触摸传感装置以及控制装置
摘要：
本发明提供一种操作检测精度高的触摸传感装置。触摸传感装置(10)具备：电极(12)，其设置在触摸面板(11)的背面；以及控制部(13)，其对根据手指的接近而在电极(12)产生的静电电容的变化进行检测，从静电电容的变化判断有无对触摸面板(11)的触摸。控制部(13)在检测出有触摸状态期间对在电极(12)产生的最大静电电容值进行检测，将比该最大静电电容值小预先设定的预定值的值设定为用于检测无触摸状态的第1关闭判断阈值。
摘要（英）：

Provided is a touch sensor device with high operation and detection precison. The touch sensor device (10) includes an electrode (12), which is located at an inner side of a touch panel (11), and a control unit (13). The control unit (13) detects a change in a capacitance generated at the electrode (12) when a finger approaches the electrode (12) to determine whether or not the touch panel (11) has been touched from the change in the capacitance. The control unit (13) detects a maximum capacitance generated at the electrode (12) during detection of a touched state and set a first OFF determination threshold value, which is used to detect a non-touched state, to a value that is lower than the maximum capacitance by a predetermined value which is set in advance.
