1 is a schematic diagram of an electronic device 100 in accordance with an embodiment of the present invention. The electronic device 100 includes a keyboard device 110 and a tablet computer 120. The keyboard device 110 includes an input device 111, a processor 112, and a transmitting component 113. The input device 111 includes at least one button (such as the button 101), and the buttons are individually coupled to the processor 112. In addition, the transmitting component 113 is a conductive material having a predetermined area and coupled to the processor 112. The tablet 120 includes a touch screen 121 and a processor 122. The touch screen 121 includes at least one touch electrode (for example, the touch electrode 123), and the touch electrodes are individually coupled to the processor 122.

In some embodiments, the user inputs data through at least one button of the input device 111. The processor 112 performs signal processing on the first signal generated by the at least one button, and further converts the first signal generated by the at least one button into a second signal. The processor 112 further transmits the second signal to the transmitting component 113, and transmits the second signal through the transmitting component 113. Then, the tablet 120 is connected to at least one touch electrode of the touch screen 121. Receive the above second signal. The at least one touch electrode transmits the received second signal to the processor 122. The processor 122 further performs signal processing on the second signal to display an image corresponding to the second signal on the tablet 120.

Specifically, in an embodiment, the signal processing performed by the processor 112 on the first signal includes at least an encoding operation and a modulation operation, so that the first signal is converted into the second signal. The processor 112 performs the above encoding operation on the first signal, so that the first signal is encoded into a bit sequence, and the processor 112 further performs a modulation operation on the bit sequence, so as to be based on at least the above coding operation and modulation. The operation converts the first signal to the second signal. In this embodiment, the processor 112 encodes the first signal into the bit sequence 200 through the above encoding operation, as shown in FIG. The bit sequence 200 is provided with bit segments 201, 202, and the bit segments 201, 202 can individually have the same or different number of contiguous elements. In this embodiment, the contents of the bit segment 201 include the most significant bit of the bit sequence, and the contents of the bit segment 201 are keyboard input identification codes. After converting the first signal to the second signal, the processor 112 transmits the second signal to the transmitting component 113, and transmits the second signal through the transmitting component 113.

The tablet 120 receives the second signal through the at least one touch electrode of the touch screen 121, and the at least one touch electrode transmits the received second signal to the processor 122. The signal processing performed by the processor 122 on the second signal includes at least a demodulation operation and a decoding operation. The above-described demodulation operation is corresponding to the above-described modulation operation, and the above-described decoding operation corresponds to the above-described encoding operation. After the demodulation operation is completed, the processor 122 obtains data corresponding to the second signal, where the data packet corresponding to the second signal is obtained. The above keyboard input identification code is included. The processor 122 performs at least the demodulation and decoding operation on the second signal, and generates an image corresponding to the second signal, and displays the image corresponding to the second signal on the tablet 120.

In some embodiments, the processor 122 may determine whether the signal combination received by the at least one touch electrode includes the second signal based on the keyboard input identification code. For example, the processor 122 performs the above-mentioned demodulation and transformation operation on the signal combination, and then individually determines whether the complex bit sequence of the signal combination has the keyboard input identification code. If one of the bit sequence of the bit sequence of the signal combination has the keyboard input identification code, the bit sequence having the keyboard input identification code is the bit sequence corresponding to the second signal, where In this case, the processor 122 displays only the image of the second signal corresponding to the signal combination on the tablet 120.

For example, in some embodiments, the at least one touch electrode of the tablet 120 receives a signal combination and transmits the signal combination to the processor 122. The signal combination includes a touch signal generated by a touch operation and a keyboard signal sent by a keyboard device 110. After performing the demodulation and transformation operation on the signal combination, the processor 122 determines whether the touch signal of the signal combination and the bit sequence corresponding to the keyboard signal respectively have the keyboard input identification code. The processor 122 determines that the bit sequence corresponding to the keyboard signal of the signal combination has the keyboard input identification code. In this case, the processor 122 ignores the touch signal that does not have the keyboard input identification code, and only has the above-mentioned touch signal. The image corresponding to the keyboard signal of the keyboard input identification code is displayed on the tablet 120. Based on the above operation, it is possible to avoid accidentally touching the touch screen of the tablet 120 when inputting data using the keyboard device 110. 121 may cause false input of input data. That is, when the electronic device inputs data through the keyboard device 110, it is not affected by the false touch event of the touch screen 121.

It should be understood that the bit segment 200 of FIG. 2 is for illustrative purposes and does not impose any limitations on the present invention; for example, in other embodiments, the bit segment 202 can be set to the keyboard input described above. The identification code, and the contents of the bit segments 201, 202 can be different from the second picture. In some embodiments, the above encoding operation uses Manchester coding, but the invention is not limited thereto. In some embodiments, the modulation operation uses Frequency Shift Keying (FSK), Phase Shift Keying (PSK), or Amplitude Shift Keying (ASK). However, the invention is not limited thereto.

FIG. 3 is a side view of an electronic device 100 in accordance with an embodiment of the present invention. In some embodiments, the distance between the transmitting component 113 and the at least one touch electrode of the tablet 120 must be less than a predetermined distance. As shown in FIG. 3, in this embodiment, the transmitting component 113 sends the second signal to the touch electrode 123 of the tablet 120, and the distance between the transmitting component 113 and the touch electrode 123 is a predetermined distance D. In this embodiment, the predetermined distance D is less than 10 mm, thereby ensuring that the signal can be correctly transmitted between the transmitting element 113 and the touch electrode 123, but the invention is not limited thereto.

Figure 4 is a flow diagram of a control method 400 in accordance with an embodiment of the present invention for use in a tablet computer. Control method 400 begins in step 401. In step 401, the tablet receives a signal combination, and the process proceeds to step 402. In step 402, the processor of the tablet obtains the individual signal of the signal combination. The corresponding bit sequence, the flow proceeds to step 403. In step 403, the processor determines that the bit sequence corresponding to the first signal of the signal combination has a keyboard input identification code, and the process proceeds to step 404.
