In the embodiment of the application, to realize the pairing and bluetooth connection processes of electronic devices such as tablet devices and mobile phones and capacitive pens and further realize the operation processes of writing ON a capacitive touch screen of the electronic device by using the capacitive pen, firstly, the user can set the capacitive pen control switch to be in an ON (or ON) state according to the operation path of the [ set application "-" auxiliary function "option" - "capacitive pen" control switch ], so that the electronic device can receive and detect one or more operations executed by the user ON the display screen of the electronic device by using the capacitive pen, and support the capacitive pen as an input device of the electronic device.

In addition, different types of electronic devices or electronic devices with different software system versions may be adapted to one or more fixed types of capacitive pens, and the type of the electronic device, the software system version and the type of the capacitive pen are not limited in the embodiments of the present application, and it is assumed that the type of the electronic device, the software system version and the type of the capacitive pen are mutually adapted, which will not be described in detail in the subsequent embodiments.

As shown in fig. 1, the method for preventing false touch operation provided in the embodiment of the present application may be applied to an electronic device having a capacitive touch screen, where the electronic device may include any one of a smart phone, a tablet computer, a wearable device, a vehicle-mounted device, an augmented reality (augmented reality, AR)/Virtual Reality (VR) device, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a personal digital assistant (personal digital assistant, PDA), and a device capable of pairing with a capacitive pen and using the capacitive pen as an input device. The embodiment of the application does not limit the specific type of the electronic equipment. Specifically, the method may include the steps of:

step S110: when the first signal emitted by the capacitive pen is detected, the signal of the transmitting electrode Tx of the capacitive touch screen is shielded.

Capacitive touch screens can be classified into self-capacitive sensing and mutual-capacitive sensing according to the principle of capacitive sensing. The mutual capacitance sensing provides a measurement of capacitance variation between two electrodes, and includes a transmitting electrode Tx and a receiving electrode Rx, wherein the transmitting electrode Tx is used for transmitting a test signal, and the receiving electrode Rx is used for receiving a sensing signal. When a finger touches the interaction area of Tx and Rx on the panel, the current is split due to the fact that the human body is equivalent to equipment ground, so that the current received by the receiving electrode Rx is reduced, equivalent to the reduction of mutual capacitance, and the touch position of the finger is positioned.

In the prior art, a main board of a capacitance pen is provided with a first emitter and a second emitter, the first emitter is electrically connected with a pen point through a pen point spring needle and is used for emitting a first signal, and the first signal is used for generating strokes on a touch screen. The second emitter is used for emitting a second signal, the second emitter is arranged close to the pen point, and the second signal is used for tilting and thickening strokes.

When the pen point of the capacitive pen is in contact with the surface of the capacitive touch screen, the capacitive touch screen shields the signal of the transmitting electrode Tx of the capacitive touch screen when the capacitive touch screen detects the first signal transmitted by the capacitive pen through the pen point. For example, shielding may be performed by powering down the transmitting electrode Tx.

Step S120: and confirming the position of the contact point between the pen point of the capacitive pen and the surface of the capacitive touch screen according to the first signal emitted by the capacitive pen and detected by the receiving electrode Rx of the capacitive touch screen.

The first signal emitted by the capacitive pen nib is detected through the receiving electrode Rx, and the capacitive pen nib is positioned according to the signal fed back by the receiving electrode Rx, so that the position of the contact point between the capacitive pen nib and the surface of the capacitive touch screen is confirmed.

Because the signal of the transmitting electrode Tx of the capacitive touch screen is shielded, when the hand of a user is in contact with the surface of the touch screen, the current received by the receiving electrode Rx at the contact part is constant, namely the mutual capacitance between the transmitting electrode Tx and the receiving electrode Rx is constant, so that false touch is not caused.

Further, if the user wants to use the capacitive pen to perform writing operation on the display screen of the electronic device, the user can write by the following method:

step S130: entering a preset writing mode. Specifically, the method comprises the following steps:

The user uses the capacitance pen to write, and when the pen body of the capacitance pen detects that the finger of the user performs actions such as clicking/double clicking/multi-clicking/sliding on the pen body, a writing mode entering signal is sent to the electronic equipment, and after the electronic equipment receives the writing mode entering signal, the electronic equipment enters a preset writing mode. It should be noted that each finger action may bind a corresponding writing mode, such as a note mode, a mark mode, a revision mode, a mark mode, etc., i.e., different finger actions may trigger the electronic device to enter different writing modes.

Further, after entering the preset writing mode, different pen types can be selected for writing according to the preference and the requirement of the user, for example, a plurality of different pen types such as pen type, writing brush type, sign pen type, marking pen type, brush pen type and the like can be adopted. Thus, the method further comprises:

step S140: receiving a pen type switching signal sent by the capacitance pen, and switching to a preset pen type; the capacitive pen generates the pen-type switching signal according to a second preset finger action detected by the pen body.

In the same way, after the pen body of the capacitance pen detects that the finger of the user performs actions such as clicking/double clicking/multi-clicking/sliding on the pen body, a pen type switching signal is sent to the electronic equipment, and after the electronic equipment receives the pen type switching signal, the pen type is switched to be in a preset pen type.

It should be appreciated that to avoid functional conflicts, the second preset finger action and the first preset finger action should be different.

Step S150: and acquiring a writing track of the capacitive pen nib on the surface of the capacitive touch screen according to the position of the contact point between the capacitive pen nib and the surface of the capacitive touch screen.

Step S160: and driving the capacitive touch screen to display stroke lines matched with the writing track.

Because the thickness degree, the color and the depth degree of the color of the stroke lines wanted by different users when writing are the same, in order to meet the use requirements of different users, the users can adjust the appearance characteristics of the stroke lines after selecting the colors of the lines by the following modes:

first kind:

The thickness degree of the stroke line can only be adjusted by adopting the adjusting scheme, and the number of the receiving electrodes Rx capable of detecting the second signal is limited due to the limited range of the inclination angle of the capacitance pen, so that the width size adjusting range of the stroke line is smaller when the thickness degree of the stroke line is controlled by adopting the scheme.

Second kind:

and receiving a nib pressure signal sent by the capacitance pen, and adjusting the appearance characteristics of the stroke lines according to the nib pressure signal.

The pressure sensor is arranged on the nib of the capacitance pen, and the pressure between the nib and the display screen is used as an adjusting signal when the capacitance pen is used for writing through the pressure sensor. The thickness degree and/or the color depth degree of the stroke lines are/is set according to the pressure value, for example, the thicker the pressure value is, the thicker the stroke lines are displayed on the display screen are, the darker the color is.

When a user uses the capacitance pen to write on the display screen of the electronic equipment, the thickness of the drawing line and the color depth of the drawing line can be adjusted by adjusting the pressure between the pen point of the capacitance pen and the display screen, so that the user operation is facilitated, and the user experience is improved.

The memory stores one or more programs that, when executed by the processor, cause the electronic device to perform the method of the first aspect.

Based on the same inventive concept, in a third aspect, the embodiment of the application further provides an anti-false touch writing system, which comprises an electronic device and a capacitance pen, wherein the electronic device can support the capacitance pen as an input device of the electronic device. The electronic device has a capacitive touch screen, one or more processors, one or more memories, and a module with a plurality of applications installed. The memory stores one or more programs that, when executed by the processor, cause the electronic device to perform the method of the first aspect.
