S110: the touch adapter plate receives a first touch signal which is generated when a touch sensor in the touch equipment senses touch operation of a touch object and meets first format information.
The touch object can be an active pen, a passive pen or a finger of an operator; the first touch signal is an induction signal generated by the touch sensor when an operator performs touch operation on the touch equipment through the touch object.
S120: the touch adapter board converts a first touch signal meeting the first format information into a second touch signal meeting the second format information, and sends the second touch signal to the active pen controller, so that the active pen controller generates corresponding touch information according to the second touch signal and sends the touch information to the touch equipment.
It should be noted that the first touch signal and the second touch signal are sensing signals (Rx signals), and the active pen controller may determine, by receiving the Rx signals, capacitance change conditions on the touch sensor during the active pen touch process according to the received Rx signals, so as to determine coordinates of touch points, that is, positions of the touch points.
In the embodiment of the present invention, the format information of the touch signal that can be recognized by the touch sensor is the first format information, the format information of the touch signal that can be recognized by the active pen controller is the second format information, and the touch adapter board can convert the sensing signal returned by the touch sensor into the sensing signal that can be recognized by the active pen controller and send the sensing signal to the active pen controller.
The touch sensor may be a touch sensor in an existing touch device. The touch adapter plate and the active pen controller can be devices independent of the existing touch devices and active pens, can be integrated devices, and can also be independent of the touch adapter plate, the active pen controller is integrated in the active pen, the touch adapter plate and the active pen controller are connected and communicated in a wireless mode, and the like.

Fig. 2 is a flowchart illustrating a method for supporting an active pen according to another embodiment of the present invention. The method may be performed by a computer device (e.g., a touch adapter pad). As shown in fig. 2, the method includes the following.
S210: and the touch adapter plate receives a third touch signal which is sent by the active pen controller and meets the second format information.
S220: the touch adapter board converts the third touch signal meeting the second format information into a fourth touch signal meeting the first format information, and sends the fourth touch signal to the touch sensor.

In one embodiment of the present invention, the method of supporting an active pen further comprises: the touch adapter plate is connected with the active pen controller and connected with the touch sensor.
For example, the touch adapter board and the active pen controller are integrated into a USB device independent of the existing touch device. The touch adapter board can be connected with the active pen controller through the flexible circuit board FPC. In addition, the touch adapter plate can be connected with an FPC of a touch sensor in the touch equipment through a USB interface.
In an embodiment of the present invention, the first format information includes first pin information, and the second format information includes second pin information.
For example, after the touch adapter board is connected to the touch sensor through the FPC, the touch adapter board can detect and identify FPC pin information (i.e., first pin information) of the touch sensor, for example, 128 bits; the touch adapter board may sequentially connect the recognized first pin information according to the pin information (i.e., the second pin information) that can be recognized by the active pen, i.e., perform FPC pin information conversion, e.g., converting 128 bits into 256 bits. Therefore, when the touch adapter board receives the 256-bit touch signal sent by the active pen controller, the 256-bit touch signal can be converted into a 128-bit touch signal which can be identified by the touch sensor; in addition, when the touch adapter board receives a 128-bit touch signal returned by the touch sensor, the 128-bit touch signal can be converted into a 256-bit touch signal which can be recognized by the active pen controller.
It should be understood that the 128 bits and 256 bits are only exemplary descriptions, and the format information may include information such as ground information and power supply signal in addition to the pin information, and the content of the format information is not particularly limited by the present invention.
In an embodiment of the present invention, before the touch adapter board receives a third touch signal satisfying the second format information sent by the active pen controller, the method for supporting the active pen further includes: the method comprises the steps that a touch adapter plate identifies pin information of a touch sensor to obtain first format information, and the first format information is stored; after the touch adapter board converts the third touch signal meeting the second format information into the fourth touch signal meeting the first format information, the method for supporting the active pen further comprises the following steps: the format of the fourth touch signal is collated with the stored first format information, wherein the sending of the fourth touch signal to the touch sensor includes: and when the calibration result is correct, the touch adapter plate sends a fourth touch signal to the touch sensor.
For example, the touch patch panel may save the identified 128-bit pin information to a register. When the touch adapter board converts the 256-bit touch signal from the active pen controller into a 128-bit touch signal, the converted 128-bit touch signal is checked with 128-bit pin information stored in a register to determine whether the converted 128-bit touch signal is correct, and when the conversion is correct, the converted information is sent to the touch sensor; and when the conversion is wrong, the format conversion is carried out again until the correction result is correct. By storing the identified format information, the conversion result can be corrected after the format conversion is carried out on the touch adapter plate, so that the conversion accuracy is improved.
Fig. 3 is a flowchart illustrating a method for supporting an active pen according to another embodiment of the present invention. The method may be performed by a computer device (e.g., a system on a chip). As shown in fig. 3, the method includes the following.
S310: the system chip in the touch device receives touch information sent by an active pen controller outside the touch device, wherein the touch information is generated by the active pen controller according to a second touch signal output by a touch adapter plate, and the second touch signal is obtained by converting the touch adapter plate according to a first touch signal generated by a touch sensor of the touch device when the touch sensor senses touch operation of a touch object.

For example, the touch information may be touch coordinate information and a pressure signal, so that the system chip generates a touch instruction according to the touch coordinate information and the pressure signal, and further generates a response to a touch operation; the touch information may also be a touch instruction generated by the active pen controller according to the touch coordinate information and the pressure signal, so that the system chip generates a response to the touch operation according to the touch instruction.

It should be understood that the above description is only exemplary, and the present invention is not limited in particular to the communication manner between the system chip and the active pen controller.
It should be noted that the conventional touch device can support touch operations of a finger and a passive stylus, but cannot support an active stylus mainly because the original components cannot recognize information (such as a pressure-sensitive signal) output by the active stylus. In view of this, in the embodiment of the present application, the system chip may terminate the connection between the system chip in the existing touch device and the touch controller by receiving connection request information sent by an active pen controller outside the touch device, and terminate the connection between the touch controller and the touch sensor, so as to establish the connection between the system chip and the external active pen controller, so that the existing touch device can support the active pen. That is to say, in the embodiment of the present application, the active pen controller replaces an original touch controller in the touch device, and the active pen controller can not only receive the sensing signal generated by the touch sensor, but also receive information such as a pressure sensing signal output by the active pen, and send the information to the system chip, so that the touch operation of the active pen can be recognized and responded on the premise of not changing the original internal structure of the touch device, and therefore, the embodiment of the present application can be generally applied to any existing touch device.
It should be understood that the communication among the system chip, the touch sensor, and the touch controller in the existing touch device may also be interrupted by shielding, and the connection termination manner among the system chip, the touch sensor, and the touch controller in the existing touch device is not particularly limited by the present invention.

In an embodiment of the present invention, the method for supporting an active pen further includes: the active pen controller receives a pressure intensity signal sent by an active pen, wherein the active pen controller generates touch information according to a second touch signal, and the method comprises the following steps: and the active pen controller generates touch information containing the stroke thickness and the pen point track according to the pressure intensity signal and the second touch signal.
Particularly, the active pen comprises a pressure sensor, and the weight of the stroke, namely the pressure intensity, can be measured. The active pen controller can receive the pressure intensity signal sent by the active pen.
In addition, the active pen controller receives a touch signal (i.e., the second touch signal) including a position of the touch point through the touch adapter plate, and the active pen controller may obtain position information of the touch point according to the touch signal. In addition, the active pen controller can subdivide the touch signal, for example, divide 1 touch signal into 1024 touch signals on average, and then generate a touch instruction containing the stroke thickness according to the pressure intensity. Specifically, the greater the pressure intensity is, the more the number of touch signals is, and the thicker the stroke is; the smaller the pressure intensity is, the fewer the number of touch signals is, and the thinner the stroke is. For example, a thick stroke corresponds to 900 parts and a thin stroke corresponds to 200 parts.
The active pen controller can generate touch information containing pen point tracks (namely touch point positions) and stroke thicknesses by receiving pressure intensity signals sent by the active pen, so that the system chip can control the display screen to present the aesthetic feeling of the stroke thicknesses according to the strength of a user, and the user experience is improved.
