Before the present disclosure is described in detail, terms, application scenarios, and execution subjects related to the embodiments of the present disclosure will be briefly described.

Next, a brief description is given of an application scenario related to an embodiment of the present disclosure.
In an actual application scenario, if the radio frequency antenna and the touch screen hardware circuit are closely arranged, when the radio frequency antenna works, the transmission power of the transmitted radio frequency signal is absorbed by the hardware circuit of the touch screen and converted into energy surge or parasitic capacitance, and the interference source greatly affects the working stability of the touch screen, which easily causes the abnormal working of the touch screen.

All the above optional technical solutions can be combined arbitrarily to form optional embodiments of the present disclosure, and the embodiments of the present disclosure are not described in detail again.
According to different specific contents included in the radio frequency state information, the specific implementation process of the touch screen control method is also different, and then, the following two embodiments of fig. 2 and fig. 3 will be described in detail.
Referring to fig. 2, fig. 2 is a flowchart illustrating a touch screen control method according to another exemplary embodiment, where the embodiment of the present disclosure is described by taking the example that the radio frequency state information includes a transmission frequency and a transmission power, the touch screen control method is used in a terminal, and the method may include the following implementation steps:
in step 201, radio frequency state information of a radio frequency signal to be output is determined, and the radio frequency state information is used for describing an output state of the radio frequency signal.
As mentioned above, the rf signal refers to a signal emitted by an rf antenna driven by an rf driving module in the terminal. In the embodiment of the disclosure, before the rf signal is not transmitted, the rf driving module in the terminal may output the rf state information of the rf signal to be transmitted. Further, the rf driving module may transmit the rf status information of the rf signal to a state machine module in the terminal.
It should be noted that, here, the radio frequency status information includes a transmission frequency and a transmission power, for example, the transmission frequency may be GSM900 or GSM1800, etc.
In step 202, when the radio frequency status information includes a transmission frequency and a transmission power, a target touch key in the touch screen is determined, where the target touch key is a key affected by a radio frequency signal whose operating frequency is the transmission frequency and whose maximum transmission power is the transmission power.
In an actual application scenario, different transmission frequencies may interfere with touch keys at different positions, and the maximum transmission power of the radio frequency signal at different transmission frequencies is different, so that the degree of influence on the touch keys is also different, for example, the maximum transmission power of the transmission frequency GSM900 only interferes with the return touch key, the maximum transmission power of GSM1800 only interferes with the menu item touch key, and so on.
Therefore, in the embodiment of the present disclosure, when the radio frequency state information includes the transmission frequency and the transmission power, the terminal needs to determine the target touch key affected by the radio frequency signal whose operating frequency is the transmission frequency and whose maximum transmission power is the transmission power.
Further, the target touch key may be determined by a state machine module in the terminal based on the radio frequency state information. For example, when the radio frequency status information includes a transmission frequency and a transmission power, the terminal may store therein a plurality of correspondences between the radio frequency status information and touch key identifiers, where each touch key identifier may be used to uniquely identify one touch key. Therefore, the state machine module can acquire the touch key identification corresponding to the radio frequency state information of the radio frequency signal to be output, and determine the touch key corresponding to the touch key identification as the target touch key.
The state machine module may then inform the touch screen module of the target touch key. In a possible implementation manner, the state machine module may notify the touch screen module in a notification message, where the notification message may include the touch key identifier of the target touch key.
In step 203, the touch condition of the target touch key is changed.
In a specific implementation, the touch screen module may change the touch condition of the target touch key after receiving the notification message sent by the state machine module. The changing of the touch condition of the target touch key may include the following possible implementation manners:
the first mode is as follows: and increasing a preset threshold value by the reported threshold value of the touch screen, wherein the reported threshold value is used for limiting at least one of touch duration, touch signal strength and touch area size.
The preset threshold may be set by a user according to actual needs in a self-defined manner, or may be set by the default of the terminal, which is not limited in the embodiment of the present disclosure.
It should be noted that, in the embodiment of the present invention, the reporting threshold of the target touch key in the touch screen is actually increased by a preset threshold.
In practical implementation, if the interference generated by the radio frequency signal is higher than the reporting threshold, the touch screen module is likely to report incorrectly, that is, in fact, the user does not touch the target touch key in the touch screen, and the touch signal is triggered by the radio frequency signal, so that the touch screen is likely to report incorrectly, thereby causing an abnormal operation. Therefore, when the touch screen module receives the notification message sent by the state machine module, the reporting threshold value of the target touch key can be increased.
The second mode is as follows: and starting a multi-frame filtering algorithm, wherein the multi-frame filtering algorithm is used for increasing the times that the touch states all accord with the reporting threshold value of the touch screen in the touch condition.
It should be noted here that the terminal does not start the multi-frame filtering algorithm without interference, i.e. the multi-frame filtering algorithm is normally in an off state.
In an actual application scenario, because the interference duration generated by the radio frequency signal is limited, in order to avoid the interference generated by the radio frequency signal, the touch screen module in the terminal may also start a multi-frame filtering algorithm. Therefore, the touch screen module can detect whether the touch state is consistent with the reporting threshold value of the target touch key for multiple times, or whether the times that the touch state is consistent with the reporting threshold value of the target touch key reach the preset times.
The preset times can be set by a user according to actual needs in a self-defined manner, or can be set by a terminal in a default manner, which is not limited by the embodiment of the disclosure.
Further, if the touch state is detected to be consistent with the reported threshold value of the target touch key, the touch screen module determines that the touch signal is triggered by the user, otherwise, the touch screen module considers that the touch signal is triggered by the radio frequency signal. Therefore, the effect of avoiding the interference of the radio frequency signals can be achieved after the multi-frame filtering algorithm is started.
It should be noted that, here, the description is only given by taking as an example the case of changing the touch condition of the target touch key, including the above several possible implementations. In practical implementation, changing the touch condition of the target touch key may also include other forms, for example, the touch message reporting function may also be turned off, that is, the touch function is turned off, or the software and the hardware may also be calibrated in a reset manner, which is not limited in this embodiment of the disclosure.
In step 204, the touch screen is controlled based on the changed touch condition.
In practical application, after the touch condition of the touch screen is changed, the interference of the radio frequency signal can be avoided, for example, if the reporting threshold value of the target touch key in the touch screen is increased, the interference generated by the radio frequency signal can be below the reporting threshold value, that is, when the target touch key in the touch screen is controlled based on the changed touch condition, the wrong reporting caused by the interference of the radio frequency signal can be avoided, so as to avoid the misoperation of the touch screen, and thus ensure the normal work of the touch screen.
In the embodiment of the disclosure, the radio frequency state information of the radio frequency signal to be output is determined, so as to change the touch condition of the touch screen according to the radio frequency state information, that is, the condition that the touch operation is detected by the touch screen is changed, and the touch screen is controlled based on the changed touch condition, so that the influence of the radio frequency signal on the touch screen can be avoided, and the abnormal operation of the touch screen is avoided.
Referring to fig. 3, fig. 3 is a flowchart illustrating a touch screen control method according to another exemplary embodiment, where the embodiment of the present disclosure takes the radio frequency state information including a transmission time interval and a transmission duration as an example, the touch screen control method is applied in a terminal, and the method may include the following implementation steps:
in step 301, radio frequency state information of a radio frequency signal to be output is determined, where the radio frequency state information is used to describe an output state of the radio frequency signal.
As mentioned above, the rf signal refers to a signal emitted by an rf antenna driven by an rf driving module in the terminal. In the embodiment of the disclosure, before the rf signal is not transmitted, the rf driving module in the terminal may output the rf state information of the rf signal to be transmitted. Further, the rf driving module may transmit the rf status information of the rf signal to a state machine module in the terminal.
It should be noted that, here, the radio frequency state information includes a transmission time interval and a transmission duration, for example, the transmission time interval is 500ms, and the transmission duration is 20 ms.
In step 302, when the radio frequency status information includes a transmission time interval and a transmission duration, the touch condition of the touch screen is changed and the transmission duration is maintained every the transmission time interval.
When the radio frequency state information comprises a transmission time interval and a transmission duration, the radio frequency antenna transmits a radio frequency signal every other transmission time duration and continues the transmission duration. In order to avoid interference caused by radio frequency signals transmitted by the radio frequency antenna every time, the touch condition of the touch screen is changed and the transmission duration is maintained at intervals of the transmission time.
For example, if the radio frequency status information includes a transmission time interval and a transmission duration of 500ms and 20ms, respectively, the terminal changes the touch condition of the touch screen every 500ms and maintains the touch condition for 20ms, so as to avoid interference generated by the radio frequency signal within the 20 ms.
In a possible implementation manner, the touch condition may be determined by a state machine module, and further, the state machine module receives radio frequency state information output by the radio frequency driving module, and acquires a corresponding touch condition based on the radio frequency state information. For example, the terminal may store a corresponding relationship between a plurality of radio frequency status information and a plurality of touch conditions, and thus, the state machine module may obtain the touch conditions corresponding to the radio frequency status information from the corresponding relationship. And then, the state machine module transmits the touch condition to the touch screen module in a notification message mode, and the touch screen module changes the touch condition of the touch screen.
The changing of the touch condition of the touch screen may include the following possible implementation manners:
the first mode is as follows: and increasing a preset threshold value by the reported threshold value of the touch screen, wherein the reported threshold value is used for limiting at least one of touch duration, touch signal strength and touch area size.
The preset threshold may be set by a user according to actual needs in a self-defined manner, or may be set by the default of the terminal, which is not limited in the embodiment of the present disclosure.
It should be noted that, in the embodiment of the present invention, the reporting threshold values of other touch areas in the touch screen except the touch key may be actually increased by a preset threshold value. Or, the reporting threshold values of the touch keys in the touch screen may be all increased by preset threshold values. Or, the reporting threshold values of the touch key in the touch screen and the reporting threshold values of other touch areas except the touch key may be increased by a preset threshold value, which is not limited in the embodiment of the present disclosure.
In practical implementation, if the interference generated by the radio frequency signal is higher than the reporting threshold, the touch screen module is likely to report incorrectly, that is, the user does not actually touch the touch screen, and the touch signal is triggered by the radio frequency signal, so that the touch screen is likely to report incorrectly, thereby causing an abnormal operation. Therefore, the terminal can improve the reporting threshold value through the touch screen module.
For example, in a possible application scenario, when the terminal starts a glove operation mode (i.e., a user can operate a mobile phone with a glove), the reporting threshold value is lower than that in the normal mode, and the reporting of the touch screen module is abnormal due to interference noise of the radio frequency signal. In this case, if the state machine module informs the touch screen module that there will be interference of the radiation antenna, the expected radiation duration is 20ms, and the transmission time interval is 500ms, the touch screen module may temporarily increase the reporting threshold at the same transmission time interval, for example, increase the reporting threshold and maintain the reporting threshold for 20ms, so that the interference of the radio frequency signal can be avoided.
The second mode is as follows: and starting a multi-frame filtering algorithm, wherein the multi-frame filtering algorithm is used for increasing the times that the touch states all accord with the reporting threshold value of the touch screen in the touch condition.
It should be noted here that the terminal does not start the multi-frame filtering algorithm without interference, i.e. the multi-frame filtering algorithm is normally in an off state.
In an actual application scenario, because the interference duration generated by the radio frequency signal is limited, in order to avoid the interference generated by the radio frequency signal, the touch screen module in the terminal may also start a multi-frame filtering algorithm. Therefore, the touch screen module can detect whether the touch state is consistent with the reporting threshold value of the touch screen or not for multiple times, or whether the times that the touch state is consistent with the reporting threshold value of the touch screen reaches the preset times or not.
The preset times can be set by a user according to actual needs in a self-defined manner, or can be set by a terminal in a default manner, which is not limited by the embodiment of the disclosure.
Further, if the touch state is detected to be consistent with the reported threshold value of the touch screen, the touch screen module determines that the touch signal is triggered by the user, otherwise, the touch signal is considered to be triggered by the radio frequency signal. Therefore, the effect of avoiding the interference of the radio frequency signals can be achieved after the multi-frame filtering algorithm is started.
It should be noted that, here, the description is only given by taking as an example the case of changing the touch condition of the target touch key, including the above several possible implementations. In practical implementation, changing the touch condition of the target touch key may also include other forms, for example, the touch message reporting function may also be turned off, that is, the touch function is turned off, or the software and the hardware may also be calibrated in a reset manner, which is not limited in this embodiment of the disclosure.
In step 303, the touch screen is controlled based on the changed touch condition.
In practical application, after the touch condition of the touch screen is changed, the interference of the radio frequency signal can be avoided, for example, if the reporting threshold of the touch screen is increased, the interference generated by the radio frequency signal can be below the reporting threshold, that is, when the touch screen is controlled based on the changed touch condition, the wrong reporting caused by the interference of the radio frequency signal can be avoided, so as to avoid the misoperation of the touch screen, and ensure the normal work of the touch screen.
In the embodiment of the disclosure, the radio frequency state information of the radio frequency signal to be output is determined, so as to change the touch condition of the touch screen according to the radio frequency state information, that is, the condition that the touch operation is detected by the touch screen is changed, and the touch screen is controlled based on the changed touch condition, so that the influence of the radio frequency signal on the touch screen can be avoided, and the abnormal operation of the touch screen is avoided.
It should be noted that the embodiments shown in fig. 2 and fig. 3 are only exemplary, and in an actual implementation, when the radio frequency state information includes other contents, the radio frequency state information may also be implemented in the above manner, or implemented by using a combination of the above mentioned implementations. For example, when the radio frequency status information includes a transmission frequency, a transmission power, a transmission time interval, and a transmission duration at the same time, in an implementation process, the target touch key may be determined according to the transmission frequency and the transmission power, and then, the touch condition of the target touch key is changed every other transmission time interval and the transmission duration is maintained.
