC module field strength is kept on; if the current NFC module field strength switch state is off, the NFC module field strength is kept off, so that the current NFC module field strength switch state is maintained in a stable state.

[0067] In the embodiment, the first indication information is generated by performing a touch operation on the touch screen, so that the NFC module can determine the current touch state of the touch screen according to the first indication information when receiving the first indication information, and maintain the current field strength according to the touch state, so that the touch screen generates feedback of the touch operation without being affected by the change of the field strength.

[0068] Please refer to FIG. 2, another embodiment of the field strength adjustment method of the touch screen in the touch state is provided, which includes:

[0069] S201, before performing the field strength change operation, the NFC module determines whether the touch screen is in a touch state;

[0070] In actual situations, the NFC module is in a polling state when used. In the polling state, the NFC module generates a radio frequency field to actively search for NFC tags or other devices in the surrounding environment. At this time, the radio frequency field of the NFC module produces a field strength. In the polling process, the NFC device needs to dynamically adjust the strength of the radio frequency field to adapt to different distances and different RF protocols of target devices.

[0071] Before the NFC module performs the field strength switch change operation, the terminal obtains the touch state of the touch screen through the register feedback of the touch screen, and determines the subsequent execution logic according to the touch state of the touch screen. When the touch screen is in the touch state, step S202 is performed; when the touch screen is not in the touch state, step S203 is performed.

[0072] S202, if it is determined that the touch screen is in the touch state, the current field strength switch state is maintained unchanged;

[0073] When the touch screen is in the touch state, it indicates that the current change of the field strength switch state will cause the touch screen to work abnormally. Therefore, the NFC module maintains the field strength switch state unchanged according to the touch state until the touch state of the touch screen ends. When the touch state of the touch screen ends, the terminal controls the NFC module to resume the normal field strength operation.

[0074] S203, if it is determined that the touch screen is not in the touch state, a normal field strength operation is performed.

[0075] The touch screen not being in the touch state means that the touch screen does not need to generate feedback to the touch action at present, and there is no risk of abnormal feedback, in which case the NFC module performs normal field strength operation, that is, the NFC module opens the field strength to search for the surrounding NFC device according to the polling interval of the polling mode.

[0076] In this embodiment, the NFC module acquires the touch state of the touch screen function module before performing the field strength change operation, so as to avoid the touch screen function module being touched when the NFC module performs the field strength change operation, thereby avoiding the abnormal feedback of the touch point of the touch screen module.

[0077] Referring to FIG. 3, another embodiment of the field strength adjustment method of the touch screen in the touch state is provided, which includes the following steps.

[0078] S301, after the touch screen function module detects that the touch screen receives a touch operation, the touch screen function module sends first indication information to the NFC module, the first indication information being used to indicate that the touch screen is in the touch state;

[0079] The step S301 in this embodiment is similar to the step S101 in the foregoing embodiments, and will not be described here.

[0080] S302, after the NFC module receives the first indication information, the NFC module performs field strength detection;

[0081] The working principle of the touch screen is to accurately locate the position of the finger touching the screen by measuring the small change of the capacitance, which makes the touch screen sensitive to the change of the external electromagnetic environment. Specifically, when the finger touches the screen, the capacitance on the touch screen changes, which is detected by the touch screen controller and the touch position is determined. If the NFC module is used near the touch screen, the magnetic field change generated by the NFC module may be incorrectly interpreted by the touch screen as a touch event, resulting in false touch or reduced accuracy. In addition, the load modulation technology in NFC communication, that is, modulating the magnetic field by changing the load resistance of the antenna, may also affect the normal work of the touch screen. Because this modulation may cause the electromagnetic environment on the touch screen to change, and then cause the error of the capacitance measurement.

[0082] But the premise of causing the error is that the field strength generated by the NFC module is greater than the field strength affecting the touch screen, so before limiting the working state of the NFC module, the field strength currently generated by the NFC module needs to be acquired.

[0083] The first indication information indicates that the touch screen is currently in a touch state, and the NFC module executes a field strength change that affects the reading of touch instructions by the touch screen. However, in actual situations, the field strength needs to reach a threshold value to affect the touch screen. Therefore, after the NFC module receives the first indication information, the NFC module detects the field strength, and determines whether the field strength generated by the NFC module currently affects the normal operation of the touch screen by comparing the current field strength of the NFC module with the preset threshold value. If the current field strength is not greater than the preset threshold value, step S303 is executed. If the current field strength is greater than the preset threshold value, step S304 is executed.

[0084] S303, if the NFC module detects that the current field strength is not greater than the preset threshold value, a normal field strength operation is executed.

[0085] The preset threshold value is a preset value calculated according to the actual position relationship between the device in which the touch screen is located and the NFC module, and the parameters of the touch screen and the NFC module. The field strength within the range of the preset threshold value does not affect the touch feedback of the touch screen. Therefore, when the NFC module determines that the current field strength is less than the preset threshold value, the NFC module executes a normal field strength operation.

[0086] S304, if the NFC module detects that the current field strength is greater than the preset threshold value, the current field strength switch state is maintained.

[0087] When the NFC module detects that the current field strength is greater than the preset threshold value, it indicates that the field strength generated by the current NFC module affects the feedback of the touch screen to the touch operation. Therefore, the NFC module maintains the current field strength switch state to avoid abnormal touch feedback of the touch screen caused by the field strength jump. Then, step S305 is executed.

[0088] S305, after the touch screen function module detects that the touch screen does not receive a touch operation, the second indication information is sent to the NFC module. The second indication information is used to indicate that the touch screen is in a non-touch state.

[0089] Specifically, the second indication information indicates that the terminal does not detect a touch operation generated by the current touch screen. Similar to the first indication information, after the touch screen function module determines the second indication information according to the feedback of the touch screen, the touch screen function module sends the second indication information to the NFC module, so that the NFC module runs the working logic according to the second indication information.

[0090] S306, after the NFC module receives the second indication information, the normal field strength operation is restored.

[0091] The time when the second indication information is generated can be after the first indication information is generated, or before the first indication information is generated, and the specific time is not limited herein. When the terminal determines to generate the second indication information, it indicates that the current touch screen is not in the touched state, and the field strength change of the NFC module does not affect the feedback of the touch screen. Therefore, the NFC module performs the normal field strength operation. If the second indication information is generated after the first indication information, it indicates that the NFC module enters the field strength maintaining state when the touch screen is in the previous state. After the second indication information is determined, the NFC module ends the field strength maintaining state and restores the normal field strength operation of the NFC module.

[0092] In the embodiment, the NFC module judges the current field strength after receiving the first indication information, and determines whether the current field strength needs to be maintained according to the judgment result, so that when the current field strength does not reach the preset threshold value affecting the touch screen function module, the NFC module normally performs the operation of changing the field strength switch state, thereby reducing the limitation of the interaction state of the touch screen function module on the working state of the NFC module. The touch screen function module generates the second indication information after the user's touch interaction with the user stops, so that the NFC module can restore the normal working state according to the second indication information after maintaining the field strength switch state through the first indication information.

[0093] Please refer to FIG. 4, another embodiment of the field strength adjustment method of the touch screen in the touched state is provided, which includes the following steps:

[0094] S401, after the touch screen function module detects that the touch screen receives the touch operation, if the touch screen function module determines that the current NFC module is in the field strength switch jump state, the first indication information is sent to the NFC module, and the first indication information is used to indicate that the touch screen is in the touched state;

[0095] Specifically, the first indication information is used to indicate that the NFC module maintains the current field strength switch state. The first indication information is generated by the touch screen function module according to the feedback that the touch screen is in the touched state, and therefore represents that the touch screen is interacting with the user at this time. In order to avoid the abnormal touch feedback of the touch screen caused by the field strength switch jump when the touch screen interacts with the user, the terminal sends the first indication information to the NFC module when the NFC module performs the field strength switch jump, so that the NFC module determines the current working state of the touch screen according to the first indication information. When the NFC module is not in the field strength switch jump state, step S402 is performed. After the NFC module sends the first indication information, step S404 is performed.

[0096] S402, if the touch screen function module determines that the current NFC module is not in the field strength switch jump state, the field strength switch change of the NFC module is detected in the touched state.

[0097] When the touch screen function module determines that the NFC module is not currently in the field strength switch jump state, it represents that the current touch screen will not be affected by the field strength change of the NFC module, but in the actual situation, the user's interaction with the touch screen is continuous, so when the terminal determines that the touch screen is interacting with the user, it will continue to detect the field strength jump state of the NFC module. During the continuous detection, if it is detected that the NFC module is in the field strength switch jump state, step S403 is executed.

[0098] S403, after detecting that the NFC module is in the field strength switch jump state, first indication information is sent to the NFC module;

[0099] After step S402, while detecting the field strength switch change of the NFC module, if the touch screen function module detects that the field strength switch of the NFC module changes to the jump state, first indication information is sent to the NFC module, so that the NFC module does not occur field strength jump before the user interaction touch action of the touch screen is completed.

[0100] Specifically, the field strength switch jump state is a working state of the NFC module fed back to the touch screen function module. When this state is generated, it means that the NFC module enters the state of searching for surrounding NFC devices according to the time setting of the polling mode to generate the demand for field strength jump. When the touch screen is in the interaction state at this time, the field strength jump generated by the NFC module will affect the touch feedback when the touch screen interacts with the user. In order to avoid this situation, after the touch screen function module determines that the NFC module enters the field strength switch jump state, first indication information is sent to the NFC module, so that the subsequent NFC module keeps the current field strength according to the first indication information until the user interaction with the touch screen ends.

[0101] S404, after the NFC module receives the first indication information, the current field strength switch state is kept unchanged;

[0102] Step S404 in the embodiment is similar to step S102 in the foregoing embodiment, and will not be described here in detail.

[0103] S405, after the touch screen function module does not detect that the touch screen receives a touch operation, second indication information is sent to the NFC module, and the second indication information is used to indicate that the touch screen is in a non-touch state;

[0104] S406, after the NFC module receives the second indication information, the normal field strength operation is restored.

[0105] Steps S405 to S406 in the embodiment are similar to steps S305 to S306 in the foregoing embodiment, and will not be described here in detail.

[0106] In the embodiment, the field strength jump state of the NFC module has an impact on the touch feedback when the touch screen interacts with the user. To avoid this, the terminal uses the touch state of the touch screen and the field strength switch jump state of the NFC module as an interrupt identifier. When the interrupt identifier is generated, the terminal preferentially processes the task corresponding to the interrupt identifier, that is, when the touch screen generates a touch state, the terminal acquires the field strength switch state of the NFC module, and when the field strength switch state of the NFC module changes, the terminal also acquires the current touch state of the touch screen, so as to reduce the impact of the field strength jump of the NFC module on the touch feedback of the touch screen.
