Example 1
According to an embodiment of the present invention, there is provided an embodiment of a control method of a terminal, it should be noted that the steps shown in the flowchart of the figure may be executed in a computer system such as a set of computer executable instructions, and that although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in an order different from that here.
Fig. 1 is a flowchart of a control method of a terminal according to an embodiment of the present invention, as shown in fig. 1, the method including the steps of:
step S102, acquiring a preset static picture.
Specifically, the preset static image may be a white screen, a horizontal stripe, a multi-wave group, or the like, and the static images may generate co-channel interference on the operation of the touch screen, that is, when the preset static image is displayed on the display screen, an abnormality may occur in the touch function of the touch screen, such as misinformation data.
In an optional embodiment, taking the terminal as an interactive intelligent device as an example, the preset static image may be stored in the interactive intelligent device, and the interactive intelligent device may adjust the operating frequency of the touch screen according to the stored static image, so as to avoid interference to the touch screen when the display screen displays the preset static image.
Step S104, whether the current picture displayed by the display device of the terminal is a static picture is detected.
Specifically, the Display device may be an LCD (Liquid Crystal Display) or an LED Display, and when the Display device displays the preset static image, the driving circuit of the Display device may operate in a wider frequency band, and since the touch device may operate in the frequency band, the operation of the touch device may be affected.
And step S106, if the current picture is a static picture, controlling the touch device of the terminal to adjust the working frequency of the touch device.
In the above steps, if the current frame is a preset static frame, it is determined that the display device will generate co-channel interference on the operation of the touch device, and therefore the touch device is controlled to adjust the working frequency so as to avoid the working frequency when the display device displays the static frame.
In an optional embodiment, taking an interactive intelligent device as an example, the interactive intelligent device realizes display of the device through an LCD, and realizes a touch function through a capacitive screen. In the running process of the interactive intelligent device, the MCU of the device detects whether a picture displayed by the LCD is a preset static picture in real time, and if the picture is detected that the LCD displays the preset static picture, the MCU controls the capacitive screen to carry out frequency hopping, so that the capacitive screen avoids the interference of the LCD.
As can be seen from the above, in the embodiments of the present application, the preset static image is obtained, whether the current image displayed by the display device of the terminal is the static image is detected, and if the current image is the static image, the touch device of the terminal is controlled to adjust the operating frequency of the touch device. According to the scheme, whether the current displayed picture of the display screen is the preset static picture or not is judged, whether the current displayed content of the display screen can interfere with the touch screen or not is determined, and frequency hopping control is carried out on the touch screen under the condition that the current displayed picture of the display screen is the preset static picture, so that the working frequency of the touch screen is enabled to be away from the frequency band where the preset static picture is displayed by the display screen, interference avoidance is achieved, the effect of improving the signal-to-noise ratio of the touch screen is achieved, and the technical problem that in the prior art, the stability of the capacitive screen is difficult to adapt to various pictures of the display screen, and the touch function of the capacitive screen can be interfered by the display screen is solved.
As an alternative embodiment, acquiring a preset still picture includes: acquiring an image signal corresponding to a static picture; and/or acquiring the frequency band of the display device when the display device displays the static picture.
Specifically, the image signal may be an electrical signal corresponding to a static image, and the frequency band is a frequency band in which the display device operates when the display device displays the static image, that is, a frequency band that needs to be avoided by the touch device.
In an alternative embodiment, still taking the interactive intelligent device as an example, the image signal of the preset static picture may be collected, and the image signal of the preset static picture may be stored in the interactive intelligent device.
In another alternative embodiment, still taking the interactive intelligent device as an example, when the interactive intelligent device displays a preset static picture, a frequency band in which the display device operates may be detected, and the frequency band may be stored in the interactive intelligent device.
It should be noted that, if the image signal of the preset still picture is acquired, since the image signal does not change with the change of the terminal, the same image signal is stored in all terminals; if the frequency bands are obtained, the working frequency bands of the terminals of different models when displaying the preset static picture are not necessarily the same, so that the working frequency bands of the terminals of different models when displaying the preset static picture need to be obtained and correspondingly stored.
As an alternative embodiment, detecting whether a current picture displayed by a display device of a terminal is a static picture includes: detecting an image signal of a current picture; comparing the image signal of the current picture with the image signal of the static picture; and if the image signal of the current picture is matched with the image signal of the static picture, determining that the current picture is a preset static picture.
In the above scheme, whether the currently displayed picture is a preset still picture is determined by an image signal of the current image displayed by the display device.
In an optional embodiment, when it is determined that the display device displays the static image, the image signal of the current image is compared with the image signal of the preset static image to determine whether the current image is the preset static image. For example, still taking the interactive intelligent device as an example, the processor of the terminal detects whether a currently displayed picture is a static picture, if the display device displays a dynamic picture (e.g., a video), the comparison is not performed, if the display device currently displays a static picture, an image signal of the current picture is acquired and compared with an image signal of a preset static picture, and if the image signal of the current picture is the same as the image signal of the preset static picture, the current picture is determined to be the preset static picture.
As an alternative embodiment, detecting whether a current picture displayed by a display device of a terminal is a static picture includes: detecting the current working frequency when the display device displays the current picture; judging whether the current working frequency belongs to a frequency band; and if the current working frequency belongs to the frequency band, determining that the current picture is a preset static picture.
In the above scheme, whether the current picture displayed by the display device is a preset static picture is judged according to the working frequency of the current display device.
In an optional embodiment, still taking the interactive intelligent device as an example, the processor of the interactive intelligent device acquires the current operating frequency of the display device in real time, and determines whether the current operating frequency belongs to the operating frequency band when the display device displays the preset static image, and if so, determines that the current image is the static image.
As an optional embodiment, if the current frame is a static frame, controlling the touch device of the terminal to adjust the operating frequency of the touch device includes: sending a frequency hopping instruction to the touch device; and controlling the touch device to adjust the working frequency of the touch device according to the frequency hopping instruction, wherein the touch device hops from the first working frequency to a second working frequency according to the frequency hopping instruction, and the second working frequency does not belong to the frequency band of the display device when the display device displays a preset static picture.
The touch device may be a capacitive screen, and still take an interactive intelligent device as an example, where a processor of the interactive intelligent device needs to control the touch device to perform frequency hopping under the condition that a current picture is determined to be a preset static picture, so as to avoid co-frequency interference of the display device on the touch device.
In the above steps, the terminal processor sends the frequency hopping instruction to the touch device to trigger the touch device to perform frequency hopping. In an alternative embodiment, the frequency hopping command sent by the terminal processor to the touch device may be a continuous high level output by the designated port, and the frequency hopping command is executed after the touch device detects the high level of the designated port.
The touch device hops from the original first working frequency to the second working frequency, and the second working frequency does not belong to the frequency band where the display device displays the preset static picture, so that when the touch device hops to the second working frequency, the touch device avoids the interference of the display device, the signal-to-noise ratio is improved, and the condition of misinformation of data is avoided.
As an optional embodiment, if the current frame is a static frame, after the touch device of the control terminal adjusts the operating frequency of the touch device, the method further includes: detecting the duration of the frequency hopping instruction by the touch device; if the continuous time of the frequency hopping instruction exceeds the preset time, acquiring a reference signal again, wherein the reference signal is used for determining a third working frequency, and the third working frequency does not belong to a frequency band in which the display device operates when the display device displays a preset static picture; the touch device operates at a third operating frequency.
In the above scheme, the hopping command is a continuous control signal, for example, the hopping command may be a continuous high level. If the display device displays the preset static picture all the time, the frequency hopping instruction exists all the time.
The touch device may have a plurality of selectable operating frequencies, and if the duration of the frequency hopping instruction exceeds the preset time, it indicates that the time for the display device to display the preset static image exceeds the preset time, so that in order to stably operate the touch device, the touch device needs to be reset, and the reference signal needs to be obtained again to obtain a new operating frequency, that is, the third operating frequency.
In an optional embodiment, the preset time may be 5s, and still take the interactive intelligent device as an example, when the user uses the interactive intelligent device to display the content, a static picture is used as a background, because the display time is long, the time required by the frequency hopping instruction exceeds 5s, in order to make the working signal of the touch device more stable, the touch device performs data resetting to reacquire the reference signal, obtain the third working frequency, and then work at the third working frequency, which avoids the interference caused by the display device and can stably operate.
It should be noted that, if the terminal is restarted, the touch device may still operate according to a default operating frequency, that is, the first operating frequency.
As an optional embodiment, if the current frame is a static frame, after the touch device of the control terminal adjusts the operating frequency of the touch device, the method further includes: detecting whether the frequency hopping instruction stops; and if the frequency hopping instruction is detected to stop, controlling the touch device to recover from the second working frequency to the first working frequency.
In the above step, if the frequency hopping command is stopped, it indicates that the display device is switched from the static image to another image that does not generate co-channel interference with the touch device, so that the touch device can be restored from the second operating frequency to the first operating frequency.
Fig. 2 is a schematic diagram of a touch device for avoiding co-channel interference of a display device according to an embodiment of the invention. Still taking the interactive intelligent device as an example, firstly, the working frequency of the display screen displaying the preset static picture is obtained, and the MCU of the interactive intelligent device generates the control logic according to the working frequency and stores the control logic in the memory.
The display screen displays the picture processed by the image signal processing unit under the driving of the display screen driving unit, in the process, the MCU detects the current working frequency of the display screen in real time, whether a conflict risk exists is judged according to the current working frequency (if the current working frequency is the same as the working frequency when the prestored display screen displays the preset static picture, the conflict risk exists), if the conflict risk exists, the MCU sends a frequency hopping instruction to the touch device, and if the conflict risk does not exist, the frequency hopping control is not carried out.
After the processing unit of the touch screen receives the frequency hopping instruction, the capacitance control unit executes frequency hopping action (the target frequency of frequency hopping can be acquired from the memory), and when the frequency hopping instruction is received, the processing unit also records the duration of the frequency hopping instruction, if the duration is more than 5s, the processing unit executes resetting action, acquires the reference signal again, and sends the acquired reference signal to the touch screen, so that the touch screen works according to the acquired basic signal. And if the frequency hopping instruction stops, the control unit of the touch screen restores the default frequency (the default frequency can be acquired from the memory), and executes resetting through the touch screen to acquire the reference signal again so that the touch screen operates according to the default frequency.

Specifically, the preset static image may be a white screen, a horizontal stripe, a multi-wave group, or the like, and the static images may generate co-channel interference on the operation of the touch screen, that is, when the preset static image is displayed on the display screen, an abnormality may occur in the touch function of the touch screen, such as misinformation data.
The Display device may be a Liquid Crystal Display (LCD) or an LED Display, and when the Display device displays the predetermined static image, the driving circuit of the Display device may operate in a wider frequency band, and since the touch device may operate in the frequency band, the operation of the touch device may be affected.
In the above steps, if the current frame is a preset static frame, it is determined that the display device will generate co-channel interference on the operation of the touch device, and therefore the touch device is controlled to adjust the working frequency so as to avoid the working frequency when the display device displays the static frame.
In an optional embodiment, taking an interactive intelligent device as an example, the interactive intelligent device realizes display of the device through an LCD, and realizes a touch function through a capacitive screen. In the running process of the interactive intelligent device, the MCU of the device detects whether a picture displayed by the LCD is a preset static picture in real time, and if the picture is detected that the LCD displays the preset static picture, the MCU controls the capacitive screen to carry out frequency hopping, so that the capacitive screen avoids the interference of the LCD.
In step S304, the touch device adjusts the operating frequency of the touch device according to the control signal.
In an optional embodiment, taking the terminal as an interactive intelligent device as an example, the preset static image may be stored in the interactive intelligent device, and the interactive intelligent device may adjust the operating frequency of the touch screen according to the stored static image, so as to avoid interference to the touch screen when the display screen displays the preset static image.
As can be seen from the above, in the above embodiments of the present application, the touch device of the terminal receives a control signal sent by the terminal processor, where the terminal processor obtains a preset static picture and detects whether a current picture displayed by the display device of the terminal is the static picture, and if the current picture is the static picture, sends a control signal to the touch device, where the control signal is used to control the touch device of the terminal to adjust a working frequency of the touch device, and the touch device adjusts the working frequency of the touch device according to the control signal. According to the scheme, whether the current displayed picture of the display screen is the preset static picture or not is judged, whether the current displayed content of the display screen can interfere with the touch screen or not is determined, and frequency hopping control is carried out on the touch screen under the condition that the current displayed picture of the display screen is the preset static picture, so that the working frequency of the touch screen is enabled to be away from the frequency band where the preset static picture is displayed by the display screen, interference avoidance is achieved, the effect of improving the signal-to-noise ratio of the touch screen is achieved, and the technical problem that in the prior art, the stability of the capacitive screen is difficult to adapt to various pictures of the display screen, and the touch function of the capacitive screen can be interfered by the display screen is solved.
As an alternative embodiment, the control signal includes a frequency hopping command, and after the touch device adjusts the operating frequency of the touch device according to the control signal, the method further includes: detecting the duration of the frequency hopping instruction by the touch device; if the continuous time of the frequency hopping instruction exceeds the preset time, acquiring a reference signal again, wherein the reference signal is used for a third working frequency, and the third working frequency does not belong to a frequency band in which the display device operates when the display device displays a preset static picture; the touch device operates at a third operating frequency.
In the above scheme, the hopping command is a continuous control signal, for example, the hopping command may be a continuous high level. If the display device displays the preset static picture all the time, the frequency hopping instruction exists all the time.
The touch device may have a plurality of selectable operating frequencies, and if the duration of the frequency hopping instruction exceeds the preset time, it indicates that the time for the display device to display the preset static image exceeds the preset time, so that in order to stably operate the touch device, the touch device needs to be reset, and the reference signal needs to be obtained again to obtain a new operating frequency, that is, the third operating frequency.
In an optional embodiment, the preset time may be 5s, and still take the interactive intelligent device as an example, when the user uses the interactive intelligent device to display the content, a static picture is used as a background, because the display time is long, the time required by the frequency hopping instruction exceeds 5s, in order to make the working signal of the touch device more stable, the touch device performs data resetting to reacquire the reference signal, obtain the third working frequency, and then work at the third working frequency, which avoids the interference caused by the display device and can stably operate.
