[0093] The third electrode 120 and the first electrode 122 at one end of each first sensing element 124 can be electrically connected to the control unit 60 of the electrostatic sensor 300 through wires, so that the control unit 60 can control the module through its circuit 62 applies voltage to each first sensing element 124 respectively, and measures the resistance of each first sensing element 124 through its resistance testing module 64 . Like the electrostatic sensor 200 of the second embodiment, the electrostatic sensor 300 of the third embodiment can sense the position of the electrostatically charged object above its substrate 14 in the second direction Y, and use it for control of electronic devices. In the third embodiment, a plurality of first electrodes 122 in the second embodiment are replaced by one third electrode 120, and the same functions as those in the second embodiment are realized, and the structure is simplified.

[0094] It can be understood that the el...

Abstract

An electrostatic sensing method is provided. An electrostatic sensing device comprising an electrostatic sensing module comprising a first electrostatic sensing element, and a control unit electrically connected to the electrostatic sensing module is provided. The first electrostatic sensing element is one-dimensional semiconducting linear structure. A direct voltage is applied to the first electrostatic sensing element. A sensed object with electrostatic charge is moved to the electrostatic sensing device in a distance near but not touching the first electrostatic sensing element. A resistance changed value of the first electrostatic sensing element is measured.

Description

technical field [0001] The present invention relates to an electronic sensor, in particular to a method for electrostatic sensor sensing static electricity. Background technique [0002] In recent years, with the development of performance enhancement and diversification of various electronic devices such as mobile phones and touch navigation systems, electronic devices in which a light-transmitting touch panel is mounted on the front surface of display devices such as liquid crystals are increasing. A user of such an electronic device performs operations by pressing a finger, a pen, or the like on the touch panel while visually confirming the display content of the display device located on the back of the touch panel through the touch panel. Thereby, various functions of the electronic device can be operated. [0003] Some touchscreens can also recognize hovering motions, that is, by bringing a hand or stylus close to the touchscreen without touching the panel of the touc...
