Description

Pairing method for actively switching communication protocol and stylus for actively switching communication protocol

A pairing method and a touch pen, particularly a pairing method for actively switching communication protocols and a touch pen for actively switching communication protocols.

In the modern era of advanced technology, consumers can buy touch components of various brands in the market. The touch components usually include a stylus and a touchpad. The touchpad is located between the stylus and the touchpad. Communication is performed through a specific communication protocol, so that the stylus can exchange data with the touchpad, so that the touchpad can recognize the data sent by the stylus, and then perform advanced touch operations, such as The touch panel can receive the tip pressure information transmitted by the touch pen, and confirm the pressure of the tip of the touch pen, so as to change the thickness of the strokes displayed by the touch panel and produce a brush-like effect.

However, touch components of different brands use respective communication protocols for communication, so that the stylus and the touchpad of different brands cannot communicate. For example, a touchpad of brand A that uses a type A communication protocol cannot communicate with a stylus of brand B that uses a type B communication protocol. In short, due to different communication protocols, even if the touchpad of brand A receives the wireless signal from the stylus of brand B, the touchpad of brand A cannot recognize the wireless signal sent by the stylus of brand B. Also, advanced touch operations cannot be performed.

That is to say, the current stylus can only wirelessly communicate with the touchpads of the same brand, and cannot be used for touchpads of different brands, and the generality is poor. Therefore, the touch components of the prior art must be further improved.

The main purpose of the present invention is to provide a pairing method for actively switching communication protocols and a stylus for actively switching communication protocols, so that the stylus can be paired with a plurality of touchpads using different touch modes, so as to improve the touch performance.

In addition, the stylus that actively switches the communication protocol includes a stylus processing unit and a stylus antenna unit. The touch pen processing unit is electrically connected to the touch pen antenna unit. The stylus processing unit is used for judging whether the pairing mode activation condition is satisfied. When the pairing mode activation condition is satisfied, the stylus processing unit executes the pairing mode to generate the pairing trigger signal, and sends the pairing trigger signal to the touch panel through the stylus antenna unit.

When the stylus processing unit receives the pairing information sent by the touchpad through the stylus antenna unit, the stylus processing unit confirms the communication protocol used by the touchpad according to the pairing information, and ends The pairing mode.

The stylus processing unit further executes the touch mode, and the stylus processing unit generates the touch signal according to the confirmed communication protocol used by the touch panel, and sends the touch signal through the stylus antenna unit control signal to the touchpad.

The present invention uses the touch pen to actively determine the communication protocol used by the touch panel in the pairing mode, and after completing the pairing mode, the touch pen can generate and send a touch signal to the communication protocol confirmed by the touch pen. The trackpad, which enables the stylus to communicate with the trackpad. That is to say, even if the stylus has not confirmed the communication protocol of the touchpad at first and cannot communicate with the touchpad, the stylus can confirm the communication protocol of the touchpad through the pairing method, thereby Communicate with this touchpad. In this way, the stylus can be paired and communicated with touchpads using different communication protocols, thereby improving the versatility of the stylus, and changing the workplace where the stylus and the touchpad are required. be more efficient.

The stylus processing unit 11 further executes the touch mode, and the stylus processing unit 11 generates the touch signal according to the confirmed communication protocol used by the touch panel 20, and transmits the touch signal through the stylus antenna unit 10 sends the touch signal to the touch panel 20 .

In one of the preferred embodiments, when the stylus 10 is powered on and activated, the stylus determines that the pairing mode activation condition is satisfied. For example, when the user replaces the battery of the stylus 10 to power on the stylus 10, the stylus 10 determines that the pairing mode activation condition is satisfied.

In another preferred embodiment, the stylus that actively switches the communication protocol further includes a pairing button 13 , and the pairing button 13 is electrically connected to the stylus processing unit 11 . The stylus processing unit 11 determines whether the pairing button 13 is activated. When the pairing button 13 is activated, the stylus processing unit 11 determines that the pairing mode activation condition is satisfied. For example, when the user presses the pairing button 13, the pairing button 13 is activated, and the stylus 10 satisfies the pairing mode activation condition.

In another preferred embodiment, the pairing button 13 of the stylus that actively switches the communication protocol is disposed on the tail of the stylus 10, and the tip of the stylus 10 is further provided with a pressure sensor, It is used for sensing the pressure of the tip of the stylus 10 to generate a pressure sensing signal, and the pressure sensor is electrically connected to the stylus processing unit 11 to provide the pressure sensing signal to the stylus processing unit 11 . When the stylus processing unit 11 determines that the pairing button 13 is activated and the pressure value corresponding to the pressure sensing signal is greater than an activation pressure value, the stylus processing unit 11 determines that the pairing mode activation condition is satisfied. For example, when the user presses the pairing button 13 and simultaneously presses the tip of the stylus 10 against the touchpad 20 with a certain force, the pairing button 13 is activated and the pressure sensing signal corresponds to If the pressure value is greater than the activation pressure value, the stylus 10 satisfies the activation condition of the pairing mode.

For example, when the user presses the pairing button 13 disposed on the stylus 10, the pairing button 13 is activated, and the stylus 10 determines that the pairing mode activation condition is satisfied. Further, in order to avoid accidentally touching the pairing button 13 and satisfying the pairing mode activation condition, the stylus 10 can further determine whether the pairing button 13 is continuously activated for more than a preset time, and when the pairing button 13 is continuously activated When the activation exceeds the preset time, the touch pen 10 determines that the trigger condition is satisfied. For example, when the user keeps pressing the trigger switch 13 for more than three seconds, the stylus 10 determines that the trigger condition is satisfied, so as to execute the pairing mode, and generate and send the pairing trigger signal to the touch panel 20 .

Further, the touch pen that actively switches the communication protocol further includes an indicator light 14 . The indicator light 14 is electrically connected to the stylus processing unit 11 . When the stylus processing unit 11 executes the pairing mode, the stylus processing unit 11 further generates an indicator light activation signal to activate the indicator light 14 .
