具体实施方式Detailed ways

根据本发明，一电容式触控板的结构及利用该结构的省电机制如图1所示，软性电容式触控板10包括在一软板17上加工导体使其具有绝缘层11、导体12、绝缘层13、导体14、绝缘层15及导体16相互交错组成的三明治结构，其中，导体12及14为软性电容式触控板10的感应器，导体16为接地层且较佳者其包括一网状图样，电路板20的表面具有一层导体22，一般而言，导体22包括铜箔，弹性绝缘体30填充于软性电容式触控板10与电路板20之间，以及控制电路40具有一输入/输出端口(I/O port)42与导体22连接，利用习知的端口变化(port changed)机制达到唤醒触控板的功能。当不使用电容式触控板时，其所有电路被关闭，只有端口变化侦测电路仍在运作，因此消耗功率极低。在此省电模式下，软性电容式触控板10与电路板20之间为浮接。欲使用电容式触控板时，一旦手指按压软性电容式触控板10，导体16便与导体22接触，产生电压变化信号给控制电路40的输入/输出端口42，例如电压信号由高准位变为低准位，因而引发一唤醒机制，促使电容式触控板由省电模式回复至正常操作模式。利用此省电机制可使电容式触控板的消耗功率降至最低，而且唤醒的反应时间短，不需重新校准触控板。控制电路40中使用的端口变化侦测电路为现有的微控制器常用的技术，因此不增加成本。较佳者，控制电路40就包含在触控板的微控制器中，而且是安装在电路板20上，因此完全不增加硬件成本。According to the present invention, the structure of a capacitive touch panel and the power saving mechanism utilizing the structure are shown in FIG. Conductor 12, insulating layer 13, conductor 14, insulating layer 15 and conductor 16 are interlaced sandwich structures, wherein conductors 12 and 14 are sensors of the flexible capacitive touch panel 10, and conductor 16 is a grounding layer and is preferably Or it includes a mesh pattern, the surface of the circuit board 20 has a layer of conductor 22, generally speaking, the conductor 22 includes copper foil, the elastic insulator 30 is filled between the flexible capacitive touch panel 10 and the circuit board 20, and The control circuit 40 has an input/output port (I/O port) 42 connected to the conductor 22, and utilizes a known port changed (port changed) mechanism to achieve the function of waking up the touch panel. When the capacitive touch panel is not used, all its circuits are turned off, and only the port change detection circuit is still operating, so the power consumption is extremely low. In this power-saving mode, the flexible capacitive touch panel 10 and the circuit board 20 are floating. When the capacitive touch panel is to be used, once the finger presses the soft capacitive touch panel 10, the conductor 16 will contact the conductor 22 to generate a voltage change signal to the input/output port 42 of the control circuit 40, for example, the voltage signal is sent by Micro Motion bit goes low, thereby initiating a wake-up mechanism that returns the capacitive touchpad from power-saving mode to normal operation. Utilizing this power-saving mechanism can minimize the power consumption of the capacitive touch panel, and the wake-up response time is short, and there is no need to recalibrate the touch panel. The port change detection circuit used in the control circuit 40 is a commonly used technology in existing microcontrollers, so it does not increase the cost. Preferably, the control circuit 40 is included in the microcontroller of the touch panel, and is mounted on the circuit board 20 , so the hardware cost is not increased at all.
