By setting the connection mode and the working mode, the operation of the active pen can be effectively distinguished, and the touch screen is convenient to easily identify signals sent by the active pen.

In addition, it should be noted that the touch screen is provided with a touch screen drive, and the operations related to the touch screen in the above process can be realized by the touch screen drive, that is, the active pen interacts with the touch screen drive of the touch screen to realize corresponding short-distance wireless communication connection. The touch screen driver can be a functional module burned in the touch screen chip, or can be a functional module independent of the touch screen chip.

EXAMPLE III

Referring to fig. 3, a timing diagram of a near field communication connection method according to a third embodiment of the present invention is shown.

The embodiment describes the short-range wireless communication connection method provided by the invention in a specific example form from the interaction angle of the active pen, the touch screen and the device where the touch screen is located.

The near field communication connection method of the embodiment includes the following steps:

step S302: and a pen point of the active pen is close to the touch screen, and a coding signal is sent to the touch screen drive.

In this embodiment, taking the active pen as a bluetooth active pen as an example, the bluetooth active pen integrates a short-range wireless communication function, which is specifically a bluetooth function in this embodiment, but is not limited to this, and the short-range wireless communication function may also be an NFC function, a hotknottot function, or other suitable short-range wireless communication functions.

Specifically, in the embodiment, the bluetooth active pen is an independent device, a pen point of the bluetooth active pen can directly perform signal interaction with other devices such as a touch screen of a notebook computer, and the bluetooth device at the tail end of the bluetooth active pen can be interconnected with the bluetooth of the notebook computer to realize information interaction. In this embodiment, the bluetooth active pen may further automatically connect the bluetooth device on the pen with the notebook computer, and the active pen serves as a sending end of information and is responsible for transmitting the relevant information of the bluetooth device on the pen to the touch screen through the pen point.

A touch screen is a component of an electronic device, such as a notebook computer, which can respond to touch events of various media, such as a hand, a pen, etc., and provide coordinate information for an operating system. The touch screen in this embodiment is integrated with a near field communication function, which is specifically a bluetooth function in this embodiment, but the near field communication function may also be an NFC function or a hotspot function. In one connection, the near field communication functions of the active pen and the touch screen are the same, and if the functions are Bluetooth, the active pen and the touch screen have the same functions. In the scheme of the embodiment, the capability of the touch screen for information interaction with the active pen is effectively utilized, and the touch screen is used as an information receiving end to receive identification information from the active pen, such as an equipment identification code, Bluetooth information of the active pen and the like.

The pen point of the active pen is used for coding through a near field communication technology of transmitting codes through the pen point, and in the embodiment, the active pen sends a coding signal to the touch screen through the technology.

But not limited to, a way of sending a code signal, the short-range wireless communication connection scheme of the embodiment also supports customizing a plurality of gestures in an automatic connection process, so as to enrich the operation experience of the user.

For example, the short-distance wireless communication connection between the active pen and the touch screen is realized by adopting a gesture connection mode. For example, when the active pen draws a designated simple figure on the touch screen, for example, draws a letter "O", the touch screen notifies a service process of a system service layer of the device where the touch screen is located, the active pen performs pairing operation, the service process acquires information of the currently connected bluetooth device and matches the information of the currently connected bluetooth device with the information of the currently connected bluetooth device, and if the information of the currently connected bluetooth device matches the information of the currently connected bluetooth device, the active pen directly displays that the active pen is connected on the desktop. If no matched information is found, the service process informs the active pen of entering a broadcasting mode through the touch screen, then the service process opens a Bluetooth searching function of the system, finds a device which is consistent with the Bluetooth information of the active pen in the searched Bluetooth devices, and then completes the pairing action with the device. If the pairing work is not completed at the set time T1, a connection failure may be displayed at the desktop. In the whole process, only one letter O needs to be drawn on the touch screen by the active pen.

For another example, the close-range wireless communication connection between the active pen and the touch screen can be disconnected by adopting a gesture disconnection mode. For example, if a disconnection is desired, the active pen need only draw another designated simple graphic, such as the letter "C". And after recognizing the graph, the touch screen sends a disconnection command to a service process of system service of the equipment where the touch screen is located, and the service process automatically disconnects and displays the disconnection on a desktop according to the acquired Bluetooth information.

In addition, in the embodiment, a touch screen driver of the touch screen is used, so that the touch screen driver is responsible for the interaction with the service process of the device where the touch screen is located and the pen point, and on one hand, the touch screen driver sends a request to the pen point and receives various information transmitted by the pen point; on the other hand, the Bluetooth information on the pen is transmitted to the service process by interacting with the service process.

Step S304: the touch screen drive receives a code printing signal sent by the active pen, and sends a request message to the active pen to request the pen identification code of the active pen.

When the active pen approaches the touch screen, the touch screen driver learns of the event and sends a request message to the active pen requesting the pen identification code.

Step S306: and after receiving the request message sent by the touch screen drive, the active pen transmits the pen identification code to the touch screen drive.

Step S308: and after receiving the pen identification code, the touch screen drive judges whether the pen identification code is connected with the active pen.

Step S310: and under the condition that the touch screen driver is not connected with the active pen, the touch screen driver informs a service process of the equipment where the touch screen is located and transmits the identification code to the service process.

The service process resides on the device where the touch screen is located, such as a notebook computer, and can monitor various information uploaded by the touch screen drive and complete the pairing or disconnection operation of the Bluetooth.

Step S312: the service process judges whether the relevant information of the active pen is stored or not according to the pen identification code, if so, the stored Bluetooth information is directly used for Bluetooth connection, and if not, the step S314 is executed.

Step S314: the service process sends a request to the touch screen driver to request the bluetooth information of the active pen.

Step S316: the touch screen driver sends a request for bluetooth information to the active pen.

Step S318: after receiving the request, the active pen prepares the Bluetooth information and switches the pen point to a connection mode.

Step S320: the active pen sends the relevant bluetooth information to the touch screen drive.

Step S322: and the touch screen drive carries out information verification on the acquired Bluetooth information, transmits the Bluetooth information to the service process after the verification is passed, and simultaneously sends a stop mark to the active pen.

For example, the data carried in the bluetooth information is checked and judged to check whether the acquired bluetooth information is complete, and the like.

Step S324: and after receiving the Bluetooth information, the service process records the Bluetooth information, and opens the Bluetooth equipment of the equipment where the touch screen is located so as to be in Bluetooth connection with the active pen.

Step S326: the touch screen drive records the connection state.
