Examples are some embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present application without departing from the inventive scope are the scope of the present invention.

And B, there are three cases of B alone. In addition, the character " /,,, in this article, generally means that the contextual object is an "or" relationship.

Secondly, the "first electronic device" appearing in this document is configured with a first capacitive touch screen, and the "second electronic device" is configured with a second capacitive touch screen. The first capacitive touch screen and the second capacitive touch screen may be two screens of the same specification (or different specifications). The first and second electronic devices may be: a mobile phone, or a tablet computer, or an in-vehicle computer, a digital camera, or a game machine, etc., and the electronic device of the first and second electronic devices, the embodiment of the present application No specific restrictions are imposed.

Embodiment 1 This embodiment provides a communication method, as shown in FIG. 1, including:

Step 101: When there is capacitive sensing between the first capacitive touch screen of the first electronic device and the second capacitive touch screen of the second electronic device, the first electronic device establishes near field communication with the second electronic device by capacitive sensing;

Step 102: The first electronic device transmits a to-be-transmitted data to the second electronic device by using near field communication.

In a specific implementation process, a first capacitive touch screen is mounted on the first electronic device. A second capacitive touch screen is mounted on the second electronic device. When the first capacitive touch screen and the second capacitive touch screen are facing and close to each other, a capacitive sensing is generated between the first capacitive touch screen and the second capacitive touch screen, and the embodiment of the present application establishes a near sound based on the capacitive sensing. Field communication. Because the capacitive sensing between the capacitive touch screens of the two electronic devices is used to establish the near field communication to realize the data transmission between the two electronic devices, the prior art is effectively solved by using the NFC chip. Near field communication, so there is a technical problem that the NFC antenna affects the overall layout of the electronic device. The technical effect of near field communication realized by a capacitive touch screen widely deployed in current electronic devices is realized.

Further, as shown in FIG. 1A, step 101 includes:

Step 101A: The first electronic device detects, by using the first capacitive touch screen, whether there is a capacitive sense;

Step 102A: When the first electronic device detects that there is capacitive sensing, the first electronic device sends the request information for establishing the near field communication to the second electronic device by capacitive sensing;

Step 103A: The first electronic device receives the response information from the second electronic device by capacitive sensing, and the second electronic device agrees to establish the response information of the near field communication;

Step 104A: The first electronic device establishes near field communication with the second electronic device based on the response information. In a specific implementation process, when the first capacitive touch screen can face and be close to the second capacitive touch screen, capacitive sensing occurs between the first capacitive touch screen and the second capacitive touch screen. At this time, the first electronic The device can detect the capacitive sensing through the first capacitive touch screen, and send the request information for establishing the near field communication to the second electronic device through the capacitive sensing, and wait for the second electronic device After replying to agree to establish the response information of the near field communication, the first electronic device can establish near field communication with the second electronic device based on the response information. In this embodiment, since the first electronic device needs to establish near field communication with the second electronic device based on the response information replied by the second electronic device, the technical effect of establishing a safe and reliable near field communication based on the capacitive touch screen is realized. .

Further, as shown in FIG. 1B, step 102A includes:

Step 101B: The first electronic device modulates the request information, and obtains a modulation request signal corresponding to the request information.

Step 102B: The first electronic device couples the modulation request signal to the receiving channel of the second capacitive touch screen through the transmitting channel of the first capacitive touch screen to implement sending the request information to the second electronic device.

In the capacitive touch screen based on the “compatibility” touch scheme in the prior art, there are multiple transmission channels and multiple receiving channels for sensing the position and the touch operation of the finger when the user performs the touch operation. In the embodiment of the present application, the modulation request signal is coupled to the receiving channel of the second capacitive touch screen by using the transmitting channel to achieve the purpose of transmitting the request information to the second electronic device. It can be seen that, in the embodiment, when the near field communication based on the capacitive touch screen is implemented, the hardware of the electronic device with the capacitive touch screen in the prior art is not required to be modified, thereby realizing that the hardware structure of the electronic device is not changed. Under the premise, the technical effect of near field communication is realized by a capacitive touch screen widely deployed in electronic devices.

In a specific implementation process, the modulation request signal is composed of signals of different frequencies, thereby transmitting different information. For example: For binary, 120 KHz stands for "0", 180KHz stands for "Γ; for hexadecimal, 80 KHz stands for "0", 100 KHz stands for "1", 120 KHz stands for "2"...360 KHz stands for "E", and 380 KHz stands for "F". Which coding format is used for the modulation request signal, which can be customized according to the operating frequency of different capacitive touch screens, and is not specifically limited in this embodiment.

Further, as shown in FIG. 1C, step 102B includes:

Step 101C: The first electronic device acquires a current transmit power of a transmit channel of the first capacitive touch screen. Step 102C: The first electronic device determines whether the current transmit power is greater than or equal to a preset transmit power, where the preset transmit power is a minimum transmit power capable of coupling the modulation request signal to the receive channel of the second capacitive touch screen;

Step 103C: When the current transmit power is greater than or equal to the preset transmit power, the first electronic device couples the modulation request signal to the receive channel of the second capacitive touch screen through the transmit channel of the first capacitive touch screen;

Step 104C: When the current transmit power is less than the preset transmit power, the first electronic device increases the current transmit power to the preset transmit power, and then couples the modulation request signal to the second capacitive touch screen through the transmit channel of the first capacitive touch screen.
