在一个可选的实施例中，如图5所示，所述选项区还包括选项电路，所述选项电路包括多个分压电阻R1，根据所述选择开关选择的选项使用对应的分压电阻以输出所述选项信号。In an optional embodiment, as shown in FIG. 5 , the option area further includes an option circuit, the option circuit includes a plurality of voltage dividing resistors R1, and the corresponding voltage dividing resistors are used according to the option selected by the selection switch to output the option signal.
以颜色选项区191为例进行说明，所述选项电路包括多个串联在电源VCC和公共端GND之间的分压电阻R1以区分不同选项档位，每个分压电阻对应分压开关，通过选择开关选择的选项闭合对应的分压开关以输出对应的颜色选项信号，例如V1_1至V1_5中的一个。具体的，所述电源VCC为12V，R1为2KΩ，则V1_1至V1_5分别为2V/4V/6V/8V/10V。响应于选择的绿色输出颜色选项信号V1_1为6V模拟信号，并传输至模数转换器转换为数字选项信号；所述模数转换器的比较电压设置为16V，则利用4位数字比较即可实现模数转换功能；将数字选项信号传输至处理器，所述处理器预设置5个低频的信号段，例如为120Hz/240Hz/360Hz/480Hz/600Hz，分别对应颜色选项区的5种颜色选项红色、蓝色、绿色、黄色和黑色，例如选择绿色则生成的信号段为360Hz。Taking the color option area 191 as an example for illustration, the option circuit includes a plurality of voltage dividing resistors R1 connected in series between the power supply VCC and the common terminal GND to distinguish different option gears. Each voltage dividing resistor corresponds to a voltage dividing switch. The option selected by the selection switch closes the corresponding voltage divider switch to output the corresponding color option signal, for example, one of V1_1 to V1_5. Specifically, the power supply VCC is 12V, R1 is 2KΩ, then V1_1 to V1_5 are 2V/4V/6V/8V/10V respectively. In response to the selected green output color option signal V1_1 is a 6V analog signal, and is transmitted to the analog-to-digital converter to be converted into a digital option signal; the comparison voltage of the analog-to-digital converter is set to 16V, which can be realized by using 4-bit digital comparison Analog-to-digital conversion function; the digital option signal is transmitted to the processor, and the processor presets 5 low-frequency signal segments, such as 120Hz/240Hz/360Hz/480Hz/600Hz, corresponding to the 5 color options in the color option area red , blue, green, yellow and black, for example, if green is selected, the generated signal segment is 360Hz.
同理，响应于线宽选项区192和色度选项区193中各选项开关选择的选项分别输出线宽选项信号V2和色度选项信号V3并传输至模数转换器转换为数字选项信号，所述线宽选项区192和色度选项区193可以重复利用上述颜色选项区191的5个低频信号段，也可以由处理器生成与其对应的其他信号段。Similarly, in response to the options selected by the option switches in the line width option area 192 and the chroma option area 193, the line width option signal V2 and the chroma option signal V3 are respectively output and transmitted to the analog-to-digital converter for conversion into digital option signals, so The line width option area 192 and the chroma option area 193 may reuse the five low-frequency signal segments in the color option area 191 , or generate other corresponding signal segments by the processor.
最后，所述处理器按照预定义格式通过所述发射电极发送多个数字选项信号，即按照预定义格式通过发射电极发送对应的信号段。例如处理器以串行方式依次发射颜色数字选项信号、线宽数字选项信号和色度数字选项信号对应信号段的低频信号，从而使得所述触控笔进行触控操作的触控面板根据接收到的多个数字选项信号显示各数字选项信号对应的显示效果，例如在本实施例中，所述触控面板在触控笔触控的位置处显示第四线宽、第二色度的绿色线条。Finally, the processor sends a plurality of digital option signals through the transmitting electrode according to a predefined format, that is, sends corresponding signal segments through the transmitting electrode according to a predefined format. For example, the processor sequentially transmits the low-frequency signal of the signal segment corresponding to the color digital option signal, the line width digital option signal, and the chroma digital option signal in a serial manner, so that the touch panel for touch operation of the stylus can receive The multiple digital option signals display the display effect corresponding to each digital option signal. For example, in this embodiment, the touch panel displays a green line with a fourth line width and a second chromaticity at the position touched by the stylus.
