第一方面，本申请实施例提供一种笔迹绘制方法，该方法的执行主体可以为电子设备，或者电子设备中的芯片，下述以执行主体为电子设备为例进行说明。电子设备包括触摸传感器TP sensor和第一传感器，所述第一传感器用于检测触控笔是否接触所述电子设备的触摸屏，所述TP sensor包含于所述触摸屏中。In the first aspect, the embodiment of the present application provides a handwriting drawing method. The execution subject of the method may be an electronic device, or a chip in the electronic device. The following description takes the electronic device as an example for execution. The electronic device includes a touch sensor TP sensor and a first sensor, the first sensor is used to detect whether the stylus touches the touch screen of the electronic device, and the TP sensor is included in the touch screen.

该笔迹绘制方法可以包括：电子设备响应于检测到所述第一传感器采集到信号，检测所述触控笔接触所述触摸屏的位置。因为第一传感器用于检测触控笔是否接触所述电子设备的触摸屏，因此当第一传感器采集到信号表征触控笔接触了触摸屏。电子设备检测所述触控笔接触所述触摸屏的位置的方式可以为：电子设备基于触摸屏中TP sensor的电容变化量的变化，获取触控笔接触所述触摸屏的位置。The handwriting drawing method may include: the electronic device detects a position where the stylus touches the touch screen in response to detecting the signal collected by the first sensor. Since the first sensor is used to detect whether the stylus touches the touch screen of the electronic device, when the first sensor collects a signal, it indicates that the stylus touches the touch screen. The manner in which the electronic device detects the position where the stylus touches the touch screen may be: the electronic device obtains the position where the stylus touches the touch screen based on the change in capacitance variation of the TP sensor in the touch screen.

电子设备检测到触控笔接触所述触摸屏的第一位置，可以获取所述第一位置的TPsensor的电容变化量阈值。其中，电子设备响应于检测到所述第一位置的TP sensor的电容变化量大于或等于所述第一位置的TP sensor的电容变化量阈值，执行绘制笔迹的操作，响应于检测到所述第一位置的TP sensor的电容变化量小于所述第一位置的TP sensor的电容变化量阈值，停止执行绘制笔迹的操作。The electronic device detects that the stylus pen touches the first position of the touch screen, and may acquire the capacitance variation threshold of the TP sensor at the first position. Wherein, the electronic device executes the operation of drawing handwriting in response to detecting that the capacitance variation of the TP sensor at the first position is greater than or equal to the capacitance variation threshold of the TP sensor at the first position, and in response to detecting that the capacitance variation threshold of the TP sensor at the first position is The capacitance variation of the TP sensor at a position is less than the capacitance variation threshold of the TP sensor at the first position, and the operation of drawing handwriting is stopped.

In this way, the electronic device can determine whether to perform the operation of drawing handwriting based on the capacitance change of the TP sensor at the first position and the capacitance change threshold of the TP sensor at the first position when the stylus touches the touch screen.

本申请实施例中，因为未将触摸屏采集的压感信号或加速度信号作为电子设备是否执行绘制笔迹的操作的判断条件，而是作为触发电子设备基于TP sensor的电容变化量判断是否执行绘制笔迹的操作的触发条件，无需蓝牙传输来自触控笔的压感信号，可以提高电子设备绘制笔迹的响应速度。本申请实施例中可以将压力阈值和三轴加速度的阈值设置为很小的值，如小于目前现有技术中的压力阈值，电子设备检测到微小的压力即可以响应，可以提高电子设备的控制精度。另外，本申请实施例中，可以在用户握持触控笔绘制笔迹，当触控笔接触到触摸屏时，触控笔开始出水，即电子设备执行绘制笔迹的操作，可以更好地模拟用户采用真实的笔进行书写，可以提高用户体验。In the embodiment of the present application, because the pressure-sensitive signal or the acceleration signal collected by the touch screen is not used as the judgment condition of whether the electronic device executes the operation of drawing handwriting, but as a trigger for the electronic device to judge whether to execute the drawing of handwriting based on the capacitance variation of the TP sensor The trigger condition of the operation does not require Bluetooth to transmit the pressure-sensitive signal from the stylus, which can improve the response speed of the electronic device to draw handwriting. In the embodiment of the present application, the pressure threshold and the triaxial acceleration threshold can be set to very small values, such as less than the pressure threshold in the current prior art, and the electronic device can respond when it detects a small pressure, which can improve the control of the electronic device precision. In addition, in the embodiment of the present application, the user can hold the stylus to draw handwriting. When the stylus touches the touch screen, the stylus starts to emit water, that is, the electronic device performs the operation of drawing handwriting, which can better simulate the user's use of Writing with a real pen can improve user experience.

下面对电子设备获取第一位置的TP sensor的电容变化量阈值的方式进行说明：The following describes how the electronic device obtains the capacitance change threshold of the TP sensor at the first position:

其一，电子设备响应于检测到第一传感器采集到信号，或者信号表征的信号值大于或等于信号值阈值时，可以检测触控笔接触所述触摸屏的第一位置和第一位置的TPsensor的电容变化量。电子设备可以基于所述第一位置的TP sensor的电容变化量和预设比例，获取所述第一位置的TP sensor的电容变化量阈值。示例性的，电子设备可以将第一位置的TP sensor的电容变化量和预设比例的乘积，作为第一位置的TP sensor的电容变化量阈值。应理解，预设比例可以为大于0小于1的值。First, when the electronic device detects that the first sensor has collected a signal, or when the signal value represented by the signal is greater than or equal to the signal value threshold, it can detect the first position where the stylus touches the touch screen and the first position of the TPsensor. capacitance change. The electronic device may acquire the capacitance change threshold of the TP sensor at the first position based on the capacitance change of the TP sensor at the first position and a preset ratio.

其二，电子设备中存储有所述触摸屏的至少一个位置的TP sensor的电容变化量阈值。应理解，在一种实施例中，电子设备可以预先下载该至少一个位置的TP sensor的电容变化量阈值，或者在用户历史操作触控笔绘制笔迹的过程中，电子设备可以获取且存储至少一个位置的TP sensor的电容变化量阈值。Second, the electronic device stores the capacitance variation threshold of the TP sensor in at least one position of the touch screen.

其中，电子设备可以响应于检测到所述触控笔接触所述触摸屏的第一位置，获取所述第一位置的TP sensor的电容变化量；基于所述第一位置的TP sensor的电容变化量和预设比例，获取所述第一位置的TP sensor的电容变化量阈值。同理的，电子设备可以响应于检测到所述触控笔接触所述触摸屏的第二位置，获取所述第二位置的TP sensor的电容变化量；基于所述第二位置的TP sensor的电容变化量和预设比例，获取所述第二位置的TPsensor的电容变化量阈值。如此，电子设备可以获取并存储至少一个位置的TP sensor的电容变化量阈值。Wherein, the electronic device may, in response to detecting that the stylus touches the first position of the touch screen, obtain the capacitance change amount of the TP sensor at the first position; based on the capacitance change amount of the TP sensor at the first position and a preset ratio, and obtain the capacitance change threshold of the TP sensor at the first position. Similarly, the electronic device can obtain the capacitance variation of the TP sensor at the second position in response to detecting that the stylus touches the second position of the touch screen; based on the capacitance of the TP sensor at the second position The change amount and the preset ratio are used to obtain the threshold value of the capacitance change amount of the TPsensor at the second position.

According to this, the calculation amount of the electronic device can be reduced.

若至少一个位置的TP sensor的电容变化量阈值中未包含所述第一位置的TPsensor的电容变化量，电子设备可以基于第一位置的TP sensor的电容变化量和预设比例，获取第一位置的TP sensor的电容变化量阈值。If the capacitance change threshold of the TP sensor in at least one position does not include the capacitance change of the TP sensor in the first position, the electronic device may obtain the first position based on the capacitance change of the TP sensor in the first position and a preset ratio.

Wherein, if the holding information indicates that the stylus is being held, the electronic device may determine that the user is holding the stylus, and if the holding information indicates that the stylus is not being held, the electronic device may determine that the user is not holding the stylus.

Referring to FIG. 11A , in FIG. 11A , peaks are used to represent changes in capacitance variation at corresponding positions on the touch screen, and the electronic device can determine the position of the tip of the stylus based on the capacitance variation on the touch screen. In addition, the electronic device can obtain the included angle by using the double-tip projection method in the inclination detection algorithm. Referring to FIG. 11B , in one embodiment, the first electrode and the second electrode in the stylus can be arranged at the tip of the stylus, the first electrode is arranged near the tip of the stylus, and the second electrode is far away from the first electrode. The tip setting for the nib. When the touch sensor receives the first signal from the first electrode of the stylus and the second signal from the second electrode, the capacitance variation at two positions (such as position B and position C) on the touch screen will change, and the electronic device The included angle can be obtained based on the distance between the first electrode and the second electrode, and the distance between two positions on the touch screen. For a more specific dual-tip projection method, reference can be made to relevant descriptions in the prior art. In FIG. 11A , black dots represent positions where the stylus touches the touch screen, and in FIG. 11B black dots represent positions B and C.

图12为已有的电子设备绘制触控笔的笔迹的一种示意图。参照上述图2B的相关描述，触控笔的笔尖中可以设置压力传感器。参照图12，触控笔的笔尖接触电子设备的触摸屏时，压力传感器可以采集笔尖的压感数据，且将该压感数据通过蓝牙发送给电子设备。其中，压感数据可以包括压力值。另外，基于图10中的相关描述，当电子设备与触控笔蓝牙连接成功时，触控笔可以向电子设备发送下行信号，电子设备通过该下行信号可以获取触控笔在触摸屏上的位置，以及触控笔与触摸屏之间的夹角。在一种实施例中，下行信号可以称为触摸(touch panel，TP)信号，下述以TP信号为例进行说明。FIG. 12 is a schematic diagram of an existing electronic device drawing handwriting of a stylus. Referring to the relevant description of FIG. 2B above, a pressure sensor may be provided in the tip of the stylus. Referring to FIG. 12 , when the tip of the stylus touches the touch screen of the electronic device, the pressure sensor can collect the pressure-sensitivity data of the pen tip and send the pressure-sensitivity data to the electronic device via Bluetooth. Wherein, the pressure-sensitive data may include a pressure value. In addition, based on the related description in FIG. 10 , when the electronic device and the stylus are successfully connected via Bluetooth, the stylus can send a downlink signal to the electronic device, and the electronic device can obtain the position of the stylus on the touch screen through the downlink signal. and the angle between the stylus and the touchscreen. In an embodiment, the downlink signal may be referred to as a touch panel (TP) signal, and the TP signal is used as an example for illustration below.

现有技术中，电子设备可以基于触控笔的压感信号，以及触控笔的TP信号，在触摸屏上显示触控笔的笔迹。具体的，因为TP信号会导致电子设备中TP sensor的电容变化量发生变化，且电子设备基于压感信号可以获取压力值，若电子设备检测到TP sensor的电容变化量大于或等于电容变化量阈值，且压力值大于或等于压力阈值，则电子设备可以基于触控笔在触摸屏上的位置，在触摸屏的对应位置显示笔迹。In the prior art, the electronic device can display the handwriting of the stylus on the touch screen based on the pressure-sensitive signal of the stylus and the TP signal of the stylus. Specifically, because the TP signal will cause the capacitance change of the TP sensor in the electronic device to change, and the electronic device can obtain the pressure value based on the pressure-sensitive signal, if the electronic device detects that the capacitance change of the TP sensor is greater than or equal to the capacitance change threshold , and the pressure value is greater than or equal to the pressure threshold, the electronic device can display handwriting at a corresponding position on the touch screen based on the position of the stylus on the touch screen.

如果“压感信号”和“TP信号”中有一个条件不满足(如TP sensor的电容变化量小于电容变化量阈值，或者压力值小于压力阈值)，触控笔无法出水，即电子设备在触摸屏上不显示触控笔的笔迹。目前电子设备依据“压感信号”和“TP信号”显示触控笔的笔迹的方式，响应速度慢，控制精度低。具体原因分析如下：If one of the conditions in the "pressure-sensitive signal" and "TP signal" is not satisfied (such as the capacitance change of the TP sensor is less than the capacitance change threshold, or the pressure value is less than the pressure threshold), the stylus cannot discharge water, that is, the electronic device is on the touch screen. The handwriting of the stylus does not appear on the screen. At present, electronic devices display the handwriting of the stylus according to the "pressure-sensitive signal" and "TP signal", which has a slow response speed and low control precision. The specific reasons are analyzed as follows:

压感信号通过蓝牙传输，蓝牙传输有10-20ms的传输时延。若当触控笔刚刚离开触摸屏时，由于传输时延的原因，触控笔还在向电子设备发送压感信号，同时TP sensor的电容变化量仍大于电容变化量阈值，则电子设备还会继续显示触控笔的笔迹，这样会导致出现漏墨的情况，用户体验差。应理解，漏墨指的是：触控笔离开触摸屏后仍然出水，即电子设备仍显示触控笔的笔迹。The pressure-sensitive signal is transmitted through Bluetooth, and Bluetooth transmission has a transmission delay of 10-20ms. If the stylus is still sending pressure-sensitive signals to the electronic device due to the transmission delay when the stylus just leaves the touch screen, and the capacitance change of the TP sensor is still greater than the capacitance change threshold, the electronic device will continue to Display the handwriting of the stylus, which will lead to ink leakage and poor user experience. It should be understood that ink leakage refers to: the stylus still leaks water after it leaves the touch screen, that is, the electronic device still displays the handwriting of the stylus.

另外，触控笔笔尖的压力传感器可以为弹簧管压力传感器，应变片式压力传感器等。因为压力传感器本身固有的缺陷，容易受到温漂、变形等影响，即使在压力传感器未接触触摸屏时，压力传感器也可以采集到小的压力值，如1g。其中，g表征9.8N/kg。如此，若将压力阈值设置为很小的值，如1g，容易造成误触发。因此目前往往将压力阈值设置为较大的值，如5g、8g。如此，用户采用触控笔倾斜书写或者轻触触摸屏时，因为压力值小于压力阈值，触控笔不出水，电子设备不会显示触控笔的笔迹，导致电子设备的控制精度低。In addition, the pressure sensor at the tip of the stylus may be a spring tube pressure sensor, a strain gauge pressure sensor, or the like. Because of the inherent defects of the pressure sensor itself, it is easily affected by temperature drift, deformation, etc. Even when the pressure sensor is not in contact with the touch screen, the pressure sensor can also collect small pressure values, such as 1g. Wherein, g stands for 9.8N/kg. In this way, if the pressure threshold is set to a small value, such as 1g, it is easy to cause false triggering. Therefore, the pressure threshold is often set to a larger value at present, such as 5g, 8g. In this way, when the user uses the stylus to write obliquely or touch the touch screen lightly, because the pressure value is less than the pressure threshold, the stylus will not emit water, and the electronic device will not display the handwriting of the stylus, resulting in low control accuracy of the electronic device.

基于如上问题，因为现有技术中在触控笔的笔尖设置压力传感器，来自触控笔的压感信号通过蓝牙传输给电子设备会带来时延问题，本申请实施例中可以在电子设备的触摸屏中新增设置传感器，用于检测触控笔是否接触触摸屏，进而避免因为蓝牙传输造成的时延问题。另外，因为电子设备接收来自触控笔的TP信号时，TP sensor的电容变化量会发生改变，因此为了提高电子设备的控制精度，本申请实施例中采用TP sensor的电容变化量判断是否执行绘制笔迹的操作，因为本申请实施例中不将触摸屏采集的压感信号或加速度信号作为电子设备是否执行绘制笔迹的操作的判断条件，而是作为触发电子设备基于TPsensor的电容变化量判断是否执行绘制笔迹的操作的触发条件，因此本申请实施例中可以将压力阈值和三轴加速度的阈值设置为很小的值，可以提高电子设备的控制精度。应理解，三轴加速度可以包括：X轴加速度、Y轴加速度以及Z轴加速度。Based on the above problems, because the pressure sensor is installed on the tip of the stylus in the prior art, the pressure-sensitive signal from the stylus is transmitted to the electronic device through Bluetooth, which will cause delay problems. A new sensor is added to the touch screen to detect whether the stylus touches the touch screen, thereby avoiding the delay caused by Bluetooth transmission. In addition, because when the electronic device receives the TP signal from the stylus, the capacitance change of the TP sensor will change, so in order to improve the control accuracy of the electronic device, the capacitance change of the TP sensor is used in the embodiment of the present application to determine whether to perform drawing. The operation of handwriting, because in the embodiment of the present application, the pressure-sensitive signal or acceleration signal collected by the touch screen is not used as the judgment condition for whether the electronic device executes the operation of drawing handwriting, but as a trigger for the electronic device to judge whether to perform drawing based on the capacitance change of the TPsensor The trigger condition for the operation of the handwriting, so in the embodiment of the present application, the pressure threshold and the threshold of the three-axis acceleration can be set to very small values, which can improve the control accuracy of the electronic device. It should be understood that the three-axis acceleration may include: X-axis acceleration, Y-axis acceleration, and Z-axis acceleration.

据此，本申请实施例中提供一种笔迹绘制方法，可以通过电子设备中新增设置的传感器，判断触控笔是否接触触摸屏(检测有压力值，无需检测一定的压力值如5g)，响应于检测到触控笔接触触摸屏，可以基于TP sensor的电容变化量判断是否执行绘制笔迹的操作。如此，不仅解决了因为蓝牙传输造成的时延问题，还可以在用户采用触控笔倾斜书写或者轻触触摸屏时，电子设备均能够绘制笔迹，电子设备绘制笔迹的响应速度快，控制精度高，可以提高用户体验。Accordingly, the embodiment of the present application provides a handwriting drawing method, which can judge whether the stylus touches the touch screen through the newly added sensor in the electronic device (detection has a pressure value, and does not need to detect a certain pressure value such as 5g), and responds After detecting that the stylus touches the touch screen, it can be judged based on the capacitance change of the TP sensor whether to perform the operation of drawing handwriting. In this way, it not only solves the delay problem caused by Bluetooth transmission, but also allows the electronic device to draw handwriting when the user tilts the stylus or touches the touch screen. The electronic device has a fast response speed and high control accuracy. Can improve user experience.

在介绍本申请实施例提供的笔迹绘制方法之前，先介绍本申请实施例提供的电子设备的结构。参照图13A，在一种实施例中，电子设备可以包括：盖板玻璃(cover glass，CG)、触控功能层、显示屏、中框，以及传感器等。触控功能层可以包括如上实施例所述的触摸传感器，显示屏可以包括但不限于为：液晶显示屏(liquid crystal display，LCD)、发光二极管显示屏(light emitting diode display，LED display)等。中框可以理解为电子设备的框架，可以用于安装电子设备中的各元件，如CPU、卡槽等。在一种实施例中，为了区分电子设备中的新增的传感器和TP sensor，可以将传感器称为第一传感器。Before introducing the handwriting drawing method provided in the embodiment of the present application, the structure of the electronic device provided in the embodiment of the present application will be introduced first.

In an embodiment, in order to distinguish the newly added sensor and the TP sensor in the electronic device, the sensor may be called the first sensor.

传感器用于检测是否存在对象与电子设备的CG接触，对象可以为触控笔、用户的手指、关节等。在一种实施例中，传感器可以为压力传感器，压力传感器用于采集因对象接触CG，造成CG表面形变产生的压感信号。在一种实施例中，传感器可以为加速度传感器，传感器可以采集因对象触碰CG，造成电子设备震动产生的加速度信号。应理解，以压力传感器为例，若压力传感器能够采集到压感信号，则电子设备可以确定存在对象接触电子设备的CG，接触CG可以理解为：接触电子设备的触摸屏。The sensor is used to detect whether there is a CG contact between an object and the electronic device, and the object may be a stylus, a user's finger, a joint, and the like. In one embodiment, the sensor may be a pressure sensor, and the pressure sensor is used to collect pressure-sensitive signals generated by deformation of the CG surface caused by the object contacting the CG. In an embodiment, the sensor may be an acceleration sensor, and the sensor may collect an acceleration signal generated by vibration of the electronic device caused by the object touching the CG. It should be understood that, taking the pressure sensor as an example, if the pressure sensor can collect pressure-sensitive signals, the electronic device can determine that there is an object touching the CG of the electronic device, and contacting the CG can be understood as: touching the touch screen of the electronic device.

参照图13A，传感器可以设置在显示屏上，且设置在显示屏上远离CG的一侧。在一种实施例中，传感器可以粘贴设置在显示屏上，也可以与显示屏卡扣连接，本申请实施例中对传感器的设置方式不做限制。参照图13B，传感器可以设置在中框上，且设置在中框上靠近显示屏的一侧。在一种实施例中，传感器可以粘贴设置在中框上，也可以与中框卡扣连接，本申请实施例中对传感器的设置方式不做限制。Referring to FIG. 13A , the sensor may be disposed on the display screen, and disposed on the side of the display screen away from the CG. In an embodiment, the sensor can be pasted on the display screen, or can be connected with the display screen by buckling. In this embodiment of the present application, there is no limitation on the arrangement method of the sensor. Referring to FIG. 13B , the sensor may be disposed on the middle frame, and disposed on the side of the middle frame close to the display screen. In one embodiment, the sensor can be pasted on the middle frame, or can be connected with the middle frame by buckling. In the embodiment of the present application, there is no limitation on the arrangement of the sensor.

在一种实施例中，为了保证压力传感器可以采集因CG表面的微小形变产生的压感信号，或者保证加速度传感器可以采集因微小震动产生的加速度信号，本申请实施例中可以采用高精度的压力传感器或加速度传感器。或者，可以在显示屏远离CG的一侧设置多个压力传感器，在中框靠近显示屏的一侧设置多个加速度传感器，以提高传感器采集信号的精度。应理解，图13A中以在显示屏上远离CG的一侧设置2个压力传感器进行示例，图13B中以在中框上靠近显示屏的一侧设置2个加速度传感器进行示例。In one embodiment, in order to ensure that the pressure sensor can collect the pressure-sensing signal generated by the small deformation of the CG surface, or to ensure that the acceleration sensor can collect the acceleration signal generated by the small vibration, the embodiment of this application can use high-precision pressure sensors or accelerometers. Alternatively, multiple pressure sensors can be set on the side of the display screen away from the CG, and multiple acceleration sensors can be set on the side of the middle frame close to the display screen, so as to improve the accuracy of the signals collected by the sensors. It should be understood that in FIG. 13A , two pressure sensors are set on the side of the display screen away from the CG as an example, and in FIG. 13B two acceleration sensors are set on the side of the middle frame close to the display screen.

应理解，当传感器为加速度传感器时，加速度传感器不限于设置在图13A和图13B所示的位置，如加速度传感器还可以设置在电子设备的主板上等其他位置。It should be understood that when the sensor is an acceleration sensor, the acceleration sensor is not limited to be disposed at the position shown in FIG. 13A and FIG. 13B , for example, the acceleration sensor may also be disposed at other positions such as the main board of the electronic device.

在图13A和图13B所示的电子设备的基础上，下面结合具体的实施例对本申请实施例提供的笔迹绘制方法进行说明。下面这几个实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例不再赘述。On the basis of the electronic device shown in FIG. 13A and FIG. 13B , the handwriting drawing method provided by the embodiment of the present application will be described below in conjunction with specific embodiments.

Referring to Figure 14, the handwriting drawing method provided by the embodiment of the present application may include:

S1401，响应于检测到触控笔接触电子设备的触摸屏的第一位置，获取第一位置的TP sensor的电容变化量阈值。S1401. In response to detecting a first position where the stylus touches the touch screen of the electronic device, acquire a capacitance change threshold of the TP sensor at the first position.

本申请实施例中，电子设备可以检测触控笔接触电子设备的触摸屏。其中，电子设备可以基于压力传感器采集的压感信号，或加速度传感器采集的加速度信号，检测触控笔接触触摸屏。应理解，压感信号包括压力值，加速度信号包括三轴加速度。In the embodiment of the present application, the electronic device may detect that the stylus touches the touch screen of the electronic device. Wherein, the electronic device may detect that the stylus touches the touch screen based on the pressure-sensitive signal collected by the pressure sensor, or the acceleration signal collected by the acceleration sensor. It should be understood that the pressure-sensing signal includes a pressure value, and the acceleration signal includes triaxial acceleration.

在一种实施例中，若电子设备检测到压力传感器采集的压力值或加速度传感器采集的三轴加速度，则确定触控笔接触触摸屏。In one embodiment, if the electronic device detects the pressure value collected by the pressure sensor or the triaxial acceleration collected by the acceleration sensor, it determines that the stylus touches the touch screen.

在一种实施例中，为了避免外界因素干扰，提高检测准确性，可以设置压力阈值和三轴加速度的阈值。应理解的是，与现有技术相比较，本申请实施例中的压力阈值和三轴加速度的阈值可以设置为较小的值。示例性的，现有技术中压力阈值设置为5-10g，本申请实施例中的压力阈值可以设置为2g，进而电子设备能够实现更高精度的控制。其中，若电子设备检测到压力传感器采集的压力值大于压力阈值，或者加速度传感器采集的三轴加速度大于三轴加速度的阈值，可以确定触控笔接触触摸屏。In an embodiment, in order to avoid interference from external factors and improve detection accuracy, a pressure threshold and a triaxial acceleration threshold may be set. It should be understood that, compared with the prior art, the pressure threshold and the triaxial acceleration threshold in the embodiment of the present application may be set to smaller values. Exemplarily, the pressure threshold is set to 5-10g in the prior art, and the pressure threshold in the embodiment of the present application can be set to 2g, so that the electronic device can achieve higher precision control. Wherein, if the electronic device detects that the pressure value collected by the pressure sensor is greater than the pressure threshold, or the triaxial acceleration collected by the acceleration sensor is greater than the threshold of the triaxial acceleration, it can be determined that the stylus touches the touch screen.

本申请实施例中，电子设备检测到触控笔接触触摸屏时，可以基于来自触控笔的TP信号，检测触控笔接触触摸屏上的位置，本申请实施例以触控笔接触电子设备的触摸屏的位置为第一位置进行说明，电子设备检测触控笔接触触摸屏的位置可以参照上述图11A中的相关描述。In the embodiment of the present application, when the electronic device detects that the stylus touches the touch screen, it can detect the position on the touch screen where the stylus touches the touch screen based on the TP signal from the stylus. In the embodiment of the present application, the stylus touches the touch screen of the electronic device The position of the stylus is the first position for description, and the position where the electronic device detects that the stylus touches the touch screen can refer to the related description in FIG. 11A above.

应理解，TP sensor的电容变化量阈值可以理解为：触发电子设备执行绘制笔迹的操作的参数。第一位置的TP sensor的电容变化量阈值可以理解为：触发电子设备在第一位置执行绘制笔迹的操作的参数。应理解，下述可以将TP sensor的电容变化量阈值简称为阈值。It should be understood that the capacitance change threshold of the TP sensor can be understood as: a parameter that triggers the electronic device to perform the operation of drawing handwriting. The capacitance change threshold of the TP sensor at the first position can be understood as: a parameter that triggers the electronic device to perform an operation of drawing handwriting at the first position. It should be understood that the capacitance change threshold of the TP sensor may be referred to as the threshold for short below.

在一种实施例中，第一位置的TP sensor的电容变化量阈值与“触控笔接触触摸屏的第一位置时的TP sensor的电容变化量”相关。在一种实施例中，第一位置的TP sensor的电容变化量阈值A1可以由如下公式一获取：In one embodiment, the capacitance change threshold of the TP sensor at the first position is related to "the capacitance change of the TP sensor when the stylus touches the first position of the touch screen". In one embodiment, the capacitance change threshold A1 of the TP sensor at the first position can be obtained by the following formula 1:

A1＝c×A   公式一A1＝c×A Formula 1

A表征触控笔接触触摸屏的第一位置时的TP sensor的电容变化量，c为定值。其中，c为大于0小于1的值。在一种实施例中，c可以称为预设比例，即表征第一位置的TPsensor的电容变化量阈值与第一位置的TP sensor的电容变化量的比值。A represents the capacitance change of the TP sensor when the stylus touches the first position of the touch screen, and c is a constant value. Wherein, c is a value greater than 0 and less than 1. In an embodiment, c may be referred to as a preset ratio, that is, a ratio representing the capacitance change threshold of the TP sensor at the first position and the capacitance change of the TP sensor at the first position.

示例性的，如触控笔接触触摸屏的第一位置时的TP sensor的电容变化量为4500，c为0.5，则第一位置的TP sensor的电容变化量阈值A1为2250。Exemplarily, if the capacitance change of the TP sensor when the stylus touches the first position of the touch screen is 4500, and c is 0.5, then the capacitance change threshold A1 of the TP sensor at the first position is 2250.

电子设备的TP sensor可以看做电极阵列，电极阵列由多个电极构成。因为电极制造原因，TP sensor中的电极不一致，进而造成TP sensor的TP信号不一致。TP信号不一致可以理解为：当触控笔接触触摸屏的不同位置时，TP sensor的电容变化量不同。因此，本申请实施例中，电子设备可以基于触控笔接触触摸屏的第一位置时的TP sensor的电容变化量，获取第一位置时的TP sensor的电容变化量阈值。应理解，触摸屏上的位置不同，对应不同的TP sensor的电容变化量阈值。The TP sensor of electronic equipment can be regarded as an electrode array, and the electrode array is composed of multiple electrodes. Due to electrode manufacturing reasons, the electrodes in the TP sensor are inconsistent, which in turn causes the TP signal of the TP sensor to be inconsistent. The inconsistent TP signal can be understood as: when the stylus touches different positions of the touch screen, the capacitance of the TP sensor changes differently. Therefore, in the embodiment of the present application, the electronic device may acquire the capacitance change threshold of the TP sensor at the first position based on the capacitance change of the TP sensor when the stylus touches the first position of the touch screen. It should be understood that different positions on the touch screen correspond to different capacitance change thresholds of the TP sensor.

在一种实施例中，电子设备获取第一位置的TP sensor的电容变化量阈值的方式可以为：电子设备检测到触控笔接触第一位置，可以基于触控笔接触触摸屏的第一位置时的TP sensor的电容变化量以及如上公式一，得到该第一位置的TP sensor的电容变化量阈值。In one embodiment, the manner in which the electronic device obtains the capacitance change threshold of the TP sensor at the first position may be as follows: the electronic device detects that the stylus touches the first position, which may be based on when the stylus touches the first position of the touch screen The capacitance variation of the TP sensor and the above formula 1 are used to obtain the capacitance variation threshold of the TP sensor at the first position.

其中，电子设备在获取第一位置的TP sensor的电容变化量阈值后，可以存储第一位置的TP sensor的电容变化量阈值。换句话说，电子设备中存储有映射关系，该映射关系用于表征触摸屏的各位置的TP sensor的电容变化量阈值。Wherein, after the electronic device obtains the capacitance change threshold of the TP sensor at the first position, it may store the capacitance change threshold of the TP sensor at the first position. In other words, a mapping relationship is stored in the electronic device, and the mapping relationship is used to characterize the capacitance change threshold of the TP sensor at each position of the touch screen.

在一种实施例中，电子设备检测到控笔接触电子设备的触摸屏的第一位置时，可以在映射关系中查询是否存储有第一位置的TP sensor的电容变化量阈值。若存在，则将映射关系中第一位置对应的TP sensor的电容变化量阈值，作为第一位置的TP sensor的电容变化量阈值。若不存在，则可以基于触控笔接触触摸屏的第一位置时的TP sensor的电容变化量，以及上述公式一获取第一位置的TP sensor的电容变化量阈值。In one embodiment, when the electronic device detects that the pen touches the first position of the touch screen of the electronic device, it may inquire whether the capacitance change threshold of the TP sensor at the first position is stored in the mapping relationship. If it exists, the capacitance change threshold of the TP sensor corresponding to the first position in the mapping relationship is used as the capacitance change threshold of the TP sensor at the first position. If it does not exist, the capacitance change threshold of the TP sensor at the first position can be obtained based on the capacitance change of the TP sensor when the stylus touches the first position of the touch screen, and the above formula 1.

S1402，响应于检测到第一位置的TP sensor的电容变化量大于或等于第一位置的TP sensor的电容变化量阈值，执行绘制笔迹的操作。S1402. In response to detecting that the capacitance change of the TP sensor at the first position is greater than or equal to the capacitance change threshold of the TP sensor at the first position, perform an operation of drawing handwriting.

因为触控笔距离触摸屏的距离越近，TP sensor的电容变化量越大，当用户握持触控笔逐渐靠近触摸屏时，TP sensor的电容变化量逐渐增大。当用户握持触控笔接触触摸屏的第一位置时，因为第一位置的TP sensor的电容变化量大于或等于第一位置的TP sensor的电容变化量阈值，因此电子设备可以在第一位置执行绘制笔迹的操作。当用户握持触控笔远离触摸屏时，若检测到触控笔位于触摸屏的第一位置，且第一位置的TP sensor的电容变化量大于或等于第一位置的TP sensor的电容变化量阈值，电子设备仍可以执行绘制笔迹的操作。其中，电子设备在第一位置执行绘制笔迹的操作，可以理解为：触控笔出水。Because the closer the stylus is to the touch screen, the greater the capacitance change of the TP sensor will be. When the user holds the stylus closer to the touch screen, the capacitance change of the TP sensor will gradually increase. When the user holds the stylus and touches the first position of the touch screen, because the capacitance change of the TP sensor at the first position is greater than or equal to the capacitance change threshold of the TP sensor at the first position, the electronic device can execute at the first position The operation of drawing strokes. When the user holds the stylus away from the touch screen, if it is detected that the stylus is located at the first position of the touch screen, and the capacitance change of the TP sensor at the first position is greater than or equal to the capacitance change threshold of the TP sensor at the first position, Electronic devices can still perform the operation of drawing handwriting. Wherein, the electronic device executes the operation of drawing handwriting at the first position, which can be understood as: the touch pen emits water.

在一种实施例中，上述S1402可以替换为：响应于检测到第一位置的TP sensor的电容变化量与第一位置的TP sensor的电容变化量阈值满足第一预设关系时，执行绘制笔迹的操作。其中，第一预设关系可以为：第一位置的TP sensor的电容变化量大于或等于第一位置的TP sensor的电容变化量阈值，或者第一位置的TP sensor的电容变化量大于第一位置的TP sensor的电容变化量阈值。In one embodiment, the above S1402 can be replaced by: in response to detecting that the capacitance change of the TP sensor at the first position and the capacitance change threshold of the TP sensor at the first position meet the first preset relationship, execute drawing handwriting operation. Wherein, the first preset relationship may be: the capacitance change of the TP sensor at the first position is greater than or equal to the capacitance change threshold of the TP sensor at the first position, or the capacitance change of the TP sensor at the first position is greater than the first position The capacitance change threshold of the TP sensor.

S1403，响应于检测到第一位置的TP sensor的电容变化量小于第一位置的TPsensor的电容变化量阈值，停止执行绘制笔迹的操作。S1403, in response to detecting that the capacitance change of the TP sensor at the first position is less than the capacitance change threshold of the TP sensor at the first position, stop executing the handwriting drawing operation.

触控笔距离触摸屏的距离越远，TP sensor的电容变化量越小，当用户使用完触控笔后，用户握持触控笔逐渐远离触摸屏，TP sensor的电容变化量逐渐减小。其中，当用户握持触控笔远离触摸屏时，若电子设备检测到触控笔位于触摸屏的第一位置，且该第一位置的TP sensor的电容变化量小于第一位置的TP sensor的电容变化量阈值，电子设备可以停止执行绘制笔迹的操作。其中，电子设备停止执行绘制笔迹的操作可以理解为：电子设备在第一位置停止执行绘制笔迹的操作，即触控笔不出水。The farther the distance between the stylus and the touch screen, the smaller the capacitance change of the TP sensor. After the user finishes using the stylus, the user holds the stylus away from the touch screen gradually, and the capacitance change of the TP sensor gradually decreases. Wherein, when the user holds the stylus away from the touch screen, if the electronic device detects that the stylus is located at the first position of the touch screen, and the capacitance change of the TP sensor at the first position is smaller than the capacitance change of the TP sensor at the first position If the volume threshold is exceeded, the electronic device can stop performing the operation of drawing handwriting.
