[0031] Figure 1 Schematic diagram of a keyboard 1 with a writable touchpad according to an embodiment of the present application. Figure 2 Schematic diagram of a keyboard 1 with a writable touchpad according to another embodiment of the present application. As Figure 1 and Figure 2 shown, the keyboard 1 with a writable touchpad includes a capacitive touchpad 11 and a plurality of input keys 13 arranged in a QWERTY layout. The user uses a charged body 15, such as a finger or an active stylus, to input data via the capacitive touchpad 11, and can also input the data by pressing the plurality of input keys 13 arranged in the QWERTY layout, and then transmits the data to a display screen for display through a communication protocol 17. In this embodiment, the communication protocol 17 includes Universal Serial Bus (USB).
[0032] Figure 3 is Figure 1 and Figure 2 shown signal transmission module diagram of the keyboard 1. As Figure 1 , Figure 2 and Figure 3 shown, when the user uses the charged body 15 to input data on the capacitive touchpad 11, a touch signal is generated in response to the action of the charged body 15 on the capacitive touchpad 11 and is transmitted to a touch signal type identification module 21 of the keyboard 1 to identify the type of the touch signal.
[0033] In an embodiment of the present application, the touch signal is generated in response to the change in the capacitance value of the path sensed by the capacitive touchpad 11 when the charged body 15 contacts and continuously moves on the capacitive touchpad 11. Therefore, the touch signal type identification module 21 identifies the type of the touch signal as a finger touch signal type. In this embodiment, the charged body 15 includes a finger. When the finger contacts the capacitive touchpad 11 and continuously moves on the capacitive touchpad 11, the capacitive touchpad 11 senses the change in the capacitance value of the path of the continuous movement of the charged body to generate a touch signal, and the touch signal type identification module 21 identifies the type of the touch signal as a finger touch signal type according to the generation manner of the touch signal. For example: when a finger contacts and continuously moves on the capacitive touchpad 11, the capacitive touchpad 11 senses the position coordinates of the change in the capacitance value of the path of the continuous movement to generate the touch signal.
[0034] In an embodiment of the present application, the capacitive touchpad 11 senses the wireless signal source of the charged body 15 to generate a touch signal. Therefore, the touch signal type identification module 21 identifies the type of the touch signal as a pen touch signal type according to the touch signal generation method. In this embodiment, the charged body 15 includes an active stylus. That is, when the wireless signal source of an active stylus is sensed by the capacitive touchpad 11, a touch signal is generated, and the touch signal type identification module 21 identifies the type of the touch signal as a pen touch signal type according to the touch signal generation method. In addition, when the active stylus continuously moves on the capacitive touchpad 11, the capacitive touchpad 11 senses the continuous movement path of the pen touch signal to calculate the position coordinates.
[0035] In an embodiment, the wireless signal source includes a wireless signal source compliant with the Microsoft Pen Protocol (MPP). In an embodiment, the wireless signal source includes a wireless signal source compliant with the Universal Stylus Initiative (USI).
[0036] The keyboard 1 further includes a signal output module 23, and the signal output module 23 is configured to output a signal via the communication protocol 17 according to the type.
[0037] Figure 4 It is a schematic diagram of a keyboard 1' with a writable touchpad according to an embodiment of the present application. In this embodiment, the keyboard 1' with a writable touchpad is similar to Figure 1 the shown keyboard 1 with a writable touchpad, but the communication protocol 17 includes the Institute of Electrical and Electronics Engineers (IEEE) 2.4 GHz. In another embodiment, the communication protocol 17 includes Bluetooth.
