摘要:
The invention provides a touch sensor in which the numbers of channels and wires are decreased simultaneously and a simultaneous touch operation of a plurality of touch keys is realized. A keyboard includes 36 pieces of touch keys disposed in 6 rows and 6 columns, drive lines, and sensor lines on an insulation substrate. The touch key includes a center electrode disposed on the insulation substrate and an annular electrode disposed surrounding this center electrode. A sensor circuit includes a selection circuit and an electric charge amplifier. The electric charge amplifier detects the amount of change of a capacitance of an electrostatic capacitor formed between the center electrode and the annular electrode of the touch key connected to one sensor line selected by the selection circuit.
摘要(中):
本发明提供了一种触摸传感器,其中通道和电线的数量同时减小,并且实现了多个触摸键的同时触摸操作。 键盘包括设置在绝缘基板上的6行6列,驱动线和传感器线中的36个触摸键。 触摸键包括设置在绝缘基板上的中心电极和围绕该中心电极设置的环形电极。 传感器电路包括选择电路和电荷放大器。 电荷放大器检测形成在连接到由选择电路选择的一个传感器线的触摸键的中心电极和环形电极之间形成的静电电容器的电容的变化量。
