step S21, when detecting the type change of the paired active pen, determining the update transmission protocol of the changed active pen;

Through the method, the embodiment of the disclosure can determine the updated transmission protocol of the changed active pen when the type change of the paired active pen is detected, switch the changed transmission protocol of the active pen into the updated transmission protocol, and reconfigure the touch event information based on the updated transmission protocol, so as to support other types of active pens, thereby improving the flexibility and the expandability.

In one example, the active pen may be paired by Radio Frequency Identification (RFID) technology, infrared data association (IrDA) technology, Ultra Wideband (UWB) technology, Bluetooth (BT) technology, and other technologies, and when the pairing is completed, the display panel may detect the model of the active pen (e.g., by unique identification information, version information, or other information of the active pen), and when the active pen changes, the update transmission protocol may be obtained from the storage module or the network.

For example, the display panel may actively acquire and store in the storage module various transmission protocols of the active pen each time a firmware update, a system update, or networking is performed. In one example, a memory module may include a computer-readable storage medium, which may be a tangible device that may hold and store instructions for use by an instruction execution device. The computer readable storage medium may be, for example, but not limited to, an electronic memory device, a magnetic memory device, an optical memory device, an electromagnetic memory device, a semiconductor memory device, or any suitable combination of the foregoing.

Computer-readable storage media as used herein is not to be construed as transitory signals per se, such as radio waves or other freely propagating electromagnetic waves, electromagnetic waves propagating through a waveguide or other transmission medium (e.g., optical pulses through a fiber optic cable), or electrical signals transmitted through electrical wires.

In one example, the display panel may communicate by wired or wireless means to obtain the protocol on the server or external memory. The display panel may have access to a wireless network based on a communication standard, such as WiFi, 2G or 3G, or a combination thereof.

In an example, the user may also update the touch event information as needed, for example, in a case that the active pen is not changed, the user may reconfigure the touch event information as needed, such as increasing a detection instruction, changing an order of the detection instruction, and the like, and the user may configure the touch event information through a configuration interface, which is not limited in the embodiment of the present disclosure.

In one possible implementation, the method may further include:

and when the timing duration reaches the trigger duration corresponding to any one of the moving pen uplink instruction, the active pen downlink instruction and the active pen detection instruction, configuring the touch module of the display panel to work in a self-capacitance mode.

In one example, the display panel may include a touch module, and the touch module may include a touch chip, and when the timing duration is used for triggering the active pen related command, the touch module may be operated in a self-capacitance mode according to an embodiment of the present disclosure, for example, both the sensing electrode and the driving electrode in the touch module may be connected to the sensing unit.

In one example, when performing active pen detection, the active pen may output a signal to a touch module of the display panel, and the display panel may receive a sensing signal to obtain touch related information of the active pen, such as pressure information, frequency information, and the like, and may determine whether active pen contact occurs according to the touch related information.

In one possible implementation, the method may further include:

In one example, when touch detection is performed, a driving signal may be applied to the driving electrode by the driving unit, and a sensing signal is collected from the sensing electrode by the sensing unit, so that when a human body (e.g., a finger) touches the display panel, capacitance between the driving electrode and the sensing electrode changes, and the display panel may detect a position touched by the human body accordingly.

Of course, the above description of the mode configuration of the touch module of the display panel during active pen detection and touch detection is exemplary and should not be considered as a limitation to the embodiments of the present disclosure, and in other embodiments, a person skilled in the art may set the mode according to actual situations.

For example, when the timing duration reaches the trigger duration corresponding to the no-operation instruction, the no-operation is executed, and if the trigger duration of the no-operation instruction is not reached and the trigger duration corresponding to the pen uplink operation instruction is reached, a pen uplink start signal is generated and the pen uplink operation is executed.

In one example, as shown in fig. 4, the pen-up time slot and the execution time slots of other detection instructions are separated by the display time slot, so that the embodiments of the present disclosure can avoid the mutual influence of the execution of the detection instructions, thereby improving the accuracy of touch detection.

The apparatus may be applied to a display panel, as shown in fig. 5, and includes:

In one example, the comparison and parsing unit 2120 may include a comparison circuit, which compares the timing duration with the trigger duration to determine a detection instruction to be executed, and obtains the detection instruction according to the address information to send to the second execution unit 220.

In one example, the second execution unit 220 may include a touch chip, and may execute the detection instruction to implement an active pen, human touch detection, or other operations.
