Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart of a touch screen response triggering method provided in an embodiment of the present invention, and as shown in fig. 1, the embodiment provides a touch screen response triggering method applied to a terminal, including the following steps:
Specifically, the transmitting end in this step may be specifically a transmitting end of the touch screen control module, and the transmitting end transmits a touch scan sending signal, where a high level portion of the touch scan sending signal includes N detection signals, for example, the touch scan sending signal is a periodic pulse scan signal, and a high level portion of the periodic pulse scan signal includes N detection signals, and the N detection signals are not overlapped with a high level of a radio frequency signal transmitted by the terminal in a time domain, that is, the N detection signals and the high level of the radio frequency signal are set in a staggered manner in the time domain.
The time domain is also called time domain, i.e. the horizontal axis is time and the vertical axis is the variation of the signal. The N detection signals are not overlapped with the high level of the radio frequency signal transmitted by the terminal in the time domain, that is, for the same time axis, the N detection signals are not overlapped with the high level of the radio frequency signal.
In the N detection signals, the time domain widths of the detection signals may be the same or different, and are specifically set according to actual situations, which is not limited herein. When N is greater than 3, the time intervals between two adjacent detection signals in the same period of the touch scan transmission signal may be the same or different, and are specifically set according to an actual situation, which is not limited herein. In the present embodiment, N is preferably 2, and when N is 2 and the time domain widths of the 2 detection signals are the same, the complexity in setting the detection signals can be reduced.
And 102, receiving through a receiving end to obtain N touch scanning receiving signals respectively corresponding to the N detection signals.
Specifically, the receiving end may be a receiving end of the touch screen control module. The terminal is provided with a TP module, the TP module is connected with a TP control chip, and the TP control chip comprises a touch screen control module transmitting end (namely a TX end) and a touch screen control module receiving end (namely an RX end). And the TX end sends a touch scanning sending signal to the TP module, and after the touch scanning sending signal enters the TP module, the TP module generates an RX signal and sends the RX signal to an RX end of the TP control chip. N touch scan reception signals respectively corresponding to the N detection signals can be obtained by an RX signal. One detection signal corresponds to one touch scan reception signal.
And 103, if the absolute values of the N difference values are all greater than respective preset thresholds, responding to a trigger operation by the touch screen, where the N difference values are the difference values between each detection signal in the N detection signals and the respective corresponding touch scanning receiving signals, and each difference value corresponds to a respective preset threshold.
Specifically, the detection signal and the corresponding touch scan reception signal are subjected to difference operation, so that N differences are obtained. And correspondingly setting a preset threshold value for each difference value. For example, when the touch scan transmission signal includes 2 detection signals, a first preset threshold is set for a difference value between the first detection signal and the corresponding first touch scan reception signal; and setting a second preset threshold value for the difference value of the second detection signal and the corresponding second touch scanning receiving signal. The respective preset thresholds corresponding to each difference value may be the same or different, and may be specifically set according to an actual situation, which is not limited herein.
Preferably, when N is 2 and the time domain widths of the 2 detection signals are the same, the respective preset thresholds corresponding to each difference value are the same, so as to reduce the setting complexity of the preset thresholds.
And when the absolute values of the N difference values are all larger than the respective preset threshold value, the touch screen responds to the trigger operation. For example, when the touch scan sending signal includes 2 detection signals, if the absolute value of the difference between the first detection signal and the corresponding first touch scan receiving signal is greater than a first preset threshold, and the absolute value of the difference between the second detection signal and the corresponding second touch scan receiving signal is greater than a second preset threshold, the touch screen responds to the trigger operation. Like this, detect 2 detected signal simultaneously, only when the difference that obtains through 2 detected signal all surpasss respective preset threshold value, just can deem to have touch operation on the touch-sensitive screen, the touch-sensitive screen needs to respond this touch operation. And when the touch screen responds to the touch operation, sending the position information of the triggered point of the touch screen to a central processing unit of the terminal.
In this embodiment, since the N detection signals included in the touch scan transmission signal are not overlapped with the high level of the radio frequency signal, at least one detection signal in each scan period can completely avoid the radio frequency signal (i.e., the detection signal is not overlapped with the radio frequency signal in the time domain), so as to avoid the touch screen from being interfered by the radio frequency signal, and reduce the probability of false triggering of the touch screen due to the interference of the radio frequency signal.
The touch screen response triggering method in the embodiment is applied to a terminal which transmits radio frequency signals and is provided with a touch screen.
In this embodiment of the present invention, the terminal may be a mobile terminal, for example: the terminal may also be another functional module that needs to transmit a radio frequency signal and has a periodic scanning detection signal.
The touch screen response triggering method of the embodiment of the invention transmits a touch scanning sending signal through a transmitting terminal, wherein a high level part of the touch scanning sending signal comprises N detection signals, wherein N is an integer greater than or equal to 2, and each detection signal in the N detection signals is not overlapped with the high level of a radio frequency signal transmitted by a terminal in a time domain; receiving through a receiving end to obtain N touch scanning receiving signals respectively corresponding to the N detection signals; and if the absolute values of the N difference values are greater than respective preset threshold values, responding to a trigger operation by the touch screen, wherein the N difference values are the difference values between each detection signal and the corresponding touch scanning receiving signal in the N detection signals, and each difference value corresponds to the respective preset threshold value, so that the interference of the radio frequency signal of the terminal to the response trigger of the touch screen can be effectively avoided, the probability of false trigger caused by the interference of the touch screen is reduced, and the experience of a terminal user is enhanced.
In addition, the touch screen response triggering method in the embodiment is simple to implement, does not need to additionally increase hardware cost, and can effectively reduce the interference probability of the radio frequency signal on the touch screen response triggering.
Further, as shown in fig. 2, the present invention further provides an embodiment, before step 101, further comprising:
and step 104, acquiring the radio frequency signal transmitted by the terminal.
If the detection signal on the touch scan transmission signal can avoid the radio frequency signal, the detection signal needs to be adjusted according to the radio frequency signal, so in this step, the radio frequency signal transmitted by the terminal needs to be acquired, for example, time domain information of the radio frequency signal is acquired, and the time domain information of the radio frequency signal includes a time domain width of the radio frequency signal and a signal interval duration between two adjacent high levels. The radio frequency signal is a pulse signal, and the signal interval duration between two adjacent high levels is greater than the time domain width.
And 105, setting the touch scanning sending signal according to the radio frequency signal. That is, the detection signal included in the touch scan transmission signal is set according to the time domain information of the radio frequency signal.
Specifically, according to the radio frequency signal, the time domain widths of the N detection signals and the time intervals between the detection signals are adjusted, so that the N detection signals of the touch scan transmission signal and the high level of the radio frequency signal are not overlapped in the time domain.
The N detection signals are set to be not overlapped with the high level of the radio frequency signal in the time domain, and whether the touch screen should respond to the trigger or not can be obtained by judging the detection signals in the subsequent steps. The time domain widths of the N detection signals and the time intervals among the detection signals are adjusted, so that the detection signals are not overlapped with the high levels of the radio frequency signals in the time domain, and at least one detection signal in each scanning period can completely avoid the interference of the radio frequency signals, thereby avoiding the condition of false triggering when the touch screen is interfered by the radio frequency signals.
Further, an embodiment of the present invention provides a method for setting a detection signal: the N detection signals satisfy the following expression:
wherein, TiRepresents the time domain width, delta T, of the ith detection signal in the same period of the touch scan transmission signaljIndicating the j signal interval duration on the same period of the touch scanning sending signal, wherein the signal interval durationFor the time length between two adjacent detection signals, Δ Y represents the signal interval time length between two adjacent high levels in the radio frequency signal, Y represents the time domain width of one high level of the radio frequency signal, and Δ Tj＞Y。
In this embodiment, when the detection signals satisfy the above expression, the N detection signals may be staggered from the radio frequency signal, so as to avoid interference of the touch screen by the radio frequency signal when responding to the trigger. The radio frequency signal is a pulse signal.
In the above expression, the time domain widths of the N detection signals may be equal or unequal, and when N is greater than 3, the interval durations between two adjacent detection signals in the same period may be equal or unequal. When N is equal to 2 and the time domain widths of the 2 detection signals are equal, the two detection signals satisfy: as shown in fig. 3, where 2T + Δ T is Δ Y, reference numeral 1 denotes a first detection signal, reference numeral 2 denotes a second detection signal, reference numeral 3 denotes a touch scan transmission signal, and reference numeral 4 denotes a radio frequency signal. At this time, the 2 detection signals are simultaneously staggered with the radio frequency signal, i.e. the 2 detection signals just do not overlap with the high level of the radio frequency signal. Further, when the 2T + Δ T is decreased, as shown in fig. 3, i.e. the interval between the first detection signal and the second detection signal is decreased, or the time domain width of the first detection signal (or the second detection signal) is decreased, the two detection signals are far away from the high level part of the rf signal, so that the 2 detection signals are prevented from being interfered by the rf signal.
Further, another way of setting the detection signal is provided in the embodiments of the present invention: in the case where N is equal to 2, the detection signal satisfies the following expression:
Δ T is not less than mY + (m-1) Δ Y, and T11+T12+ΔT≤(m-1)Y+mΔY
Wherein, T11And T12Respectively representing the time domain widths of two detection signals in the same period of the touch scanning sending signal, wherein Δ T represents the signal interval duration of the two detection signals in the same period of the touch scanning sending signal, Δ Y represents the signal interval duration between two adjacent high levels in the radio frequency signal, and Y represents a high level of the radio frequency signalThe time domain width of the level, Δ Y > Y, Δ T > Y, m is an integer greater than or equal to 2.
As shown in fig. 4 and 5, m is equal to 2, and the time domain widths of the 2 detection signals are equal. Reference numeral 1 denotes a first detection signal, reference numeral 2 denotes a second detection signal, reference numeral 3 denotes a touch scan transmission signal, and reference numeral 4 denotes a radio frequency signal. The detection signal satisfies that Δ T ≧ 2Y + Δ Y (as shown in FIG. 4), and 2T + Δ T ≦ Y +2 Δ Y (as shown in FIG. 5), so that the detection signal is not interfered by the RF signal.
