Description

Technical Field

[0001] The present application relates to the field of NFC technology, and in particular to a method, system and device for adjusting the field intensity of a touch screen in a touch state. Background Art

[0002] Near Field Communication (NFC) technology is a technology that allows electronic devices to communicate wirelessly within a very short distance.

[0003] In actual situations, NFC is used with display devices, which are usually touch screens for easy interaction. However, the NFC function module frequently switches the field strength on and off during card inquiry or interaction. In the case of frequent switching of the field strength, when a user clicks or draws on the touch panel (TP), the TP will be disturbed by the switching field strength, resulting in disconnection and jump points during interaction, or deflection and inability to draw smoothly when drawing.

[0059] It should be noted that the field intensity adjustment method of the touch screen in the touch state provided in the present application can be applied to a terminal, for example, the terminal can be a smart phone or a computer, a tablet computer, a smart TV, a smart watch, a portable computer terminal, or a desktop computer, etc. For the convenience of explanation, the present application takes the terminal as the execution subject for example, wherein the terminal has a built-in touch screen function module and an NFC module.

[0060] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0061] See also Figure 1 The present application first provides an embodiment of a method for adjusting field intensity of a touch screen in a touch state, the embodiment comprising:

[0062] S101, 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, where 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 needs to include an NFC module and a touch screen function module. When the touch screen is detected to be touched, the touch screen function module sends a first indication message to the NFC module according to the touch operation, and the first indication message is generated by the touch screen function module according to the touch operation received by the touch screen.

[0064] The NFC module determines that the touch screen is in a touch state through the first indication information. When the NFC module performs a field strength jump, the touch screen function module will produce an abnormality in reading the user's touch operation on the touch screen, which is generally manifested in that when the touch screen is pressed, the action read by the touch screen becomes a sliding action, and the click coordinates are read incorrectly. To avoid this situation, after the touch screen generates a touch operation, the touch screen function module generates the first indication information according to the touch operation, and sends the first indication information to the NFC module, so that the NFC module can obtain the interactive state of the touch operation currently being performed by the touch screen function module and the user, so that the NFC module can make subsequent feedback according to the touch operation.

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

[0066] When the NFC module receives the first indication information, it means that the NFC module has obtained that the current touch screen is in a touch state. In order to prevent the field strength change from affecting the touch screen's reading of the touch action, the NFC module will maintain the current field strength switch state when the touch screen is in a touch operation state, that is: if the current NFC module field strength switch state is on, the NFC module field strength is maintained in the on state; if the current NFC module field strength switch state is off, the NFC module field strength is maintained in the off state, so that the current NFC module field strength switch state is maintained in a stable state.

[0067] In this embodiment, the first indication information is generated by performing a touch operation on the touch screen, so that when the NFC module receives the first indication information, it can determine the current touched state of the touch screen according to the first indication information, and maintain the current field strength according to the touch state, so that when the touch screen generates feedback of the touch operation, it will not be affected by the change in field strength.

[0068] See also Figure 2 The present application provides another embodiment of a method for adjusting field intensity of a touch screen in a touch state, the embodiment comprising:

[0069] S201, before performing a 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 in use. In the polling state, the NFC module will generate 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 will generate a field strength. During the polling process, the NFC device needs to dynamically adjust the strength of the radio frequency field to adapt to target devices at different distances and with different RF protocols.

[0071] Before the NFC module performs the field strength switch change operation, the terminal obtains the current 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 executed, and when the touch screen is not in the touch state, step S203 is executed.

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

[0073] When the touch screen is in a touch state, it means that the current change of the field strength switch state will cause the touch screen to work abnormally. Therefore, the NFC module will maintain 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 will control the NFC module to resume normal field strength operation.

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

[0075] If the touch screen is not in a touch state, it means that the current touch screen does not need to generate feedback for touch actions, so there is no risk of abnormal feedback. In this case, the NFC module will perform normal field strength operation. Normal field strength operation is that the NFC module turns on the field strength to search for surrounding NFC devices 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 to avoid the touch screen function module being touched when the NFC module performs the field strength switch state change operation, resulting in abnormal contact feedback of the touch screen module.

[0077] See also Figure 3 The present application provides another embodiment of a method for adjusting field intensity of a touch screen in a touch state, the embodiment comprising:

[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, where the first indication information is used to indicate that the touch screen is in a touch state;

[0079] Step S301 in this embodiment is similar to step S101 in the aforementioned embodiment, and will not be described in detail here.

[0080] S302: After receiving 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 where the finger touches the screen by measuring the slight change in capacitance, which makes the touch screen sensitive to changes in the external electromagnetic environment. Specifically, when a finger touches the screen, it changes the capacitance on the touch screen, which is detected by the touch screen controller and determines the touch position. If an NFC module is used near the touch screen, the magnetic field changes it generates may be mistakenly interpreted by the touch screen as a touch event, resulting in false touches 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 operation of the touch screen. This is because this modulation may cause changes in the electromagnetic environment on the touch screen, which in turn causes errors in capacitance measurement.

[0082] However, the premise for causing the error is that the field strength generated by the NFC module is greater than the field strength affected by the touch screen. Therefore, before limiting the working state of the NFC module, it is necessary to first obtain the field strength currently generated by the NFC module.

[0083] The first indication information indicates that the touch screen is currently in a touch state. When the NFC module executes a field strength change, the touch screen's reading of touch instructions will be affected. However, in actual situations, the field strength that can affect the touch screen needs to reach a threshold. Therefore, after the NFC module receives the first indication information, the NFC module will perform an intensity detection on the field strength, and by comparing the current field strength of the NFC module with the preset threshold, it is determined whether the field strength generated by the current NFC module will affect the normal operation of the touch screen. If the current field strength is not greater than the preset threshold, step S303 is executed; if the current field strength is greater than the preset threshold, step S304 is executed.

[0084] S303: If the NFC module detects that the current field strength is not greater than the preset threshold, a normal field strength operation is performed;

[0085] The preset threshold is a preset value calculated based on the actual position relationship between the device where the touch screen is located and the NFC module, as well as the parameters of the touch screen and the NFC module. The field strength within the preset threshold will 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, the NFC module will perform normal field strength operations.

[0086] S304: If the NFC module detects that the current field strength is greater than the preset threshold, the current field strength switch state is maintained unchanged;

[0087] When the NFC module detects that the current field strength is greater than the preset threshold, it means that the field strength generated by the current NFC module will affect the touch screen's feedback on the touch operation. Therefore, the NFC module will maintain the on / off state of the current field strength to avoid abnormal touch feedback on the touch screen caused by field strength jumps, and then execute step S305.

[0088] S305: after the touch screen function module fails to detect that the touch screen has received a touch operation, send second indication information to the NFC module, where 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 has not detected a touch operation on the current touch screen. Similar to the first indication information, after the touch screen function module determines the second indication information based on the touch screen feedback, the touch screen function module will send 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 receiving the second indication information, the NFC module resumes normal field strength operation.

[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. The specific time is not limited here. When the terminal determines to generate the second indication information, it means that the current touch screen is not in a touched state, and the change of field strength of the NFC module will not affect the feedback of the touch screen. Therefore, the NFC module will perform normal field strength operation. If the second indication information is generated after the first indication information, it means that when the touch screen was in the previous state, the NFC module entered the field strength maintenance state. After determining the second indication information, the NFC module will end the field strength maintenance state and restore the normal field strength operation of the NFC module.

[0092] In this embodiment, the NFC module judges its current field strength after receiving the first indication information, and determines whether it needs to maintain the switch state of the current field strength according to the judgment result, so that when the current field strength does not reach the preset threshold that affects the touch screen function module, the NFC module normally performs the field strength switch state change operation, thereby reducing the restriction of the NFC module's own working state on the interactive state of the touch screen function 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 resume the normal working state according to the second indication information after maintaining the field strength switch state through the first indication information.

[0093] See also Figure 4 The present application provides another embodiment of a method for adjusting field intensity of a touch screen in a touch state, the embodiment comprising:

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

[0095] Specifically, the first indication information is used to instruct the NFC module to maintain the current field strength switch state. The first indication information is generated by the touch screen function module based on the feedback that the touch screen is in a touch state. Therefore, it represents that the touch screen is interacting with the user at this time. In order to avoid abnormal touch feedback caused by the touch screen interacting with the user due to the field strength switch jump, the terminal will send the first indication information to the NFC module when the NFC module is performing 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 executed. After the NFC module sends the first indication information, step S404 is executed.

[0096] S402: If the touch screen function module determines that the current NFC module is not in a field strength switch jump state, then keep detecting the field strength switch change of the NFC module in the touch state;

[0097] When the touch screen function module determines that the NFC module is not currently in the field strength switch jump state, it means that the current touch screen will not be affected by the field strength change of the NFC module. However, in actual situations, the interaction between the user and the touch screen is continuous. Therefore, 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 process, 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 a field strength switch jump state, sending first indication information to the NFC module;

[0099] After step S402, while continuing to detect the change of the field strength switch of the NFC module, if the touch screen function module detects that the field strength switch of the NFC module changes to a jumping state, it will send the first indication information to the NFC module, so that the field strength of the NFC module will not 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 that is fed back to the touch screen function module by the NFC module. When this state is generated, it indicates that the NFC module enters the state of searching for surrounding NFC devices according to the time setting of the polling mode and generates a need for field strength jump. When the touch screen is in an interactive 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. To avoid this situation, after the touch screen function module determines that the NFC module enters the field strength switch jump state, it will send a first indication information to the NFC module, so that the subsequent NFC module maintains the current field strength according to the first indication information until the user ends the interaction with the touch screen.

[0101] S404: After receiving the first indication information, the NFC module maintains the current field strength switch state unchanged;

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

[0103] S405, after the touch screen function module fails to detect that the touch screen has received a touch operation, sending second indication information to the NFC module, where the second indication information is used to indicate that the touch screen is in a non-touch state;

[0104] S406: After receiving the second indication information, the NFC module resumes normal field strength operation.

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

[0106] In this embodiment, the field strength jump state of the NFC module will affect the touch feedback when the touch screen interacts with the user. To avoid this situation, the terminal will use the touch state of the touch screen and the field strength switch jump state of the NFC module as interrupt identifiers. When the interrupt identifier is generated, the terminal will give priority to processing the task corresponding to the interrupt identifier, that is, when the touch screen generates a touch state, the terminal will obtain the field strength switch state of the NFC module, and when the field strength switch state of the NFC module changes, the terminal will also obtain the current touch state of the touch screen to reduce the impact of the NFC module field strength jump on the touch feedback of the touch screen.
