[0043] The following describes the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. The terms used in the implementation method section of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application.

[0044] The embodiments of the present application are described below in conjunction with the accompanying drawings. Those skilled in the art will appreciate that, with the development of technology and the emergence of new scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, which is only to describe the distinction mode adopted by the objects of the same attributes when describing in the embodiments of the present application. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, so that the process, method, system, product or equipment comprising a series of units need not be limited to those units, but may include other units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0046] The present application discloses a communication control method, which is applied to an electronic device including a touch surface and a display screen, and its flow chart is as follows: Figure 1 As shown, including:

[0047] Step S11, obtaining status information of the input device via the communication interface;

[0048] Step S12: determining the quality of an uplink signal from the touch surface of the electronic device to the input device based on the state information;

[0049] Step S13: determining the uplink signal transmission state of the target area of ​​the touch surface based on the uplink signal quality.

[0050] The stylus is mainly used in electronic devices with a touch surface, such as smart phones, tablet computers, etc. The stylus interacts with the touch surface by simulating the electric field of the human body, thereby achieving precise touch operation of the electronic device.

[0051] The stylus usually controls the touch surface on the electronic device as follows: the receiving electrode Rx on the stylus receives the uplink signal sent by the touch surface. After the stylus recognizes the correct uplink signal, it outputs the corresponding downlink signal to the touch surface. The touch surface detects the downlink signal to determine the decoding coordinates and pressure, thereby realizing two-way communication between the stylus and the electronic device.

[0052] However, during the writing process of the stylus, the uplink signal sent by the touch surface may be interfered by various factors, such as: the palm touching the touch surface, etc., which will affect the quality of the uplink signal and thus affect the touch control of the electronic device by the stylus.

[0053] Based on this, in this scheme, the status information of the input device is obtained, and its status information can reflect the quality of the uplink signal from the touch surface of the display screen to the input device. After determining the uplink signal quality, the uplink signal sending status of the target area of ​​the display screen is adjusted to avoid interference to the target area of ​​the display screen, which affects the quality of the uplink signal sent from the touch surface of the display screen to the input device, thereby affecting the two-way communication between the input device and the electronic device, resulting in the problem of affecting the touch control of the electronic device.

[0054] In this embodiment, the electronic device is an electronic device including a touch surface and a display screen. The touch surface may be located on the display screen. The touch surface may be a surface on the electronic device for receiving a user's touch operation, such as: the user moves or clicks on the touch surface with a hand or a stylus, and the electronic device can perform corresponding processing based on the movement or clicking of the hand or the stylus on the touch surface. The electronic device may be: a mobile phone, a tablet computer, or a laptop computer with a stylus, or may be located at different positions from the display screen, such as: a tablet computer capable of externally touching the input area; the input device may be a stylus, or may be other devices capable of inputting on the touch surface to control the electronic device.

[0055] When the input device writes on the touch surface of the display screen of the electronic device, the touch surface will send an uplink signal to the input device. After the input device detects the uplink signal, it will output a corresponding downlink signal to the touch surface. Thereafter, writing or control of the electronic device is achieved based on the downlink signal received by the touch surface. The state of the touch surface will affect the quality of the uplink signal. When the quality of the uplink signal is affected, the input device can sense that the quality of the uplink signal is affected. Therefore, the state of the touch surface can be monitored directly based on the state of the input device. The state of the input device is generated based on the quality of the uplink signal detected by it, and can characterize the quality of the uplink signal, such as: the state information of the input device is: the signal strength of the uplink signal is low, the signal strength of the uplink signal is medium, the signal strength of the uplink signal is strong, etc., or the state information of the input device is directly the strength value of the uplink signal.

[0056] After the input device generates status information based on the quality of the detected uplink signal, the input device can transmit the status information to the electronic device through the communication interface, so that the electronic device can determine based on the received status information whether the state of the touch surface affects the communication between the input device and the electronic device and the touch surface needs to be adjusted.

[0057] The communication interface between the input device and the electronic device may be a Bluetooth communication interface, that is, the Bluetooth communication interface of the input device is paired with the Bluetooth communication interface of the electronic device in advance, and when the input device generates status information, the input device sends the status information to the electronic device through the paired Bluetooth communication interface, so that the electronic device can receive the status information of the input device, so that the electronic device can make corresponding adjustments based on the status information;

[0058] Alternatively, the communication interface between the input device and the electronic device may also be: a WiFi communication interface, that is, a connection is established between the input device and the electronic device in advance through the WiFi communication interface, and when the input device generates status information, the input device sends the status information to the electronic device through the WiFi communication interface, so that the electronic device can receive the status information of the input device, so that the electronic device can make corresponding adjustments based on the status information.

[0059] Among them, the communication interface may include a first communication interface and a second communication interface, the first communication interface is located on the input device, and the second communication interface is located on the electronic device. If the input device sends status information to the electronic device through the communication interface, the input device actually sends the status information to the electronic device through the first communication interface and the second communication interface.

[0060] Of course, the communication interface may be of other types, which are not specifically limited here.

[0061] After the electronic device obtains the status information sent by the input device, it analyzes the status information to determine the quality of the uplink signal from the touch surface of the display screen to the input device. For example, if the status information indicates that the uplink signal quality is poor, the electronic device analyzes the status information after receiving the status information to determine that the uplink signal quality is poor.

[0062] Alternatively, the electronic device pre-stores an uplink signal strength standard value k, and when the uplink signal strength is greater than or equal to the uplink signal strength standard value, it can be determined that the uplink signal strength is strong, and when the uplink signal strength is less than the uplink signal strength standard value, it can be determined that the uplink signal strength is poor. If the state information is that the uplink signal strength is a, and it is determined that a>k, it can be determined that the current uplink signal quality is good; if it is determined that a<k, it can be determined that the current uplink signal quality is poor.

[0063] After the uplink signal quality is determined, the state of the area of ​​the touch surface that affects the uplink signal quality may be determined based on the uplink signal quality.

[0064] The area on the touch surface that affects the uplink signal quality can be a target area. The state of the target area is determined based on the uplink signal quality. Specifically, the sending state of the uplink signal in the target area is determined, that is, the state in which the uplink signal is sent in the target area, which will affect the uplink signal quality. Therefore, after determining the uplink signal quality, the sending state of the uplink signal in the target area can be adjusted in the reverse direction so that the uplink signal quality can meet the requirements.

[0065] The communication control method disclosed in this embodiment is applied to an electronic device including a touch surface and a display screen, and obtains the status information of the input device via a communication interface; determines the quality of the uplink signal from the touch surface of the electronic device to the input device based on the status information; and determines the uplink signal sending state of the target area of ​​the touch surface based on the uplink signal quality. After obtaining the status information of the input device, this scheme can determine the uplink signal quality from the touch surface of the electronic device to the input device based on the status information, and thereby determine the uplink signal sending state of the target area of ​​the touch surface, so as to adjust the uplink signal sending state of at least part of the area on the touch surface based on the status information of the input device, avoid the influence of the target area on the touch surface on the uplink signal quality, and ensure accurate control of the electronic device through the input device.

[0066] This embodiment discloses a communication control method, which is applied to an electronic device including a touch surface and a display screen. The flow chart is as follows: Figure 2 As shown, including:

[0067] Step S21, obtaining status information of an input device via a communication interface;

[0068] Step S22: determining the quality of an uplink signal from the touch surface of the electronic device to the input device based on the state information;

[0069] Step S23, determining a target area of ​​the touch surface;

[0070] Step S24: Determine the uplink signal transmission status of the target area based on the uplink signal quality.

[0071] The target area may be a complete area on the touch surface for sending uplink signals, that is, the complete area of ​​the touch surface can send uplink signals, then the state of each area on the touch surface will affect the quality of the uplink signal, therefore, the sending state of the uplink signal in each area on the touch surface may be adjusted based on the uplink signal quality determined by the state information fed back by the input device, so as to implement feedback adjustment of the uplink signal quality, ensure the quality of the uplink signal transmitted from the electronic device to the input device, and ensure the communication effect between the electronic device and the input device;

[0072] It can also be: the target area is a partial area on the touch surface that can send uplink signals, that is, the partial area of ​​the touch surface affects the uplink signal quality. Therefore, after determining the current uplink signal quality, the state of the partial area of ​​the touch surface that affects the uplink signal quality is adjusted so that the subsequent uplink signal quality will not be affected by the partial area of ​​the touch surface, thereby ensuring the communication effect, wherein the current uplink signal quality is the uplink signal quality determined based on the status information fed back by the input device, and the subsequent uplink signal quality is the uplink signal quality determined based on the status information fed back by the input device after adjusting the state of the partial area of ​​the touch surface.

[0073] The determination of the target area may be:

[0074] Detecting capacitance change information corresponding to the touch surface; if it is determined that there is an area where capacitance changes in the capacitance corresponding to the touch surface, and the area of ​​the area where capacitance changes is greater than a target threshold, determining the area as a target area.

[0075] like Figure 3 As shown, it is a schematic diagram of the influence of the target area on the quality of the uplink signal, including: an input device 31 and a touch surface 32 of the electronic device. When inputting on the touch surface of the electronic device through the input device, the user holds the input device, and the other arm or palm of the user touches the area of ​​the touch surface, that is, the target area 33. The human body will be connected to the input device as a large capacitor, and connected to the inverting input terminal of the receiving amplifier inside the input device; and the sensing component of the input device (such as: the tip of the stylus) receives a normal uplink signal when inputting on the touch surface. The normal uplink signal enters the positive input terminal of the receiving amplifier inside the input device. The signal received at the positive input terminal of the receiving amplifier is differentially processed with the signal received at its inverting input terminal. The processed signal is used as the uplink signal finally received by the input device, and is weakened by the signal input at the inverting input terminal, thereby affecting the quality of the uplink signal. Then the input device generates status information and transmits it to the electronic device.

[0076] After receiving the status information, the electronic device determines that the uplink signal quality is affected. At this time, the electronic device determines the target area of ​​the touch surface that affects the uplink signal quality, that is, Figure 3 In the area 31 of the touch surface touched by the other arm or palm of the user, if the user inputs on the touch surface of the electronic device with the handheld input device, the other arm or palm of the user does not touch the touch surface, then the capacitance of the human body will not be connected to the input device, and no uplink signal will be input to the inverting input terminal of the receiving amplifier of the input device. Therefore, it is determined Figure 3 The area 31 of the touch surface touched by the other arm or palm of the user is the target area.

[0077] The position of the target area on the touch surface may be determined through capacitance change information corresponding to the touch surface.

[0078] When the user's palm or arm touches the touch surface, the capacitance of the area on the touch surface where the palm or arm touches will change. In addition, as the tip of the stylus pen writes on the touch surface, the capacitance at the location of the tip on the touch surface will also change. Moreover, the area of ​​the touch surface where the palm or arm touches must be larger than the area corresponding to the tip of the stylus pen on the touch surface. Therefore, in this embodiment, if it is determined that there is an area on the touch surface where the capacitance changes, it is necessary to further determine whether the area on the touch surface where the capacitance changes is greater than the target threshold. If it is not greater than the target threshold, it indicates that the area on the current touch surface where the capacitance changes is the area corresponding to the tip of the stylus pen. If it is greater than the target threshold, the area greater than the target threshold can be determined as the target area.

[0079] Alternatively, the target area may be determined as follows:

[0080] The temperature change information of the touch surface is detected, and if it is determined that there is an area on the touch surface where the temperature has changed, the area on the touch surface where the temperature has changed is determined as a target area.

[0081] When the sensing component of the input device inputs on the touch surface, the temperature of the touch surface does not change; however, when the user's palm or arm is placed on the touch surface, the temperature of the human body surface will affect the temperature of the touch surface, so at this time, the temperature of the touch surface will change.

[0082] When it is determined that the temperature of the touch surface has changed, it can be determined that a human body has touched the touch surface. In one embodiment, after determining the uplink signal quality based on the status information of the input device, the target area is determined, and the uplink signal generation state of the target area is determined based on the uplink signal quality. That is, in this embodiment, when it is determined that there is an area on the touch surface that affects the uplink signal quality, the step of determining whether the target area affecting the uplink signal quality is the area where the user's palm or arm is placed on the touch surface is executed. At this time, it is determined directly based on the temperature of the touch surface. This embodiment can further reduce the power consumption of the device.

[0083] The area where the touch surface temperature changes significantly is the target area, and the area where the touch surface temperature does not change significantly is the non-target area. The target area has nothing to do with the size of the area where the touch surface temperature changes significantly.

[0084] The communication control method disclosed in this embodiment is applied to an electronic device including a touch surface and a display screen, and obtains the status information of the input device via a communication interface; determines the uplink signal quality from the touch surface of the electronic device to the input device based on the status information; determines the target area of ​​the touch surface; and determines the uplink signal sending state of the target area based on the uplink signal quality. After determining the uplink signal quality based on the status information of the input device, this scheme determines the target area on the touch surface so as to determine the uplink signal sending state of the target area based on the uplink signal quality. The target area is the area of ​​the touch surface that affects the uplink signal quality. Adjustment of the uplink signal sending state of the target area achieves a reverse adjustment of the uplink signal quality, reduces the influence of the target area on the touch surface on the uplink signal quality, and ensures accurate control of the electronic device through the input device.

[0085] This embodiment discloses a communication control method, which is applied to an electronic device including a touch surface and a display screen. The flow chart is as follows: Figure 4 As shown, including:

[0086] Step S41, obtaining status information of an input device via a communication interface;

[0087] Step S42: determining the quality of an uplink signal from the touch surface of the electronic device to the input device based on the state information;

[0088] Step S43, when the uplink signal quality meets the target condition, the sending state of the uplink signal in the target area is controlled to switch from the first sending state to the second sending state, and the uplink signal in the target area has a first strength in the first sending state, and the uplink signal in the target area has a second strength in the second sending state, and the second strength is less than the first strength.

[0089] The input device sends status information to the electronic device through the communication interface. The electronic device determines the signal quality of the uplink signal from the touch surface of the electronic device to the input device based on the status information, and then determines whether the uplink signal quality meets the target conditions to determine whether it is necessary to adjust the sending status of the uplink signal in the target area.

[0090] Determine whether the uplink signal quality meets the target condition, and if it meets the target condition, adjust the sending state of the uplink signal in the target area. The target condition may be: lower than a certain strength threshold, or lower than a certain quality level, or within a certain strength range or quality range.

[0091] When it is determined that the uplink signal quality meets the target condition, the sending state of the uplink signal in the target area is controlled to switch from the first sending state to the second sending state, that is, before it is determined that the uplink signal quality meets the target condition, the sending state of the uplink signal in the target area is the first sending state, and after the uplink signal quality meets the target condition, the sending state of the uplink signal in the target area is the second sending state.

[0092] Wherein, regardless of whether the uplink signal quality meets the target condition, the sending state of the uplink signal in the area other than the target area on the touch surface remains unchanged, for example: the sending state of the uplink signal in the area other than the target area on the touch surface remains the first sending state unchanged.

[0093] When the uplink signal quality does not meet the target condition, that is, there is no target area on the touch surface that affects the uplink signal quality, at this time, the sending state of the uplink signal in all areas on the touch surface is the first sending state, so that the touch surface continues to send the uplink signal with a relatively large intensity; when the uplink signal quality meets the target condition, that is, there is a target area on the touch surface that affects the uplink signal quality, at this time, the area other than the target area on the touch surface still maintains the first sending state unchanged, and the target area sends the uplink signal in the second sending state. The signal strength of the uplink signal sent by the target area in the second sending state is less than the signal strength of the uplink signal sent by the target area in the first sending state, that is, the strength of the signal sent by the target area is controlled to be lower than the strength of the signal sent by other areas of the touch surface, so as to weaken the influence of the uplink signal sent by the target area on the uplink signal received by the sensing component of the input device, thereby improving the signal quality of the uplink signal received by the input device.

[0094] Further, when the uplink signal quality meets the target condition, the target area is controlled to be grounded so that the second strength is zero.

[0095] The signal strength of the uplink signal sent by the target area can be reduced to 0 directly, so that the target area does not send the uplink signal, thereby not causing any impact on the uplink signal received by the sensing component of the input device.

[0096] If the uplink signal strength sent by the target area is to be 0, the target area can be directly controlled to be grounded. Among them, the touch detection component corresponding to the touch surface can be composed of an M-row and N-column capacitor node array, and the electronic device can collect the capacitance value of each node in the capacitor node array. When the human body contacts the node, the capacitance value corresponding to the capacitor node will change. Based on the collected capacitance value change information, the target area can be determined, such as: the area of ​​the touch surface touched by the user's palm. After determining the target area, the capacitor nodes in the target area are directly controlled to be grounded, such as: the pins connected to the capacitors in the target area on the control chip where the processor of the electronic device is located are grounded, so that the grounding of the target area is achieved.

[0097] Further, when the uplink signal quality does not meet the target condition, the target area is not identified, or the uplink signal strength of the target area is restored.

[0098] If the uplink signal quality does not meet the target condition, it is determined whether there is a target area on the touch surface. If there is no target area, it indicates that the touch surface is in a state of normally sending uplink signals to the input device, and there is no signal that affects the uplink signal received by the sensing component of the input device. At this time, there is no target area, and there is no need to identify the target area. If there is a target area on the touch surface, it is determined that the uplink signal quality does not meet the target condition. At this time, since the sending state of the uplink signal of the target area is the second sending state, that is, the strength of the uplink signal sent by the target area is relatively small, it is necessary to control the sending state of the uplink signal of the target area to switch back to the first sending state, so that when the uplink signal quality does not meet the target condition and the target area disappears, all areas on the touch surface are in the first sending state, to ensure that any area on the touch surface can upload a strong uplink signal.

[0099] In the communication control method disclosed in this embodiment, the time of the uplink signal sent by the touch surface may correspond to the time of the downlink signal sent by the input device, such as Figure 5 As shown, it is a timing relationship diagram of the uplink signal and the downlink signal.

[0100] During the interaction cycle between the touch surface of the electronic device and the input device, the input device first receives the uplink signal of the touch surface, and then the input device sends the downlink signal. Therefore, after the touch surface sends the uplink signal, the touch surface switches to the receiving mode, such as: after the touch surface sends the uplink signal at time T0, the input device receives the uplink signal and determines that the uplink signal is reduced. At this time, the status information of the reduced signal strength of the uplink signal is sent to the electronic device through the communication interface between the input device and the electronic device. After receiving the status information, the electronic device controls the target area of ​​the touch surface to be grounded at time T1. On this basis, the signal strength of the uplink signal sent at time T1 received by the input device is restored.

[0101] After the signal strength of the uplink signal uplink received by the input device is restored, status information indicating that the uplink signal strength has been restored is output. After the electronic device receives the status information, it controls the target area of ​​the touch surface to release the grounding restriction, so that there is no grounded area on the touch surface of the electronic device, and any area of ​​the touch surface restores its previous sending state, so that the uplink signal sent by any area of ​​the touch surface has its default strength.

[0102] exist Figure 5 In a corresponding embodiment, after the touch surface sends an uplink signal uplink to the input device, the input device feeds back a corresponding downlink signal downlink to the touch surface based on the uplink signal, thereby realizing a corresponding relationship between the uplink signal and the downlink signal;

[0103] The communication control method disclosed in this embodiment is applied to an electronic device including a touch surface and a display screen, and obtains the status information of the input device via a communication interface; determines the quality of the uplink signal from the touch surface of the electronic device to the input device based on the status information; and when the uplink signal quality meets the target condition, controls the transmission state of the uplink signal of the target area to switch from the first transmission state to the second transmission state, wherein the uplink signal of the target area has a first strength in the first transmission state, and the uplink signal of the target area has a second strength in the second transmission state, and the second strength is less than the first strength. In this scheme, when it is determined that the uplink signal quality meets the target condition, the transmission state of the uplink signal of the target area is adjusted to reduce the strength of the uplink signal of the target area, thereby reducing the influence of the uplink signal of the target area on the uplink signal received by the sensing component of the input device, and improving the control accuracy of the input device over the electronic device.

[0104] This embodiment discloses a communication control method, which is applied to an input device. Figure 6 As shown, including:

[0105] Step S61: obtaining an uplink signal sent by an electronic device including a touch surface and a display screen;

[0106] Step S62: determining the uplink signal quality of the uplink signal;

[0107] Step S63: Generate status information based on the uplink signal quality, and send the status information to the electronic device via the communication interface.

[0108] The input device may be a stylus, which, when used on an electronic device including a touch surface and a display screen, can receive an uplink signal sent by the touch surface, and after obtaining the uplink signal, can generate a downlink signal based on the uplink signal, and feed the downlink signal back to the touch surface of the electronic device, so that the electronic device can determine the input of the input device to the electronic device based on the downlink signal.

[0109] After obtaining the uplink signal sent by the touch surface, the input device can first determine whether the uplink signal quality meets the target condition, that is, determine whether the uplink signal quality is lower than a specific strength threshold, or lower than a specific quality level, or within a specific strength range or quality range, etc.

[0110] If the input device determines that the quality of the uplink signal does not meet the target condition, a downlink signal may be directly generated based on the uplink signal, and the downlink signal may be sent to the touch surface of the electronic device;

[0111] If the input device determines that the uplink signal quality meets the target condition, it is necessary to generate status information, which can characterize that the uplink signal quality meets the target condition, and send the status information that can characterize that the uplink signal quality meets the target condition to the electronic device through the communication interface, so that the electronic device can determine the uplink signal quality after receiving the status information, and determine the uplink signal sending status of the target area of ​​the touch surface based on the uplink signal quality, and determine whether the uplink signal sending status of the target area needs to be adjusted.

[0112] When the input device determines that the uplink signal quality meets the target condition, while generating status information and sending the status information to the electronic device through the communication interface, a downlink signal is also generated based on the received uplink signal and sent to the touch surface of the electronic device. That is, even if the uplink signal quality received by the input device meets the target condition, the step of the input device generating and sending the downlink signal based on the uplink signal will not be interrupted but will continue. It is only to ensure that the subsequent downlink signal is not affected that the status information needs to be generated and sent to the electronic device so that the electronic device can adjust the uplink signal sending state of the target area of ​​the touch surface, so that the uplink signal received by the input device at the next moment is sent based on the touch surface after the uplink signal sending state of the target area is adjusted. At this time, the uplink signal quality no longer meets the target condition and will not affect the downlink signal.

[0113] Furthermore, when it is determined that the uplink signal quality meets the target condition, the sensing value of the sensing component of the input device can be further detected. Only when it is determined that the sensing value of the sensing component reaches the target sensing value, the status information is generated.

[0114] The sensing component is a component on the input device that is used to sense the touch surface of the electronic device to transmit an uplink signal or a downlink signal, such as the tip of a stylus pen.

[0115] The sensing value of the sensing component reaches the target sensing value, which can be: the input device has input on the touch surface of the electronic device. Only when the input device has input on the touch surface and it is determined that the uplink signal quality meets the target condition, will the status information be generated to eliminate the influence of the target area of ​​the touch surface on the uplink signal quality and avoid its influence on the uplink signal received by the sensing component.

[0116] Furthermore, after generating status information based on the uplink signal quality and sending the status information to the electronic device through the communication interface, the input device itself will also make corresponding adjustments, namely:

[0117] When it is determined that the uplink signal quality meets the target condition, the gain of the receiving amplifier of the control input device is adjusted from the first gain value to the second gain value, and the second gain value is greater than the first gain value.

[0118] Increasing the gain value of the receiving amplifier inside the input device can improve the quality of the signal received by the receiving amplifier and ensure the reception effect of the uplink signal. Even if there is a target area on the touch surface so that the uplink signal received by the sensing component of the input device is weakened by the uplink signal uploaded by the target area, the quality of the uplink signal finally received can be guaranteed.

[0119] The communication control method disclosed in this embodiment is applied to an input device to obtain an uplink signal sent by an electronic device including a touch surface and a display screen; determine the uplink signal quality of the uplink signal; generate status information based on the uplink signal quality, and send the status information to the electronic device via a communication interface. After the input device obtains the uplink signal sent by the electronic device, the scheme determines the uplink signal quality, generates status information representing the uplink signal quality, and sends it to the electronic device, so that the electronic device can adjust the uplink signal transmission state of at least a part of the touch surface of the electronic device based on the received status information, so as to improve the uplink signal transmission quality and improve the control accuracy of the input device over the electronic device.

[0123] The electronic device 72 obtains the status information of the input device via the second communication interface; determines the uplink signal quality from the touch surface of the electronic device to the input device based on the status information; and determines the uplink signal sending status of the target area of ​​the touch surface based on the uplink signal quality.
